Float grass production line backup for example. If the main drives stopped the line would come to a halt, the glass would solidify in the furnace and it would take weeks to clear it out and back into production. So there was a massive battery backup to keep the line running.
Another application was telecom exchanges. Lots of capacity and extremely ripple voltage ripple. Technically challenging - and getting it wrong was not an option.
One that sticks in my mind was in Bermuda. Shame that it was so reliable and I never got to go there.
Ah, I wondered whether it might be something to do with railway locomotives, being you mentioned 600V. But of course, they don't use batteries (I assume) but take the current from overhead lines or rails.
Interestingly, although electricity is the most expensive domestic fuel, electric motors in locomotives (and trams) are very efficient and seem able to accelerate very quickly.
