Abstract

The present invention provides a method for charging a thermal storage device of a thermal storage heat pump system in a vehicle. The method includes comparing an actual temperature of the thermal storage device to a target temperature, and an actual charging time to an available charging time, wherein the comparison is performed by the controller. The target temperature may be based on ambient air temperature and ambient air humidity. Actual charging time is the time it takes to charge the thermal storage device to the target temperature. The available charging time is the difference between the current time and the expected driving time. When the target temperature is greater than the actual temperature and the available charging time is equal to or greater than the actual charging time, the controller may charge the thermal storage device until the actual temperature is equal to the target temperature.

Description

technical field [0001] The present invention relates to a method for storing thermal energy in a vehicle, such as a hybrid electric vehicle (HEV) or a plug-in hybrid electric vehicle (PHEV), and a system for implementing the method. Background technique [0002] Electric vehicles, such as hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), etc., typically include an electric motor that can solely propel the vehicle in pure electric vehicle (EV) or battery-consuming drive modes. The vehicle may also include an internal combustion engine (ICE) to serve as the vehicle's primary propulsion system in range-extended mode, or to operate in conjunction with an electric motor in hybrid or charge-sustaining modes. [0003] Electric motors typically receive electrical power from a power source such as an energy storage system (ESS). An ESS may include a battery pack or other rechargeable energy storage device capable of storing large amounts of thermal energy. ES...
