A Quarter of US EV Drivers Skip Electricians to Install Their Own High-Voltage Home Charging Stations

Surprising finding from PlugShare Research based on a study of 3,534 US EV drivers

El Segundo | Oct 21, 2020

A new in-depth report from PlugShare Research found that 25.5% of electric vehicle (EV) drivers who install “Level 2” high-voltage 208-240V charging stations at home actually tackle the job on their own, rather than using a professional installer. Where typical homeowners might shy away from DIY home electrical work – especially 208-240V tasks – surprisingly large numbers of EV drivers feel self-confident enough to perform these jobs by themselves.

Most of the 1.3MM+ EVs in the US are charged at Level 2 home stations. Installation commonly ranges from hardwiring stations directly to the home electrical system, or installing a 208-240V outlet to a wall or post. It can require installers to modify their electrical panels, run wire and conduit, and even excavate.

“Projects that use higher-voltages, such as 208-240V Level 2 charging stations, are well outside the average person’s comfort zone”, said PlugShare’s Chief Strategy Officer, Norman Hajjar. “But this group is very different. Over 96% of these same drivers have also installed lighting, wall switches, or power outlets at home, so they’re unusually secure with their home electrical know-how”, he added.

Interestingly, while these “DIYers” trust their own skills, they are much more cautious when it comes to encouraging others to give it a try: over 47% disagree that DIY installation is safe to perform for the typical EV driver. But for those who do, there’s a financial benefit: self-installers estimate saving an average of $698 by doing their own work.

The findings come from a just-published PlugShare report, Electric Vehicle Home Charging Station Installation in the United States. Prepared for automakers, utilities, and charging equipment makers, the 27-page report takes a detailed look at the installation process, both for professional installers and “self-installers”, complete with analysis and 46 different data tables. It includes insights from 3524 drivers from PlugShare’s proprietary PlugInsights panel of over 63,000 drivers, the world’s largest.
