EV SmartCharge Queensland Program Insights
Insight 1: Program overview and early insights
Learn more about the research program and the participants and how, by better understanding EV charging, we can:
- Enhance our education to customers about the best charging methods
- Prepare to influence and manage EV charging in mutually beneficial ways.
Fourteen different EV models are represented in the program, 76% of the participants had a solar system and 18% had a stationary battery.
Read more about the type of chargers and charging behaviour in our Program Overview and Early Insights (PDF 701.8 kb).
Insight 2: Weekday and weekend charging
This insight explores:
- Are electricity tariffs influencing EV charging behaviour?
- The number of vehicles charging during a weekday compared to the weekend is generally consistent, but when do owners charge their EVs most often and least often?
- Does having solar panels, compared with having both solar and battery, impact an EV owners' charging habits?
Learn more in our Weekday and Weekend Energy Consumption Profiles (PDF 683.5 kb).
Insight 3: Battery state of charge and state of health
In this insight you can:
- Learn if there are strategies to extend an EV battery’s life ('whole of life')
- See if EV battery degradation is occurring faster than you think
- Check out how different vehicle types exhibit different State of Charge at both commencement and end of charging sessions and identify why BEV and PHEV owners' charging is different.

Insight 4: Home versus away from home charging
In this insight:
- See if the amount of 'home' versus 'away from home' charging is as you expected
- Discover if the charging behaviour is the same for residential vehicles compared to commercial vehicles
- Is charging at home similar or not, depending on whether you have just solar, or solar with battery storage?
Read more about this charging behaviour in Home versus Away from Home EV Charging (PDF 391.4 kb).
Insight 5: Diversified charging profiles
In this insight:
- Explore diversified load profiles and the impact EV charging may have at different levels of the electricity network.
Learn more about this charging behaviour in Diversified Charging Profiles (PDF 401.2 kb).
Customer experience journey mapping research
We completed research jointly with Ergon Energy Network to understand the customer experience from consideration of buying an EV, through to how customers use and manage their EVs, with a focus on how they charge their EVs.
- Price was the barrier to purchasing an EV
- Charging EVs became part of a total home energy management routine for those who have a home battery and solar
- The preference was to avoid using the grid and leverage solar power charge EVs (and home batteries)
- A common charging behaviour was to ‘top-up’ the EV battery to meet travel requirements for the next day, with an allowance of additional kilometres as a ‘safety buffer’.

At the end of May 2022, Queensland had registrations for:
- 8,924 BEVs, including 37 electric buses,
- 2,499 PHEVs, and
- 1,009 electric motorcycles,
creating a total of:
- 11,423 EVs excluding motorcycles, and
- 12,432 inc. motorcycles.
Source: Analysis of data of battery EVs and plug-in hybrid EVs, provided monthly to us by the Queensland Department of Transport and Main Roads under a Memorandum of Understanding.
Of all EVs (excluding motorcycles) in Queensland, 90.1% are registered in south-east Queensland, and 9.9% in regional Queensland.

A glimpse into the future of Vehicle-to-Grid (V2G) technology:
- However, only 10% of EVs in Queensland have V2G capability and no new models with V2G capability have been announced for release in Australia in 2022.
Data released by the Australian Bureau of Statistics indicates that in Queensland, passenger Battery EVs travelled 9.9% further than other passenger vehicles in 2019/20:
- Our EV SmartCharge (Queensland) program’s real-world data, when extrapolated to all Queensland passenger BEVs, indicates that in 2020/21, all Queensland passenger BEVs were driven around 13% further than other passenger cars.
