Abstract
A temperature of a power device to which a power storage device is attached is estimated on the basis of a temperature detected by a temperature detector provided in a power storage device detachably held in the power device.
Claims18
A temperature estimation device comprising:
- an estimator configured to estimate a temperature of a power device to which a power storage device is attached on the basis of a power storage device temperature that is a temperature detected by a temperature detector provided in the power storage device detachably held in the power device,
- wherein the power device includes a housing having an accommodation unit configured to accommodate at least a part of the power storage device, and
- the estimator estimates an internal temperature inside of the housing on the basis of the power storage device temperature detected by the temperature detector,
- wherein the housing includes a plurality of accommodation units configured to respectively accommodate power storage devices, and
- the estimator estimates the internal temperature on the basis of the temperature detected by the temperature detector provided in the power storage device that is electrically operating among the power storage devices accommodated in the plurality of accommodation units, and
- wherein, when a plurality of power storage devices that are electrically operating are present, the estimator estimates the internal temperature on the basis of a plurality of power storage device temperatures detected by temperature detectors provided in the plurality of power storage devices.
