An Australian engineering firm called Enginer has launched a Plug-In Hybrid Electric Vehicle (PHEV) kit to suit Toyota Prius at the Hybridfest Green Drive Expo held in Madison Wisconsin. The battery conversion kit from Enginer comes in three versions, a 2 kWh version which costs $1,995 and a 4 kWh version which sells for $2,995 and a DIY kit without batteries for $995.
As a benchmark comparison the Hymotion PHEV kit from A123 systems consists of a 5 kWh (3.6 kWh usable) battery pack and costs between $9,995 - $14,500.
The 2 kWh pack will give an EV only range of 10 mile to your Prius while the 4 kWh pack give 20 miles EV mode range. The kits use Lithium Phosphate batteries similar to those sold by Thundersky and BYD with all parts sourced in China.
The Enginer kit is sold in the US by Detroit based Automation Tech Inc. and the first PHEV Conversion Kit suit both Gen 1 & Gen 2 Prius. The proprietary technology is designed for simplicity, no hacking into the computer and force the battery into electric mode is required. Instead they focus on supplementing and charging the standard NiMH battery stack, resulting in only 5 wires integrated into the car and an installation time of 2-3 hours. Because this is a supplemental battery pack it can also be installed in most other Hybrids.
We have seen some Prius drivers with the Hymotion Plug-In conversion achieve up 300 MPG so depending on driving patterns these PHEV kits can pay for themselves in a short time.
