Abstract

The invention belongs to the technical field of batteries, in particular to an environment temperature control system of a battery cell test. The system comprises at least one first closed test area and at least one second closed test area, the first closed test area is provided with a first temperature adjustment apparatus and at least one battery cell test device, the second closed test area is provided with a second temperature adjustment apparatus and at least one battery cell, and the battery cell test device is electrically connected with the battery cell. By adopting the test mode, the test environment temperature can be accurately controlled, and the test cost is low; and furthermore, the the system is has the advantages of environmental protection and low energy consumption, simple structure, easy control of the test temperature, stable operation and high efficiency. In addition, the invention further provides a control method of the system, so as to improve the stability and efficiency of the system.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to an environment temperature control system and a control method for battery cell testing. Background technique [0002] In the lithium battery industry, it is necessary to monitor the cycle life of the cell to simulate the attenuation of the cycle life of the cell during actual use. This attenuation is not only related to the cell itself and the test equipment, but also to the temperature of the test environment for the cycle life. Its test results will have a great impact. [0003] In order to control the ambient temperature, there are the following methods in the prior art: 1. Use an air conditioner to control the ambient temperature in the test area; 2. Use a preset temperature test box to control the ambient temperature. Method 1 Since the cycle life test equipment will generate a lot of heat during operation, in addition to reducing the temperature control accu...
