Description
Technical Field
The invention relates to the field of battery boxes, in particular to a battery box.
Background
Currently, lithium batteries are a type of batteries using a nonaqueous electrolyte solution, which uses lithium metal or a lithium alloy as a negative electrode material. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium in the metallic state and are rechargeable.
Lithium batteries are generally not easily exploded, but in some special cases, the explosion probability of lithium batteries is increased. The reason for explosion of the lithium battery is as follows: 1) The water content is too large: when in charging, water can react with lithium to generate lithium oxide, which can cause capacity loss of the battery cell, and the battery cell is easy to be overcharged, so that gas is generated. The decomposition of water lowers the voltage and is likely to decompose into gas during charging. The series of generated gases can increase the internal pressure of the battery cell, and when the shell of the battery cell is not born, the battery cell can explode. 2) Internal short circuit: the internal cell is short-circuited to cause large-current discharge, a large amount of heat is generated, a diaphragm is burnt out, a larger short-circuit phenomenon is caused, electrolyte is decomposed into gas, and the internal pressure is excessively high, so that the cell explosion is caused. 3) And (3) overcharging a lithium battery: when the battery cell is overcharged, the structure of the positive electrode can be changed by excessive lithium released from the positive electrode, the excessive lithium cannot be easily inserted into the negative electrode, and lithium precipitation on the surface of the negative electrode is easily caused. When the voltage reaches above 4.5V, the electrolyte can decompose to generate a large amount of gas, and explosion is caused. Thus, explosion of the lithium battery can be early warned in advance by detecting the internal air pressure. Moreover, the existing battery box cannot early warn the internal air pressure of the box body in advance, and further cannot accurately predict the risk of explosion of the lithium battery.

1. According to the invention, the lower air guide cavity is communicated with the box body, the piston is pushed to move upwards by the air pressure rise in the box body, so that the conductive part of the spindle body is inserted into the air bubble, the resistance of the circuit communicated with the first conductive sheet, the conductive liquid, the second conductive sheet and the ammeter is changed (namely, the resistance value is increased, the current value in the ammeter is reduced), and the current value is the minimum at the moment, so that the control unit can accurately early warn the air pressure rise in the box body rapidly in advance, and further accurately predict the risk of explosion of the lithium battery.
2.
