Charging Method Of Electric Vehicle
Under normal circumstances, electric vehicles (not often carrying people and not climbing all day long) are generally best charged when they are driven to 60% - 70% of the longest mileage in the manual, which can not only avoid the early capacity loss of the battery, but also avoid overdischarge.
2. If you often take people and climb slopes, it is recommended to drive to 50% of the maximum mileage in the manual to charge.
3. If you don't drive very often and don't drive 60% - 70% of the longest mileage in a week, it is recommended to charge it once.
4. If you go out or don't drive for a long time, it is recommended to charge once a month.
5. In any case, the charging time of the battery should not exceed 8 hours, especially in the case mentioned in points 3 and 4, not more than 5 hours.
Generally, the production date of electric vehicle batteries will not exceed one month (the production date must be clearly seen when buying). The new batteries have been fully charged when they leave the factory. Except for the loss of battery power caused by the transportation process and storage time, the new batteries will not be charged after loading, unless the production date has exceeded one month and they need to be fully charged. The new battery shall be used up three times before charging (charging is required after the under voltage prompt), and the charging time shall reach 12 hours. After three times, you can follow the following charging method.
It is right to use and charge the battery frequently. Basically, it means charging after riding every day. However, there is a problem here. If your battery can run for 30 kilometers, charge it after running for 5 kilometers or 10 kilometers, it may not be good for the battery. When the battery is fully charged, there will definitely be gas overflow, and this gas is generated by the decomposition of water in the electrolyte, so water loss will occur, Frequent such charging will increase the number of water loss of the battery, and the battery will soon enter the expiration period.
Therefore, the best way is to fully charge the electric vehicle if you don't ride it the next day. However, after you ride for 5km or 10km, the next day's journey is still enough. It's better to wait until the next day to recharge it. In this way, the water loss of the battery will be reduced and the battery life will be extended.
In addition, when some batteries can run for about 30 kilometers, but they ride for about 7 or 8 kilometers every day, it is better not to wait until the third or fourth day when the battery is fully charged. It is better to charge the battery when the remaining half of the battery is less than half. Because the battery is stored when the battery is insufficient, it is easy to produce vulcanization.
In addition, it is best to ride the battery once every month, that is, ride the battery to under voltage, deep discharge once, and then charge the battery. This can also extend the service life of the battery.
Another point is that when charging, first plug in the battery terminal and then connect 220V mains. At the end of charging, first unplug the 220V mains power, then unplug the battery end. When the charger turns green, it can be recharged for about one to two hours. The battery will be fully charged, and cannot be recharged overnight. This will cause overcharge, which will cause serious damage to the battery. Remember remember!
In addition, the electric vehicle battery is often used, and the battery life will be relatively long. That is to say, the battery is not afraid of you using it every day, but it is afraid of you not using it for a long time. Therefore, it is very important to master the charging method of electric vehicle battery for battery life.
