VEHICLE POWER CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/071145
Kind Code:
A1
Abstract:
When a low-voltage battery (23) has become exhausted, power necessary for starting is supplied to the vehicle side from a simple power source (25) connected to an ACC socket (24). The power of the simple power source (25) is supplied to respective power terminals (22c, 22d) of a DC/DC converter (22) or other loads (31, 32, 33), and is used in order to start the DC/DC converter (22). After the DC/DC converter (22) is started, power on a high-voltage battery (21) side is stepped down and supplied to the low-voltage battery (23) side, and the power supply route to the DC/DC converter (22) or other loads is switched. Switching is performed between a normal mode and an emergency start mode by using a mode switch (26) or a relay.
