Stellantis On A Quest To Halve Battery Weight In Pursuit Of Lighter EVs Get hold of US

Stellantis is aiming to halve the battery weight in its future EVs to make them comparable with gas-powered automobiles, as per a brand new report. To achieve its goal, the group is working with a number of battery expertise corporations, exploring appropriate chemistries.

On the inauguration of its new Mirafiori Battery Expertise Middle in Turin, Italy, the group’s engineering boss Ned Curic advised Autocar that as we speak’s batteries had been too heavy and that light-weight batteries and environment friendly cell packaging are important transferring ahead.

Present lithium-ion batteries are among the many heaviest parts in EVs, and the heft can adversely have an effect on efficiency, effectivity, and security. For example, a GMC Hummer EV’s battery alone weighs 2,818 kilos, the equal of a Honda Civic.

Earlier in 2023, Stellantis invested in California battery firm Lyten, which is creating light-weight lithium-sulfur batteries. The San Jose-based firm claims a lower material cost, a 60 p.c weight discount, and resistance to thermal runaway.

It has additionally talked about the elimination of nickel, manganese, cobalt, and graphite. Cobalt has well-documented negative human and environmental impacts, and several other corporations are transferring away from it.

Stellantis additionally talked about sodium-ion batteries as a doable various. CATL has developed a first-generation sodium-ion battery and claims a excessive vitality density, quick charging functionality, and improved thermal stability. Chinese language state-owned carmaker Chery is reportedly the first automaker to use CATL’s sodium-ion (Na-ion) batteries.

Stellantis, which is the dad or mum firm of manufacturers like Alfa Romeo, Ram Vehicles, Citroen, Peugeot, Jeep, Dodge, Chrysler, and Fiat amongst others, inaugurated its new $43 million Battery Expertise in Turin final week.

With a footprint of 8,000 sq. meters, the group claims it’s one in all Europe’s largest battery testing and improvement hubs. Staff on the facility will oversee stress checks, sturdiness checks, battery administration system software program improvement and calibration, and teardowns amongst different obligations.

The group can be working with France’s Nationwide Centre For Scientific Analysis (CNRS) and TotalEnergies-owned battery options firm Saft to develop a battery that integrates inverter and charger features throughout the module to unlock house, scale back price, and enhance vary. The obvious resolution known as Clever Battery Built-in System (IBIS), and Stellantis has filed a number of patents for it.

There are myriad experiments underway in battery expertise throughout the globe with the frequent objective of decreasing prices, bettering vitality density, and growing driving vary. We’ll have to attend for just a few years to see if a number of options can resolve the persistent subject of vary anxiousness.
