Battery charging time of second-hand battery car

1. The charger should be matched: if the charger or battery is replaced, it is best to ask professional maintenance personnel to recommend it. Don't pay too much attention to those data, because the general charger is set, but the battery is a dynamic life process. Strictly speaking, there are not enough chargers in the market to ensure the charging quality. However, a good charger will definitely have a good charging effect on the battery. It is estimated that the market price of Nanjing market should be above 75 yuan to be considered as a better charger (to be verified, hehe).

2. "Diligent charging and shallow charging" refers to charging after each use, and try not to charge once with undervoltage (this should belong to the use method). It's full every time. There's no way to fill it. Taking practicality as the standard, things should not be greasy!

3. Generally speaking, the complete reference is: about 1 hour after the charger turns on the light, preferably no more than 2 hours. According to the service life of the battery, the charger is generally designed to be fully charged in 8 ~ 10 hours (referring to the situation that the battery discharges close to undervoltage after a long ride). At present, the battery on the market will automatically stop charging after 8 hours (there is a danger of insufficient charging, hehe). Note that some maintenance personnel say that it is not appropriate for a new battery to be fully charged for more than 12 hours. According to the use situation and your own situation, for example, if the mileage is long during the day, charge it for a while, if the mileage is short, charge it for a while, or have a reference to master the charging time before going to bed, so as not to get up in the middle of the night accurately, hehe.

4. According to the new theory of the international battery industry, it is best to charge and discharge the battery every 7~ 15 times, which is beneficial to improve the capacity and prolong the battery life. I suggest you understand this method, because it will have bad consequences, hehe. If you are a professional or have a special hobby, you can try it: the way to do everything is relatively simple, that is, riding a car until the first sign of power failure. General electric bicycles have undervoltage protection. For an electric bicycle with a nominal voltage of 36V, the undervoltage protection voltage of most controllers is around 33V. If the battery voltage will slowly restore power supply after the first power failure, do not use the electricity in the battery at this time, otherwise the battery will be over-discharged, which will seriously affect the battery life. Fully charged is fully charged, which is easier.

There are too many factors that affect the charging effect and life of the battery, such as temperature. And the key is the use of electric vehicles. It seems that many instructions for electric vehicles are jokes, such as "It is best not to use electricity when going uphill against the wind" and "Don't bring people" ... In fact, everyone should also pay attention to the current electric vehicle technology, and the final effect provided by the battery should be based on assistance. If you start using it forcibly and bring people, I am afraid that the power consumption or damage to the battery is not only 1 time. If it is convenient, I suggest you give more help.
