Hi,
I have a Cube Orange Standard Set (ADS-B Carrier Board) with ArduRover 4.0.0 and Mission Planner 1.3.74
I’m having trouble configuring the Current readings from the two Cube Power Brick Minis I have connected to POWER1 and POWER2.
I have looked at the doco here The Cube User Manual V1.0 - CubePilot
and tried to follow that but only seem to get stable voltage results when I configure things slightly differently.
For the first battery
here is what works for me under SETUP > OPTIONAL HARDWARE > BATTERY MONITOR
Monitor = Analogue Voltage and Current
Sensor = 0:Other
HW Version = blank, no entry at all.
Then to calibrate I measure the battery voltage with my Multimeter and put that value into “1. Measured battery voltage”.
that results in pretty accurate voltage measurements in Mission Planner, I totally understand that a bit of error (say +/- 0.2v) is to be expected.
I did also look in the CONFIG > FULL PARAMETER TREE > BATT >
where BATT_CURR_PIN = 15 Cube Orange
and BATT_VOLT_PIN = 14 Cube Orange
can’t recall if I sett both of those myself.
For the second battery
here is what works for me under SETUP > OPTIONAL HARDWARE > BATTERY MONITOR 2
Monitor = Analogue Voltage and Current
Volt Pin = Pixhawk2_PM2/CubeOrange_PM2
Current Pin = CubeOrange_PM2
Then to calibrate I measure the battery voltage with my Multimeter and put that value into “1. Measured battery voltage”.
again thats giving me a pretty good voltage reading.
I did also look in the CONFIG > FULL PARAMETER TREE > BATT2 >
where BATT_CURR_PIN = 4 CubeOrange_PM2
and BATT_VOLT_PIN = 13 Pixhawk2_PM2/CubeOrange_PM2
can’t recall if I sett both of those myself.
The questions I have are around getting the current readings correctly from those two Power Bricks.
Battery 1 (12-13v SLA) has nothing other than the Power Brick connected, and that is in turn connected to Cube POWER1. So my understanding is the Cube will be selecting that as its internal power source and drawing up to 0.5A depending on the situation. With my multi meter I can see that current (bouncing around 0.2 - 0.4A) but in Mission Planner I see 0.0A??
Battery 2 (12.8v LiFePo) is connected to the 2nd Power Brick which is in turn connected to the Cube POWER2 and also via the bricks downstream XT60 connector to my ESC and motor.
When my motor is not running, Mission Planner is showing about 0.15A current for Batt2 which makes sense as the ESC has a BEC and so I guess a little current is in use. But when I throttle up my motor, which I know is drawing about 1A (I have another power monitor inline) the current for Batt2 in Mission Planner just stays at the 0.15A???
I’m pretty new to all of this so any suggestions welcome
Thanks,
Paul
