Abstract
Description
SOC_Usable=SOC0−(Q/DC)×100・・・(式2)
SOC0は充電および放電を開始する前のSOCを、Qは電流積算値(単位Ah)を、FCCは満充電容量を、DCは放電可能容量をそれぞれ示す。+は充電、−は放電を示す。
FCC=(Qt/ΔSOC)×100 …(式3)
ΔSOCはSOC_FULLの変化値、QtはΔSOCに要した区間容量(単位Ah)をそれぞれ示す。以下、放電時の区間容量を放電区間容量と称し、充電時の区間容量を充電区間容量と称する。
Qt’=Qt×αt …(式4)
Qt’=Qt×αi …(式5)
αtは温度補正係数を、αiは電流補正係数をそれぞれ示す。図5は、温度補正テーブル62a及び電流補正テーブル62bを示したものである。温度補正テーブル62a及び電流補正テーブル62bは、補正テーブル62に含まれるデータである。温度補正テーブル62aは、温度センサ450により検出される温度Tdと温度補正係数αtの対応関係を記述したテーブルである。電流補正テーブル62bは、電流センサ440により検出される電流値Idと電流補正係数αiの対応関係を記述したテーブルである。
