How to charge an electric car battery? Adhere to the four-step maintenance is the key

my country is the kingdom of electric vehicle processing, and the popularization of electric vehicle battery maintenance knowledge should be widely publicized. 1. Protect the charger. There are instructions on protecting the charger in the general operating instructions. Many users don't have the habit of reading the manual, and often think of looking for the manual after the problem. It is often too late, so it is very necessary to read the manual first. In order to reduce costs, the current chargers are basically not designed with high vibration resistance. In this way, the chargers are generally not placed in the trunk and basket of the electric bicycle. Under special circumstances, you must move the charger, and pack the charger with foam to guard against vibrations. After many chargers are vibrated, their internal potentiometers will drift, causing the entire parameters to drift, resulting in abnormal charging status. Another thing to pay attention to is to keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the charging state. This will damage the battery. Therefore, it is very important to protect the charger. 2. Charge in time. After the electric vehicle battery is discharged, the vulcanization process begins. Starting at 12 hours, the general charger is powerless to these coarse crystals, which will gradually reduce the battery capacity and shorten the battery life. Therefore, in addition to daily charging, we should also pay attention to charging as soon as possible after use, so that the battery power is as full as possible. 3. Do not change the charger casually, and do not remove the speed limit of the controller. The chargers of various manufacturers generally have individual requirements. Don't change the charger at will when you are not sure. If the continuation mileage requirements are relatively long, and multiple chargers must be equipped for remote charging, the chargers that are supplemented during the daytime should be supplemented with additional chargers, and the original chargers should be used at night. Removing the speed limit of the controller, although it can increase the speed of some cars, in addition to reducing the safety of the car, it will also reduce the service life of the electric vehicle battery. 4. Charge every day. Even if your continuation capacity is not long, you can use it for 2 to 3 days with a single charge, but it is recommended that you charge it every day, so that the battery is in a shallow cycle state, and the life of the electric vehicle battery will be extended. Some early mobile phone users think that it is best to charge the battery after it is basically used up. This view is incorrect. After the indicator light changes to indicate overflow, the battery charge may be 97% to 99%. Although only 1% to 3% of the power is under-charged, the impact on the continuation ability is almost negligible, but under-charge accumulation will also be formed, so after the battery overflows and the lamp is changed to the lamp, it is still possible to continue to float as much as possible, which is also useful for suppressing battery vulcanization beneficial. Comment: The maintenance of electric vehicle batteries is closely related to the correct use of chargers. As one of the four core components of electric vehicles, electric vehicle batteries are undoubtedly determined by their service life.
