Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to an integrated lithium battery power supply. Background Technology

[0002] A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Currently, the parallel lithium battery module announced in Chinese Patent No. CN103326075B is composed of multiple lithium battery modules with the same nominal voltage connected in parallel. Each lithium battery module is formed by connecting two or more lithium batteries in series. Each series battery in the lithium battery module is connected to a voltage sampling line. Each voltage sampling line is connected in series with a recoverable current-limiting temperature control element. The corresponding voltage sampling lines on each series battery with the same potential in each lithium battery module are connected in parallel.

[0003] However, integrated lithium battery power supplies require multiple lithium batteries to be connected sequentially. However, the lack of positioning and guiding mechanisms when installing multiple lithium batteries affects their stability. Furthermore, the heat generated by multiple lithium batteries is difficult to dissipate, posing a safety hazard. Therefore, we propose an integrated lithium battery power supply to solve the above problems. Utility Model Content

The heat dissipation plate is fixedly installed on both the front and rear sides of the lower housing, and the heat dissipation plate is fixedly connected to the heat conduction plate. Multiple heat dissipation fins are installed at equal intervals on one side of the heat dissipation plate.

[0012] Preferably, two mounting plates are fixedly installed on both sides of the lower housing, and the mounting plates are provided with mounting mechanisms for fixing the power supply body.

[0013] Preferably, the mounting mechanism includes a mounting hole and a fixing bolt, wherein the mounting hole is formed on the top of the mounting plate and the fixing bolt is installed in the mounting hole.

[0014] The beneficial effects of this utility model are:
