The correct charging method for electric vehicles

1. Placing and recharging the battery when driving for the first time. The lithium-ion battery pack of electric vehicles has some remaining power before leaving the factory. Like lithium battery electric bicycles, you must use the battery to fill up the battery before driving on the road for the first time. The sluggish power of the battery may appear to be weak when driving the car and cause damage to the battery; 2. Matters needing attention in the selection of the charger The original standard charging piles of electric vehicles are basically low-power slow charging, pure Electric EV models are equipped with more power and are more suitable for charging electric vehicles strictly speaking. However, because charging stations are very popular now, fast charging stations that can be fully charged in 1 hour are everywhere, but in the first few times of charging The author does not recommend the use of fast charging to charge electric vehicles. It is still recommended to use slow charging to reactivate the battery within 10 times, which will be more conducive to the extension of the life of the lithium battery of electric vehicles; 3. Charge the electric vehicle in time. When the battery power is lower than 30%, it is necessary to consider charging. Although there is still a lot of power at 30%, when the battery power has been lower than 20%, it is strongly recommended to fill the battery before driving; 4. Pay attention to the charging environment The best ambient temperature for charging is 25°C . At present, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging at 25°C is better. This is relatively easy to achieve in the south. In winter, the temperature in the north may be below zero for a long time. Generally speaking, the battery of electric vehicles has an automatic temperature control system. The battery will be preheated during charging. Because the voltage and current of electric vehicle charging are very high. High, so it is strictly forbidden to touch water when charging, especially near the charging port, otherwise it is very dangerous; 5. Charging time for the first charge The first charging time of an electric car is not too mandatory, and it is not special whether it is fully charged or not fully charged. Important, but the activation action of charging is indispensable; Disclaimer: Some pictures and content of articles published on this site are from the Internet.
