Abstract

The invention discloses an electric vehicle battery core testing device, comprising a battery core feeding port, a battery core support, an alignment plate and a testing component. The lower end of the plate is connected to the hinge plate by the spring one, and the lower end of the cell feed port is connected to the cell support. The upper and lower surfaces of the cell support are respectively provided with an upper battery slot and a lower battery slot, and the upper and lower surfaces of the cell support are also There are upper protrusions and lower pits respectively. When the cell support moves horizontally, the upper protrusion is connected to the lower end of the hinge plate. When multiple cell supports are stacked, the upper protrusion is connected to the lower pit; the cell feeding port The height is adjustable; there is also a temperature sensor in the middle of the cell holder; there are two alignment plates, and the two alignment plates are symmetrically arranged, and the test assembly is used to detect the cells placed between the multi-layer cell holders. The invention can quickly and efficiently relocate the battery cells after purchasing, and quickly perform the performance test and monitoring of the battery cells.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery testing, in particular to an electric vehicle battery testing device. Background technique [0002] Electric vehicle batteries are usually composed of multiple 18650 cells connected in series or parallel in some way. Electric vehicle manufacturers need to perform performance tests on the cells after purchasing the cells. The performance tests include charge and discharge performance tests, and temperature tests during charging and discharging. , the test time is long and there are many test items. However, it is not possible to test the cells directly after purchase, because the spacing between the cells during testing is different from that in the cell packaging box at the time of purchase, and the cells need to be rearranged before testing , the number of battery cells is large, so a battery test device capable of satisfying multiple battery cell tests is needed in the prior ar...
