Battery cell module for battery system of e.g. electric-motor driven motor car, has lithium ion battery cell, and switch that is provided for automatic separation and restoration of electrical connection

摘要

The battery cell module (10) has a lithium ion battery cell (11) that is provided with two terminals, and is connected with an electronic monitoring unit (13) by an electrical connecting line (12). A switch (14) is provided for automatic separation and restoration of electrical connection. The source and drain of MOSFET is connected with the battery cell. The monitoring unit is connected with the battery cell. The battery cell is arranged between the source/drain and gate of MOSFET. An independent claim is included for a motor car.
