Description
technical field [0001] The invention relates to the technical field of fuel cell vehicles with three energy systems, in particular to a supercapacitor control system and method for fuel cell vehicles with supercapacitors. Background technique [0002] At present, fuel cell vehicles have become a development trend, but most of them use power batteries as auxiliary energy sources. The charging and discharging performance of the power battery is greatly affected by temperature, the charging and discharging power is small, the energy generated when the vehicle is braked cannot be fully recovered, and the number of charging and discharging is small. Supercapacitors are famous for their wide operating temperature range, high charging and discharging power, and many charging and discharging times. It can be seen that the performance of the power battery and the super capacitor are complementary, and the auxiliary energy system composed of the power battery and the super capacitor ...
