The invention discloses a charging method of a lead-acid storage battery, a terminal and a storage medium, and the charging method comprises the steps: determining the error calibration voltage of a vehicle component through the output voltage of a charging and discharging unit during working and the target voltage of the lead-acid storage battery during working of the charging and discharging unit, and enabling the target voltage to be measured by an electronic control unit; determining the current actual voltage of the lead-acid storage battery by using the target voltage and the error calibration voltage; determining the current electric quantity of the lead-acid storage battery from the voltage-current-electric quantity characteristic curve by utilizing the current actual voltage and the current current of the lead-acid storage battery; and according to the current electric quantity, whether the power battery of the vehicle carries out charging operation on the lead-acid storage battery is judged. According to the scheme, the electric quantity of the lead-acid storage battery can be more accurately determined, whether the power battery is used for charging the lead-acid storage battery or not is judged, and the charging reasonability is improved.
