AI Technical Summary

Technical Problem

Existing electric vehicle battery pack temperature control systems are susceptible to interference from internal battery current and magnetic fields, resulting in inaccurate temperature detection and failure when the power supply system fails, leading to low cooling reliability.

Method used

The emergency temperature control valve uses a mechanical method to detect temperature and release cooling medium through a thermal expansion section and linkage components, avoiding interference from the electrical control system and using the principle of thermal expansion and contraction for stable and reliable temperature control.

Benefits of technology

It improves the reliability of emergency cooling of the battery pack, avoids the risk of failure of the electronic control system, reduces maintenance costs, and ensures the timeliness and stability of temperature control.

Abstract

本发明提供了一种应急温控机械阀门、电池及温控方法。应急温控机械阀门包括热控膨胀部、冷却部和联动组件。热控膨胀部受热即可使得膨胀腔内的受热介质膨胀或者收缩,进而带动阀体移动,通过联动组件带动阀板打开介质腔释放冷却介质。整个温控过程采用的机械联动方式以及受热介质自身的性能,工作更加稳定可靠。相比于传统的电控检测的方式而言,避免了受内部电场、磁场影响的问题,具有温控及时性。相比于传统的温感机械开关而言,可以避免机械开关部分先降温而导致提前闭合,电池模组降温不充分的情况。本发明的应急温控机械阀门提高了应急降温的可靠性,节约了维护成本。
