Leclanché introduces a new generation of lithium-ion battery modules for e-transport vehicles and vessels and unveils a high-volume European module production line

- The new module is compatible with the full range of Leclanché cells - LTO 34Ah, G/NMC 60Ah and G/NMC 65Ah

- The modules are designed to support up to 800A in continuous current and enabling a battery system of up to 1'200V with a functionally safe battery management system (BMS)

- The new modules feature a very-high cycle life of up to 20'000 cycles (LTO) or up to 8'000 cycles (G/NMC) - allowing for significant reductions in total cost of ownership

- The new module production line is planned for a production capacity of up to 500 MWh per year, and further expandable, representing more than six times the production capacity of the previous module generation


YVERDON-LES-BAINS, Switzerland, June 15, 2021 - Leclanché SA (SIX: LECN), one of the world's leading energy storage companies, has developed a new generation of lithium-ion battery modules for energy intensive e-transport applications, such as marine, commercial vehicle and railway, and simultaneously inaugurated a dedicated new production line for their high volume manufacture in Europe.

The new modules, called M3, represent the next generation in Leclanché's module production with an increased energy and power density compared to the company's previous module generation. They feature a very-high cycle life of up to 20'000 cycles (LTO) or up to 8'000 cycles (G/NMC) - allowing for significant reductions in total cost of ownership and making them ideal for commercial applications. The modules are designed for a wide range of current and voltage outputs, going all the way up to 800A continuous current and for battery system voltages of up to 1'200V with its functionally safe BMS. The module and production line have been designed to accept a high level of flexibility in product configurations while maintaining production efficiency and traceability.

The modules are designed for a range of transport vehicles requiring high cycle life in both power and energy configurations and addressing commercial vehicles, rail and marine applications. The higher density G/NMC versions are used in the majority of transport applications whereas the LTO version is typically used where fast opportunity charging is needed such as for certain bus and AGV (Automated Guided Vehicles) applications and in hybrid hydrogen fuel cell systems used in certain trucks and trains.

Leclanché Installs a New European Module Production Line

Leclanché inaugurated its high-volume production line in a new facility close to its current corporate headquarters in Yverdon-Les-Bains. The company will move its corporate headquarters into the same building in Q4 of this year. The state-of-the-art highly automated production line was with the result of a simultaneous engineering process with its partner Comau Spa (Stellantis Group), a leading global provider of industrial automation and robotic systems, based in Turin, Italy.

The line includes the latest technologies in terms of quality and process control setting the foundation for the transition towards Industry 4.0 principles. It will allow Leclanché to produce up to six times its current capacity reaching an output of more than 60'000 modules per year when in full operation. The line is designed to further expand its capacity as the business grows. This positions the company amongst the first major manufacturer to produce both cells and modules at scale in Europe.

"Today's twin milestone is the result of long-term planning, research and development and significant investments enabled by our employees, business partners and stakeholders," said Anil Srivastava, CEO, Leclanché. "We are especially grateful to our clients and business partners who have collaborated with us and pushed us to innovate and deliver this next generation of battery technology which will contribute to the transformation of transportation and energy efficiency, driving the reduction in greenhouse gas emissions."

M3 Modules: Safety and Efficiency are Key Design Elements

Each M3 module is fitted with a functionally safe slave battery management system unit which communicates with a functionally safe master battery management system unit. The BMS provides several advanced energy-saving and safety features:

* It is designed to meet both ASILC and SIL 2 requirements.

* The slave measures cell voltages and temperatures, and runs diagnostics such as open wire detection, reverse polarity protection and self-checks.

* A dual-core processor offers redundancy, and the functionally safe operating system provides reliability by providing built-in memory protection and task management.

* Power management integrated circuits offer stable power.

* Low power consumption during operation and further reduced during sleep mode; and

* Temperature sensors are fitted on alternate cells, providing fast and accurate response to individual cell temperature variations while ensuring a high level of safety and precise monitoring of temperature distribution for an optimisation of the module lifespan.

The M3 modules are designed to be fully compliant with the relevant transport certification standards for battery modules (selected configurations). For more information, visit contact Leclanché at
