Document Type and Number:
WIPO Patent Application WO/2020/202810
Kind Code:
A1
Abstract:
The present invention provides a high reliability secondary cell system in which a power supply is multiplexed without using a lead storage battery. This secondary cell system 10 has two or more battery groups comprising a plurality of cells 21 connected in series, each of the battery groups 11, 12, 13 is connected in parallel. Disposed in each battery group 11, 12, 13 are open/close switches 31a, 31b, 32a, 32b, 33a, 33b that disconnect the battery group from a circuit of the secondary cell system 10. This secondary cell system 10 can comprise an active balancer 14 connected in parallel with the battery groups 11, 12, 13.
