The design of electric vehicles and energy storage system meets the needs of saving energy and reducing production costs during the battery production process by balancing the total loop power to make the utilization of battery power more efficient.​

  • On the basis of the original charging and discharging system, the whole system sets the server side to control all the situations. The server side and charging and discharging system are communicating through the network.

  • The server side monitors the power status of each charging and discharging system in real time and controls the controlled machine to perform power equalization to change the charging or discharging power of the channel in real time, so that the total charging and discharging power of the entire system tends to zero.

  • The server has a certain delay in the control of power, preventing the power from constantly shaking, and the delay is about 10 - 20 seconds.

  • The server and charging and discharging system can be deployed in the same computer or different computers in the same LAN.

  •  The energy of the whole system has two-way flow and can automatically adjust the energy direction. That is, when charging, the energy can flow from the three-phase grid to the battery pack, while discharging, the energy is fed back from the battery pack to the three-phase grid.

  • The status of each channel of the system, including voltage, current, and working status etc., will be sent to the server in real time.

  • One certain or more channels can be set as the "equalization channel". After being set as the equalization channel, it will accept the control of the server and automatically perform the charging and discharging actions. After the channel receives the stop operation, it will exit the equalization mode.

  • The equalization channel will always run "working condition simulation" working step. As working condition of working steps is adjusting to charging and discharging in real time, the channel will start working condition of working steps and enter operation status when the equalization channel is set. At this time, the equipment battery should be connected well.

  • The charging and discharging system discovers the server at startup. After the connection is successful, the connection information is cached in the system to provide the next use and free of configuration.
