Development of the experiment platform for electric vehicles by using motor test bench with the same environment as the actual vehicle

In this paper, the experimental platform using motor test bench with same environment as the actual vehicle is developed. In the previous paper, the experiments were performed by using motor test bench[2]. These experiments were performed under the condition of the constant DC-supply voltage. However, the output voltage of the battery used in the actual EV is changed depending on the state of charge (SOC). Furthermore, flux weakening control was not applied to the inverter at the previous motor test bench. This is why exactly one charge driving range could not measured. In order to solve these problems, this paper develops the experimental platform (motor test bench) with following two things; 1) construction of the battery emulation system, and 2) adaptation of the flux weakening control to the inverter. The experiments was implemented for verification of the validity of the experiment platform (motor test bench). From these experimentalal results, it was confirmed that the experiment platform (motor test bench) can simulate the actual vehicle.
