Ipsos Global study finds three barriers to consumer adoption of EVs: cost, range, charging sites

Green Car Congress

Todd Markusic, Vice President of Mobility at Ipsos, said the Ipsos Global Mobility Navigator Syndicated Study discovered there are three main barriers towards BEV ownership for consumers: overall cost, range and charging location stations. However, we see once that price point exceeds 20%, consideration in the BEV option drops considerably.
