Abstract: A charging and discharging method for energy storage, relating to the technical field of new energy. The method comprises the following steps: (1) setting up a hardware system; (2) carrying out initialization detection to ensure that each hardware device is in a normal state; (3) setting up a software system; and (4) during standby or working, a controller reading battery parameters of each measurement and control unit in turn and comparing set data to make corresponding actions. The charging and discharging method for energy storage has the advantages of simple and convenient wiring, low cost, and easy maintenance.

Abstract: A measurement and control module for intelligent charging and discharging, and a charging and discharging system using the module, wherein the measurement and control module comprises measurement and control units, each measurement and control unit is in circuit connection with an automatic switching element and a battery to be measured, the automatic switching element is arranged on a main connecting wire of the battery and is connected to a power supply, and a bypass circuit that bypasses the corresponding battery to be measured is connected between the automatic switching element and the main connecting wire. The present invention aims to provide a measurement and control module for intelligent charging and discharging that has a compact and ingenious structure, is easy to use and has good effects, and a charging and discharging system using the module. The present invention is applied to new energy.
