    Abstract: A secondary battery packing case structure is provided, where a first joint portion that protrudes outward and a first embedded block are formed on a side surface of the case, a second joint portion that protrudes outward and a second embedded block are formed on another side surface opposite to the foregoing surface, and the first joint portion and second joint portion of the case are in a diagonally symmetric state, the first embedded block and the second embedded block are in a diagonally symmetric state, and the second connector group of the case may be correspondingly connected to a first connector group of another same case in an inserted manner; and connector groups on two joint portions of the case are respectively electrically connected to two electrodes of an internal battery pack. In this way, a single packing case can completely isolate an anode and a cathode of a battery pack in the packing case, and when multiple cases are connected in series, in a status that no short-circuit component is installed, a battery in the case cannot discharge electricity, which can completely avoid a situation that an accident short circuit or activation occurs in the battery and ensure security of the battery in a series connection and a transportation process.

    Abstract: A lithium battery cell structure is provided. A first-electrode conduction portion and a second-electrode conduction portion that are exposed outward are respectively provided on two sides of a soft package lithium battery inside the metal housing. The first-electrode conduction portions are respectively electrically connected and fixed to a first-electrode conductive sheet, and the first-electrode conductive sheet is electrically connected and fixed to a housing conductive sheet that is connected to the metal housing. The second-electrode conduction portions are respectively electrically connected and fixed to a second-electrode conductive sheet, and an other end of the second-electrode conductive sheet is electrically connected and fixed to the second electrode end. By adjusting the design of electrical connection between extending portions and the soft package lithium battery and the housing, the lithium battery cell is enabled to have better electrical conductivity and a better heat dissipation effect, and the sealing procedure made simpler.

    Abstract: A battery charge-discharge balancing circuit assembly used in a battery pack consisting of multiple secondary battery cells is disclosed to include a switch device installed in each of the positive and negative terminals of each secondary battery cell and a balancing resistor connected with all the secondary battery cells in a parallel manner and the balancing resistor device having two opposite ends thereof connected the switch devices in series. All the secondary battery cells or multiple secondary battery cells of the battery pack can share one balancing resistor. By means of discharging the secondary battery cells in rotation, every secondary battery cell gets balanced to achieve efficient charging, eliminating the problem of overheat of the prior art technique.

    Abstract: A power supply system using an energy storage cell includes at least one lithium cell module; a voltage balance device, received and built in the lithium cell module, for performing voltage balance; and a cell module voltage monitoring device, disposed between a load and the lithium cell module, for monitoring and controlling working voltage ranges of all the lithium cell modules. The voltage balance device built in each lithium cell module performs charging correction on a lithium cell unit in which a capacitance difference is caused by a fabrication process or caused subsequently, to prevent overcharge damage of the lithium cell unit caused by the capacitance difference. The cell module voltage monitoring device is provided on an external line, and only a correct total charge voltage needs to be provided to charge the lithium cell module.
