Abstract:

Electrification of transport relies on lithium-ion batteries in electric vehicles (EVs), yet conventional fixed-configuration battery packs (CBPs) suffer from structural inefficiencies such as cell-to-cell variability and premature failure. Dynamic battery reconfiguration, enabled by intelligent control of switching hardware, offers a promising alternative. In this work, we present a systematic, battery technology-agnostic evaluation of lifetime and economic benefits of reconfigurable battery packs (RBPs), using a statistically grounded framework based on detailed cell modelling across diverse EV design and usage conditions. We show that RBPs can extend battery lifetime by over 20%, particularly in high-voltage applications such as electric trucks and longrange EVs. Despite higher upfront costs, RBPs reduce net present cost by deferring replacements and retaining greater residual value. Sensitivity analysis identifies robust thresholds for economic viability: battery capacities above approximately 50kWh, annual driving distances below 12 150km, and incremental costs under 7%. These findings position dynamic reconfiguration as a scalable, cost-optimised architecture for next-generation EV platforms, and provide a quantitative foundation for future RBP hardware, management software, and life-cycle sustainability assessments.
