OMG Introduces Liquid-Cooled Cable Technology, Enabling Over 100km of Range on Charge

China [CN]

During high-power fast charging of electric vehicles, the charging cable withstands a large current and generates significant heat. This heat buildup causes the cable to overheat, shortening its lifespan and potentially leading to physical damage and leaks. While standard cables are generally safe, further increases in charging power and current can cause the cable insulation temperature to exceed safety limits, rendering it unsafe and requiring additional cooling measures.

High-power electric vehicle charging cables are crucial components connecting charging stations and electric vehicles, and their performance is critical to the safety and efficiency of the charging process. When selecting high-power electric vehicle charging cables, the following performance aspects should be considered:

Good Conductivity: Electric vehicle charging cables should possess good conductivity to reduce energy loss and resistance. High-quality conductive materials and design can reduce cable resistance, improve energy transfer efficiency, thereby shortening charging time and reducing energy waste.

High-Temperature Resistance: High-power electric vehicle charging cables generate high temperatures during high-power charging due to the high current and voltage, thus requiring excellent high-temperature resistance. Cable materials should be able to withstand high-temperature environments, maintaining the cable's structural integrity and performance stability, and preventing damage or safety hazards due to excessive heat.

Good abrasion resistance and durability: Electric vehicle charging cables are frequently plugged and unplugged, bent, or dragged on the ground during daily use. The outer layer material of the cable needs to have good abrasion resistance and durability to ensure that the cable is not easily damaged or broken during long-term use.

Environmental adaptability: Electric vehicle charging cables are used in various charging environments. Excellent environmental adaptability extends the cable's service life and ensures electrical safety. For example, waterproofing, moisture resistance, and acid and alkali resistance prevent moisture from entering the cable and causing short circuits or damage. Cable design and material selection are key to ensuring the cable functions normally under various weather conditions.

Interference immunity: High-power electric vehicle charging cables should have good interference immunity to reduce the impact of external electromagnetic interference on the charging process. Shielding technology and excellent cable design can effectively reduce electromagnetic interference and improve the stability and reliability of the charging process.
