Do You CAN?

It ought to be all over the place. CANbus is about 30 years old.

it is but the average shade-tree mechanic has no idea its right under their nose. I never learned of it until I dug into how Tesla charges its batteries. I wanted to know how the car knew how to accept the range of voltages it accepts from the same charging port. it will except from 110VAC all the way to 500(actually 480)VDC when using a Chademo charging adapter

You fell for the common misconception that the SAE J1772EV charging station plug puts DC into the battery. Actually the charging station electronics monitor the AC source, connection to the vehicle for voltage, current and provide ground fault protection for the user via a data link between the units; all the DC conversion and control of the charging process takes place inside the vehicle.

actually I did not. I didn't learn about Can Bus until I was researching DC fast charging. the car can direct DC directly to the batteries and bypass the onboard charger(s) if the Can Message asks the car nicely to open the door to the battery pack.

I did not get that impression from what he wrote......

According to Wikipedia CAN is also available on bicycles for controlling mountain bike shifters!

Some history: Hughes Aircraft Company actually looked into the potentials of using CAN-bus in some of their missiles in an attempt to standardize communication protocols amongst their many different USAF, USN, foreign, missile products.

...and the Process Control industry uses it under the name Fieldbus.

Thank you, now I understand what everyone is talking about

I CAN!

For vehicle networking CAN is today's standard, but as vehicles get more complicated there is a movement to replace it with twisted-pair Ethernet.
