I stumbled across a manual intended for the emergency services etc who
might encounter hybrid vehicles. I was surprised that the vehicle in
question (and I expect others) have a drain facility on the drive battery
to permit the draining of (presumably flood) water, along with procedures
to follow. While Im aware Lithium and water isnt a good mix, Id have
thought if the battery was flooded and anything bad was going to happen it
would have happened before anyone had a chance to drain it.


I saw mention online of somebody try to rescue a drowned Tesla.
Apparently, one of the cells exploded when he tried opening the battery
pack in order to dry it out. Whether that would have been the case had
he been able to drain it first is unclear.


Im not sure.

If the water can get in, the pack cant be water tight. Perhaps the action
of opening it weakened the structure.

I cant help thinking the battery would be scrap once flooded.
