Title:
THREE ELECTRODE-CONTAINING ZINC-AIR FLOW BATTERY ENERGY STORAGE SYSTEM, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/102720
Kind Code:
A1
Abstract:
Disclosed are a three electrode-containing zinc-air flow battery energy storage system and a control method, pertaining to the technical field of flow batteries. The system comprises a PCS, in which input terminals of the PCS have one-to-one correspondence with and are connected in series to a pre-charging resistor, a fuse, and a BMS via a charging positive terminal, a negative terminal, and a first CAN bus. A pre-charging contact is installed at one side of the pre-charging resistor. A primary positive contact is connected to the pre-charging resistor in parallel at one side thereof. One side of the primary positive contact is electrically connected to a first charging and discharging module via a general positive wire. A Hall current sensor is connected to the fuse in series on one side of the negative terminal. The battery structure of the present invention is a structure having a discharging positive terminal, a charging positive terminal, and a negative terminal. The control process of the three terminals differs from that of two terminals in that an electronic switching switch is required during a charging and discharging processes, the electronic switching switch is switched to a position between the charging positive terminal and the negative terminal while performing charging, so as to disconnect the discharging positive terminal from the negative terminal, and the electronic switching switch electrically connects the discharging positive terminal and the negative terminal while performing discharging, so as to disconnect the charging positive terminal and the negative terminal.
