[0016] like Figure 1 As shown, the automobile generator testing system of this embodiment includes an automobile charger, an automobile generator charging system and an automobile battery.
[0017] The car charger includes an output power module, a resistor R1, a resistor R2, a voltage detection unit, an electrolytic capacitor EC1, and a current detection unit.
