Supercapacitor controller of fuel cell-super cap bus system

摘要

A super-capacitor controller for a fuel cell super-capacitor hybrid bus is provided to reduce a production cost by sharply decreasing the number of cell balancing circuits. A super-capacitor controller(300) of a fuel cell super-capacitor hybrid bus includes a plurality of control modules(310), an analog MUX(Multiplexer)(320), an amplifier(330), an external interface(350), a central processing unit circuit(340), and a power supply unit(360). The control modules partially divide a plurality of super-capacitor single cells(120a) into groups and are connected to super-capacitor single cell units(120b) divided into groups respectively. The analog MUX integrates voltages outputted from the control modules by being connected to the control modules. The amplifier amplifies the output of the analog MUX. The external interface connects the capacitor and other components. The central processing unit circuit distributes the output of the amplifier to the components connected through the external interface. The power supply unit transmits power to the controller.
