Trials in Australia of the Team’s entry for the Bridgestone World Solar Challenge included using a Tinytag data logger to provide valuable performance data with regard to temperature fluctuations, to help optimise the vehicle design.
Solar Team Great Britain is building a
solar-powered car to compete in the Bridgestone World Solar
Challenge in October 2017. Racing across Australia from
Darwin to Adelaide, a distance of just over 3000km, the Team hopes
to demonstrate the very best of British engineering and innovation.
Throughout this process, the Team wishes to inspire students and
young professionals to apply their talents to sustainability.
The car has been entered into the Cruiser Class; this focusses
on making further progress in the development of a road-legal
family sized solar powered car which can carry upto four
passengers. The end goal is to reach the end of the course with the
most passengers but with the lowest amount of initial energy. The
Challenge takes place over five days, with a defined 3 hour window
for the final time of arrival.
The Tinytag Plus 2 data logger
with two thermistor probes was among a large amount of
measuring and monitoring equipment used on the trial, which will
help the Team to prepare a computer model to optimise the
car's design. The Tinytag data was particularly important
as the silicone solar panels used are temperature sensitive - if
they get too hot for example, they stop performing as
The recorded data illustrated how the temperature varied
at different speeds, and with different amounts of
insulation. The temperature curve showed how the
performance of the insulation is extremely dependent on the speed
of the car. In addition, the data has been passed to the Team's
battery supplier to illustrate the worst case temperature scenarios
that can be expected, so this can be taken into consideration for
design and manufacture.
