    Full EV's already regenerate from motor braking, very little though.
    Your idea is wrong because the resistance of the electric motor is so strong, you basically don't use the regular (caliper) brake system and the RV would consume much more energy towing an EV "in gear".
    The RV's alternator isn't capable of creating enough power for the RV's electric system and charging another car's batteries. Even if you took a huge alternator, you'd be taking too much energy from the RV engine to power everything.
    Solar panels curently aren't able to charge EV batteries efficiently enough, even if the RV was covered in panels.

    You're trying to produce lots of evergy from little energy, but ignoring many basic laws of physics.

      you could easily charge an electric vehicle off a diesel pusher RV. it all depends on the rate of charge. 120-150A 12VDC/12A 120VAC is easily obtainable from such a system.
      many of those have dual alts anyways, to handle all the accessory loads - and I can run my house in an emergency via my 1500W pure sine inverter - running off an idling M20 - with a 95A alternator and the car battery. Not once has that cause me any grief, and it's much, much quieter than our 4kW brigs genset.
      modern alternators are in the 150-200A output range, (2-2.8kW), and if you've got a dual alt setup, you can basically run whatever you want. it'd be more efficient to charge the battery vehicle via electricity than by wheel drag though - you're then adding in drivetrain loss twice, which even sounds dumb.
      Taking too much from the engine to power everything? that's nonsense. You only need to draw around 6hp off the belt to put out 4kW. Most RV's have over 300HP easy, you won't notice another 6... And even with the efficiency loss of the conversion (M to E), a good diesel is only 40% efficient, while battery to wheel efficiency is in the mid to upper 80s, last I checked.

        GM Volt Beats Plug-In Prius, Leaf In U.S. Rechargeable-Car Sales

        Sales through May are 7,057 - nearly reaching in five months how many were sold in 2011 (7,671). Leaf sales YTD are 2,613.

        Deliveries of the GM plug-in sedan more than tripled to 1,680 units from 481 a year earlier. Toyota sold 1,086 of the Prius version, introduced in March, and Leaf sales slid 55 percent to 510 cars, the companies reported today
        I actually rode in a Prius for the first time when going to lunch. What a piece of garbage. The Volt is indeed much sleeker and has great acceleration and has a much nicer interior. (Plus the better platform, even vs the plug-in Prius)

          Lets get what we really want in a hybrid - 6 speed manual diesel jetta 4motion wagon. if the 2WD version gets 45mpg+ without being a hybrid... I'm thinking upper 50s low 60s for the hybrid diesel version.
          Or an ActiveHybrid 335d xdrive (with quaife/torsens), and a 6 speed manual. Eat your heart out iX.

          c'mon germans! fucking make that shit! make something COOL.

              not via the regenerative braking.

              via just the wheels spinning while another car is towing it, LIKE regenerative braking.

              Most of the rest of what you said is wrong so why spend my time telling you this. A rv charges a tow trailers batteries while it is towing it, an electric car is no different at all.

              while driving 60 mph, the standard rv type vehicles creates 120 volt 20 amp household plug in power all day, meaning it easily reaches the 12 hour charge and most reach the 4 hour charge rate.

              But a seperate diesel generator, which all large rvs have, 6000w, reaches not only the 220 volt charge time it reachs the 440 volt charge time.

              the only thing I even wrote about thats not totally available today is the electric car that generates its own power while being towed. That seems easy but its not necessary.

              Most everything else you said shows you dont know anything about rvs, tow vehicles etc, Im not going to flame you.
              Whereas youre discussing ti with people who do

              as far as solor panels thats just to help. might make a ride a month from a boondocked rv. What would charge the car from boondocked rv is either the rvs engine or a diesel of propane generator. so the smart car would have to come back from down with diesel. Or in town theres one of the electric filling stations.


              As far as the rv im talking about, its basically just any rv capable or towing a smart car.

              bigger is better but im not thinking of a diesel pusher. Im thinking of a mercedes diesel sprinter based. The most effecient vehicle that could do it.

              Even my toyota dolphin could do it it just couldnt reach freeway speeds. Tberes no need for semi truck alternators my toyota alternator can charge an electric car in 12 hours.

              What you need is the backup generator for when it stops because you cant drive 12 hours a day to try and save fuel...

                Drag on the wheels produce by a generator is a braking force. Tomato Tomato.

                the what now? NEC doesn't even allow 480V in residential buildings (max 125V from hot to ground - 250V is opposing 125V lines, still 125V to ground), nevermind talking the power company into giving it to you. Is A 250V 50A outlet (12,500W) not enough to play with?

                it is easy. It's unnecessarily inefficient. if you were dolly/flat towing your race car with an axle driven alternator, you could charge a regular battery, but why on earth would you tow something to charge it?

                solar panels are good for preventing flat batteries - and throwing a set mounted flat on an RV roof isn't going to hurt anything - maybe run a few laptops and an LCD TV, but it's not gonna do much else.

                  u3b3rg33k - Fusion was right... dude just doesn't understand physics / efficiency





                  People realized you could tow a Leaf easily to recharge it, but it's not necessarily smart. Why not just put a generator in the car to re-charge the batteries if you run out?

                    Im almost positive there are no people with average iq even watching this thread so Im not going to introduce more imbeciles to google.

                    later.


                    my favorite physics experts are 3 teenagers who live with their parents telling me who has an advanced degree I dont understand whats already being done with ev vehicles.

                    the nissan leaf will bring out an rv towing modification in the near future. It aparently charges the battery within an hour.

                    pretty well known by people who know what theyre talking about lol. All over.

                    aparently would recharge the leaf within 30 minutes.

                    until then you have a line from the tow vehicles alternator that charges within 12 hours

                    or a line from the rvs generator that recharges within 4.

                    not knowing what youre talking about doesnt bother me but not even looking anything up produces a long life of sad bullshit and worthless conversations that block your own education.

                    There are electric tow vehicles all over the country its big. This idea is hot and its in the near future. towing an electric vehicle to its capacity within an hour will be on many cars within a year or so

                          I googled their L1 and L2 chargers.
                          L1 assumes a standard 15A circuit (note - virtually ALL industrial/commercial 125V outlets are on 20A circuits, even if the electricians are cheap and install 15A outlets). L1 will pull 12A (1500W). L2 will pull 21A from a 30A circuit- or 4x the power (5200W double voltage, near double amperage). amusingly enough, this is the same as your average dryer.

                          on a 20A circuit, you're allowed around 16A draw (in austria, standard circuits are 220V, 16A, basically exactly double what the average house has in the US of A), and on a 50A circuit, you're allowed approximately 40A draw, or 10kW - basically double what the 220V charger will pull.

                          Insofar as the HVDC charging is concerned, nissan recommends against regular fast charging - as it increases the rate at which the battery decays.

                          Towing seems to be a dumb way to charge a vehicle outside of absolute necessity. an IC gas engine is at best 33% efficient (converting fuel to mechanical motion), call it 30% supplied to the transmission, and then you have to remove drivetrain loss and wheel to road to wheel to generator loss as well.

                          There is merit to a solid tow bar charging tow however - AAA would be able to offer a "tow you to work" or "tow your dumb ass home from the mall" when you forget to plug the car in and it refuses to move, and give you some charge in the process - it would likely combine the "5 gallons of gas" and "100 mile no charge tow" option that I have now. that way they'd at least have enough charge to drive into the parking garage / house garage.

                            ya towing the vehicle as it already is works

                            isnt the best or safest way.

                            the next generation will be modified so it is safer and more effecient. Your theories on it, and reality, are still a bit distant.
                            The brakes dont have to be slowing the vehicle down to generate electricity, thats the next generation.

                            I cant say when but the idea is pretty self evident. You dont need to introduce any drag to generate electricity.

                            I cant believe any even highschool grad is confused by this.

                            actually, towing a electric car with a tow truck isnt any different. And that is a good point, in the future, it will happen. A tow will also generate electricity.

                              rw


                              I just reviewed most of your posts in this thread

                              and Im not going to flame you, because you werent even the one arguing with me

                              but your additions to this thread are so stupid I dont even need to point them out. Check out the posts by rw in this thread, his head is 3 feet up his ass and he knows about as much about physics as my fucking cat.

                              youre not in the market for a fucking ev vehicle you dont even understand enough to repeat what you read in newsweek about them.

                              u3 on the other hand is halfway bright, just never actually looked the stuff up.

                              Used his own theories which werent really up to date. then looked up charging circuits. Pretty aware he didnt know and looked stuff up.

                              Couldnt expect anyone else to do anything different.
                              Actually pretty much the same as me.

                              I actually own an rv, and this subject has been chatted about a lot by more educated people in some of the rv forums I check out, so I looked most of the facts up before I went to share it with you all.

                              this is Im pretty sure the only place in the world where people are discussing how towing an electric vehicle cant recharge it.

                                I want to know why like discussions on technology on r3v board are in a hard to reach subforum? I mean, I obviously see why, flaming idiots with forum pictures talking about stupid shit.

                                Whats so stupid about old bmw owners that they cant even share what they learned, they just flame eachother like little imbeciles?

                                I swear I check out my honda civic and toyota truck forum and once in a great while now come here and theres none of this bullshit there.
