First, don't discharge too deeply.
In fact, to put it bluntly, don't use the electricity of the vehicle too much, or you will spend money and time to rent a trailer. Moreover, this is not a good thing for the battery itself, so I suggest recharging your vehicle battery when it is used to a certain extent or has charging conditions, so that the battery life will not be damaged by overcharging in a half-charged state.
Second, don't charge too much, and don't charge too long.
Although today's electric vehicles have the function of battery protection, for example, if you keep plugging in the charging pile, it will trip automatically when fully charged, and even there is redundancy protection, but there are still many new forces in our country, and these things are sometimes not handled very well. For example, it is reported on the Internet that Weilai has a car because it has been charging. So I suggest you unplug the battery in time when it is fully charged, or set an alarm clock for yourself to remind you to unplug it, which is also good for the battery of the electric car.
Third, pay attention to the ambient temperature of battery charging.
Friends in the south don't have to worry too much. The coldest time is around zero. In fact, under normal circumstances, the better charging temperature should be between 0 and 45 degrees. For example, when it is below zero, in extreme cases, it is recommended not to do fast charging first. You can use slow charge to keep the battery in good condition first, and then fast charge will be better. In addition, it is not recommended to do fast charging in hot summer, because it will increase the overall thermal management load of the battery, so it is recommended that you charge it in an ordinary way.
Fourth, check whether the charging gun and charging port are clean before charging.
Before charging the electric car, be sure to check these, and don't have stains, mud or snow sticking to them, which is bad for the electric car. Also, when it rains heavily, even if you are in a hurry, you must not charge the electric car, because it is a very risky thing.
Some car owners are used to charging the battery first, then using it all, recharging it again, and activating the battery several times. This operation is professionally called lithium battery "formation". In fact, this is a process that must be completed before the electric tram leaves the factory, and it is not necessary for the owner to do so.
However, it is mentioned in Automotive Big Data Application Research Report (202 1) that current capacity and charge-discharge depth are the main parameters to characterize the health of the battery, and current capacity is the maximum capacity that can be accommodated at present, while charge-discharge depth is the percentage of charge-discharge capacity to the rated capacity. With the increase of charge and discharge depth, the activated active substances in the battery increase and the discharge power increases, which makes the health of the battery decline more obviously.
