CSIR Energy-Autonomous Campus in Pretoria: Real-world implementation of a least-cost, renewables-based microgrid
4
What is different today as compared to just a few years ago?
Battery prices have been decreasing globally• Electric vehicles starting to be cost competitive to conventionals• Economies of scale (there has been talks of mass production by some companies)
Technology advances• Longer range• Look and feel of a “normal” car
New Regulations aimed at promoting EVs • Governments setting aggressive targets (production quotas) • Car manufactures committing to increasing investments in EV production • Introduction of carbon emission tax
5
Why EVs at the CSIR
• EVs are environmentally friendly• No tail pipe air pollutants at the place where they are operated. • They generate less noise pollution than an internal combustion vehicle, whether at rest or in
motion.• The energy that electric cars consume is usually generated by means that have environmental
impacts.
• Demand Side Management (V2G)• EVs can be plugged into the electric grid when not in use e.g. during peak use periods • Charging at night, when there is unused generating capacity.• Potential to reduce the need for new power plants.
• Complement/supplement variable loads such Wind and Solar PV• Current electricity infrastructure will need to cope with increasing shares of variable-output power
sources such as windmills and PV solar panels. • Variability could be addressed by adjusting the speed at which EV batteries are charged and
discharged.

Why EVs at the CSIR
• CSIR energy autonomous campus objective• Demand side management• Zero pollution • Contribution towards enhancing the adoption of EVs in South Africa and possibly the continent via
directed research

The BMW i3 and the Nissan Leaf at the CSIR
BMW i3: • Battery range – 129 km• Electric range, everyday use – upto 150 km• Quick charge time – 30 Mins• Energy consumption – 13.5 kWh/100 km• Top speed – 150 km/h
Nissan Leaf: • Battery range – 135 km• Electric range, everyday use – 135 km• Quick charge time – 30 Mins• Energy consumption – 18.6 kWh/100 km• Top speed – 144 km/h
8
Current activities
Integration into the CSIR Fleet• Fully integrated, • Available to any CSIR employee
Promoting the EVs at Conferences and Fairs• CSIR Conference• Science Forum South Africa (SFSA)
Research: • Developing the research agenda• Exploring potential partnerships with relevant stakeholders
9
Current activities
• Monthly reports for vehicle utilization are compiled.
• Data collection done using the telematic systems and manually.
• Discrepancies between manual data and that obtained from telematics system.
• Telematic system installed in the Nissan Leafs and BMW has, in principle, allowed CSIR to install the telematic systems.
• The electric vehicles are not being used enough to generate sufficient data for the planned studies

Challenges
• Low uptake and utilization (especially with the Nissan Leafs)• BMWs popular as they have a range extender• Nissan Leaf has no range extender
• Data on the performance of the BMWi3s is not available • BMW has agreed that data loggers can now be installed in the vehicles.• This will enhance EV utilisation research
12
Future work
EV roadshow/workshop for the CSIR employees• Create awareness around the CSIR• EVs available for use by all CSIR employees• Clarify any existing misconceptions about electric vehicles
Additional charging stations • Installation of fast charging stations• Encourage other stakeholders e.g. City of Tshwane to increase charging stations
Data collection process• Collaborate with stakeholders improve data collection process e.g. make use of apps
Accelerate EV research projects
