Content Inside:
Computational Fluid Dynamic (CFD) analysis was performed using FLUENT to analyze the fluid thermal performance of a Battery cell container for the Ford Fusion Hybrid Electric Vehicle. The objective of the design was to maintain the cells in their desired operating temperature range with a near uniform temperature among the battery cells in the container, while minimizing energy losses associated with the pressure drop. Hybrid electric powertrains are an effective and practical technology to improve a vehicle’s fuel economy without compromising the vehicle’s performance. One key element of a hybrid electric powertrain is the high voltage traction battery system, hereafter referred to as a battery, which has the functions of providing and receiving electrical power as demanded by the electric machine(s) as well as storing the energy when none is demanded. Design and analysis of the battery, The cells studied contain nickel metal hydride chemistry, in a D-size form factor. Four cells are welded end to end to form a battery
module. Two modules are positioned parallel to one another and retained in a plastic housing referred to as a brick. Computational Domain of CFD Simulation: The inlet to the computational domain was located axially about 20 mm upstream of the inlet bus bar.
