BLOCKING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/190401
Kind Code:
A1
Abstract:
Provided is a blocking control device with which it is possible to anticipate a plurality of overcurrent states and to perform a control suited to each of the overcurrent states. This blocking control device (30) controls a blocking unit (34) in an onboard system (10) that has: a power storage unit (91); an electric power path (31) between the power storage unit (91) and a load (94); and the blocking unit (34), which switches between a blocking state for blocking electric power from being supplied from the power-storage-unit (91) side to the load (94) side in the electric power path (31) and a cancellation state in which the blocking state is cancelled. In the onboard system (10), the blocking unit (34) has a first blocking unit (34A) and a second blocking unit (34B), and the second blocking unit (34B) enters the blocking state when a first overcurrent state is generated in the electric power path (31) while the first blocking unit (34A) is in the cancellation state. The blocking control device (30) comprises a control device (20) that instructs the first blocking unit (34A) to switch to the blocking state when the electric power path (31) is in a second overcurrent state.
