Methods & Expertise for Research Infrastructure
An in-house developed open software platform is used for data acquisition and control of the power supply equipment and drivetrain test facilities. The software allows centralized and time-synchronous acquisition, storage and visualization of measurement data. The integrated control option enables the simulation of user-defined performance profiles or drive cycles and the definition of semi- or fully automatic test procedures for the measurement of efficiency maps. The following interfaces are available for the integration of customers’ drive control systems:
• Analog input/output
• Digital input/output
• CAN interface
