[0030] The electric power system includes a secondary battery 501 as a power source, a motor generator 508 controlled to supply power through an inverter 507 , and a battery controller 100 that monitors the state of the secondary battery 501 and the like. In addition, there are electric loads 512 such as lamps and heaters that use the secondary battery 501 as a power source.
[0031] The electric motor 508 is coupled with an unillustrated wheel to drive the wheel.
[0032] The inverter 507 converts the DC power of the secondary battery 501 into AC power to drive the electric motor 508 . Inverter 507 converts AC power generated by motor generator 508 into DC power, and inputs it to secondary battery 501 .
[0033] A secondary battery (battery power supply) 501 serving as an on-vehicle power supply is a rechargeable battery such as a lead battery, a lithium secondary battery, a nickel hydrogen battery, or an electric double layer capacitor. The secondary battery 501 is connect...
