How to maintain the new electric car battery for longer usage

1. The charging time for the battery car should not be too long. Overcharging will cause the battery to heat for a long time and speed up the scrapping of the battery. In theory, after complete discharge, the battery is charged at a nominal rate of 0.1 (standard battery charge), and can be fully charged in about 10 hours. Considering the efficiency of the charger and the depreciation of the battery, the general charging time can be between 10 hours and 12 hours. The limit should not exceed 16 hours. Many people have misunderstandings and think that the charger is smart charging. It doesn't matter how it is charged. Therefore, the charger is not disconnected for a long time, which not only damages the charger but also damages the battery.

2, the number of rechargeable batteries is limited, a good battery can theoretically reach about 1000 times, the general electric vehicle battery can be washed about 300 times is not bad. Therefore, try to recharge the battery when it is used up to extend the battery life. In addition, do not over-discharge, the battery is often severely under-voltage, and it will lead to accelerated scrapping. The new generation of controllers has under voltage protection, and older controllers may not have under voltage protection, so this situation requires special care to avoid frequent under voltage.

3, even if the electric car does not ride, the battery will also discharge, many electric cars will be placed in a week or two weeks will basically be discharged. Therefore, in order to protect the battery, in the case of not riding, charging once every week or two, the specific charging interval depends on the discharge speed of the battery. After going out for a year and a half, no one is using the car at home, so in the case of idle electric vehicles for a long time, it is best to remove the wiring of the battery pack, at least to remove the negative wiring, which can slow the slow discharge of the battery and protect Battery.

4, sometimes the charger is broken and need 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 advice buy the so-called fast charger. Although the standard charging speed is slower, it is beneficial to protect the life of the battery. Frequently charging quickly will accelerate the battery scrap. In addition, some advanced chargers have adjustable charging time, which means that the charging current or charging voltage can be adjusted to achieve fast charging, standard charging and slow charging. In addition to emergency vehicles, fast charging is not recommended.

5, electric vehicles often use battery packs, when the battery storage capacity is greatly reduced, many people often think of such a way to save money: only replace some of the storage batteries with the worst storage capacity (often It is to buy some used refurbished batteries for replacement, instead of using new ones. When replacing batteries, they often do not consider the specifications and brand of the battery, 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 scrapping, but also damage the motor and other components. To change the battery, it is best to replace the battery pack with a uniform size.

6, a lot of batteries used in electric vehicles, although known as dry powder batteries, in fact, not just dry powder batteries, just sealed maintenance-free lead-acid batteries. Due to the frequent overheating and acid leakage, some batteries are not used for a long time (until the battery is scrapped), and the storage capacity is often poor. This is not the battery scrap, but the battery internal electrolysis. Too little liquid, many people do not understand this reason, thinking that the battery is scrapped, often re-purchase the battery pack. In fact, the battery can be repaired by itself, the sealing cover is opened, and then the electrolyte is injected into the battery. Battery electrolyte replenisher is available in shops such as auto parts, auto parts, auto repair and repair.

7. After the electric vehicle is fully charged, in the event of power failure, first pull out the power plug of the charger, and finally pull the connection plug of the charger and the electric car. If it is reversed, it may burn out the battery or the charger, and it is more likely to burn out the charger. In addition, it is necessary to regularly check whether the electric vehicle's line is leaking or the insulation is broken, to prevent electric leakage from being injured when charging, and more importantly to prevent charging or short-circuit fire during driving, and the poor insulation of the line will also accelerate power consumption.

The line connector of the electric vehicle and the battery wiring should be checked regularly for looseness. The key point is to check the oxidation of the line connector. Once it is loose or severely oxidized, it will not only affect the driving performance, but also cause the line and battery to heat up and reduce the battery life. Seriously, it will also cause a fire.

8. Electric vehicles should not be parked in a humid environment, especially in corrosive environments such as chemical raw materials warehouses. Otherwise, metal parts and tires will accelerate corrosion and rust. In addition, try to avoid long-term sun exposure, which is easy to damage the tires and seat cushions.

9. Regularly check the braking performance to prevent traffic accidents caused by brake failure on the road. Regularly check the damage of the tires to prevent accidents during the exercise. Once the door locks and controllers are inflexible or occasionally fail, they must be repaired or replaced to prevent armpits when they go out.

10. When driving normally, ensure that the tire pressure is normal. If the air pressure is too high, it is easy to cause a puncture, especially in hot summer days. The chance of a fast puncture under high pressure is very high. The air pressure of the tire should not be too low. If the air pressure is too low, the tire will be crushed, the friction between the tire and the road surface will increase, and the power consumption will be too large.

11. Electric vehicles should not be overloaded frequently during normal riding to protect the frame of electric vehicles. The load-bearing capacity of electric vehicles is far less than that of motorcycles, but some people are used to moving the overload of motorcycles to electric vehicles. Once the frame metal is fatigued and breaks during exercise, it is likely to cause serious accidents. ?

Nowadays, electric bicycles have become the most convenient means of transportation for daily travel. They are quick and convenient to use, simple to operate, and deeply loved by the people. Experienced users know that the cost of electric vehicle batteries is the biggest consumption of electric bicycles. Everyone is very concerned about how to extend the life of electric vehicle batteries. If your electric bike has a long distance to travel every day, then you'd better charge it once a day. So how long is it best to charge each time? It is not good to charge the battery of the electric car for too long or too short. It is generally best to control it in 8 to 9 hours! There is also a very simple method, that is, when the red light of the charger is converted to green light, it can be unplugged after another one or two hours. Because the indicator light indicates full charge, the electric vehicle battery charge may reach 97% to 99%. At this time, the electric vehicle battery is not really full, and it can be fully charged after floating for two hours! The charger of the battery must use a special charger that matches the model of the electric vehicle battery. Do not replace the charger at will, because the charging voltage of each brand of battery has a certain error. The dedicated charger is adjusted by the manufacturer according to the battery. If you change the charger at will, it is likely to cause damage to the battery! In order to better protect the battery, your electric car is best to use the pedal boost when starting, manned, uphill and power shortage, to avoid the battery's instantaneous high current discharge. In the case of severe power shortage of the electric vehicle battery, it is necessary to get off the vehicle and timely replenish the battery. The following are some maintenance methods for the battery: First, the electric vehicle battery should be installed firmly on the electric bicycle to prevent the battery from being damaged by vibration during riding. Second, always remove dust and dirt from the battery cover, and keep the battery dry and clean to prevent the battery from discharging itself. Third, the battery cannot be in a state of insufficient power for a long time, it is a good habit to timely charge the battery when the battery is insufficient. 4. When the electric bicycle is just starting, it should be started with the pedal boost to avoid damage to the battery due to excessive discharge current. 5. When riding, pay attention to the serious over-discharge of the battery. Excessive discharge may cause serious battery power loss, thus greatly shortening its service life. The under-voltage protection function is generally provided on the electric bicycle. When only one display light is on, the battery should be charged immediately to avoid excessive discharge of the battery. Sixth, it is necessary to check the link line of the electric vehicle battery frequently, so as to avoid the battery short circuit caused by the looseness of the line, and the danger occurs! Electric car battery maintenance method: Any tool, only love it, take care of it, you can use it for a longer time, electric car battery is no exception, in the electric car to bring you convenience and speed, you also want Perform some necessary maintenance on the electric vehicle battery. When it comes to the maintenance of electric vehicle batteries, most people still know very little about it. In fact, the electric car battery should be well maintained, the first way to use the correct charging method. At present, most electric vehicles use lead-acid electric vehicle batteries, which can be directly charged and do not need to be recharged.

Charging pay attention to heat dissipation in the summer, do not charge in the sun, and all electric vehicle batteries should be recharged, the charging time is best not to be too long, do not exceed 12 hours, so that the depth of discharge and life is very large The relationship is how much electricity is in your battery, which is why you are charging. The battery must not be in a deficient state when it is stored. The deficient state means that the battery is not charged in time after use. When the battery is stored in a depleted state, it is prone to sulfation, and the lead sulfate crystals adhere to the electrode plate, blocking the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle state is idle, the more severe the battery is damaged. Therefore, when the battery is not in use, it should be replenished once a month, which can better maintain the health of the battery.

Skills are strictly prohibited when stored

The battery must not be in a deficient state when it is stored. The deficient state means that the battery is not charged in time after use. When the battery is stored in a depleted state, it is prone to sulfation, and the lead sulfate crystals adhere to the electrode plate, blocking the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle state is idle, the more severe the battery is damaged. Therefore, when the battery is not in use, it should be replenished once a month, which can better maintain the health of the battery.

In the course of use, if the mileage of the electric vehicle suddenly drops by more than ten kilometers in a short time, it is very likely that at least one battery in the battery pack has a short circuit, such as a broken grid, softening of the plate, and falling off of the active material of the plate. . At this time, you should go to the professional battery repair organization for inspection, repair or matching. This can extend the life of the battery pack relatively and save the maximum cost.

When the electric car starts, carries people and goes uphill, please use the ankle to assist, try to avoid instantaneous large current discharge. High current discharges tend to cause the formation of lead sulfate crystals, which impair the physical properties of the battery plates.

Electric vehicles cannot be left outside when it rains, which can easily lead to paralysis and too many times easily broken. Not good for battery maintenance.

Always pay attention to the quality of the charger and whether it is damaged to avoid a certain impact of the maintenance of the electric car and the burning of the battery.
