    Rivian Files Patent For Auxiliary Battery

      Large bed-mounted battery would boost range.

    The Rivian R1T and Rivian R1S were both shown at the LA Auto Show in November, both claiming a top of the line range of 400 miles. The folks over at Rivian Forums have uncovered a patent filing for an extended battery for the Rivian R1T.

    The drawing shows a bed mounted battery with connections for coolant and electrical flow. In addition to providing more energy, the R1T would detect when the auxiliary battery was installed and adjust braking, suspension, and steering to compensate for the extra weight.

    Rivian uses a skateboard style architecture which places the entire powertrain and battery system in a platform below the vehicle and then builds the body on top of it. This allows Rivian to have nearly a free hand in designing the body and interior above the powertrain. 

    Rivian will offer 3 standard battery packs for the R1T:

    • 105-kWh: 402 horsepower, and 413 lb-ft of torque, range of 230+ miles
    • 135-kWh: 754 horsepower, and 826 lb-ft of torque, range of 300+ miles
    • 180-kWh: 700 horsepower, and 826 lb-ft of torque, range of 400+ miles

    Rivian claims the R1T will get 80 percent charge in just 15 minutes when using a DC fast charger and a full charge in eight hours using a Level 2 charger.

    Rivian says the R1T will begin at $61,500 after Federal Tax credit - likely putting the base at just under $70,000. Production is expected to begin in late 2020 at a plant in Normal, Illinois. The company recently landed $700M in investment commitments, lead by a significant investment by Amazon.

    That is cool, just like a aux fuel tank for fueling tractors or a tool chest, having it sit in the bed with the power to tow, that would be a smart add on for 5th wheel / trailer towing.

    Wonder what the added range is?

    I don't think these will 5th wheel tow. They're rated for 10,000lbs max.

    Agreed, not a 5th wheel right away, but I could see a HD version of their skateboard concept doing that and this aux battery pack adding the much needed juice.

    They're not going to do an HD version anytime soon. Other crossovers are coming first.

    If GM got the rights to use it, I could see them take the Skateboard platform and spread it across the whole family. Then maybe if the contract was done for reverse use, Rivian could pick up the HD version that GM applied to it and use it.

    Course I love to Dream of where we will go with EVs. :D

    A 2 seat crossover EV coupe would be an ideal Corvette variation...

      GM News: GM Teaming with Bechtel To Deploy Widespread Fast-Charging Station Network
      By Drew Dowdell
      General Motors and Bechtel are teaming up to form a new company to deploy a widespread fast-charging network. Neither company plans to put any money into the project, outside investors are being solicited.  The network will help General Motors, which plans to introduce 20 new EVs by 2023.  It will also help other manufacturers of EVs. 
      General Motors will provide data to help decide where to locate the EV charging stations and Bechtel will use its own experts for the engineering and building of the stations. Much of the data will come from GM's OnStar system to help learn where people tend to park.  Data from both electric and gasoline powered vehicles will be used.
      Additional fast-charging infrastructure is seen as a requirement to increasing electric vehicle sales. According to a survey by AAA, one of the biggest concerns Americans have about EVs is having enough locations to charge them.  
      The network built by Bechtel and GM will not be limited to interstate highways where most fast charging stations have been located so far.  The company will also locate chargers in urban areas targeting apartments and condos where drivers cannot have a home charger of their own. 
      The new venture joins major initiatives from Electrify America, a Volkswagen funded EV station program, and Tesla with Supercharging, to build out a nationwide network of charging stations.

      VW News: Reservations Open for Volkswagen ID.3
      By Drew Dowdell
      Drivers in Europe can now place deposits for Volkswagen's new ID.3 all electric vehicle.  This is the car that Volkswagen expects to compete with the Tesla Model 3 in the compact EV space. The target starting price for the ID.3 is under €30,000 which translates to $33,585 at the time of this writing. Initial vehicles offered will be special edition ID.3 1st. With an initial run of 30,000 vehicles, the ID.3 1st starts around €40,000 ($44.803) and comes equipped with voice control, navigation system, larger wheels.  There is also an ID.3 1st Plus that ads IQ Light and bi-color design while a Max adds a panoramic glass roof and an advanced heads-up display. 
      The 3 in the name ID.3 marks the vehicle's importance to Volkswagen's history as the most important vehicle after the Beetle and Golf, and also signifies the ability for VW to expand the ID brand in either direction.
      The entry level ID.3 can travel up to 205 miles on a single charge while mid-grade can go 261 miles and top-line models get as far as 342 miles. 
      Volkswagen expect production to start in late 2019 with initial deliveries happening in mid-2020. No word yet on when the model will hit US shores.
