Problems solved by technology

Although the existing chargers are all equipped with overcharge protection, they still have the following disadvantages: (1) the quality is uneven, the service life is not guaranteed, and after a period of use, the overcharge protection has the risk of failure; (2) ) When the overcharge protection is effective, the internal components of the charger are still in the standby state and continue to consume power. At the same time, the circuit with the rechargeable battery is also in a conductive state. Long service life and potential safety hazards
In addition, there is currently no system that can cycle charge the rechargeable battery, so that after a period of idle time, the rechargeable battery may be damaged due to excessive discharge or the battery power is insufficient when it needs to be used.
