The invention provides a battery residual life predication method and system. The predication method comprises the following steps: obtaining battery temperature T of a battery under a working state within an acquisition period [delta] t from the time tn-1 to the time tn, and calculating battery average temperature Tn in the period; according to the battery temperature of the battery and an accelerated life model corresponding to working time, calculating equivalent working time [delta] t' under the condition of reference working temperature Tk corresponding to the working time [delta] t and the battery average temperature Tn; calculating battery residual life Ln represented by the reference working temperature Tk at the time tn; and carrying out iterative calculation. The battery residual life predication method can calculate the service life of the battery in the working state in real time; and the adopted calculation method can set detection frequency according to use requirements, so that errors can be reduced as far as possible, and a technical effect of accurate prediction is achieved.
Description
Technical field [0001] The invention belongs to the field of battery reliability, and in particular relates to a method and system for predicting the remaining battery life, which can be used to predict the service life of a lead-acid battery used in a wind generator. Background technique [0002] The detection of the remaining life of lead-acid batteries in the prior art can predict the degree of aging and predict the remaining life based on the measured relevant parameters of the lead-acid batteries and the degeneration of the relevant parameters of the lead-acid batteries; some patents also disclose technical solutions , In which the used time is estimated, and then the used time is deducted from the design life to obtain the remaining life. The above two methods can only estimate the remaining life, but cannot achieve a more accurate prediction of the remaining life. Summary of the invention [0003] The embodiment of the present invention provides a method and system for pre...
