Drivetrain Inverter Testing

Development and testing of the drivetrain and its components play a central role in the design of hybrid and electric vehicles. REGATRON’s preconfigured drivetrain development and test solutions are

designed to do just that, helping engineers to get results quickly and without the tedious work of changeover.

Key Points

  • Modular and scalable design: REGATRON’s drivetrain testers offer flexible power configurations ranging from 9 kW to over 5000 kW, enabling seamless adaptation to diverse drivetrain testing scenarios and future requirements.
  • Advanced voltage and current flexibility: With autoranging units, the testers efficiently handle applications from 48 V mild hybrid systems to high-voltage solutions up to 3000 V, including electric vehicles, utility vehicles, and specialized electric aircraft.
  • Comprehensive safety and integration features: Equipped with the G5.ISR safety interface, optional DC discharge unit (DDU), optional power distribution units (PDU), and advanced cooling options, these testers ensure reliable operation and smooth integration into motor test benches.

Description

Drivetrain testers are crucial for evaluating the performance and reliability of drivetrain systems, including motors, inverters, and batteries. They simulate real-world conditions, enabling engineers to optimize performance under various scenarios. From mild hybrids to electric vehicles and aircraft, these testers handle diverse applications with modular, scalable designs. They replicate charging and discharging cycles, ensuring safety, efficiency, and compliance with automotive standards. Drivetrain testers are vital tools for advancing electrified transportation.

Typical Application Areas for REGATRON’s Drivetrain Tester Series

  • 48 V mild hybrid systems: The power requirements can be covered in finely graduated 9 kW / 338 A steps.
  • Plug-in hybrid or EV in the range of 400 to 800 V: 1000 V units with an autoranging factor of 3 offer full power over the entire voltage range.
  • Electrification of utility vehicles up to 1500 V: 1000 V units in series operation or 1500 V units in parallel operation cover these requirements easily.
  • For special applications, such as electric aircraft, the modular concept offers even system voltages of 2000 or 3000 V using series or matrix operation mode.

Scope of Delivery Example of a REGATRON G5.DT Test Solution

Drivetrain test solution with REGATRON G5.DT series

In the present example, a prewired reserve space is provided in the cabinet which allows the 216 kW drivetrain tester to be expanded to 270 kW. The integration of the additional 54 kW unit can be done easily at a later stage by the user on site. The power supply may be installed in the equipment room. The DC power can be connected to different motor test benches by means of (automated) DC switches. At the test bench, the DC power is tapped via power distribution units (PDU). The installed resistors of the DDU discharge the residual energy of the rotating element in the event of an emergency stop. One of the advantages is that this saves space in the test cell. The PDUs offer various options such as DC connectors, G5.RCU.FD display with IP54 protection class, emergency stop button including safety door limit switch, selector switch and status indicators.

Why REGATRON Devices for Drivetrain Testing

REGATRON’s G5.DT is the ideal choice for drivetrain testing due to its highly modular and reliable design, allowing for seamless power expansion and quick unit replacement if needed. With an unrivaled voltage-current range and unique dynamics in the 50-100 μs range, our systems deliver the precision and speed required for demanding automotive standards like LV124, LV148, and ISO16750-2. Features like switchable output capacitance ensure stable battery emulation and ultra-fast voltage slopes, while the G5.ISR safety interface enables easy integration into motor test benches. The optional DC discharge unit (DDU) ensures reliable discharge of the rotating energy of the machine when emergency stops are triggered. Space-saving designs, optional liquid cooling, predefined battery models, and power distribution options further enhance flexibility and efficiency.
