Abstract

Extending the operational lifespan of a supercapacitor. A device, deployable in temperatures reaching or extending outside a nominal industrial temperature range, comprises a power supply, backup power supply, and thermoelectric cooler control module. The backup power supply comprises one or more supercapacitors, one or more temperature sensors, and one or more thermoelectric coolers (TECs). The control module instructs the TECs to regulate operation of removing heat from the supercapacitors based upon temperature data received from the temperature sensors. An insulated enclosure may enclose the supercapacitors, temperature sensors, TECs, and optionally the thermoelectric cooler control module to further prevent the supercapacitors from overheating. The thermoelectric cooler control module may change the rate at which the temperature of the supercapacitors is reduced in response to detecting a change in temperature difference between the external environment and the supercapacitors.
