[0002] The power battery is the "heart" of a new energy electric vehicle, accounting for 30%-40% of the total vehicle cost. Its performance directly affects the range and safety of the electric vehicle. To comprehensively evaluate the performance of the power battery, it is necessary to test and verify it from aspects such as electrical performance, environmental reliability and safety performance. The battery testing usually includes the following methods: airtightness test, burst pressure test, breathing cycle test, integrated breathing and burst test, pressure loading test, etc.

[0003] However, when testing the burst pressure of a battery, the cover of the battery pack is usually clamped and the air pressure is used to impact the explosion-proof disc. Since the explosion-proof disc is small, it is inconvenient to control its installation position when the cover is placed. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-5 As shown, this embodiment provides a new energy vehicle battery testing device, including an air supply base 1 and a pressurizing base 2. A lower pad 3 is installed on the upper surface of the air supply base 1, and a movable pressure plate 4 is arranged directly above the lower pad 3. An adjustment mechanism 6 is installed on one side of the lower pad 3 on the upper surface of the air supply base 1. The adjustment mechanism 6 includes a guide slide rail 601 and a stop block 603. The guide slide rail 601 is fixedly connected to the air supply base 1. A groove 602 is opened on the upper surface of the guide slide rail 601. The stop block 603 is slidably connected to the groove 602. A spring 604 is connected between the inside of the groove 602 and the stop block 603. The spring 604 is fixedly connected to both the guide slide rail 601 and the stop block 603. A graduated groove 605 is opened on the side surface of the guide slide rail 601. A limiting bolt 606 is installed on one side of the stop block 603 at the position corresponding to the graduated groove 605. The limiting bolt 606 is engaged and rotatably connected to the stop block 603.

[0018] like Figure 2-3 As shown, in this embodiment, an upper pad 401 is installed on the lower surface of the movable pressure plate 4 at the position corresponding to the lower pad 3. A hydraulic rod 403 is installed on the lower surface of the upper pad 401. A positioning insertion hole 302 is opened on the upper surface of the movable pressure plate 4 at the position corresponding to the hydraulic rod 403. The upper pad 401 is limited and locked with the positioning insertion hole 302 by the hydraulic rod 403. A positioning insertion rod 402 is installed on the upper surface of the movable pressure plate 4. An air nozzle 301 is opened on the upper surface of the lower pad 3. An air supply mechanism is installed below the air nozzle 301 inside the air supply base 1. A guide rod 5 is installed on the upper surface of the pressurizing base 2 through the interior of the movable pressure plate 4.

[0019] The working principle of this utility model is as follows: During use, the length of the cover plate to be tested is measured. The positions of the lower pad 3 and the internal air nozzle 301 are fixed. Therefore, by sliding the stop block 603 in the internal groove 602 of the guide rail 601, the distance from the center of the air nozzle 301 to the end of the lower pad 3 is added to the scale reading on the graduated groove 605 to make it the same as the distance reading from the rupture disc to the end of the cover plate. Then, by applying torque to the limiting bolt 606, the stop block... After 603 is fixed to the outside of the guide rail 601, the cover plate is placed over the lower pad 3, so that the rupture disc is positioned above the air nozzle 301. The movable pressure plate 4 is then moved downward above the guide rod 5, so that the positioning hole 302 on the lower surface of the air nozzle 301 is inserted into the positioning hole 302. After the lower pad 3 and the movable pressure plate 4 clamp the cover plate, the air nozzle 301 is used to pressurize the rupture disc for testing.
