Impact Analysis of Lithium-Ion Battery Storage System on Sustainable Energy-Generating Pad Applications

The generation of electricity from Renewable Energy (RE) sources is the best alternative worldwide because of the current geopolitical and environmental situations. An efficient energy storage system is vital to making a sustainable RE system. The standard electrical energy storage devices are Nickel, Lead-acid batteries, Supercapacitors, and Lithium-ion Batteries. However, energy storage in lithium-ion batteries is the best choice today because of their long lifetime, high energy density, and low energy loss at shelf-discharging. In this research, A Sustainable Energy Generating Pad (SEGP) for bike lane applications has been developed and prototyped in the SMART Center at PV AMU. Impact energy from running bikes on SEGP was stored by a lab developed novel Dual-Stage Charging System (DSCS) using 18650 lithium-ion batteries. In the lab experiments, from a 3-foot-long SEGP, energy stored in a lithium-ion battery in the first stage of the DSCS was around 11 mWh/cell. The maximum Voltage reached around 4.2 V. Finally, the results tested were compared and verified. The results were similar by approximately 97%, corresponding to two case studies by well-known companies such as Toshiba and Samsung.
