RE:All of a sudden
You Know, that Toyota has been building a battery plant in North Carolina for over a year now. The thing is, they have never said who's battery cell thet were going to produce. They certainly do not have one of their own. Battery plants have a lot of infrastructure in commom so it is possible to start construction without having the final cell decided on. Toyota already knowns what the Electrovaya cell production process will be because Bastain Solutions is doing the automation for the pilot production line now under construction in Mississaugua.
You know Toyota has had the Electrovaya SS cell to test for a while. They probably even have a prototype battery pack.
