BATTERY MONITORING DEVICE, POWER STORAGE SYSTEM, AND CONTROL SYSTEM

摘要

A control unit (240) of a battery monitoring device (200), said control unit calculating the amount of heat generated inside a battery (110) on the basis of information about the current which flows out of or flows into the battery (110). Furthermore, the control unit (240) calculates the amount of heat radiated from the surface of the battery (110), said amount being calculated on the basis of temperature information about at least one from among the surface of the battery (110), and a substance in the vicinity of the battery (110). In addition, the control unit (240) calculates the temperature inside the battery (110) on the basis of information about the amount of heat generated, and information about the amount of heat radiated.
