Help with home ev charger

[SergeyIndy]

I have the simplest setup to get you a baseline, then you can complicate from there to read many helpful threads. I have Emporia based on the State of Charge guy recommending as he likes it best. I have it hardwired (inside the wall) for clean look direct to the panel and next to the panel and I get max charge possible for the charger and Taycan (not having 19.2kW option and rare use case for needing it) from 60Amp with picture below. The cost for install was $595 then cost of the charger $399 before taxes. Benefits: quick install, cost effective, clean look, max charge rate, minimal wires, but some may say not as flexible without having a socket to plug another EVSE but for me other benefits outweigh that. Good luck and do not worry, I was in the same gosh what to do mode and it is much simpler than it appears.

My setup is in green and if you do a socket to plug your EVSE in then you would be a yellow.
Again, this is saying without 19.2kW option and 100Amp circuit which will give you values above the green line and rare case for needing it. However, there is nothing wrong with anything below the yellow as long as you have enough time at night to get it charged to the level that you want.

Hello,

Just bought a taycan and getting quotes to get one installed in my garage. I know nothing when it comes to electrical so looking for some guidance on what I need as far as what charger to get, make sure can handle level 2, whether it should be hard wired, amps, price ect...

Here is the first quote I have...

"Wire and install a dedicated 50am circuit from the electrical panels in the basement to a nema 14-50 in the garage (30' total run/dropped ceiling). Provide and install breaker, wire, 14-50 receptacle, mount charger, and terminate all electrical terminations"

Trying to charge $895 (seems high but getting other quotes)

Thanks in advance.

Very reasonable

Awesome, thanks! Love this car ?

Should I request hard wired 60amp?

I had a hardwired 60A installed to accommodate the JuiceBox 48A charger. Electrician charged me $700. Charger works perfectly.

Just an added note re listed 11.5Kw charging rate on a 60A hardwired install in above posts - yes that is max output on a hardwired 60/48 setup but be aware you'll never see this in the car when charging (in case you see this and are scratching your head !) i.e. typically will get ca 10.5Kw in the car - due to losses related to cable heat/length, EVSE components etc. Same for all makes.

I had a hardwired ChargePoint HomeFlex installed in Oct 2021 that has been flawless now for 1.5 years - I also had an additional Hubbell 50/40 plug installed (above Mini sign) as I had the extra capacity in my garage (I did not spec the 19.2 in my car) - gives me options, not only for our 2nd EV which hopefully will arrive in a year or so but also if others visit provides an option for them to use their own portable charger.

if possible I highly recommend a 60 amp hardwired EVSE + NEMA 14-50/6-50 (these days I prefer the 6-50 socket and keep a 6-50 --> 14-50 $20 adatper on hand) - you can install both even if you do not have capacity - since the 14-50/6-50 will be lightly/never used - you can install it and just make sure you don't use both the 14-50/6-50 & 60 amp EVSE at the same time (unless you have the capacity to do so)

for the future multi-ev household I recommend either the Enhpase-Clippercreek/Wallbox/Tesla EVSE's - since I know for a fact those 3 EVSE's offer "load sharing" - i.e. you can run TWO EVSE's charging 2 (or more) EV's at the same time and they will load share the assigned circuit capacity to avoid overloading the circuit's breaker - it makes owning mutiple EV's soooo much nicer to just plug them both in and let them charge and share the available capacity.

great setup on garage BTW @ciaranob - really really well done!

Both hardwire connection and receptacle on same supply circuit/breaker, or on separate supply circuits/breakers?

Both hardwire connection and receptacle on same supply circuit/breaker, or on separate supply circuits/breakers?

still on separate breaker…if you're planning an EVSE + NEMA 14-50/6-50 would be my recommendation

• one breaker in the main panel feeding a subpanel (60/80/100/125/150 based on capacity available)
• "n" breakers in the subpanel
  • 60 amp breaker for the EVSE #1
  • 50 amp breaker for the NEMA socket
  • 60 amp breaker for the EVSE #2 (load shared configured to "match" main panel breaker size)

Example: 2 x Tesla J-1772 Wall Chargers (each 48 amp max) power-shared/configured to "share" 64 amp total charging capacity from an 80 amp "main panel" breaker…this would allow a single EV to charge at a max 48 amp rate on either EVSE, but combine capacity of "both" EVSE's being used at once would split 64 amps total charging capacity (80 amp main panel breaker feeding the garage subpanel). This is a pretty ideal scenario - 32 amp for dual EV charging, and 48 amp for any single EV charging - and NEMA 14-50/6-50 to be used solo for what ever reason (i.e. don't use the NEMA socket and either of the EVSE's at the same time).

that way they are still dedicated circuits, but protected by the main 60/80 amp breaker in the main panel...so you can't use both at one (at full capacity) - but as long as you do not use both at once you can use either the EVSE _OR_ the NEMA socket.

subpanel will also make it super easy to add your future (2nd or 3rd) EVSE - that can share load - and you adjust the 2nd and 3rd EVSE to "know" they are all sharing a 60/80 amp breaker (48/64 amp total capacity).

I'm using two Autel Maxicharge EVSEs. One is hardwired using a 60 amp breaker and another one is installed with a NEMA 14-50 using a Hubbell receptacle.

Ended up with two Autel units while waiting for ChargePoint to replace my ChargePoint Home Flex under warranty (dead WiFi module). ChargePoint finally sent me a new unit about 2 weeks after I installed the second Autel.

I've tried 4 different EVSEs (Schneider, Tesla, ChargePoint and Autel) and my favorite so far is the Tesla Wall Connector unit. I may remove the hardwired Autel unit and re-install the Tesla Wall Connector. The Tesla unit was the most reliable for me with no issues and was rock solid. I've had minor issues with the ChargePoint and Autel EVSEs. I also had a Clipper Creek J1772 plug (public charging station) get stuck in a Chevy Volt and so I never considered them for a home EVSE.

+1 for Tesla EVSE's - 12+ years Wall Charger gen1, multiple gen2 wall chargers, and now mixed NACS+2xJ-1772 wall chargers load shared - zero issues.

Quote is very fair as wire cost for 30ft run is expensive. I just paid $1150 in South Carolina for the same and I supplied the NEMA 14-50R receptacle.

Some simple notes:

1- A good NEMA 14-50R receptacle (Porsche and others recommend Hubbell) will cost around $100. you can buy the receptacle from Amazon here's a link.
https://www.amazon.com/dp/B000J15QW2?psc=1&ref=ppx_yo2ov_dt_b_product_details

2-You can buy any good 40AMP plug in (not hard wired) wall mount charger such as WallBox, JuiceBox and others. I have a WallBox

3- You then have the flexibility of using the wall mount unit daily and having your porsche supplied unit as a backup.

It sounds complicated and confusing at first but really quite simple when you get used to it.

This is what the electrician said when I asked for 60amp hardwired woth Hubbell

"The 14-50 receptacle that your charger requires is only rated up to 50amps. In order to go up to 60, a 14-60 receptacle would be required, however the cord end on your charger wouldn’t fit that receptacle. Chargers at 60amps or above are usually always hardwired for this reason. In short, we would be forced to stick with the 50amp circuit and 14-50 receptacle. I hope this helps clarify. "

Advice?

I don't think that was the advice; it's _either_ 14-50 plug-in EVSE w/ Hubbell receptacle, _or_ hardwired 14-60 EVSE (no plug).

Advice?

good advice but not as clear as it could be.

you can have a 50 amp EVSE (40 amp charge rate) - which can be hardwired _OR_ plug based (NEMA 14-50/6-50) - 50 amp breaker - 9.6 kW max charge rate (240V @ 40 amps)

or you can have a 60/70/80/100 amp EVSE which _MUST_ be hardwired - once an EVSE is more than 50 amps the only option is hardwired.

no one makes a NEMA 14-60 plug based EVSE…

if you can afford it I would get a 60 amp EVSE (48 amp charge rate - 11 kW - 240V @ 48 amps) - and have it hardwired (because that's the only option)

if you want (optional) you can also have them install a NEMA 14-50/6-50 socket as an alternative/backup to the hardwired EVSE.

but you can have a 60 amp EVSE if you choose to hardwire and your electrician says your main panel can handle the 60 amp breaker.

clear?

if you can stomach the cost I would do the following:

• 80 amp breaker added to the main panel (if you panel can handle the extra capacity)
• the new 80 amp breaker feeds a new subpanel in the garage (at least 8 blank breakers)
• in the new garage subpanel install a 60 amp breaker
  • install a 60 amp EVSE hardwired to the new 60 amp breaker in the subpanel
• in the new garage subpanel install a 50 amp breaker
  • install a Hubble NEMA 14-50/6-50 outlet off of this new 50 amp breaker
• tell the electrician you never intend to use them both at once
  • (truth and common- the outlet will be rarely used, and all you need to do is not use EVSE and the outlet at the same time)
• future: when it comes time for the 2nd EV or Hybrid and a 2nd EVSE - adding another 60 amp breaker for the 2nd EVSE in the subpanel will be trivial - and you can configure the two EVSE's to "share" the 80 amp breaker load from the 80 amp breaker in the main panel.
  • you'll thank me later.

but you can also do just a 60 amp EVSE, hardwired, call it day and be very very happy for many many years.

How much do you think it would cost for your suggestion and how much do you think it would cost having him get it to where I do 60amp hardwired? I know it varies...just trying to get an idea. Don't expect it to be super accurate.

What's the disadvantage to doing it how the electrican suggested? Slower charge times (how big of a difference)?

And thanks for the help. I'm really illiterate when it comes to electrical and would be lost without everyone's help in here ?
