IN-VEHICLE SWITCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/230636
Kind Code:
A1
Abstract:
Provided is an in-vehicle switching device which switches a plurality of batteries between a series-connection state and a parallel-connection state, wherein conducting paths through which current is allowed to flow during the series-connection state are more securely cut off. An in-vehicle switching device (1) has: a switching circuit (14); a first conducting path (11) through which current is allowed to flow in the series-connection state and through which no current flows in the parallel-connection state; a second conducting path (12) through which current is allowed to flow in the parallel-connection state and through which no current flows in the series-connection state; a third conducting path (13) that during the series-connection state constitutes a path between the negative electrode of a first battery (10A) and the positive electrode of a second battery (10B), and during the parallel-connection state constitutes a path either between both positive electrodes or between both negative electrodes of the first battery (10A) and the second battery (10B); and a fuse section (14D) that is provided in the first conducting path (11) and that on the basis of an external signal carries out an operation of cutting off the first conducting path (11).
