From oil dependence to local resilience

Will NZ have to wait for 'plug-in hybrids' before electric car users can get real energy efficiency, as on long rural runs between cities the hybrid (such as Prius) uses mostly petrol and is less efficient in fuel use than a modern diesil engined car. In cities with stop-start movement to recharge the battery, the hybrid is more efficient than petrol and less polluting than diesil. Any thoughts?

The technology and electric cars have been built now that have 400km range and can be recharged in 10 minutes. top speed 140km/hr...

We have test driven this vehicle first hand and the high speed charge station.
The Electrical distribution network is already in place and in NZ 65% renewable already

The only issue is availability. The car companies are holding back...
there is to much invested in the "Status Quo" .....


We currently have in stock in NZ electric Personal transportation with range of 75km.

And can discuss Plug-in Hybrid upgrades with owners of existing hybrids.

So we have to convert existing cars our selves
How many KWh of power are required to drive a car 100km? Thus, how many units of power do you need for that journey? If using a hybrid, it would be a mix of electric and petrol, but what fuel requirement alongside the electricity? Would it be technically easy to fast charge at (say) cafe parking areas using a credit card payment system, as an alternative to petrol stations, and thus get away from reliance on oil company sites?

There is an Australian company now Retro-fitting new Hyundi Getz with electric power. They get 120kms at up to 100kph -- adequate for around town between charges overnight. But will always be limited in terms of rural distances.

They're trying to build a market with Oz city councils and govt departments to get the economies of scale, but at the moment its pricey!

Check out Blade Electric Cars
about 3-5KwHr per 100kmHr.

Note the Solar Taxi www.Solartaxi.com is reporting 8kwHr / 100 km
on its around the world journey ( with Trailer!!).
That is energy equivalent to 0.8 litres per 100 KM !!!! in energy terms.

1 litre petrol is approx 10 Kw/Hr of energy!!

Electric Motors are 80-95% efficient.

Internal Combustion Engines in cars only achieve about 13-20% (avg 17% )
so most of the energy never get to turn your wheels!!! IT is WASTED as heat!!

Plug in Hybrids in USA are achieving 125MPG.

1. Basically a standard Hybrid (PHEV) (4.5 litre/100km ) will halve fuel costs from simliar size gasoline car.
2. Plug-IN Hybrid will Half the Gas consumption again (2.7 litre/100km).
3. Pure EV energy equivalent of 0.5-1 litre / 100km 5-10 Kw/Hr

FAST charging (10 minutes) requires specialist equipment and anyone who has capital to install these eg Supermarket / Cafe / independant gas station / Power Company.
I doubt the Oil companies will install them!!

Regular charging (1.5-2.5 hrs) can be done on any Power point you can find. eg Your Garage overnight
