EV Arc is the World’s First Mobile (?) Solar Electric Vehicle Charger


Meet EV Arc.

EV Arc is a “unique and patent pending” solar charging station for plug-in vehicles design by Envision Solar.

What’s so unique about EV Arc?  Well, Envision Solar says that it’s the “worlds first fully autonomous, fully mobile, fully renewable electric vehicle charging station.”

The breakthrough here would be that its “mobile,” but is it?

EV Arc weighs something like 10,000 pounds, due mostly to its 22-kWh lithium-ion battery pack and its associated solar gear.  Its dimensions are 9′ by 18′.  We see no wheel attached for trailering it.  No hitch to pull it.  And no way to easily get this solar unit from point A to point B.  So, it’s not mobile as we see it.

Moving on.

EV Arc is estimated to cost around $40,000 and here are some specs:

“The 2.3kW Solar Array generates approximately 16kWhrs per day, which are stored, ready for use in the 22kWhr battery storage. Clean solar electrical generation is enhanced by Envisions proprietary and patent pending tracking solution – EnvisionTrak that causes the solar array to follow the sun as it moves across the sky.  An EV ARC will fully charge one typical EV per day or offer 1/4 charges to multiple EVs in city environments where users will park in them while having lunch, running errands or taking a meeting.”

The big advantage of EV Arc is that “the electricity provided to the EVs is 100% renewable, clean and solar powered making the EVs that charge from EV ARC 100% emissions free unlike when they charge from the grid.”   We won’t argue against that.

But it’s this “mobile” claim that keeps coming back up.  Envision Solar says this:

“Mounted on an attractive, ballasted pad, the EV ARC does not require any foundations, trenching, electrical upgrades or even a building permit. It is 100% self-contained and is delivered to the site ready to use on it’s own undercarriage.”

“Deployment time is about 5 minutes instead of several weeks for a traditional, grid tied EV charger. If the host site later prefers a different site for the charger they can simply move it.”

How?  How do we “simply move it?”  Drag it around with a toe strap?  Nudge it along with the bumper of a truck?  Maybe we’re missing something here.  Do you see a way this 10,000-pound unit is “simply” moved?

Using a forklift?, it could be lifted from the opposite side. I have seen mobile offices moved that way.

Fork lift or a small crane. Deliver a couple on a flat bed and place them w/a crane. I could see these being used at temporary events.

build the whole thing into a box truck. If clever, you do a Natural gas box truck and rig a DC quick charge off the truck engine as well. Then you have an honest mobile L2 solution with real value and flexibility.

I’d imagine it is fairly difficult to net 16 kWh from a 2.3 kW system with a 1-axis solar tracker via battery storage on most days of the years. That’s 7 solar hours, probably impossible to come close to that for 80% of the country over a year…and when many EVs require more power (October to February), for sure it would not be attainable.

Output aside, it is still an interesting concept for those who want to be truly off the grid

Put a handle on it.

Sorry, old computer joke.

$40K for a system with $2K of solar panels on it. I guess most of the money is for the batteries and structure.

“…ready to use on it’s own undercarriage.”

Well, we only have one photo to deduce what’s going on. I would guess that it has casters or rollers somewhere. You can’t make it too obvious or else it might just roll away by itself one night (with a little help)!
