Supercapacitors hybrid energy storage systems typically combine the high energy density of batteries with the high power density of supercapacitors, providing more stable and efficient power supply under different load conditions. In this system, the battery is mainly responsible for long-term energy supply, while the supercapacitor is used for rapid charging and discharging to meet instantaneous power demand. The two are connected to each other through a bidirectional DC-DC converter to achieve dynamic energy allocation.

1. Fast charging and discharging: Supercapacitors have extremely fast charging and discharging speeds, as well as power compensation speeds. Especially when starting high-power equipment or in emergency situations, they can quickly release stored charges, reducing engine start-up time and mechanical wear.

2. Long cycle life: Supercapacitors have a long cycle life and can withstand millions of charge and discharge cycles, far exceeding the lifespan of traditional batteries, making them suitable for long-term use in construction machinery.

3. Superior low-temperature performance: Supercapacitors still have superior performance in low-temperature environments and will not be severely affected by temperature drops, making their application in construction machinery in cold environments possible.

4. Energy recovery: Supercapacitors can quickly recover the remaining energy generated during braking, improve energy utilization efficiency, and reduce environmental impact. In construction machinery, brake energy recovery is an important energy-saving method that can significantly improve the energy efficiency of equipment.

1. Start up assistance: During the start-up of construction machinery, supercapacitors can provide additional current support to help the engine start quickly, reduce start-up time and wear.

2. Braking energy recovery: During the braking process of construction machinery, supercapacitors can recover the energy generated during braking and store it for subsequent use, thereby improving energy utilization efficiency.

3. Load balancing: Supercapacitors can balance unstable loads in construction machinery, improve the stability of electrical systems, and reduce the risk of electrical equipment damage.

4. Improvement of power quality: Supercapacitors can alleviate voltage fluctuations in electrical systems, improve power quality, and reduce the operation and maintenance costs of electrical systems.
