Myths Regarding Electric Vehicles- Myth #2 is Shocking!

(Rick Sanders, CEO, Tuesday, September 24, 2019)

One surprisingly and prevalent myth regarding electric vehicles is that you cannot get your electric vehicle wet. You cannot drive in the rain and must plan all driving around the weather forecast. You cannot even go to a car wash! Okay, while it is true that you cannot drive your electric vehicle in lakes or the ocean (yet!), you can get your electric vehicle wet- whether from inclement weather or to revise its shine at the car wash.

It is quite shocking, but 18% of drivers believe that you cannot take your electric vehicle in a car wash.

HowStuffWorks tackled the question, “Will I get shocked if I drive an electric car through a big puddle?” Here is an excerpt from their comprehensive analysis:

To understand why water doesn’t bother the batteries or the motor in an electric car, first consider the fact that every car you’ve ever driven has had an electrical system. It operated at much lower voltages, used a different kind of battery and served a different purpose from the system in a hybrid car, but the principle is the same. All cars have batteries and electric systems, yet they don’t short out or shock anyone in the rain. Even if you get water on the battery terminals, it generally just causes corrosion, not an immediate catastrophic effect. In fact, in several models, notably certain Chrysler vehicles, the 12-volt battery is mounted behind the front tire, near the bottom of the car, where it is frequently exposed to water and other road debris.

To dispel concerns, Elon Musk demonstrated how the Telsa Model S “floats well enough to turn it into a boat for short periods of time” while driving it through a flooded tunnel in Kazakhstan.

Vadakkus provides a great summary:

Those who claim EVs cannot drive through waterlogged roads or heavy rain while fossils can, do not know anything about water or vehicles in general. I have heard people say car motors will “short out” in the rain. Hilarious. Dude, we conquered that problem like a hundred years ago. Ever heard of submersible pumps? Hell, if that was the case, the entire Indian Railway network would come to a sizzling halt at the first drizzle! In fact, with basic waterproofing (which is standard, of course), electric cars can tackle waterlogging much better than fossils. They can run up to their pillars in water because EVs do not need to breathe! Petrol and diesel cars need an uninterrupted supply of air into their engines to burn their fuel, and once water gets into your air filter. Once the water goes above gearbox level, you are in trouble. With electrics, the only thing you will have to worry about is getting your feet wet.

Basically, electric vehicles are workable for more than just the sunshine states though we don’t necessarily recommend driving yours in Southern California in the rain- because you will be shocked, not by the car, but by how people here freak out when it rains.

At Rhombus, we design and develop advanced systems for medium/heavy duty (M/HD) EV charging, power conversion and energy management. We deliver highly efficient, custom solutions and robust products for integrating energy storage and renewable sources for commercial and industrial applications.
