Description

Technical Field

[0001] The utility model belongs to the technical field of battery testing, and particularly relates to a battery charging and discharging probe with active heat dissipation. Background Art

[0002] Since the development of energy storage technology to date, various energy storage technologies have been provided and developed to meet the applications for different fields and different requirements. Lithium batteries have been widely used in daily life due to their advantages such as high energy density, long cycle life, wide operating temperature range, and high safety. For example, in new energy vehicles, lithium batteries have become an important part of new energy vehicles, and gradually achieve industrialization with an expanding scale. The production of lithium batteries includes steps such as stirring, coating, cold pressing and pre-cutting, tab die-cutting and slitting, winding, baking and liquid injection, formation, feeding, plasma cleaning, cell gluing, laser welding, and offline testing. Among them, the charge and discharge test during the formation process is a relatively important link in the production process, and usually probes are used for the charge and discharge test. When the battery is formed, it is necessary to detect the current, voltage changes and temperature changes of the storage battery. The probe is usually above the battery to be formed, a battery detection is set, and the probe is in contact with both poles of the storage battery to detect and control the current and voltage changes of the storage battery. Only after the formation and grading of the battery can it be used normally. Formation refers to the first charging of the battery by contacting the probe assembly with the battery terminal to activate the battery. During the battery charging process, since a large amount of heat is generated at the battery terminal during charge and discharge, the temperature of the probe will also increase simultaneously. If the probe is used for a long time in this environment, it is extremely easy to cause damage to the probe and may also affect the quality of the battery. The existing probes all adopt the passive heat dissipation scheme, that is, after the probe works and generates heat, heat dissipation structures such as heat sinks are set to quickly dissipate heat by itself to improve the use performance. Therefore, the utility model proposes a fast heat dissipation type probe. Summary of the Invention
