GM reveals new Ultium batteries and flexible global platform for rapid growth of EV lineup

Green Car Congress

The heart of GM’s strategy is a modular propulsion system and a highly flexible, third-generation global EV platform powered by proprietary Ultium batteries. Motors designed in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications. Photo by Steve Fecht for General Motors).

How to Build EV Motors Without Rare Earth Elements

Cars That Think

Global efforts to combat climate change hinge on pivoting sharply away from fossil fuels. Against this backdrop, massive efforts are underway to design and test advanced electric-vehicle (EV) motors that do not use rare earth elements (or use relatively little of them). The dilemma is easy to describe.

Daimler Trucks E-Mobility Group starts global initiative for electric-truck charging infrastructure

Green Car Congress

The sooner and more exactly the energy suppliers and power grid operators know what customers’ infrastructure requirements will be, the faster and more efficiently they can build them up. Fast processes mean reduced costs for all involved. The third area deals with the optimization of the total cost of ownership (TCO).

StoreDot says its silicon-dominant batteries will enable smaller battery packs capable of extreme fast charging, leading to more accessible EVs

Green Car Congress

StoreDot, the developer of extreme fast charging (XFC) battery technology ( earlier post ), says it will soon be manufacturing silicon-dominant batteries that enable car makers to design and produce cheaper, lighter and more sustainable EVs. When charging times are no longer an issue, it makes a lot more sense to fit smaller battery packs.

Wildcat Discovery Technologies is building a US plant for LFP cathode and next-gen battery materials

Charged EVs

Now the company is building a US plant to produce nickel-free and cobalt-free cathode materials. Now, manufacturers have taken advantage of LFP’s lower fire risk to design batteries with high pack-level energy density, and LFP has become the EV industry’s fastest-growing cathode material. No nickel, no cobalt.

How HummingbirdEV uses modular platforms and micro-factories to lower the cost of commercial EVs

Charged EVs

Hummingbird is addressing several global markets—it has customers in the US, Europe and China, and is now making a major push into India and the GCC (Persian Gulf) region. How do you build a vertically integrated modular vehicle platform that can not only fit the North American market, but can also scale up to growing markets like India?
