Embodiment Construction
[0023] A method for estimating the remaining capacity of a lithium iron phosphate power battery, comprising the steps of:
[0024] 1. Establish the electrochemical model of the lithium iron phosphate power battery [the battery electrochemical model sees the (6) formula of the embodiment];
[0025] 2. According to the voltage equation of the electrochemical model, use the Kalman filter algorithm to obtain the remaining battery capacity:
[0026] Battery remaining capacity = the ratio of the average concentration of solid-phase lithium ions in the negative electrode of the battery to the maximum concentration of lithium ions when fully charged;
[0027] Among them, the solid-phase lithium ion concentration in the negative electrode of the battery is obtained through the extended Kalman filter algorithm; the maximum concentration of lithium ions during full charge is the calibration value at the factory, which is a constant.
[0028] In order to match the electrochemical model o...
