Questions
Question | Answer |
|---|---|
How do we access aux battery voltage and temperature? | Analog Inputs, voltage (voltage divider fed into buffer then controller) |
How do we find the status of DCDC? | Analog sensors (same as AUX) |
Do we have any protection for the AUX battery? | No built in protection on the board. Software fault can be made. Want to detect: over voltage (would like to discharge the AUX battery without having to remove battery) , under voltage (use time delay to check for under voltage dips), over current (current is analog input) Don’t necessarily need to cut power immediately with power spikes. |
Do we charge the Aux battery? | Would like to, but not a priority. (so no). |
What’s the valid range of the AUX battery voltage and temperature? | Using a 10s NiMH battery Voltage 9.4 V - 15 V Temperature Charge - 0 to 45 degrees C Discharge - -20 to 50 degrees C  |
