Charging a battery with a 36 volt electric bike with a 48 volt charger produces the following different results:
1. The maximum current of the charger is less than 20% of the battery capacity. As long as the charging time can be controlled less than the same rated voltage for one hour, it has little effect on the battery. Otherwise, the battery is easily damaged.
2. When charging, if the battery is fully charged, the battery will be damaged because the charging voltage is higher than the battery end charging voltage.
3, the general charger charging principle: the charger generally uses four-stage charging, when the battery is low, the constant current charging mode is used, that is, charging at a constant current. At this time, the power consumed by the control circuit is relatively small compared with the charging. When the voltage reaches a certain value, it is switched to the constant voltage charging mode. As the battery voltage rises, the charging current is gradually reduced until the charging voltage is equal to the battery voltage. In this process, the consumption ratio of the control circuit is gradually increased. Therefore, there are four-stage, five-segment..., in order to reduce unnecessary consumption, in the process of constant voltage charging, constant current charging (the more the segmentation, the higher the efficiency, the more complicated the control), when When the charging voltage is equivalent to the battery voltage, it enters the so-called “turbulent flow” charge. The balance voltage at this time is generally designed to the value of the voltage drop generated by the battery internal resistance when the battery is terminated with the charging voltage (1.2 times the rated voltage of the battery). (Different batteries have different internal resistance).
