Example Embodiment

[0018] Example 1

[0019] At least one temperature test paper 2 is tightly attached to the cylindrical battery casing 1, and the temperature test paper 2 is tightly combined with the battery casing 1. During battery storage, transportation, or use, when the internal temperature of the battery changes, it is conducted to the temperature test paper 1 through the battery casing 2 so that the color of the temperature test paper 2 changes, and the battery surface temperature can be obtained quickly and timely.

Example Embodiment

[0020] Example 2

[0021] At least one temperature test paper 2 is tightly attached to the square or diamond-shaped battery casing 1, and the temperature test paper 2 is tightly combined with the battery casing 1. During battery storage, transportation, or use, when the internal temperature of the battery changes, it is conducted to the temperature test paper 1 through the battery casing 2 so that the color of the temperature test paper 2 changes, and the battery surface temperature can be obtained quickly and timely.

Example Embodiment

[0022] Example 3

[0023] At least one temperature test paper 2 is tightly attached to the battery casing 1, and the temperature test paper 2 is tightly combined with the battery casing 1. During the battery filling process, when the internal temperature of the battery changes, it is conducted to the temperature test paper 1 through the battery casing 2 so that the color of the temperature test paper 2 changes, and the battery surface temperature can be obtained quickly and timely.

[0024] The method can quickly detect the temperature state of the battery during the manufacturing process without additional equipment and installation, and can test any part according to the actual situation, select the temperature test paper type and multi-point test in any combination, and has low cost and reliable effect.

Abstract

The invention provides a battery temperature monitoring method. The surface of the battery case is covered with temperature test paper, and the temperature test paper is closely combined with the battery case; when the internal temperature of the battery changes, it is transmitted to the temperature test paper through the battery case, so that the color of the temperature test paper changes. Thus, the surface temperature of the battery is obtained. The method provided by the present invention overcomes the deficiencies of the prior art, by sticking at least one temperature test paper on the battery shell, the temperature test paper tests the battery surface temperature, and the single battery cells, small battery packs, and large battery packs are tested during the manufacturing process. , During the detection process, during the storage process, during the transportation process, during the use process, etc., quickly detect the temperature status of each battery; the temperature test paper is easy to paste, no additional equipment and installation are required, and any part can be tested according to the actual situation, and any combination Selecting the type of temperature test paper and multi-point testing has a very positive effect on battery monitoring and screening.

Description

technical field [0001] The invention relates to a battery temperature monitoring method, which belongs to the technical field of batteries. Background technique [0002] As an important part of renewable energy and new energy, batteries are not only seen in portable electrical appliances, but also in energy storage, electric bicycles, and electric vehicles, which have an increasingly important impact on people's lives. With the development of the battery industry, battery-related safety issues have become more and more prominent, and temperature, as an important indicator of batteries, has received more and more attention. [0003] At present, in the battery temperature test system, the traditional battery temperature monitoring method is through temperature sensor detection and external electronic detection equipment, which requires special instruments or equipment, which is only suitable for the monitoring of a small number of batteries in the test or production process, s...
