Help with home ev charger

[daveo4EV]

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 ?

60 amp hardwired vs. 50 amp NEMA should be trivial incremental cost but a bit more (thicker wire is required for 60 amps vs. 50 amps, more copper = more expense) - unless your main panel has to be upgraded because of the 60 amp breaker - it's either no big deal to move to 60 amps vs. 50 - or it is a big deal in which case you skip it. (note the 60 amp hardwired option saves the $100 parts cost of the hubble socket so it could be push-pull in terms of cost)

moving to a 60 amp hardwired install requires buying a non-Porsche EVSE - where as the NEMA approach can use the included PMC+/PMCC

60 amp EVSE will charge taycan 20% faster than 50 amps EVSE

a charging session that takes 3 hours with NEMA 14-50 EVSE will take 2.5 hours with 60 amp EVSE - a full charge from 3% to 100% will take 11 hours with a 50 amp EVSE, it will take 9 hours with a 60 amp EVSE…some people care, some people don't - most of the time it doesn't matter how long it takes to charge because eitehr way it's still done by 6 or 7 amp according to schedule.

the proposed 80 amp breaker + subpanel +++++ could be twice as much - but longer term will be cheaper/easier/faster because it will make the 2nd EVSE easier/faster/trivial and could avoid a permit and a future expensive electrician visit to upgrade the setup to handle a 2nd EVSE - but it will be more expensive that either a hardwired EVSE or NEMA 14-50/6-50 EVSE.

it's your call - but either approach is functional

So basically the issue he's saying is because of the porsche charger not issues with being able to actually do it or costing a lot more. Also, I thought I read you shouldn't use the porsche charger?

So if im reading right (let me know if im misinterpreting) my options are...

1. 50 amp and use porsche charger

Or

2. 60amp but I'd need to also buy a new charger

pretty much yeah - but at the end of the day some (not all) owners end up buying a non-Porsche EVSE anyways due to issues with the Porsche EVSE…but other's don't.

50 amp and use the porsche charger _OR_ still buy an alternative 50 amp EVSE due to known issues (real or perceived) with the included Porsche EVSE.

or

60 amp hardwired (20% faster) but then you must purchase a non-Porsche EVSE since it's hardwired and not 60 amps

the core question is "will you personal experience with the Porsche EVSE" be problem free or one of the customers that has problems leading you to eventually replace it out of frustration - that requires "crystal" balling in the future - so there is no firm answer.

I will say if you go the 50 amp route, use the porsche charger, but eventually become dissatissifed with it and end up replacing it - at that point in the future (which we can't predict) it will be pretty obvious (in my opinion) it would've been easier to just buy the alternative charger in the first place and get the 60 amp one…

the Tesla J-1772 Wall Charger which is adjustable from 15-60 amps breaker size - hardwired, and can in the future be shared with a 2nd charger for dual charging duty is $550 + tax and shipping

Wall Box adjustable 15-60 amp EVSE is $649 w/overnight shipping from amazon.

but the Porsche charger is Included…so that's the cheapest approach if you remain satisfied with it long term - there is a significant portion of the Taycan community that has decided they were dissatisfied with the included Porsche EVSE and spent money on a replacement - there is a silent majority of Taycan owners that are using the Porsche EVSE and may not realize they are dissatisfied (which means they are actually happy because they don't know any better - silly silly people - why don't they live on the internet w/complaints and obsess over this stuff).

I'm all for "future proofing" - this is your first EV not your last - I'm a fan of a doing a bit more for the current EV and the future EV - and getting it done once - which means going a bit beyond the minimum requirements...

a Generic 60/80 amp EVSE hardwired will be an excellent EVSE for your current EV and your FUTURE EV's…but so would a NEMA 14-50 outlet and you can then easily ditch the Porsche EVSE for virtually any alternative NEMA 14-50 EVSE…

this is Porsche's official advice for new owners…

https://www.taycanforum.com/forum/t...-related-porsche-ntsb-article-analysis.13902/

following their advice does NOT lock you into their EVSE - but you may choose to replace it after living with for a while - or you may not - we simply don't know what your experience will be.

if you do end up replacing it - you'll be limited to another 50 amp unit - but it will be an easy/trivial swap - unplug the porsche unit, plug in the new unit - I'd be surprised if it even took 10 min.

but if you install a 50 amp circuit and in the future want to upgrade it to "more" that is an entire 2nd electrician visit, new breaker, new wire, etc…

so it's a matter of how much do you need today, what will you need in the future, and are you willing to pay more today to avoid future electrician visits? Again keeping in mind 50 amp's isn't that bad - but there is faster options if you choose to invest more now for the future.

I have a 100 amp dedicated circuit, a subpanel in the garage - 3 Tesla EVSE's - and routinely charge 2 EV's overnight and frequently 3 EV's when friends are visiting on weekends - the 3 EVSE's are hardwired - and I have a NEMA 14-50 socket - that I use for testing, and backup if/when the hardwired EVSE's are broken (or offline cause I'm playing with them) - a single 50 amp NEMA socket simply wouldn't do it for me - given the number of EV's in my circle of family, friends, neighbors and my personal insanity about having infrastructure to play and test all this stuff....but I'm completely nuts and not a model to aspire to.

Awesome info! I don't see myself needing anything other than for the taycan anytime soon. I thought there were issues like the charger would make the battery go bad faster or something. So, guess I just have to decide if I just want to go with the cheaper option and go 50amp or get a new charger snd go 60.

Thanks again

shouldn't use the Porsche charger is too strong a statement…

forum member experience with the PMC+/PMCC is that there can be issues with Porsche's offerings in this space - and to some owners those issues rule out the Porsche charger as an acceptable reliable and daily device, other customer's are less concerned or have experienced fewer problems.

what is 100% clear is that if you fall into the population of customer that find the Porsche EVSE issues "unacceptable" Porsche has no response for you, and no intention of addressing any of the issues which at this point in time are "known to exist"

so you're either happy with the Porsche EVSE (PMC+/PMCC) or you're not. If you're not happy with the PMC+/PMCC you can not expect Porsche to offer any restitution or even agree that your feedback indicates a problem.

Porsche has been pretty clear that they do not consider the PMC+/PMCC as requiring any changes to improve them. There are Taycan owners (myself included) that feel the product does require changes, but Porsche to date seems to feel "it is what it is" and no change is required…

I (and others) are no longer routinely using the Porsche EVSE's for any EV charging duty. I have no data as to how many actual Taycan owner's are in the same boat.

Re Porsche EVSEs: quite a few posts in here from owners who report problems with Porsche EVSEs only started after a year of use. Also, should you have questions or need help with your Porsche EVSE after purchase, no dedicated, knowledgeable customer support for them, unlike other brands.
Lots of good EVSEs available - avoid Porsche-branded ones.

Getting 60amp. So, if it was you you'd go with the tesla charger?

the 3 top choices in my opinion are:

• Tesla J-1772 Wall Charger $550 (adjustable 15-60 amps) - tesla.com website
  • optional $60 glass face plates in different colors
  • future 2nd Tesla Wall charger can "share load" for dual eV charging (J-1772 or NACS plug type)
• Wallbox Plusar + $699 (adjustable 15-60 amps) - amazon price check
  • I believe sharing is also possible but confirm if important to you
• Enphase/clippercreek HCS-60 $1099 (fixed capacity)
  • can do share2 functionality with 2nd HCS-60 for future
  • enphase website pricing

The Walbox 48 amp is $650 on bulbs.com, that's where I purchased mine.. It does support load sharing among multiple chargers. It also supports OCPP which may qualify for a reduced per KWH rate from your utility.
