1.Intelligent Battery Identification
The MCU automatically distinguishes between lead-acid, lithium, and ternary lithium batteries, dynamically switching the charging curve. Charging stops when fully charged, with a ripple of <50 mV and a 30% increase in battery life.

2. Multi-stage Charging Profile
Pre-charge → constant current → constant voltage → float charge. Pulse desulfation and capacity restoration are implemented throughout the charging process, allowing for a full charge even in winter.

3. Five-Level Safety Protection
Chip-level monitoring for overcharge, overcurrent, overvoltage, short circuit, and reverse polarity. Abnormality is shut off within 0.1 seconds, ensuring spark-free and bulging-free operation.

4. Temperature Protection
The NTC monitors the battery and charger temperature in real time. Automatically reduces power when the temperature exceeds 45°C and stops output when the temperature exceeds 60°C, ensuring no "shield protection" in summer.

5. Waterproof and Dustproof (IP65/IP67)
Aluminum housing and adhesive potting ensure stable operation in heavy rain, salt spray, and dust. No outdoor charging shelter is required.

6. Automatic Battery Identification
Plug and charge instantly, no buttons required. LED/PWM real-time status display makes it easy to see even in dark environments.

7. Low Standby Power Consumption
No-load power consumption is less than 0.5 W, saving 8% compared to traditional three-stage chargers and saving 40 kWh of electricity per year.

8. Wide Voltage Input
Compatible with 18–72 V, 5–8 batteries can be connected in series, allowing for multiple uses with one charger, even when the device is replaced.

9. Automatic Recharge Integration
Linked with the robot vacuum's SLAM system, with an accuracy of less than 5 mm, it automatically recharges at 20% charge, ensuring unattended operation.

10. Programmable & OTA
Remotely adjust voltage, current, and cut-off conditions via the app or cloud. OTA firmware updates ensure constant functionality.

— Choosing a charger means choosing "battery life + safety + electricity costs."
