Tesla Gen 3 HPWC POWER SHARING in action! Model Y vs. Ioniq - How Does it Work?

- Testing Tesla's power sharing feature on my 2019 Ioniq EV and 2022 Model Y Performance. This feature is now wireless between the new Gen3 Wall Connectors, and is great for sharing a limited amount of power for charging multiple EVs. I can't wait to get a third wall connector now!
Not an expert. Just an opinion. If you have two separate circuits then I wouldn't think power sharing is necessary, unless you are trying to reduce the load on your whole panel.
If they were sharing a circuit, then it makes total sense to avoid overloading a single circuit.
Correct and good point! My two Wall Connectors are on a subpanel that also feeds other areas of the house. If both WCs were charging @ 48A, there are 2 mini-split units and some heaters that would not be able to run. Today I have the load share network set to 72 amps, that gives me plenty of headroom on my 90A subpanel now for everything else that's on it.
It's great to see a video proving that the Gen3 wall connector can power share with the j1772 wall connector! THANKS!
My pleasure! I just preordered the new universal wall connector as well. When it arrives I plan on power sharing all three, hopefully there are no issues. :-)
@fiehlsport Please do! I was planning on buying the j1772 wall connector in the next couple of months and power share it with my NACS Gen3 wall connector like your video, but now I plan on getting the Universal Wall Connector if I can power share with the Gen3 charger. I'm really looking forward to your video on this! 😊
Great video! I just had both of those same wall connectors installed for a Mercedes EQB 300 and a Cybertruck (hopefully soon!). They each have their own 60 amp breaker.
Awesome! Great charging setup for a nice pair of cars, if the CT ever arrives. 😎
I just installed two universals and the load sharing works incredibly well. Hopefully with a software upgrade it will be able to read non Tesla ranges and prioritize based on that.
I was hoping you can help me with my question. Because I was unable to find this information on the internet. I purchased two chargers one is a Telsa universal gen 3 charger, and the other is a Telsa standard gen 3 charger. When installing these units do you need to use the small wiring 18 gauge that connects to the charger on one end and the other to a power management device that would be installed in my electrical panel in order for power sharing to work or did Tesla do away with the power management device, and everything is just monitored between the two chargers via your Wi-Fi network. Also, I plan on installing the two chargers on their own separate 60-amp breakers to my sub panel which is only rated for 100 amps.
@@milkdud7457I’m presuming you’re talking about the Tesla Dynamic Power Meter? From what I’ve read this will adjust Tesla wall connectors (Gen 3) based off the house load. If you have multiple EVs and only 100A service, this might solve your issue. Looking at a solution for 5 EVs on a 200A service, thinking Tesla Dynamic Power Meter might manage this for me.
@@NO_OPEC_NO_PROBLEM You cannot use the load management device with power sharing, unfortunately. Just an FYI. It's only for single wall connector installations.
Load sharing is for connectors on the same circuit. Why use it if you ran independent 60amp circuits ? It also takes a while to load share. Like 20+ min
The Gen3 manual states that each wall connector must be on its own circuit for load sharing. Previous generations were permissible to wired as you described though.
Load sharing is pretty much instant, it adjusts the current between the two cars in real time in my experience
How Tesla Wall Connector index different car energy consumptions? I want to share with my neighbour, and share the bill. Will his/her nontesla car will be indexed as intorduced with VIN once? Will Wall connector idintify it?
Energy logging is not great, at present. You would probably have to get some sort of third party energy monitor (Emporia Vue?) to clamp onto the feeders in the electrical panel to measure how much power your neighbor's wall connector consumes. Tesla does log each charging session in the Tesla app when the wall connectors are added, but you can't export the totals very well. It's clunky right now.
If they have thier own 60 amp lines, how are they "sharing"?
They are sharing the subpanel’s main feed, which would be overloaded if both wall connectors worked at 100%. Using power sharing gives me headroom for the other devices in my house that use the subpanel. Without it, I wouldn’t be able to use my clothes dryer, or other heatpumps in my house while charging.
Do you know if the power sharing feature works for 2 chargers on the same circuit?
Yes, it can, though the Gen3 manual advises that the units be on their own dedicated breakers. The Gen2 HPWCs could be wired in a method that shares a single breaker, and implements power sharing to make sure they don't exceed that rating.
Yes, absolutely. In fact, I can't think of why somebody would do power sharing on two circuits. Makes no sense. From the Tesla Gen 3 support web page: "By intelligently managing available power on a given circuit, power sharing allows a single electrical circuit to support multiple Gen 3 Wall Connectors while still ensuring your electric vehicles get a sufficient charge." Notice it says "on a given circuit". Thats ONE circuit.
@@TheTinRam each wall connector should be on its own branch circuit, or circuit breaker, per the Gen3 installation manual. The older units permitted tying multiple units into a single circuit using a junction box - that is no longer shown or mentioned in the installation book.
Each unit should be on its own 60A breaker with a dedicated feed to and from the panel. I believe “on a given circuit” was poorly worded and they really meant a home’s electrical service, not circuit.
@@fiehlsport "power sharing" connotes sharing the same circuit. if they're each on their own circuit with separate breakers, then what are they "sharing"? to me, they're just "sharing" the house load which is the same as both units running on their own separately without this "power sharing" feature.
@@sarg1843 It is still useful if they're on their own circuit in a main panel. If you have a 100A service, you don't want to run two 48A wall connectors simultaneously, but running one might be fine. Power sharing will let you limit it to 50, 55, 60 amps, whatever you deem safe for your installation and usage habits when two vehicles are charging.
