We provide comprehensive consulting based on your objectives and develop the right solution
The demands on modern battery systems are as diverse as the industries in which they are used. Whether primary or rechargeable batteries—or our standard product vri BASE LINE—we provide manufacturer-independent, solution-oriented consulting with deep technical expertise. Your application requirements and specific use case are always our primary focus.
Our battery consulting supports you from the initial idea through to series approval—with solid expertise, a clear understanding of standards like the Battery Regulation (EU) 2023/1542, and extensive experience in complex projects. Together, we develop robust battery concepts precisely tailored to your technical, economic, and regulatory requirements.
Whether battery consulting in the early concept phase, targeted advice on battery development, or selection and configuration of suitable cell chemistry—at VRI, you receive consulting with substance. Transparent, efficient, and always practical.
Fully developed and certified—flexibly customizable for you
With vri BASE LINE, we offer you a standardized product family that is ready to use immediately yet customizable to your needs.
The series is based on 18650 and 21700 cell formats—providing a standardized foundation for various configurations and applications. Completed certification saves time, reduces costs, and enables a fast project start without additional licensing procedures. For you, this means less development effort, shorter time-to-market, and full planning reliability.


Battery form factors


Dimensions, weight, performance—the right battery form factor impacts the performance of entire systems. We advise you on selecting and implementing custom, flexible, and precisely sized battery housings and cell arrangements tailored exactly to your application. Our portfolio also includes special formats and meeting specific requirements—for example, in robotic systems, medical devices, or IoT applications.
As part of our battery development consulting, we focus not only on constructive integration but also on meeting relevant standards and certification requirements—such as UN38.3, IEC 62133, or UL 2054. This ensures cost-effective, assembly-friendly, and certifiable solutions—precisely tailored to your application.
Charging technology—safe, efficient, and optimized for your application
A high-performance battery reaches its full potential only with the right charging technology. Together with you, we develop charging strategies precisely tailored to your cell chemistry, operating environment, and load profiles—from traditional grid power to mobile fast-charging units. We advise on system integration, assist with standards selection, and ensure that charge cycles, efficiency, and lifespan are optimally aligned and work in harmony.
Whether battery concepts with fast charging, intelligent CAN-based charging, or charging solutions for vri BASE LINE—we offer manufacturer-independent battery consulting focused on safety, functionality, and certification readiness.


BMS – Batterie management system


The battery management system (BMS) is the core of every intelligent and long-lasting battery solution. It protects cells from overload, controls charging and discharging processes, and provides precise data for system monitoring to ensure optimal performance. Together with you, we develop a BMS concept perfectly tailored to your system.
Focusing on lifespan, safety, and regulatory compliance, we support you in selecting, configuring, and implementing the BMS. This way, we design battery concepts that are not only technically robust but also economically viable in the long term. Whether it’s a custom solution or a standardized battery concept like vri BASE LINE, we always consider the entire system—from the cell to the certified battery system.
