Hymotion or enginer

From
Hymotion :: Enabling the new generation of hybrid owners to maximize their fuel efficiency

I personally don't care about plug-in kits but it seems Hymotion was WAY more reliable than Enginer. Not sure if any dealers will still install Hymotion kits, given the above.

 

BTW, I saw your other post. Why are you so interested?

Hope you realize that Gen 2 Prius isn't an EV and has a bunch of limitations that installation Enginer or Hymotion won't get around (e.g. not very very acceleration will cause ICE to turn on, if ICE gets too cold, it'll turn on, max speed in EV is ~41 mph, etc.).

OT: You might get a kick out of My Nissan Leaf Forum • View topic - Gun discussion goes here. I don't know what kubel edited out "The perplexion..." text out of his original post. It was there, originally...

 

I see. If you're looking a "payback" on your investment on plugin kit, I don't think you'll get one.

I don't care about such kits but the impression I got a year ago is that Enginer is hacky and unreliable. See Hymotion Issues? / Enginer | PriusChat. Unfortunately, my links over there point to the wrong post now after Priuschat's software changed from vBulletin to what we have now. You'll have to skim those threads instead.

For reliability, I'd go w/Hymotion instead, except that it was VERY expensive and now it's discontinued... The payback becomes even tougher or impossible w/Hymotion's price.

Honestly, if you really wanted a PHEV, you should've bought one (e.g. Volt or PiP). At least w/the PiP '12 and eAT-PZEV version of Volt, you'd also be eligible for CA HOV stickers.

Nono. I don't have a Leaf yet (long story).

I'm also cwerdna over there.

 

I agree w/ cwerdna. The Prius is not made to be a PHEV. Conversion will be frustrating, time consuming and expensive. Enjoy your 40+mpgs and be happy.

 

Speaking from my limited learning about the two products, and what I have heard and learned so far imo the conversion will not be worth it in the long run. Consider the initial investment, the payback time, and the warranty period. I doubt very seriously the conversion will pay for itself, other's will disagree with me. I seriously considered this for a long time, but I will stick with hypermiling which I just started. I am seeing 50 plus each tank without a lot of effort, simple pulse and glide and keeping air pressure at 42/40.

You can put in a EV mode button for less than buying a whole extra battery. This was standard in the Japanese and European Priuses, but was omitted in the U.S model. There is still a 42MPH cutoff point and the Engine will turn on during hard acceleration. You can buy a kit or things from radio shack.
Prius electric mode only and Prius Accessory EVMODE
I know it says 34, but I am fairly sure the cutoff point is 42MPH Feel free to contradict me

 

42MPH is what I have seen from experience, @ less than 1K RPMs.

 

The UK/EU Prius with EV switch kicks out of EV at 31 MPH indicated, no matter how steadily you accelerate.

Are there any thoughts on the Plug-In Supply company? They seem to be expensive, but I really want to get close to zero-emissions, and was not sure about choosing a company (Enginer, Plug-In Supply, etc), or doing my own upgrades. I just don't have a lot of knowledge, and worry about confidence in my DIY abilities. The High Voltage warnings scare me

 

For a GEN II (2007) please review thread PIS 4kwh PHEV kit assembly and installation odyssey | PriusChat to see if you want to proceed.

 

Thanks for your post! I scanned through it. What was the overall cost? And was 12 hours the total for the Battery Pack? Forgive me, I am studying for Nursing, and am trying to improve my family's situation being more fuel efficient and increasing my education. I will have more time to read more closely in 2 days.

 

Sorry to be the bearer of 'bad news', but if you're looking to 'save money', then a conversion system is not for you. You will NOT recoup your investment based on gas $$$ savings alone. Over the lifetime of the system you MAY get back about 1/2 what you put into it...but it depends on your driving conditions, etc.

If your objective is purely to reduce gas (i.e. imported oil) consumption, this is a good way to go. But don't expect to get back the cost of the system in gas savings alone.

What you have done so far...purchasing a Prius...is by far the best cost savings move you could make.

Plug-In-Supply has changed their pricing structure since I bought mine. I paid $5000 for the 4kwh system and another $150-$200 for misc. add-on parts and supplies (wires, digital multi-meter, etc.). You would pay more now. The time I logged in the thread for building and installing the system is fairly accurate.

In a couple of years from now, I will probably upgrade my battery capacity to about 8kwh. That will probably cost me more than if I had bought the 10kwh system in the first place. I sure wish I had had the extra $$$ at that time to get the larger version.

 

That is great that you are trying to reduce your family's footprint regarding oil consumption! I am working on a way to buy supplies directly from China. I just need to know what parts I need. I have a few connections already from an online solar flashlight, backpack, and charger business. I would like to completely remove myself from the power grid, but that will be a future endeavor. Right now I am going through school, but working on upgrading my Prius battery run time, during my breaks from studying.

Anyways, I am trying to figure out the best, longest-lasting battery cells. Then will have to put the system together. I hope to pay wholesale for the whole system, batteries first? That is my goal anyways. If I can successfully round up the parts, then the 8kwh system you might buy would be reachable at around 50% less.
