Like the old saying goes...Time well tell. These BEV's are still in their infancy but I would imagine that the battery technology will improve in both range and reduced charge time. Sure, they may be fine for short trips around town and suburbia but I would be uncomfortable for a longer field trip just now. We also have to factor in extreme cold where the heater would be going full blast and that's when the bus is sitting when waiting for and during loading. That would certainly drink a lot of juice unless you plug it in while waiting somehow. What about road salt? Electrical systems don't like salt. Yes, I wish GREENPOWER well along with the others that build BEV's but these are all important things to consider.
