HVAC Systems for Electrically-Powered Vehicles

摘要

A heating, ventilation, and air-conditioning (HVAC) system for an electrically-powered vehicle (EV) having an electric motor powered by at least one battery is described. The HVAC system may comprise a blower, a conduit configured to carry air from the blower to vents leading to a passenger cabin of the EV, and an electric heater positioned in the conduit and configured to heat the air. The HVAC system may further comprise a thermal reservoir heater positioned in the conduit and including a thermal storage component configured to heat the air without using power from the battery.
