portable charger

[ceb58]

Need an opinion on a mobile solar car charging station. This unit is pulled into place on a trailer with hydraulic lifts. When in place it is lowered to the ground and unhooked from the trailer and the trailer is pulled away leaving the charging station sitting on the ground. The station has receptacles for plugging the charging cables into. A 120v drop cord is ran to this unit to make sure that the batteries never go below 25% if there is too much cloud cover to fully charge the batteries. My thoughts are that this unit must comply with 690.47 A ( 2017) in having a grounding electrode system installed. The tech's from the company that make these units are saying that since it is not grid tied it doesn't need the grounding electrodes installed. What are your thoughts?

It sounds similar to a portable generator, except for the 120v input, but still shouldn't need earthing.

I sure would like to see the specs on this unit. Just off the top of my head I can't imagine the math on this would charge many cars.

I very seldom see anybody at a charging station in the suburbs and small towns, so it might just be efficient enough for the few cars that do pull up.

If it is truly mobile and moved often enough (and not just being called that while being left in one location indefinitely), then I daresay the NEC has no jurisdiction over it. Or, to the extent it would, I agree with Larry.

(Also what would grounding it help, anyway?)

Absolutely agree that this isn’t under the purview of the NEC.

Is this like the Tesla holiday chargers they bring in to high use sites?

Tesla may just have figured out the perfect way to bolster its charging infrastructure during the holidays, a time when more drivers are taking long trips and relying on the company’s Supercharger Network. Based on images and videos captured by the Tesla community, it appears that the electric...
