The power battery drop tester is mainly used to evaluate the safety performance of other primary batteries, secondary batteries, battery cells or battery packs of various types of lithium batteries and nickel batteries (for example, from the top of the table top). The battery is qualified to not explode without fire. 1. This machine adopts single-arm and double-column structure, with electric reset, electric control drop and electric lifting device. It is easy to use and unique hydraulic buffer device greatly improves the service life, stability and safety of the machine. 2. The single arm setting can be conveniently placed at the same time, and the angle error between the impact angle impact surface and the bottom plate plane is less than or equal to 1 degree. 3. A coaming plate is installed around the equipment, and the height is 600mm to prevent the sample from exploding or rupturing during the drop test. Splash of liquid and other contents may occur to prevent injury to the tester. 4. The control box is separated from the test instrument and can realize long-distance wired connection control, which plays a secondary protection role. 5. Drop the bottom plate: heavy, not easy to move during the test, the surface is flat and defect-free, the surface area can ensure that the package is completely dropped on the bottom plate 6. The device consists of an “E” fork that can be moved down quickly as a test piece holder. The test product is placed in balance according to the test requirements (face, edge, angle test). During the test, the arm moves down at a high speed, and the test product falls to the bottom plate glue with the “E" type fork, and is embedded in the bottom plate under the action of the high efficiency damper.

1. Flame-resistant and explosion-proof design of the test area The test area is composed of high temperature resistant and flame retardant parts (no plastic pipes, wires, rubber gaskets, seals, lubricating oil, engine oil, etc.) to prevent damage to the equipment caused by battery burning and explosion. 2. Anti-rust and corrosion-resistant design of the test area The surface of the steel frame in the test area is sprayed, and the guide rod is plated with hard chrome coating. It has high-strength, waterproof, rust-proof and corrosion-resistant design, so as to avoid the bad result of using...
