Next-generation ELEO battery technology

Yanmar Group company, ELEO Technologies B.V, a battery technology manufacturer located in Helmond, the Netherlands, will display its next generation of battery systems at Conexpo in Las Vegas in March 2023 on Yanmar America’s booth in the at South Hall 2nd Level — S84014. The new system offers increased energy density and ultimate integration flexibility following from the unique modular concept.

Yanmar will establish itself as the all-in-one systems integrator for smart electrified power solutions tailored to the application-specific needs of individual OEMs. In its capacity as a systems integrator, Yanmar will implement system engineering, design and manufacturing of e-powertrains, while also providing control development, system evaluation, procurement, manufacturing and quality assurance.

As Yanmar transitions to an advanced supplier of electrified solutions, the company remains true to its core values of durability, reliability, quality and robustness, together with the commitment to be a reliable and trusted partner for customers – values the company has lived by for more than 110 years. An important milestone for realising the urgent environmental challenges that we must overcome is Yanmar’s acquisition of battery-technology company ELEO, a fast-growing developer and manufacturer of high-performance modular battery systems. This acquisition will further Yanmar’s electrified powertrain capabilities with versatile, customised solutions for off-road applications.

Ultimate flexibility
The new battery system is the second product generation from the Dutch manufacturer after the first generation started production in early 2020. With the new product, ELEO offers industrial OEMs ultimate flexibility from the scalable design to meet the wide variety of requirements present in the off-highway industry. ELEO’s unique concept features modular battery modules that come in different sizes created from the same tooling, components and production process. This allows for an extensive selection of customised packs without the need for extensive engineering.

By combining a set of modules, the ideal voltage, capacity and dimensions can be reached for any application, ranging from 50-800V and 10-1000kWh in a wide range of shapes. All customised battery systems are provided as full turnkey solutions and are automatically certified according to R10, UN38.3, IEC62619, SIL-2 and designed to comply with R100-3 and a host of others.

Advanced technology
To deliver customers optimal battery performance, ELEO has developed and integrated advanced technology into its new battery system. State-of-the-art cylindrical cells in combination with optimal packing flexibility enable an industry-leading energy density and maximum autonomy. Additionally, ELEO’s unique flexible approach is enabled by its in-house designed Battery Management System (BMS). Each pack has a central pack management unit that collects and controls data from all individual modules, establishing active safety and comprehensive communication to the application. ELEO’s BMS accommodates various communication protocols and features highly accurate estimations for state-of-charge (SOC), state-of-health (SOH), and state-of-power (SOP) while better balancing cells in the battery pack. This affirms that the pack is operating at its full potential while enabling optimal user experience.

To ensure maximum performance under all circumstances, ELEO uses a single-surface cooling method that accommodates both passive and active cooling, minimising temperature differences between all batteries while ensuring maximum performance in both cold and hot environments. Safety has been top priority in the design process. Thermal runaway propagation prevention technology is integrated in each battery system, which means that in the unlikely event a cell goes into thermal runaway, ELEO's proprietary propagation prevention technology assures no thermal runaway propagation will occur and all surrounding cells are protected—limiting damage to a single replaceable module and thoroughly mitigating any safety risks.

Availability
ELEO has already started the production of its new battery system and is ramping up production at its newly built battery production plant at the Automotive Campus in Helmond, the Netherlands. The batteries have been on display during bauma in Munich in October last year and will be introduced to the North American market from March 14-18 at CONEXPO. For both events ELEO joined Yanmar’s booth to highlight the company’s efforts towards the decarbonised powertrain as part of its Yanmar Green Challenge 2050. At its new facility, annual battery production capacity has increased tenfold to 500MWh – equivalent of approximately 10,000 battery packs.

Founded in 2017, ELEO Technologies BV is a fast-growing battery technology company based in Helmond, the Netherlands. Since its inception, ELEO has been committed to the mission of making high quality battery systems accessible to a wide variety of industrial applications. Based on this vision, ELEO develops and produces advanced modular battery packs which are differentiated by their proprietary battery management system (BMS) and innovative thermal management, bringing significant benefits in terms of safety, reliability, and durability.
