Problems solved by technology

[0004] In the existing restraint tray, when multiple batteries are placed on the base of the tray, the clamping plate is squeezed and clamped as a whole to realize the restraint and positioning of each battery cell. Since the multiple batteries are arranged in a row, The overall pushing and positioning will easily cause a large cumulative error, resulting in the inability of some probes to be accurately aligned with the electrodes; repeated adjustments are required, which reduces the efficiency of the test, and the tray has poor adaptability to square cells of different sizes

Abstract

The invention provides a restraining tray for battery cell testing, which is provided with a base for bearing a battery cell, and further comprises a plurality of fixed clamping plates and a restraining unit, the fixed clamping plates are arranged side by side and are fixedly arranged on the base, and the restraining unit is arranged on the base. A plurality of clamping plates in one-to-one correspondence with the fixed clamping plates are fixedly arranged on the restraining unit, the battery cells are arranged between the corresponding clamping plates and the fixed clamping plates, and when the clamping plates move along with the restraining unit and approach the fixed clamping plates, the battery cells can be synchronously clamped between the clamping plates and the fixed clamping plates. According to the restraining tray for the battery cell test, accumulated errors generated in the process that a plurality of battery cells are pushed and clamped can be avoided, and therefore good conditions are provided for accurate alignment of the probes and the electrodes.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a restraint tray for battery cell testing. Background technique [0002] In the current field of new energy vehicles, power batteries are one of the key power sources, and their safety is very important. For example, lithium-ion batteries are composed of multiple cells. Before each cell is assembled into a battery module, it needs Its various performances are tested to verify its load capacity and safety performance. [0003] The test generally needs to be carried out on a restraint tray to test multiple cells at one time; the tray is equipped with multiple probes that are electrically connected to external testing instruments. Time-shifting, each probe corresponds to the electrode of the cell one by one and touches and conducts, so as to carry out subsequent performance tests. [0004] In the existing restraint tray, when multiple batteries are placed on the base of th...
