Presentation Description

Rapid decarbonization of the transportation sector is critical to achieve net-zero emissions by 2050. While the share of light duty Plug-in Electric Vehicles (PEVs) on road is steadily growing, one major barrier of current PEV growth is the deployment of required charging infrastructure, especially public charging stations such as retail and destination Level 2 (L2) and DC Fast Charger (DCFC). In light of the practical grid infrastructure constraints that may hinder the deployment of public charging infrastructure, many innovative charging solutions have emerged to reduce costs and delays associated with grid upgrades. This study focuses on innovative charging approaches that integrate with distributed energy resources (DERs), such as battery energy storage (BES) and solar photovoltaics (PV) energy generation. We evaluate their potential to reduce costs and delays associated with distribution grid upgrades by conducting a technoeconomic analysis using Argonne’s Battery Electric Vehicle Analysis Model (HEVISAM). We find that cost of electricity and port utilization rate are the key drivers of the station levelized cost of charging (LCOC) across all charging scenarios. Moreover, we estimate that a DCFC station integrated with BES can lower station peak load by 60-90% and potentially reduce LCOC by up to 40%. Public L2 charging powered entirely by off-grid solar PV can achieve cost-parity with current tax incentives and projected reductions in battery and PV costs, while offering significant deployment rate and emissions benefits. Despite higher upfront capital costs, our analysis shows that BES and PV integration can be cost-effective charging solutions in the long run to accelerate the deployment of public charging infrastructure nationwide.
