米国のオークリッジ国立研究所(ORNL)の研究者は、電気自動車(EV)の充電器が電力グリッドの電圧低下や障害にも関わらず、より信頼性を持って動作するようにするアルゴリズムや多層通信・制御システムを開発しています。EVの普及を促進するために、充電が予測可能で安定して行われることが重要であり、これにより長距離の旅行中に充電の不安が軽減され、より多くのドライバーがEVを選択する可能性が高まります。

Abstract

This paper focuses on the development of a tool that includes an automated testbed with controls, protection, and communications integrated into a real-time system to provide a platform to generate data sets for failure modes and effects analysis. This tool establishes a value for automation of data generation for different scenarios and addresses the gap of nonexistent field data for different applications and use cases. The features of this tool can further be expanded to include multiple power electronics models, communication protocols, and scaled system architectures. This general framework was evaluated for a DC fast charger system use case to provide quantitative solution for resiliency.

Abstract

As DC fast charging electric vehicle (EV) infrastructure continues to expand, potential challenges loom. One issue is the potential for EV charger outages due to electrical grid voltage transients. Today, EV chargers are expected to disconnect under a severe voltage sag (below 70%) which reduces electric vehicle charging infrastructure resilience. This work proposes a droop-control solution to ride-through voltage sags and maintain operation. The control solution is presented in a controller hardware in the loop platform.
