Precautions for the use of lithium-ion battery chargers for electric vehicles and three taboos for lithium-ion batteries

Precautions for the use of lithium-ion battery chargers for electric vehicles 1. Do not randomly replace the original lithium-ion battery chargers. The parameters of the chargers for different models are basically different, and the replacement will cause damage to the car body. 2. Don't buy low-cost and low-quality chargers. The fans of low-quality chargers do not dissipate heat well and easily cause short circuits. 3. The charger should not be violently bumped. Strong vibration may cause the potentiometer inside the charger to drift, causing the charger to charge abnormally or even cause an accident. 4. Pay attention to the charging environment, overheating will overcharge, and too cold will undercharge. 5. No items are covered on the charger. The heat dissipation of the charger is helpful for charging safety and the life of the lithium-ion battery charger. Three taboos of lithium-ion batteries! At the first temperature, lithium-ion batteries are afraid of high temperatures. The second largest current, for example, the 18650 battery is 3C discharge, your electric car is 8000W, and the battery used is lower than the discharge current of your electric car, which will cause the lithium-ion battery temperature to be too high, the current is too large, and the life is shortened , There will be bulging scraps. If your electric car is very powerful and fast, it is recommended to choose 18650 batteries with 10C current. It is obviously very important to choose the right batteries! The third is full-charge storage. The full charge of the ternary lithium battery is 4.35V. At present, the protection board on the market is 4.2V and the charging is cut off. Therefore, many people buy lithium-ion batteries for electric vehicles and say that they have no nominal capacity. In fact, For this reason, it is generally best to store the lithium-ion battery of an electric car for a long time, and it is best to charge a 50-half of the TV. For example, if you buy a new mobile phone, most of it is powered by 50%. If the battery is fully charged and stored for a long time, the capacity of the lithium-ion battery will decrease. Except for lithium iron phosphate and lithium titanate, these two types can be stored at full charge. It should also be noted that the protection board of better quality should be selected. The biggest taboo of lithium ion batteries is overshoot and overdischarge, and ternary lithium overdischarge at one time. Just scrap, the overshoot must be scrapped too.
