Abstract
Description
本開示は、上述の課題を解決するためになされたものであって、その目的は、電池の異常検出の精度を向上させる技術を提供することである。
図1は、本実施の形態の電池システム100の構成例を示す図である。電池システム100は、組電池50と、複数のセンサと、コントローラ80と、1以上のリレー90とを備える。複数のセンサは、電圧センサ11と、第1温度センサ31と、第2温度センサ32とにより構成される。
(1) 図5は、コントローラ80に対する組電池50の異常(たとえば、単位電池5の過度な温度上昇)による影響を低減させる他の手法を説明するための図である。図5の例では、防壁200を設けるのではなく組電池50とコントローラ80との物理的距離Lが確保されている構成が示されている。組電池50とコントローラ80とが、物理的距離L離間されている構成であっても、コントローラ80に対する単位電池5の異常による影響を低減できる。
