Description

Technical Field

[0001] The utility model relates to the technical field of battery detection, specifically a vehicle-mounted battery internal resistance detector Background Art

[0002] Battery tester, also known as battery tester or battery analyzer, is a professional analysis and testing equipment for judging the working capacity of automobile batteries. Although automobile batteries do not account for a high proportion of the cost of automobiles, they play a vital role in the entire car. Therefore, knowing whether the automobile battery is still in good condition and replacing the battery that is about to be scrapped in advance can effectively improve the company's service level and user satisfaction, and bring great convenience to battery manufacturers, automobile production lines, automobile repair companies, battery dealers and other users in battery testing.

[0003] When optimizing existing battery internal resistance testers, most of the improvements are reflected in the effect of the device on internal resistance detection. For example, the Chinese utility model patent with application number CN202021647921.4 discloses "A battery internal resistance tester for battery testing". This utility model patent is equipped with a fixing device, and a hand-held knob is used to drive the threaded rod to rotate in the inner cavity of the threaded sleeve. The threaded rod drives the fixed plate to move inward, and the fixed plate drives the slider to slide in the inner cavity of the cross plate when it moves, so as to fix the battery for testing. It has a good fixing effect and can fix batteries of different specifications and sizes for testing.

[0004] Although the above method has certain advantages in terms of improvement, it still has certain disadvantages: when the battery is tested, the wires inside the device will heat up. If the heat dissipation effect is not good, most of the heat will be inside the device, causing the temperature inside the device to rise rapidly, which may cause the battery to explode and endanger the safety of personnel.
