ENERGY STORAGE SOLUTIONS

Advanced Lithium Power Systems

Our mission : to make high performance batteries affordable for your application.

A modular battery system designed for small and medium series : more cost effective, more flexible and faster to implement.

A modular battery system designed for small and medium series : more cost effective, more flexible and faster to implement.

Would it be for a full electric or a fuel cell hybrid application, all vehicle and machine manufacturers have access to a simple and efficient solution for clean power.

Each vehicle type requires a minimum of engineering work depending on the needed performance and work environment. WATTALPS solution requires only a few weeks of engineering for implementation. The R&D phase is thus considerably reduced.

WATTALPS batteries being modular, integrators can capitalize on their developments on their whole product range and therefore significantly improve their return on investment.

A modular offer to reduce cost and time-to-market

Our battery systems are composed of a set of assembled standard bricks to offer you high performance solutions adapted to your constraints and to avoid specific developments.

Premium liquid cooling

Whatever your region or climate, from very cold to very hot (-20°C / +45°C), our temperature control technology ensures optimal performances in all conditions.

Battery recycling at the end of life

The recycling of lithium batteries is a key driver of clean power development. WATTALPS commits to recycle at its expense all the batteries that the company puts on the market.

WATTALPS technology is protected by several patents.

WATTALPS’ exclusive technology

Immersed cells for :

  • Passive safety
  • Best cooling efficiency
  • High life
  • Fast charge capability
  • Cell protection (IP67, IP6K9K)

WATTALPS supplies the battery with a turnkey thermal kit.

Our system is composed of three elementary « bricks » which can be freely combined allowing multiple configurations.

WATTALPS’ goal is to offer a range of standard and modular products so as to make their integration into vehicles or charging stations faster, more efficient and more cost effective. Custom developments of specific auxiliaries can be studied upon request.

The lithium battery modules

We offer several types of battery modules, all fitting in the same casing, with the same interface, which can be split in 3 families:

  • Long life module
  • High energy module
  • High power module
Technical sheet.pdf

Connecting these modules in series or parallel allows for batteries with a voltage ranging from 48 V up to 1,000 V. The energy density of our modules positions our battery at the edge of the technology by approaching 300 Wh/L.

Thermal
regulation system

This « brick » controls and optimizes battery temperature in order to improve life, safety and performance. This system can be chosen in three different configurations. A base sub-system ensures homogeneous temperature in the battery system and can be completed by a heating sub-system or a heating/cooling sub-system depending on the climatic constraints to fulfill.

BMS and battery
junction box

This « brick » is the central control unit of the battery which includes power connections communication and safety control. It also includes current management (current sensor, isolation check, contactors, fuse…). It is available in two configurations for low and high voltage applications.

Production plant

100% of WATTALPS batteries are manufactured in our own French plant

Industrial welding robot : best in class technology to ensure quality and traceability.

High quality module manufacturing :

  • Cells from best in class quality suppliers with stock in Europe
  • Parts from qualified european suppliers
  • 7 discriminative testing steps done for 100% of our production
  • Traceability of critical components and test at cell and module level

Production capacity : up to 50 MWh/year.

Design and process: an automotive quality manufacturing process

Assembled in France WATTALPS high performance batteries are equipped with standard cells manufactured in very high quantity (18650 – the mostly used format). In this format, most of the cell chemistries are available and comes from renowned Asian manufacturers (mainly Korean and Japanese). The customer has the insurance to always have access to state-of-the-art performance.

The thermal regulation of the battery has been developed with the know-how and expertise of CEA, a famous French Technology Research Institute. It is combined with a high-end safety electronic system coming from the famous German Technology Research Institute, Fraunhofer IISB. These two technologies and a rigorous product development ensure optimal life and high safety in all circumstances.

Fulfilling automotive regulations, a special attention is given to the manufacturing of the batteries to make this product reliable.

Manuel RONCO, Matthieu DESBOIS-RENAUDIN, Jean-Noël CARMINATI.

Our energy and our know-how to serve our industrial partners and our society

With a 45 years cumulated experience in design, manufacturing and use of batteries, in mechanical, electrical and electronical systems, the three partners of WATTALPS form a very complementary team.

They also gather the cultures of three countries at the boarder of the Alps (France, Germany and Italy). They maintain a “crew” spirit to get the best of their competences and energies. The “ALPS” particle in the brand name WATTALPS refers to the mountaineering roots, symbol of will, commitment and solidarity to come through the hardest challenges.

The objective is to build a cleaner industry with a great respect of citizen needs (pollution, noise). It is embodied by strong commitments like recycling 100% of the lithium batteries sold by the company.
