Chargeable-and-dischargeable power supply system
First Claim
1. A chargeable-and-dischargeable power supply system, comprising:
- a plurality of battery cell sections connected in series with one another, each battery cell section being constituted by at least one charging section;
a plurality of cell state detecting sections installed for the respective battery cell sections and configured to detect a charge state of the charging section of the respectively corresponding battery cell sections;
a power control section configured to carry out a power supply control for the battery cell sections;
a first electrical isolation section installed in a first signal route from the power control section to one of the cell state detecting sections which is for a highest potential positioned battery cell section of the battery cell sections; and
a second electrical isolation section installed in a second signal route from one of the cell state detecting sections which is for a lowest potential positioned battery cell section of the battery cell sections to the power control section.
