Input/output controller for secondary battery and vehicle

摘要

An input/output controller for a secondary battery installed in a hybrid vehicle includes a temperature sensor detecting a battery temperature of a battery, a voltage sensor detecting battery voltage of battery, and a control unit for receiving temperature detected by temperature sensor and battery voltage detected by voltage sensor and setting a limit value of electric power to be inputted to or outputted from battery. Control unit changes a change ratio of the limit value to be inputted or outputted relative to battery voltage in accordance with temperature.
