Electric vehicles are fast gaining traction globally as there is a drive to reduce toxic vehicle emissions in cities whilst simultaneously reducing many nations exposure to the international oil market. Key legislation in the EU, USA, China and potentially Australia could lead to a rapid increase in the number of electric vehicles on the road.

 

Charging of electric vehicles is currently not considered a significant issue for the high voltage electrical distribution network in the short to medium term as the power requirements for charging an electric vehicle are low compared to other industrial processes and because most EV’s are typically charged at night when demand is low. However, there are significant barriers to installation of fast (L3) and slow (L2) charging in areas that are not traditionally well connected to the electrical grid such as refuelling stations, multi-story car parks and households with multiple vehicles. Upgrading electrical connections to these locations is feasible but can be high cost. In addition, a charging station may not be used frequently or only for short durations leading to the expensive installation not being fully utilised.

 

Solar and storage offers a potential solution that can both reduce the cost of installation of charging equipment and can provide surplus electricity to a site when not required for car charging. These and other benefits can lead to the integrated system being more attractive than individual non-integrated systems or for lone installations of one technology. In addition to permanent charging stations there is also a need to develop temporary portable solutions to allow rapid deployment for field trials, temporary replacement of inactive charging stations and for supplementing networks during periods of high demand. Delta Energy systems and CSIRO have been collaborating in the development of a number of charging solutions for fleet vehicles, mobile, off grid and grid constrained locations.

 

This presentation will offer an overview of the area and greater detail of the prototypes currently being developed and trialled at CSIRO.

 

3 key takeaways from this presentation:

1. An understanding of the uniquely Australian challenges and opportunities that electric vehicle charging provides

2. The benefits of combining solar, battery storage and electric vehicle charging

3. The potential market growth in Australia and what it means for local industry.
