What is

[Johann Koeber]

I am relatively new to EVs and I am not an engineer. Rather I am an accountant.

I love all the tech talk here, but much of it I can't understand.

Why not have a place to post questions beginners might ask - and answers.

What is a PEM.

My research led me to Wikipedia

PEM may stand for:

• Peabody Essex Museum
• Pediatric emergency medicine
• Photoelastic modulator
• Polioencephalomalacia
• Polyelectrolyte multilayer
• Porous European Mix – a type of asphalt used on roads and airport runways, commonly referred to as PEM
• Portable Emissions Measurement System (PEMS)
• Predictive Emission Monitoring System (PEMS)
• Positron emission mammography
• Privacy Enhanced Mail
  
  • the .pem filename extension is used for a Base64-encoded X.509 certificate
  
  
• Protein-energy malnutrition
• Proton exchange membrane or Polymer Electrolyte Membrane – as in "fuel cell", applications include use in proton-exchange fuel cells, used to manipulate hydrogen for energy conversion
• The IATA code for the Padre Aldamiz International Airport in Puerto Maldonado, Madre de Dios, Peru
• Pemberton railway station, England; National Rail station code PEM
• Puritanical Euphoric Misanthropia
• PEM nut Self Clinching nut - commonly referred to as 'PEM'

All I gathered from other posts was that it was black and pretty expensive.
Am I dumb? Please educate me.

Thanks

Hi Johann, and welcome! Thanks for trying to find the answer on your own first, that's appreciated. I've found that if I add 'electric car' or 'EV' to the word I'm searching on, I have more targeted results. Try this link: HowStuffWorks

There is also a spot here on the forum where some of the basics are explained: Tesla Motors Club - Enthusiasts & Owners Forum FAQ Pretty soon you'll be the one answering questions .
