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.

  The fully charged voltage of a single lithium iron phosphate (LiFePO₄) cell is 3.65 V. Formula for calculating the number of strings: Number of strings = Full-charged battery pack voltage ÷ 3.65 V Example- 48 V battery pack: 48 ÷ 3.65 ≈ 13 strings (actual 13 × 3.65 = 47.45 V).- 60 V battery pack: 60 ÷ 3.65 ≈ 16 strings (actual 16 × 3.65 = 58.4 V). Remember: 18.25 V indicates a fully charged LiFePO₄ battery pack with 5 strings (3.65 V × 5).
