As a current Prius PHEV driver (for over a year) and a firm believer in "KISS"
(and an Electrical Engineer), I've decided that it is time for my wife to enter the world of EV'ing via a very simple Prius "upgrade" from Hybrid
-Electric to All
First, let's look at her driving habits: She is currently driving a 1994 Honda Accord that she drives about 5000 miles a year in our neighbourhood to visit friends and for some "retail therapy". Yes, it would be much more affordable for her to call a taxi. But, I want to retain her as my wife, so that isn't going to happen. She never drives on any 4-lane highways; she never drives during our frigid Canadian winters (January to April); and she never drives over 30 miles in a day (averaging about 22 miles/day) with a typical speed around 45 MPH.
I have a wonderful friend, Mony of Autodex Hybrids
, who has gotten me a recyled, rebuilt white '05 Prius in perfect shape and is prepared to rip out the engine, gas tank and exhaust system for me. He also has already installed a used Hymotion L5 Li-Ion nano-PO4
battery kit and has two 4 kWh Enginer Li-Ion packs
destined for this conversion.
So, what I will end up with is a Prius (or I should say an e-Prius
) with a 50-mile radius (almost double her average requirement), top speed of 52 MPH and acceleration of 0 to 40 MPH in 15 seconds using the standard Prius 50 kW motor/generator set, CVT, converter/controller and S/W along with 13 kWh of additional battery energy in addition to the 1.3 kWh of OEM NiMH battery. Regen energy will still be restricted to only the OEM battery. Please see http://www.EVAlbum.com/3497
A custom template will hold the CVT Engine input from turning and one of the Enginer packs will sit in the Engine space. The other Enginer pack will reside under (or in lieu-of) the back seat, while the Hymotion pack is beneath the trunk, replacing the spare tire.
Totally meets the specs required for my wife's driving habits, don't you think?
So, I feel that my only problems are driving in our Canadian December
(around 25 to 35F); driving in July (around 80F); charging 3 separate battery packs each with its own charger but, mostly, smoothly switching the source of power from one battery pack to another.
What do you think?
