Texaco sued them for $30 million (and won) for using that battery after they had bought the patent to it. That is why they made the Prius and had to have a gas engine on it to charge the smaller batteries.
Edit: from wikipedia: Whether or not Toyota wanted to continue production, it was unlikely to be able to do so, because the EV-95 battery was no longer available. Chevron had inherited control of the worldwide patent rights for the NiMH EV-95 battery when it merged with Texaco, which had purchased them from General Motors. Chevron's unit won a $30,000,000 settlement from Toyota and Panasonic, and the production line for the large NiMH batteries was closed down and dismantled. Only smaller NiMH batteries, incapable of powering an electric vehicle or plugging in, are currently allowed by Chevron-Texaco.
It appears Tesla was just ingenuitive enough to make a design to get around the patents locked up by oil companies- by using thousands of small batteries.
One of these days I'm going to watch it: Who Killed the Electric Car? |
That's really messed up that those companies get in the way. Of course they have their own immediate interests in mind, but what about our future generations?
I've been recommended that movie as well.
