Plug-In Conversions and Modifications
Our Conversion System for the Toyota Prius (2001-2008)
We offer 3 types of conversion kits for sale and installation. Each kit is different and will give the consumer a different product and price level.
The 10.2 kW Plug-In Supply system is the biggest battery pack that can fit into a Toyota Prius. It fits the Generation II vehicles (2004-2008). The 10.2 kW Lithium Iron Phosphate kit will completely transform the Toyota Prius into a fully electric vehicle for up to 40 miles. This type of conversion is great for those looking for the ultimate in a PHEV conversion and those who wanted to buy an electric car, but choose to have a more reasonable approach. The 10 kW system is also great for those who make frequent stops (such as a postal carrier) or commute in the city, but want an interstate car that can take them wherever they want to go and without stopping to charge up the battery. This system costs $11995 + shipping.
The 4 kW Plug-In Supply system (2004-2008 Prius) weighs significantly less and does not require a rear spring upgrade; this Lithium Iron Phosphate kit does not change the handling of the car that is often associated with a lot of weight behind the rear axle. This kit is more cost effective and still has the same consumer control features as the larger 10.2 kW system; such as engine run time control and system switching control. This system costs $7995+ shipping.
Both of the Plug-In Supply systems are purchased directly from the company and installed at our facility in Monticello, Minnesota with ASE certified and factory trained technicians. For details and a product comparison on the Plug-In Supply products, please refer to their website. The installation cost is $1000. The warranty period for Plug-In Supply conversion systems are as follows:
- 3 years parts and labor on installation, diagnostics, controls, and circuitry.
- 1 year parts and labor on batteries
We also offer a third, more economical option for the Toyota Prius. This system does not allow the consumer the full control and option of a totally electric vehicle, but it does have similar components that allow for more electric drive and less gas drive.
Our Conversion Systems for the Ford Escape
Currently, there are no readily available Plug-in conversion kits available for the Ford Escape (or any other hybrid besides the Toyota Prius for that manner). Twin City Hybrid is working with several companies that have conversion kits under development. We hope to be able to offer a reasonably priced conversion kit for the Ford Escape and the Toyota Camry very soon. Contact us if you have any questions or would like to be notified when these are available.
The Conversion Process
After contacting a company technical representative, the consumer will be brought out to the installation facility to view the tools and equipment used in the process as well as to test drive a converted Prius. We want to make sure that each customer has the opportunity to fully explore their options and make an informed decision. We walk each customer through the process and answer any questions they may have.
Once the customer has decided that a PHEV conversion is for them, we arrange a drop off date. The installation and testing process can take as long as a few days. We schedule this very carefully so that the consumer is not inconvienced by the process.
Economics 101
The costs of converting a vehicle to a PHEV should not be taken lightly and without consideration. A PHEV conversion:
- Is a great investment in a vehicle
- Retains it’s value during a resale
- In many cases it is portable from an older vehicle to a newer model
- Will significantly decrease your fuel consumption
- Relies heavily on a more stable and domestically produced energy source – electricity
- Does not change the normal operation of your car if removed
- Does not interfere with the manufacture’s 8 year/80,000 mile emissions component warranty (high voltage battery pack and related components)
- Extends the time between oil changes
- Extends the life of the engine and brakes (as they are not used as much)
The payback period of the installation of a PHEV conversion system can vary from 3 to 6 years. The differences in kit choice, driver inputs, and vehicle usage are strong variations that will affect the timetable.
Twin City Hybrid offers plug-in conversions for existing hybrid electric vehicles. A plug-in conversion adds an extra battery pack to the vehicle. This extra battery pack is charged up by connecting it to a standard 110/120 volt household outlet.

Twin City Hybrid can convert a Toyota Prius (and many other cars) to a right hand drive vehicle for a reasonable cost. The Prius (and other hybrids) makes a good choice for rural mail carriers because they were designed for heavy stop and go traffic. The fuel mileage on a hybrid is best when doing this. Twin City Hybrid can also install right hand drive conversion kits on other vehicles. We are a perferred dealer of
