The invention relates to the technical field of battery testing equipment, in particular to a multifunctional lithium battery anti-explosion testing machine. The multifunctional lithium battery anti-explosion testing machine comprises a testing machine body, a high-pressure gas tank and an audible and visual alarm are arranged on the surface of the testing machine body, an external terminal is arranged on the right side surface of the testing machine body in an embedding mode, and an experiment door is hinged to the front surface of the testing machine body; and an experiment hollow cavity isformed in the surface of the testing machine body, an internal terminal is arranged on the inner wall of the right side of the experiment hollow cavity in an embedding mode, a plurality of gas exhausting ports are formed in the inner wall of the rear side of the experiment hollow cavity, a smoke discharging fan is arranged on the rear side of the gas exhausting ports, and a smoke discharging window is arranged on the rear side of the smoke discharging fan. According to the multifunctional lithium battery anti-explosion testing machine, an experiment lithium battery communicates with a power source to perform a charging and discharging experiment, when the experiment lithium battery explodes, the pressure in the experiment hollow cavity is increased, a pressure sensor reacts, the internal terminal and the external terminal are disconnected through guiding wires, meanwhile, the audible and visual alarm gives the alarm, an electromagnetic valve opens, and the smoke discharging fan rotates; and the operation is easy, and popularization and generalization are facilitated.
Description
technical field [0001] The invention relates to the technical field of battery testing equipment, in particular to a multifunctional lithium battery explosion-proof testing machine. Background technique [0002] Lithium batteries are now widely used in mobile phones, toys, electric bicycles or other daily necessities. my country is a major country in the production and sales of rechargeable batteries, with a huge export volume. According to the requirements of GB / T18287 and other standards, it is necessary to conduct high-current charge and discharge tests on rechargeable batteries. [0003] In the previous test process, battery explosion and fire accidents occurred many times, which seriously threatened the safety of test personnel and test equipment, and most of the test machines can only extinguish fire, and cannot provide sound and light reminders. In view of this, we propose a Multifunctional lithium battery explosion-proof testing machine. Contents of the invention ...
