Daox's Enginer PHEV 4kWh install

Hi Doax,
The install manual has been updated with a picture of the connection. Does this help?



I think turning on the Enginer switch activates EV. But if you go too fast and drop out of EV then you need to turn the switch off and then on again to get back into EV.

I did the EV Hack separately to the light flasher. This was esay and now if I flash the lights, the EV comes on. So I will not connect the Enginer systen to the EV.

Thanks,

Hi Dan,

I was under the impression that Enginer did not officially endorse using OEM EV mode (I remember reading something about not aggressively pursuing electric mode on their website). So the official installation manual includes instructions for hooking up the EV switch? Does it always activate EV mode immediately after turning the system on regardless of whether or not the engine is warmed up?

Hi Andrew,
I think you are miss-informed on this or maybe have just miss-stated what you had heard or believed.

The EV Hack is common knowlege for Gen 2 cars. This is covered in other threads. All the Enginer system does is to include this in their Gen2 kit.

The car will act just like the Europian or Japanese Gen2 Prius does when the EV button is pushed in those cars.

Thanks,
Dan

 

Forgive me, I understand how it works--I have an OEM EV button in my vehicle as well. I just wasn't aware that Enginer actually officially used it...So people with the Enginer system--when you engage the system it will automatically activate the EV mode relay for OEM EV (meaning its tied to the activation switch)?

The reason I ask was I remember reading FAQ #4 on their website which says they don't pursue EV mode. I know most people who have said conversion kit install an EV button, I just didn't realize that the EV mode relay switch was a part of the official installation process...I was just curious.

Hi Andrew,
I think you need to go back and read the FAQ before making comments about it.

However,:focus:
Please lets not Hijack Doax's thread going on about EV. If you want to continue this discussion you can send me a private message or you can start or find an EV thread to do this on.

Thanks,
Dan

 

I believe I did read the FAQ's, hence why I asked my question...but anyway, I didn't mean to hijack anything or make anyone upset =). I was more interested in feedback from someone who had the system installed (hence the relevance to the thread). I only asked because it came up on the thread...

Anyway, feel free to PM me if anyone wants to respond or feel free to ignore me...that's cool too =).

And Dan, just for you....:focus:

Andrew, I think that the are many new faces in the forum trying to know everything at once.
I remember the good old days wen we were a handful of Prius owners nationwide starting the PHEV movement and integrating electrical modifications to our hybrids and EVs......:rockon:

 

All of our failures have been at the top. The cases actually cracked in some of them. Once they experience this sudden large jump in voltage while charging, they also drop suddenly on the bottom end.

 

100% is that the ORANGE safety disconnects was not installed propperly and latched.
More like;y, you will have to cycle the car on and off 3 times to erase any warning signs on the dashboard, and that will keep you going again.

 

Hi Doax,
The balancer Lee is doing is for lead acid batteries at 6v and 12v. It will be much harder to get Zieners to act the way we would need at 3.75v with the tolerance we need. In addition the bypassing of a cell means that the pack voltage that the charter needs will drop while the charger is in constant voltage mode. This will drive the charger crazy. It would be important to have the charger design match to the type of balancer system. This then becomes a more expensive BMS.

Thanks,

If the OEM Battery voltage is high, you wont see any amps to the battery. Make sure that the breaker is turned on and that your inline fuses on the converter output are intact.

I just noticed that you are in Wisconsin so it must be quite cold. In very cold weather, the Prius normally keeps the SOC very high. In that case, you will get very little assist from the Enginer system when in blended mode.

When the Prius is powered up and in park, the steady state current draw shown on the xgauge is about +1.2A. When you turn on a single Enginer converter, you should see -9 to -10A when the OEM pack voltage is below 230. Above that the current will be reduced. All converters are slightly different so these numbers may vary.

 

Thanks so much! I'm having one put in, I'm having an installer do it. I want to know enough to do a repair if necessary though.

COOL

 

What milage did your computer say that you got?

I just did my first drive. 23 miles at 65.5mpg. I normally get 45mpg in that car.

Thanks,
