Modes of Operation
The SYMIK Intelligent Fast Charging Handle features three distinct operating modes to suit different scenarios:
Figure 7: Triple Mode Design.
- Endurance Mode:
- This is the default power-on mode.
- The screen displays a single lightning icon.
- Provides a maximum output power of 10W (5V@2A).
- Optimized for increased efficiency to extend battery life.
- Fast Charge Mode:
- Double-click the main button to activate Fast Charge Mode.
- The Pocket 3 camera will display 'Fast Charging'.
- The screen will show two lightning icons.
- Provides rapid charging with an output of 20W (9V@2.22A) for the Pocket 3.
- Sleep Mode:
- Press and hold the main button for more than 4 seconds to force power off the battery handle.
- In this mode, the handle can be used solely as a grip without providing power.
Thermal Management and Safety
The SYMIK Intelligent Fast Charging Handle incorporates advanced thermal management features to ensure safe and efficient operation:
Figure 8: Internal thermal management components.
- Multi-layer Thermal Design: Includes Thermal Conductive Silicone Pads, Thermal Insulating Aerogel Foam, an Insulation Layer, a V0 Fireproof Enclosure, and a High-Thermal Conductive Graphene Layer.
- Constant Temperature Control Loop: Ensures stable charging and discharging by monitoring both the chip and battery temperatures.
- IEC-62368 Standard Compliance: Charging and discharge temperature control adheres to the IEC-62368 standard, dividing temperature into five zones with corresponding charging limits for safety.
Figure 9: Temperature Zoning and Charging Strategy.
| Temperature Range | Charging Current | Charging Voltage | Safety Logic |
|---|---|---|---|
| Cold (<0°C) | X Do not charge | X Do not charge | Low-temperature electrolyte solidifies, potentially causing a short circuit, permanent battery loss, and preventing lithium plating. |
| Cool (0–10°C) | ↓ Reduce current | — Maintain standard voltage | Optimal charging range for maximum efficiency. |
| Normal (10–45°C) | ✔ Maximum current | ✔ Standard voltage | Optimal charging range for maximum efficiency. |
| Warm (45–60°C) | ↓ Reduce current | ↓ Reduce voltage | High-temperature lithium ions are active, and high voltage can cause bulging. |
| Hot (>60°C) | X Do not charge | X Do not charge | High-temperature electrolyte decomposition increases the risk of explosion. |
