Cool. Thanks for the reality check. Blue Bird will have two battery sizes: 100kWh and 160kWh. So for some of the shorter routes the smaller pack could save money. If a bus is going 45 miles in morning and 45 in the afternoon, 100kWh with two charging cycles could be more than enough.For our local school district these fuel savings are a bit high. We’re running route busses about 60 to 90 miles per day burning 7 to 10 gallons a day average. So average annual consumption is going to be less than 2000 gallons. On the other hand commercial electric rates are just over $0.05/kWh. We have very high demand charges but these only occur between noon and 8 pm so could be entirely avoided in this situation. Some of our shorter activity trips could also be covered while longer trips would still need to use our diesel fleet at this point.
The vehicle to grid capability could be very interesting as an additional revenue stream for a school district. These busses are parked for the vast majority of the summer when they could be helping with peak loads.
