Exploring Battery Simulator

Battery Simulator-Chroma A170202

Battery Simulator

Chroma A170202

Validate device functions during development in lieu of an actual battery or batteries.

Testing battery connected devices with an actual battery can either be cost or time prohibitive especially if multiple channels are required. Our Battery Simulation software is used to validate device functions during development in lieu of an actual battery or batteries. Automotive applications include motor drivers, OBC, DC-DC convertors or chargers, and products of DC bus.

  • Multichannel battery packs state simulation.
  • Follow the battery cell curve behavior to simulate battery state.
  • Able to set frequently used parameters for battery pack and rapidly customize initial output state.
  • Regenerative battery energy discharge function, power saving, environment-friendly and low heat output with 85% efficiency.
  • Up to 60 channels can be paralleled for large current request.
  • Operating mode: Constant Current/Constant Voltage/Constant Power discharge - 600W, 1.25kW, 2.5kW, 5kW,10kW, 20kW, 30kW, 50kW, 60kW power per channel - 20V, 60V, 100V, 200V and 500V voltage modules - 2600A maximum current (paralleled)
  • Dynamic current charge and discharge simulation.
  • Highly accurate current and voltage measurement.
  • Smooth and rapid current charge and discharge switching without interruption.
  • Current smooth without surge when altering charge and discharge mode (CC-CV-CP).
  • Independent channel protection function.

How to select the battery simulator or DC power supply and DC load integrated solution?

The integrated solution of DC power supply and DC load can also form a battery simulator; however, the difference between it and the bidirectional power supply is if there is delay during conversion. It is suggested to use the 17020 to test the bidirectional products, and use the 17020 or DC power supply and DC load integrated solution for testing the unidirectional products.
