French Manufacturer of Lithium Batteries for Industrial Projects and Energy Autonomy Solutions

Custom Design and Manufacturing of Lithium Batteries

TYVA Energie designs and manufactures lithium batteries in France for industrial applications, electric mobility, robotics, defense, maritime, aerospace, and energy storage. From our production facility in Annonay, Ardèche, we support industrial companies in the development of reliable, high-performance lithium batteries tailored to the specific requirements of their products. Our approach combines electronic expertise, industrial know-how, and patented modular technologies to reduce development lead times, lower engineering costs, and accelerate the time-to-market of your equipment.

A company committed to a more sustainable energy future

Why Choose a French Lithium Battery Manufacturer?

Choosing a French manufacturer provides close technical and industrial proximity throughout the entire project. At TYVA Energie, engineering, prototyping, and production teams work on the same site to ensure maximum responsiveness. Our clients benefit from:

a single technical point of contact;
reduced logistics lead times;
improved quality control;
full traceability of components;
personalized support throughout the entire product lifecycle.

Thanks to our regional network of industrial partners, nearly 80% of mechanical and electronic components are sourced locally.

Custom Lithium Batteries: A Unique Modular Approach

Unlike traditional development processes that require designing a completely new battery for each project, TYVA Energie relies on standardized and patented technological building blocks.

This modular approach enables:

significant reduction in development costs;
faster prototyping phases;
more reliable certification processes;
optimized performance;
battery geometry customization according to end-product constraints.

It also enables simple and fast integration of different cell types and battery chemistries, including lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and lithium polymer (Li-Po) technologies, in order to precisely match each application’s technical, energy, and economic requirements. This flexibility also makes it possible to optimize the system’s energy density by selecting the most suitable cells based on weight, space, and autonomy constraints of the final product.

TYVA Energie offers three modular battery ranges: Flat & Kube, Moduloo Ax & Bx, and Moduloo 3D. These solutions can be used as standard batteries, assembled in series and parallel to increase voltage or capacity, or customized to meet the specific constraints of each application.

Thanks to this modular architecture, it is possible to quickly design high-performance lithium batteries offering an excellent balance between energy density, power, and lifespan, while maintaining strong integration flexibility for industrial equipment, vehicles, or energy storage systems.

From Prototype to Mass Production

Our solutions are designed for both prototypes and small to medium industrial production runs. We support our clients at every stage:

Needs analysis Definition of mechanical, electrical, environmental, and regulatory constraints.
Design Cell selection, electrical architecture definition, BMS integration, and performance validation.
Prototyping Rapid development of functional prototypes to validate the product before industrialization.
Production Industrial assembly on our automated line ensuring quality, repeatability, and traceability.

A Robotized Production Line Ensuring Quality and Performance

To ensure reliable and reproducible manufacturing, TYVA Energie relies on a robotized production line dedicated to lithium battery assembly. This automation enables precise control of critical operations such as welding, module assembly, and quality inspections throughout the entire manufacturing process. The benefits for our customers are numerous:

consistent quality from one battery to another;
full traceability of production operations;
reduced risk of human error;
easier scale-up for industrial production runs;
enhanced control of performance and safety.

This industrial capability allows us to efficiently support the transition from prototype to mass production while maintaining a high level of quality standards.

Certifications and Regulatory Compliance

TYVA Energie batteries meet the requirements of the most demanding professional applications. Our solutions can integrate or comply with the following standards: UN 38.3, CE, RoHS, IEC 62133-2, IEC 62619, IEC 62660, UNECE R100, UNECE R10.

Industrial Applications

Autonomous Power Stations

TYVA Energie also develops portable power stations designed for professionals in construction, events, audiovisual production, and off-grid applications.

These solutions effectively replace traditional diesel generators thanks to:

silent power supply;
no direct emissions;
high available power;
compatibility with solar panels;
simplified maintenance.

Choosing a Lithium Battery Manufacturer

Why Choose TYVA Energie?

French manufacturer since 2013
Industry 4.0 factory located in Annonay
ISO 9001 certification
Patented technologies
Refurbishable solutions thanks to TYVA Refill
Full technical support
Recognized expertise in demanding industrial sectors

Why is TYVA Energie the ideal partner for producing small and medium battery series?

Choosing a partner for production runs of 100 to 1,000 units is a strategic challenge: large automotive manufacturers are not interested (volumes are too low), while small assemblers often lack industrial quality guarantees.

Here is why TYVA Energie positions itself as the ideal partner for this type of project:

1. The Industrial “LEGO” Advantage (Moduloo)

Most manufacturers impose significant non-recurring engineering (NRE) costs to design a fully custom battery. TYVA uses a modular approach with solutions such as the Moduloo Ax range.

No unnecessary “research”: we use pre-certified technological building blocks.
Adaptability: modules can be assembled in series or parallel to reach the required voltage (V) and capacity (Ah) without redesigning the entire electronics.
Cost efficiency: for 500 units, you benefit from a cost structure close to mass production without paying heavy engineering budgets for a fully custom design.

2. A French Factory Designed for Flexibility

Their production site in Annonay is not a simple assembly line, but a robotized Industry 4.0 factory.

Consistent precision: cell assembly is automated, ensuring that the first and the 1,000th battery are strictly identical.
Responsiveness: unlike an overseas supplier, lead times are reduced and communication is direct with the engineers who designed the product.

3. Mastering “Early Failure” through Eco-Design

This is a key advantage for medium production runs: the TYVA Refill technology.

Repairability: unlike batteries that are impossible to recycle or repair, TYVA solutions allow only end-of-life cells or faulty components to be replaced.
Longevity: knowing that your battery fleet is maintainable over 10 years provides a major competitive advantage over disposable solutions.

4. The Certification Barrier

Certifying a battery is expensive and time-consuming (UN 38.3 for transport, CE marking, IEC 62133, IEC 62619, etc.).

By relying on TYVA’s pre-tested and pre-certified modules, you significantly reduce the risk of legal issues or of products being blocked at customs or restricted from air/sea transport.
