(1) Lithium ion battery is afraid of high temperature due to high temperature. The service life of lithium ion battery will be greatly reduced if it is in an overheated environment for a long time. In severe cases, an increase in internal pressure can cause an explosion. Even if there is no explosion, the lithium-ion battery will be scrapped quickly under high temperature, mainly because of the high temperature of its working environment

(2) High current, for example, 18650 battery is 3C discharged, while your electric vehicle is 8000w. The battery used is lower than the discharge current of the electric vehicle, which will lead to excessive temperature, current, short service life, expansion and scrapping of the lithium-ion battery. If the power of your electric vehicle is very high and the speed is very fast, it is recommended to choose the 18650 battery with a current of 10C. It is obviously important to choose the correct battery

(3) When the battery is fully charged, the full charge of the ternary lithium battery is 4.35v. At present, the protective plate on the market is 4.2V, so many people say that the lithium-ion battery of electric vehicles is not as large as the nominal capacity. In fact, that is why. Generally speaking, it is better to store the lithium-ion battery of electric vehicles for a long time and fill 50% of the TV. For example, when buying a new mobile phone, many batteries are 50% of the power. If the battery is stored at full power for a long time, the capacity of the lithium-ion battery will be reduced. In addition to lithium iron phosphate and lithium titanate, they can be stored at full power. It should also be noted that good quality protection boards should be selected. The biggest taboo of lithium-ion batteries is overshoot and overshoot. Ternary lithium is scrapped due to one-time overshoot, and scrapped due to overshoot

(4) For proper charging equipment, the current of the charger and the total current load of the electrical equipment shall be within the specified range during charging and discharging. Excessive current load is easy to cause internal short circuit of the battery, thus damaging lithium ion and causing potential safety hazard of the circuit. The same principle applies to the voltage of a rechargeable charger. Therefore, pay attention to whether the charger is qualified when using it.
