① When the remaining charge is 20%-40%, the charging speed is the fastest and the efficiency is the highest.  

②  Usually, the car should try to be between 20%-80% power, and the charging strategy of slow charging and fast charging can prolong the life of the battery pack.

③ Recommend charging immediately after the end of the car, because at this time the battery temperature is relatively high, can improve the charging performance.  

When charging to 80%, the speed will slow down, because the power battery will switch to trickle charging mode when charging to high level, and the end charging time will be prolonged, and the estimated remaining charging time shown by the meter will be deviated.  In addition, the power battery in high temperature or low temperature, the charge and discharge capacity will be weakened, charging time becomes longer, is a normal phenomenon.  

If it is the first use of a new car or after a long time of parking, the residual electricity (SOC) displayed by the instrument may be deviated, it is recommended to first full charge the vehicle.  

When the vehicle is not used for a long time (more than 7 days), it is recommended to keep the battery power at 40%~60%, which will prolong the service life of the power battery;  

More than 3 months not to use, every three months for power battery discharge of the reentry after filled to 40% ~ 60%, otherwise it may cause power battery discharge, reduce the battery performance and even damaged, the resulting vehicle failure and damage, if long time not to use other vehicles, it is best to vehicle parking in the underground garage, warm libraries such as higher temperature area,  In order to reduce battery heat loss, ensure vehicle performance.  

When charging the car in rainy days, pay attention to the whole process of not letting rain into the charging parts and interfaces, and ensure that the charging port and charging gun are dry.  It is not recommended to charge your vehicle outdoors during heavy rain or thunderstorms.
