Test Systems
We provide customized testing solutions for embedded system development from first prototype to production
Hardware-in-the-Loop
The PTS HiL System is our solution to provide sophisticated test capabilities for battery electronics such as a complete Battery Management System. It makes it possible to safely carry out all critical and safety relevant tests like short circuits, overheating, critical discharge, overcharge in extreme conditions. It also can be used for EV simulation tests to validate your application algorithms in simulated driving or other operation cycles.
With its open interfaces it can be either controlled manually, automated or even be fully integrated in your continuous integration pipeline. Therefore, it can be used in multiple applications during the whole development process. This brings significant gains for quality and speed in Software Development, Validation or End-Of-Line testing.

Functional Test System
We offer customized functional test systems (FCT) for End-of-Line (EOL) testing. The FCT is a comprehensive testing setup used to evaluate the functionality and performance of a product or system before it is shipped or deployed. EOL testing typically occurs at the final stage of the manufacturing process or assembly line. The FCT includes various components and processes designed to verify that the product meets the required specifications and performs as expected.
The individual FCT design combines the following key elements:
Test Fixtures: These are physical or electronic setups that hold the product being tested and provide the necessary connections to interface with it. Test fixtures are designed to simulate the operational environment of the product and ensure proper electrical and mechanical connections for testing.
Test Instruments: These are measurement and testing devices used to capture and analyze the product's performance. Examples include multimeters, oscilloscopes, power supplies, spectrum analyzers, data loggers, and specialized test equipment specific to the product being tested.
Emulation Instruments: Comprises all additional instrumentations necessary to test the product. Examples include cell emulators, shunt and temperature emulators or fault injection boxes.
Test Software: The PTS testing framework runs on an industrial PC and controls the testing process and interacts with the product under test and the test instruments. It provides test sequencing, data collection, and analysis capabilities.
Test Cases: These are step-by-step instructions that define how the product should be tested. Test cases outline the required test setups, measurement points, and expected test results. They are typically created based on product specifications and design requirements.
Test Data Management: This involves storing, organizing, and analyzing the test data collected during EOL testing and sharing it with the EMS via defined interfaces or combining it with a labeling system.
EV Simulator
With PTS, you can expedite the development of your e-mobility applications across various components, including the battery, Battery Management System (BMS), inverter, as well as the charging interfaces of Electric Vehicle (EV) and Electric Vehicle Supply Equipment (EVSE).
Hardware Engineering Tester
A Hardware Engineering Tester (HET) is a specialized testing system used primarily during the development phase of hardware products. It is designed to verify and validate the functionality, performance, and reliability of hardware prototypes or early production units. HETs play a crucial role in identifying and resolving design flaws, ensuring the product meets specifications, and minimizing issues before moving into full-scale production.
Key Elements of a Hardware Engineering Tester (HET):
Test Fixtures: HETs utilize custom-designed test fixtures to securely hold and connect the hardware being tested. These fixtures are specifically tailored to the product's form factor, connectors, and interfaces, allowing for accurate measurements and control during testing.
Test Instruments: HETs incorporate a wide range of test instruments, such as oscilloscopes, logic analyzers, multimeters, spectrum analyzers, and power supplies. These instruments are used to capture, analyze, and validate electrical signals, perform functional tests, and measure performance parameters of the hardware under test.
Stimulus Generation: HETs generate various types of stimuli to simulate real-world operating conditions and stress the hardware. This can include generating specific voltage levels, digital signals, frequency patterns, or environmental stimuli like temperature and humidity variations.
Test Software: The PTS testing framework runs on an industrial PC and enables the control, automation, and data acquisition during testing. The software defines test sequences, executes test cases, captures measurement data, and performs analysis. It provides an interface for configuring tests, displaying results, and generating reports.
Debugging and Troubleshooting Tools: HETs often incorporate features for debugging and troubleshooting hardware issues. This may include built-in circuit access points, probe points, or debugging interfaces to connect external tools for in-depth analysis and debugging of the hardware.
Design Verification and Validation: HETs facilitate design verification and validation by executing a comprehensive set of tests to ensure the hardware meets functional, performance, and reliability requirements. This involves functional testing, signal integrity analysis, power consumption measurements, environmental testing, and other relevant tests.
By utilizing a Hardware Engineering Tester (HET), hardware engineers can efficiently diagnose and rectify design issues, evaluate the performance of early prototypes, and validate the hardware's functionality before mass production. The HET enables thorough testing, reduces development iterations, and improves the overall quality and reliability of the hardware product.
