BATTERY TEST RIG AND BATTERY MANAGEMENT SYSTEM FOR RECYCLING LI-ION CELLS FOR AUTOMOBILE BATTERY PACK
Keywords:Battery Test rig, BMS (battery management system), Audrino nano, Li-ion (18650) cell
The In the upcoming automobile market where the battery vehicle can dominate the industry is in need of resources. Scavenging the used battery cells for new battery packs is going to help to overcome the shortage of resources. Our project emphasizes on the idea of reusing the resources available and testing it for safety and avoid any catastrophic failure that may occur due to scavenging. The world moving fast towards the implementation of electric vehicles (EV’s) in the next decade. The rise in portable devices and the implementation of technology anywhere and everywhere possible has caused rise in demand for the battery technology. Li-ion battery which are popularly used in every device available today has huge upside potential and very few downsides. Li-ion batteries are opted for every devices due to the least self-discharge capabilities, energy density and its capacity to maintain constant voltage throughout discharge cycle. Our project aims to check the parameters of the battery measure its life cycles, SOC (state of charge), SOH (state of health), discharge and charge cycles using battery test rig fabricated by the team and also create a battery management system and discuss the problems in battery safety and demands in auto sector come up with the solution for the problems. Batteries which are properly maintained can live up to decade with around 25% degraded capacity. The degradation of the battery is also conducted in the project using the HP elite book 2560p Battery pack and its in-built software to determine the battery parameters. The battery pack has 3S configuration with 11.8v and 5000mAh capacity.
