Cylindrical batteries are currently the most popular lithium-ion batteries, and many automobile manufacturers have successively developed and released a number of new energy vehicles with cylindrical cells as monomers. Therefore, the testing and development of cylindrical batteries is extremely important. In order to keep the battery cells in the same way in the whole vehicle, it is best to place the battery cells vertically during the test.
[0003] In order to complete the test of the battery's electrical performance and other performance aspects quickly, effectively and reliably, existing battery testing manufacturers often use universal battery testing tools and matching instruments. However, this type of universal battery testing equipment often has the problem of mismatch between the current line and the battery size; since most cylindrical cells are small in size, it is difficult to maintain an upright state for testing without the assistance of a fixture after connecting the test power line, so the development of a fixture for cylindrical cells is particularly important.
