Description

Technical Field

[0001] This utility model relates to the field of lithium battery power supplies, specifically a lithium battery power supply for testing. Background Technology

[0002] Lithium-ion batteries are battery systems that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They are characterized by high energy density, long cycle life, and low self-discharge rate, and feature high nominal voltage and smooth discharge voltage. Based on whether they are rechargeable, lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries.

[0003] While existing lithium-ion battery power supply designs excel in energy density, cycle life, and portability, they often face challenges in practical applications due to the lack of additional fixing structures. This is particularly true in applications requiring high stability and reliability, such as drones, electric vehicles, and high-end electronic devices, where misalignment of the lithium-ion battery power supply is a frequent occurrence. This can not only affect the normal operation of the equipment but also potentially lead to safety accidents. Therefore, adding an effective fixing structure to the lithium-ion battery power supply to prevent misalignment during operation is of paramount importance. Utility Model Content
