Recommendations for light-duty commercial EVSEs

Wed Aug 30, 2017 11:01 am

My company is planning on installing another 20 EVSEs on campus and our facilities folks asked for recommendations. Our first dozen EVSEs were all Eaton units, but they got out of the commercial EVSE business when we went to add more. The next two dozen they bought were Schneider EV230WSRs, but Schneider just announced they are also getting out of the commercial EVSE business. Hence the need for a recommendation for this next round.

Our usage typically has the EVSE shared with 2 parking spots and used by 3-4 cars each day, with between 5-8 hours usage over a workday. The mix of cars is just about everything you can imagine. Lots of LEAFs and Volts. The 5th Bolt just showed up on campus. Half a dozen Teslas (and half a dozen people with reservations on a 3). A smattering of PIPs and Prius Primes. 1 or two each of the eGolf, Merc B, Ford Focus, Soul EV, etc. I think we have well over 50 plug-in vehicles.

FWIW: the Eatons have been rather unreliable (one fails every few months). The Schneider units seem to be holding up fine, although more than half of them are not being used yet as they are at another site that is still under construction.

Facilities is looking for 30A/240V units that can be wall mounted in a parking garage, are appropriate for light-duty commercial use, and require no service contract (no ChargePoint, no RFID, etc). They are not interested in networked units at all (no WiFi is available). They want something reliable from an established manufacturer that can be installed and will just work.

Minor update: they are looking for units that can be hardwired.

Does your campus have EE students? If so, have them assembly a bunch of OpenEVSE's. As an incentive, whomever's fails within a month has to redo their project or fail their class!

We're a business. For this we want "off the shelf" and "just works". Is there a commercially supported OpenEVSE vendor?

They are already investigating Clipper Creek and Bosch stations.

I've seen CC's used in a few small installations but personally, consider their design to be more residential.
I'd think something more like this Siemens wall mount to look more like a typical commercial installation, and includes a nice plug to hold the j1772 end when not in use.
https://www.amazon.com/Siemens-VC30GRYU ... HZYQF3MQ7W
GE also makes a wall mount unit and at the $399 they were when I got mine, I'd consider them a good deal but at the $500+ they not regularly sell on Amazon to be somewhat over priced. The GE also lacks a holder for the j1772 end although myself and many others have purchased a separate female j1772 end and mounted it to the front cover of the GE, to hold the end when not in use, about $10 from Amazon.
Home Depot still shows the GE for $399, not sure if it's available or not. The Siemens is nice in that it has a power button and ability to use a shutoff timer, the GE is very basic and only has a power/charge light.

The Bosch has been around for years, a bit higher priced than the others I mentioned but still within reason I'd think, and has a j1772 holder.

The CC design being more residential was in fact the concern the facilities group had on their units.

GE's EVSE business was apparently just bought by ChargePoint and those units will soon be no longer available.

The CC units are simple and have a 3 year warranty (although it may not apply in this case). I think they are rugged enough. Just take more care mounting them, as the mounting holes are in plastic.

The most offensive, tasteless phrase in use here is "Pulled the trigger." I no longer respond to posts that use it.

okay, how about emotorwerks? https://emotorwerks.com/store/commercia ... vse-bundle

They've been around for quite a while. Maybe ask if they'd be willing to make their european EVSE available for commercial installations stateside? https://emotorwerks.com/products/chargi ... juicetower

I believe Wattzilla is producing several varieties of rugged UL-certified EVSE units based on the OpenEVSE project. Looks like everything from a portable cable to a four-head 80A pedestal. They have a trade-in program for older EVSEs as well.

So the challenge is to have a cord that can be changed as they get damaged, are UL listed for safety and law suits. The e motor works are nice and can be regulated for shared circuits and it is easy to add more EVSE later with out adding circuits. E works has data tracking and controls for management. the group I have, work well for us. At times the network needs to be worked on for shared EVES on one circuit. The juice boxes stopped the fire drill at lunch of swapping EV cars around. We have a 50 Amp feed with 4 shared EVES, most days all cars get a full charge and most workers like to not have to move the cars at lunch. We were able to add more EVES with out having to add power and wiring. a shared EVSE is helpful imho..
