Abstract
An ultracapacitor energy storage cell pack includes an ultracapacitor assembly having a plurality of series connected ultracapacitors and balancing resistors, each balancing resistor connected in parallel with each ultracapacitor to automatically balance each ultracapacitor over time, thereby automatically over time discharging the ultracapacitors of the ultracapacitor assembly; an enclosure to enclose and protect the ultracapacitor assembly; a controller for the ultracapacitor assembly; and one or more temperature sensors to monitor temperature of the ultracapacitor assembly and coupled to the controller.
