Charging and discharging control method of power distribution system, charging and discharging control method of energy storage device, and power distribution system

Abstract

The application provides a charging and discharging control method of a power distribution system, a charging and discharging control method of an energy storage device and the power distribution system. The charging and discharging control method of the power distribution system multiplexes a trigger signal pin on a parallel port to transmit a pulse control signal or a charging and discharging control signal to the connected energy storage device through a trigger signal line. When detecting that the energy storage device is connected, the power distribution system transmits an inhibition signal to the energy storage device through a communication module to avoid the energy storage device responding to the pulse control signal for charging and discharging switching by mistake, and then outputs the pulse control signal through the trigger pin to detect the position of the parallel port corresponding to the energy storage device, and after the position detection of the parallel port is completed, the energy storage device is enabled to respond to the charging and discharging control signal through an enable signal, so that the trigger signal pin in the multiplexed parallel port can control the charging and discharging of the energy storage device, thereby reducing the hardware complexity of the power distribution system for realizing the charging and discharging control of the energy storage device, and further reducing the manufacturing cost of the power distribution system.
