Knowledge and skills of electric vehicle battery charging

1. Generally, the newly-purchased electric vehicle battery is new, and the capacity is large. The charging time will be longer, and it will reach more than 10 hours without changing the light. It will become faster and faster in the future, and it will be reduced to 6 hours after about 2 months. After that, it will be constant and can continue for about half a year, and the battery capacity will continue to decay, and it will overflow within 3-4 hours after 1 year. Of course, the battery is almost time to be replaced or maintained. 2. At present, electric vehicle chargers are all three-stage charging, which is divided into a constant voltage stage, a constant current stage, and a trickle stage. The first two stages are critical stages of charging. After the completion of the charging, the battery will basically overflow, the light will turn green, and enter the trickle stage. Protect the battery from being unplugged at this time. Continue to charge for 1-2 hours, which can effectively increase the battery life, but turns green. Do not exceed 8 hours afterwards. Charging skills: 1. Don't recharge after the battery is completely used up in the future. You must charge when the meter shows two lights left, which can effectively extend the battery life by 30%. 2. Don't overturn the charger with debris when charging, don't put flammable objects near the battery, and beware of fires. I have seen several cases. 3. After the light turns green, power off after charging for 1-2 hours. 4. Remember to plug in the battery end plug first, and then the mains plug when charging; pull out the mains plug first, and then the battery end plug after charging.
