As new energy vehicles gain widespread adoption, "range anxiety" has become a critical industry concern. Compared with DC fast charging that typically lasts 30 to 60 minutes, the battery swap mode reduces energy replenishment time to within 5 minutes, bringing a marked improvement in user experience. This is supported by a high-reliability, high-precision automatic positioning system, where non-attenuation inductive sensors serve as the core "eyes" for positioning.
The battery swap process places rigorous technical requirements on sensors across multiple dimensions:
• Metal diversity: Owing to varied design specifications and cost tiers of different vehicle models, battery pack housings are made of diverse materials. Inductive sensors may suffer from "long-distance instability" or "short-distance false triggering" caused by varying attenuation coefficients.
• Harsh environmental resilience: Vehicle chassis are frequently contaminated by muddy water and ice; in northern winters with low temperatures, sensors must meet IP67 or higher protection standards to ensure stable operation within the specified temperature range.
• Strong magnetic field immunity: High-power chargers and servo motors in swap stations undergo frequent start-stop cycles, making EMC performance a critical factor in determining system downtime risks.
• Long service life: With over 1,000 battery swap operations per station per day during peak periods, sensors must exhibit excellent durability for prolonged service.
The Factor One inductive sensor offers an effective solution to these challenges.
Defined by a coefficient K≈1, non-attenuation ensures the sensor maintains an almost uniform detection distance across diverse metals, including iron, stainless steel, copper, and aluminum. This eliminates the need for repeated installation position adjustments for different vehicle models, enabling a single swap channel to accommodate multiple chassis configurations such as sedans and SUVs.
Boasting an extremely low attenuation coefficient, the sensor achieves a substantial extension in detection distance, generating longer-range and more stable trigger signals within a fixed installation space, thus providing enhanced mechanical tolerance for shuttle vehicles and battery pallets.
