Description

Technical Field

[0001] The utility model relates to the field of multi-cavity independent temperature-controlled battery testing cabinets, and more particularly to a multi-cavity independent temperature-controlled battery testing cabinet. Background Art

[0002] Batteries are used more and more frequently in people's daily lives. Generally, batteries need to undergo some tests before use to determine whether they are qualified, including voltage internal resistance test, capacity test, overcharge, over-discharge, short-circuit test and other test contents. During the test, the battery may explode or burn, and even endanger the safety of the staff. Therefore, some protective measures are taken during battery testing, such as battery explosion-proof test box. The test box in the existing technology is generally a large box, and all batteries are placed in one box. If an individual battery has an abnormality (explosion or combustion) during the charge and discharge test, it will cause unnecessary damage to the adjacent batteries and related experimental equipment. In addition, the existing test box can only regulate the overall temperature inside the box, and cannot simultaneously meet the specific ambient temperature requirements of different types of battery tests, or different test temperature conditions for the same type of battery. In other words, batteries with different test ambient temperature requirements cannot be tested at the same time, which greatly reduces work efficiency. At the same time, the wiring in the existing test box is complicated. Each battery tray in the box needs to be connected to multiple bundles of wires. All wires are inserted into the box through the wiring channel on the side wall of the box, and then connected to the battery one by one. It is very cumbersome and easy to connect the wrong wires.

[0003] Among its existing technology patents, such as the authorization announcement number CN211928451U, a multi-chamber independent temperature-controlled battery test cabinet includes a cabinet body, on which are arranged multiple independently arranged constant temperature chambers. Each chamber has an opening on the side for installing an adapter plate, which can facilitate the connection of cables to the battery test cabinet; a guide rail for plugging and unplugging the battery fixture to be tested is provided on the inner wall of the constant temperature chamber, and the battery fixtures in each constant temperature chamber can be plugged and unplugged along the guide rail and the adapter plate; each constant temperature chamber is provided with an independently controllable refrigeration unit, an independent heating unit and a fan; the refrigeration unit of each chamber is provided with cooling by a compressor, and each chamber is independently controlled by a solenoid valve;

[0004] In the above patent, for example, the temperature in each constant temperature chamber can be independently controlled to meet the simultaneous testing of batteries at different temperatures; the cable is connected to the temperature control box through an adapter plate on the side, and the battery test fixture can be directly connected to the adapter plate through a connector, avoiding the need to remove the cable when replacing the battery;

[0005] The battery furniture structure is an integral structure. Different batteries cannot be clamped independently during testing, and the batteries are not independently installed and clamped, which is inconvenient during testing. In addition, the cabinet body is provided with multiple cavities, and the space is small when wiring inside and outside, making wiring inconvenient. Utility Model Content
