Abstract: A power system for an electric vehicle comprising a battery pack connector unit and a battery assembly. The battery pack connector unit is electrically connected to a motor driver controller, and comprises at least a first battery connector and a second battery connector. The battery assembly includes at least a first battery pack and a second battery pack controlled by a first battery management system and a second battery management system respectively. When the first battery pack is electrically connected to the first battery connector, the first battery management system is arranged to become a master battery management system which is adapted to control the second battery management system as a slave battery management system, in such a manner that a respective voltage output of the battery assembly is optimally modulated by the master battery management system so as to create a single voltage output of the power system.

Abstract: This invention provides a method of computing dynamically the maximum power output to electric vehicle (EV) power train from the multiple and independently controlled battery packs to ensure safety and proper protection of the electric system. This method applies to an EV with multiple or extendable number of battery packs and provides fast computation of number of connected battery packs, the SOC of each battery pack, maximum power output of each battery pack and maximum power output of all battery packs combined.

Abstract: This invention provides a method of energizing electric vehicle (EV) power train with multiple and independently controlled battery packs. In this method, an EV can have one or more battery packs installed, only limited by the EV's physical spaces of the battery pack connector. All battery packs are interchangeable. Each battery pack has its battery management system (BMS) software and can either provide energy to the EV concurrently or individually. A typical embodiment of the invention comprises of a battery pack controller, a battery pack connector, a battery pack acting as the master (master battery pack), and optional slave battery pack(s). The battery pack controller connects electronically with the battery pack connector. The master battery pack, and optional slave battery pack(s) are mounted in the modular battery pack connector.

Abstract: The invention concerns to an electrophoretic separation device comprising a separation channel having at least one in- and outlet opening at the beginning and at the end of the channel and one electrode in the region of the inlet opening and one electrode in the region of the outlet opening. As well the invention concerns to a method for electrophoretic separation. The invention is characterized in that said separation channel is subdivided into at least two sections in series being coupled mutually by a joint providing an electrical connection means having a ion-conductive material separating said channel from a reservoir being apart the channel and provided with an electrode.
