Emergency disconnect device
This problem is approached in a different way by car manufacturers and electricians:
• vehicle manufacturers do not consider emergency switches as a necessity and want to avoid them (they are in fact not present on thermal vehicles)
• electrical manufacturers consider emergency switches as essential (they are in fact
present on any industrial electric device)
Emergency switches come in different versions:
• battery connectors
• direct-acting emergency buttons
• indirect-acting emergency buttons
It is recommendable that the disconnect action is direct.
Furthermore, its operation shall not be detrimental to the controller.
