Scientists from Nanyang Technological University (NTU) and German Aerospace Centre (DLR) have invented a 2-in-1 electric motor that increases the range of electric vehicles. The engine integrates the traditional electric motor with the air-conditioning compressor, typically two separate units. This novel, space-saving design allows the use of bigger batteries, which can increase the range of electric vehicles by an additional 15 to 20 percent.
The new 2-in-1 design allows the electric motor to be more efficient in powering the car’s wheels, while its integrated air-con compressor uses less power due to synergy between the engine and the compressor, which can also tap on energy regenerated directly from the car’s brakes.
The innovation will pave the way for extending the range of electric cars, as the integrated design combines two of the most important parts of an electric car, thus reducing its complexity into one highly efficient solution. For automobile manufacturers, the new electric motor will also cost less to produce, as it requires less material than its counterparts. Both the weight and size of the electric motor are reduced, creating more space for other components such as an auxiliary battery source.
