25 years of expertise in the battery industry

Thanks to more than 20 years of expertise with the Lithium-Ion technology, Airbus has developed its own battery products for Space applications since 2016. Equipped with COTS cells, fully qualified by Airbus for Space, they offer a competitive price while maintaining a high level of reliability. Their design is based on a modular approach in order to cope with specific mission requirements while minimizing the non-recurring costs and battery mass.

Airbus acts not only as design authority but also as manufacturing authority, with a dedicated Battery Assembly Line, equipped with automated machines improving quality, lead time and production capacity.

4 product lines are currently addressed with Airbus off the shelf batteries: GEO/MEO telecommunication and navigation systems; LEO optical and radar missions; LEO constellations and launchers.

Thanks to its successful in-orbit heritage, Airbus now stands as a key actor in the Space battery industry.

ESA’s FORUM satellite

Airbus ASTRO-BATT battery product in its 30V configuration has been selected for this mission, proof of the confidence granted by major space stakeholders.

The battery is planned to be delivered in Q1 2025. FORUM is scheduled to be launched in 2027 on a Vega-C rocket from Europe's Spaceport in Kourou, French Guiana.

COSMO-BATT, for GEO, MEO Telecom & Navigation satellites

COSMO-BATT is a Space Equipment product line specifically developed for Telecom and Navigation satellites.

The design is based on a modular approach in order to cope with specific mission requirements while minimizing the non-recurring costs and battery mass. A single module’s energy ranges from 500 to 3000 Wh.

Equipped with COTS Lithium-ion cells, fully qualified by Airbus for Space applications, COSMO-BATT offers a disruptive price in comparison to existing products in an equivalent configuration, while maintaining a high level of reliability.

The modules are delivered by Airbus in a battery pack. Several modules are connected in series in order to reach the targeted voltage and mounted on a spacecraft panel. The battery pack also includes interconnection elements, harness as well as necessary management and safety equipment.

STELLAR-BATT-S

STELLAR-BATT-S is a 30V battery offering around 1700 Wh, designed for an external mounting configuration, thermally insulated from the spacecraft. The module embeds its own radiator.
 

STELLAR-BATT-L

STELLAR-BATT-L is a 30V battery offering from 900 to 3600 Wh thanks to a modular design. Unit thermal management is ensured by a direct contact between unit baseplate and spacecraft panel.
 

A strong flight heritage 

More than 800 STELLAR-BATT battery modules have been manufactured on the Battery Assembly Line. This product was selected in the frame of the OneWeb satellites constellation, with more than 630 satellites in orbits since the first launch in February 2019, ending in an impressive 2000 years cumulated lifetime.

 

LAUNCHER-BATT, a battery product line for launchers

LAUNCHER-BATT is a Space Equipment product line specifically developed to address the launchers market. 

It offers the best compromise between mechanical performance, safety and reliability, all necessary for the success of launchers missions. The batteries can be used for launcher’s units power supply or to power source the pyrotechnics orders for example. Each module can be used in standalone or in series/parallel with other modules.

This module is based on a simple design, using COTS Lithium-ion cells, fully qualified by Airbus for launcher applications, leading to a very competitive price proposal. Each module embeds fuses, in order to ensure safety under all conditions.
