WIPO Patent Application WO/2024/095672
Kind Code:
A1
Abstract:
[Problem] To provide a battery pack system, a battery module, an end module, and a paralleling module with which the degree of commonalization can be enhanced. [Solution] The present invention comprises: a battery column 3 in which a plurality of battery modules 2 are connected in a line, and which has a first end 31 and a second end 32; and an end module 4 which is connected to the second end 32 of the battery column 3. Each of the battery modules 2 has a first positive terminal Tp1, a first negative terminal Tm1, a second positive terminal Tp2, a second negative terminal Tm2, a positive-side path 21, and a negative-side path 22. Between adjacent ones of the battery modules 2, the first positive terminal Tp1 of one of the battery modules and the second positive terminal Tp2 of the other battery module are electrically connected, and the first negative terminal Tm1 of the one of the battery modules and the second negative terminal Tm2 of the other battery module are electrically connected. At least one of the positive-side path 21 and the negative-side path 22 includes a power storage part B1 and switching elements SW1, SW2 that switch the connection state of the power storage part B1. A third negative terminal Tm3 and a third positive terminal Tp3 of the end module 4 are electrically conductive to each other.
