Home charging

It depends on your length. I priced it out and for 1” EMT, 4x 6 awg conductors (240V plug needs 2 hot, neutral, and ground), 240V 50A GFCI, gangbox, and trim plate was $750 in mats. $2400 seems semi-reasonable. It just depends on where your panel is.

Lol, the panel is literally already in the garage!

I would literally want it right next to the panel. Maybe even one outside on the other side of the wall.

This here is the ideal situation.

Perhaps Treehouse thinks money grows on trees!

Oh yeah that’s ridiculous then.

Based on all of this and some guesses about efficiency while towing my boat...

I normally go sailing on Sunday, so Friday after work, if my SoC is under 35% I'll plug in and the truck will be at 100% when I hitch up the boat on Sunday morning.

I should be able to go sailing 3-4 times between each charge. I sail an average of once per month so I'm looking at charging the truck once every 3 months on average.

I'm assuming

• 1.95mi/kWh while towing (estimate from ABRP).
• 30mi (15kWh) round trip
• 1.15kWh from my level 1 outlet (15amp with the charge loss mentioned above)
• Keep battery at 10% or higher.

I was thinking about getting the level 2 setup if for no other reason than to improve home value, but I certainly don't seem to need it.

I'm hoping one of the few internal features the Slate will have, is the ability to limit charging current/wattage. I have an external 120V outlet at the back of my garage that I could use for charging, and it's a 20A, but I'd still like to lower the maximum charging current draw to 8A or less so I can still use other stuff in the garage*. Slate won't be my daily so I don't mind waiting for the charge.

The fuse panel's in the garage, so if the Slate works out I'll probably pay to have a proper 220V line ran from it to the outside of the garage where an exterior charger will be installed. Much like Saint Alban's.

*Also I did all the electrical in the garage myself so I don't want to tax it too much LOL

You're in luck then. I think most level 1 110v chargers put out about 8a when plugged in to a NEMA 5-15 outlet.

If you watch this quick video, this guy goes through the menu accessible from the cruise control buttons when the vehicle is stopped. There is a setting for "charge current" and "charge limit". It is facebook, but no sign in required, just "X" out if it asks.

Beautiful, just what I wanted to see. Interesting it has the 100 or 80% as an option for stopping charging too. Wonder if those percentage options will change with the new battery chemistry.

fhats fun, too bad he didn't drill down into the "Current" submenu. Seeing how elementary the "Limit" settings are (100 or 80), I would not expect too much current control.

For Luxrage - I expect the Slates included EVSE to be absolutely the most basic of products with little to no control., especially in 120v mode. There are a wide range of aftermarket EVSE that do offer 120v current control, typically the "2nd tier"- the ones that have a "screen" (really just a LCD/LEC display with a button or two). For example, EVDance brand L1/L2 - it can be set for 6/8/10/12 amps at either 120v or 240v and 16a at 240v only. Its a breathtaking $120 on Amazon. (btw, with "screen" for physical control or with "app" for wifi/app control of current).

editorial: I know many folks will express safety fears with "no name" Chinese branded EVSE's, but I personally have no discomfort at these low current charge rates. I might spring for a more branded experience at 32a and above, as thermals start to be more significant.

It doesn't take much current draw for a poor design to pose a fire hazard, and anything that plugs into an electrical outlet can potentially become a fire hazard. There's really no need to cheap out on something like this and risk your life & property. Even 1200 watt toasters & hair dryers are tested and UL listed for safety.

I'm no subject matter expert here. But if you are curious and read about the various ways fires break out and how things go wrong, it would give you pause on questionable decisions. Things can go haywire quick.

I'm well aware, I've worked in commerical electric.
But I'm also aware that everything electronic is manufactured in China, and even most well-known brands are typically "co-designed". I promise you that Slates included EVSE will be the utter cheapest thing out there. Each to their own.

My plan is to install a wired Emporia Level 2, With 40amp breaker. My goal is daytime charging Using surplus PV generated power, preferring not to tax my off grid batteries and never charge at night.
