Title: POWER SOURCE DEVICE AND VEHICLE AND POWER STORAGE DEVICE PROVIDED WITH THIS POWER SOURCE DEVICE
Abstract:
[Problem] To constantly supply power to a necessary load even in a state in which a main switch is OFF, while over-charging and over-discharging of a battery are prevented. [Solution] A power source device is provided with a battery (1) comprising cells (2) that are charged by a charging mechanism (25) and supply power to a power supply terminal (22) of a load (20) to which power is supplied in a state in which a main switch (21) is ON, and supply power to a constant-conduction terminal (23) to which power is supplied in a state in which the main switch (21) is ON or OFF. In the power source device, a current-limiting circuit (3) that limits discharge current and a control switch (4) that controls the charging/discharging of the battery (1) are connected at the output side of the battery (1), and the battery (1) supplies power to the constant-conduction terminal (23) of the load (20) via the current-limiting circuit (3), and supplies power to the power supply terminal (22) of the load (20) via the control switch (4).
