Stellantis Debuts ‘Breakthrough’ IBIS EV Battery Tech

Global automaking giants Stellantis recently showed off one of its newest innovations. Called IBIS, short for ’Intelligent Battery Integrated System’, the tech is set to undergo real world testing soon with the automaking giant touting it as a ‘breakthrough.’

“This milestone marks a major step forward in the electrification of mobile and stationary energy applications,” Stellantis said in its press release detailing the new IBIS EV battery tech mentioned.

Firstly, Stellantis had developed IBIS in partnership with TotalEnergies subsidiary Saft. The tech sees both inverter and charger functions embedded directly into the battery, regardless of chemistry and application, using electronic control via 200 transistors.

One of the most innovative features of IBIS is that both inverter and charger functions are embedded directly into the battery.

The architecture supports both AC and DC flow to supply energy directly to the motor or grid. Concurrently, the system is also designed to supply the vehicle’s 12-volt network and auxiliary systems primed on board.

Said design sees Stellantis promising several key benefits starting with increased efficiency and performance by up to 10% (based on WLTC cycle) and 15% respectively versus current EV battery tech with the same size.

Next comes the weight and space savings IBIS provides, with Stellantis touting reduction of up to 40 kg for the former and freeing up to 17 litres of volume with the latter. In turn, this should also enable enhanced aerodynamics and design flexibility.

Besides enhanced efficiency and performance, Stellantis also touts substantial weight and space savings, as well as simplified maintenance.

Critically, the IBIS EV battery tech also promises simplified maintenance. Both easier servicing and enhanced potential for second-life battery reuse are being touted, and not just for automotive application, but for stationary application too.

Following its world premiere late last week, Stellantis is set to put this new IBIS EV battery tech through its paces, key amongst which being ‘real world’ tests using a Peugeot e-3008 prototype test-bed.

Stellantis also says the tech could be integrated into its vast portfolio of production models by the end of this decade.
