With the popularization of new energy vehicles, ultrafast charging is becoming a new travel fashion. Ultra fast charging models can complete charging within 5 to 10 minutes. According to Huawei MI data, it is expected that by 2026, models based on high-voltage fast charging platforms will occupy 50% of the entire new energy vehicle market, with a total ownership of 5.8 million vehicles in the Chinese market
With suppliers such as CATL, Xinwangda, Guoxuan High tech, and Dawan Technology launching ultrafast charging batteries, more and more ultrafast charging guns are adopting liquid cooled fast charging solutions to cope with high voltage, high current, and high-power transmission.
Liquid cooled ultra fast charging involves adding a dedicated liquid circulation channel between the charging cable and the charging gun. Introduce coolant into this channel to dissipate the heat generated during the charging process. The power pump drives the circulation of coolant, effectively taking away heat. This requires charging guns and cable materials to have high thermal conductivity, strength, and toughness.
——Thermal conductive potting material quickly dissipates heat from the tip of the charging gun
Fill the space at the tip of the charging gun with thermal potting material, ensuring complete coverage and sealing of the charging gun tip.
Ensure close contact between the thermal potting material and the surface of the charging gun tip, and eliminate possible bubbles or gaps to maximize thermal conductivity efficiency.
——PUR 1608（1#） Super heat dissipation new experience
PUR 1608 (1#) is a two-component solvent-free room temperature or heat curing resin elastomer composite used for two-component sealing and filling. The raw material does not contain heavy metals, green environmental protection, wide process operability, high physical properties of the finished product, and good adhesion to the substrate. Both room temperature and heating can be cured, can be deeply cured, the two components have good fluidity after mixing, and excellent flexibility after curing.
