With the continuous development of society and the vigorous promotion of the country, new energy automobiles have gone into thousands of households. The new energy automobile accelerates to catch up with the fuel automobile by the clean charging and discharging mode and the use characteristics of the new energy automobile, and the market of users of the new energy automobile is continuously expanded. Meanwhile, a core component of the new energy automobile, namely, the related characteristics of the new energy automobile battery, are also widely concerned, and in view of frequent fire accidents of the new energy automobile in various places in the beginning of the year, the safety of the new energy automobile battery is more concerned by enterprises and society, and the soft package battery is taken as one of the new energy automobile batteries, and the safety of the soft package battery is also concerned by various places.
The heat generation factors in the new energy automobile battery are many, and the heat generation quantity is increased sharply under the abuse condition, wherein the needle prick is a serious abuse condition. The battery needling mechanism is complex, but different battery mechanisms are similar, such as lithium ion batteries, when the battery is punctured by the pricking pin, a plurality of electrode units are punctured, and all the punctured electrode units participate in discharging. Due to the error of the punctured position of the battery and the slight deviation of the battery manufacturing process, the puncture needle and the damaged electrode unit generate different random contact interfaces, and the random interfaces also influence the discharge effect of the electrode unit and the resistance of the contact interfaces. When the battery is subjected to the needle punching, particles inside the battery can migrate. The short circuit state is equivalent to between the positive and negative current collectors in the battery, and large current is generated instantly and flows from the positive current collector to the negative current collector through the puncture needle. Li+The lithium is extracted from the lithium structure inserted into the negative electrode, enters the electrolyte, and migrates to the positive electrode through the separator. After the battery is punctured, the contact interface affects the internal discharge condition of the battery, and if the puncturing needle is in good contact with the electrode units, the electrode units participate in short-circuit discharge, and the heat generation amount is large. If the pricker is only contacted with a few electrode units, the electrode units participate in discharging in a relatively small quantity, the generated heat is relatively less, and the severe thermal runaway reaction of the battery is relatively mild.
At present, a plurality of battery clamps have been researched and developed by a plurality of units, but a practical clamp has not yet been designed to the acupuncture experiment, and is blank in the aspect of the acupuncture experiment clamp of laminate polymer battery especially. Therefore, the related safety experiment of the battery is performed in a clamping manner no matter in related scientific research institutions or related enterprises, wherein the acupuncture experiment is one of important links, and therefore, a simple and practical battery clamp is very important.
