Do not allow your car battery to reach 0% SOC, and if it does, plug in and charge the car immediately. Failure to do this can result in unrecoverable failure of the car’s battery.
The module can monitor the main and 12V battery and send alert notifications if the SOC or voltage drops below a healthy level.
Average Power Usage¶
The power used by the module depends on the component activation. You can save power by disabling unused components. This can be done automatically by the Power Management module to avoid deep discharging the 12V battery, or you can use scripts to automate switching components off and on.
The base components need approximately these power levels continuously while powered on:
|Component||Avg Power||12V Current|
|Base System||200 mW||17 mA|
|Wifi||330 mW||28 mA|
|Modem||170 mW||13 mA|
|GPS||230 mW||19 mA|
|Total||930 mW||78 mA|
This adds up to:
- ~ 22 Wh or 2 Ah / day
- ~ 156 Wh or 13 Ah / week
- ~ 680 Wh or 57 Ah / month
Note that depending on the vehicle type, the module may also need to wake up the ECU periodically to retrieve the vehicle status. Check the vehicle specific documentation sections for hints on the power usage for this and options to avoid or reduce this.
