There are many charger internal circuits, input and output lines aging, resulting, sometimes can be filled, sometimes cannot flush. It seriously affects the battery, or the circuit failure in the charging process, causing the drum to fill. If this is the case, please replace the high quality charger of cheap electric bike and use it again.
In general, the charger is configured according to the battery size of the electric vehicle, that is, the current and voltage. Under normal circumstances electric vehicle, four-wheel electric vehicle, electric sightseeing car electric patrol car is 18 v or 72 v are all have certain specification. But the unit of capacity of electric vehicle battery is not necessarily the same. Therefore, it is recommended that you use the matching electric car charger. But the unit of capacity of electric vehicle battery is not necessarily the same. Therefore, it is recommended that you use the matching electric car charger.
Of course, we know that battery failure is related to the charger voltage, not to the current. The charger does not convert for a long time or the charger voltage is too high to cause the battery to lose water, battery drum and so on.
The effect of the current on the battery is the speed and speed of charging the battery. But it will destroy the battery of the electric car. So the electric car charger is not a general purpose, but it is better not to use it.
