Smart Charging and Consumer Behavior in the United States

The document examines the necessity of transitioning from unmanaged electric vehicle (EV) charging to smart charging (VGI) to prevent grid overloads and better align with solar generation. Based on a survey of Honda EV owners in the US, it finds high interest in VGI programs driven by environmental and financial motives, though significant concerns persist regarding data privacy and battery life, particularly among BIPOC, lower-income, and female respondents.

• The transportation sector is the primary source of greenhouse gas emissions in the United States, representing nearly one-third of 2020 emissions, while EVs typically produce one-half to one-third of the emissions per mile compared to traditional vehicles.
• Unmanaged charging, where power output is constant from the moment of plugging in, creates grid risks because it typically occurs in the evenings during peak residential demand and is misaligned with peak solar generation during the middle of the day.
• Smart charging, or vehicle-grid integration (VGI), can mitigate grid costs and impacts by controlling the location, direction of power flow, power output, and timing of charging, which helps avoid infrastructure upgrades and improves grid stability.
• Survey results show that 95% of respondents are interested in VGI programs for financial, energy-saving, and environmental reasons, although 94% express concerns, most notably regarding charge readiness, battery life, and data privacy.
• Concerns regarding server control, battery life, and data privacy are generally higher among female respondents, lower-income individuals, and Black, Indigenous, and people of color (BIPOC).
• Between 80% and 89% of respondents are interested in buying an EV capable of VGI if offered annual incentives ranging from $300 for unidirectional programs to $1,000 for bidirectional programs.
