hogey,  In reading the article you linked about that BAE Systems Drive for the Nova Bus.  I noticed that the battery size was 594 KWH.  Since Electrovaya makes a 300KWH and 700KWH battery, it does not look like the Electrovaya battery is in this Nova Bus model.  The 300KWH battery that was shipped must be for a smaller bus model also in the works?
