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. 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.Construction equipmentMaterial handling equipmentSpecial machinesAgricultural applicationsMarineMunicipal vehiclesOur lithium-ion battery modules are used to manufacture mobile charging stations, allowing to quickly start your works with clean energy.With their remarkable energy density, WATTALPS batteries are also well adapted for an integration into cars. Our modular batteries enable to turn IC engine vehicles into fully electric ones or to design new full electric vehicles easily.WATTALPS goal: innovate to make integration of high performance batteries possible in all type of vehicles.Our state-of-the-art energy density modules combined with a modular mechanical concept allows to fit a lot of energy in small spaces.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.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.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’ exclusive technology includes immersed cells for passive safety, best cooling efficiency, high life, fast charge capability, and 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.Long life moduleHigh energy moduleHigh power moduleConnecting 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.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.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.100% of WATTALPS batteries are manufactured in our own French plant using best in class technology to ensure quality and traceability. 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, and traceability of critical components and test at cell and module level. Production capacity is up to 50 MWh/year.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 come 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.WATTALPS CREW: a combination of experienced and talented people for an ambitious industrial activity in Europe. 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 border 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.Matthieu DESBOIS RENAUDIN: 20 years of experience in innovation, product development and management in big groups: IFSTTAR for VALEO, BOSCH, CEA… Matthieu has always been keen on energy issues for mobile vehicles.
