The OEM they have the deal with is a battery company (as stated in the announcement) that assembles battery packs for electric buses among other things. As I posted before I believe it is with BMZ of Germany who has plants in Europe as well as China. In some of their presentations Electrovaya posted among their pictures a bus from ebe-Europa. BMZ supplies the batteries for ebe-Europa, I think there is a good chance they are working together. I don't know of any other battery manufacturer that fits the profile. Sankar said they are working with multiple bus companies and I believe Volvo is one of them. It would be nice if the 5th customer they have signed turned out to be Volvo.
