Supercapacitors and batteries are storage technologies which have strengths for different applications. Supercapacitors are ideal where power bursts are required, long life backup power or a high number of charge/discharge cycles.
Supercapacitor specific power is typically 10 to 100 times greater than for batteries and can reach values up to 15 kW/kg. Ragone charts relate energy to power and are a valuable tool for characterizing and visualizing energy storage components.
The parameters of batteries and supercapacitors in a hybrid power system directly influence the performance of the power system. To achieve optimal performance from the hybrid power system, rational parameter matching design becomes particularly critical [10, 11].
The typical round-trip efficiency for a supercapacitor is greater than 98 percent, while LIB efficiencies are typically less than 90 percent. Battery management systems (BMS) are critical to ensure proper charging and discharging.
The supercapacitor is connected to the DC bus through the DC-DC converter, which actively controls the input and output power of the supercapacitor. This configuration effectively assists the battery in meeting the peak power demands of the electric loader, thereby reducing the impact of high currents on the battery. Figure 1.
However, since the output voltage of the supercapacitor is directly tied to the battery voltage, the supercapacitor cannot function within its full state of charge (SOC) range and fully realize its power handling capability, resulting in less volumetric efficiency.
