U.S. patent application 20180086177 (applicant Hanon Systems, Daejeon, South Korea):
"A method of efficiently heating a passenger cabin of a vehicle includes heating a first fluid using a fluid heater. The first fluid flows through a thermal storage element to transfer thermal energy to the thermal storage element. The heating of the first fluid and the thermal storage element occurs during a recharging of a rechargeable power source used to power the vehicle. During operation of the vehicle and following discontinuation of the recharging of the rechargeable power source, the thermal energy stored to the thermal storage element is transferred to air to be distributed to the passenger cabin of the vehicle by flowing the first fluid through a first heat exchanger in thermal communication with the air to be distributed to the passenger cabin of the vehicle, thereby extending a range of the vehicle."
