The utility model relates to an electric energy regulating and distributing device. The device is characterized in that a three-way current acquisition circuit, a three-way voltage acquisition circuit and a two-way electronic switch driving circuit are connected to an ECU. Through one power input and two power outputs, electric equipment and a storage battery of an electric vehicle can be simultaneously charged, energy balance of three ways of power sources is achieved, under the condition that it is guaranteed that enough power output is reserved for the electric equipment of the vehicle, and the surplus power output of a battery charger is used for charging the storage battery.
