Eco-Engineering & OEM Support

COLLABORATION WITH MANUFACTURERS

With our 60 years of combined experience in the lithium battery industry, we have designed, produced, and recycled lithium-ion batteries. This has enabled us to accumulate a wealth of knowledge in the field.

At NOWOS, we believe sustainability is essential from the design phase. With our eco-engineering approach, we are able to collaborate closely with our customers to improve procedures and optimise design for repair in lithium-ion battery systems, as well as advise on spare parts sourcing.

CHALLENGE

  • Roetz Bikes is a Dutch Circular & Sustainable Designer and manufacturer of Bikes. 

  • Roetz approached NOWOS with a need to develop a new sustainable battery solution for their e-bikes. They required detailed specifications for both functional and hardware behavior to ensure the batteries met all necessary standards and performance criteria.

SOLUTION

In 8 months, NOWOS was able to enhance and provide precise guidance to the battery manufacturer, which included:

  • Detailed functional behavior requirements

  • Comprehensive hardware behavior requirements

  • A thorough quality control (QC) process to ensure the final product met Roetz's standards


In addition, NOWOS acted as the technical liaison between Roetz Bikes and the battery manufacturer, ensuring clear communication and that all technical needs were understood and fulfilled.

CASE STUDY: EBEE

CHALLENGE

  • eBee is on a mission to lead the adoption of light-electric vehicles in Africa with the production of 1 million e-bicycles on the road. 

  • eBee asked NOWOS to design a battery that could be maintained and produced in Africa, with the goal of giving the battery a second-life in home energy storage once it reached end-of-life in its primary application.

SOLUTION

In just over a year, NOWOS developed all hardware, software, and mechanical designs in-house to enable the client to manufacture a highly versatile battery including:

  • A modem for remote monitoring and control

  • GPS for live tracking

  • Anti-theft

  • Repairable and reusable for energy storage

  • G-force sensor to monitor mechanical health

  • WiFi and Bluetooth for direct communication with the user

  • Monitoring capabilities to track real-time battery health

BENEFITS TO THE CIRCULAR ECONOMY

The battery is designed for ease of maintenance, repair and production in Africa, which can be repurposed for home energy storage, extending its lifecycle and minimizing waste.

WE CONSULT ON

    • Safety and ageing of cells

  • Testing Processes

We can test cells and the battery management system (BMS) as needed. We can suggest stronger case designs to resist moisture, or help you create a clear battery specification and pick the best configuration. We also test prototypes and recommend design improvements before final approval. The result: an energy-efficient, durable, and easy-to-maintain product.
