Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0017] The present invention has the embodiment of the lithium battery pack of warning function: as Figure 1-Figure 4 As shown, the lithium battery pack with alarm function includes a box body, a plurality of battery cells 1 arranged in the box body, and an alarm module. The box body includes a box body, a lower support plate 3, and an upper cover plate. The battery cell is a cylindrical battery, and the battery cell has a positive pole and a negative pole respectively at two ends. The battery cells are sequentially connected in series, and the battery cells are distributed in a rectangular shape.

[0018] The positive poles and negative poles of two adjacent battery cells are connected through a conductive plate. The distribution mode of each conductive plate is S-shaped, ...

Abstract

The invention relates to a lithium battery pack with alarm function, the battery pack includes a housing, a plurality of battery cells arranged in the cabinet, Alarm module, A battery cell is a cylindrical battery, the positive electrode of two adjacent cells, As that negative electrode are connected with each other through the conductive plate, the battery cells are spaced apart from each other,A left side plate in that cabinet body, the right side plate is provided with ventilation holes, the left side plate is provided with a heat dissipation fan, and more than two temperature sensors distributed in different areas are arranged in the cabinet body, the temperature sensors feedback the detected temperature value to the controller, and when the temperature value reaches a set first temperature threshold, the controller controls the heat dissipation fan to start; The controller controls the alarm module to alarm when the temperature value exceeds the set second threshold. The batterypack of the invention can detect the internal temperature of the box body in real time, make different responses according to the temperature value, and ensure the use safety of the battery.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery pack with an alarm function. Background technique [0002] Lithium batteries have the advantages of less environmental pollution, no noise, and high energy ratio. There are more and more applications, such as power batteries, used in electric bicycles and electric vehicles. The battery cells of the battery pack mainly have two types of hard shell packaging and soft shell packaging. According to different power and voltage requirements, multiple battery cells are combined in series and parallel. As the power source of electric vehicles, a certain number of lithium batteries are connected in series and parallel to form a high-power and large-capacity lithium battery pack. During the charging and discharging process of the lithium battery, the battery itself and the components on the high-current path will generate heat, causing the temperature in the ba...
