BACKUP POWER SUPPLY SYSTEM AND MOVING VEHICLE

Abstract

The problem to be overcome by the present disclosure is to reduce waste of an electrical storage unit. A backup power supply system (1) includes an electrical storage unit (2) and a control unit (3). The electrical storage unit (2) supplies electric power to a load (4) according to an electrical characteristic of a main power supply (5). The main power supply (5) supplies electric power to the load (4). The control unit (3) controls the supply of the electric power from the main power supply (5) and the electrical storage unit (2) to the load (4). The load (4) includes a first load (41) and a second load (42). When the electrical characteristic of the main power supply (5) is equal to or greater than a first threshold value (Vth1), the control unit (3) performs control to have both the first load (41) and the second load (42) supplied with the electric power from the main power supply (5). When the electrical characteristic of the main power supply (5) is less than the first threshold value (Vth1), the control unit (3) performs control to have the second load (42) supplied with the electric power from the main power supply (5) and have the first load (41) supplied with the electric power from the electrical storage unit (2).
