It's darn close right out of the box - my experience has been within 2-3% of actual charge so far.

Also, you actually can modify the EVSE charge efficiency percentage through the app which can dial in the charge % accuracy even closer.

For a Leaf S owner like me, the most valuable thing I find about the Juicebox is that I get the remote app charging features of the higher end SV/SL trims even on my Leaf S. That's worth a lot. Very happy with mine!

You have to set the starting percentage every time....which takes no time.
Thanks for the screenshot.

It's not surprising that it's so-so. All Juicebox's software can do is make an educated guess as to how many kWh should be dispensed to reach a certain dash % SoC. There's nothing in the J1772 protocol for the vehicle to tell the EVSE the attached vehicle's state of charge.

Unless you can make corrections/teach it, will be further and further off as the battery degrades.

Well that’s kinda cool. How do you modify the charge efficiency. I didn’t see it.

If you go into the app, under vehicle settings there's a parameter called EVSE Efficiency. For the Leaf I believe it's set for 92% by default but you can adjust it up or down as needed.

Also, you should check out their dashboard on the web as well if you haven't already. A lot of the same functionality as their app plus some cool reports and stuff.

Found it. Yudaman Nrvus. I checked the smart setting. It’s also 92 percent. Now to fiddle...obsessively.

I’ve used the web interface. Nice.

The easiest way I've found so far in my 2019 Leaf is to look at the charge time screen. It shows how many hours to get to 75%. Then you just set your timer for that many hours or slightly above. Works well if you have a regular commute.
