Electric driveline research status in Uppsala University

Juan de Santiago

Division of Electricity, Uppsala University

Recent test driveline improvements

PM motor design

Next generation flywheel

Superconductive magnetic bearings

The test setup is under constant development. The latest improvements since our last meeting includes

Battery Management System (BMS):

Self developed for battery charging and system protection.

Battery pack:

The battery pack was the last component missing for complete hardware in the loop testing. Previously, the driveline was connected to the grid through a rectifier.

Carbon fiber shell:

We designed a shell to increase the moment of inertia of the reluctance flywheel.

We have a common project together with Federal

University of Rio de Janeiro (UFRJ) and Fluminense

Federal University (UFF). We tested superconductive

magnetic bearings.

Our colleges at UFRJ have

designed and constructed a 200 m long MAGnetic LEVitation (Maglev).

It is under operation in the UFRJ campus in Rio de Janeiro.

UU collaborated with the energy requirements and drive cycles simulations.

Magnetic field distribution in the IPM motor for an electric car that we are building and will be tested in Spring 2016.

Electric motor/generator, magnetic bearings and

carbon fiber flywheel integrated in a compact design.
