Open circuit voltage method: and sampling terminal voltage attenuation of the battery within a certain time in real time, looking up a table to obtain the residual energy of the battery, and correcting the obtained residual energy of the battery by considering the influence of the service life and the internal resistance of the battery on the charge state of the battery. The method requires the battery to be kept still for a long time, and is not favorable for quick and online detection.
Impedance method: and exciting the battery by using alternating currents with different frequencies, measuring the alternating current resistance in the battery, and obtaining the estimated value of the state of charge through the established calculation model. Due to the complex relationship between the battery state of charge and the resistance parameters, modeling is difficult.
Other methods such as kalman filtering method and neural network method rely on the established model, the adopted algorithm and computer processor.
