This is interesting, there are several clues, American company with a range of electro-mobility products, fortune 1000 company, specialty subsector in electric-mobility and replaces diesel or lead acid powered products. The only thing that comes to me is mining equipment (Caterpillar?). Here is an example, not Caterpillar but the same sector. http://www.mining.com/battery-powered-mining-equipment-is-a-lot-cooler-underground-compared-to-diesel/ What other sector has a range of products powered by either diesel or lead-acid? And it has to be a new product for Electrovaya, they are already working on trucks/buses so that would not be a new product for them. I would assume it has some complexity to the system to warant hiring all the engineers etc.
