Description

Technical Field

[0001] This utility model relates to the technical field of equalization charging device structure, and in particular to a patch-type battery module equalization charging device. Background Technology

[0002] The main function of a power battery equalizer is to collect and determine the voltage parameters of individual battery cells, and then perform related maintenance on the battery pack using a "series charging compensation" method. This restores the individual cells within the battery pack to their factory-set levels, ensuring they are in optimal working condition and addressing inconsistencies within the battery pack.

[0003] A search revealed that patent announcement number CN208707358U discloses a battery equalization charging device, including a battery pack, a battery management controller, and fiber Bragg grating sensors. The battery management controller is connected to the fiber Bragg grating sensors. Multiple fiber Bragg grating sensors are provided, each mounted on a different battery cell connecting piece. The battery cell connecting piece connects two electrodes of the same polarity within the battery cell. This device has a simple structure, high reliability, and prevents overcharging, over-discharging, and overcurrent of the battery cells within the battery pack, effectively extending the cycle life of the battery pack.

[0004] However, in the existing technology, when the equalizer is connected to the electrode plates of each battery cell in a battery pack, since there are a large number of electrode plates in a battery pack, each electrical connector needs to be clamped onto the electrode plate. The battery electrode plates are relatively flat and there is no special place to clamp them, which is time-consuming and laborious. Therefore, there is an urgent need in the market for a surface-mount battery module equalization charging device to solve these problems. Utility Model Content
