A floor scrubber charger "not charging" usually indicates a combination of six faults. Follow the three steps of "look → test → replace" to quickly pinpoint the problem: I. Overview of the Six Faults | Fault | Symptom | Quick Diagnosis | | 1. No mains power | Indicator light off | Change socket → Light on → OK | 2. Blown fuse | Indicator light off, multimeter no 300V | Multimeter input → No power → Replace fuse | 3. Broken output wire | Light on but no output | Multimeter output → 0V → Replace wire | 4. Reverse battery connection/short circuit | Light flashing or 0V | Replace with same model battery → Normal → Battery faulty | 5. Bulging capacitor | Light on but low output | Multimeter ESR > 0.1Ω → Replace capacitor | 6. MOSFET short circuit | Light on but short circuit | Mult...

  Waterproof smart chargers cannot directly provide "explosion-proof" protection; they represent different levels of safety concepts, but can be used complementaryly in certain industrial scenarios. The conclusions are as follows:   ① Waterproof ≠ Explosion-proof - Waterproof (IP rating) (e.g., IP67) only indicates dustproof and short-term immersion capability, it does not prevent internal electrical sparks, high temperatures, or component failures from igniting surrounding explosive gases; - Explosion-proof (Ex rating) requires that even if a short circuit, spark, or high temperature occurs inside the equipment, it will not ignite surrounding flammable gases or dust, requiring explosion-proof, increased safety, or intrinsically safe structures.   ② Complementary in Industrial Scenarios In explosion-proof areas (e.g., gas stations, chemical workshops), ...

  1.Intelligent Battery IdentificationThe 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 ProfilePre-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 ProtectionChip-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 ProtectionThe NTC monitors the battery and charger temperature in real time.
