    Question about EREV Extended Range EVs on Long Trips (Harvester Gas Engine)

    It is more appropriate to express the Harvester output as kW than mph. Using your 70 mph speed example and assuming an efficiency of 2 mi/kWh (non towing) if the Harvester only added 50 mph that would mean its output would be 25kW, which would be pretty anemic for the size vehicle. Scout has...

    Dual fuel

    Not sure how this can be done as you can not simultaneously charge and discharge a battery. Current can only flow one way in a battery.

    Are you still a Scout buyer without $7500 EV tax credit?

    I am still a buyer with no tax credit as long as Scout hits their marks I am not convinced the tax credit is going away either, despite what Trump said.

    Current and future Scout Reservers: Have you cancelled reservation(s) or plans for other EVs?

    I have a ramcharger reservation, seems like they are getting close, not too excited about buying a Stelantis product though, especially with the problems their other EV products have had, probably at least take a look at what the ordering process is, build and price one. With Scout now an...

    Dual fuel

    Except GM (Volt) and BMW (i3) and Nissan (ePower) have already done it this way. The inverter acts like a router for the power coming from the generator. Routing the generator power to the drive motors preferentially, depending on demand, any excess power gets routed to the battery, any...

    Dual fuel

    I‘m no EE so i don‘t know how much more complex it would be, but it would definitely be more efficient. Pretty sure that‘s how the Volt and i3 work and from Rams website ”The generator can also increase the power to the motor and gearbox when serious power is needed.” And with Scout saying...

    Dual fuel

    There is no mechanical connection between the gas engine and the drivetrain-period…but unless I’m mistaken the A/C from the gas engine generator will go directly to the A/C drive motors. Any excess will be converted to D/C and go to charge the battery. Any deficit will be supplied by the battery.

    Harvester EREV analysis & predictions: 3 cylinder gasoline engine, HP output, EV battery pack size, fuel tank location, approach departure angle

    Yes, charging at home is usually cheaper, some people though have very high utility rates. Using my example above a utility rate of $0.40/kWh is the same as gas. We are grid tied solar with 1:1 net metering. Our array covers 95% of our needs, including EV charging. The cost of the...

    Harvester EREV analysis & predictions: 3 cylinder gasoline engine, HP output, EV battery pack size, fuel tank location, approach departure angle

    My Ioniq 5 gets 3.5 mi/kWh on roadtrips, in the summer, IF i keep the speeds down below 70. 2.2-2.5 mi/kWh in winter conditions. EA DC fast charging costs can vary a lot, typical is $0.47/kWh = $0.134/ mile Summer $0.20/mile winter. If my car as an ICE got 30 mpg and gas is $3.50 per gallon =...

    Harvester EREV analysis & predictions: 3 cylinder gasoline engine, HP output, EV battery pack size, fuel tank location, approach departure angle

    With gas at $3-4/G and the DC fast charging rates I’ve seen in the Northeast “fueling” an EV is not necessarily cheaper than fueling an ICE, esp on a road trip, and may not be for home charging either depending on what your utility charges for electricity.

    Harvester EREV analysis & predictions: 3 cylinder gasoline engine, HP output, EV battery pack size, fuel tank location, approach departure angle

    Depends on how much your road tripping hauling a camper. I’ll gladly sacrifice a little mpg on road trips for the efficiency of electric on daily trips and if I have to haul around another power plant to make the road tripping and towing more convenient then so be it. 50% range hit while...

    Current EV owners: are you sticking with full-EV or switching to EREV Harvester Scout?

    Correct, and 100% indicated is not actual, the manufactures build in an upper and lower buffer precisely so that the batteries don’t sit at full capacity.

    Current EV owners: are you sticking with full-EV or switching to EREV Harvester Scout?

    If you do the math on the specs that Ram is giving for the Ramcharger, it’s about 20 mpg when the gas engine is running.

    Current EV owners: are you sticking with full-EV or switching to EREV Harvester Scout?

    We have been all EV for three years now, no complaints. It works well for each of our ~60 mile round trip commute. My work has free charging too, so i only charge occasionally at home. We have had no issues with road trips either aside from occasionally having to wait for a charger. The plans...

    Current EV owners: are you sticking with full-EV or switching to EREV Harvester Scout?

    Question inspired by the stats on the reservation tracking sheet: It'd be interesting to see how “Own an EV” and “Full electric or electric and gas” correlate. If you're an EV owner, please answer the attached poll. And please share what you drive and why you're sticking with full-EV or...

    Harvester EREV analysis & predictions: 3 cylinder gasoline engine, HP output, EV battery pack size, fuel tank location, approach departure angle

    CT, Lightning, R1T, Silverado EV, are all right at 2mi/kWh at 60-70 mph, add a trailer of any size and it goes down to 1 mi/kWh, up an extended grade an it goes down to 0.5 mi/kWh, so a generator needs to be 60kW just to keep up under normal towing mode 120kW under extreme demand add in 10% AC...

    Share memories of your original old Scouts

    I had a buddy in high school who had a Scout, it was a total beater, he loved it but we teased him mercilessly about it. One day we hooked up one of those spark plug firecracker gags so he would think the thing blew up…parking lot full of guys after practice, good memories.

    HVAC heat and AC via heat pump?

    Interesting, this is new to me. It seems as though elastocaloric would have limitations based on ambient temp?…like heat pumps. When the temps get really low the heat pumps can have trouble keeping up, so some resistive back up would be nice, even though it is less efficient.

    Rear air vents needed in Scout production models. Preferred location: floor, B-pillar, center console??

    My preference would be floor for heat and B Pilar for AC, and hopefully the ability to turn on/off based on occupancy.
