Electric car chargers aren't chargers at all – EVSE Explained

THERE HAS BEEN SOME NEWS - There's a pinned comment you might want to read. But there's some links down here, too.

Firstly and of supreme importance, the video on the Bolt's Bits from Weber Auto - Prof. John Kelly is amazing and you really ought to give that channel a look if you're interested at all in hybrid and EV tech;

Then my usual ones;
Technology Connextras (the second channel that stuff goes on sometimes):
Technology Connections on Twitter:
The TC Subreddit

THERE HAS BEEN SOME NEWS. Tesla won the plug war. I made a video which you can watch.
Most of the info in this video remains correct (the technology is pretty basic, after all), but a different plug will almost certainly be on the end of the cable in the future.

"A contactor is simply an electromagnetic switch."

Oh relay?

[definitelynotobama]

How on earth does this man consistently make 40 minute videos that I am perfectly willing to watch through completely?

[Roxasedge]

"Integrity of the protected earth" is the most mystical sounding thing I've ever heard you say

[bwizz]

As an embedded software engineer in the automotive space who works for an EV company, this was a pretty good explanation. Well done!

[BRUXXUS]

I propose the charging standard be called HDCC: Handy Dandy Car Charger

[ttd]

"Let's not get any more pedantic than this video is already guaranteed to be" - that's why I love this channel

[devinholland]

The standard is also being added to golf carts, they use lead acid batteries so may require ventilation.

As an EE with over 30 yrs experience and 2nd Tesla owner, I must commend you on an outstanding explanation of EVSEs. So good that I was compelled to subscribe. I think some of the vendors make their unit big to justify a high price. The same technology is in mobile chargers which are considerably smaller.

“Not a lot really!”... looks at timestamp: 27 minutes. This gonna be juicy!

[MrPiki-xmzo]

I'm waiting for USB-C charging electric cars.

[kking]

I love this channel because this guy has an intelligent sense of humor, and explains things in terms without making the viewer feel stupid while learning. And he’s a smart ass too, lol. The sheer amount of sarcasm he displays is entertaining in itself.

[jazzdirt]

"This is not a drill" shirt hitting the nail on the head...

[kemt]

Awesome video, as usual. A comment on the ventilation thing: I had a unit similar to this one in an aircraft hangar, used to charge the batteries on an electric tug. They were lead acid and, like you mentioned, required some ventilation while charging.

[Legolas]

"I'm designed for 10, 000 insertion and removal events" is a solid pickup line.

[Spartan_Jackal]

"What are contactors? You'll find out *shortly*"

You're getting ejected.

[mandisaplaylist]

12:40 Exactly. Specifically, this is used in industrial settings where lead-acid battery powered equipment is pretty common (because in industrial settings user convenience is not that important than in electric vehicles). I believe this is an effort to standardize electric vehicle charging across these very diverse applications.

Additionally in these industrial applications there may be other types of batteries who need to do wacky things when being charged. Like some batteries that need to shed quite a bit of heat and stuff like that.

There is a reason why it is so expensive: It's branded "Siemens".

In the next episode: Why Type 2 is superior to Type 1 ...

[mikeselectricstuff]

The additional function of the PP pin is to tell the car the current rating of the cable itself

[nsayer]

“An Arduino, a contactor and a willing middle schooler.”

I refer you to OpenEVSE, which is perhaps slightly more upscale than hiring a middle-schooler. 😁
