The monitoring and protection system of the super capacitor in a large-current discharge experiment system is designed. The monitoring and protection system is made up of the man-machine interfaee~ the intelligent ammeter and the programmable logic controller, which is able to achieve the real-time parameters and status displayi the detailed parameters and status display of a single super capacitor, the self-protection of the system, the super capacitor warning linkage, the super capacitor alarm linkage, the super capacitor settings, the ＇alarm recording and event logging and query. In addition, this paper focuses on the CAN communication to achieve, the realization of self-protection systems, pre-alarm linkage and other key technologies. Engineering operation results show that the system is running very reliable and the technology is worth, promoting.
