Abstract


The electric car is the best solution to solve the energy crisis and environmental pollution . Super capacitors and batteries are the ideal energy storage unit , its features better than traditional nickel-metal hydride batteries and lithium batteries . Super capacitor energy management system at home and abroad in its infancy Firstly, the characteristics of the supercapacitors made ??a more detailed description with reference to the nickel-metal hydride , lithium battery SOC theory proposed for supercapacitor SOC algorithm . This paper introduces the the supercapacitor management system -level management mode : the subordinate management system and upper management system . Designed supercapacitor pressure functional unit , and that lower-level management system , to protect the work properly when upper management system failure , the entire super capacitor bank . And is designed as a data transmission channel into two CAN bus \The software is the core of the system , the system in each unit using the embedded real-time operating system μC/OS- Ⅱ system , the paper focuses on the management of the various parts of the task as well as in the TMS320LF2407A on transplantation , a part of the core code .
