Will Electric Vehicles Face Another Standards War?

AI Thread Summary
Electric vehicles are facing a potential standards war with at least three competing connection standards: JEVS G 105-1993, IEC 61851, and SAE J1772. JEVS is a Japanese standard developed by a consortium of Japanese automakers and Tokyo Electric Power Co., while IEC represents international standards applicable globally. SAE J1772 is primarily used in the Americas. The presence of multiple standards could lead to significant waste of resources and money as the industry navigates these competing frameworks. The discussion highlights the ongoing challenges in establishing unified standards for emerging technologies like electric vehicles.

Every time we get new technology we seem to suffer a huge amount of waste of money and resources on competing standards.

The latest to appear is the connection for Electric Vehicles.

There are (at least) three such standards

JEVS G 105-1993

IEC 61851

SAE J1772

I'm guessing SAE is in the Americas, IEC is in the EU, ... where is JEVS from?
 
Nearly.


SAC has nothing to do with the FBI, SAC = Society of Automotive Engineers (America)

Edit: should have been SAE, but it sounds better that way than stamped addressed envelope.
Thanks Berkeman - good catch.

JEVS = Japan electric vehicle standard ( a consortium of japanese auto manufacturers in consortium with Tokoyo Electric Power Co)

IEC = Intenational Electrotechnical Commision ( rest of the world)

That seems to the be common standards division (e.g. cellular): EU, US, Japan
 

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
