Solar Assisted Light Electric Vehicle Electric vehicles are greatly encouraged because of the policies for the reduction of pollution and greenhouse gas emissions. The pleasant and satisfying environment is a mandatory in-vehicle cabin both in electric vehicles and internal combustion engine vehicles. To avoid the heat from the engine, and innovating air conditioning system design, the coolant in electric vehicles must be implemented. The issue is solved by studying it broadly. The use of an electric compressor instead of the mechanical compressor is the most natural solution for cooling; on the other hand, a positive temperature coefficient (PTC) heater is used to give a heating alternative to the engine coolant heater core.
