Smart battery with integrated internal thermal sensor

Abstract

A rechargeable battery system is provided. The rechargeable battery system comprises: a battery cell having a laminated housing enclosing electrolyte and electrode stacks; a thermal sensing pad embedded within the battery cell, the thermal sensing pad comprising a plurality of temperature sensors disposed at different internal positions within the battery cell, each temperature sensor encapsulated in an electrolyte-resistant material; an integrated circuit board electrically coupled with the thermal sensing pad, the integrated circuit board configured to: (a) receive sensor signals from the temperature sensors; (b) convert the sensor signals into digital temperature data; and (c) transmit the digital temperature data to a battery management system. The battery management system is configured to analyze the digital temperature data to assess internal temperature conditions of the battery cell.
