- EV sales are exploding world wide
- 10% of Oz vehicle sales in 2023 to date. 200% increase on 2022
- China 35% of vehicle seals EV
- Electrification will reduce the transport sector’s emissions by 80%.
- EV batteries will support the grid providing accessible storage.
- EVs will slash air pollution from gases such NO2, brake particulate.
18% of Australia’s emissions are from transport.
- 52% are from passenger vehicles
- 39% Semis, vans, trucks
How climate-friendly is an electric car?
Where you live can make a big difference to how climate-friendly your car is.
Impact | Tesla
Our mission is to accelerate the world’s transition to sustainable energy. Read our 2022 Impact Report.
Semis are 1% of vehicles and 15% of transport emissions. There's a significant segment of the transport fleet that's ready for electrification NOW and the trucks are available globally today.
Heavy haulage trial success
Holcim, along with our partners CHL and Janus Electric we have achieved an Australian first – the first zero-emissions heavy vehicle delivering raw materials.
GEORGE AGRIOGIANNIS| CEO, HOLCIM AUSTRALIA AND NEW ZEALAND
A single urban delivery truck emits as much as several passenger vehicles. So why aren't they electric?
Switching to zero-emission trucks would be the fastest way to cut emissions, but they've largely been left out of the national EV strategy. Here's what's holding back the uptake.
Bought as work and family car.
Travelled 30k 12 months.
Driven to Carnarvon on stations and throughout the Mid West. Up to 900km day trips.
We have 6.6 kW solar at home. Solar and EV’s a great combo.
I am home a couple of days as have home office. works well for solar charging.
It’s an amazing car to drive. Instant acceleration, minimalist styling. It feels like a space ship.
We get up to 450 kms. Drive fast into a head wind and this would be 350kms.
If DC fast 50kw + charging is fine.
Fitted towbar. This worked well for bikes, spare tyre carrying and towing.
Towing reduces range by 30+ % at Hwy speeds
Can just do this trip without a charge, but with new Fast charger it will be a stop for most EV’s (15-30 mins).
No fast chargers in wheatbelt towns. This is ok if staying the night, but limiting otherwise.
I got back from Morawa with 0% one day.
It would actually be easier for people living in wheatbelt towns to commute to Fast charge hub towns up to 400 ks away, charge up and go straight home.
Tesla Model 3 Long Range 2022
Great driver tech
Glass roof in summer, Air cond suffers
Dust seals could be better.
Fast incredible handling.
Auto pilot ghost brake
Good boot space, frunk, cabin
Perth for service
EV range is expressed as WLTP by manufacturers. In a nutshell it provides a best case range.
Expect highway range to be 25 -35% less than what manufacturers state.
- Big deal? Not really.
- Drive slow and you can go a LOT further!
Things affecting range range in the Mid West
- Coarse, rough roads
- Highway driving
- high speed = more power use
- Less regenerative braking benefit
- Tesla’s supercharging network - not as relevant for regional WA.
- Local service - If something goes wrong, you’re off to Perth with a Tesla.
- Spare tyre - none of them
- Glass roof - Hot!
- Vehicle to load -Not Tesla
- Efficiency 15Wh/100km Model 3 / Ioniq 6
- OTA updates
- Accesory compatibility eg. Tow & Roof racks
Tesla Model Y is first EV to be the worlds best selling car. An ICE car will never hold that spot again.
There is now a secondhand EV market in WA. You will find reasonably priced Tesla Model 3’s as some people have decided to upgrade to the roomier more SUV like Model Y.
- Ev’s are getting cheaper while ICE cars are getting more expensive
- Second hand market is emerging

- Slow charging - standard 240 outlet through to install charger.
- Fast charging - DC more below
Level 1 / Mode 2
Existing power point (10-15 Amp, single phase), used in combination with a specialised cable which is typically supplied with the vehicle.
Typically used in standalone domestic homes.
This method will add between 10 and 20km of range per hour plugged in.
It will top up daily use, but will not fully recharge a typical pure electric vehicle overnight.
Level 2 / Mode 3
A dedicated AC EV charger at up to 22kW (32 Amp, 3-phase).
Typically installed in homes, apartment complexes, workplaces, shopping centres, hotels, etc – anywhere the vehicle will be parked for a while.
This method will add 40 to 100km of range per hour of charging depending on the vehicle.
It will top up average daily vehicle use in an hour, or deliver a full recharge overnight.
Level 3 / Mode 4
A dedicated DC EV charger at power levels from 25kW to 350kW (40 – 500 Amp, three phase)
Typically used in commercial premises and road-side locations to provide for faster recharging than Level 1 and 2 can achieve.
At the lower end, this method will add up to 150km of range per hour plugged in
At the upper end, this method can fully recharge some electric vehicles in 10 to 15 minutes
WA EV Network | Australia's Longest Electric Vehicle Network
Australia’s largest EV charging network is coming in 2024. 98 EV stations are to be installed across WA from Kununurra to Eucla. Learn more today.
A 6.6 kW home solar system is the largest size for a single phase house in WA.
Ideal would be 3 phase 10 kW ++system.
The 6kW system will will generate around 27 kWh/day.
Model standard Range battery 3 battery 50 kWh.
You can put 100kms + of your daily home solar into your car if slow the charge rate down.
They key to getting value out of a home Solar system it to use that power, not export it to Symergy. Why solar feed-in tariffs are plunging while electricity prices are soaring
What about Hybrids?
- ICE motor charges the battery often termed “self charging” 🙄
- 6l/100km. 100g co2 - better, but not good enough
PHEV - Plugin in Hybrid
- Once battery used 50-80km, economy worse then ice version
More complexity and maintenance.
Cheaper than Model Y, but Y?
Most Hybrids still 2t Co2 per year and over 20t in lifetime + still polluting
Most companies pushing Hybrids don’t have a pure EV to sell. Toyota
Toyota chief criticised for self-charging hybrid claim by Hyundai
Toyota is accused of being 'disingenuous' in what it is saying about hybrid vehicles.
Top Toyota Scientist Says World Lacks the Resources to Go All-EV
Toyota Motor Corp.’s top scientist warned that transitioning to electric vehicles too quickly could lead drivers to hold on to old gas guzzlers and called for hybrids to be given a longer leash ahead of a Group of Seven leaders summit in Japan.
What happens to the batteries?
Recycling EVs - most batteries are still on road https://www.forbes.com/sites/carltonreid/2022/08/01/electric-car-batteries-lasting-longer-than-predicted-delays-recycling-programs/
Will the grid keep up with EV demand?
EV’s will have a major impact on energy demand.
Off-peak charging rates will help manage loads.
EV’s will eventually provide battery backup to the grid. V2G
Will my EV catch fire?
What about the Cobalt and other dirty supply chains?
Most batteries are now LFP Lithium Iron phosphate - no nickel or cobalt
Aluminium is a big part of an EV and it requires a lot of energy to make.
Should I just keep my old car?
New cars are expensive full stop.
The role of business incentives is get EV’s out there and create a second hand market.
Our cars keep polluting. An EV will break even on embodied emission in a year or so.
An EV will provide lower cost, climate safe motoring in the long run.
Avoid a flight instead?
A family of 4 return flight to Bali is 6t emissions
Driving less is still best!
Perth traffic with fossil fuel cars
Perth traffic with electric cars
There is enormous potential for more Australians to get around in active ways. More than two million trips taken by car every day in Sydney are less than two kilometres in length, while in Melbourne half of all weekday trips are under 4.7 kilometres and most of these occur in a car.
