I am getting ready to install a level 2 home charger in my garage, so that I can charge my new 2020 Bolt EV Premier overnight.
I was thinking of ordering a Clipper Creek HCS - 40, as soon as I confirm with the electrician that the line from the house to the garage can handle 40 Amps. However, I see that Electrify America sells a home charging unit for $449 ( the HCS - 40 is $565 )
Does anyone have any experience with either of these 2 units ? Anyone know why the Clipper Creek unit is so much more expensive ? Thanks to all. Jim
I tried to sort through the myriad EVSE options and settled on a ClipperCreek HCS-50P to hopefully get a little overkill (40A charge possible for a little future-proofing and maybe some slightly “heavier” build quality). The “P” model comes with a NEMA 14-50 plug on a short cable out of the bottom of the unit, so I mounted it sideways to accommodate mounting the receptacle right-side-up for other EVSE or appliances, rather than an upside-down receptacle mounting for the Clipper Creek. I could take the HCS-50P on the road, if appropriate (local electrical supply house owner reminded me that the NEMA 14-50 receptacle is ubiquitous at campgrounds, trailer parks, and such). The ClipperCreek is US designed and mostly US built, they’ve been building EV charging equip probably as long as anyone, their boards are in a lot of other company’s equipment, their equip is safety certified or listed, and these units have a 3yr warranty...some of the reasons for the higher price. The ClipperCreek will auto restart charge in case of most power outages or minor faults. It doesn’t have the WiFi bells & whistles, but all I wanted was a solid, reliable, safe option. The car can start/stop, and delay/program start a charge. I don’t want anything else (and I have no financial interest in any of these companies).
I also bought (you might consider) a Tesla Gen 2 Mobile Connector Bundle (around $275), a few different plug-in adapters (about $35ea, or a whole set is around $220), and a TeslaTap (around $200), all of which allows 120V through 240V charging up to 32A and adapts the Tesla proprietary plug to a J1772. Additionally, the TeslaTap allows use of (level 2) Tesla destination chargers if a J1772 charger isn’t available. All-in-all, a pretty comprehensive charging option when traveling. I leave the Chevy OEM charger at home. I hope to recoup some of the extra costs by submitting the appropriate tax form to take advantage of tax incentives for EVSE purchase/installation.
Finally, many EVSE units have GFCI circuitry built-in. I was concerned about having a GFCI/AFCI on the supply receptacle or breaker because of the possibility of nuisance “tripping,” So I installed a EPD-type (Equipment Protection Device) breaker which has a higher trigger threshold (30ma trigger vs 5ma trigger for GFCI) to provide a level of protection (for personnel and equipment) and still minimize conflicts and headaches due to interaction with the built-in GFCI circuit. Always defer any equipment and installation decisions to a qualified electrician and applicable building codes. Good Luck.
