Abstract
A power source control system for a vehicle is provided, which includes a traction motor, the system including a first battery that is a bipolar battery and is to be used as a power source for the traction motor; a second battery that is a bipolar battery different from the first battery; a mirror current generator circuit configured to generate a mirror current based on a current flowing through the first battery; a mirror current supply source circuit configured to cause the mirror current to flow through the second battery; and a diagnostic circuit configured to perform degradation diagnosis on the second battery on a basis of at least one of a voltage or a temperature of the second battery.

A power source control system for a vehicle, the vehicle comprising a traction motor, the power source control system comprising:
- a first battery that is a bipolar battery and is to be used as a power source for the traction motor;
- a second battery that is a bipolar battery different from the first battery;
- a mirror current generator configured to generate a mirror current based on a current flowing through the first battery;
- a mirror current supply source configured to cause the mirror current to flow through the second battery;
- and
- a diagnostic unit configured to perform degradation diagnosis on the second battery on a basis of at least one of a voltage or a temperature of the second battery.
