COMMUNICATION ERROR ATTENUATION FUNCTION WITH DISTRIBUTED BATTERY MANAGEMENT SYSTEM

摘要

The invention provides a distributed battery management system with a communication error attenuation function. The distributed battery management system comprises a plurality of component modules formed by serially or parallelly connecting a plurality of components; a plurality of component circuit modules accessing to the component modules and collecting the state information of component modules; a battery management unit receiving component or component module state information collected by the component circuit modules; and a control unit controlling the battery management unit and further controlling the output of the component modules. The component circuit modules are mutually accessed in a serial link way so as to sequentially transmit component module state information collected by an upper component circuit module to a lower component circuit module. Then accumulated state information of each component module is transmitted to the battery management unit. A first accessing part and a second accessing part are configured inside the component circuit modules of the battery management unit. The backflow noise inside the component circuit modules and the noise generated during processes of communication among component circuit modules are attenuated. The system is thus enabled to achieve precise output control.
