Kind Code:
A1
Abstract:
In a power supply control device (11), when a bypass switch (25) is OFF when the connection of a battery (10) is normal, current flows through a first switching circuit (21) and a diode (24) in this order. When the connection of the battery (10) is normal, a second switching circuit (22) switches the bypass switch (25) from OFF to ON when the output voltage of the battery (10) becomes less than a reference voltage.
