The invention relates to a charging and discharging control method of a charging pile and a charging and discharging system. The method includes: detecting the charging demand of an electric vehicle; if the electric vehicle has a charging demand, detecting the state of charge of an energy storage power supply; If it is greater than the set power threshold, the energy storage power supply will output power to the electric vehicle to charge the electric vehicle; if the power state of the energy storage power supply is not greater than the set power threshold, the power grid will output the power to the electric vehicle to charge the electric vehicle; If the electric vehicle has no charging demand, the electric energy flow between the power grid and the energy storage power source is controlled accordingly according to whether the power grid is in the peak power period. In the present invention, when the electric vehicle needs to be charged, the energy storage power source is preferentially used to charge the electric vehicle. Only when the power of the energy storage power source is insufficient, the electric vehicle is charged by the power grid, and the electric vehicle charging demand is guaranteed. Under the circumstance, the utilization rate of energy storage power is effectively improved.

The embodiment of the invention discloses a switching method of a charging device, a device and related equipment, wherein the method includes that a mobile terminal detects signal intensity of a first charging device and sends a charging device replacing request to a charging server when the signal intensity is lower than the intensity threshold value, wherein the charging device replacing request includes battery state information of the mobile terminal; thus when the charging server looks for a second charging device matched with the battery state information, the device information of the second charging device is sent to the mobile terminal; the mobile terminal sets up charging connection with the second charging device according to the device information. Through the embodiment of the invention, the mobile terminal can determine if the charging device is replaced according to the signal intensity corresponding to the device for charging at present, and automatically charge when the matched charging device is found; thus the charging demand of the mobile terminal is guaranteed, and the wireless charging efficiency is improved.

The invention relates to a method for distributing charging power of a trolleybus. For a certain charging network segment, the number of trolley buses in the charging network segment is detected in real time, and the required charging power of each trolleybus is obtained; the actual charging power assigned to each trolleybus is then calculated. The method calculates the actual allocated power based on the ratio of the required charging power of each trolleybus to the total required charging power. The greater the required charging power is, the greater the actual allocated charging power is, meeting the needs of charging for each trolleybus. If the number of trolleybuses on the charging network segment changes, the number of trolleybuses in the network segment is re-acquired by the distribution method, and the required charging power of each trolleybus is required. Then, according to the allocation strategy, the power distribution is performed to ensure that the charging power of eachtrolleybus meets the demand, the power supply system is stabilized, and the trolleybus is in normal operation.
