nice but so used to it the charge/discharge being displayed the other way
I am following Nissan's convention where current into the battery is positive and drain is always negative. Think of it as your bank account. Positive entries are good.DaveinOlyWA said:nice but so used to it the charge/discharge being displayed the other way

TomT said:Agreed. I have never seen a charging system display that did not show current in the battery as negative and current out of the battery as positive...

That dash is showing Motor power not battery. So to the right is power to the Motor and left is power from the motor.QueenBee said:TomT said:Agreed. I have never seen a charging system display that did not show current in the battery as negative and current out of the battery as positive...

Even the LEAFs dash shows positive (to the right) for energy out of the battery and negative (to the left) for regen into the battery.
Alt Gids were dropped as it was not supported on the newer Leafs. When reading Alt Gids the battery AMPs value was also included in the data the Leaf returned so I got it for free.vegastar said:I just bought Leaf Spy Pro and don't know how to enable battery AMPs as in Leaf battery. In Leaf Battery to see the BAT Amps I had to select Alt Gids in the configuration but that option is not available anymore. Is there anyway to see BAT Amps and not the motor rpm?
I am showing the 12v battery amps as I get it from the Leaf in the format the Leaf is sending. I am not deciding on a polarity. It comes that way and that is what I am going to display.garygid said:With the GID-Meter, I show the Battery Pack outputs, both voltage and current,
as positive.
With only four digits to use, and output currents over 99.9 amps
possible in normal operation, then 123.4 amps output is consistant with
392.6 volts output.
Charging and Regen currents are usually less than 100.0 amps, so
showing -40.6 (amps) worked for me, as my Current Out value.
Power out is usually less than 100 kW, so I show P80.6 for Power Out,
and C30.6 (kW) for Charging power into the Battery Pack, again trying
to identify the values and show the numerics in four "digits".
But, that is just what worked for me, and seemed to make sense
to my somewhat alien (perhaps hybrid) brain.

I will look into restoring HV battery amps in a future update. There are many Leaf parameters that could be read and displayed. I just need to decide on a logical way to show this additional information (like DC/DC converter temperature). Should there be a separate data screen? Should it be user configurable?
Keep in mind that battery amps changes rapidly while driving and the value that was displayed when selecting Alt Gids was only updated every few seconds.
I might add a special monitor mode where only battery amps/voltage are read which would increase the update rate to many times a second at the expense of not reading anything else from the Leaf.
You should be using the new charge graph on screen 2 for that function. It will show you the charge power dropping as the charge level (SOC) increases. No need to look at battery amps.vegastar said:Turbo3 said:Alt Gids were dropped as it was not supported on the newer Leafs.

I use the HV battery amps to check how fast is DC fast charge progressing, so when it slows down I usually disconnect. Also, here in Portugal some DCFC are slower than 125A (I found one that was only 40A...) and this is the only way to know.
Those engineering parameters (Amps, temperatures, etc) are great for many advanced users, but since many users won't find them useful probably they could stay in a separate screen as you suggested.
For now I could just use the old Leaf battery App to check the current during charging, but it would be great to have all these data in LSP.
Good catch.GerryAZ said:Turbo3,
I may have found a bug: I am not sure which version first had the problem, but the SOC% (in lower left corner) does not update on the battery cell screen on my Kyocera Event unless I switch to the screen which shows Gids, SOC, tire pressures, etc. I am using v0.33.39 now. By the way, I like the 12-volt battery information that was added with the latest version.

Do you recall if it was just the 96 cell pair data that got cleared or did it include the VIN, SOH,Hx and other saved data?garygid said:This ver 33.40 seems to have lost all the "previous" data.
No problem if that was intentional, but the previous update
retained the "old" data. FYI, Gary
