Electric Powertrain Testing

Data Acquisition Solutions for Electric Vehicle Testing

For hybrid electric (HEV) and all-electric vehicle (EV), a high-voltage bus supplied by a large battery pack drives the electric powertrain. Most of the components are bidirectional, allowing power to go from the battery to the inverter, which turns the motor moving the vehicle or driving power back through the inverter and charging the battery when braking. Each step of this powertrain requires thorough testing to maximize energy efficiency for the HEV/EV. 

Gantner Instruments’ bestselling data acquisition product line, the Q.series X, has been extended to include a variety of high-voltage isolation measurement modules that combine precise and stable signal conditioning with safe electrical isolation up to 5000 VDC peak and 1200 VDC continuously. The range of modules supports various measurement inputs for voltage, current, RTD, thermocouple, IEPE, and strain gage sensors with data sampling up to 100 kHz.

Connectivity

With the functionality of GI.connectivity, the high-voltage isolation modules are a unique solution for test system integrators. Add a Q.station X controller for intelligent data switching to various Fieldbus or Ethernet protocols, or add an EtherCAT bus coupler for flawless integration with test automation systems like PAtools TX (KRATZER AUTOMATION), MORPHEE (FEV), or PUMA 2 (AVL).

In combination with the GI.bench software, the Q.series X measurement modules turn into a data acquisition solution for test lab end users. GI.bench enables a quick and easy setup of multi-channel DAQ systems, multi-frequency data logging, and engaging dashboards for data monitoring and analyses.

The channel granularity of Q.series X, combined with the flexibility to mix and distribute low-voltage and high-voltage isolation modules, provides customers assurance that they have a powerful, flexible, and industry-leading data acquisition system to overcome challenges in electric vehicle optimization.

Gantner Instruments is dedicated to helping our customers transition smoothly from combustion engine technology to electric vehicles, supporting a sustainable mobility future.

Testing solutions for all development and qualification steps: 

These tests are executed with the Gantner solution:

  • Charge/discharge cycle testing – Determine the number of times a battery can be used by evaluating it until it deteriorates after repeated charging and discharging charges.
  • Battery Model development(SoC, SoH determination and prediction, constant discharge testing, Charge/Discharge rate and efficiency)
  • Safety (abuse) testing – Simulate a wide range of environmental conditions and battery failure scenarios to determine the conditions for battery failure.
  • Performance testing – Demonstrate the efficiency of batteries. Our experts can customize testing programs to suit specific customer requirements, such as performance testing under various climatic conditions.
  • Environmental and thermal testing – Demonstrate the quality and reliability of your battery. Our tests include vibration, shock, EMC, thermal cycling, corrosion, dust, salt, and humidity.
  • Transport testing – Ensure your batteries can be transported safely. We conduct tests for the United Nations requirements (UN 38.3) for the safe transportation of batteries, modules, and cells.
