How Many Amps Do You Need For Home EV Charging?

Nice work Tom, very informative and explained perfectly. Those of us who live in the EV world sometimes forget how many questions people new to EV's have.

One other thing people should consider is if they have “Time of day electric service” it may actually save money in the long run to install at least the fastest EVSE/circuit their EV can support, so that it can reach their preferred state of charge in the cheapest rate window.

Just for info, here in the UK (240v power supply), the standard for single phase home chargers is 7.5kW - 32amps. The grid connection

my electrician told me my panel has 90 amps and around half of it is being used currently. That i would need to upgrade my panel to 200 amps to be able to use EV charger . Thanks to your video, I can go back and ask him the right questions.

Finally someone that knows how to explain. Its called a PROFESSIONAL! Subscribed!

Electrician my self, can’t explain better than you have. Got many answers. 🙏

Best one stop shop for learning everything EVs. Thanks Tom! there no as comprehensive video as yours available on the net. Thank you for your service!

Tom, god knows how many youtube clips I have seen so far on this subject, and yet your clip was by far the best ever created, explained, and right to the points. I enjoyed it much. Thanks for your contribution.👍

Thanks for making this video. I say that not necessarily for me. I just purchased my first EV in March 2023. Prior to making the switch to an EV I had to do a lot of research on all the topics you covered in this video, especially the topic of things to consider when your home has limited amperage. I think if your video had existed it would have cut down on the amount of research I would have had to do because it's all explained very succinctly and concisely in this one video. So, hopefully, future potential EV owners will greatly benefit from your video.

Excellent timing of this video for me. I am in the process of choosing an EV to replace my X3 in few months and want to have a L2 installed. This is an important topic for people to get educated on. 👍👍

You do such an outstanding job in all of your videos. I always recommend your channel to anyone who has EV questions. Top notch. Thanks for what you do!

Very well done. Every potential EV owner needs to watch this!

Thank you. Bought a new plug-in hybrid and the manufacturer provided little info. This is just what I needed. Appreciate you.

Very well done. Every potential EV owner needs to watch this!. Very well done. Every potential EV owner needs to watch this!.

Awesome info Tom, I’m an electrical engineer and I agree that it’s best to over build when it comes to the circuit and EVSE. I’m new at the EV game and still learning stuff every day. One suggestion I would make is to include one other electrical property called, “resistance”. Unwanted resistance can equate to inefficiency. Example: My idea was to use a 50 amp circuit (I’m limited because I live in a condominium) which dictates 6 gauge electrical wire and a EVSE designed for 40 amps. The EVSE I bought was a Wallbox 40 amp unit which is a very popular brand. But what I learned is the Wallbox 40 amp unit only uses 10 gauge wires for the 25 foot EV service cable. I noticed when I charged my vehicle, the cable would get very warm to touch. The smaller the wire, the more “resistance” creates heat loss which in turn loses money in the long term. I’ve decided to change to an EVSE designed for 48 amps and dial it back to 40. My hope is the new unit will have a larger gauge service cable and run very cool. For those who may be confused about my numbers, the lower the number, the larger the wire. Hence 10 gauge (10AWG) is smaller than 6 gauge (6AWG). Most manufacturers don’t mention the gauge wire used in the service cables. It would be great if you added those figures when you review the different EVSE units. Thank you and keep up the great work!

Great video, Tom. The chart says it all. There isn't very much information on this basic charging technology out there, and it will be an eye-opener for most people (who are not technically schooled), even for people who already own EVs—who will no doubt be advising friends and relatives. This is especially true when most charging stories in the mass media exclusively talk about public charging—the familiar gas-station model. My charging station is on a 30-amp breaker, but using a 40-amp cable to the EVSE; the heavier gauge cable costs only a little more.

I sincerely want to thank you for the quality of this presentation! I now understand the terminology and functionality of charging operations. Will receive my ioniq5 in a week and will listen to your other presentation in your list about my incoming I5. Thank you

This is the explanation I've been searching for. Well done. Thank you.

This great video should be included with every EV sale (or demo)! 👏👏👏!

I've been looking for a video like this for awhile. Good job!
