>EVSE is not a charger. Just a way to get 208/240 V to the car - and the onboard charger.

not according to the new 2024 IECC. I'm not saying you're wrong, I'm just saying that's not how they look at it.

Terminology. A charger is something that converts AC correct to DC current so the (DC) battery can be charged under controlled conditions. The EVSE neither is or does anything of the above. But people still call them ‘chargers’. Better would be ‘charge connection’, charge station, connection station, etc. More about educating the public in baby steps. Also so the consumer doesn’t buy more than what is ‘needed’. Many EVSE have added intelligence (for timed charging, to measure kWh, etc), intelligence that’s also present in the vehicle.

exactly, it's terminology. And the only terminology that matters, from code perspective, is what is defined in the code. Again, I am not arguing you're technical view here. I'm just saying it kind of doesn't matter. The question is about code. What you feel is right or wrong based on engineering principles is irrelevant.

Don’t disagree, but we don’t call a pickup truck a bus, just because it also happens to have 4 wheels 😉

there's volumes of stuff in the code I disagree with, especially the new IECC with all the new EV stuff. It's so wrong sometimes, I don't know whether to laugh or cry. But at least the intent is good. And they aren't fucking it up so bad with anything more than their definitions.

I'm honest, and in the cell phone situation, we know it is actually a charger (115/240 VAC in, 5 VDC (in most cases) out. You can take in anywhere.

In the car scenario, you supply mains to the car (unless a SuperCharger/Fast charger when you actually do supply a DC voltage) and the 'charger' sits on board. One reason that in most cases, you cannot take a US spec car and 'connect it'/charge it in Europe, etc. The 'charger' is very specific to the market.

This might be a bit geeky, but I like the way this guy explains it:

I don't expect to 'win the battle' but I do like to educate people on what it is. EVSE is not a charger :-)

And maybe as a poor analogy; we expect drivers to know the difference between a gasoline and a diesel engine (as it’s sort of important). Hopefully we can get drivers to know the difference between an EVSE and a charger as well.

Happy New Year!
