Analysis of the first charging method and charging time of lithium batteries for electric vehicles

The first charging method of the lithium battery of electric vehicle: 1. The charging time of the lithium battery of electric vehicle for the first time, because the battery of the battery vehicle has not been charged and discharged when it is not used at the factory, and the normal operation of the battery must be ensured. Under normal circumstances, the charging time is about 5-6 hours, so that the battery can overflow, and the subsequent use can be slightly longer. 2. After the first charge, although it is not the first charge, but the second charge is also considered 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 be maintained for 8 -9 or even 10 hours, in order to let the battery car chemical reaction go through a complete cycle. 3. When the battery car is charged for the first time, the charger may generate heat very quickly and very high. Therefore, especially in the summer, do not place the lithium battery charger on objects that are easy to heat or burn, and it is best not to put it on On the seat of the battery car, beware of a fire. 4. The electric vehicle's electricity consumption must be used up before the first charge, but it cannot be used up. When an electric car is newly purchased, the battery will not be too full, but it will not be too low, unless it is an old battery or a low-quality battery. When you use it, you should estimate the approximate distance you can travel based on the merchant’s estimate, so as not to run out of electricity or run out of electricity. When the battery power display has reached the last grid, you should consider not to ride, and prepare to charge. ◆Because the lithium batteries for electric vehicles sold in the market are fully charged, the first time for a new lithium battery to be charged should be with the charger jumping off the light, and then recharge it for 1-2 hours. The recharge time in summer can be appropriately shortened, and it is not advisable to charge for a long time after the lamp is turned off. ◆The best time to charge is: recharge after riding to about 70% power. After the summer charging turns to the green light, it can be floated for 1 to 2 hours. After the charging turns to the green light in winter, the float charging time can be extended by about 2 hours. In particularly cold places in the north, try to carry lithium batteries indoors for charging. ◆When the lithium battery is charged for the first time, the charger may generate heat very quickly and very high. Therefore, especially when charging in summer, the charger should not be placed on objects that are easy to heat or burn, and it is best not to put it on a battery car. On the seat, beware of fire.
