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.

Recharge Wrap-up: meet the Luka EV project, VisibleTesla allows Model S hacking

Select Registry is partnering with Tesla to install chargers at many of its lodgings. More than 170 hotels, inns and bed & breakfasts will install Tesla High Power Wall Connectors for their guests to use. So far, 63 properties have installed the chargers. Eventually, Select Registry members in 34 states as well as Nova Scotia will offer charging on-site. Tesla's wall charger provides the Model S with 58 miles of range per hour. The hotels will rent you a room for the full night, as well. Read more in the press release below. Tesla Model S owners can hack their car with the VisibleTesla app. The free, open source app allows users to check on and control the status of the car and its subsystems, similar to Tesla's official apps. VisibleTesla can also be used to schedule certain automated commands. For example, its creator, Joe Pasqua, has his car send him a text message reminding him to bring his bags with him when he enters the grocery store parking lot. Other users have the car remind them if the car is not charging at a certain time, or schedule the car to turn on the heat before departure. Read more at TechWorm, or learn more at the VisibleTesla website. Georgia Power has added 32 Chevrolet Volts to its fleet. Employees, particularly the utility's energy efficiency experts, will use the cars to travel to customers' homes and businesses to conduct energy audits. "We are leading by example and demonstrating to our customers, and other Georgia businesses, that electric transportation works for all drivers," says Georgia Power Chairman, President & CEO Paul Bowers. Georgia Power also offers charger rebates and special rates for EV customers. Read more at Domestic Fuel. The Luka EV is a project to build an affordable, lightweight, retro-looking, road-legal electric car in one year. The team wants to get the car certified for use on EU roads by September 2015. They have goals of achieving a driving range of 300 kilometers (about 186 miles), keeping the cost under ˆ20,000 (about $22,280 US at current rates) and the weight under 750 kilograms (about 1,650 pounds). The builders recently completed their first range test of the working vehicle, which uses in-hub motors for propulsion. Learn more at the Luka EV project page on Hackaday.

Chevy Volt has worst sales month since August 2011, Nissan Leaf also down

January is traditionally a time when new car shoppers take a break. For the last few years, if we isolate our focus to just the first two major plug-in cars in the US market, we see that the first month of the year was lower – often dramatically lower – than the 11 that followed. So, when you see the Chevy Volt dropped and Nissan Leaf sales figures for January 2015, don't be too surprised. The Volt sold only 542 units last month, that model's lowest since August 2011. That also represents a 41 percent drop from January 2014, and it reinforces the thought that if anyone out there is interested in a new Volt, they're going to be waiting for the new model to drop later this year. While we do expect sales to climb in February and into spring, we won't be surprised if the general Volt trend remains quiet until the second-generation arrives. On the Leaf side of the ledger, January's low sales numbers were still about twice as high as the Volt's – the Leaf sold 1,070 units last month, the lowest since February 2013 – but it did break a streak for the Japanese automaker. Usually, each month represents at least an increase over the same month a year ago, but that wasn't the case this time. In January 2014, Nissan sold 1,252 Leafs. Still, Brendan Jones, Nissan's director of electric vehicle sales and infrastructure, issued an upbeat statement: "We saw a significant increase in demand in December from Nissan Leaf customers looking to take advantage of federal and state incentives at the end of the tax year, which pulled some sales ahead. We're confident that EV sales will continue to rise over time due to increasing emission regulations and other reasons for purchase of EVs such as lower operating costs, reducing dependence on foreign energy sources, environmental concerns and a great driving experience." The numbers will tell us soon enough. News Source: General Motors, Nissan Green Chevrolet Nissan Electric Hybrid ev sales brendan jones
