WF Bifrost Module Tester Series

The WF Bifrost Module Tester Series from WireFlow is a battery module tester where each channel can be run simultaneously and independent from each other.

The available products have been designed and built according to the real customer needs. Compared to other available products in the market, our module series provides you with all you need to shift seamlessly from simple to advanced test and measurements with the possibility of a high degree of customization


  • Design verification
  • Dynamic cycling
  • Fast charge-/discharge test
  • Delivery and maintenance charging
  • SOH measurement
  • WireFlow Total Discharge TM


  • Research and development
  • Manufacturing
  • After market and refurbishment
  • Remanufacturing
  • Repurposing
  • Recycling



In these product series, we offer off-the-shelf products as well as customised systems with different functionalities to deliver a solution meeting your specific needs.


The system has a built-in script engine where you can write your own test sequences. All variables are available in the scripting environment, so it is easy to set up tests with almost any criterion. Tests can range from simple test cases such as cycling whilst doing coulomb counting to more advanced test cases.

Accessible historical data

All data that is available within the system can be logged during a test. The log files are easily accessible and exported to adjacent systems for further analysis


The system is controlled by a user-friendly software as a single point of contact. All channels can be run simultaneously and independent from each other and are controlled and monitored from one application.

Able to integrate

Using our Rest API, you can communicate and control the system from any adjacent system making it a seamless part of your production and test infrastructure.

Sustainable/lower cost of ownership

The system is regenerative where the power from discharge is fed back to the grid, minimizing heat dissipation as well as lowering the operating cost.


The system has support for monitoring temperatures, both internal and external, used for safety and to evaluate how the battery responds to different charge and discharge currents. All channels can be run simultaneously and independent from each other.


All products in this series are based on the Valand Battery Test and Measurement platform meaning that it makes it possible for customers to upgrade the systems with new versions and customer specific functionalities if needed.
