Personally I am very exited about it but we lack data that does allow us to do proper TCO comparison of ICE vs EV on the heavy duty side. Also how does V2G economics actually work if you are trying to optimize for the lowest charging rate (usually during night to avoid peak)? If you are in V2G mode after 6 pm i assume you would need to start charging at night during cheapest rates and assure that the bus is charged by 5 am. Wouldn't this require 1 to 1 charger to bus ratio as you might not have enough time to swap? Wouldn't then infrastructure costs(chargers that are build and concrete around it) skyrocket?

- ilikeatari 5y agoYes, makes sense from the districts perspective, but I meant from sustainability of the business model perspective.
- sokoloff 5y agoAny overnight charging solution almost surely needs a 1-to-1 ratio anyway, because you're probably not going to pay an expensive and unreliable human to plug and unplug buses overnight every night when a charger will last 10+ years. You're already paying the bus driver to park the bus and to drive it away in the morning. Add a minute of bus driver labor to plug it in and a minute to unplug it in the morning.
