GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

GM, Pilot will build EVgo fast chargers at 500 truck stops across U.S.

All of our maps showing electric vehicle charging stations across the U.S. are going to need an update. Today, General Motors, Pilot and EVgo announced plans to work together on a nationwide DC fast charging network. The plan calls for 2,000 charging stalls that can deliver up to 350 kW to be installed at up to 500 Pilot and Flying J travel centers in the U.S. The goal is to have DC fast chargers available in 50-mile intervals across the country. The new charging stations will feature GM's "Ultium Charge 360" branding and "Pilot Flying J" logos but will not be limited to drivers of GM EVs. The plugs will use CCS connectors and be available to anyone. GM EV owners can take advantage of benefits, including the ability to make exclusive reservations, get discounts on charging costs and streamline the charging process with Plug and Charge and in-vehicle apps that can provide real-time charger availability. The first installation phase will take place in 2023, and "the bulk of the installations" should be completed by 2025, EVgo CEO Kathy Zoi said during a conference call with reporters announcing the plan. "We're gonna get going immediately and commence all of that engineering and planning stuff," she said. "We've got a pretty orderly plan." Pilot CEO Shameek Konar said the company expects the new EV charging stations to coexist with the current fuel infrastructure. "An average Pilot Flying J location is about 10 acres," Konar said. "This will be in addition to all of our gas pumps. The way I think about it is, this is a new source of energy that is going to coexist with gas for quite some time. We can debate how long, but we need to serve both groups of customers." Installing DC fast chargers at hundreds of Pilot's travel centers — aka truck stops — means there should be food, drinks, restrooms, WiFi and even showers available while you wait for an EV to charge. Pilot recently announced its “New Horizons” plan that will invest $1 billion in upgrading Pilot travel centers with more premium amenities, including expanded seating and lounge areas. While the exact amount of time it will take to charge an EV using these new stations will vary on the EV and its current state of charge, most EVs can refill from a low state of charge to around 80 percent in 20-30 minutes on a fast charger. The new stations are future-proofed to deliver up to 350 kW, a charge rate that few EVs today can handle.

Cadillac Lyriq EV unveiled as brand's first electric vehicle

Your author has already seen it, back in March, and has had to wait until today to show you the new Cadillac Lyriq electric luxury crossover. We were excited about it then, we're still excited about it now, but we'll see if we can maintain that excitement for another two years. After some fanfare, a delay, a name explanation and a bit of teasing, Cadillac has finally taken the wraps off the Lyriq, and we like what we see. The bad news — weÂ’ll get it out of the way right now — is that the Cadillac Lyriq wonÂ’t go on sale until late 2022. Moving on, letÂ’s bask in the photos and video weÂ’ve long awaited, and dig into what we know about the first all-electric Cadillac. First, it will come in two drivetrain configurations: rear-wheel drive and performance all-wheel drive. ItÂ’ll use GMÂ’s new Ultium modular battery technology, giving it a driving range targeting north of 300 miles, plus a center of gravity about 3.9 inches lower than that of the similarly sized Cadillac XT5. It will be capable of "over" 150-kilowatt DC fast charging, with a Level 2 charging rate of up to 19 kW. Cadillac Lyriq View 8 Photos In terms of styling, the Lyriq is a substantial move forward both inside and out — and a lot of it has to do with lighting. On the outside, it gets vertical headlights, plus a bunch of little light-up elements in the grille, include a logo that is animated on startup. In fact, the face will light up as you approach, not unlike a dog seeing its best friend ready to play. We see some more nifty lighting signatures in back that carry on a similar theme with more vertical lights. Inside, the lighting situation gets even more interesting, with another light-up crest on the steering wheel, plus wood veneer over aluminum door panels, all backlit. As for its stance, the Lyriq has a long wheelbase, and rides on 22-inch wheels. At the back, we see a slick vented spoiler hanging over the raked rear glass. The side doors of the Lyriq automatically open with the touch of a button in door handle outlines that are flush with the body. Similarly, they close automatically, slowing down at the end to pull the doors fully shut. We wouldn't be surprised if this doesn't make it to production. Moving around the interior, the curved, 33-inch combination digital driver display and infotainment screen sprawls across the dash. It uses advanced LED technology, and is capable of displaying over a billion colors, according to Cadillac.
