[0002] Green and environmentally friendly batteries refer to a type of high-performance, pollution-free battery that has been put into use or is under research and development. This category includes widely used nickel-metal hydride batteries and lithium-ion batteries, as well as mercury-free alkaline zinc-manganese primary batteries and rechargeable batteries that are being promoted, and lithium or lithium-ion batteries and fuel cells that are under research and development. Generally, batteries at high temperatures pose an explosion risk. Of all battery performance characteristics, safety is paramount. Overcharging or other factors that cause batteries to overheat can harm the user's personal safety.

[0003] Existing battery testing equipment is expensive, and battery mounting is cumbersome, causing significant inconvenience to users. In computer room environments, because battery packs power numerous devices, once a battery pack enters an external discharge state, the battery will generate substantial heat through the large current, increasing the risk of equipment or wiring damage, and sometimes even explosion. The temperature of the battery pack during discharge is a crucial indicator of its condition, but due to a lack of continuous observation and recording, it is difficult to detect hidden problems within the battery pack, such as degradation and aging.

[0004] Based on the above problems, developing a battery overcharge device capable of real-time monitoring of battery operating status and effectively ensuring the safety of test personnel is of significant technical importance and application value, and is also a problem that needs to be solved in the existing technology. To avoid equipment damage and personnel injury caused by heat accumulation during battery discharge, those skilled in the art have provided a lithium-ion battery overcharge device with monitoring functions.

[0006] To achieve the above objectives, this utility model provides a lithium-ion battery overcharge device with monitoring function, including a safety housing, a battery assembly, a current and voltage monitor, and a monitoring imaging module.

[0007] Preferably, the top of the safety enclosure is provided with a fan for heat dissipation, the front end of the safety enclosure is provided with a door panel, one side of the door panel is connected to the safety enclosure by a hinge, the other side is provided with a handle door lock, and the door panel is provided with a first observation window relative to the position of the current and voltage monitor.

[0008] Preferably, a second observation window is provided in the middle of the door panel, the monitoring imaging module is fixedly connected to the second observation window, a protective plate is provided on the inner wall of the second observation window, and a protective cover is provided on its outer wall.

[0009] Preferably, both the first observation window and the protective plate are made of transparent tempered glass.

[0011] Preferably, the middle partition divides the safety enclosure into a double-layer structure, and the middle partition is provided with elongated holes arranged at equal intervals.

[0012] Therefore, the lithium-ion battery overcharge device with monitoring function that adopts the above-described structure has the following advantages compared with the prior art:
