2 Secondary battery sub Unit Secondary battery management system and Method for exchanging information in multi-pack parallel structure using the same

摘要

The present invention relates to a secondary battery, and more particularly, to a secondary battery management system and method for information exchange in a multi-pack parallel structure using the same, more specifically, to a battery module comprising a plurality of battery cells coupled in series, (Voltage Temperature Management System) that measures the voltage and temperature of each battery cell. This makes it possible to increase the number of battery cells and increase the energy capacity, and to exchange information in a multi-pack parallel structure using the secondary battery. And a secondary battery management system and method for the secondary battery. According to the present invention, a VTMS (Voltage Temperature Management System) is connected to each battery module composed of a plurality of serial unit battery cells, and the battery module and the VTMS are combined into a plurality of battery packs, It is possible to safely operate the system and prevent fire even while driving in spite of the increase of the number and the increase of the energy capacity.
