PowerTech will lead the development of a smart and highly scalable BMS for the EEC promoted MARBEL project : “the EV battery of the future”

Our company has been selected and enrolled in a new innovation project led by the European Union. We are proud to participate in the MARBEL project, whose objective is to develop a vehicle battery that meets the acceptance criteria for the future, namely ecodesign, modularity, use of recycled and environmentally friendly materials, additive manufacturing, ultra-fast charging, and last but not least low manufacturing costs.

Our contribution in this project is major since we will be in charge of developing a distributed and ultra-communicating BMS system for the management, control and piloting of this new generation battery.

The ultimate goal of this project is to produce this battery of the future for a car model of the FCA (FIAT-CHRISLER) group from the end of 2024.

This project will start in January 2021 and is financed by the European innovation programme H2020 to the tune of about 11 million euros.

More details of the MARBEL project :

With the goal of accelerating the mass market take-up of ultra-high-performance batteries for battery electric vehicles (BEV) and plug-in hybrids (PHEV), MARBEL project (Manufacturing and Assembly of modular and Reusable Battery for Environment-friendly and Lightweight mobility) will base its approaches, solutions and innovations around the versatility concept as an axis within the entire project. It will focus on the need for fast charging and long-lasting batteries to boost end user demands, while applying high modularity and easy assembly and developing novel testing methodologies for safety, profitability and circularity.

MARBEL will design, develop and demonstrate new modular, compact, lightweight and high-performance battery packs together with flexible and robust battery management systems for these BEV and PHEV, while maintaining safety levels, allowing fast, high quality and cost-effective large-scale production and following the “made by Ecodesign” principles. A set of modules easy to pack together and to disassemble would ease the manufacture and dismantling of different battery configurations sharing the same production process and common elements.

MARBEL will develop and qualify future and innovative performance- and safety-related test procedures of developed functionalities such as the use of miniaturised housings, a flexible test-bench simulating integration-in-EV conditions (electric Vehicle In-the-Loop, eVIL) and artificial intelligence as a tool to reduce the time of laboratory experiments.
MARBEL aims at a triple win, for people, business and planet.
MARBEL is expected to generate scientific and technological impacts, boost the appearance and consolidation of new players (especially SMEs) and business models, reinforce the European position in the global battery market, and contribute to environmental and societal targets.

In addition, MARBEL approach is based on the following pillars:

  • Advanced battery packaging using a Design for Assembly (DfA) and Disassembly (DfD) methodology.
  • Lightweight and sustainable battery packaging.
  • Solutions and processes for the sustainable dismantling and 2nd life.
  • Flexible advanced battery management systems.
  • Ultra-fast charging strategies and enhanced thermal management.
  • Future performance & safety-related test procedures.
  • MARBEL consortium is made of 16 partners from 8 different European countries, representative of the aimed multi-stakeholder collaboration and business drivers required for developing the battery pack of the future.
  • Arkema 4: PowerTech Embeds Kynar® Technology in its battery cells

    Designed for ocean racing, the trimaran Arkema 4 was launched in September to begin its first trials.

    For this new competition trimaran, PowerTech developed very specific servitude batteries, using fluoropolymer separator films in Kynar® technology from the company Arkema.

    This new material has very high resistance characteristics, with an extremely low film thickness. The result is the development of even safer battery cells with a 4% reduction in weight.

    This battery powers the vital equipment of the racing boat. It is recharged via solar panels.

    New high-performance lithium LiFePO4 cells

    Lithium Iron Phosphate - LFP - LiFePO4-cell

    After more than a year of intensive testing, we are now using a new high-performance lithium LiFePO4 cells to replace the cells used in our products.

    This new generation of cell retains all the safety and robustness of those used in our products to date and adds two major improvements:

    • Specific Energy improved by 25% : It is possible to accommodate 1/4 more energy in the same volume.
    • Improved operation life by 50% : Cycling tests performed show a performance of 3000 cycles of full charge-discharge cycles (100% depth of discharge) at 1C. This represents a 50% increase in the number of cycles compared to the previous generation.
      At a DoD of 80% at 1C, the number of cycles performed rises to 4500.

    Below chart shows the estimated number of cycles for our new generation of Lithium LiFePO4 cells, according to the discharge power and DOD figures. The test conditions are those of a laboratory (constant temperature of 25°C, constant charge and discharge power).

    Lithium Iron Phosphate Life Cycle
    Life Cycle chart of new LiFePO4 cell generation

    We can read from the chart the below figures :

    • 3 000 cycles at 100% DoD @ 1C
    • 4 500 cycles at 80% DoD @ 1C
    • 10 000 cycles at 60% DoD @ 1C
    • etc.

    It should be noted that following the number of completed cycles, the cell still have a nominal capacity > 80% of the original capacity.

    Our main product ranges: PowerBrick, PowerRack and PowerModule, will benefit in the coming months from this new generation of cells with an increase in capacity, a reduction in weight but also a significantly improved lifespan.

    The E-mobility market today

    Electro-mobility becomes more democratic

    It is the ability or property for people or objects to move in a space, by a means of transport using partially or totally electrical energy.

    Today, electromobility meets a major challenge in the fight against global warming. That of the replacement of polluting thermal engines by electric models more respectful of the environment.

    According to figures released by the IEA (International Energy Agency), the number of electric cars in circulation around the world has sharply increased in 2016. With more than 750,000 units sold (40% more than the previous year), the market of green vehicles has exceeded the symbolic bar of 2 millions of units.


    Some key figures:

    • China has become the main market for electrically powered cars. With more than 336,000 new registrations, it concentrates more than 40% of global sales in 2016. Moreover, there are 200 million electric two-wheelers and more than 300,000 electric busses.
    • In second place is Europe with more than 215,000 green cars in 2016.
    • In Norway, electric cars account for 1/3 of new car sales.
    • Next come the United Kingdom, France (where electromobility represents only 1.5% of the market share), Germany, Sweden and the Netherlands.
