POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/048020
Kind Code:
A1
Abstract:
The present invention provides a power supply system capable of rapid arc extinguishing when a series arc discharge or a parallel arc discharge has occurred at a part more on a power storage module side than a power conversion device. The present invention has a power storage module, a power conversion device, a bidirectional converter unit, and an arc discharge detection unit. The power storage module has a secondary battery and is connected to the power conversion device through the bidirectional converter unit. The arc discharge detection unit detects an arc discharge inside the power conversion device, or at a part more on the power storage module side than the power conversion device. When the arc discharge detection unit has detected an arc discharge, the arc discharge detection unit carries out an arc blocking operation to block power conduction between the power conversion device and the secondary battery.
