This study aimed to investigate the feasibility of mixed use of super-capacitor and lead-acid battery in power system. The main objectives are as follow: The mathematical model is established on the basis of circuit analysis. Research the key factors affecting power system efficiency.
The result are as follows: The charging efficiency is higher when the super-capacitor is charged preferentially. Sequential charging is adopted, with stable current, small fluctuation and better battery protection performance. This study demonstrated the development and prospect of hybrid super-capacitor and lead-acid battery power storage system.
This shows that the super-capacitor plays a role in protecting the battery and prolonging the service life of the battery. The hybrid energy storage device can increase the life cycle of the combined system, reduce the emission of waste batteries, and protect the environment.
Super-capacitor can greatly increase the output power of the battery. In Experiment 1, it has been determined that the existence of super-capacitor can alleviate the irregular voltage/current impact on the battery and improves the discharge efficiency of the battery. Experiment 2 is to explore the charging sequence and its influence on the battery.
Efforts to blend the characteristics of supercapacitors and Li-ion batteries have resulted in a hybrid supercapacitor called the Li-ion capacitor (LiC). This increases the supercapacitor's energy density while still offering faster response times than a battery.
In contrast to secondary batteries, super-capacitors, also known as “electrochemical double-layer capacitors” (EDLC), offer higher power density and life cycle but have considerably lower energy density. Super-capacitors currently find use as short-term power buffers or secondary energy storage devices in renewable energy, power systems [ 12, 13 ].
