"Osborne said three of the seven buses needed complete battery replacements within the first five years, and in one case a battery started malfunctioning after just two years.
“The battery replacements on our three BYD buses each took 80 days to accomplish and were out of service for the duration of the replacement,” Osborne said, adding that the city has also experienced issues with the BYD-made bus chargers as well, noting that the chargers started failing after less than two years of use.
“All seven BYD buses have received full propulsion component changes — including the drive motors, reduction gearboxes and hubs," as well, Osborne explained.
“We have also had a fleet-wide replacement of compressors and high voltage junction boxes, as well as numerous power inverters, modules, coolers and oil pumps.”
"In 2017 the city estimated that the electric fleet would be able to drive about 233 kilometres a day in the summer months, but Osborne said the electric busses only average about 110 kilometres a day in the winter months, whereas a regular diesel bus can travel 420 kilometres a day."

Why does an electric bus need an oil pump?
I thought one of the selling features of electric vehicles that they are so much simpler.
I suppose this might be an oil pump for the air compressor?
Do they just use air compressors off of any other truck for bus? They also have a dedicated coolant system for the air compressor?

Electric streetcars are still used widely in Europe along with commuter trains and subways. All electric.
Hydrogen will be used for heavy vehicles like independent buses and trucks.
Toronto still has a downtown core of electric streetcars that handle a lot of passengers.
The future is electric. Are you still using a ratchet and compressed air impact wrench?

What does a streetcar/electric train/subway have to do with battery powered buses?
Unfortunately, most western cities tore out their overhead infrastructure that powered the streetcars and trolley buses.
Imagine explaining to someone from a century ago that we would give up that proven reliable system with virtually unlimited range, that worked in all weather and climates; to battery powered buses. A giant step backwards.
