スイスのエネルギーシステムモデルを拡張し、異なる消費者セグメントと充電インフラ（CI）オプションを考慮して、EV充電戦略がネットゼロ目標に与える影響を分析。2050年までにBEVシェアは39〜77%に達し、各BEVに約5kWの充電容量が必要。住宅地での夜間充電アクセスがBEV普及を12〜20%向上させ、非住宅地での公共充電が24%向上。低出力の遅い充電は家庭で費用対効果が高く、高出力の急速充電は商業地域で太陽光発電の統合を支援。政策提言を提供。

This study extends the Swiss TIMES energy system model with heterogeneous consumer segments and charging infrastructure (CI) options to analyze EV charging strategies for net-zero targets. Results show BEV share reaches 39-77% by 2050, requiring about 5 kW charging capacity per BEV. Overnight charging access in residential areas boosts BEV penetration by 12-20%, while improved public CI in non-residential areas increases uptake by 24%. Low-power slow charging is cost-effective at home, while high-power fast charging supports solar PV integration in commercial areas. Policy recommendations are provided.

📄 Abstract（原文）
A coordinated Charging Infrastructure (CI) strategy could accelerate the adoption of Battery Electric Vehicles (BEVs). Policymakers need to understand the tradeoffs between several types of CI developments. To support decision-makers, we apply the Swiss TIMES Energy system Model, which we extended with heterogeneous consumer segments with four trip types and several CI options. The novelty of this work lies in the interplay of such method advancements, representing BEV charging options with various CI types that can be accessed based on their location type at an hourly intraday temporal resolution. In explorative scenario analyses, we evaluate the effects of CI on car fleet deployment and their energy system implications in achieving net-zero CO₂ emissions in Switzerland by 2050. Our analysis shows that the BEV share makes up 39%–77% of the fleet by 2050, and each BEV needs about 5 kW total charging capacity, split into 1.6–2.6 BEVs per private charger and 18–25 BEVs per public charger. Providing overnight charging access through private home chargers or public chargers in residential areas facilitates a 12%–20% increased BEV penetration compared to the reference scenario. For consumers without private home charging, improved public CI in non-residential areas increases BEV uptake by 24%. While low-power slow CI is cost-effective at home, high-power fast CI in commercial areas supports integration of solar PV. We highlight the need for coordinated CI policies and provide a variety of policy options based on our analysis and international insights. ; ISSN:2515-7620
