Title:
ESTIMATION DEVICE AND ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/189727
Kind Code:
A1
Abstract:
The present invention provides an estimation device and an estimation method. The present invention comprises: an input unit to which are inputted an element temperature measured for some power storage elements among a plurality of power storage elements that constitute a power storage device, and an environment temperature of the power storage device; and an estimation unit that estimates the temperature of the power storage elements on the basis of a heat balance model for the power storage elements, the heat balance model being represented using the element temperature and the environment temperature.
