PIS 10 Kw kit - what is the real world range in EV mode?

I don't have the PIS kit (I have Enginer), but based on my experience, the "range" in EV will vary quite a bit based on many factors: outside temp, terrain (hills), driving style, speed, A/C use, stop frequency, etc. Look at the variations in range the Nissan Leaf is seeing (anywhere from <50 miles to 120+). I can get ~5 miles/kWh pretty regularly with my commute (where I get 120-150 mpg, so mostly EV), but it is pretty EV friendly in general. If your commute terrain is fairly gentle and you don't drive aggressively, 50 miles is realistic, but in general you will probably get a bit less.

Let me put it this way, PIS is going to advertise on the high end of the range.

Hopefully a "bona fide" PIS client will chime in soon....

 

I use this website to determine what range I could get with a 10kw battery results: 24mph, 44 miles EV

No it does not. The best I can do is use the built-in Prius functionality and then I use an engine temp spoofer to minimize ICE use. So I am no help for high-speed EV. Efficiency will obviously be much worse, though.

Note that the Nissan Leaf has a 24 kWh battery and gets typically 80-100 miles. Granted it's a different car altogether so it's not apples to apples. But that's more like 3-4 miles/kWh or less. So again, this is pointing to 5 miles/kWh being on the optimistic end of things.

 

and leaf is 24khw.. not 10lhw

add another 14kwh and what do you get wth the prius 3500? 3600 also?

 

The "Soup Nazi" from the Seinfeld's show once said...NO SOUP FOR YOU!!!

 

Are you sure you are not referring to Jim335 getting 28miles EV out of his PiP that he add a 4KW system to?

 

BestPal,
I believe if the PIS kit was everything they say it is, there would be numerous posts on here touting its success. I have done so much research on it and have concluded the following:

1) I have found no examples of people receiving the "High Speed EV" mode (shown on their website) with their system
2) EV only mode on the Prius is limited to 52 mph. This is only achieved by cutting power to the fuel pump to make the Prius think its out of gas. This in turn, lights up numerous errors/warnings on your dash that have to be cleared each time pwr is cut to the fuel pump. You simply won't be able to drive with all the warnings and buzzers going off.
3) Once pwr is cut to the fuel pump, the only way to get the ICE to come on line (when the battery gets depleted) is to pull over, turn the car off and back on
4) Acceleration is severely limited in "EV only mode" to the point where its dangerous in moderate to high traffic conditions (acceleration gets you out of as many accidents as braking)
5) The Gen II Prius is not designed for EV only operation. The engineers designed the Gen II with the idea that it is a gasoline - primary, electric assist car. This is why it won't operate in EV mode during takeoff (exc. anemic takeoffs) or speeds above 42mph. For this reason, you end up with an anemic EV car that still wants to use the ICE regularly.
6) The Prius (all) are designed to limit emissions first and for fuel economy second. The highest priority for the Prius is limited emissions (not fuel economy). This is why the ICE runs when you first start the car and continues to run until the cat converter is fully warmed up. It is also why you get 25-40 mpg's during the first 5 minutes of operation.

Basically, for a freeway commuter, the stock Prius is "maxed" out for FE. I know PIS website says improved highway mpg but, where are the real world reports?

By comparison, I think Enginer and PICC have better approaches when it comes to PHEV mod of the Prius Gen II. Enginer modifies very little but constantly recharges the OEM batt pack resulting in improved city mpg's. PICC completely replaces the OEM battery with a more robust pack and other mods.

My advice is to not mod the Prius and be happy w/ what you got but, if you insist on a PHEV mod, I would recommend Enginer or PICC.

 

BestPal, Hopefully I don't get to many members grumbling at me, but would a Nissan Leaf better suit your needs?

Just curious, and giving a suggestion.

 

Just another data point to think about. The 85-kWh Tesla Model S is around 4600 lbs. The range advertised by Tesla is 300 miles (@ 55 mph, flat road, no wind, no climate control, total mass around 5000 lbs) or EPA's 265 miles.

A Prius with a 300-lb 10-kWh system is around 3100 lbs. Let's assume the electrical systems are similar in terms of efficiency, then we have 85 kWh / 10 kWh = 265 ~ 300 miles / [X] miles.

[X] = 31 ~ 35 miles

Adding a driver's weight and considering the fact that Model S has a slightly lower Cd, [X] is probably closer to 30 miles ± a few miles (around 50 mph, flat road, no wind, no climate control).
