How to check the life limit of lithium battery?

1. Lithium batteries of electric vehicles need to be stored in a cool place, neither refrigerated nor stored in high temperature areas. Temperature has a great hazard to the battery capacity of the lithium battery in the car. The embrittlement rate of lithium batteries is determined by temperature and battery charging conditions. High battery charging conditions and increased temperature will accelerate the reduction of battery capacity. If the battery is placed at a high temperature after it is fully charged, it will cause great harm to the battery. Therefore, for long-term storage, the best treatment is to charge the battery to 40% and store it in a cool place, so that the battery's maintenance power supply circuit can operate within the long-term warranty period. 2. Lithium batteries for electric vehicles should minimize frequent and thorough charging and discharging. Some cars equipped with lithium batteries will be damaged prematurely because of too low charge and discharge. When the battery rechargeable battery is placed below 2.5 amps per module, the safety power circuit inside the battery will start, and the battery will not work well at first. However, if the battery drops below 1.5 amps per module and lasts for a period of time, for safety reasons, the battery can no longer be recharged. Therefore, if you want to store it for a long time, you need to charge the battery, and you have to charge it once a month thereafter. 3. Lithium batteries of electric vehicles should be recharged frequently at fast charging stations. For better convenience, some customers often go to some streets to quickly charge the batteries of electric vehicles. But I don't know that this will not only reduce the battery life of electric vehicles, but also continue to plant safety risks. The rate of attenuation coefficients of various characteristics of lithium batteries will be accelerated during fast charging, which often causes the battery to be unable to fill up and become full. If you don't pay attention, it is very likely to cause overcharging and uncontrollable heat, which will cause a short circuit and cause a safety accident. Therefore, to charge the lithium battery, it is necessary to use a genuine battery charging head to charge the battery according to the standard method as much as possible, that is, slow charging.
