Obergrenzen-Ladungszustandsschätzeinrichtung und Verfahren zum Schätzen eines Obergrenzen-Ladungszustands

A PM-ECU executes a program including: a step (S104) of estimating pre-charge SOC(1) when a plug-in charge is started (YES in S100), a step (S108) of calculating an integrated value of charging current when integration permitting conditions are satisfied (YES in S104, YES in S106), a step (S112) of...

Summary:A PM-ECU executes a program including: a step (S104) of estimating pre-charge SOC(1) when a plug-in charge is started (YES in S100), a step (S108) of calculating an integrated value of charging current when integration permitting conditions are satisfied (YES in S104, YES in S106), a step (S112) of setting a final integrated value when the charge is completed, a step (S116) of estimating post-charge SOC(2) when an ignition switch is turned on (YES in S114), a step (S122) of calculating a full-charge capacity of this cycle when calculation conditions are satisfied (YES in S120), a step (S128) of calculating a new full-charge capacity when the full-charge capacity of this cycle is within a specified range (YES in S124), and a step (S130) of updating the full-charge capacity by setting the new full-charge capacity as the current full-charge capacity when the new full-charge capacity is within a specified range (YES in S128).
