Lithium ion battery cell for battery management system utilized for storing electrical power for electromotor in e.g. hybrid motor car, has electrode-coil arranged within cell housing, and partially covered by pressure-sensitive film sensor

摘要

The cell (10) has an electrode-coil (20) arranged within a cell housing (12), and partially covered by a pressure-sensitive film sensor (30). The pressure-sensitive film sensor is designed as a tape circulating the electrode-coil, and comprises resistive, capacitive, piezoresistive or piezoelectric functional elements. An electrode terminal of the cell serves as a signal line for the pressure-sensitive film sensor, which is formed as a piezoresistive or piezoelectric film sensor. A thermo sensitive film sensor detects temperature in a region of the film sensor. An independent claim is also included for a battery management system.
