Although electric vehicles are not eye-catching, they obviously occupy a large part of our lives in congested and noisy urban life. Do electric vehicles also need maintenance? It should be replaced like a mobile phone after two years of riding, but for those who are interested. It is said that electric cars can be cared for like private cars. Next, China Electric Vehicle Manufacturers will introduce the maintenance skills of electric bikes:
The three core components of electric vehicles: battery, controller, and motor. When the electric vehicle is made into a finished product, we try not to modify it privately, such as installing a battery pack, and the current and voltage of the controller and the motor are not working within their normal range, which will affect their life.
When charging, you should first connect the output end to the electric vehicle and then plug the plug into the power supply to charge. The reverse is also true, when charging is complete, first, unplug the power supply and then unplug the output connector.
The charging time for the battery is generally 8-10 hours. The charging is based on the additional 2 hours after the green light of the electric car charger is on. The first time the electric car is charged, after the power is exhausted, it can be charged for two more hours on the basis of full charge.
It is best not to increase the "throttle" when the electric vehicle starts. One is because the instantaneous current is too large and it may cause accidents, and the other is because the excessive power consumption also damages the battery. Do not wait until the last bit of electricity is exhausted to recharge the electric vehicle. , The standard of measurement is 30% of the total power. Don’t drive the electric car forcibly when the battery is dead, which will damage the battery.
For the braking method of electric vehicles, the braking sequence should be one after the other and the front brake. No matter how urgent the situation is, don’t slam the brakes. Slightly hold the brakes slightly, especially when the disc brakes are installed. After all, electric vehicles are two-wheeled, emergency brakes. It will cause the electric vehicle to sway irregularly and easily cause a safety accident. There is also tire grinding that will greatly reduce the life of the tire.
Do not ride an electric bike too fast when the road conditions are bad. It is a trivial matter to destroy the car, and it is easy to pierce nails under such road conditions. When the speed is slow, the probability tends to be much smaller.

China Electric Motorcycle Factory Introduces The Maintenance Skills Of Electric Vehicle Batteries
2021年5月19日Under normal circumstances, electric vehicle batteries have to be replaced after one or a half years of use. Below, China Electric Motorcycle Factory introduces how to maintain electric vehicle batteries in daily life in order to extend the life of electric vehicle batteries?
First of all, try to avoid overloading and overweight driving (such as riding a bicycle with people or loading heavy objects, etc.). If you find that the meter’s battery display is insufficient during the process of traveling, you must use manpower to ride at this time, so that deep discharge will cause loss of battery life.
Pay attention to the charging method of the car battery. When charging a newly purchased battery for the first time, it must take a long time to ensure that it is fully charged. For lead-acid batteries, regardless of distance, charge them immediately after use, and charge them as soon as they are discharged. Don’t think of charging until the battery is completely exhausted. If the car is not used for a long time, make sure to recharge it once a month. This not only protects the battery, but also prolongs its service life.
Try to avoid sudden braking when electric vehicles are driving. Frequent sudden braking will affect braking flexibility and consume battery capacity; the faster the vehicle, the greater the loss of the battery.
Do not use the motor to start the car directly when it is at a standstill. It is best to start the car by stepping on it while assisting. When going up the bridge, going uphill, or driving against the wind, you must use the pedals to help avoid impact damage to the battery and affect the continued mileage and service life of the battery.

China Electric Vehicle Manufacturers will teach you how to prevent battery over-discharge?
1.Strengthen maintenance and charge in time: During the maintenance process, pay attention to the cleanliness of the battery and frequently check for damage. In addition, after the battery is used, if it is found that the battery power is less than 30%, it must be charged in time, and avoid excessive use of the battery.
2.Handle with care: The electrolyte in the battery of the electric car is very important, so it must be handled with care during handling to avoid collision and damage to the case, resulting in electrolyte leakage.
3.Always check the vehicle to ensure the safety of use: During the use of electric vehicles, various faults will occur with the extension of the time limit for the circuit and various parts, which will seriously affect the mileage and shorten the service life. Therefore, it is necessary to regularly check various components inside the vehicle and find that there is rust or the line is oxidized, and it should be replaced in time.
4.Prevent moisture: During the riding of electric vehicles, if you don’t pay attention, if it encounters rainy days, or road surface water, the battery box is prone to water ingress, causing a short circuit of the battery and causing self-discharge. Therefore, in this situation, try to avoid wading or direct rain, and at the same time regularly check the inside of the battery box and find that there is direct cleaning of the accumulated water to keep the battery box dry.

China Electric Vehicle Manufacturers introduces battery maintenance methods for battery vehicles:
1. The charging time for the battery car should not be too long. Overcharging will cause the battery to heat up for a long time and speed up the scrapping speed of the battery. Theoretically, after fully discharged, the battery is charged at a nominal rate of 0.1 (standard battery charge), and it can be fully charged in about 10 hours. Considering the efficiency of the charger and the depreciation of the battery, the general charging time is between 10 hours and 12 hours. , The limit should not exceed 16 hours. Many people have misunderstandings, thinking that the charger is smart charging, and it doesn’t matter how it is charged, so if the charger is not disconnected for a long time, it will not only damage the charger, but also damage the battery.
2. The number of times the battery can be charged is limited. A good battery can theoretically reach about 1000 times. A general electric vehicle battery can charge about 300 times. Therefore, try to recharge when the battery is used up to extend the service life of the battery. In addition, do not over-discharge. The battery is often under-voltage seriously, which will also lead to accelerated scrapping. The new generation of controllers have under-voltage protection. Old-fashioned controllers may not have under-voltage protection. Therefore, special attention should be paid to avoid frequent under-voltage protection in this situation. Pressure.
3. Even if you don’t ride an electric bike, the battery will discharge. Many electric bikes will basically be discharged within a week to two weeks. Therefore, in order to protect the battery, if you are not riding the bicycle, you must charge it once a week or two weeks. The specific charging interval depends on the discharge speed of the electric car battery. If you’re out for a year and a half without a car at home, if the electric vehicle is left idle for a long time, it’s best to disconnect the battery pack connection, at least the negative connection, so as to slow down the battery’s slow discharge and protect it. Battery.
4. Sometimes the charger is broken and needs to be replaced. It is best to re-purchase the charger according to the output parameters of the original charger. Do not listen to other people’s suggestions and buy the so-called fast-charge charger. Although the standard charging speed is a little slower, it is helpful to protect the life of the battery. Frequent fast charging will speed up the battery scrap. In addition, the charging time of some advanced chargers is adjustable, that is, the charging current or charging voltage can be adjusted to achieve fast charging, standard charging and slow charging. Except for emergency vehicles, fast charging is not recommended.
5. Electric vehicles often use battery packs. When the battery’s power storage capacity is greatly reduced, many people often come up with such a method in order to save money: only replace some of the batteries with the worst power storage capacity (often It is to buy some second-hand refurbished batteries for replacement instead of new ones). When replacing the batteries, the specifications and brands of the batteries are often not considered, as long as the output voltage is consistent. This is not recommended. The battery specifications are not uniform, which will not only speed up the battery scrap rate, but may also damage the motor and other components. To replace the battery, it is best to replace the entire battery pack with a uniform specification.
6. Although many batteries used in electric vehicles are called dry powder batteries, they are not just dry powder batteries, but sealed maintenance-free lead-acid batteries. Due to frequent overcharging and heat generation, the acid leaks out. Some batteries often have poor storage capacity after being used for a short time (far from the time the battery is scrapped). In this case, the battery is not scrapped, but the battery is electrolyzed. Too little liquid, many people do not understand this reason, thinking that the battery is scrapped, often repurchase the battery pack. In fact, this kind of battery can be repaired by itself, just pry open the sealing cover, and then pour electrolyte into the battery. The battery electrolyte replenisher is sold in stores such as auto parts and motorcycle parts.

Electric Vehicle Manufacturers introduces how to properly maintain batteries:
1. Prevent excessive discharge
When the battery discharge termination voltage, the internal resistance is large and the electrolyte concentration is very thin, especially in the plate hole and surface, the internal resistance has a tendency to heat up during discharge, and the volume expands during discharge. When the current is large, it heats up obviously, and the lead sulfate concentration is especially high at this time The crystal branches cause a short circuit and the performance increases. Moreover, the lead sulfate will crystallize into larger particles at this time, that is, inverse sulfation, which further increases the internal resistance, the charge recovery ability is poor, or even cannot be repaired. The battery should be used to prevent excessive discharge. Effective measures for under-voltage protection. In addition, because the under-voltage protection of electric vehicles is controlled by the controller, some equipment outside the controller, voltmeters, indicator lights, etc., power-consuming appliances are directly powered by the battery, and their power supply is generally controlled by the controller. Switch), although the current is small when it is closed, it will be over-discharged if it is discharged for a long time (1~2 weeks), so it should be turned off immediately when it is necessary to open the lock for a long time.
2. Prevent overcharging
The parameters of the charger should be well-matched with the battery. It is necessary to fully understand the operating conditions of the battery in high-temperature seasons and the changes during the entire service life. The battery should be placed in an overheated environment during use. Especially when charging, it should be kept away from heat sources. Charge the battery when the battery temperature returns to normal. The battery installation position should ensure good heat dissipation. Stop charging when it is overheated. Check the charger and battery. Shorten the charge when the battery discharge depth is shallow or the ambient temperature is high. time.
3. Prevent short circuit
When the battery is short-circuited, its short-circuit current reaches hundreds of amperes. The stronger the contact, the greater the short-circuit will cause the current, so all the connections will generate a lot of heat, and the weaker links will generate more heat, which will cause the connection to fuse and cause a short circuit. The battery can locally produce explosive gas (or store explosive gas during charging), and sparks will occur when the connection is fused, which will cause the battery to explode; if the battery is short-circuited, the time is short or the current is particularly large, it can cause the connection to fuse, so When the battery will definitely cause a short circuit, you need to stop it in advance.
4. Prevent the connection from loosening and sticking
If the degree of contact is light, conduction will occur, causing the line contact parts to heat up, line loss, and large output voltage, which affects the motor power, reduces the mileage, or can ride normally; if the terminal parts are in tight contact, The terminal will generate a lot of heat, which will affect the bonding between the terminal and the sealant. The phenomenon of liquid leakage and acid creep will occur for a long time. If the phenomenon of contact sticking occurs during driving or charging, strong sparks will be generated. Therefore, it is necessary to check these dangers carefully during daily use.

No matter how good the refurbished battery of electric vehicles is, there are flaws. Inexperienced ones need to compare with new batteries to distinguish between true and false. Electric Vehicle Manufacturers will introduce how to choose high-quality batteries.
1. Look at the appearance: The appearance of the new battery is smooth and clean. The surface of the refurbished battery has been polished to remove the original mark, repainted, and re-marked and dated. If you look closely, you can see the marks and date labels that were polished off the original battery.
2. Look at the terminal: there is solder residue in the terminal hole of the refurbished battery. Even if it is cleaned, it can be seen that there are traces of grinding. The new battery is bright. Some refurbished batteries have replaced the terminals, but the positive and negative poles are marked unevenly with the color paint, and there are signs of refilling.
3. Look at the production date of the battery. If it is refurbished, the production date will generally be erased and battery scratches will appear.
4. Look at the anti-counterfeiting label and QR code of the battery. Regular new batteries must have anti-counterfeiting labels. When necessary, scrape off the battery’s anti-counterfeit label coating or scan the two-dimensional code on the battery to check the actual situation to determine the authenticity.
5. Generally, new batteries will not have battery "bulge" phenomenon. When replacing, press the battery shell several times to see if there is any bulge.
6. "Value for money". When replacing the battery, it is best to go to a regular after-sales or regular battery store to replace it. Remember to ask for an invoice.

Electric Bike Manufacturer introduces how to properly charge electric bike batteries?
First, electric vehicle batteries do not need to be charged too diligently
The rechargeable battery itself also has its life. The number of times it can be charged from production to scrapping is also limited. Basically, it can be said that one charge is one less time. The user should reduce the number of battery recharges as much as possible under the conditions that can guarantee normal driving the next day. If driving consumes 30% of the power for a day, then it is not necessary to charge that night, and the remaining 3% after get off work the next day Recharge at about ten. However, as a well-known domestic battery manufacturer, Xupai battery itself has a longer service life and more stable performance. The large-capacity design structure can still run a long way even if it uses 30% of the power.
Second, the charging operation should be correct
Generally, the charger is connected to the power supply first, and then the charger is plugged into the power socket. If the charger is connected to the power socket and then the battery, it will easily cause ignition and the insulation layer outside the battery will be burned. , Causing a short circuit of the circuit, causing the battery to be scrapped.
Third, the charging time of the battery must be grasped
In principle, the rechargeable battery can be recharged for two hours after it is fully charged. It is not necessary to charge the battery for a long time. When the indicator light of the electric vehicle charger has turned from red to green, it means that it is fully charged.
Through the above introduction, Handicap E-Tricycle Manufacturers hopes that you can simply refer to the content of this article in future use.

Electric Vehicle Manufacturers Explains Why Batteries Need To Be Deeply Discharged Regularly
2020年11月25日Electric Vehicle Manufacturers introduced that the batteries of electric vehicles need to be deeply discharged regularly:
A regular deep discharge of the battery is also beneficial to "activate" the battery, which can slightly increase the battery capacity. The general method is to fully discharge the battery periodically. The method of full discharge is to ride the bike to the first undervoltage protection under normal load conditions on a flat road. Note that we especially emphasize the first undervoltage protection. After the battery is under-voltage protection for the first time, after a period of time, the battery voltage will rise and return to the non-under-voltage state. At this time, if the battery is used again, the battery will be seriously damaged. After the complete discharge, the battery is fully charged. You will feel the battery capacity has improved.
Pay attention to the charging environment: the best environment temperature for charging is 25°C. At present, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging at 25°C is better. Otherwise, the problems of undercharging in winter and overcharging in summer are inevitable. When the ambient temperature is really 25°C, it is relatively low, so there must be a problem of overcharge in summer and undercharge in winter. Fortunately, most households now have the conditions for indoor temperature regulation. In this way, when charging, it is best to arrange the battery and charger in a ventilated and temperature-regulated environment. It is particularly reminded that when the battery is in the northern winter and enters a warm room at a low outdoor temperature, frost and condensation will appear on the surface of the battery. In order to avoid battery leakage caused by frost and condensation, you should charge the battery after the battery temperature rises to close to the indoor temperature and is dry!

Electric vehicles have now become an indispensable means of transportation in life. Basically, every family has one. Do you know how to charge it correctly? Many people don’t know whether the battery of an electric vehicle should be recharged when it is dead or whether it should be charged when it is slightly insufficient. Now there are more and more friends riding electric bikes on the street, but few know the correct way to charge the battery of electric vehicles. Today, the Sport High Power E-Bike Supplier will introduce how to charge the electric vehicle battery:
1. It is necessary to keep the battery fully charged and ride the electric moped every day, no matter 10-50km, it should be recharged, so that the battery is in a "full state" for a long time, and the battery is charged on the same day. The plate vulcanization occurs and the capacity decreases.
2. Perform regular deep discharge: It is recommended that you perform a deep discharge after two months of use, that is, ride for a long distance until the under-voltage indicator flashes and the power is exhausted, and then charge to restore the battery capacity, which also allows you to understand the battery Whether the current capacity level needs to be maintained and protected.
3. It is forbidden to store under power loss: storage under power loss will seriously affect the service life. The longer the idle time, the more serious the damage to the battery.
4. Regular inspection: If you buy a new car with a continuous mileage of 50km, there will be a serious reduction in the continuous mileage within March, such as more than ten kilometers. At this time, you can use a multimeter to check the voltage value of the battery external terminal. Generally, it should be 39 -42V, if the voltage is less than a few volts, or if the voltage of one battery in the battery box is lower than 10.5V, the internal single cell may be short-circuited. At this time, you should find a repair station to repair and replace, so as not to damage the other two good batteries. Also check the charger for malfunctions.
5. The designed load capacity of the electric bicycle is 75kg, so avoid carrying heavy objects. Please use your pedals to help when starting and climbing. Because the motor current increases at this time, the battery discharges too fast and the voltage drops rapidly. The smaller the depth of discharge of the battery each time, the longer the service life of the capacitor. Therefore, reducing high-current discharge can extend battery life and increase mileage. In addition, no matter how large the battery pack is, users should develop a good habit of charging as soon as they are used.
6. It is normal for the battery capacity to decrease with the temperature in winter. Taking 20℃ as the standard, the general -10℃ capacity is 80%.
7. Keep the battery surface clean for a long time. Exposure to the sun is prohibited when storing the car. The car should be placed in a cool, ventilated and dry place.

3 reasons and troubleshooting methods for Fast Sport Electric Motorbike wheels not turning
1. The faults of electric bicycle motors
If you wake up in the morning and find that the electric bicycle cannot be started, don’t worry, first make sure to open the electric door lock when the battery is charged, and use a multimeter to measure the voltage of the motor lead. At this time, you can quickly determine what is wrong with the electric bicycle.
The detailed inspection method is: use a multimeter to measure the DC gear of the controller (2, 3) or the motor lead, and turn the speed control knob to measure whether there is voltage, and you can easily detect the fault.
If the measurement result is voltage, it can be determined that the motor is broken or the lead wire from the controller to the motor is broken; if the measurement result is no voltage, it can be judged at this time: the control circuit of the electric bicycle is faulty.
2. Brake switch and controller
Disconnect the brake power plug of the controller, and then turn the power switch.
If the electric vehicle can rotate, it is judged that the brake switch is broken and a short-circuit fault has been caused. Replace the brake switch;
If the car does not turn, use a good speed control handle to replace the original one. If the car rotates, it is determined that the original speed control handle is broken, causing the electric car to not rotate, and a new controller should be replaced.
3. Battery box contacts
Measure the contacts of the battery box to immediately identify the cause of the car not turning due to the power supply.
The measurement method is to measure the contacts of the battery box with a multimeter in the DC gear to see if there is a voltage display. If there is no voltage display, open the power lock and the indicator on the instrument panel does not light up, it is judged: the fuse fuse is broken, the fuse should be replaced, the wire is off, the welding is broken, or a new wire should be replaced;
If there is a voltage display, turn on the power lock and the indicator on the instrument panel does not light up, then it is determined that the power lock is broken, just replace it with a new lock without powering on.

Electric Vehicle Manufacturers introduce why the batteries of electric vehicles are deformed.
The deformation of an electric vehicle battery is not sudden but often has a process. When the battery of an electric vehicle is charged to 80% of its capacity, it enters the high-voltage charging area. At this time, oxygen first precipitates on the positive plate, which passes through the holes in the separator and reaches the negative electrode. Oxygen reactivation reaction is carried out on the negative plate: 2Pb+O2 (oxygen) =2PbO+Q (heat) PbO+H2SO4=PbSO4+H2O+Q (heat). Heat is generated during the reaction. When the charging capacity reaches 90%, the oxygen generation speed increases and the negative electrode begins to generate hydrogen. The increase of a large amount of gas makes the internal pressure of the battery exceed the valve pressure, the safety valve opens, and the gas escapes, finally showing water loss. 2H2O=2H2↑ +O2↑ . With the increase of cycle times of the battery, the moisture gradually decreases, and the battery is easy to deform. Causes the battery to deform as follows:
1. the oxygen channel becomes unblocked, and the oxidation produced by the positive electrode can easily reach the negative electrode through the channel;
2. The heat capacity is reduced, and the largest heat capacity in the battery is water. After water loss, the heat capacity of the battery is greatly reduced, and the generated heat makes the battery temperature rise rapidly;
3. Due to shrinkage of superfine glass fiber separator in the battery after a water loss, the adhesion between the separator and positive and negative plates becomes worse, the internal resistance increases, and the calorific value increases during charging and discharging. After the above process, the heat generated in the battery can only be dissipated through the battery slot. If the heat dissipation is less than the calorific value, the temperature rises. With the increase of temperature, the overpotential of battery gas evolution decreases, and the gas evolution increases. A large amount of oxidation at the anode passes through the channel and reacts on the surface of the cathode, giving off a large amount of heat, which makes the temperature rise rapidly and forms a vicious circle, namely the so-called thermal runaway.
