Previous studies with different charging infrastructure scenarios have mostly focused on early adopters and do not conceptualize infrastructure as a tool for charging control 9, 10, 26, 34, 37, 38. However, most studies have limited scenarios regarding charging infrastructure access, use centrally optimized controls rather than site by site, rate schedule-driven optimizations or focus on current grid resources and conditions, and few include grid storage and calculate emissions (Supplementary Note 1). Numerous previous studies have used charging controls to improve the grid impact and costs of EVs 8, 9, 25, 26, 28, 29, 30, 31, 32, 33, 34, 35, 36.

Assuming the use of charging infrastructure will continue to match early-adopter behaviour would misrepresent future drivers’ options and could miss valuable opportunities for households, utilities and the regulator.Įxisting approaches to modelling large-scale charging demand impute charging decisions based on early-adopter behaviours or modeller assumptions about driver behaviour 9, 10, 25, 26, 27.
Lower-income households, renters and residents of apartment buildings or multi-unit dwellings (MUDs), meanwhile, are all less likely to have access to home charging 12, 13, 16, 17, 22, 23 despite targeted subsidies 24.
Wealthy residents of single family homes (SFHs) are over-represented among early EV adopters and are likely to have access to home charging 21.

The charging infrastructure network’s design and geography, in turn, change the choices available to drivers and reshape system-wide charging demand by changing the charging location and time of day (for example, from overnight if charging at home to midday if charging while at work).Ĭharging access is key to avoiding charging inconvenience, which can be a barrier to both adoption and continued use of EVs 16, 17, 18, 19, 20. Charging controls, also called smart or managed charging, reshape demand by delaying charging to a preset time or by modulating the power delivered throughout a vehicle’s charging session in response to electricity prices. Adding charging controls and changing the landscape of charging infrastructure by increasing or decreasing the availability of different charging options represent powerful tools to reshape charging to improve grid impacts at future, deep levels of EV adoption. Driver behaviour is highly heterogeneous and stochastic 12, 13, 14, 15, 16 where, when and how often drivers choose to plug-in determines their load shape and demand on the grid. While the implications of transportation electrification for the grid have been studied at low, near-term levels of adoption, identifying and mitigating system consequences at deep levels of EV adoption has remained a critical challenge as it requires models that capture the diverse behaviours and conditions of future drivers 11.Ĭharging infrastructure, controls and drivers’ behaviour have implications for grid operations, making the long-term planning to support daily charging demand under high electrification scenarios challenging. EV charging couples transportation to the grid, yet the two sectors’ transformations are largely uncoordinated, despite their shared objectives of lowering emissions 4, 5, 6, 7, 8, 9, 10. Industry analysts forecast that the number of light-duty EVs and their charging plugs will multiply to over 300 million and 175 million, respectively, worldwide by 2035, an order of magnitude increase when compared with 2021 3. The use of electric vehicles (EVs), coupled with an electricity grid that is decarbonizing, can help the United States achieve emissions reduction targets 1, 2. Our results urge policymakers to reflect generation-level impacts in utility rates and deploy charging infrastructure that promotes a shift from home to daytime charging. Shifting instead to uncontrolled, daytime charging can reduce storage requirements, excess non-fossil fuel generation, ramping and emissions. Locally optimized controls and high home charging can strain the grid.

We find that peak net electricity demand increases by up to 25% with forecast adoption and by 50% in a stress test with full electrification. We study charging control and infrastructure build-out as critical factors shaping charging load and evaluate grid impact under rapid electric vehicle adoption with a detailed economic dispatch model of 2035 generation. We present a data-driven, realistic model of charging demand that captures the diverse charging behaviours of future adopters in the US Western Interconnection. Electric vehicles will contribute to emissions reductions in the United States, but their charging may challenge electricity grid operations.
