Abstract

Various embodiments provide an energy storage device. The energy storage device includes: a battery; a thermoelectric circuit provided in a proximity of an engine of a car and configured to generate avoltage based on a temperature difference; and a heating circuit configured to heat the battery based on the voltage generated by the thermoelectric circuit.

Description

technical field [0001] The invention relates to an energy storage device and a method for controlling an energy storage device. Background technique [0002] Energy storage devices such as supercapacitors, hybrid supercapacitors (HSC) or electric double layer capacitors (EDLC) generally do not work well when they are cold. Many attempts have been made to overcome the problems associated with cold energy storage devices, such as warming the devices or trying to redesign the devices so that they work despite being cold. [0003] Some of these attempts were less successful or expensive, or made the entire system heavier than they should have been. The problem of energy storage devices not working well when they are cold is evident when cars will not start in cold weather conditions. Also, when the energy storage device is cold, the internal resistance is high and the energy storage device cannot be charged well, so that the energy storage device cannot store energy efficientl...
