Power Supply
This section describes how to power and charge this device.
Energy Harvesting
The device supports self-powered based on thermal energy harvesting. When there is a temperature difference between the ambient temperature and the temperature inside the radiator, the device is able to convert this temperature difference into electrical voltage to charge and store energy.
The device's energy is measured by energy level. Here is the table to indicate the
charge capability:
| Ambient Temperature/°C | Temperature in the Radiator/°C | Difference/°C | Charge Level |
|---|---|---|---|
| 20 | 40 | 20 | 3%/Per day |
| 20 | 45 | 25 | 7%/Per day |
| 20 | 60 | 40 | 12%/Per day |
Emergency Charge
The device can also be powered or quickly charged directly by USB Type-C for
short-term startup operations. Here is the table to indicate the charge
capability:
| Time | Charge Level |
|---|---|
| 30 minutes | 20% |
| 6 hours 30 minutes | 100% |
Energy Level Indication
The device's energy level can be viewed via ToolBox App or uplink reports. It is recommended to check the energy level regularly to know the device's energy status and take measures to charge the device.
| Status | Energy Level |
|---|---|
| Fully charged | 100% |
| Report low energy alarm packet | < 15% |
| Power off automatically | 0% |
| Power up after charging | 17% |
| Force heating start (if enabled) | < 10% |
| Force heating stop by adjusting temperature control targets | >20% |
| Force heating stop automatically | >27% |
