Jeremy Michalek, professor of engineering and public policy, Carnegie Mellon University in the US, says that increasing charger availability will help EV adoption and gasoline savings, though he notes that in markets such as the US where most users can charge EVs at home, this may not be so cost effective. ABB has integrated cloud connectivity and services into its chargers since it began making them in the early 2010s to address these challenges  For example, to allow users to quickly access and pay for charging services, ABB allows network operators to install mobile and web applications for drivers to be authorised to use the device.  In addition to seamless payments, there are numerous ways that cloud services can make EV charging more attractive, say experts.
