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.

The GMC Hummer EV is big and fast; it's also a social conundrum

Pedestrian fatalities, unresolved safety issues, overachieving and overweight trucks — overweight electric trucks — and divisive attitudes about vehicles equipped as is the new Hummer EV, are very much on the mind of Robinson Meyer. Mr. Meyer, who suggests that the 1,000-horsepower pickup is a cross "between an ambulance and a race car," is a staff writer for The Atlantic, a well-respected, long-lived journal founded in 1857. His recent essay in the monthly's flagship magazine starts off describing a scary video clip posted online by Edward Barseghian that features the 9,000-pound Hummer hurtling full tilt towards three lanes of cars idling at a light (the driver stops it in time). Then he goes on to pretty much berate the machine. "The Hummer EV haters and lovers had discovered one of the most important facts about electric 'super trucks': They are very heavy, and they go very fast," he writes. "If you imagine an ambulance that can accelerate as fast as a Formula 1 car, youÂ’re imagining a vehicle only slightly more unwieldy than the new Hummer." Meyer goes on to discuss the issue of allowing battery powered vehicles that weigh as much as the Hummer does onto public roads. "The weight of EVs is a safety issue that drivers — and cyclists and pedestrians — will only have to keep worrying about as these cars go mainstream," he explains. "Suffice it to say that cars as huge as the Hummer EV need to face some kind of regulation, especially in cities and towns, where they pose a distinct threat to the public." To Hummer devotees, them's fightin' words. But Meyer takes pains to present a sort of response from Anthony Schiavo, a research director at Lux Research, a global advisory firm: Why is the Hummer so heavy if its batteries weigh only about 3,000 pounds? “ItÂ’s absolutely a design choice and a marketing choice,” Schiavo answers. “People like larger vehicles, and the reason why those larger vehicles are getting made is because they sell.” The author concludes by bringing into his thesis the issues of climate change, liberal and conservative politics. In some places, his arguments wander; they become muddled. But for those enthused about electrics and big trucks, "Frankenstein's Hummer" is worth a read.
