A quick update regarding some not-so-quick shipping
Added 2024-12-21 00:48:28 +0000 UTCYeah, once again I'm stuck waiting on a thing.
Contains spoilers for the (hopefully) next video and also - sorry for the less-than-great audio!

Ah, I hadn't considered it from a North American view, if most EVSEs are 2 phase 220v, but domestic appliances are 110v. However 220 to 110 stepdown transformers are readily available in Europe as many worksites require 110v tools to meet safety regulations. I found a 3kW version for €/$1003kW from a reputable trade supplier. I'm sure something similar could be fitted in an RV. In Europe we use 230v per phase, and all domestic sockets get 1 phase and neutral. Domestic EVSEs here are also single phase 230v, but many public / commercial ones are 3 phase (often called 415v, but still 230v per phase, each phase being 120° apart) The Type 2 Mennekes IEC 62196 connectors have pins for 3 phases and neutral as well as Earth, PP and CP. So no issues here connecting 1 phase + Neutral from an EVSE to the AC wiring of an RV/campervan/motorhome.

2024-12-23 09:38:41 +0000 UTCSort of. A big complication with RVs<-->EVSEs is that the EVSE supplies a 240v phase-to-phase connection -- no neutral, thus no 120v supply, unlike an RV plug (4-prong: line, line, neutral, ground) that gives two 120v circuits (line->neutral, and neutral->line, to each line). The lack of split-phase completely barfs all the circuit design of the RV, and (almost) nothing would work without a neutral. But to charge the leisure battery quickly? Sure, that could be a thing - might be beefy and expensive (doing high-current *anything* makes the components pretty big, and the low-voltage/high-current nature of RV batteries usually makes that a challenge). I'm sure there are companies thinking about it, though...

2024-12-23 08:46:25 +0000 UTCI had a similar problem this week. I was in a renter campervan that uses 12v leisure batteries to power a 2kW inverter (240v - it's Europe). Those batteries can be recharged slowly from the vans 12v battery while driving, or solar panels (but only a few hours of daylight at this time of year) or a campsite mains supply (but no campsites open in December) When the leisure batteries are depleted after a few days off grid my coffee machine won't run. Sad Face. I drove to a nearby EV charging station. There were DC CCS chargers that can give the van 100kW at 400v DC or AC points that can give between 7 and 50kW of AC to the van's onboard charger for the HV/traction battery, but none of that is available to the AC sockets inside the van for my coffee machine! All I can do is wait while the leisure batteries get a few amps from the van's DC-DC converter. Even for ICE based campers, there are benefits to being able to plug into an EVSE point, because they are everywhere now. I don't expect manufacturers of the base EC vans to support camper conversions to tap into the AC going to the onboard charger, because they'd have to allow for load balancing - charging more slowly because somebody's turned the kettle on and you've only got a 32A cable. However, a camper conversion company could use a dedicated AC charging port to supply the onboard AC systems and recharge the leisure batteries at the same time.

2024-12-22 21:48:23 +0000 UTCI've got 2 of those form factor heaters. When I went to buy the second one i had a hard time finding one with useful modes of heat level. The first did 3000W, 4500W, 6000W. Eventually found what I wanted. The lower 3000W is useful once the garage is warmed up.

2024-12-22 15:02:39 +0000 UTCSince that heater has a contactor in it already, it wouldn't take much smarts to only close the contactor once connected to the EVSE, and if it can supply enough current, and to open it if you hit the disconnect button.

2024-12-21 20:04:51 +0000 UTCThank you for the casual video! That sounds like the kind of hacky thing that I might try with the technology in my house. You know, you could do something like a Desultory December video, sort of a stream of consciousness, not knowing where it’s going to go video about a piece of tech you have laying around.
Kevin Mitchell
2024-12-21 19:04:53 +0000 UTCWhat a nifty idea, I do hope it becomes more of a thing for circumstances like people who’s laundry is near/in their garage and need to share a circuit for a dryer and EV charger. Also the way the charger plug dangles perfectly in line with the wall plug for a little bit at the start I thought you had somehow spliced the two power cords together into one plug and was very confused because you definitely know better than that

2024-12-21 15:05:12 +0000 UTCBTW there are also hard-wired analogs such as simpleSwitch that are less expensive than full smart panels, but they don't serve this particular purpose as well.

2024-12-21 12:39:28 +0000 UTCI’m guessing the “ less-than-great audio” wasn’t intended to refer to the AI generated Deutsch audio track, but thanks to the wonders of YouTube AI audio and Apple AirPlay that’s what plays automatically via AirPlay (as the AI German audio is the first audio track, and AirPlay only plays the first audio track). The future is more broken than I was promised :-/ (Not really sure why AI audio translation got enabled for this video though.) Ewen

2024-12-21 08:26:45 +0000 UTCElectric stuff is neat. And could be even neater. But now I will go and fill my car with dead dinos. I like the brumbrum.

2024-12-21 07:50:35 +0000 UTC-1. It's just PWM saying "amps?" and a voltage level saying "go, no go?". It's entirely analog for J1772. DC charging with CCS actually does the same (except the amperage level it expresses is defined to mean "no, digital please"), but also adds an RF-level, WiFi-like network signal over the pilot signal, through which digital data (literally Ethernet and IPv6) is shared. But yeah, for AC, it's absurdly simple and basically just a glorified extension cord.

2024-12-21 06:30:38 +0000 UTCodd that Patreon seems to have no way to send or post an image, and Mastodon doesn't seem to have DMs. this goofy post-facebook and post-twitter world is all garbled up. LMK if you want a peek.
Matt Falcon
2024-12-21 06:23:16 +0000 UTCI've got one from J1772 to NEMA 14-50. I use it to test repaired stations (long story short: free charging at work, not free at home, why test at home?). If ya get it back to me some day, want me to express ship it to ya?

2024-12-21 04:19:52 +0000 UTCIf you're going to make a video on shared 220V I think you should look at including circuit splitters like https://splitvolt.com/
Jerrad Pierce
2024-12-21 04:18:14 +0000 UTCFor DC fast charging, yes. AC chargers just broadcast a PWM signal for max allowable current the car can take.

2024-12-21 03:33:35 +0000 UTCNo, this is just a way to provide power to that heater without needing to run a new circuit for it

2024-12-21 03:29:03 +0000 UTCIs there not a way to have a dual nema 14 receptacle with an interlock to only allow one to be hot at a time?
Alex
2024-12-21 03:25:50 +0000 UTCThat plug has more than just current in it, it also has a data connection for negotiating voltage etc.
Tom G
2024-12-21 02:09:15 +0000 UTCOr just turn the car on and set its heater to max 😅
Tom G
2024-12-21 02:06:56 +0000 UTCI have one of those heaters! First 220 circuit I ever ran from the breaker box! As I recall, the mfg wanted it hard wired, but I installed a plug, as you did.
Darren Pierce
2024-12-21 01:38:23 +0000 UTCSo iam not as tech savy or brainy as you, but will you be able to run that heater off your car incase of a power outage?, 🤔
