“…To work in parallel, additional DC/DC converters can be used to isolate the battery packs to ensure safety [29]. Integrating the battery pack with the converter into a battery power module to form a larger battery pack architecture makes it easier to build flexible and stable units [28,30,31]. However, it is still better to direct power bus mount without the converter for economy, reliability, and energy efficiency.…”

To improve the reliability and energy efficiency of battery swapping, we constructed a battery power network system with active redundancies and with multiple battery management controllers (one in each newly developed smart redundant battery pack). Each pack is getting ready to assume the role of the major to coordinate direct safe mounting of the packs onto the power bus for load sharing or charging without the need for a direct current to direct current converter. This fault-tolerant architecture provides multiple backups in both management control and power supply. To verify this design, the mounting, insertion, and removal of the battery packs were executed during charging and discharging. Battery packs can be swapped on and off safely at any time regardless of their charging states. Battery packs can be direct safe mounted onto the power bus by a threshold algorithm. With each mount on event, the equivalent output energy conversion efficiency ranges from 98.3% to 99.2% throughout the transient. Moreover, when the major battery pack fails or gets removed, other battery packs can indeed assume the role of major safely. The reliability, energy efficiency, and safety of our system were verified.

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.
