Thermal Storage Tank (TST) - Thermal energy storage system based on existing vehicle washer tank to recover heat and to extend cold operation of electrified vehicles.
The main challenge of Electric Vehicles is the short range due to limited battery capacity. This is further aggravated under low temperature, where the battery loses capacity and supplemental heating draws significant electrical energy, reducing range by up to 40%. On the other hand, excess heat produced during operation or charging is usually rejected to the environment. The Thermal Storage Tank (TST) uses the thermal mass of the existing washer tank, carried on every vehicle, as a heat storage device. The heat generated during vehicle operation is stored on-board and released during cold re-start of the vehicle, supplementing auxiliary electric heating. It may also serve as a heat sink during thermal peaks, for example in fast charging mode. Washer tank sizes are increasing due to the additional cleaning needs for driver assistance devices. In summary, while the electrical powertrain recuperates kinetic energy, the TST recuperates thermal energy.
