Abstract
A temperature detector detects a temperature of an electricity storage unit installed in a casing. A controller estimates a temperature outside the casing on the basis of a detection temperature of the electricity storage unit detected by the temperature detector. The controller estimates an outdoor air temperature outside the casing on the basis of a change amount of detection temperature per a predetermined period detected in a state where a cooling unit is operated and a change amount of detection temperature per the predetermined period detected in a state where the cooling unit is stopped.
Claims5
An electricity storage device comprising:
- an electricity storage unit which is installed in a casing;
- a temperature detector which is installed in the casing and detects a temperature of the electricity storage unit;
- and
- a controller which estimates a temperature outside the casing based on a detected temperature of the electricity storage unit detected by the temperature detector,
- wherein the controller estimates an outdoor air temperature outside the casing based on a change amount of the detection temperature per a predetermined period detected in a state where a cooling unit is operated and a change amount of the detection temperature per the predetermined period detected in a state where the cooling unit is stopped.
