They are literately only good for about 3 years, and depending on how aggressively you charge it, you may wear it down to 75% capacity within the first year.
Current EV's are only warranted for 5 years or 125,000 miles, except for Tesla which the higher-end models are unlimited.
This is what you want, is a unlimited warranty on the battery for an EV, because that removes the risk of the battery failing before the vehicle life expires. A EV bus would need to last at least as long as a regular bus ( roughly 10-12 years in the US
http://ntl.bts.gov/lib/44000/44200/44244/Bus_Lifecycle_Cost_Model_User_s_Guide.pdf , with the warranty on most parts expiring at 7 years.)
Of note, Diesel buses only get 4 MPG, so just about any alternative is worth considering.

The track would be energized, the dog is far more likely to risk electrocution if the trains are running because the dog can't just jump to the platform height. The trains would have only automatically stopped if the dog was in the track area of the station.
I'm not sure if there was a possible happy ending to this story even if everything could be done short of someone with a tranquilizer 🞵🞵🞵 shooting the dog so the dog would be immobilized. You know eventually what was going to happen, even if the trains were stopped and track de-energized is that the dog would have had a heart attack from being chased and cornered by strangers, or the dog may even turn around and attack someone. I'm sure this isn't the first time an animal has entered the track area, and if you think about it, there are multiple points on the guideway where (eg where it goes between grades) where an animal might be able to jump into the guideway and not get out again.
What bothers me is that whoever had responsibility for trying to get the dog out, seemed to not have enough agency to get the trains to stop and stay stopped. What if it was a child?
If this was a surface LRT, we'd never hear about dogs or children on the tracks, because the driver would never get a chance to react, we'd just hear about a delay and no specifics to not make the media go on a witch hunt. Trains do not stop on a dime, and neither do cars.
