Resumen
Researches carried about electric vehicles are focused on extending life of the battery today. Development of higher-range batteries is as essential as efficient use of current battery energy technology. EPT System, that has average efficiency of 85%, produces waste heat up to 15% of its nominal power. The current heat pump systems, which use the waste heat, are very expensive and have complicated structures. In addition, the energy is consumed about 50% of heat transfer with this way. With the newly developed and patent applied system, the average temperature of the waste heat of the engine is raised to the temperature of engine efficiently operating In addition, the energy could be used for heating purposes without additional energy consumption. Newly developed heating system can heat with high efficiency using heat pump and stored electrical energy from heat through braking energy without any extra energy consumption.
