Green New Energy: Application of JINPAT LPA High-Current Slip Rings in Charging Stations

I. Industry Background:
The "high current" trend in the new energy market stems from the continuous increase in battery capacity of new energy vehicles, leading to a growing demand for "ultra-fast charging" and "automatic charging robots." This requires the rotary joints inside the charging piles to not only possess extremely high current carrying capacity but also to adapt to various outdoor weather conditions. The JINAPT LPA series high-current slip ring is a core conductive component designed to meet the needs of this vast and promising market.

II. Core Technological Advantages of the LPA Series
1. Perfect Balance of High Current and Compact Structure
Within the limited internal space of the charging pile, the LPA series achieves a breakthrough in current transmission capacity. High-density design: The clever structural design effectively reduces the axial length and outer diameter, greatly saving installation space for the charging arm or rotating base.
2. Intelligent Temperature Control System
The thermal effect accompanying high-current transmission is a major challenge facing the industry. The LPA series integrates a real-time temperature monitoring system: Active protection: Built-in high-precision temperature sensors provide real-time feedback on contact temperature rise. Safety assurance: When the temperature exceeds a preset threshold, the system can link with the charging pile controller to reduce power or trigger an alarm, preventing hardware damage caused by overheating and ensuring the safety of continuous high-current operation.
3. Rigorous Waterproofing and Environmental Adaptability
The LPA series is specifically designed for the heavy rain environments that outdoor charging piles may face, with a protection rating of IP65, and has successfully passed the following rigorous waterproof testing procedures:
Test equipment: Nozzle inner diameter 6.3mm.
Water flow control: (12.5 ± 0.625) L/min.
Spray intensity: Water pressure is precisely adjusted according to the specified flow rate.
Duration: Continuous spraying for 5 to 10 minutes (spraying time per square meter of the housing surface is greater than 1 minute).
Spraying distance: The distance between the nozzle and the product housing is maintained at 2.5m to 3m.
This protection level ensures that even in strong water spray environments, the precision conductive rings and brushes inside the slip ring remain dry, avoiding the risk of short circuits.

III. Application Value: Improving the Reliability of Charging Facilities
Using JINAPT LPA slip rings can solve the problems of entanglement and fatigue fracture of high-power charging cables during rotation. This slip ring is unaffected by rain, snow, and dust, reducing maintenance frequency and operating costs, and easily meeting the demands of future higher-power DC fast charging technologies.
