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 to accelerate its EV strategy — Cadillac could be all-electric by 2025

General Motors will roll out details of an expanded and accelerated electric vehicle strategy on Thursday in an effort to convince investors it can be a serious competitor to Tesla, people familiar with the plans said. GM Chief Executive Mary Barra, who is scheduled to speak at a conference hosted by Barclays, is expected to say the automaker is ready to spend more on electric models by 2025 than the $20 billion previously outlined, the sources said. Supplier sources said previous plans to make the Cadillac brand all-electric by 2030 are being sped up, possibly to 2025, and other sources said that acceleration will be repeated in other brands and in segments such as commercial vans. Asked about the Thursday appearance, a GM spokeswoman called talk of increased spending speculative and declined to give details. The Detroit automaker is also expected to discuss a new timeline for many of the EVs to follow those already identified, such as the GMC Hummer EV pickup and Cadillac Lyriq crossover, people familiar with the plans said. Lyriq (shown above) is slated to go into production in late 2022, but GM officials have been stung by criticism the automaker was bringing the vehicle to market too late, one source said. "The pull-ahead in programs is real and the organization is really doubling down on speeding up product development," the source said. Barra and other GM executives have been signaling the automaker's EV acceleration plans. She said earlier this month GM would boost capital spending over the next three years to speed EV development and was talking with other automakers about partnerships to develop more vehicles using GM's battery technology. Last week, a GM executive said the company had pulled forward the rollout of two "major" EV programs, and GM officials have touted the faster 18-month development time for the Hummer truck. Tesla's soaring market capitalization, and growing pressure from regulators to phase out carbon-emitting engines, has put pressure on established automakers to respond to investors who view their internal combustion lineups as outmoded and doomed in the long run. A critical part of GM's pitch to investors has been its new Ultium batteries, which it estimates will offer an electric driving range of 400 miles or more on a single charge. It is building a battery plant with Korean battery maker LG Chem in northeast Ohio.

New Cadillac ELR ad more educational, less controversial than 'Poolside'

Cadillac's first TV commercial for its ELR plug-in hybrid, Poolside, was a smash hit, in that a lot of people saw and talked about it. The 60-second spot didn't say the car was a plug-in, took potshots at the work ethic of all non-Americans and has raked in over a million views on YouTube (you can add one more here). Caddy's new ELR video will get a lot less media attention, but that's exactly the point. Cadillac claims it was happy with the way actor Neil McDonough strutted his way into the controversial ELR discussion. This time around, though, the coupe gets promoted in a more traditional way: with information about the car and what it can do - you know, drive on electricity, capture braking energy into the battery, go further on gas power when needed, those kinds of things – courtesy of GM's executive chief engineer for electrified vehicles, Pam Fletcher. The tone of the video has not been changed because of the Poolside controversy. David Caldwell, manager of Cadillac communications, tells AutoblogGreen that the new video is not destined for TV and is completely different because it's meant for a different audience. "It doesn't have any direct relation to Poolside," he says. "TV advertising is not necessarily the heart of marketing something like the ELR. Notwithstanding the fact that we had a very thought-provoking ad [laughs]." "We definitely have a need to communicate what the ELR is" - Cadillac's David Caldwell The way you reach out to people via the web is different than the mass-media techniques used in spots like Poolside during big TV events (it aired during the Winter Olympics). The two video spots are different because you need to offer different information in different ways, for example having an ELR website as well as an iPad filled with ELR information at the dealership. For Cadillac, TV is "not going to be the predominant methodology," used to sell the ELR, Caldwell said, "the web is closer to what you need to do to reach people. We definitely have a need to communicate what the ELR is. It's not television advertising at all." Caldwell said a handful of other short videos similar to the new one will go live in the near future, showcasing design and powertrain aspects of the car. Keep an eye out for them – just don't look for them on TV. You can watch the new video below.
