The configuration of EV system using battery module balancing method

In the electric vehicle(EV) system, the Technology for the efficient operation of a battery is one of the most important technologies. By the voltage difference between the cell and between modules of electric car battery, it will not be able to efficiently use the battery. Using the voltage balancing method to each of the battery modules to increase the available space for the battery module, it is possible to more efficient battery operation. This paper provide the EV system of applying the Balancing method of the battery module and the torque control of interior permanent magnet synchronous motor(IPMSM) for EV using this method.
