Device for monitoring and controlling cells of lithium ion accumulator for e.g. electric vehicle, has electrical insulation module, central control unit and cell monitors that are monolithically integrated in semiconductor component

摘要

The device has a cell monitor (202) for monitoring the cells (100-1-100-n), and a central control unit. Several electrical insulation modules are galvanic decoupled between cell monitors and central control unit, and are provided with organic light emitter and photodetector. The electrical insulation module, central control unit and cell monitors are monolithically integrated in semiconductor component. An independent claim is included for accumulator management system.
