Convert your Toyota Prius to Plug-In hybrid with our conversion kit?


If you own Toyota Prius hybrid car you can convert it to plugin hybrid with litium battery back 4-14kWh, BMS, battery charger and control boards. You can charge your car for example via standard 230V AC trough Defa or Galix -plug. With converted Prius you burn less gas and get three additional plugin drive modes to your vehicle. Short distances can be drived totally electric.
We have developed, updated and tested our Pistokehybridi Prius conversion kit eight years in Finland. You can even do conversion yourself with our DIY kit.
We have two conversion kits. Full Kit for 2004-2009 Toyota Prius and Lite Kit for 2010-2016 Prius.

Full kit have three additional drive modes:

1. Full EV (Top Speed 85km/h)

2. EV mode (Top Speed over 100km/h), Combustion engines is in idle mode 

3. Combine mode, use both electric motor and combustion engine to get about half fuel consumption 

4. Emulated hybrid mode with better regeneration

What battery cells can be used with Prius Plug-In conversion?


Prius GEN2  Full plugin Kit original Prius NiMH cells are not needed anymore and they can removed (this save wight about 30kg)

We think that best way is to use used LI-Ion cells from broken EVs, like Nissan Leaf or Mitsubishi IMiev used cells. Those have balanced quality and prices are reasonable. You can also use new or used Li-Ion cylinder cells for small capacity battery and 50Ah or more capasity new LiFePo4 cells.

We recommend 68 lion cells in serial (can vary) or 78LiFePo4 cells.

For example using 34pcs used Nissan Leaf battery modules you will get about 11-14kWh battery capacity. You can also order Leaf battery modules from us. We transport to most European countries. 34pcs Leaf modules price is prices is between 2500-3000€ VAT 0% depending their Stage of health value (VAT24% will be added to prices if not company with EU VAT address + shipping).
