Abstract

An integrated simulation and testing approach is presented to evaluate batteries for electric vehicle (EV) applications. This new approach combines traditional experimental testing with first principles computer simulations, thus providing a cost-effective means to evaluate EV batteries and offer important information that is difficult or impossible to obtain from purely experimental measurements. The present simulators for lead-acid and Ni-MH batteries are developed based on the fundamental principles governing their electrochemical behaviors and created using an advanced computational fluid dynamics (CFD) technique. Computer simulations are validated by experimental data under the dynamic stress test (DST) procedure for a lead-acid battery module and a Ni-MH cell with good agreement. Moreover, computer simulations reveal that the studied lead-acid battery under-utilizes the active material by as much as 70% and the MH electrode of the Ni-MH cell is over-designed by about 30% under the simulated EV duty. Therefore, there is a great potential of increasing the specific energy and reducing the cost if batteries are designed specifically for electric vehicles using a simulation-based approach.
