Teaser for the weekly build 8
You will not find many obvious changes this week’s release. We’ve taken a small step back from the rather crazy development cycle and the rest of our efforts have been focussed on fixing issues.
It seems we’ve been pushing the ELM a bit too hard; CanZE appears to freeze now and then, though it is usually the communication between the CanZE and the ELM. Please know it has our full attention, but it’s a hard one to crack as it’s really a bit of a random issue. We believe we’ve made some improvements though. Keep us updated (through github please!) and send us your logs please as it helps is pinning down what’s going on.
We’ve split the “Experimental” section into “Experimental” and “Technical”. Technical contains screens that should work, but are for the users that want to dig a bit deeper. At the same time, we’re cleaning up the “Main” activities to only display the information that matters most.
The Cell Voltages Heatmap has a new function that you should actually never see: if a cell turns bright red, it means it has a serious problem. The algorithm used is borrowed from Nissan: If the delta between the mean and lowest cell voltage is greater than then 1.5 times the delta between the mean and the highest cell voltage, it is considered bad. This check is only valid (and will only be performed) if the pack’s SOC is roughly 25% or lower.
EDIT: I was not aware that the Leaf uses a different chemistry for the battery than the Zoe. The red cell algorithm used may, or may not be valid. Don’t rely on it.
Here is a (faked) example
Have a great remainder of your weekend!
