Chademo killed my new 2018 Leaf

By virtue of the wording "EV Supply Equipment", this term would logically be the catch all which is how I intended it. On this forum, one would think it is the politically correct term since usually if someone says "charger" they get chastised for not using EVSE.

In this particular case, I see the benefit of differentiating. So the DC units are truly chargers and therefore there is more inter-dependency and vulnerability between the charger and the car? That creates a lot of finger pointing opportunity! I didn't realize that each time I go for a level 3, I was taking that much risk.

People often come here looking for technical help. Calling one device by the name of another, different device isn't a good way to ensure that this help is effective. I know that in recent years the language in general has been tossed into the toilet, but if people can't be bothered to use the actual names for their car's major components, maybe they should just let the dealers rob them instead.

As phones get smarter, people get dumber.

"charger" is a fairly idiotic term too. The component is an AC to DC rectifier.

Err... No.

AC to DC rectifying after filtering produces a DC voltage near the peak voltage. 120VAC is 120V RMS, and about 170V peak. The battery pack needs near 400 V, and also needs the current controlled. This is what a charger does.

V(line) => rectifier => filter capacitors => charger => V(battery)

I built my first charger for rechargeable batteries (Ni-cad) back in 1975. Have you ever built a battery charger?

Err... No.

I forgot about the step up in voltage. So a rectifier and converter if AC ->DC is the first step,
or a transformer followed by rectification if the voltage change is first.

IIRC 'EVSE' stands for 'Electric Vehicle Safety Equipment.'
So the term is meant to emphasize the handshake, logic and switches. The power is not modified as it passes through the EVSE.

A ChaDemo station performs EVSE type functions with the car and in most instances AC to DC as well as a voltage change before sending the power to the car. If you use 'charger' to mean rectification and/or converter/transformer duties, then the station is a combination EVSE and charger.

To use the words of WetEV: Err... No.

[DarthPuppy]

LOL. I had originally put EV Service Equipment but decided to look up the correct translation before I posted. It is Supply Equipment.
