838 - e-Powertrain Test Cell Equipment Supply and Installation

The College of Engineering and Physical Sciences (EPS) at Aston University is seeking to acquire an e-motor test system for durability and functionality testing of electric motors for electric vehicles (EVs) following standard and no-standard test cycles.

This system will form part of their integral research programme looking at Sustainable Energy and Transport. To meet the requirements, the e-motor test system must meet the following criteria:

- Be able to test electric motors for EVs with rated power up to about 175 kW, rated torque 420 N.m, and rated speed 16,0000 rpm, with inertia equal or lower than 0.3 kg.m2.

- Have the AC dynamometer mounted on a metal base plate for which air springs must be supplied to be adapted to the existing one or a full metal base plate with air springs provided.

- Include Turnkey control and data acquisition system conveniently integrated in table/rack/cabinet structure with dynamometer controller, computer, monitor, emergency stop button, power analyser and weather station plus user-friendly software able to reproduce standard/custom test schedules.

- Include dynamometer shaft cover for operator safety.

- Include calibration arms and weights.

- Include a battery emulator to simulate operation of various EV battery types.

- Include specimen adaptation and conditioning unit.

The full project specific requirements and equipment specification can be found within the project question set on Aston University's e-tendering portal ProContract under Section 11 - Project Specific Requirements.
