POWER SYSTEM AND VEHICLE HAVING SAME, METHOD FOR CONTROLLING TEMPERATURE RISE OF POWER STORAGE DEVICE, AND COMPUTER-READABLE RECORDING MEDIUM ON WHICH PROGRAM FOR ALLOWING COMPUTER TO EXECUTE TEMPERATURE RISE CONTROL OF POWER STORAGE DEVICE IS RECORDED

摘要

A converter ECU (2) controls a converter (8) to transmit an electric power between a power storage device (6) and a power storage unit (7) through a main positive bus line (MPL) and a main negative bus line (MNL) during temperature rise control of the power storage device (6). Specifically, converter ECU (2) sets a target voltage of the converter (8) to a second voltage value lower than a first voltage value when a voltage value (Vh) reaches the first voltage value, and sets the target voltage of the converter (8) to the first voltage value when the voltage value (Vh) reaches the second voltage value.
