POWER SUPPLY SYSTEM

摘要

A power supply system comprises a first battery, a second battery, an output electric circuit, a first switching element, a second switching element, and a third switching element. The output electric circuit includes a first electric circuit and a second electric circuit. The second electric circuit has a potential lower than a potential of the first electric circuit. The first, second and third switching elements are provided in series with each other from the first electric circuit toward the second electric circuit. The first battery is provided in parallel with the second switching element. The second battery is provided in parallel with a series connection between the second switching element and the third switching element.
