Our Experience…

23-04-10 4

• Advance DC Machines

• Development of DC controllers

• Battery conditioning tests

• Battery technology scans

• Life cycle testing

• Analysis of failures and costs

So what has changed to date

High Costs of Infrastructure

Actual habit of PEV vehicles : Where would we charge?

Localization of Market

Multiple customers in the same area

•Upgrade of Lines transformers

•Substations

•Potentially new generation and transmission capacity

Present Loading 7.5 x 40 = 300 KVA

Assume 5 KW = Additional Load 200KVA – Max load now 500KVA

Impact on Peak Loads

• Different charging options

• Unmanaged Charging

• Controlled charging

• Time of Use charging

• Smart Charging

Business Models

• Utility owns EV charging equipment

• Subsidy from Utility

• Consumers ownership

Why do we need to do this research

• PEV potentially will have an impact in all aspects of Eskom business

• Regulation and policy within Eskom need to understand the legislation impacts

• New tools required by engineers and planners on forecasting

• Tools and process may need to be aligned to better manage the distribution network.

• Impact to the IDM from a demand management perspective.

• Smart grid implications on network architecture

• New real time customer information and billing systems

• Network support skills for new electrical infrastructure

• Potential of using EV as Eskom Fleet
