There are also these:
Long-time EVer Stefano Paris recommends using Milbank panels that combine outlets with dedicated circuit breakers so you can easily cut the power before plugging and unplugging. You can also add in a submeter to track usage.
And in main land Europe, you can buy a preconfigured unit for outside wall mounting ("Drehstromkiste")
Though circuit breakers are not cycle rated for twice daily use.
It's not hard to replace a worn out breaker, well worth not get zapped when plugging or unplugging.
Well the outlet is now in at our 2nd office, sans switch. I'll start using it Tuesday. No handle on my UMC so just have to be careful.
Looks like this is the one for the UMC: PLUG DOGS 50 Amp 4 prong - Coil nWrap a Cool RV Products Store
I'm thinking this would be a worthy purchase considering how often I'm going to be unplugging this. Thanks!
Got mine at the local RV accessory showroom. Replacing the end with a yellow handled plug is the other way to go.
Looks as if it would be easy enough to make if you had some strap material, maybe an old cargo strap. Just make sure it's not conductive, or wet :scared:
Well yeah, that's a valid point :redface: I guess that's taking DIY beyond rational thought :biggrin:
How do those straps fair if you get a hot pin I wonder?
True, but that is 'under load' (unless Switch Duty Rated). If you slide the switch on the UMC to off then current is stopped and the breaker is spared abuse when you switch it off to eliminate the shock hazard at the plug. Unplugging under load will burn up the plug before it trashes the breaker.
Point taken but there is still the mechanical part of a breaker. Another bit not designed for twice daily use. More like once a year or so.
It may depend on the breaker. The charger in my conversion, a Manzanita PFC30, uses the circuit breaker as the on off switch. They've been in use for years and I've never heard of a recurring problem with their use.
> A 100% charge in standard mode is to 85% SOC but it is still supposedly good to finish soon before you leave in the morning although it does balance the cells for maybe an hour after a standard mode charge. [dsm363] - from: firmware wishlist thread. Might make more sense here:
The basic 120 volt 'emergency' charging cable does this balancing process silently, obviously, so unless you are watching the Roadster screen real time, you would be unaware of this process. As I was. Lately using the 'big charger' I heard all this clunking going on outside the house and investigated. The screen just said: charging, charging stopped, charging, charging stopped, etc etc. alternating every 30 seconds or so. So I stopped charging & disconnected thinking it was the fault of the EVSE. Have done so a few times. This is why I've been only getting ~185 mile charges lately instead of ~194, DOH!!
There are other methods to balancing, but this is the everyday method, apparently.
When I find this going on in future I'll just switch to the basic cable and let it finish balancing in silence. And when I go away on a trip I'll now use the basic cable instead of the big EVSE. No moving parts and it has never tripped the GFI, whereas the big EVSE a few times has gone PROTECTION mode, with no car connected, so not something I want to trust for weeks at a time.
I've never seen it do that, and I've seen it finish charging on my HPC more than a few times. So I'm not sure that is normal.
That sounds bad. Did you get a red ring on the charging port?
I would suggest getting the logs checked by Tesla.
Roadsters should have an HPC at Supercharger sites!
I'm still trying to process the news that the supercharging sites will NOT have a Roadster HPC. I'm not feeling the love.
