Toyota Prius Replacement Battery Problem

Are you serious?

How did you ever get into business?

You have no technical staff?

Who does your marketing work?

I'm having serous problems believing you are s real business.

Does your business have a name?

Tax license?

Incorporated?

This sounded rather dodgy to me so I did a little research (it sounded to me like you may be supplying counterfeit and potentially unsafe batteries to undercut the approved suppliers and reputable aftermarket battery re-conditioners).

Before we go any further what do the local laws say about what you are doing?

Have your batteries and integrated safety electronics been tested to the applicable automotive battery standards?

Is this actually legal and if so are you meeting all the legal and safety requirements?

Our workshop is in New York.

That may be the most surprising thing you have said, I take it the batteries and associated safety electronics are being sourced from China thou (from a reputable quality supplier I hope?).

A lot of background questions have been asked first as what you are doing (if you are not qualified to do it or are trying to sell cheap sub-standard parts) could potentially put a lot of people at risk and hence raises a large ethical (and potential legal) issues for myself and likely others on this site if we offer any advise to you if you are in fact one of the dodgy aftermarket battery suppliers.

Can you supply a link to your company website and battery suppliers for clarification?

No doubt you may have worried about it.

As I have said, we have worked on Honda Insight Hybrid car replacement battery for several years using such batteries.

If you have some contact this after market, you may heard of the name Ron Hansen who first use my battery in the after market few years ago. I can show you several companies who continue to buy batteries from me, if you give me your e-mail.

In fact, Ron still work with me for this project, and he is in New York. He still have one pack of such battery in hand, and need some electronic or computer guy to accompany with us.

Is that Ron Hansen, Former President of Hybrid-Battery.com?

Do you have a company website?

Yes, that is him.

This is probably somebody servicing cabs in NY, they use the Prius and are over the 10 year 150k warranty period....The battery packs are available on Ebay for around $1k out of wrecked vehicles, and around $2300 + $1k installation from dealer...The batteries have been proven to last beyond 200k miles so far....that is of course if they are properly maintained....

OK, fact tell ture. If anyone serious, I can send one battery stick to them, in my cost, provide that he will test its quality and tell people here. And he know how to test of course. Prius 1st generation use same design, and it is now using in Honda Insight.

I have few agents for Honda Insight hybrid car battery after market in USA. I am not so open because to protect the profit of my agents. I don't sell to end users.

I just want to enter Prius market because it is much bigger market size, but of course, it is not easy. Need professional to partner for benefit together.

I am serious.

Sooo, you are actually after a business partner not technical advice?

We are jammed at technical barrier, I myself and Ron unable to solve it.

I hope one guy who can partner with Ron in USA to solve the real problem and together enter the market and share profit together.

There are battery rebuilders like re-involt...$1875. plus shipping and old battery, which is worth $200 from dealer.....I don't see any savings....

David Taylor buy battery from me much lower than $1875.

Oh, sorry, David bought from me for Honda only.

I don't realize he make Prius battery as well.

That is from somebody else.

Why are you posting anonymously? You shouild be proudly standing forward - if you are for real...

OK I am not familiar with the forum system, may be I in mistake tick the "anonymously" for it.

Anyway, pls don't be negative on me, I don't get money from you guys. I agree this plan is not easy, may be fail, but who know if you don't try, and if you have interested, time and know how, just contact me. We are very small company and have very little budget on it.

I don't think shape is what is changing voltage/current curve, it must be technical differences in chemistry, electrodes materials and prep, dielectric etc. Now the battery management system is programmed to inteprete differences (even enhancements) into possible errors. Instead to try to adjust your batts to what's expected by the system, try to get info on how the expected curve is programmed. Now I wouldn't be too hopefull, because those that developed it (and remember, it's new grounds and money is BIG for that) wants to get his money back, and not only that, he wants to have money coming untill someone comes up with something better.

P.S. Being serious about making battery packs, involves cell celection and strict matching, OR ELSE... SM.

I would go first for a re-programming of the car's electronics to suit the new battery type.

In the long term that would be best and it could also be "returnable" to original spec if needed.

You maybe able to add a menu in some processor in the car and switch between battery types/curves.

If that does not work, you need to build some sort of "interpreter" that "translates" the new battery curve into one that fools the car's electronics into thinking that the original battery is still in place.....a small PIC or other processor could be used....you will need to somehow observe how the standard battery is checked and simulate that...

Best of luck.

Thanks folks,

It sounds not easy task. Will update more information later.

Sounds like the folks Fiskar bought the batteries for his Karma electric fiasco from.
