Other 80A chargers?

[Cosmacelf]

Given the issues some people have had with the FCSP charging at 80A, it begs the question, are there any other good options?

First, if you don’t need to charge at 80A, then sure, dial it back down to 60A or 48A or whatever works for your driving habits, and the FCSP should be able to handle that in almost any environment. That works for most people since most people won’t drive enough in one day such that a 60A overnight charge won’t fill It up.

But for those that want/need 80A charging, are there any other good J1772 80A EVSEs out there?

I don't think there are many, since there are only a small handful of cars that can even use that speed.

The only other real option, without going to a larger commercial unit, is the Tesla Gen 2 wall charger. Tesla still sells them through their commercial sales portal as they're still the preferred destination charger unit. Their 1st and 2nd generation chargers supported up to 80A charging on a 100A circuit, as older Model S had the ability to charge at 80A and some earlier model X could do 72A. Gen 3 (current models) only support up to 48A on a 60A circuit.

I have a spare gen 1 Tesla wall charger new in box that I'd probably sell. It does 80A, but is known to be finicky with some cars and J1772 adapters, so probably not the solution anyone is looking for.

I found the below yesterday when looking at the batteries from Emporia. I know nothing about the charger or cost.

I'd suggest that few people actually figure out their NEED.

131kW battery. How many miles do you actually drive in a day, and how long is it parked for charging when you're home?

A 48amp charger, on a 60amp circuit, will deliver about 10.5kW to the truck after loss. So, to fully charge a 131kW battery would take 131/10.5 = 12.5 hours or so. I'd submit that many people are home by 7 and don't leave for 12 hours.

Let's assume that's a bad assumption. 131kW x 2mpk = 262 miles. I'd think that a very heavy user would use 200 miles a day (50,000 miles a year). 200/2/.9 for loss = 111kW needed, or 10.6 hours.

If that very heavy use case didn't allow 10.6 hours of charging, and only 8 hours, then perhaps more power would be needed, but that's going to be a tiny fraction of 1% of drivers.

I'd submit that 48amps is adequate for the vast majority of drivers.

One of the things you're not factoring in is time of use rates.

If I plug in at 7p so I can leave by 5a, I pay $.58 kw vs $.21 for those first few hours. Rough math, but that's $3.75 an hour assuming 11kw for charge rate. $7.50/day difference.

Most have a discounted rate, either after 9p, 12a, or another time, so it's beneficial to go harder but for a shorter period of time. Giggity.

True. My TOU low rate period is 16 hours long.

True. My TOU low rate period is 16 hours long.

And mine is only 6 hours long. Nonetheless, for me, that 6 hours is enough time to recover my charge 99% of the time with 48A charging.

I have 1 1/2cents p/kwh time-of-use overnight 11pm to 7am with Georgia Power, and my 30a FordMobileCharger works as my everyday charge equipment... unless you arrive on empty and you need to drive another 250 miles the very next morning, likely few ever 'need' anything more.

In addition to time-of-use considerations, some folks have multiple drivers for one vehicle. If two drivers are working opposite shifts, the truck might not at home for very many hours, so faster home charging would be appreciated. Not a common use-case certainly. Another scenario would be if you regularly visited a site 200 miles away for a few hours and wanted to be able to charge enough to get home. An 80A evse gets you about 25 miles per hour on average by my calculations. Some people have two EVs and only one evse, so the faster it can complete the better.

All this to say - some people have a need for an 80A evse, so it would be nice to have options, or at least one inexpensive and reliable one.

I believe Wattzilla still offers single and dual 80A options.

Oh right, those guys. Looks funky, looks bulletproof and are expensive. Not really appropriate IMHO for home use.

 

[The Weatherman]

You might checkout State of Charge on YouTube. This guy has tested and continues to test every mainstream unit on or coming to market.

When I was looking at chargers, it looks like all the 80 Amp chargers are made be Liteon

Here's an example. The EX-1193-1 is the telling thing
