The company that my son works for, builds diesel/battery/electric trolly & free running municipal buses...
the Batteries feed an inverter that outputs 770 volts DC, which is used to drive the electric motor that actually moves the bus. The diesel engine is just a backup in case the bus is "off grid" for too long ( ie, traffic accident ) so that they do not have to have it towed back to the grid.
The Cold Weather testing, IIRC, was done up north of Saskatoon and the temps there were -59° most of the time.
Those batteries are humongous, the same size as the Telephone Equipment batteries I used to take care of.... 2 volt cells measuring at least 12" thick, 30" or more in depth, and about 36" tall? been a couple of decades+ since I have seen them.
those batteries are being replaced with a new Lithium technology type battery, lots more power, in a smaller space.
