The voltage detection unit 153 monitors the real-time voltage of the battery pack 20 in real time, the identification unit 154 determines the current charging stage of the battery pack 20 according to the real-time voltage, and when the charging stage changes, the current output unit 155 controls the power supply body 11 to transmit the corresponding current to the battery pack 20 according to the real-time charging stage of the battery pack 20.
When the voltage detection unit 153 detects that the real-time voltage of the battery pack 20 does not reach the first preset value, the identification unit 154 identifies that the charging stage is the first charging stage, and the current output unit 155 controls the power source body 11 to output the first trickle charge current. When the voltage detection unit 153 detects that the real-time voltage of the battery pack 20 reaches the first preset value and does not reach the second preset value, the battery pack 20 enters the second charging stage, the current output unit 155 is switched to output the constant current charging current, so that the real-time voltage of the battery pack 20 rapidly rises compared with the first charging stage, and when the real-time voltage of the battery pack 20 reaches the second preset value and approaches the rated voltage, the current output unit 155 is switched to output the second trickle charging current to charge the battery pack 20 in a trickle mode until the real-time voltage of the battery pack 20 reaches the rated voltage.
