How long does it take to charge lithium-ion batteries for electric vehicles and how to use them correctly

Generally, the newly purchased lithium-ion battery for electric vehicles is new and has a large capacity. The charging time will be longer. It will reach more than 10 hours without changing the light. It will become faster and faster in the future, and it will be reduced to 6 hours after about 2 months. After that, it will be constant and last for about half a year, and the battery capacity will continue to decay, and it can be fully charged in 3-4 hours after 1 year. Of course, the battery should almost be replaced or maintained. The charging time for the first charge, because the battery car battery has not experienced charging and discharging when it is not used at the factory, so the normal operation of the battery must be ensured. Under normal circumstances, the charging time is about 5-6 hours, and the battery can be fully charged, and the subsequent use can be charged a little longer. After the first charge, although it is not the first charge, but the second charge is also a new car charge. At this time, you can let the battery car's battery run out, and then charge it for a long time. This charge can last 8-9 Even 10 hours, in order to let the battery car chemical reaction go through a complete cycle. The current lithium-ion battery chargers for electric vehicles are all three-stage charging, which is divided into a constant voltage phase, a constant current phase, and a trickle phase. The first two stages are important stages of charging. After the battery is fully charged, the light will turn green and enter the trickle stage. Don't unplug the battery at this time. Continue charging for 1-2 hours, which can effectively increase the battery life, but turns green. Do not exceed 8 hours afterwards. According to relevant experience, as long as the factory time of the new battery is within 15 days and it has not been used, it can be used directly without charging. If it exceeds this time, because of self-discharge problems, the user has to travel far away and can install a charger to fill it. Reused. Correct use of lithium-ion batteries for electric vehicles 1. Charge it every day. Even if your electric vehicle lithium-ion battery can be used for 2 to 3 days with a single charge, it is recommended that you charge it every day. Because the used lithium-ion battery is in a shallow cycle, charging it every day will extend the life of the lithium-ion battery of electric vehicles. 2. Charge in time because lithium-ion batteries will enter the vulcanization process after they are discharged. If they are charged in time, they can remove the less serious vulcanization. Therefore, the lithium-ion battery should be charged as soon as possible after use, and the battery power should be as full as possible. 3. Regular deep discharge of the battery Regular deep discharge is also beneficial to activate the battery, which can slightly increase the battery capacity. The general method is to fully discharge the battery periodically. 4. When the lithium-ion battery is stored for a long time without using the battery, the battery should be disconnected from the vehicle, and some power should be added to the battery at intervals to prevent self-discharge of the battery or over-discharge of the battery due to the power consumption of the protection board. In terms of charging and discharging, the current charging methods for electric vehicles are basically two household charging piles and charging pile fast charging.
