  1. Do Tesla cars come with a brake controller for trailers?

    The thing with the CT is that they'll have the inertial sensor, torque values for the two rear wheels, wheel angular velocity and vehicle angular momentum data available to them. I really hope they put a load cell in the trailer hitch. Combining it's info with that from the other sensors they...
  2. Do Tesla cars come with a brake controller for trailers?

    The cars? No (but they do have the harness). The truck? We don't know but think something built in probable.
  3. Colorado Teardrops Boulder EV camping trailer with 75kW battery pack

    Uh oh! My sister had (note use of past tense) a friend who went to get a refill for his barbecue propane tank and threw the new one into the cab of his truck. Have you ever noticed that the propane tanks on travel trailers are mounted outside? Have you ever noticed the signs that prohibit...
  4. Towing and charging

    This is yet another level of sophistication where UPSs are involved for critical loads which cannot be interrupted for even the briefest period of time. When the utility goes down a relay connected to it deenergizes closing a pair of NC dry contacts. These are wired to the generator which using...
  5. Towing and charging

    The tendency today is to approach the problem from the opposite direction. Instead of picking a handful of circuits which you consider essential you pick the biggest loads, prioritize them and connect them to your panel(s) through contactors. Everything else is connected directly to the...
  6. Towing and charging

    I thought we were talking about whether the CT would handle a whole house in an emergency. I am saying that based on the fact that I weathered many a power outage on a 7 kW generator for years and that I expect, therefore, that I would be able to do it with the 7 kW inverter in the CT (as long...
  7. Towing and charging

    I don't know where you are getting these ideas but as I mentioned in my last post I averaged 3.64 kW over the last 6 months which is 87.6 kWh/da, almost triple what the average US house takes. Median draw was 2.8 kW. I exceeded 7 kW 10.6% of the time. My baseline load was 1.65 kW. Given that...
  8. Towing and charging

    The CT inverter will be 30A at 240V. That's 7.2 kW. I have a largish house and pulled, on average over the last month, 3.7 kW. The average American house uses 30 kWh per day. That's an average of 1.25 kW. And the truck will have a 200 kWh battery so it would last the average guy 6 days (and me...
  9. Towing and charging

    For the outlets to be useful they clearly have to be capable of being enabled when the truck is in park and the driver is away just as dog mode needs to be. Just as dog mode needs to work when the car is plugged in so must the outlets continue to be active when the truck is plugged in. OTOH you...
  10. Towing and charging

    What I am hoping for is that that port (or ports - I'd like to see several) are for PV panels i.e. mate with typical PV connectors and have MPPT controllers behind them.
  11. Towing and charging

    This brings to mind a very (IMO) interesting question. If you can do this with a trailer you can do it with your house (with proper transfer switch). You could, for example, hook up some solar panels to an inverter and use the inverter to charge the truck but run the house from the truck...
  12. Towing and charging

    I can't see any reason why you shouldn't be able to do this. In fact I do it now with a Yeti battery pack that is "running" the garage I am having built while I wait (and wait and wait ....) for Powerwalls to be delivered. It's charger, which charges it at 180W, is always plugged into an...
  13. RV Brake Controller?

    Certainly there is an opportunity for Tesla to do great things in support of trailering given the powerful onboard computing with access to accelerometers, pedal position, regen system, individual wheel speed/slip data, torque vectoring and, if they put some load cells in the hitch, data on...
  14. Travel Trailer will charge my Cybertruck

    Check the Plugshare photos of the Strassburg, VA Supercharger station. These are not "pull through" but you can obviously "pull in" and charge leaving your trailer out to block traffic. Several stations (Vienna, VA; Joyce Kilmer) have on or two terminals set up for pull in at one or the other or...
  15. These Off-Grid, Luxury Travel Trailers Pack Enough Oomph to Power a Tesla Cybertruck

    No. Still waiting for parts but we don't need a crystal ball for this prediction. It doubled three times in 2020. Doubling from where it is today (100% increase) takes it to $1300. A 200% increase takes it to nearly $2000. I hope to see it at those levels some day but I do not expect it to be at...
  16. These Off-Grid, Luxury Travel Trailers Pack Enough Oomph to Power a Tesla Cybertruck

    I'm afraid I only have bad news here. First off this trailer does not have enough oomph to charge your CT. With a 3 kW solar array you might get 18 kWh a day out of the sun in a relatively sunny place in summer (which is, presumably, when you'd use it most). If all that went to charging the CT...
  17. What will it typically cost to recharge a dual motor at a Tesla charging station?

    J1772 is for Level 2. CCS combines (C) J1772 with DC fast charging via a separate set of pins. Tesla chargers incorporate some of the provisions of the earlier CCS standard but not those of the revised. Thus a CCS to Tesla adapter has to translate CCS to Tesla protocol just as the CHAdeMO...
  18. Wiring harness for towing

    It will certainly have the standard plug at the hitch end. It may or may not have a connector in the cab depending on whether it has a brake controller built in.
  19. Travel Trailer will charge my Cybertruck

    Yes. That's what I thought you wanted to do. Not really. That's probably going to turn out to be a quarter of a tankful worth 150 miles without the trailer and probaly 60 with it. What charges this battery? So you are going to burn fossil fuel to produce electricity which you are going to use...
  20. Travel Trailer will charge my Cybertruck

    You should be asking lots of questions about charging your CT too. If you go with the maximum solar package (as I understand it) you will get 2640W of solar. That's not a whole lot in terms of what you need to charge a CT. If you stop in the middle of the day in a sunny spot in the summer and...
