The electric vehicle (EV) industry grapples with range anxiety and long charging times, but beneath the surface, a more critical issue emerges: the unpreparedness of American homes for safe EV charging. A recent survey by the Electrical Safety Foundation (ESFI) sheds light on the challenges.

Over 50 percent of US homes lack electrical systems capable of handling the continuous load that EV charging demands, according to the ESFI report. This goes beyond the familiar concerns of range anxiety and highlights the need for a proportional upgrade of the electricity grid and ensuring the safety of home electrical systems.

Surveying over 380 respondents, ESFI found that 63 percent scheduled a home inspection before installing electric vehicle supply equipment (EVSE). Astonishingly, 54 percent required an electrical panel upgrade to accommodate EV charging needs. While 75 percent of EV owners reported no charging issues, eight percent experienced electrical shocks.

To ensure safety, experts recommend using manufacturer-approved and certified charging equipment adhering to standards from UL, ETL, TUV, or CSA. InsideEVs emphasizes checking for a printed label on the unit.

Charging an EV involves substantial current flow over sustained periods, causing circuits to heat up. Older homes may struggle to handle this load safely. ESFI President Brett Brenner advises consumers to have a qualified electrician assess their homes before purchasing or installing EVSE.

Using non-approved charging equipment can bypass safety features, exposing owners to shocks, fires, and potential damage to an EV’s battery. John DeBoer, head of Siemens eMobility in North America, underscores the importance of purchasing certified equipment from trusted sources.

While 96 percent of respondents were satisfied with their home charger installation, 20 percent had to replace their charging equipment. Surprisingly, one-third did not receive charging information before purchasing EVs, highlighting the need for qualified experts to inspect home electrical systems.

It’s crucial to note that the survey’s 387 respondents owned 2020 model year EVs from various brands, and results may not represent a nationwide trend. Regional demographics could influence responses, with EV owners in California potentially differing from those in North Dakota. As we delve further into the EV revolution, addressing these home charging challenges becomes paramount for a seamless transition to electric mobility.
