Enginer PHEV Conversion.

I'm new....is that available for a "C"? Can you point me to a website that would more information? Would love EV mode for 12 or 15 miles or so....

 

Plug-In Supply | Plug-In Conversions for Prius and Escape

 

there is a thread here on a prius c pis conversion. almost a year old and still not finished as far as i know.

 

So there's a plugin supply that works with the car? Does it work just like the Prius Plug in?

 

no.

 

try pm-ing the guy who is installing one in his 'c'.

 

I bought my aftermarket Prius Plug-In conversion kit, or add-on battery pack, from Plug-In Supply about 1.5 years ago. I did the do-it-yourself method to save on $$$. I had some problems at first since I'm not an amazing engineer. Soldering is not my forte. I killed a few boards but the owner helped me out and got me up and running. Still it was worth learning how it all works by putting it together. I spent probably 4 nights assembling the battery pack and then 2 weeks to do the car install. I got a 10KW system in my car working within two months of purchasing and have been saving on gas. I get over 85+ MPG and I am a VERY aggressive driver in CA. Sometimes I get over 70 miles in range on the 10KW system because I think the cells I got made the pack around 12kW. When I drive around town in the suburbia it is 100% EV and I can get 150+ MPG. The owner, Robb has helped me on the phone many times and is very knowledgeable about mechanical engineer, batteries, and his proprietary system. I am glad I went with Plug-In Supply and not Engineer. I would suggest you take a look at the plugin supply website before going with Engineer. I think Robb still does FREE TEST DRIVES personally, if you are inside the USA.

 

Pics or it didn't happen.... I'm skeptical... the LEAF with a 24kwh battery gets around the same range...

 

I just bought a Plug-In Ford C-Max Energi. It was $10K over the Prius C 3 I had, but it's twice the car too. It has a 7.6 Kwh battery. I'm currently getting 20 miles per charge, but people are getting up to 28. Adding a system to the car is a great idea, but if you're not capable of the build, setup, install and configuration work, you might just buy a plug-in and be done with it. You won't save any money either way and the factory plug-in has the warranty, plus you get the tax incentives to off set the costs. Hacking an electric vehicle isn't for the DIY'er and the costs are way to high for a comparable setup with a limited warranty. If your vehicle is hacked, you loose the manufactures hybrid warranty coverage

 

It's akin to the exaggerated MPG numbers some people claim

 

Agreed... I don't mind seeing it and if people do it, more power to them... However, as far as anybody on this forum knows, nobody ... repeat ... nobody has done a conversion to a C. Especially not with the type of energy density that he is bragging about.

 

Yep! Lots of embellishment and exaggerated EV claims on the interwebz

 

oh crap, i can't do math, or can i?? here's the calculations ...

76 cells Sinopoly 40ah = 3040 amps * 3.2 V = 9728 watts ~= 10kW

but when I measure the cells during a charge they go up to 3.6 V (where i live) so if you calculate all full charge and not some average bell curve (3.2) then you get...

76 cells Sinopoly 40ah = 3040 amps * 3.6 V = 10944 watts ~= 11kW

sorry, i mispoke about the 12kW, but I think the Chinese battery manufacturing is not 100% exact science and because I'm getting more that 70 miles, I believe they are not 40ah, my guess is 42 ah, and if they were the math would be:

76 cells Sinopoly 42ah = 3040 amps * 3.6 V = 11491 watts ~= 11.5kW

then you have to calculate the number of watts per mile, and i think for my driving i'm getting about 160 watt/mile

11491 watts / 160 = 71 miles

i don't get that all the time, sometime i get only 50 something miles on a full pack and that would mean i'm using 200 something watts / mile (WPM), not words per minute for all you speedy typists.. i think i said sometimes...

i didn't mean to make that "embellishment", it's more like 11.x kW, but we can call it 10.5kW if that makes you feel better. if you want to research the sinopoly they have a chinese website, use google translator and look for SP-LFP40AHA on sinopoly battery website on the product batteries page.

also, i don't have a way to calculate the watts / mile yet, but i'd like to find a way or make a way so i can track this. Instead of MPG, we should be looking a WPM (watts per mile). i'm thinking about making some arduino or raspberry pi mobile app to track the data i want using sensors and sending over wifi to mobile device... like the torque, but for my BMS and EV usage...

and pictures of my pack for all the non-believers...

 

The embellishment in question was your miles per charge, not your pack size or that you had a pack. I've seen many conversions on Gen 1 and 2 Prii, but none with your range from such a small battery. Either those are the most expensive batteries ever (to compensate for the energy density), or your entire trip is downhill.

 

oh, i see, well they were expensive batteries... i think i paid around $8K for the DIY around 1.5 yrs ago, but i just checked and it seems prices have come down to under $7k for the same thing i got. 10KW prismatic.

i don't think it is very hilly, up or down, when i get the 70 mi range. it's usually flat and mostly city driving, or if i get on the freeway i accelerate to 72 MPH and glide from there, nurse it, pepper the momentum and FLOW, so it could be my skill as an EV driver! ;-)

 

You are the best driver ever then... 70 MPH in a LEAF will net you 68 miles... and like I said, it's twice as big. If you can do it, great... but I'm still skeptical, no offense.

 

no offense, i think we have to agree we are comparing apples and oranges... when i say my pack lasts over 70 miles in range on a single charge, that is using mostly EV but the Prius Gen2 does have to spin the ICE (internal combustion engine) at 34 MPH and i use a small amount of gas to accelerate. so i'm driving a hybrid in blended mode when i get this range, but i can get 85 MPG on average with lots of HWY driving and over 100+ with CITY. i have to admit, i have never driven a LEAF, but i think you are pure EV. So what you are saying makes sense since you are 100% all electric and i'm hybrid. personally, i like the freedom of my hybrid because i take the prius on long drives without worrying where i will fill up and charge (of course i go back to normal 45 MPG when i run out of charge). but i go snowboarding every year in utah, lake tahoe, and parts of CA and the prius let's me go without worry.
