Good bit of updates, if they keep this up until the new hardware lands we could be in for some good surprises.

Scientists explain how bigger does not mean better for electric vehicles during colds by Sayan Sen Image by Blomst via Pixabay A new study by Cornell University researchers, working with Tompkins Consolidated Area Transit (TCAT), has found that electric buses use a lot more energy in cold weather, especially in places like Ithaca, where the roads are hilly and winters can be harsh. TCAT started testing seven battery-electric buses (BEBs) in 2021 as part of a pilot program funded by a federal grant. Over two years, the buses ran on 41 different routes in Tompkins County.However,t the buses had issues during colder months, with lower driving range and performance. To understand why, researchers looked at real-world data and developed what they called “Optimal Temperature Zone” (OTZ) models—these models show how much energy the buses would have used in ideal temperatures between 16°C and 30°C. When temperatures dropped to between −4°C and 0°C, the buses used about 48.0% more energy, including both power used to drive and energy regenerated through braking, compared to OTZ predictions. Even in the wider range of −12°C to 10°C, energy use still jumped by 28.6%. Half of this extra energy went into heating the batteries themselves. These bus batteries work best at about 24°C, so when it’s cold, they need extra power to warm up before the bus can even get moving. The other major factor was the cabin’s heating system, especially on urban routes where doors open and close often, letting in cold air. “With an all-electric vehicle, the battery is the only onboard energy source,” said Max Zhang, senior author of the study and a professor at Cornell. “Everything has to come from it.” The study also found that regenerative braking—the process that lets the battery recharge a bit while the bus slows down—didn’t work as well in cold conditions. One reason is that these bus batteries are huge, about eight times bigger than typical electric car batteries, and it’s harder to keep the temperature even across all the battery cells. To improve the buses' performance in winter, the researchers suggested a few short-term fixes: parking them indoors to keep them warmer, charging batteries while they’re still warm, and reducing the length of time the doors stay open during stops. On a bigger scale, cities might need to rethink their transit infrastructure. That includes checking how many charging stations they have, whether buses can be kept in heated garages, and how to adjust routes and schedules. “You have to try to optimize the schedule of all of the buses and to consider the capability of your infrastructure – how many charging stations you have, and if you have your own garage,” said lead author and PhD student Jintao Gu. The team found that rural routes, which have fewer stops, use less extra energy in cold weather than urban ones. That could help transit agencies decide which routes are better for electric buses during colder months. “One of the lessons we’ve learned is that these buses should be designed for the whole country, including states with colder climates,” said Zhang. “But any lessons are good lessons. This helps us learn as a society and do better.” Source: Cornell University, ScienceDirect This article was generated with some help from AI and reviewed by an editor.

Appears to be 150W PSU (Core Ultra 9) so most power delivery ports wouldn't even support it.

Why not use USB-C to power it?
