Battery Isolation Switch

[Greenmantle]

Have a Mercedes BEV and I was wondering if it has a Battery Isolation Switch (High Voltage). Some one on here showed the one for a BMW i3 and it got me thinking.

Not a switch as such but there will be a main service disconnect aka MSD.

If you Google the emergency responder guide for the model you'll probably find where it is.

Not something you should go disconnecting for the fun of it though.

Indeed - there are some switches that it's best the casual user don't get to switch!

I don't really understand why the ability to do so would be desirable for the driver anyway? The only EV related dangers we have seen which are related to the electrical system are battery faults - thermal runaway, which takes place ahead of such a switch and will continue regardless of what is disconnected.

Having said that... I'm reminded of the early days of EV where a few drivers claimed their car was 'uncontrollably accelerating', but it turned out they were trying to dodge speeding tickets by making up phantom acceleration
