In the publicly funded GaTE project (integrated thermal management in electric vehicles), Bosch, Mahle and other companies developed the basis for optimized thermal management.
By applying comprehensive thermal management, Bosch has successfully increased the range of e-vehicles by up to 25% in wintry city traffic without sacrificing any comfort. This is made possible by a design that combines a heat pump with innovative coolant pumps and valves. The system collects heat and cold where they occur and transports them to where they are needed.
Demand for heat or cold can be reduced by up to 60% by recovering waste heat from the electric motor and power electronics, as well as regulating air circulation and using a dehumidifier. This makes it possible to heat the car efficiently in winter and cool it inexpensively in summer. It also optimizes the battery’s efficiency, meaning the car can go much farther on a single charge.
