Automated testing for short cycle times and reproducible quality
Customized end-of-line and ATE test systems for electrical assemblies, power supplies, converters, BMS, batteries and power electronics – with programmable sources, loads, simulation, measurement, safe contacting and automated result evaluation.
From scanning to automatic release
Electrical functional testing, load testing and documentation in one coordinated process
In production, devices under test must be evaluated quickly, safely and under identical conditions. To achieve this, we combine programmable power supplies, electronic loads, bidirectional sources, battery cell simulators, measurement modules, contacting and control into a tailored complete solution.
More than just a single instrument
A high-performance EOL test station is created through the interaction of power supply, loading, signal and fault simulation, measurement, safety, software and mechanical integration. The components are selected to match the device under test and the intended production process.
Designed for stable processes
Automated sequences, defined ramps, dynamic profiles, digital triggers and clear limits deliver reproducible results. This enables early fault detection, targeted analysis of rejects and full traceability of production data throughout the entire product life cycle.
From the device under test to the documented result
The exact process is tailored to the product, quality requirements, cycle time and existing production environment.
Flexible EOL testing for different products and power classes
The test architecture can be designed for applications ranging from a few watts and multiple parallel channels to high-voltage and high-power testing.
Power supplies, chargers and power supply units
Testing of output characteristics, control behavior, efficiency, ripple, protection functions and communication interfaces.
DC/DC converters and power modules
Automated power supply on the input side and programmable loading on the output side with dynamic profiles.
OBCs, inverters and HV components
Testing of high-voltage components with safe enable sequences, precharge, source/sink operation and project-specific protective equipment.
BMS, CMU and electronic control units
Simulation of cell voltages, temperatures, current signals and fault conditions for reproducible functional and communication tests.
Battery modules and energy storage systems
Controlled charging and discharging, capacity testing, voltage and current monitoring, and safe shutdown sequences.
Electrical assemblies and subsystems
Multi-channel power supply, load simulation, digital and analog signals, and sequence testing for complete assemblies.
No rigid standard test station – the solution is designed around your production process
Product variants, electrical data, cycle time, contacting, the safety concept and existing IT infrastructure determine the system design. Send us your requirements and existing test plans. We assess the technical feasibility, clarify any open points and develop a suitable test and system concept.

Technical clarification before system design
You do not need to have every detail defined in advance. Together, we structure the requirements and assess what can be implemented in a technically sound manner.
Which assembly needs to be tested – and what cycle time do you need to achieve?
Send us the key technical data, the desired test sequence and any available documentation. We assess the requirements and develop the appropriate instrument and system configuration.
