Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a method for testing the performance of a lithium-ion battery of a farmland wireless sensor network node. Background technique [0002] Traditional agriculture mostly uses isolated mechanical equipment without communication capabilities, mainly relying on manpower to survey soil conditions, track temperature and moisture, and detect the growth cycle of crops. This will not only consume a lot of human and financial resources, but also cause delays in information, which will affect timely decisions on crop management. The use of wireless sensor networks can accurately obtain crop environmental information and crop growth status data. Since sensor nodes are often deployed in complex and harsh environments, it is impossible to access the normal power system for power supply in most cases. At present, sensor nodes mainly rely on lithium-ion batteries for power supply. ...
