Document Type and Number:
WIPO Patent Application WO/2024/043023
Kind Code:
A1
Abstract:
The object of the present invention is to achieve redundancy of a power supply function by a simple configuration, to ensure operational continuity in case of failure. A power grid (1) comprises: a first power supply path (20-1) that is connected to a main engine-driving power source (100-0) of a vehicle via a power conversion device (101) and to loads (40-1, 41, 42-1); and a second power supply path (20-2) that is connected to a power source (100-2) different from the main engine-driving power source (100-0), to loads (40-2, 41, 42-2), and to the first power supply path (20-1) via a switch SW0. The switch SW0 is closed when the first power supply path (20-1) and the second power supply path (20-2) are normal, and is opened when the first power supply path (20-1) or the second power supply path (20-2) is abnormal.
