Automatic charging power-off protection equipment for lithium battery

Abstract

The invention discloses automatic charging power-off protection equipment for a lithium batteryand belongs to the field of lithium batteries. Theequipment comprises a shell; the inner wall of the shell is fixedly connected with a charging groove; the charging groove is internally provided with a lithium battery; the inner wall of the shell is fixedly connected with a motor; the output end of the motor is fixedly connected with a rotating shaft; one end of the rotating shaft is fixedly connected with a driving gear; and the bottom of the driving gear is meshed with a driven gear. According to the equipment, the motor, the rotating shaft, the driving gear, the driven gear, a screw rod, a threaded cylinder, a connecting plate and heat dissipation plate sheets are arranged, the motor drives the driving gear on the rotating shaft to rotate and drives the screw rod to rotate when working, the threaded cylinder is driven to move leftwards when the screw rod rotates, and then the heat dissipation plate sheets on the connecting plate are driven to move leftwards; and when the heat dissipation plate sheets move to the position above the lithium battery, the heat dissipation plate sheets can play a role in heat dissipation of the lithium battery, so that safety accidents are influence on the service life of the lithium battery due to the fact that the situation that the temperature of the lithium battery is too high during charging are avoided.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a lithium battery automatic charging and power-off protection device. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific capacity, self-discharge rate and performance-price ratio are superior t...

Problems solved by technology

[0003] Lithium battery chargers in the prior art, when charging the lithium battery, the lithium battery is prone to heating during the charging process. If the temperature is not lowered in time, it is easy to cause accidents. In addition, the prior art When charging the lithium battery in the battery, the user is usually reminded that the charging is complete through the color change of the indicator light, but the user cannot pay attention to the color of the indicator light in time, and cannot cut off the power of the lithium battery in time, which will easily cause the service life of the lithium battery to decrease.
