A 34972A data acquisition unit from Keysight (with built-in thermocouple junction reference) is likewise being utilised in this project, for vehicle diagnostic purposes. This incorporates a pair of 20-channel 34901A multiplexing modules plus the multi-faceted BenchVue software package. Via the unit, data from a series of thermocouple-based sensors, located at different points throughout the battery pack, can be captured for subsequent analysis, so as to ensure that operational effectiveness of the vehicle’s battery/powertrain is maintained.
For the next stages of the project’s development Microlease will be providing a Keysight N6705B DC power analyser, along with associated software. This will enable comprehensive studying of the DC loads that the vehicle has to deal with during races, so that full optimisation of the battery resource can be achieved. The team are currently completing sub-system testing. They will be starting on system level testing and rolling road tests this spring, ahead of race day which takes place in July.
“This event is a unique opportunity for university undergraduates to gain real hands-on experience of taking an engineering project all the way from the drawing board right through to completion,” states Glenn Howard, Field Sales Engineer at Microlease. “By collaborating with TBRe on their Formula Student electric car, we are helping to nurture the next generation of engineers.”
“Microlease’s contribution has proved to be invaluable to the team over the last 8 months,” explains Seán Thompson, a senior member of TBRe. “As well as the kit they have given us access to, there is also the ongoing technical advice that has been provided. With their help, we have been able to make improvements to our design that have resulted in a clear competitive edge being derived.”
