Electric energy router and charging pile

The embodiment of the invention discloses an electric energy router and a charging pile, a controller and a plurality of power conversion circuits are arranged in the electric energy router, and each power conversion circuit converts a first alternating current electric signal transmitted by a power grid into a first direct current electric signal so as to transmit the first direct current electric signal to a corresponding vehicle-mounted power supply for charging. The method comprises the following steps of: detecting a first direct current electric signal provided by each power conversion circuit through a controller so as to determine the current charging power; and the controller controls the power conversion circuit to convert a second direct-current electric signal provided by the corresponding vehicle-mounted power supply into a second alternating-current electric signal so as to transmit the second alternating-current electric signal to the power grid. Therefore, the electric energy can be intelligen
