The GMS Kart represents a unique opportunity to involve teams of students in a cost effective project, which is both exhilarating and educational. Karting is globally known as the grassroots start of professional motor sport.
When asked about electric vehicles, most people think of milk floats or forklift trucks; However, the fact is, that enormous power is available from electric motors.
The GMS electric kart ably demonstrates this and forces a re-appraisal of this misconception, as it cannot be described as slow!
For safety, the kart is built on a professionally made chassis, power profiles are set and governed by Green MotorSport suitable for educational projects. The electronic motor controller is programmable and it acts as a data-logger. Tutors can therefore use the data to demonstrate electrical principles regarding motor control and the losses involved. The team can also use the data to monitor the karts racing performance.
The maximum speed and acceleration of the kart can be altered in the Green MotorSport controller using a laptop. It can therefore be set to lower values for use by younger or less experienced students, so the same kart can be used for several groups or drivers with differing abilities.
Students will be introduced to a new way of thinking about electric vehicles. Karting will capture their imagination and create an atmosphere in which they will immediately learn about the benefits of the green technology. Students will see how the motors and batteries work, as well as understanding the benefits of combining these technologies with renewable energies and new storage systems.
Understanding the reasons why we need to reduce our carbon footprint, the effects of carbon dioxide on our climate, and using energy efficiently, are serious milestones. We must understand how these systems play a part towards moving away from fossil fuels towards an efficient low carbon future.
Datalogging
The datalogger records Battery Volts, Battery Current, Motor Volts, Motor Current, Battery Capacity used, Motor Speed, Controller Temperature, Throttle Position. This data can be viewed in the Green MotorSport software supplied and viewed numerically or graphically. The figures will allow the students to calculate losses, and see the effects of changing settings (either in the control system, or the chassis). They can also analyse where they are wasting power around a race circuit in order to maximise performance. |
