Abstract:
(EN) This estimating device for estimating the state of charge (SOC) of an electricity storage element 31 is provided with a current measuring unit 41, an estimating unit 50, and a modifying unit 50. The estimating unit 50 executes: an estimating process of estimating the SOC of the electricity storage element 31 by integrating the current measured by the current measuring unit 41; and, if a prescribed correction condition has been reached, a correction process of correcting an error in the estimated value of the SOC by charging the electricity storage element 31 to full charge or close to full charge. The modifying unit 50 modifies the correction condition in accordance with the state of the electricity storage element 31.
(FR) Ce dispositif d'estimation pour estimer l'état de charge (SOC) d'un élément de stockage d'électricité 31 est pourvu d'une unité de mesure de courant 41, d'une unité d'estimation 50 et d'une unité de modification 50. L'unité d'estimation 50 exécute : un processus d'estimation consistant à estimer l'état de charge de l'élément de stockage d'électricité 31 en intégrant le courant mesuré par l'unité de mesure de courant 41; et, si une condition de correction prescrite a été atteinte, un processus de correction consistant à corriger une erreur dans la valeur estimée du SOC par recharge de l'élément de stockage d'électricité 31 à pleine charge ou près de la pleine charge. L'unité de modification 50 modifie la condition de correction en fonction de l'état de l'élément de stockage d'électricité 31.
(JA) 蓄電素子31のSOCを推定する推定装置であって、電流計測部41と、推定部50と、変更部50と、を備え、前記推定部50は、前記電流計測部41により計測される電流の積算により前記蓄電素子31のSOCを推定する推定処理と、所定の補正条件に達した場合、前記蓄電素子31を満充電又はその近傍まで充電し、前記SOCの推定値の誤差を補正する補正処理と、を実行し、前記変更部50は、前記補正条件を、前記蓄電素子31の状態に応じて変更する。
