INTRODUCTION
THE ENGINEERING PULSE OF AFRICA
Promote the use of alternative energy resources
Involve schools to create interest and to up the
standards in the science and technology department
Improve CPUT’s collaboration with The Hague
Hogeschool
Study of latest composite materials
THE ENGINEERING PULSE OF AFRICA
VISION
MISSION
When
How
Why
What Where
Hydrogen powered vehicle
To win a world class event
Using state of the art technology
Prototype finished by October 2011 and participating in May 2012
CPUT (South Africa)
MISSION
THE ENGINEERING PULSE OF AFRICA
THE ENGINEERING PULSE OF AFRICA
Setting new benchmarks for Africa
Exchanging knowledge
Different approaches to problem solving
Building new relationships
Experience different cultures
Synchronising schedules between the two
faculties, CPUT and The Hague
INTERNATIONALIZATION
ELECTRICAL
THE ENGINEERING PULSE OF AFRICA
Motor Drive:

ELECTRICAL
THE ENGINEERING PULSE OF AFRICA
Controller:
PRO’s 3 phase No transmission required
CON’s Does not meet all
specifications
PRO’s 3 Phase Meets all specifications
CON’s Transmission required
Therefore the Brushless DC Motor was chosen
Hub Motors Brushless DC Motors
Motor Specifications: Torque, Voltage, Current, Power

Fuel Cell:
- No complex humidification
- No heavy air compressor
- Wide power range
- No liquid cooling of the stack
- Quick and easy to replace a
single damaged cells
- 5kg
THE ENGINEERING PULSE OF AFRICA
MES 1.0
Capacitors:
- Depending on demand of motor
(Torque)
- Depending on backup system
- Maxwell 350F - 2.7V
- 10 year life span
- Lightweight construction (63g each)
- Higher energy capacity then batteries

Fuel Control topology:
Semi Monocoque:
- Internal ribs for strengthening
- Maximizes strength to weight ratio
- Allows integration of sub-componets
Drive train:
- Reduction box
- Solid drive shaft
