Title:
BATTERY SWITCHING CIRCUIT, BATTERY SYSTEM, AND METHOD FOR CONTROLLING BATTERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/176940
Kind Code:
A1
Abstract:
This battery switching circuit comprises a plurality of switch units configured to be connectable to a plurality of battery cells. Each switch unit comprises: a first anode electrode and a second anode electrode; an anode line connecting the first anode electrode with the second anode electrode; a first cathode electrode and a second cathode electrode; and a cathode line connecting the first cathode electrode with the second cathode electrode. The anode line comprises a plurality of cell anode electrodes and a plurality of anode switching circuits alternately connected in a direction from the first anode electrode to the second anode electrode. The cathode line comprises a plurality of cell cathode electrodes and a plurality of cathode switching circuits alternately connected in a direction from the first cathode electrode to the second cathode electrode. The second anode electrode is connected to the anode switching circuit closest to the second anode electrode among the anode switching circuits. The second cathode electrode is connected to the cathode switching circuit closest to the second cathode electrode among the cathode switching circuits.
