solar array
Solar Array
  • 6m2 SunPower B30 monocrystalline silicon cells
  • Split into 4 sub-arrays
  • Specialist encapsulation, increasing efficiency by ~4%
  • 22% efficient overall
  • 1.3kW measured max power output
  • Value: £22,500
maximum powerpoint trackers
Maximum PowerPoint Trackers
  • Also known as MPPTs
  • Built to custom specification by Drivetek
  • Essentially a DC/DC converter, converting array voltage to HV bus voltage
  • 98% efficient
  • 4 MPPTs, one to interface with each of the sub-arrays of solar cells
motor motor controller
Motor & Motor Controller
  • 1.8kW CSIRO 3-phase brushless DC hub motor
  • 98% efficient
  • 4kW peak power
  • Custom designed hub, machined by Cambridge Precision
  • Value: £18,000
  • Motor Controller: Tritium Wavesculptor
  • Value: £5,500
battery
Battery
  • LiFePO4 chemistry
  • Limited by World Solar Challenge regulations to 40kgs
  • Capacity of over 4kWhr
  • 125V nominal
  • Custom BMS with CAN interface module
control and data acquisition
Control and Data Acquisition
  • Entire solution provided by National Instruments CompactRIO
  • Interfaces with CAN busses
  • Driver inputs and vehicle instrumentation connected directly to modules
  • Telemetry radio connected to serial output port
control and data acquisition1
Control and Data Acquisition
  • High-speed control loop run in FPGA, providing fast, reliable response to driver inputs
  • Background loop run in Real-Time Controller
    • Sets maximum allowable currents
    • Determines preferred speed for cruise control
    • Logs all data
    • Selects data to be transmitted over telemetry, to minimise power consumption
