Abstract
Vehicle electrification increases the fuel efficiency of the transportation sector while lowering emissions. An automotive battery is an example of [wet-cell] battery with 6 cells. The very most Important component of a vehicle is a battery, used for powering regenerating and lithium -ion battery has been widely used due to its superiority to conventional lead –acid and Ni-MH batteries is terms of power capability. Besides the high specific power, li-ion battery has many other significant features . Here focused on the design of compact battery pack with desired structural safety and high cooling performance. The weight of the battery was minimized by applying optimization methodology with Finite Element Analysis [FEA]. Efficient cooling system was also achieved through Computational Fluid Dynamic [CFD] analysis , to have uniform temperature distribution and minimized pressure drop within the pack under normal charging and discharging conditions. By employing module frame and cooling system based on numerical simulation, a prototype of compact battery was manufactured. Experiments were also carried out on this optimized prototype of battery pack to further validate numerical simulation.
