One unanswered question about the shift to electric vehicles is how we’ll bring EV charging to existing parking infrastructure. Between permitting delays and shortages of qualified workers, charger installation is often a slow endeavor. But that doesn’t mean people aren’t trying to find solutions.

Dallas-Fort Worth International Airport, for example, is testing a number of ideas over the next few months. One of them is a new mobile DC fast-charger from Lightning eMotors, which will be put through its paces June 19–23 charging EVs for staff and customers.

Regular readers might be feeling a sense of deja vu, as we just reported on a mobile charger being tested at DFW in the coming weeks. In that case, it was a robot charger on wheels called Ziggy, which can shuttle between EVs in a parking lot.
