When we started driving cars and trucks the nations of the world couldn’t agree on which side of the road to drive on.
This has been replicated with electric cars, there are a couple of different charging couplings out there and that means not every EV can be charged (easily) at every charging point.
To try and head off a similar issue with electrically-propelled heavy vehicles, the Society of Automotive Engineers (SAE) has been working on an industry standard charging coupling.
The single vehicle charging coupler solution (dubbed the J3068) was developed by an international committee formed by the SAE and will cover three-phase and single-phase AC and DC charging.
Jim McLaughlin is a retired Mack Trucks electrical engineer in the U.S., he’s told truckinginfo.com the new standard should help speed the introduction of electric trucks and buses and charging infrastructure.
“The goals of J3068 include bringing a proven, mass produced three-phase charging coupler (to North America), and establishing a low-cost, reliable communication and control protocol for AC with inherently high interoperability”
