    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    Here's a video on Atlis' claimed rapid charge, new battery chemistry and packaging. Competition around batteries, their chemistry, packaging, modularization and management will drive the BEV industry for the foreseeable future. That's the theme of this thread. But it's hard to predict...

    Bidirectional home chargers

    IN CASE THINGS GO BAD In my case and perhaps in the cases of many others, using our Rivians as a backup source of electricity would only occur when things go wrong. Maybe this would happen a couple of times a year when there's an electrical power outage. While it may be inadvisable to use a...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    As you say, Toyota, the Japanese government, Hyundai and the S. Korean government continue to push hydrogen fuel cell technology, but the emphases are on commercial applications, like taxis and trucking, where you can have fleet refueling stations. You start and end your days where hydrogen...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    Here's an interesting piece comparing Hydrogen/fuel cell powered vehicles versus BEVs. It's not surprising battery powered vehicles are more efficient, but the degree of their advantage is surprising. The study looks at energy costs from well-to-tank and tank-to-wheel, claiming that...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    I agree. There's no need to debate Elon vs RJ. Both brilliant but very different. The good news, I think, is the massive worldwide effort in researching and developing the next generations of batteries. Note the plural. There's so much R&D being undertaken in so many different fronts that...

    AJ, good thoughts. You're suggesting a battery backup to my solar system, one that charges and discharges regularly. Then I tap into the storage battery with my Rivian, thereby keeping the Rivian fully charged. All of that makes sense. When power goes down, am I pulling electricity from...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    Musk is notorious for making misleading, exaggerated and self-serving statements. Tesla batteries are among the best, but that doesn't mean only Tesla knows what's going on, especially with respect to battery chemistries. Tesla may be developing/making lower cobalt content batteries but it's...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    Here's a recent article about so-called 811 batteries that use a lot less cobalt, thereby reducing the cost and increasing the longevity of batteries. LG Chem, one of two companies Rivian is reputedly in discussions with (the other being Samsung SDI), leads in this sort of battery chemistry...

    AJ, here's another story about Wallbox, a bi-directional home charger, that won this year's Edison Award. https://cleantechnica.com/2020/03/25/wallbox-bi-directional-charger-wins-coveted-edison-award/ There might be quite a bit of interest in using a Rivian this way. Originally, I thought it...

    Rivian Shuts Down All Facilities to Slow Spread of COVID-19 / Coronavirus

    Aren't the Pantagraph photos of the new 400,000 square foot addition to the existing 2.6 million square foot, former Mitsubishi plant? I think so. It's not surprising Rivian isn't further along. Indeed, without actually knowing anything about how Rivian plans on laying out assembly...

    In Northern California where PG&E is the service provider, electrical outages are (increasingly) common and, for an all-electric household like mine, being able to draw power from a Rivian to power a household is hugely attractive. Heck, even if you have gas or propane to power some or all of...

    I'd wager Amazon will offer home charging solutions for Rivians. It will be offered at the time of purchase, as an option, or as an after sales item.

    Good Forbes Article on Rivian - production number estimates and vehicle servicing mentioned

    Yes, 250K vehicles per year, but Rivian is starting from scratch and not taking over Mitsubishi Motors equipment and transfer lines. So, Rivian has a 2.6 million square foot, former Mitsubishi plant to which it's already added 400K more square feet. Setting up and starting a 3 million square...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    Thanks, DucRider and Ajdelange. You're right. The first Rivian batteries, encompassing hundreds/thousands of decisions with respect chemistry, packaging, manufacturability, repairability, sustainability, logistics and so on, will likely last a good ten years or longer. By the time they're...

    BEV & Battery Wars: Rivian, SDI, GM, Chinese, S. Korean & Global Rivalry

    Thinking more about batteries and, as Rivian enthusiasts, there appears to be 3 or 4 major branching points with respect to battery technology in the early years ahead of the battery electric vehicle (BEV) industry. The first is battery chemistry, the second is how batteries are packaged, the...

    More info on the global competition around battery technology. In general, with government subsidies and promotion and the largest domestic auto market in the world, battery technologies have grown by leaps and bounds, along with vehicle production, in China. In S. Korea, also with...

    The battery wars for BEV technical supremacy are heating up. Here are news flashes to this effect. I used the first to start this thread a month ago, highlighting what GM is doing with its Ultium batteries...

    Possible First Peek at Rivian's Future Rally Model

    It's unclear if the 400,000 square foot added to the 2.6 million square foot former Mitsubishi plant in 2019 was included in the reported $24 million spent in 2019 and the $750 million slated to be spent in 2020. In either case, about $800 million has been earmarked for Normal so far. There's...

    Why are you buying your Rivian?

    Yes, I agree - high volume/high margin is the sweet spot, but it rarely happens. Nonetheless, Tesla may be rewriting the rules of competition in the auto industry even if a half-million units per year doesn't yet put it in high volume territory. Mercedes and BMW each sell 2.3-2.4 million...
