Description

technical field [0001] The invention relates to a non-contact infrared temperature measuring system for a square battery, which belongs to the technical field of lithium battery formation and capacity testing. Background technique [0002] In the test process of cylindrical lithium batteries, the formation test is to charge the lithium battery with a small current to activate the active material inside the battery and form an SEI film on the surface of the negative electrode material of the battery; the capacity separation test performs several charge and discharge cycles on the lithium battery, using To test the capacity and internal resistance of the battery. For example, in the process of lithium battery formation and capacity separation test, there will be heating phenomenon inside the lithium battery, which will cause the surface temperature of the battery to rise. In order to observe the heating state of the battery, we need to monitor the surface temperature of the ba...
