An oil company bought the patent on the nickel metal hydride battery from General motors. They have canceled the agreement to supply Mercedes motor corp. with these batteries. Reason, it seems, the Mercedes ML 450 hybrid which was scheduled for production in 2009 has to be cancelled. Read the article. Link: “Chevron drains battery planned for Mercedes ML 450 hybrid, Mercedes SUES .” In in reference to the last comment on my last article about The nickel metal hydride patent owned by the oil company the reader wrote, ”Since Chevron has owned the patent, its price has come down 75% . I would like to say this. Even if the oil companies sold the battery for the price of $1 you still couldn’t buy one if they refused to sell it to you, like they did with Mercedes. And why should they? It is not in their best interest when they are making so much profit from oil sales… READ THE ARTICLE. Our only hope is that someone gets a patent on a battery that take you further in your vehicle and they do not sell it to the oil companies. Another good article to read on Internet is: ”Chevron controls the worldwide patent rights for NIMH batteries used in the RAV4-EV,and won’t allow their use in EVs.”

GM bought control of the patent rights in 1994, part of its sabotage of the EV1.
GM fought the idea of using them, and, when Toyota brought out a superior
version in 1997, GM tried to convince Toyota not to sell the batteries.
In Dec., 1999, CARB forced GM to release 200 NiMH EV1; the other 265 were dribbled
out month by month to Aug., 2000.
In 1999, the previously non-Japanese AAMA disbanded, reconstituting itself as
the Alliance of Automobile Manufacturers (AAM), which allowed Toyota into the club.
On Oct. 10, 2000, GM handed off control of the patent rights to Texaco.
On Oct. 16, 2000, Texaco announced it was merging into Chevron (Standard Oil).
Thus, GM and Standard Oil could say they didn’t work EXACTLY together to
kill competing technologies, there was an intermediary!!
Next year, Chevron funded a lawsuit against Toyota, which used that as an excuse
to kill the EV program (perhaps as part of the deal to enter the AAM).
On May 5, 2004, the settlement agreement was announced to the public, where
Toyota was forced to pay $30 million to Chevron and its associates, and Toyota
was allowed to continue to make Prius NiMH batteries, but constrained from making
NiMH batteries large enough to plug-in.
Join TaxpayersAgainstBigOil.com to ask Toyota to resume production of the RAV4-EV
and to fight Chevron, force it to relinquish possession of the NiMH patents and
stop squatting on the best batteries ever made, the Toyota EV-95 NiMH, still powering
the Toyota RAV4-EV (last sold in Nov., 2002).
