Test solutions for electromobility

Quality assurance for battery cells and high-voltage components

Precise testing technoloy for electromobility

Reliable test systems for the quality assurance of battery cells and high-current components - from cell testing to fast charging processes.
Our core competencies in the field of e-mobility:

  • Battery cell testing: Test systems for measuring cell capacity, internal resistance and leakage currents - adapted to the cell format, cycle time and degree of automation.
  • High-current tests under real conditions: Simulation of charging and discharging processes with high currents (up to several hundred amps) and voltages up to 800 V - including temperature monitoring and active cooling if required.
  • Insulation tests: Verification of the electrical safety of high-voltage components - standard-compliant, reproducible and process-safe.
  • Modular adapter solutions: Flexibly configurable for different cell formats, module sizes and contacting requirements - with a focus on longevity and easy maintenance.

Testing requirements in the high-voltage range

Challenges in battery technology

Due to the simultaneous occurrence of high voltages and currents, electromobility places high demands on the components installed:

  • High charging and discharging currents at high voltage: fast charging processes with several hundred amperes and voltages of 400 V to 800 V require special testing processes to ensure safety and stability.
  • Thermal management: High currents generate high temperatures. Without active cooling, this can lead to material damage, incorrect measurement results or hazards.
  • Ageing processes and degradation: Repeated fast charging cycles affect the cell chemistry. Reliable statements on service life can only be made through long-term tests under real conditions.
  • Mechanical and electrical interface diversity: Different cell formats and contacting require flexible adapter solutions - with short set-up times and high repeat accuracy.

From the requirement to the individual test solution

Your Project with wemonte

Clear process, no surprises: We work according to a structured process - from the first meeting to the finished test solution. Technical requirements, costs and time frames are coordinated transparently. The basis: a reliable specification sheet and a binding offer.

All services from a single source - with a personal contact person.

1. Technical requirements & project start :

We clarify all test-relevant parameters with you: Cell type, current/voltage ranges, temperature behavior, interfaces and cycle time. On this basis, you will receive a transparently calculated offer - binding and tailored to your application.

2. Concept development & technical design :

Based on your specifications, we develop a customized solution: modular, low-maintenance and scalable - tailored to your testing strategy and production environment.

3. Adapter design & production:

Once the design has been approved, we start with material procurement and assembly planning. We usually deliver adapters from the Basic series within 6 weeks of design approval. Complex projects with specific contacting or cooling are manufactured individually.

4. Quality assurance & delivery:

Each test system is tested at our site in Stuttgart before dispatch. You will receive complete documentation including operating instructions, test protocols and circuit diagrams.

5. Long-term support & retrofitting capability:

We remain your partner even after commissioning - for maintenance, extensions or adaptations in the event of changed test requirements. All services from a single source, with a personal contact person.

Frequently asked questions about battery testing

FAQs

The project duration depends on the scope and complexity. We usually deliver standardized adapter solutions (Link: Basic) within 6 weeks of design approval, while individual systems (Link: Sophisticated or Link: Unique) are planned individually. Delivery times depend on the availability of the components.

Yes. Our adapters can be subjected to a high-current test if required. Depending on the requirements, the test is carried out either in our own high-current test bench or in cooperation with an established test laboratory.

Yes. We develop our systems with compatibility in mind. We adapt interfaces and mechanical integration to your circumstances.

Our adapters and test solutions are developed and tested at our headquarters in Stuttgart. We work with regional partners for assembly. This guarantees short distances, high quality and full transparency at every stage of the project.

Yes, we also support you after delivery with maintenance offers, retrofits and technical support - long-term and reliable.

High-current tests generate high thermal loads. Our adapter solutions can be equipped with active cooling - e.g. air or liquid cooling - to maintain temperature limits and reliably protect cells and test technology.

The costs vary depending on the test task, complexity and adapter type. After the joint requirements analysis, you will receive a binding offer - transparent and comprehensible.
