Title:
VEHICLE POWER SUPPLY MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/218652
Kind Code:
A1
Abstract:
A vehicle power supply management system (1) according to the present disclosure comprises main contactors (4, 5), a pre-charge contactor (7) and a pre-charge resistor (8), capacitors (14, 24), and a control device (30). The control device (30) performs a pre-charge control and a main control. The pre-charge control increases the voltages of the capacitors (14, 24) by connecting the pre-charge contactor (7) in response to a ready request. The main control connects the main contactors (4, 5) and disconnects the pre-charge contactor (7) after the voltages of the capacitors (14, 24) reach the voltage of a battery (2). The control device (30) maintains the connection state of the pre-charge contactor (7) until the voltages of the capacitors (14, 24) reach the voltage of the battery (2) even when the ready request is inactivated while performing the pre-charge control.
