A really good explanation for those that want to join the EV revolution. I owned a 2011 Leaf until the battery was more than halfway gone. Now I have 2 PHEV’s. Thanks for your efforts to educate, Travis.
The graphics were top notch and the narrative was the best I've seen on EVSE----great job Travis! It flowed from start to finish without technical mumbo jumbo that isn't necessary. You didn't go off on the "inside the garage" tangent that a lot of videos are doing since California insurance policies are now asking for limits all sorts of conditions on usage, AMPERAGE RATINGS, if people are at home etc. And of course in Ca any day now they Bi-Directional charging may make level 2 EVSE's static items
Some EVSEs require a good WiFi connection (eg Chargepoint Home Flex) in order to function properly, so one should ensure such is available.
I have a 32 amp evse for my PHEV.
I had the electrician install a separate breaker box in the garage with a plug for the evse and had him run a 50 amp line from the new box to the original. Just in case I ever upgrade to a 40 amp evse.
Right now the car's onboard charger is rated at 7.7 kilowatts, so the 32 amp evse is fine and means that I have extra cushion for continuous load.
If the next car has a 9.6 kw onboard charger instead of a 7.7, then I'll upgrade to a 40 amp evse unit.
Thanks for the video. What was your reasoning for installing charger on outside of garage? Any pros or cons either way?
Great question! In my specific case I have a fairly small garage and I also often have multiple BEV/PHEVs at once so I wanted to be able to swap between vehicles without having to change where they're parked. If I wanted to move the unit inside I could do so pretty inexpensively. -Travis
Do you need to pre condition for home charging?
No need, the rate of charging at home is a fraction of what DC charging provides! -Travis
Travis, At the same moment you posted this educational BEV charging video, Alex and Nick posted a video about a fire breathing, CO2 belching V8 station wagon.
Which video should I watch first? 🤔
I won't blame you for watching the more fun one first. -Travis
@@EVBuyersGuide That's very big of you.
If you are going to plug into an existing 240V socket, like for an electric dryer, CHANGE that socket to a commercial grade socket. Even if the existing socket says it says it it rated for like 50A, the cheaper big box and builder grade sockets are designed for intermittent (hour or two) use, NOT the several hours at a time continuous load that an EV charger will do.
Cheap sockets can get hot, melt their cheap plastic, cause a fire and burn your house down. Since most people charge overnight that is exactly the time you do not want a fire in your garage, that probably does not have a smoke alarm. (You want a temperature rise alarm instead of a smoke alarm anyway).
I understand why you placed the charger outside but do you worry at all that people will come by and use it when you’re not home?
I had this conversation with a coworker who lives in a condo complex wanting to put in chargers. No one is going to a random property in the middle of a development or residential neighborhood to use a charger for 6 hours. And if you're really paranoid about a charger and someone using it, you can get one that's smart and can be programmed to work with only cars you approve.
I went with the 40 amp plugin option thinking that if my EVSE died I or my wife could easily swap to the 32 amp portable unit. After watching Sandy Monroe’s video about electric fires with substandard outlets, I wished I went with hard wire.
Highly recommend hardwiring the level 2 charger. There are too many potential issues 240v plugs not really being rated for continuous use.
Hubble nema 14-50 Tesla recommended too
I received similar quotes for an even more straightforward installation. Why in the world are we paying $1,000 for electricians to install $100 of wiring in an hour?
Just speaking for myself, it's not worth saving $900 at the risk of losing a house. I don't know enough about the process to be comfortable trying it myself. -Travis
If you get ANY part of it wrong, you lose your house. Insurance won’t cover self-installation if something happens, but you do you, boo.
@@jeffforbess6802 I'm not advocating for DIY. I'm just baffled by people being okay with paying $900/hr
Can you choose which vehicles can charge on your charger through the app? Can you choose which non teslas can charge? You have your charger outside so could someone theoretically park their car in your driveway if you're not home and steal your electricity?
I think the person that quoted you $3500 had no intention of doing the job. they just wanted the fee to come out there.
I think the $3,500 quote is hoping to catch people who don't know any better but either way it's a shady business practice.
I'm able to adjust access to my EVSE via the app. The quick options seem to be "Any Electric Vehicle", "Any Tesla Vehicle", and "Only Authorized Tesla Vehicles". I'm also able to allow access to my "Tesla Energy System" for 5 users but I don't believe this would extend beyond Tesla vehicles. I could also limit the EVSE function by setting up timers so it only operates at certain times. -Travis
I have a Clipper Creek 40amp EVSE with a J1772 connector. If I were to buy a 2025 Hyundai IONIQ 5, it will come with a NACS port. How will I be able to charge it at home? Maybe the IONIQ 5 will come supplied with an adapter.
You would need an adapter and I wouldn't be surprised if Hyundai includes one. Worst case scenario they would have one available for purchase. -Travis
Other option is to buy a cable kit from manufacturer and change it out. I too wish the US would had retained the original CCS standard and required the only other auto vendor of the NACS change to it. As the rest of the world is keeping the superior CCS standard because of it's higher capabilities...especially now for the coming 800V architecture of newer faster charging platforms like the Hyundai group vehicles. You will find that charging on the small Telsa DC chargers they can only charge at about 100Kwv versus the true Super Chargers of the other CPOs where 800V architecture will more than double that rate. Thus allowing true fast charging of 10-80% in 15-20mins, thereby showing the superior hardware and connector.
That's assuming the company sells a replacement cable kit. They may or may not. -Travis
Plan to replace it all every five years or so. I’d fx that into the overall cost of ownership, as EVs are now taxed at a higher rate, with electric rates going up, higher insurance rates coming and wear and tear due to added weight. Oh, and depreciation is sky-high. It’s fine for a lease, I guess.
Also, good call charging outside, to prevent a runaway fire poisoning your family and burning down the house. It’s rare, but it happens. As EVs get older, it will happen more imho.
Sorry to tell you...but your too fixated on the small Telsas. Currently, the GM/Chevy Ultium platform has an on board charger rated at 19.2kw using 80A or on a 100A CB. My Kia Ev9 draws 11.3Kw. Thus so as to future proof my installation, I chose a Grizzle Ultimate 80A unit, which is a smart EVSE and talks with the vehicle to set the output level per vehicle connected . You really need to research and educate yourself before putting this info out. I'm an electrical engineer working for US DOE.
I said most EVSEs are up to 48 amps, not all of them. Yes, there are higher output EVSEs and vehicles that can go above 11.5kw but right now it's not many, not many at all. -Travis
An 80 amp unit would require a 100 amp breaker from the little research ive done . If so not many homes have enough space in panel box since most homes have a 200 amp panel?
Not sure I would want that much current running through my attic to garage.
That's why we have Government waste-planned obsolescence! Why would someone purchase an EVSE today without knowing what the hell is forthcoming with future EV charging? Travis scored a 100% homerun here. As EE's we should nudge him with tidbits of info for an upcoming video on Utility demand factor and a work etc as reactive power is a sneaky cost that few people are talking about! The man just produced the best video I have ever seen on EVSE!
@doziershaw9765 Yes... That's why I installed service entrance 2 gauge conductors to ensure plenty of load capacity. I have three panels in my home for 500A service and a dedicated 50KVA transformer for my rural acreage, so plenty of capacity.
Travis did an outstanding job with the video and explained the difference between an EVSE, Electric Vehicle Supply Equipment, and the AC onboard AC charger. A friend wanted to charge a new Bolt EV. He started bragging 0:01 about his new 19.2 kw "Charger" 100 amp breaker with 80 amp usable. I asked him if he had used it and if it was faster than his old 32 amp EVSE. He said, "Sure, it's 80 amps." I explained to him his Bolt would not charge any faster to to the onboard AC charger, and he was pissed. I am so glad you called EVSE'S the correct name. 😊
