Turnbull backs EV claim

“Bill Shorten’s claim [that] electric vehicles could be fully charged in eight minutes has received backing from … Lucy Turnbull“.

Shorten’s widely ridiculed claim appears to have found support from Mrs Turnbull. The chair of the Greater Sydney Commission and wife to Malcolm Turnbull shared an article on Twitter yesterday from the website Renewable Energy World, heralding the launch of ‘the world’s fastest e-vehicle charger’ which could charge up to 350 kilowatts — or 200kms — in eight minutes.

Very exciting ABB Launches 8-minute Charger for Electric Vehicles – Renewable Energy World

We checked her source, Renewable Energy World, which wrote this nonsense:

The Terra High Power charger can charge up to 350 kilowatts, which translates to about 200 kilometers of range for an EV, in just 8 minutes, according to the company.

Comment: Kilowatts is a measure of power, not energy. By comparison, a Tesla battery can hold around 85 kilowatt-HOURS and can be fully charged in around 75 minutes at a supercharging station. If they mean that the ABB device can charge at the RATE of 350 kilowatts, then it is feasible to charge a battery with CAPACITY of 85 kilowatt-HOURs in 85/350 hours, or 15 minutes. The problem is that such a battery doesn’t exist. So now we know where Shorten and Turnbull got their data from – a loony-Green site which doesn’t know the difference between power and energy

We tracked down the ABB product announcement too, it says:

  • 375A output current per power cabinet to charge at 400 VDC
  • Scalable installation …
  • Modular system, charging powers from 175kw up to 350kW

Source: High Power Charging | ABB

Translation: So EACH power cabinet, if 100% efficient, could produce a maximum of 375A x 400V = 150kW. By SCALING the installation, i.e. combining MULTIPLE cabinets, up to 350kW could be produced – but they wouldn’t be charging the same EV.

The next question is:

Where does the power come from?

The Tesla motor has an efficiency of 93%, so it is reasonable to assume to Shorten/Turnbull’s 50% of vehicles which are electric are Tesla’s. A Tesla has energy storage of 85kWh (and an effective range of 320km when charged to around 80%).

If half of the 20 million vehicles in Australia have 85kWh batteries, then the total battery capacity of these 10 million vehicles is 850,000 MWh.

If each of these 10 million vehicles is charged each day, and half of the the charging occurs during a 2 hour peak (when people get home from work), then the power supply needed is 50% x 850,000 MWh / 2 hours = 212,500 MW.

Next question:

How many of Malcolm Turnbull’s Snowy 2 schemes are needed to charge these vehicles?

Snowy 2 is planned to provide 2,000 MW of base load power, charged up by ‘renewables’ when the sun shines and the wind blows and generated by running water downhill through turbines during the peak 2-hour period.

So we need 212,500 MWh for the 2 hour peak and each Snowy 2 will provide 2,000 MWh, which means we need 106 Snowy 2s.

At a cost of $12b each, the cost of the pumped-storage alone will be $1,272b, or in round numbers $1.3 trillion. We sill have to add the wind farms, solar arrays and the other rubbish.

Last question:

How many Coal-fired power stations are needed to charge Bill Shorten’s Electric vehicles?

If an 800MW generator set costs around $2b, then a power station with 4 gensets will cost $8b and generate 3200MW. 212,500 MWh divided by 3200MW suggests we need around 66 coal-fired power stations at a capital cost of $528b. This is the capex only and doesn’t include running costs, the fuel supply and power distribution network.

These monkeys think that you’ll charge your EV at home. Try to imagine a 350 amp x 400 Volt charger running off the solar array on your roof.

Where is Bill Shorten’s ‘plan’ to build 66 Power stations?
