Maintenance method of electric vehicle battery

How to protect your electric car battery from damage? The following is the maintenance method of electric vehicle battery that I sorted out, I hope it will help you!

Maintenance method of electric vehicle battery 1 1. Control the charging time to avoid overcharging.

Pay attention to the charging time. After the battery is exhausted, the normal charging saturation time is 8- 12 hours. We suggest that when charging the battery, users can continue to float for 2 hours after the charger turns green, and then they can end charging. But many users don't charge the battery every time, so the charging time should be controlled manually according to the usage and actual usage of the battery. If the charging time is not well controlled, more than two hours will be regarded as overcharge. Overcharging will slowly drain the battery. When the water loses to a certain extent, the battery will heat up when charging, and the charger will not turn green, giving users the illusion that the battery is not fully charged, so the battery will be very easily deformed. Once the battery is deformed, it means the end of its life.

2. Replenish the battery in time to avoid water loss.

When the battery is used for more than 12 hours after one year, if the charger still does not turn green, it may be caused by water loss of the battery. At this time, charging cannot be continued. You should take the charger and battery, find a professional maintenance point and replenish the battery with electrolyte, which can effectively prolong the service life of the battery. At the same time, the parameters of the charger are strictly tested. If the battery is seriously dehydrated due to the mismatch of charger parameters, the charger must be replaced immediately, otherwise even adding battery solution to the battery will not solve the problem.

Once the electricity is used up, it is no longer used.

Many users have encountered such a situation: after the battery is exhausted, they still use the rising voltage of the battery to continue riding for a short time. Although the mileage of riding in this way is not long, it is very harmful to the battery. This is a phenomenon that the battery is repeatedly overdischarged and seriously overdrawn, which is likely to damage the battery in a short time.

4. Pay attention to the charging environment to ensure safety.

This is ignored by many users. If the charging environment temperature is too high, normal chargers and batteries will also turn off the lights when charging. Therefore, the charging environment should meet the following conditions: ventilated and dry, not exposed to the hot sun, and the temperature should not be too high (preferably controlled near 25℃). At the same time, it should be noted that when the electric vehicle is charging, the body should avoid blocking the normal emission of gas to ensure safety.

5. Try not to use the battery frequently with high current, brake less, change speed less, and start from scratch.

If the battery is often used with high current, it will accelerate the aging of the battery and terminate its service life in advance. What's the use of high current? Many phenomena in use are heavy current, such as: starting suddenly, riding with load (carrying people and things), often going up steep slopes or driving in areas with poor road conditions, poor car condition (low tire pressure, tight brakes, aging lines) and so on. Therefore, users should always pay attention to and avoid them.

6. Avoid long-term battery shortage.

Because of its own characteristics, the battery has the characteristics of self-discharge, so even if it is not used after being fully charged, the battery's power will automatically drop after a period of time. If your electric car is not used for a long time, you need to fully charge the battery for storage. It is generally recommended to charge electric vehicles every ten days.

Finally, consumers need to be reminded that the service life of batteries for general electric vehicles is about 1.5-2 years on the premise of proper use and maintenance. If your battery has been used for almost two years, you should realize that its service life may have been reached. At this time, it is necessary to check more, do a good job of testing in advance, solve or replace problems as soon as possible when found, and avoid unnecessary troubles caused by sudden "squatting" of the battery during use.

Maintenance method of electric vehicle battery. Ride lightly to avoid being overweight and overloaded.

When riding an electric car, many people usually ignore their cars and often make them overweight and overloaded. In fact, this is very bad for the battery of the electric vehicle, because when the electric vehicle is heavily loaded, the battery will release a lot of current in an instant, which is easy to produce lead sulfate crystals, thus destroying the performance of the battery plate and affecting the charging and discharging ability of the battery. Therefore, please try to avoid overloading in daily use.

When the electric car starts uphill, the owner can use the pedal to assist, and try to avoid the sudden discharge of the battery with large current. When you forget to charge the car at ordinary times, when the car is out of power, the car is mainly driven by manpower, so it is forbidden to drive forcibly, because driving forcibly with electricity will also cause great damage to the battery.

2. Charge regularly to prevent the battery from dying.

Most electric car owners think that when they don't use electric cars for a short time, they just need to turn off the power and store them. In fact, this idea is not correct. Even if the power is turned off, the electric car will slowly die, because the vehicle itself has power-consuming equipment such as alarms. However, when the storage time is too long and the battery is exhausted, the battery will be in a state of power loss and easily sulfated, resulting in a permanent decline in battery capacity.

The longer the electric vehicle is idle, the more serious the battery damage may be. Therefore, when the electric car is idle, the owner should try to replenish the battery once a month to keep the battery healthy.

3. The charging time and duration should be reasonable.

Under normal circumstances, electric vehicles should be charged when the remaining power is about 20%, so the owner should try not to wait until the power is exhausted to avoid shortening the battery life due to "deep discharge". For careless electric car owners, you can install the electric car locator. After installation, if the car battery is low to a certain extent, Zhizhibao will remind the owner to charge it through the mobile phone, which can avoid forgetting.

Not only the charging timing is very important, but also the charging time is specified. After the battery is fully charged, cut off the power supply as soon as possible, because charging for too long will not only damage the battery, but also cause safety accidents. Don't worry if you install the smart cycling treasure, because the smart cycling treasure has the function of battery management, which can make the battery charge and discharge more scientific through its internal accurate calculation logic, thus prolonging the battery life.

4. The charging environment should be selected.

The best ambient temperature for charging the battery of electric vehicle is about 25℃, which is dry, ventilated and free from direct sunlight. Therefore, it is very wrong for many electric vehicle owners to push their vehicles back to their rooms for charging, which not only threatens their own safety, but also is not conducive to the vehicle battery. I suggest that car owners try to charge their electric cars in the planned charging piles in the community, which is not only good for the vehicle battery, but also can avoid potential dangers.

After the ambient temperature meets the requirements, the owner should also pay attention to the battery temperature. If the battery surface temperature is abnormal during charging, you must immediately cut off the power supply and contact professional maintenance personnel for handling. If you are worried that you have forgotten to check the battery, you can open the Zhizhibao APP to turn on the high temperature warning function. Once the battery temperature of the electric vehicle is abnormal, the mobile phone can receive a prompt, which is much more convenient.

Maintenance method of electric vehicle battery 3 1. Control the charging time to avoid overcharging.

Unlike lead-acid batteries, lithium batteries have fast charging conditions, so the charging time varies with different current chargers. Take a 48V20AH battery as an example. If equipped with 5A charger, it can be fully charged in less than 5 hours. If equipped with 10AH charger, it can be fully charged in about 2 hours. Therefore, it is forbidden to charge lithium batteries all night.

Maintenance suggestion: Many car owners actually don't unplug the power regularly. At this time, you can choose some switch sockets with timing, and set the charging time according to the battery capacity to avoid overcharging and damaging the lithium battery.

2. Avoid charging in high temperature and closed environment.

Lithium batteries are not so safe, especially ternary lithium batteries. Many car owners know that spontaneous combustion has a certain relationship with high temperature. Therefore, when charging the lithium battery electric vehicle, remember not to charge it in a high temperature environment, otherwise the closed space will form a high temperature environment, otherwise it will not only harm the battery, but also have potential safety hazards.

Maintenance suggestion: It is hot in summer, so try to charge it at night. At this time, the temperature is relatively low, which can reach the optimal charging temperature of 25℃ for lithium batteries. Moreover, try to avoid charging in a closed space.

3. Avoid charging at a temperature below 0℃

Although lithium battery has good low temperature resistance when discharging, low temperature is actually more harmful to the battery when charging, because once the temperature is lower than 0℃, lithium dendrites will precipitate from the lithium battery, which will not only affect the battery life, but also puncture the diaphragm in the lithium battery once it is too much, causing the danger of spontaneous combustion.

Maintenance suggestion: Compared with charging at night in hot days and charging in low temperature environment such as winter, try to choose daytime charging. In most parts of our country, even in winter, the daytime temperature is generally not lower than 0℃, which reduces the damage to lithium batteries.

4. Don't charge the bike immediately after riding it.

Through the above methods, we can see that lithium batteries, like lead-acid batteries, are both afraid of cold and heat, and lithium batteries will release heat during charging and discharging. In order to avoid overheating, the owner should avoid the electric car that has just finished riding and charge it immediately.

Maintenance suggestion: After the lithium battery is discharged, the battery heat will not disappear quickly. So it should be cooled for at least half an hour before charging. At this time, the superposition of charging heat and discharging heat can be reduced, causing damage to the lithium battery.

5. Leave it for a long time and don't fully charge it.

It is inevitable that electric vehicles will not be used for a while. Compared with lead-acid batteries, it is recommended to place them after being fully charged, while lithium batteries are different. Once the battery is fully charged, the voltage of the lithium battery will be unstable, and there will be safety factors, which the owner needs to pay attention to.

Maintenance suggestion: When the lithium battery electric vehicle needs to be placed for a long time, when the battery is charged, it can be charged to about 80% and unplugged. In this case, leaving it for three months will not cause too much damage to the lithium battery. Of course, if you leave it for too long, you still have to charge the battery halfway.
