For the powertrain team October was filled with a large variety of activities. Of course, the major part of these activities were engineering related, but we also visited a few events with the team: The Military in Boekelo, and Electrified in Rotterdam. Furthermore, serveral company visits were made to re-establish fruitful partnerships of previous years and to make new partners.
One of the engineering projects we have been working on this month was the redesigning of the wiring harness. In the current design, there are some points that can be improved to for example improve the functioning of the data communication lines that run through the bike. Furthermore, some tidying up could be done by reducing the length of some excessively long cables and using the frame as a path to the low voltage ground. Since the rewiring of the bike will require the use of certain specific cables, we are really happy that Helukabel is willing to sponsor the team for the 3rd year in a row!
Another project this month was to install the cooling node in the bike. The function of the cooling node is to regulate the power going to the pumps in the oil and cooling loops of the bike. In addition, the temperature and flow rate sensors of the cooling loops, as well as the temperature sensors in the electromotor are connected to this node. To test whether everything is functioning as expected, the bike will be tested on the dynamometer next week. The process of testing on the dynamometer requires quite a lot of preparation and precautions, and therefore Steven – chief powertrain of EST 4 – was so kind to run through the process with us, so that we can test next week.
