Abstract:

Aiming at the universal requirement of energy storage battery management system, a universal and real-time synchronous acquisition battery management system is proposed. The design of highly real-time synchronous acquisition scheme of the proposed system is introduced. The universal design of the system is expounded from four aspects: address adaptive design, all-channel temperature acquisition design, universal current sampling design and low power consumption operation mode design. The feasibility of the design scheme is verified by the theoretical analysis and experimental test data. The proposed battery management system can be widely applied to battery modules of different manufacturers. Through the actual operation, the complete battery cell data curves of the system are obtained and the feasibility of the system is verified.

Key words: battery management system, universality, synchronous acquisition, low power consumption
