ReFreeDrive - Deliverable 7.2: Integrated e-Drive test bench testing results

This report D7.2 details the activities carried out in Task 7.2 of ReFreeDrive’s Work Package 7 (WP7), contributing to the overall objective of the WP, which is to test and gather experimental evidence of the powertrains performance following an incremental approach, starting from the testing of the motors and Power Electronics (PE) designed in WP3, WP4 and WP5 and manufactured in WP6, up to the full vehicle integration.

ReFreeDrive's Task 7.2 is focused on the integration of the powertrain and various vehicle systems in a test bench at CIDAUT, in order to characterize and to validate the vehicle functioning conditions in a controlled and measurable environment. To this end, CIDAUT carried out a series of integration tests on powertrain components, such as accelerator pedal and CAN communication, with the support of IFP Energies Nouvelles (IFPEN), PRIVÉ, University of L’Aquila (UAQ) and R13.

The experimental facility used for testing the 75kW powertrains was equipped with: High Voltage (HV) power supply, Low Voltage (LV) power supply, test bench (load motor), water cooling circuit, accelerator pedal, Controller Area Network (CAN) bus and motor control software, and data acquisition systems.
