BATTERY MANAGEMENT SYSTEM SENDING 2ND PROTECTION AND DIGNOSIS SIGNAL USING FEWER ISOLATION DEVICES

摘要

Disclosed is a battery management system which can send a secondary protection signal and a diagnosis signal by using fewer insulation devices. N number of battery management units included in the battery management system transmit two or more data to one communications line through time sharing. N number of data signals transmitted from N number of battery management units are transmitted gradually or by becoming one signal to an external device.
