Title:
BATTERY SAFETY EVALUATION DEVICE, BATTERY CONTROL DEVICE, BATTERY SAFETY EVALUATION METHOD, PROGRAM, CONTROL CIRCUIT, AND POWER STORAGE SYSTEM
Document Type and Number:
Japanese Patent JP2019220471
Kind Code:
A
Abstract:
To evaluate the safety of a secondary battery non-destructively.SOLUTION: A battery safety evaluation device according to an embodiment of the present invention includes a safety index calculation unit. The safety index calculation unit calculates the temperature of a first battery that is a secondary battery to be evaluated at an external temperature on the basis of the calorific value of the first battery, the specific heat of the first battery, a heat transfer coefficient between the first battery and the outside of the first battery, and the external temperature. Further, the safety index calculation unit calculates a safety index of the first battery on the basis of the calculated temperature of the first battery.SELECTED DRAWING: Figure 1
