电池充电率计算装置
摘要：
电池充电率计算装置(100)包括：SOCV计算单元(5)，输出基于电压数据算出的第1充电率；SOCI计算单元(6)，输出基于电流数据算出的第2充电率；估计阻抗电压计算单元(12)，基于有效充电率和电流数据计算阻抗电压值；稳定判定单元(7)，判定所述阻抗电压值在以规定的阈值区分的范围内稳定了规定时间以上的情况，并输出该判定结果；以及SOC决定单元(20)，基于所述判定结果，在所述阻抗电压值稳定了的情况下，将所述第1充电率作为所述有效充电率输出，在除此之外的情况下，将所述第2充电率作为有效充电率输出。
摘要（英）：

Disclosed is a battery state of charge calculation device (100) equipped with an SOCV calculation unit (5) that outputs a first state of charge calculated based on voltage data, an SOCI calculation unit (6) that outputs a second state of charge calculated based on current data, an estimated impedance voltage calculation unit (12) that calculates an impedance voltage value based on the effective state of charge and current data, a static decision unit (7) that determines that the impedance voltage value has remained static for longer than a prescribed time within a range delimited with prescribed threshold values and outputs the decision result, and an SOC determination unit (20) that, based on the decision result, outputs the first state of charge as the effective state of charge when the impedance voltage is static, and otherwise outputs the second state of charge as the effective state of charge.
