Abstract
A state-of-charge (SOC) online estimation method of an intelligent battery includes steps of performing online estimation on the SOC based on a real-time estimation model, wherein the real-time estimation model is based on an equivalent circuit model, and then obtaining online estimates of the SOC through the SOC-OCV (open circuit voltage) relationship, the current-voltage relationship under different working conditions, and the current terminal voltage and temperature of the intelligent battery. The intelligent battery that is able to apply the SOC online estimation method includes a battery cell and a cell management unit, wherein the cell management unit includes a sensor module, a switching device, a controller module, a communication module and a printed circuit board (PCB), the sensor module includes a voltage sensor and a temperature sensor; the voltage sensor, the temperature sensor, the switching device, the controller module and the communication module are integrated on the PCB.
