  • Patent number: 11002794
    Abstract: A control apparatus of a power supply system including a battery, a battery sensor to detect a state quantity of the battery, and a generator to generate a power for the battery includes a controller. The controller executes normal charging control to control battery charging based on a detection result from the battery sensor, by controlling an operation of the generator. The controller executes failsafe control to prioritize battery charging regardless of the detection result from the battery sensor, if the battery sensor is determined to be operating abnormally. The controller executes full charging control to charge the battery until the battery is fully charged, when the failsafe control ends. The controller executes the normal charging control after a state-of-charge of the battery used in the normal charging control is set to a value corresponding to a state where the battery is fully charged, when the full charging control ends.
