An automobile charger, a charging method and a medium are provided. The charger includes a MCU, a switching power supply circuit, a first and second charging circuits, a battery voltage detection circuit, a charging current detection circuit, a constant-current driving control circuit, a constant-voltage driving control circuit and a switch driving control circuit. The charger is provided with the first and second charging circuits, which can realize three charging modes on the battery. The real-time voltage signal and the real-time current signal are collected with the battery voltage detection circuit and the charging current detection circuit, and through feedback of the real-time voltage signal and the real-time current signal, the MCU is configured to output PWM signals with different duty ratios to the constant-current driving control circuit and the constant-voltage driving control circuit, so as to realize output of different voltage values and current values of the switching power supply.
