Stellantis, Saft unveil battery with integrated inverter, charger functions – pv magazine International


After 4 years of improvement, French-Italian carmaker Stellantis, French battery firm Saft, and French Nationwide Heart for Scientific Analysis (CNRS) unveiled the Clever Battery Built-in System (IBIS), which integrates electrical charger and inverter features. It may be utilized in automotive and stationary storage purposes.

Stellantis, Saft and CNRS developed a prototype IBIS vitality storage battery in a joint company and analysis venture in France. The venture workforce goals to commercialize the Stellantis car expertise earlier than the tip of this decade.

In line with the venture companions, this integration of the inverter and charging features will allow a extra environment friendly and cheaper vitality storage system, which improves the vary and takes up much less house within the automotive.

“The IBIS venture affords the chance to cut back the load of the car and the price of the EV powertrain and car manufacturing, whereas providing a lot of new options,” the companions stated.

IBIS combines digital conversion playing cards that carry out the features of an electrical charger and inverter and is put in nearer to the lithium-ion battery cells. Its management system makes it attainable to feed the AC energy on to the battery and make the AC present for the electrical motor attainable straight from the IBIS.

A demonstrator has been working since final summer time. In line with the companions of the venture, this technique is “a topic of many patents and marks a significant break from {the electrical} vitality conversion techniques used at present.”

The demo venture has turn out to be a check subject for varied technical ideas and management and working features in preparation for automotive and stationary purposes.

The companions of the IBIS venture at the moment are targeted on creating a completely useful prototype car, which will probably be examined by the Stellantis improvement financial institution and check tracts in addition to on open roads.

Within the subject of stationary vitality storage and renewable vitality integration, IBIS expertise allows Saft to supply “turnkey installations with improved battery availability, optimized use of put in vitality and a smaller footprint.” The intrinsic structure of the IBIS battery will enable for simplified upkeep and upgrades, in line with the venture companions.

The IBIS venture is funded by the Future Funding Plan, managed by the French Setting and Power Administration Company (ADEME) and coordinated by Stellantis.

Saft, E2CAD and Sherpa Engineering are concerned as industrial companions within the venture, along with the CNRS analysis laboratories GeePs, SATIE, LEPMI, and Institut Lafayette.
