Charging method 1: The electric vehicle battery must be fully charged every time it is charged. It cannot be used every time it is fully charged. As a result, the battery is often not full, so the battery damage to the electric vehicle is very large, which will shorten the service life.
Charging method 2: Under normal circumstances, the electric vehicle battery is charged at night, and the average charging time is about 8 hours. If it is a shallow discharge (the mileage after charging is very short), the battery will soon be full. If it continues to charge, it will overcharge, causing the battery to heat up and reduce the battery life. Therefore, the electric vehicle battery has a discharge depth of 60% - 70% (two grids of electricity), and the charge is best when it is used. In actual use, it can be converted into a riding mileage, and the necessary charging is performed according to the actual situation to avoid harmful charging. Deep discharge once a month (to under-voltage is charged).
Charging method 3: 8 hours in winter and 6 hours in summer. Under normal circumstances, the full reference is: 1 hour or so after the charger is turned on, no more than 2 hours is the best. According to the old and new battery, the charger is generally designed to be fully charged in 8 to 10 hours (referring to the long distance of riding, the battery discharge is close to undervoltage), and there are also automatic stop charging after 8 hours on the market. (This is a danger of undercharging, huh, huh), it is not appropriate to note that the maintenance personnel said that the new battery should be sufficient for more than 12 hours. According to the use situation and your own situation, such as long mileage during the day, just charge a little longer, the mileage of the ride is short, it will be less charged for a while, or there is a reference to grasp the charging time before going to bed.
