EV drawbacks

Can Gov Murph tell me what to do with my EV when the tide comes up and I have to drive through 12-18 inches of salt water ?

This is at Rufford Ford in Nottinghamshire, a place that regularly floods. There are numerous videos of vehicles driving into the water and getting stuck in the middle. The Tesla got through OK;

They made Eveready Dolphin waterproof torches in the 70's so nothing groundbreaking there.
Still would not convince me to get one.
Scandinavian ferries have not banned IC engined vehicles - for a reason. EVs?

Sod that in an electric car!
You only need to look what happened in Florida in the floods

Agree, but it would seem that it is possible - presumably if the battery and motors are sufficiently waterproof to withstand driving on wet roads, then driving through the ford isnt a problem. Wouldnt make a habit of it though..

As baz recognized above , is this salt water ? I live at the seashore and have to deal with fording salt water on a regular basis . Automobiles in my region rust away long before mileage gets
them .
 
Obviously, the main issue when driving an ICE vehicle through water is it sucking in a load of water into the intake.

An EV doesn’t have this risk, so all good there.

But, moisture ingress into the battery cells is what causes these things to combust in their unstoppable way. So it’s hardly what you’d call risk free !

True enough Nigel - but the intake system is generally much higher than the batteries in an EV . Where I live a Tesla’s $ 20 k battery has the potential to be completely immersed in salt water several times a year .

All ev battery assemblies have venting ports to allow for gasses to escape and for cooling/pressure equalization.
There is also a risk of an electrical connection leaking, leading to a short and potentially the thermal run away situation.

You sure?

My understanding is they’re sealed and impervious to moisture by necessity …
 
Would any of you consider flying down the highway at 70+ mph with your family in the car and entrusting their lives to an on board computer?
Didn't think so.

Well I certainly wouldn’t - but sadly there are some that would.
A few years back there was a commercial airline crash on approach to landing killing all onboard IIRC. Turns out there was a problem with the automated landing system so the crew were manual flying the aircraft. The problem with that was no one in the cockpit had ever actually manually landed an aircraft - WTF ! How the hell did this come to be ?

I wouldn't
But then I'm old,I suspect there are many out there that would trust that level of technology
Sadly

Sealed, yes, but have vent ports with membranes meant to exclude dirt and moisture.
These can fail or be faulty out the box.
