More than fifty Proton M rockets have been launched in the past ten years with battery cells from EAS Batteries. In the meantime, EAS Batteries has produced and delivered more than 10,000 battery cells for this purpose in accordance with the highest quality and safety standards - the latest battery cell set was delivered in the third quarter of 2020.
The flight of the launch vehicle takes place in three stages. The rocket engines produce a high vibration load into the launcher and each stage is separated after use via detonation charges from upper stage. In space, the rocket continues its flight with a different engine technology. Superior resistance for extreme shock and vibration loads as well as ultra high power performance and reliability are the most important requirements for battery cells used in space. "Our battery cells for the Proton M are extremely robust. If the batteries of the first stage land in the Kazakh steppe after separation, our cells will still work," says Michael Deutmeyer, CEO of EAS Batteries. "So far, our EAS Space cells have shown a one hundred percent flawless performance."
Khrunichev uses the Proton M to launch satellites or other payloads from Baikonur into geostationary orbits, some 36,000 kilometres above the Earth. The Proton M is considered to be the launch vehicle with the highest reliability, one of the highest possible payloads and the most launches worldwide to date.
