NOVELTY - An electric vehicle has a heater (111) and a fan (112) thermally coupled to the cab. The heater has an independent fuse to prevent a heater problem from shutting down the vehicle. Preferably, the heater has at least one heating element for converting electricity into heat through Joule heating. The heating element comprises an 80 percent nickel, 20 percent chromium wire, ribbon or strip, and a positive thermal coefficient of resistance. A solar cell (106) powers the heater and fan or recharges the internal battery (104).    USE - Electric vehicle. Can also be used as an electric car or as electrical truck for moving up to 1600 pounds of cargo during off-road use and which is ideal for corporate campuses, warehouses, universities, factories, municipal operations and around the ranch or farm.    ADVANTAGE - The electric heater provides a highly efficient warming system for vehicle occupants, since such system can be programmed to come on whenever the user wants, while the electric heater passes their warmth. The system can also preheat the cabin to normal operating temperature, de-mist and defrost the windows and preheat the car interior, all with the engine switched off. The heater can be turned on remotely in cold environments to avoid scraping ice and struggling with steamed up windows. The timer on the dashboard can be used to program when the user wants the heater to start, so that, by the time the user drives off, the windscreens and windows are thawed, the temperature inside the vehicle is nice and warm, and the engine is warmed up and ready to go. The system also enables the user to keep the temperature constant even when the electric hub wheel motor or engine is off due to traffic jam. The system enables driving in winter to be safer by preventing windows from steaming up and providing excellent all-round visibility. The heater can be retrofitted to an existing gas-powered vehicle so as to reduce fuel consumption and permit smooth engine start without the usual coughs and sputters and excessive exhaust fumes while also saving time, trouble and money. The fuse trips to shut down the heater when it draws too much power, ensuring protection of the heater and the vehicle.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating an electric vehicle.
