Abstract: A driver selection type rapid heating control method is provided. In an eco-vehicle, when an off signal of a hybrid electric vehicle (HEV) input pressed by a driver is received in response to detecting a heating signal while being driven in an electric vehicle mode (EV mode), the rapid heating is performed by an idling of an engine and an operation of a positive temperature coefficient (PTC) heater. When an on signal of the HEV input is detected, rapid heating is performed by a driving of an engine and the operation of the PTC heater. Thus, the rapid heating is performed with minimal fuel consumption against battery consumption under conversion into the EV mode, in particular, rapid windshield glass defrosting is performed for securing a field of view while driving by the driver selection.

Abstract: An energy accumulator system for accumulating heat from a heat source for subsequent supply to a heat demand, comprises an energy accumulator having a storage material in a heat-exchange relation with the heat source so as to store heat produced by the heat source. A controller is connected to the energy accumulator to obtain temperature data with respect to the storage material, and to the heat source so as to selectively actuate the heat source. An energy level calculator is associated with the controller to determine a storage capacity in the energy accumulator as a function of temperature data of the storage material. An operation identifier determines when to store energy in the energy accumulator as a function of the storage capacity and of condition data pertaining to the heat source. The controller actuates the energy accumulator and the heat source to store heat in the energy accumulator.
