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 during vehicle braking cannot be fully recovered, and the number of charging and discharging times is small. Supercapacitors are known for their wide operating temperature range, high charge and discharge power, and high number of charge and discharge times. It can be seen that the performance of the power battery and the super capacitor complement each other, and the auxiliary energy system composed of the power battery and the super cap...
