Green Auto Conversions is dedicated to improving the environment by offering plug-in hybrid conversions to owners of the popular 2004-2009 model (Gen 2) Toyota Prius car.

With the Prius, Toyota has done an incredible job in introducing the most effective and far-reaching change in automotive technology in the past 100 years. This car can use either petrol or electricity (or both together) as fuels. Electrical energy is stored in a modest sized high voltage battery charged from either the petrol engine, braking or from descending hills. Recovering energy in this way allows the Prius to go twice as far on a tank of petrol as normal cars of a similar size. Fuel economy of 4.5 litres per 100 kilometres is common, even in heavy traffic.

A plug-in hybrid conversion from Greenauto takes the Toyota design to its ultimate conclusion. The high voltage battery is replaced by a large 10Kwh lithium iron phosphate (LFP) battery that is charged from the electricity grid. Power from the grid is much cheaper than power from petrol, the price of electricity is highly stable and, if renewable energy is used, your carbon footprint is greatly reduced.

The resulting plug-in hybrid electric vehicle (PHEV) connects to any normal 240 volt AC power outlet and typically charges in hours, drawing less current than a two-bar radiator. With a full charge you can travel in pure electric mode for typically 80 kilometres or mixed petrol/electric mode for around 160 kilometres. In pure electric mode, a minute amount of petrol is used to heat the engine and speeds up to 100Kms/h are possible. Output power is however restricted by the capacity of the electrical drive system. The petrol motor will add power if the accelerator is depressed sufficiently. This mode is ideal for city driving.

For country or freeway driving, mixed petrol/electric mode is preferable. This provides the car's full 55Kw of output power, there is no inherent speed limit, and petrol consumption is around 2 litres per 100 kilometres.

If this all sounds too good to be true, there is a catch. At present the price of high capacity LFP batteries is not cheap and thus the cost of a conversion is relatively high. At present it is unlikely you would recover the cost of your conversion over the lifetime of your car, however if you are seriously concerned with the state of the environment and the direction fossil fuel burning is taking the planet, Green Auto Conversions offers a remarkable and unique service that allows you to be an early adopter of technology that may well help save the world.
