Document Type and Number:
WIPO Patent Application WO/2020/090429
Kind Code:
A1
Abstract:
According to the present invention, a first parameter estimation device comprises a serial estimation part that serially estimates a parameter for an equivalent circuit of a secondary battery on the basis of the current and voltage of the secondary battery when the secondary battery has been charged or discharged on the basis of a current pattern, and a second parameter estimation device comprises a combined estimation part that combinedly estimates the parameter for the equivalent circuit of the secondary battery on the basis of aggregated current and voltage and an output part that outputs the estimated parameter to the first parameter estimation device. The first parameter estimation device additionally comprises an updating part that uses the combinedly estimated parameter to update the serially updated parameter.
