Development of a Two-in-One Motor System as a New Vehicle Energy Concept for Next Generation Car

Kurzfassung

Based on previous work a two-in-one-motor concept (TIOM) including an air conditioning compressor may increase the efficiency of electric driven cars by simultaneously reducing the total number of parts. The total energy saving results from two effects, switching between the two motors and operating them in its each best working point in addition of leading a part of the kinetic energy of the vehicle directly to the air conditioning compressor during recuperation events. The paper describes the development of such a double motor system coming from the drive concept design which depends on a chosen urban vehicle concept and leading over simulation to the design of the drive components and finally to the test of the total system.
