Hi All:

___I just received some up to date information wrt Toyota’s Hybrid - NiMH battery recycling program some might like to read. Thanks go out to Bill Kwong of Toyota Communications for the detailed information.



To ensure that hybrid batteries are returned to Toyota, each battery has a phone number on it to call for recycling information. Salvage companies that want to get a battery recycled can present it to any Toyota dealer and receive a $150 core reward.

Toyota has been recycling NiMH batteries since the RAV4 Electric Vehicle was introduced in 1998. Every part of the battery, from the precious metals to the plastic, plates, steel case and the wiring, are recycled or processed for disposal.

At the recycler, the battery modules are separated from the wire harness, controller and metal shell (all common materials that are recycled).

Using a first generation Prius battery as an example:
After the above mentioned parts are removed, there are 89 pounds of batteries.

The plates are removed from the cases leaving 11 pounds of plastic cases and 78 pounds of plates/chemicals/and absorbent materials.

The plastic cases (Polypropylene) are recycled similar to any other consumer plastic.

Of the remaining 78 pounds, we extract 32 pounds of nickel that is sold into the steel industry as an alloy to make stainless steel, four pounds of cobalt that is used in a variety of industries -- other batteries and super alloys, and five pounds of common alloy steel (terminals and intercell connectors).

The remaining materials and chemicals are processed for recycling or disposed in an environmentally friendly fashion following local, state, and federal regulations.
___Good Luck

___Wayne

Thank You. Great information to have, and directly from the source.

That's good to know, cause just like the nay-sayers said.............I'm having to get a brand new 1.3Kwh NiMH pack every three weeks or so.

Wait, I'm thinking of my gas station stops. Never mind.

$150 core - used to be $200? Oops.

I greatly appreciate that they do this, but also realize that 32 lbs. of nickel scrap has value. Surely they sell it for less than the $13/lb or so for 'fresh metal'. But not a whole lot less. Suspect that NiMH recycling does not cost Toyota a huge amount of money.

Today's dead batteries become tomorrow's kitchen sinks! The Nickel Institute has some more info on this topic.

Welcome Ken, but you are about to enter deep waters.

We have to address the dead cell first. Your next stop is Yahoo Prius_Technical_Stuff group.

The only scanner I know that completely fits the bill is Graham Davies'; built in total numbers <300 I think. Small chance you'll find one for sale. Visit his web site (ecrostech) for perhaps more hopeful info.

Add more batteries can extend EV range, after you figure out how to prevent the gas engine from starting. Paralleling batteries is harder than it sounds, and heat management must be rigorous for all the packs. This is the deep-water part.

I'll bet the other question is, "what does the replacement battery cost?"
