  1. EVGo gets $1B loan guarantee from DOE

  2. R1T Max Pack powering my house, thanks Hurricane Helene

    Wow. My 2-bed townhome averages about 300kWh a month not including charging the EV. Our water heater is gas though and only two adults. I saw an interesting statistic that most people use much more energy for heating water than they need for driving an EV
  3. Tesla chargers and everyone else

    Correct. Other makes have not yet been enabled on the Tesla chargers that do not have a magic dock aside from GM just a couple weeks ago. Tesla is way behind on enabling Polestar, etc. Maybe if the guy at the top didn't fire a chunk of the supercharger team. But then again, when was the last...
  4. NY Times Interview: The Road Ahead for E.V.s with RJ Scaringe [9/25/24]

    To be fair, Rivian is building out the RAN network. I expect the site builds to accelerate now that the Open RAN 1.5 hardware is getting deployed. I've already seen pictures of 3 different Open RAN sites with hardware on the ground.
  5. First Gen 1.5 RAN charging station spotted (Erie, Pennsylvania)

    They are taller with a longer cable to reach the car port locations on different cars. So this RAN will be open to everyone.
  6. Social cost of electric vehicles [ADMIN WARNING: NO POLITICS]

    You should look into the social cost of using oil. It may shock you. From the environmental effects to which countries have the most oil. I'll give you a hint, those countries with the biggest stock piles of oil are not run by people who treat their citizens very well. The textile industry is...
  7. RIVN down 10%

    Say he was granted 800,000 shares annual in RSU which is worth roughly $10 million (much less than GM and Ford CEOs pulling in. I recall Mary B is around $30 million annual total compensation). A quarter of that would be 200,000 shares. 83,333 is just over 40%, so that would cover his taxes on...
  8. RIVN down 10%

    Looks like a basic sell to cover taxes for quarterly RSU grant to me. Rivian is distributing RSUs on a quarterly schedule. They will sell a portion of those RSUs to cover the taxes. At RJs bracket, that's at least 35% of his awarded RSUs being sold.
  9. R1T Desert Racer - next race, California 300 in Barstow, CA October 5th

    Just had another thought. If the battery pack is running too hot during charging, you could spray water on the heat exchangers in the front of the truck to potentially help speed up charging.
  10. R1T Desert Racer - next race, California 300 in Barstow, CA October 5th

    What would be an interesting twist was if the rules required equal energy usage... energy content of gas used in kWh vs battery consumption. Or some time of scaling factor. Finish time multiplied by energy consumption.
  11. R1T Desert Racer - next race, California 300 in Barstow, CA October 5th

    Might need some help from Rivian on making sure you can get a charger at Barstow. Barstow tends to get busy on the weekends with Vegas traffic.
  12. Fast Charging Failure

    L1 and L2 use AC charging. Different modules than high power L3 which uses DC.
  13. Batteries heating up to 105 degrees when charging

    As a generalization, 60-65C is typically when things get derated in power for li-ion batteries. 70C is a hard stop. 105F/40C is completely normal and safe.
  14. Charging Rate Drops After an Hour…

    Typically, a derate is because the pins are getting too hot. Either in the charging connector or the vehicle inlet port. This is for safety as the alternative would be something potentially catching on fire.
  15. Motor Heat while DC FAST CHARGING

    Yup, the system was heating up the motors in order to heat up the battery to enable the battery to accept more power.
  16. Sarah O'Brien (Chief Communication Officer) no longer on "Our Company" page

    I don't think that's particularly a bad thing.... The quality coming out of the plant is still not good enough based on all the issues reported by people picking up new vehicles and rightfully asking the service centers to fix things before taking delivery.
  17. EA days are numbered for me

    This makes sense. Really, they limit the current. So double the voltage, can get double the power at the same current derate. With a failed cable cooling system, they can only push so much current through the cable without melting it completely.
  18. EA days are numbered for me

    Typically, anything under 50kW is a derate due to cable cooling system failure. Makes sense other vehicles would see the same issues.
