Techno-Economic and Environmental Evaluation of Second-Life Battery PV Hybrid Charging Stations for Sustainable E-Mobility in Tropical Regions
This study presents a comprehensive evaluation of second-life battery (SLB) photovoltaic (PV) hybrid EV charging stations in tropical regions, using Malaysia as a case study. The research addresses the critical need for reliable, cost-effective, and low-carbon charging infrastructure to support the rapid growth of electric vehicle (EV) adoption, particularly under solar intermittency and high costs of new battery storage. The findings highlight the significant economic and environmental benefits of repurposing EV batteries for stationary applications.

Driving Cost-Efficiency with Second-Life Batteries
The implementation of Second-Life Batteries (SLBs) within solar-integrated EV charging stations offers substantial economic advantages, significantly reducing both capital expenditure (CAPEX) and operating costs. The modeled hybrid SLB-PV system requires an estimated capital investment of USD 17,000. The Levelized Cost of Storage (LCOS) was calculated at approximately USD 0.08/kWh, nearly 40% lower than the benchmark value of USD 0.13/kWh for new lithium-ion systems. This cost advantage primarily arises from reusing EV batteries that retain 70-80% of their original capacity, reducing raw material and manufacturing energy costs. Simulation-based cost modeling across 30 sensitivity cases showed CAPEX reductions between 30% and 50%, centered around a mean of 40%, confirming robust financial performance.
Advancing Sustainability and Circular Economy
From an environmental perspective, SLB-PV hybrid systems contribute directly to CO2 emission reduction and resource circularity. By offsetting approximately 90-120 kWh/day of grid-supplied electricity, each station avoids an estimated 1.2 tons of CO2-equivalent emissions per year. This is based on Malaysia's grid emission factor of 0.33 kg CO2/kWh. Furthermore, repurposing EV batteries extends their useful life by an additional 5-7 years, deferring recycling and reducing the environmental burden associated with mining, processing, and disposal. A Monte Carlo simulation confirmed the stability and resilience of these emission mitigation outcomes even under fluctuating tropical weather and operational conditions.
Ensuring Reliable Operations in Tropical Climates
The proposed SLB-PV hybrid EV charging station achieved an average renewable energy self-sufficiency ratio of 78%, meaning that nearly four-fifths of the charging demand was met by renewable energy rather than the utility grid. Experimental validation of repurposed CALB battery modules demonstrated stable degradation behavior, with only 3-4% capacity loss after 100 charge-discharge cycles. This confirms their suitability for stationary applications. Sensitivity analysis identified battery State of Health (SoH) and seasonal solar variability as critical factors influencing system reliability, emphasizing the importance of advanced Battery Management Systems (BMS) with real-time SoH monitoring and predictive maintenance algorithms.
