Basically a Hybrid Plug-in Conversion has either additional
batteries or larger replacement battery installed in the
vehicle, plus the addition of a battery management system and
also a charger mounted in the vehicle to charge the additional
or replacement battery pack.
Because of the
lack of availability of any/decent commercial Plug-in hybrids,
many companies around the world are producing "Kits" for
converting the standard Toyota Prius to Plug-in. Note: The Toyota Plug-in Prius is not on sale in Australia,
only in the US, Europe and Japan.
EVPlus is, at the moment, analyzing the different
plug-in converting systems available from around the world. The
type of hybrid EVPlus will be concentrating on, in the
initial stages, will be the Toyota Prius, and in particular the
Generation 2 (Gen 2) model produced from 2004 to 2009.
CONSULTATION SERVICE EVPlus does not
do conversions for other people.
EVPlus will consult with you and assist you with your
Direct assistance will generally be with those in the
metropolitan area of South Australia. General advise will be
available to anyone with a question.
Extensive consulting will require a fee via PayPal.
PLUG-IN KIT PURCHASING EVPlus does not supply kits for conversion.
The system that has been evaluated is the Plug-in
Supply "10 KW" kit or parts there of.
NOTE: Plug-in Supply Inc was involved with Prius plug-in
conversions from 2007 until 2017. They have now closed that part
of the business, and will not be supplying Prius conversion kits
I have a Gen 2 Prius which I would like to convert to plug-in.

Please let me know when the conversion is available in Adelaide as I am
ready for it now.

This website will be updated as soon as the 10kWh systems have

How will you go having a voltage range 213- 304 Volts in the Prius.
Does the battery charger you are expecting control a steady amp flow
- not voltage .?

I have a permanent monitor on the Prius standard battery, as it is now,
and the maximum that I have seen is around 260Volts. I have never seen
This monitor also shows the charge (regeneration) and discharge current
of the battery pack.
The minimum that I will run the combination of batteries will be to
around 20-30% state of charge on the additional cells before switching
the additional cells out of circuit.
I have purchased an Ah meter (separate to the US kit) which has relays in
it so that I will be able to set a minimum state of charge and use one of
the relays to interrupt the BMS loop to disconnect the additional cells
at this predetermined state of charge. This is my idea (not supplied with
the US kit) as I don't want to rely on the unit waiting for the cells to
reach the BMS low limit of around 2.6 volts per cell - which would be way
lower that 20% state of charge.
Once this happens, the Prius reverts to a standard Prius using only the
original NiMH battery.
The additional cells then remain disconnected from the Prius pack until
they are charged again - as I understand it.
The charger will be of the constant voltage/constant current
sequentially. (3.65V max per cell)
I think it will work perfectly with the combination of batteries.
