Abstract:
Provided is a power supply system (100) comprising: a first system (ES1) having a first power supply (10, 12) and a first energization path (LA1); a second system (ES2) having a second power supply (16) and a second energization path (LA2); and inter-system switches (SW1, SW2), wherein the first power supply outputs a power supply voltage, the second power supply includes a storage battery (16) that can be charged by the power supply voltage, and includes a switching control unit (40) which switches the closed/open state of the inter-system switch, and a charging/discharging unit (21, 22, 23, 24, 27) which is provided between the second power supply and the connection point with the connection path in the second energization path to charge the storage battery by means of the power supply voltage and to discharge the storage battery in response to the discharge request after the charging is completed, and the charging/discharging unit is configured such that when the inter-system switch is closed and an overvoltage occurs in any system, charging of the storage battery is started before the inter-system switch is switched from the closed state to the open state by the switching control unit.
