<P>PROBLEM TO BE SOLVED: To provide a controller capable of detecting a voltage and load on a battery pack side or a voltage on a charge/discharge apparatus side without correcting variations in voltage detection. Ž<P>SOLUTION: A power supply part of a hybrid vehicle includes: the battery pack 100; an inverter 102 as the load or the charge/discharge apparatus; and a controller 101 that detects the voltage of the battery pack 100 and the voltage of the inverter 102, and the battery pack 100 and the inverter 102 are connected via relays 1 to 3. In the control part 101, variation correction in the detection is eliminated since a voltage sensor 103 for detecting the voltage on the battery pack 100 side and the inverter 102 side is used in common, and the voltage at different positions can be detected by the voltage sensor having the same characteristics.
