Description

Technical Field

[0001] This utility model belongs to the field of battery pack configuration technology, specifically relating to a battery voltage matching device. Background Technology

[0002] A battery voltage matching device is a device or system used to match and equalize the voltage of individual cells in a battery pack. Voltage matching is a critical step in the battery pack configuration process, ensuring that the voltage of each individual cell in the pack is as consistent as possible, thereby improving the overall performance and stability of the battery pack.

[0003] Current battery voltage matching devices inevitably generate a certain amount of heat during continuous operation. If this heat is not dissipated in a timely and effective manner, it may adversely affect the performance and stability of the device. However, current devices mainly rely on their own designed heat dissipation holes to dissipate heat; although this method can alleviate the problem of heat accumulation to some extent, its overall heat dissipation efficiency is relatively low. The design of the heat dissipation holes is often limited by the overall structure and size of the device, making it difficult to achieve ideal heat dissipation. Especially under long-term high-load operation, the heat dissipation holes may not be able to meet the demand for rapid heat dissipation, causing the internal temperature of the device to rise continuously, which may lead to a series of performance degradation problems or even failures.
