Abstract
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.
Claims8
An input/output controller for a secondary battery, comprising:
- a temperature detecting unit detecting a battery temperature of said secondary battery;
- a voltage detecting unit detecting battery voltage of said secondary battery;
- and
- a setting unit receiving said battery temperature detected by said temperature detecting unit and said battery voltage detected by said voltage detecting unit and setting a limit value of electrical power to be inputted to or outputted from the secondary battery, said setting unit changing a change ratio of said limit value relative to said battery voltage in accordance with said battery temperature.
A vehicle, comprising:
- a secondary battery;
- and
- an input/output controller for controlling an input and an output of said secondary battery, including
- a temperature detecting unit detecting a battery temperature of said secondary battery;
- a voltage detecting unit detecting battery voltage of said secondary battery;
- and
- a setting unit receiving said battery temperature detected by said temperature detecting unit and said battery voltage detected by said voltage detecting unit and setting a limit value of electrical power to be inputted to or outputted from the secondary battery, said setting unit changing a change ratio of said limit value relative to said battery voltage in accordance with said battery temperature.
