| - cm-fullbatt-soc : state of charge to consider as full battery |
| - cm-fullbatt-capacity : capcity (in uAh) to consider as full battery |
| - cm-thermal-zone : name of external thermometer's thermal zone |
| - cm-battery-* : threshold battery temperature for charging |
| -cold : critical cold temperature of battery for charging |
| -cold-in-minus : flag that cold temperature is in minus degrees |
| -hot : critical hot temperature of battery for charging |
| -temp-diff : temperature difference to allow recharging |
| - cm-dis/charging-max = limits of charging duration |
| |
| Deprecated properties: |
| - cm-num-chargers |
| - cm-fullbatt-vchkdrop-ms |
