Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of detection devices, and particularly relates to a new energy automobile battery performance detection device. BACKGROUND

[0002] As the power source of new energy automobiles, power batteries are the most important system in the whole vehicle, accounting for 30% to 40% of the cost of the whole vehicle, which is also a landmark component distinguishing from other traditional fuel vehicles. The heart of a traditional fuel vehicle is an engine, and the heart of a new energy automobile is a power battery.

[0003] In response to the urban number limit policy, the intention of Chinese car buyers to purchase pure electric vehicles is becoming higher and higher. New energy vehicles are different from traditional internal combustion engine vehicles. A traditional fuel vehicle has three major components, namely an engine, a transmission and a chassis, which determine the performance and quality of a vehicle. Today's pure electric vehicles also have three major components, namely the "three electric systems", which are power batteries, electric drive systems and electric control systems. Among them, the power battery is the part that consumers pay most attention to, which directly determines the vehicle's range. The quality, safety, performance and reliability of the power battery are directly related to the use experience of the pure electric vehicle. Especially since this year, the frequent occurrence of spontaneous combustion events has made the power battery a hot topic of discussion on spontaneous combustion events.

[0004] A battery assembly performance detection test device is provided in CN111974710A, which includes a base, a feeding mechanism, a moving mechanism, a compression resistance detection mechanism, a limiting mechanism, a fixed baffle and a second bracket. The front and rear sides of the rotating frame are provided with collection boxes. The moving mechanism is arranged on the top of the first bearing table and the top of the second bearing table. The moving sleeve is slidingly connected to the top of the first bearing table and the top of the second bearing table. The compression resistance detection mechanism is fixed to the inner top of the bearing frame. The limiting mechanism is fixed to the inner top of the bearing frame. The second bracket is fixed to the base. The bearing box is located on the right side of the second bearing table, and a second opening is formed on the left side of the second bearing table. After the feeding operation is completed, the limiting plate can move forward and backward together with the moving sleeve and approach each other, which facilitates the limiting of the battery assembly. Then the top pressing block moves downward, facilitating the compression resistance test of the battery assembly. When the battery is actually subjected to puncture, impact and compression resistance test, the battery will leak liquid under external force impact, even produce smoke, further cause spontaneous combustion or explosion. It is difficult to set a structure to wrap around the outer edge of the detection device, difficult to fix, and the joint fixing part is easy to deform under heat, difficult to open. SUMMARY
