Abstract: Considering that the supercapacitor group needs to be monitored and the individual capacitor voltage needs to be balanced continuously in energy hybrid supply system, this paper designed a supercapacitor group management and control system based on LTC6803, with upper and lower machine structure. The upper machine used Visual Basic as the monitoring platform and the lower machine used microcontroller AT89S52 to control LTC6803 so that the state of supercapacitor group was collected. The serial port between the upper machine and the lower machine realized data communication. The results show that the signal collected by the system has a little error and the supercapacitor group voltage is very balance with good performance.
Key words: supercapacitor; battery monitor LTC6803; voltage balance
