Ideas for soft encouragement of 85% charge.

[Grease Lightning]

because mot chargers bill by energy delivered it encourages the charger company to kick off slow charging cars, or cars that are past peak charging rate

This could be fixed if they charge an additional “per minute” fee to normalize the amount of money they could be getting, plus deters those that just wanna.

As I said before, all of the stations need some 48 amp evse so people can move over to once they hit the 90-95% crawl. That allows for them to implement a cap (90% not 80%) and still allow people that really need a deep charge the option.

Then put very hard limitations on charging above 85% at DCFC.

I would suggest 90% as a lot of cars still fast charge above the allowable under a/c, but have long suggested the same.

There is good reason, and your own arguments made it at times. All car have a different curve. So you only have two options a kW or a % option to cut off if there were level 2 evses onsite. While I have advocated for a 20 kW bench, percentage may be the most universal for the end user.

The reality is the 90% makes sense from battery protection, sales targets, and convenience.

As others have said, the need to deep charge will go down as more stations come on line.

The other option to your point would be to include some 50-70 kWh DCFC on site for the slower chargers and those that hit that magic cap whatever they decide.

All I know is 80-85 is too low, and I will not be “educating” people as some on here want to.

You want people to take up a spot for 10 mins. while waiting to continue to charge 85 to 100???????
NAH! If I was waiting in line that would piss me off.

Sounds like you need to start your own charging company so you can set the limits you want.

I work in regulation, you have to set these “arbitrary numbers” to a data point that is around the tipping point. Unfortunately it sounds like when this becomes industry standard you will be disappointed because it will be an arbitrary number that works for the majority, not the minority. ?‍

You need to read people’s posts, I never said anything about that. Now you are just making up stuff.

Heck just make charging like buying fuel. Low octane cost this much, Mid grade cost this much more, and premium grade cost the highest. Different charge rates based on vehicle percentage.

I hate this idea so much. And most of them in this thread.


Imagine the news getting word that charging to 100% cost more than to 80%.



Everyone situation is unique and every trip is unique. These solutions could seriously impact people.

If any limit were to be put into place before a surcharge, it should be 90%, at least initially. I've had more than a few stops where I needed more than 80%, but only a handful where I needed more than 90%, and with new locations added, those are likely not necessary any longer.

No, that would not work. They would have to be forced to move to the back of the line.
