Nickel Metal Hydride (NiMH) batteries are exothermic during both charge and discharge operating environments. When considering NiMH batteries for vehicles in severe operating environments, such at those requiring high-current, rapid discharge operations, the battery temperature is the limiting factor. Battery temperature control during charging can be accomplished with forced air ventilation utilizing external power sources. However, during discharge, the temperature control system must be on the vehicle with operating characteristics including lightweight and little or no power required. To fully evaluate NiMH batteries in highcurrent discharge operating regimes, researchers first modeled the battery using Inertia, a Finite Element Analysis (FEA) software package. Using the FEA results as a basis, a temperature control strategy was developed and a battery pack cooling system designed. As a validation method of the FEA model, bench testing of NiMH modules was conducted This paper reports on the FEA modeling along with the results of the bench testing of the batteries in this severe operating regime.
