CyberTruck home charger

[kdn]

I would like to know what charger we will use for the CT when charging at home. I would like to have my charge installled and ready to go. Tesla charger on Amazon for $375 seems like a deal. Should I purchase one or wait to see what they announce the CT requires for home charging?

There will be a significant delay between the announcement and your delivery. I think you'll have time.

I can get a rebate for installing home EVSE, but only after I have a VIN. So I'll be cutting it close lol

I will continue to use my OpenEVSE. So "we" can use that

If you are worried about timing the purchase/install of the charger, my suggestion is to take the recommended wiring/circuit breaker configuration for the current high powered wall charger/connector (HPWC) and have an electrician establish the connection as soon as possible. Once the charger arrives, it will simply be a matter of having the electrician install it on the newly installed wiring. I would also recommend having a friend come over with their Tesla and test it out to ensure it is fully operational before you take delivery. I have a version 1 HPWC that supports 80A charging (my 15S85D has the dual chargers) installed on a 100A breaker. Luckily, I live in a house that had enough "spare" room in the breaker box to accommodate the charger's breaker. FWIW, charging the CT at home should be no different than any other current Tesla out there, it will take a charge from either the mobile charger or a more permanently installed HPWC (the current one supports 48A of charging) https://shop.tesla.com/product/wall-connector.

I’d like to see a new charger that goes directly from a Powerwall to the CT. Straight DC-DC charging. I could even feed it from the Solar through the PW to the CT. I know they now have the “solar charge” option, but it isn’t the time of day I’m looking at, it’s the source.

There's a couple of companies that make solar direct EV chargers. There's no reason to go via the Powerwalls, unless you want to discharge them into your CT as well, which in turn adds cycles to the powerwall for nothing if your CT is at home anyway when the sun shines.

If your EV is home while the sun shines, then charging from the powerwall wouldn’t add any cycles, provided you set the charge rate to equal the output of the Solar system. You are just routing the power to the EV instead of back to the grid. This would just give you options of using the PW charge to fill your EV. And if the CT has a DC output (I know, AC works as well), then you could recharge your PW from the CT in the event of a cloudy dark winter day and the local grid is down. Take the CT to somewhere there is power, recharge, and refresh the PW at home?

I specified that it would cycle "if" you discharge the PW. Not if you used the solar directly. But this is also difficult to achieve, in that it's hard to follow the solar output directly through the PW, as there's no way to control it in realtime.

There's a few options but it depends on what you want to achieve. The primary reason to charge with DC is to avoid the DC-AC-DC losses. But you need to charge at the DC voltage for the CT, so ideally you'd do that straight from the PV line through a MPPT controller DC charger that can output up to 500V DC depending on your string voltage and controller. It then needs to negotiate with the vehicle to configure the plug for DC charging, at which point the vehicle then tells the offboard charger what power configuration to send down the cable to charge the batteries in the vehicle. The DC charger part is not onboard the vehicle, so you need one on the outside.

In the case of the PW they only have a 50V battery supply internally, that is boosted up to 240V/110V through the AC inverter output. This is a similar config to most other battery inverters out there. But 50V won't get you far to DC charge a vehicle with batteries over 400V.

There's nothing really stopping you from using the CT, and it's internal inverter, as a PW. So you can go down to a SC and recharge and bring that power back home to use via the CT inverter output. This is already common on many other Ev's with V2X/V3H. Ultimately the PW is a poor value proposition overall and doesn't allow much flexibility to DC charge, or direct solar charge. There are better options.

Thanks! Great explanation. I do appreciate it.

Are any actually commercially released yet? I know plenty that have been announced, some in testing, but none actually available for order yet AFAIK?

powerwall to vehicle is not going to work

there are other brands with solutions to that problem coming soon though.

you can use DC off the roof directly with Storz power which is the only string inverter worth having. Solaredge can also do this.
I’m aware or 3 other brands that will offer this soon, a couple of which I have beta versions of.
