Design method for cell charge state prediction kernel

The invention provides a design method for a cell charge state prediction kernel, and the kernel can predict a cell charge state value according to inputted voltages, charge and discharge rates and charge and discharge modes. The design method includes: (1) a charge/discharge mode identification module; (2) a rate identification module; (3) a voltage identification module; (4) a charge state prediction kernel module. According to the design method, part of characteristic point reflecting the change of the cell charge state is selected to establish a static cell characteristic and dynamic charge/discharge characteristic database, and the characteristic points in the database are used to evolve the cell charge state prediction kernel. The design method is characterized in that the cell charge state at any characteristic point can be predicted as long as the information (charge and discharge modes, rates, voltages and other data) of the characteristic point is inputted into the input end of the cell charge state prediction kernel.
