Test Systems for Electromobility

Our mobility is in a state of disruption – electric motors are increasingly replacing combustion engines.

A logical decision for our future: on the one hand, fossil fuels are not infinitely available, which makes renewable energies necessary; on the other hand, electric mobility is significantly lower in emissions, quieter and also cheaper in the long term.

The Demand for Test Systems for E-Mobility is Increasing

The Automotive Industry is Changing

For the area of e-mobility, NOFFZ Technologies develops customer-specific test system solutions for validation, functional and end-of-line tests.

Our systems are scalable in all test areas. Starting with single tests of control modules up to comprehensive complete solutions of test lines.

Test systems for DC / AC inverters

The heart of an electric vehicle is its powertrain. This includes the components battery, electric motor and inverters or converters. Inverters convert the direct current of the battery into usable alternating current for the electric motor.

NOFFZ Technologies offers complex test solutions for your inverters – both for validation in endurance tests, functional tests and for production in the end-of-line area.

Validation Tester UTP 9065 Run-in/Screening Test System

Our test solution UTP 9065 Run-in/Screening serves for testing battery packs, but also powertrain and control components. It is suitable for validation test environments in which several devices are tested in parallel over long periods of time under varying environmental factors. At the same time, it can be used for development or production test cases.

The Run-in/Screening test system can be used for parallel tests in varying temperature ranges between -40°C and + 85°C. In addition to the connection to a customer database and the iTAC system, variant management enables individual contacting and measurement of the test items. Furthermore, module-specific temperature curves can be stored.

End-of-Line Tester UTP 7042 for Powertrain Components

The UTP 7042 series is a test platform for EOL and FCT covering a wide variety of performance, functional and communication tests.

The UTP 7042 core system can be equipped with variable measurement instruments and power supplies and can be deployed as a complete, scalable and modular test system. It is the ideal system solution to take over DUT control, measurement and supply in case of a corresponding DUT handling cell, no matter if automated or manual setup is intended.

Test Systems for Battery Modules with Battery Management System

The battery provides the necessary power for all components to move the electric vehicle. Here, high-voltage batteries with typical output voltages between 400 V DC and 800 V DC are used. A battery consists of numerous cells interconnected in parallel and series, which together form a so-called stack. This unit is controlled and monitored by a battery management system (BMS): It creates the necessary cell balancing, prevents short circuits and protects against overtemperature.

NOFFZ Technologies offers an innovative test concept that simulates both charge cycles and load cycles.

We use the DC supply to charge the battery and the electronic DC load to simulate the loads on the output side (e.g. electric motor or actuators). The CAN interface, which is used to communicate and control the battery and which also connects the battery and the battery management system, is also tested. Current data such as charge status, input and output current, voltage of individual cells and battery temperature can also be read out and logged from the BMS.

Test Solutions for Charging Systems and Charging Cables

What was previously the refueling of fossil fuel is now the power supply by means of a charging system.

Electric vehicles can be charged with electrical energy via different charging devices, which is then temporarily stored in the batteries and passed on to the engine.
EVSE charging systems (Electric Vehicle Supply Equipment) convert AC voltage from the grid directly into DC current for the battery. EV wall charging stations, known as “wallboxes,” on the other hand, do not convert the AC voltage from the house connection directly into a usable DC voltage. For this intermediate step, an on-board charger (OBC) is used, which is installed in the vehicle and ensures the authentication of the electric vehicle at the charging station.

NOFFZ Switch and Load Boxes

NOFFZ Technologies offers the solution for secure testing of EVSE charging systems and EV wall charging stations (wallboxes) for any test environment.

The focus of our test solution is the communication between EV wall charging station or EVSE charging system. The electric vehicle is connected to the charging station via a charging cable, in which a control box, the ICCB (In-Cable Control Box), is integrated.

With the help of our NOFFZ switch and load boxes, various changing faults and situations can then be simulated to test the response of the charging station and the. In parallel, all electrical quantities required and relevant are measured and logged. In addition, the software of the test system takes over the control of energy sources and sinks.

Software UTP Suite

Our universal test software UTP Suite is the core element of our test systems and is successfully used from product validation to production testing.

The software is based on established test environments such as NI TestStand, NI LabVIEW and .NET.

With the UTP Suite, extensive tester configurations and a higher-level tester administration are possible, which, thanks to a simple modular system, is individually tailored to the respective requirement and the device under test.

It covers extensive tasks such as product variant management, product traceability, data reporting and analysis, abstraction of hardware and measurements and software distribution.
