Embodiment 1

[0040] Embodiment 1: The detection device for evaluating the thermal consistency of the battery includes: an infrared thermal imager and a control cabinet; the infrared thermal imager is placed above the control cabinet and can cover the control cabinet. The infrared thermal imaging camera can receive the infrared rays reflected by the measured object and convert them into corresponding grayscales, and then obtain the temperature and thermal image of the object according to the grayscale values.

[0041] The control cabinet includes a control unit and a battery placement unit. The battery placement unit is connected to the control unit through wires; figure 2 In , the same letter means the network label, indicating the electrical connection, for example, the positive pole A+ of the first battery of the battery placement unit, the interface A+ of the single-chip microcomputer in the control unit and the interface A+ of the multiplexer are connected.

[0042] The control unit ...

Abstract

The invention provides a battery consistency detection classification method and device, which belongs to battery detection methods and devices. The detection device comprises an infrared thermal imager and a control cabinet. The infrared thermal imager is placed above the control cabinet. The infrared thermal imager receives infrared reflected by a detected object, converts the infrared into corresponding gray, and acquires the temperature and the thermal image of the object according to the gray value. The control cabinet comprises a control unit and a battery placement unit. The battery placement unit is connected with the control unit through a wire. The control unit comprises an electronic load, a charger, a microcontroller and a multiplexer. The charger and the electronic load have multiple channels. The microcontroller is sequentially connected with the electronic load, the charger and the multiplexer. The multiplexer is sequentially connected with the electronic load and the charger. The detection device has the advantages of simple and feasible application and easy control. Mass heat consistency screening test can be carried out. The possibility of battery pack performance variations caused by heat inconsistency in actual use is reduced. Soaking management of a battery management system is reduced.

Description

technical field [0001] The invention relates to a battery detection method and device, in particular to a battery consistency detection and classification method and device. Background technique [0002] Batteries (such as supercapacitors, lithium batteries, etc.) The parameters will also be inconsistent, and the battery will be overcharged or overdischarged during use. [0003] Therefore, the consistency evaluation method of single battery is particularly important. The current single battery consistency evaluation method is to detect the capacity difference of the single battery, the AC and DC internal resistance difference, and the initial voltage difference for matching and screening. There are few reports on the evaluation of battery consistency through thermal effects. Chinese invention patent application 201110360055.X discloses "a method for evaluating the consistency of secondary batteries based on thermal effects". The disadvantage of this method is that the ba...
