Battery maintenance of electric vehicle on the charging layer

　　a) During night charging, the average time is about 8 hours to avoid overcharging and under charging.

　　b) When charging, the display light indicates that you don't need to unplug it immediately when the grid is full, and float for another 2-3 hours.

　　c) Fill it with electricity as much as possible at once. If it is really necessary to ride in the whole process of charging, it should be filled immediately after cycling.

　　d) Frequent charging is beneficial to the service life of the circulating system, but at this stage, many chargers used in commodity circulation in the market have some disadvantages, such as high equipment failure rate, poor stability, poor precision and so on. Therefore, sometimes frequent charging endangers the service life of the battery. If the battery is discharged and recharged, it is likely to lead to overcharge and discharge of some single cells, and the charging acceptance capacity of the battery with power loss will be greatly reduced, resulting in a common failure of charging. In addition, because the battery is discharged and recharged, the charging load will take a long time, which is easy to damage the charger. Therefore, it is more useful to charge once when the battery releases 50-70% of the power consumption, which is good for the service life of the battery.
