-Optional properties:
- - active-semi,check-battery-temperature: boolean to check the battery
-   temperature or not.
- - active-semi,input-voltage-threshold-microvolt: unit: mV;
-   Specifies the charger's input over-voltage threshold value;
-   The value can be: 6600, 7000, 7500, 8000; default: 6600
- - active-semi,precondition-timeout: unit: minutes;
-   Specifies the charger's PRECONDITION safety timer setting value;
-   The value can be: 40, 60, 80, 0; If 0, it means to disable this timer;
-   default: 40.
- - active-semi,total-timeout: unit: hours;
-   Specifies the charger's total safety timer setting value;
-   The value can be: 3, 4, 5, 0; If 0, it means to disable this timer;
