Abstract

For high-performance Electric Vehicles (EVs) that operate under aggressive driving conditions, dual Energy Storage System (ESS) may be applied instead of battery-only ESS to reduce mass, volume or initial cost. Using the proposed configuration methods, a quantitative criterion is put forward to judge the rationality of applying dual ESS with different driving cycles. Optimal configuration is acquired for selected dual ESS topology and vehicle prototype by Linear Programming (LP). Results show that compared to battery-only ESS, dual ESS can achieve lower mass and initial cost, but has higher volume.
