Parameter estimation system, parameter estimation device, vehicle, computer program and parameter estimation procedures

摘要

A first parameter estimation device shall comprise a sequential estimation unit which is configured to estimate sequentially the parameters of a secondary battery replacement switch based on a current and a secondary battery voltage, when charging or discharging the secondary battery on the basis of a power sample. A second parameter estimation device includes: a collective estimation unit that is configured to collectively estimate parameters of secondary battery replacement switching based on a current and voltage collected; and an output unit that is configured,to issue the estimated parameters to the first parameter estimation device. The first parameter estimation device also includes an update unit configured to update the sequentially estimated parameters with the collectively estimated parameters.
