| Zusammenfassung: | To provide a power supply system capable of more reliably detecting water immersion.SOLUTION: The present power supply system includes: a battery unit group in which a plurality of battery units are arranged while polarities in a vertical direction are aligned, each battery unit including a plurality of battery modules stacked electrically in series; a detecting section which detects parameters related to power supply of each of the plurality of battery modules; and a sensing section which senses water immersion in the battery unit group based on a comparison between predetermined parameters detected by the detecting section in any predetermined battery unit among the plurality of battery units and other parameters detected by the detecting section in any other battery units other than the predetermined battery unit among the plurality of battery units.SELECTED DRAWING: Figure 1
【課題】より確実に浸水を検知できる電源システムを提供する。【解決手段】本電源システムは、複数の電池モジュールを電気的に直列に積み重ねた電池ユニットを、上下方向における極性を揃えた状態で複数並べた電池ユニット群と、上記複数の電池モジュール夫々の電力供給に係るパラメータを検出する検出部と、複数の上記電池ユニットのうち何れかの所定電池ユニットにおいて上記検出部により検出された所定パラメータと、複数の上記電池ユニットのうち上記所定電池ユニット以外の何れかの他電池ユニットにおいて上記検出部により検出された他パラメータとの比較に基づき、上記電池ユニット群の浸水を検知する検知部と、を備える。【選択図】図１ |
