Electric Vehicle Recharge Time, Reliability, and
Interoperability EPR2022028
As more consumers and operators adopt electric vehicles (EVs) as personal and fleet vehicles,
questions regarding recharge time, reliability, and interoperability of EV supply equipment
and charging systems currently in use across North America and Europe remain. The current lack
of understanding has led to consumer anxiety and, in some cases, inadvertent abuse and mishandling
of electric supply equipment.
Electric Vehicle Recharge Time, Reliability, and Interoperability navigates issues such as charging
equipment reliability; the complexity Interoperability concerning charging networks, EVs, and payment
systems; various public and private charging network issues; and lagging regulations and standards.
While many challenges need to be addressed, this report also identifies the improvements made since
early adoption of EV charging technology as well as ongoing efforts to improve it further.
