Supercapacitors (5–10 % per day) have the fastest self-discharge, followed by lead-acid batteries (10–15 % in first 24 h, then 1–3 % per month), and Li-ion batteries (2–3 % per month) have the slowest self-discharge rate. Supercapacitors achieve remarkably high capacitance through a combination of electric double layer formation at electrode–electrolyte interfaces and pseudo

This synergistic operation favors an extended battery life. The lead-acid battery pack was proved effective in providing a sustained power for PV peak power shaving purposes, and also to limit the power ramp rate at the circumstance of exhausting the energy storage capacity of the supercapacitor.

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.
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.
Techniques employed for lithium-ion batteries as the mapping of the available power with respect to the state of charge level (i.e. the so-called State of Available Power, SoAP metric) would enhance the power scheduling of the lead-acid battery.
Firstly addressing the grid power peak shaving service, the following state of charge limitations are adopted for the supercapacitor (sub-index 1) and the lead-acid battery packs (sub-index 2): SOCmax1 =0.7 p.u., SOCmax2 =0.95 p.u., SOCmin1 =0.50 p.u., SOCmin2 =0.25 p.u.
