Fast parallel communication technology of power battery management system

In order to transmit parameter information of the power battery management system on electric vehicles to the overall control unit timely and accurately, the paper comes up with a solution of dual CPU fast parallel communication. In the example of the Ni-MH power battery management system applied on some hybrid power electric vehicles, the paper elaborates the application principles, and operation procedures of dual CPU fast parallel communication technology and software design of C8051F040/ C8051F060 SCM parallel communication. With the technology, transmission speed of the battery management system information has fully meet the period requirement of 10ms. Model hybrid power electric vehicles with the battery management system have successfully been in function.
