Research on Design of Management System for Power Source Equalizing Charge based on FPGA control

摘要

The accumulator can store the energy in high capacity, and the super capacitor can charge and discharge in high power. The mixed power source composed by the accumulator and super capacitor not only has the characteristics for both of them but also meets the high-power requirement of high capacity and peak value. How to perform the equalizing charging for multiple power packs is a emphasis in the industry currently. On the basis of analysis for multiple equalizing charging methods, a new type of design scheme based on DC/DC and switch matrix is raised in this project, the thinking of intermittent charging mode is adopted and four BCAP0350 is served as the charging sample to perform the charging and discharging experiment as well as verify the composite charging design scheme is provided with the feasibility.
