Abstract
A charging system includes: an input voltage supply circuit; a control circuit coupled to the input voltage supply circuit, configured to control the input voltage supply circuit to generate an input voltage according to a battery voltage of a target battery; and a charging circuit, coupled to the control circuit, configured to receive the input voltage and to provide a charging current to charge the target battery. The input voltage is generated according to a function that takes the battery voltage as a parameter. The input voltage is positively correlated with the battery voltage, and is greater than the battery voltage.
