Description

Technical Field

[0001] This application relates to the field of new energy battery technology, and more specifically, to a locking structure for a soft connector of a new energy vehicle battery. Background Technology

[0002] New energy vehicle battery flexible connectors are important components used to connect various parts of the battery module. Their main function is to provide electrical connection and mechanical support. They are usually made of flexible conductive materials and can adapt to the expansion and contraction of the battery pack caused by factors such as temperature changes and vibration. Flexible connectors can effectively reduce stress concentration caused by rigid connections, extend battery life and improve safety. Common flexible connector materials include copper and aluminum alloys. The surface is usually treated with anti-corrosion to ensure good conductivity and durability.

[0003] Regarding the aforementioned technologies, the inventors believe that in the existing technology, traditional soft connectors for new energy vehicle batteries typically use soldering to connect battery modules. However, over time, soldering connections will oxidize. The oxide layer at the solder joint not only leads to a decrease in conductivity but may also cause poor contact, affecting the overall performance of the battery pack. Oxidation gradually increases contact resistance, thereby exacerbating energy loss within the battery pack and further affecting the battery's charging and discharging efficiency. Over time, oxidation may cause the battery temperature to rise, increasing the risk of battery overheating and failure, thus affecting the safety and reliability of new energy vehicles. In addition, the mechanical strength of soldered connections is low, making them susceptible to external factors such as vibration and temperature changes, leading to loosening or breakage of the connections. This also increases the difficulty and frequency of battery pack maintenance. Oxidation and poor contact problems may also lead to a shortened battery life. Utility Model Content
