    Abstract: A battery system includes several unit battery groups, a main switch, a current measuring unit, several slave control units and a master control unit. Each unit battery group includes several cells. The main switch and the current measuring unit are serially connected to the unit battery groups. The current measuring unit measures a measured system current value of the unit battery groups. The slave control units are electrically connected to the unit battery groups respectively. Each slave control unit measures a physical parameter value of each cell in each unit battery group. The master control unit communicates with the slave control units to: disconnect the main switch when the abnormality determined according to the physical parameter value or the measured system current value pertains to system abnormality; and, perform a processing procedure for detection abnormality when the abnormality pertains to detection abnormality.

    Abstract: A battery system, a control method of a cell balance procedure and a calculation method of a balance charge capacity are provided. The battery system includes a plurality of battery units, a communication bus and a host control unit. Each battery unit includes a plurality of cells, an isolated charger, a switch array circuit, a balance slave switch and a balance slave controller. The host control unit includes a balance host controller, a balance host switch and a system current measurement unit. When the error between a balance detection voltage calculated by each balance slave controller and the balance detection voltage calculated by the balance host controller is less than a predetermined value, the balance host switch and the corresponding balance slave switches are in conduction and the specified plurality cells of battery system are charged for keeping cell balance purpose.

    Abstract: The disclosure provides a battery busbar including a conductive sheet, at least two bridge portions and at least two terminal contact portions. The conductive sheet has at least one cavity portion. Each of the at least two bridge portions has a first end and a second end which are opposite to each other, and the first ends of the bridge portions are respectively connected to different sides of the at least one cavity portion. The terminal contact portions are spaced apart from each other and are respectively connected to the second ends of the bridge portions. A width direction is defined to be substantially perpendicular to a line passing through the first end and the second end of one of the at least two bridge portions; along the width direction, a width of the bridge portion is smaller than a width of the terminal contact portion.
