MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617089761 A) filed by Mitsubishi Electric Corporation on July 23, 2026, for Estimation Device And Estimation Method.
Inventors include Yoshida, Yukihiro; and Takegami, Tomoki.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: An estimation device (1) comprises an estimation unit (3) that estimates at least a parameter using a storage battery state space model (21) that includes at least a resistance as a parameter, such estimation performed on the basis of the current of a storage battery (50) detected by a current detection device (51) and the voltage of the storage battery (50) detected by a voltage detection device (52). The estimation unit (3) comprises: an inverse sigmoid transformation parameter estimation unit (31) that estimates an inverse sigmoid transformation parameter obtained by performing inverse sigmoid transformation of the parameter; and a sigmoid transformation unit (32) that obtains as an estimated value of the parameter a sigmoid transformation parameter obtained by performing sigmoid transformation of the estimated inverse sigmoid transformation parameter.
