Repurposed Electric Vehicle Batteries For Standalone Street Lights


    Assoc. Prof. Dr. Gobbi Ramasamy
  • Description of Invention

    Existing street lights that use photovoltaic(PV) cells either requires a lead acid battery or grid power to charge them in event of extended rainy weather, like the tropical climates experienced in Malaysia. Our research proposes a lab scale proof of concept that using repurposed electrical vehicle batteries can be used to provide a reliable street light system while providing a cost effective and environmental friendly solution. The PoC showed that the street lamp system could be designed with 12% cost saving when using a repurposed battery. The product can be commercialized to property developers and highway concessionaires, as way to increase Malaysia' image as a green nation. The cheaper cost of street light deployment using the repurposed battery+PV system can increase rural street lights deployment penetration, improving safety and quality of life of rural dwellers.
