Title (EN) BATTERY CAPACITY ESTIMATION DEVICE, METHOD AND PROGRAM
(FR) DISPOSITIF, PROCÉDÉ ET PROGRAMME D'ESTIMATION DE CAPACITÉ DE BATTERIE
(JA) 電池容量推定装置、方法及びプログラム
Abstract:
(EN) This battery capacity estimation device is provided with: a condition variable acquisition unit (66) which acquires standard variable values (Tstd, Istd, V1std, V2std) indicating a standard charging condition in a secondary battery (30) and measurement variable values (Tmes, Imes, V1mes, V2mes) indicating an actual charging condition obtained by measurement; and a capacity estimation unit (68) which estimates the maximum capacity from a relationship between the standard variable values and the measurement variables acquired by the condition variable acquisition unit, wherein the capacity estimation unit calculates an apparent capacity (ΔQmes/ΔSOC) by using a uniform calculation method regardless of a change in charging condition, and estimates the maximum capacity (Qmax) by adding, to the apparent capacity, a correction amount obtained by using the differences between the measurement variables and the standard variables.
(FR) L'invention concerne un dispositif d'estimation de capacité de batterie comprenant : une unité d'acquisition de variable de condition (66) qui acquiert des valeurs de variable standard (Tstd, Istd, V1std, V2std) indiquant une condition de charge standard dans une batterie secondaire (30) et des valeurs de variable de mesure (Tmes, Imes, V1mes, V2mes) indiquant une condition de charge effective obtenue par mesure ; et une unité d'estimation de capacité (68) qui estime la capacité maximale à partir d'une relation entre les valeurs de variable standard et les variables de mesure acquises par l'unité d'acquisition de variable de condition, l'unité d'estimation de capacité calculant une capacité apparente (ΔQmes/ΔSOC) en utilisant un procédé de calcul uniforme indépendamment d'un changement de condition de charge et estimant la capacité maximale (Qmax) par l'addition, à la capacité apparente, d'une quantité de correction obtenue à l'aide des différences entre les variables de mesure et les variables standard.
(JA) 電池容量推定装置は、二次電池(30)における標準的な充電条件を示す標準変数値(Tstd、Istd、V1std、V2std)と、測定により得られる実際の充電条件を示す測定変数値(Tmes、Imes、V1mes、V2mes)を取得する条件変数取得部(66)と、条件変数取得部により取得された標準変数値と測定変数値の関係から最大容量を推定する容量推定部(68)と、を備え、容量推定部は、充電条件の変化によらず一律の算出方法を用いて見掛け上の容量(ΔQmes/ΔSOC)を算出し、見掛け上の容量に対して測定変数値と標準変数値の偏差を用いた補正量を加算して最大容量(Qmax)を推定する。
