Abstract

The invention provides a lithium dendritic crystal elimination method and device and a computer readable storage medium, and the method comprises the steps: monitoring the real-time capacity of a battery cell in a use process of the battery cell; when the real-time capacity is reduced by a preset percentage each time, heating the battery cell to a preset temperature range; after the battery cell is heated to the preset temperature range, circularly charging and discharging the battery cell for a first number of times according to a first charging and discharging rate; and circularly charging and discharging the battery cell for a second number of times according to a second charging and discharging rate, the second charging and discharging rate being smaller than the first charging and discharging rate. By means of the technical scheme, the lithium dendrites can be efficiently and thoroughly eliminated while the performance of the battery cell is protected, the negative influence of the lithium dendrites on the performance of the battery cell and even the driving safety of the whole vehicle is reduced, the safety of the battery cell is greatly improved, finally, the service life ofthe battery cell can be prolonged, and the cruising ability is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a method and device for eliminating lithium dendrites and a computer-readable storage medium. 【Background technique】 [0002] Lithium deposition is a common phenomenon in the battery cell of the vehicle's power battery. After lithium deposition in the battery cell, lithium dendrites will be generated on the surface of the battery cell. A large number of lithium dendrites cover the surface of the battery cell, which will greatly affect the performance of the battery cell. [0003] Therefore, how to promptly eliminate the lithium dendrites produced by the lithium analysis of the battery cell has become an urgent technical problem to be solved. 【Content of invention】 [0004] Embodiments of the present invention provide a method and device for eliminating lithium dendrites, a battery management system, a vehicle, and a computer-readable storage medium, aiming to solve the tech...
