App note from Vishay on how optocouplers play a role on safety for Electric vehicles. Link here (PDF)

The number of electric vehicles on the roads is steadily growing, increasing the need for safe and reliable battery systems and high efficiency battery chargers. Modern electric vehicles use battery systems with voltages up to 1000 V and charge times down to a few hours.
