An electric bus that drove 1,100 miles between charges...

Very interesting!
But at 50A it would take a lot longer than just overnight to fully charge 660Kwh battery pack.

We may not live long enough to see these things in full production, but it is exciting!

Toyota has announced that they are coming out in 2020 a solid state battery that will propel a car 400 miles and with can be charged in 10 minutes. That would probably need to be hit with 650 Kwh.

Yea more like three days. Maybe longer if using/charging electric toad daily. ;)

That is so cool!

Maybe a back-up low emission diesel generator could be used on board if needed to run air conditioning and recharge batteries at only 3/4-1.0 gallon an hour.

Safe travels,

shreveport is running all electric busses next year they have 3 in service now

Proterra's high-voltage overhead charging system uses robotic control (and some autonomous software on the bus) to replenish bus batteries in as little as 10 minutes, depending on the size of the battery pack. Charging at 250-1000V (DC) and up to 1400A, the system is eight times faster than the CHAdeMO fast-charging standard and between three and four times faster than Tesla's Superchargers. And unlike the old-fashioned pantograph, which needs to cover the vehicle's entire route, Proterra's system is static. This means bus operators can install them in terminals or at the same locations they use to refill their diesel tanks.

"The interesting thing is these diesel buses have such massive fuel tanks—given how inefficient they are—that it takes longer to completely refill an 80- or 120-gallon diesel bus system than it does to recharge our electric vehicles," explains Proterra CEO Ryan Popple. "So we're actually getting to the point where the vehicles that are configured for fast charge can be replenished faster than you can stick a hose in the side of a diesel bus and fill it with fuel."

According to Popple, Proterra's fast-charger can recharge a 100kWh electric bus in just ten minutes, sufficient for a circulator bus route of 30 (48km) miles or less. That's better than diesel or even natural gas, he told us: "We've gone from something that would have been considered a negative for EVs—slow overnight charging—and now we've gone to the point where EVs are advantaged relative to combustion in terms of speed and ease of refueling." (Recharging the 400kWh batteries of a longer-range electric bus would obviously take longer.)

Like the electric cars, but probably much worse, is the cost of the battery replacement when it is needed.
Some of the various automobile's value are depreciated based on the projected life remaining with the batteries. Apparently at that time, the cost to replace the batteries, and dispose of the old batteries, exceeds the value of the automobile.
Batteries are getting better, but they are also getting more expensive.
