Boost charge: Charge according to the maximum current until the battery voltage reaches the constant voltage charging voltage. Different battery boost charging voltages refer to the battery of charging parameters. Constant voltage charging : When the battery voltage rises to a boost charging voltage, the current begins to fall and enters constant voltage charging, and the constant voltage charging time is 2hWhen the battery voltage is> 12.6V, the constant voltage charging is cancelled and the floating charging is directly charged Floating charge : After the constant voltage charging is completed, the floating charging starts, the current decreases, and the battery voltage maintains the floating charging voltage.
