Some may find this interesting if planning to purchase the Fisker + Wallbox Home EV Charger. Seems to charge slower than I had originally thought with this specific charger. I also received a $1,299 quote for installation using COIL (the Wallbox subsidiary). That's about the same cost I paid for the Tesla Wall Connector to be installed last year. 

https://fiskerati.com/fisker-ocean/new-fisker-ocean-home-ev-charging-details-emerge/

Fisker published new information to its website about home charging solutions, but we still don’t know anything about pricing. However, we do know how long it will take to charge your Fisker Ocean with the Pulsar Plus home charger. According to Fisker, “The Fisker Wallbox home charger will add an estimated 20-30 miles / 32-48 km of range per hour depending on your battery and country. This is enough to fully charge overnight for most owners.”

@seancallahan Sean, I just got a quote from a “Certified Tesla Wall Connector Installer” to convert my NEMA 14-50 to the wall connector… they wanted $2,750!!!  It is a 30-60 minute job to remove my current outlet and connect those wires to the new charger’s mounting plate. 
Worst part was that they claimed it would not be warrantied if anyone other than a certified Tesla installer did it—I called BS and told them to read the warranty. 
anyway… I plan to add the Tesla connector since it is 60 amp hard wired and use the new Lectron Tesla to J1772 connector that is 48 amp rated—good option for us as we will have 2 Oceans and a Tesla in the fam.

I think the Wallbox is good for 40 watt output on a 50 amp circui vs the Tesla Wall Connector with 60 amp circuit and adapter is good for 48. 
edit… i see Wallbox has both 40 and 48 amp output options. So, the miles/hour of charge just quoted seems a little low, especially compared to the Tesla Model Y gaining 44 mile/hour with the Tesla Wall Connector.

@fiskerdu Wow, that quote is ridiculous. You may want to reach out to COIL for a quote as I saw they offer Tesla Wall Connector installation too.

@seancallahan I had all the hard/expensive work done last September running the wire from the service panel and creating the 14-50 outlet… so, now after getting 2 quotes over $2k, I am just planning on shutting off the breaker, unscrewing the outlet from the wall and screwing those 3 wires to the Tesla wall connector (end capping the neutral). I am tempted to time myself and extrapolate it to an hourly rate based on the $2,750 quote.

@fiskerdu Sounds like a fun project as long as you use a voltage tester to make sure you don't get zapped! 😆

@seancallahan The key to that quote is "cost includes installation within 15 feet of the panel."  Unless your panel is right next to your garage, 15' is not much.  Our panel is on the opposite side of the house from our garage, our conduit is about 70' so the quote would have been an additional $1,500.

Excellent point. Thanks for calling that out.

I replaced a Tesla HPWC with a Wallbox unit last year.  Did it on my own - took less than half hour. Easier than replacing a light switch.  The hardest part was the holes from the HPWC didn't line up so had to drill new  holes for the wallplate.

@ttrinchi Impressive! I'm always afraid of getting electrocuted playing with the electric panel even with all the breakers off. Where we live, we don't have access to the main power switch as its locked in a cabinet, rather just the electric panel inside our condo. I could see myself replacing the charging unit if it fails since I won't need to do anything other than switch off the breakers. However, I would still use a voltage tester to be double safe. Ha ha!

@seancallahan I'm sure a 240V 60A live wire would just give you a minor shock 🙂.  Switching out the wall unit was a lot less scary than replacing the 12V battery in the Tesla (not so much for the 12V battery but the 400V HV battery that is attached to it.)

 “20-30mi/hour charging”. Let’s see…340 mile range…math not being my best subject, but if you coast it home and need to charge it to 100% you’re talking anywhere from 11-15 hours to charge your car. Dang. This will be my first electric vehicle, but that sure seems slow.

 “20-30mi/hour charging”. Let’s see…340 mile range…math not being my best subject, but if you coast it home and need to charge it to 100% you’re talking anywhere from 11-15 hours to charge your car. Dang. This will be my first electric vehicle, but that sure seems slow. 

A few things to help:

A home charger can only produce a certain amount of power (7.7 kw for a 40 amp circuit, 9.6 for a NEMA 14-50 50 amp, 11.5 kw for a 60 amp direct circuit). So any vehicle will get a maximum energy into the battery of 7kwh per hour (40 amp), 8.5 kwh per hour (14-50), or 10.5 kwh (60 amp) after charging losses (+/- someone can correct charging losses if not quite right). This is described as follows when you are buying a home charging setup:

  • 32 Amp Charger (means 7.7 kw, 40 amp circuit)
  • 40 Amp Charger (means 9.6 kw, 50 amp circuit)
  • 48 Amp Charger (means 11.5 kw, 60 amp circuit)

Everything else is about vehicle efficiency. A small, highly efficient vehicle like a Tesla Model 3 which consumes and EPA rated 0.258 kw per mile will add on a NEMA 14-50 around 32-33 miles per hour (8.5/.258). An F150 Lightning chews through 0.479 kwh per mile so it will only add 17-18 miles per hour on that same outlet. 

The 20-30 miles / hour number is giving us a hint about vehicle efficiency, but I expect the Ocean to come in around 0.34 (reference, the BMW iX is 0.4 the Model Y performance is 0.305). Conveniently, that would be around 20 miles on a 40 amp circuit, 25 miles per hour on a 14-50 plug and 31 miles on a 60 amp wallbox. Or 20-30 miles per hour.

A few things to help (part 2):

  • You never coast home. You will always arrive with 10% charge. 
  • You normally charge to 80% not 100% unless you are headed for a road trip
  • If you need a faster charge you stop at the DCFC

Final thought on this: as will be obvious, if the 0.34 is about right based on the charging speed data above, then the battery size = 102kwh usable and ~ 110kwh total.

Why are you using 300 mile range?  based on 340 Wh/mile rated, I calculated 119 kWh useable battery for One/Extreme (ignoring the fact that rated Wh/mile efficiency includes charging losses).
