Résumé
The adoption of EVs as a mainstream option for vehicle buyers is underway globally. One challenge facing customers is the tradeoff in utility with respect to internal combustion-engine (ICE) vehicles in terms of driving range. Typical EVs may have a maximum range of 300 mi under favorable driving conditions, requiring the customer to stop and charge for longer trips. A 15 to 30-minute charging event might result in a range gain of around 200-mile whereas an ICE-equipped vehicle can typically refill to maximum range with a 5-minute fueling station stop. Advances in battery cell performance are an essential part of reducing the time to charge and increasing the range gain with each charge. Charging time is a particular challenge for large vehicle electrification, where lower vehicle energy efficiency results in larger energy requirements to achieve the same range gains. In this study, we examine the impact of an advanced battery cell chemistry on vehicle battery pack design and charging performance. An optimized battery pack design is developed using this cell; with a +8C average charge rate, the pack can theoretically accept a charge equivalent to 150 miles of energy in less than 5 minutes. However, there are pack volume and mass penalties relative to the baseline battery pack and reduced overall range due to lower cell energy density.
