| 摘要 |
The circuit has lithium ion cells (4) that are connected in series (A-D) through cell connectors (Z0a-Z10a,Z0b-Z10b,Z0c-Z10c,Z0d-Z10d). The compensation lines (L1a-L10a,L1b-L10b,L1c-L10c,L1d-Ld10) are provided for electrically interconnecting the cell connectors of different rows. The potential (U1r-U10r) of cell connector connected to compensation line of cell rows, and the potential (U1l-U10l) of corresponding cell connector connected to compensation line of other parallel cell row are detected. The detected potentials are output to evaluation unit (10). |
