Description

Technical Field

[0001] The utility model relates to a lithium battery pack with a warning function, belonging to the technical field of lithium battery packs. Background Technique

[0002] A lithium battery is a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. After lithium ions gain electrons, lithium atom crystals will form on the material surface, which is the same as overcharging and will cause danger. In case the battery shell cracks, it will explode. Therefore, the protection of lithium-ion batteries should at least include three items: the upper limit of charging voltage, the lower limit of discharging voltage, and the upper limit of current. Generally, in a lithium battery pack, in addition to the lithium battery cells, there will be a protection board, which mainly provides these three protections.

[0003] After retrieval, it is found that for a lithium battery pack with a warning function described in the authorized publication number CN219610534U, its beneficial effects are as follows: 1. In the utility model, by installing a motor, the temperature inside the covered shell can be monitored through the operation of the temperature sensor. The control component is electrically connected to the temperature sensor, and the control component can process the temperature data monitored by the temperature sensor. When it is detected that the temperature inside the shell is too high, the control component can control the motor to operate. The motor generates kinetic energy and supplies it to the output fan blade. The fan blade rotates through the kinetic energy provided by the motor, driving the air to flow faster. The high temperature generated during the use of the battery body flows through the through holes and is discharged through the ventilation net, thereby realizing the monitoring and warning of the heat generated during the charging and discharging processes of the lithium battery pack during use, quickly extracting and cooling the generated high temperature, and effectively improving the installation safety during the use of the lithium battery pack. 2. In the utility model, by installing a limiting plate, by rotating the threaded nut, the threaded rod can rotate inside the shell. Through the engagement plate being penetrated and meshed with the threaded rod, when the threaded rod rotates, the use position of the limiting plate can be adjusted. The contact block is an elastic material rectangular block with a certain thickness. By contacting the battery body with the contact block, due to the thickness of the contact block, there is a certain distance between the battery body and the limiting plate, which is convenient for the battery body to dissipate heat. By adjusting the distances of each limiting plate, the battery bodies inside the shell are squeezed and limited, thereby realizing the quick adjustment and limiting installation of the battery bodies. The limiting plate can buffer and protect the battery body when it is impacted, and due to the thickness of the contact block itself, there is a certain space between the battery body and the limiting plate, which can assist the battery body in dissipating heat and increase the heat dissipation performance of the lithium battery pack.

[0004] However, first of all, when it dissipates heat from the battery, it uses the rotation of the fan blades to suck the hot air downward and discharge it. Since the hot air has a small density and will float upward, the heat dissipation performance will be poor. Secondly, especially in hot weather, when only cooling by the fan blades, the effect is not obvious, and the use defects are relatively obvious and need to be improved urgently. Therefore, a lithium battery pack with a warning function is needed for people to use. Summary of the Invention

[0005] The purpose of the present invention is to provide a lithium battery pack with a warning function. When in use, the temperature sensor can be used to monitor the battery temperature in real time. When the temperature is too high, the cooling fan and the submersible pump work at the same time. The cooling fan discharges the originally rising hot air more quickly through the cooling filter screen. And the submersible pump extracts the coolant and circulates it through the meandering heat conduction pipe for heat conduction and cooling, so as to improve the efficiency of battery cooling and heat dissipation, and greatly ensure the stability and safety of lithium battery use. In addition, through the action of the movable partition and the protective plate, the batteries do not directly contact each other, and a gap is ensured between the battery and the partition, which is conducive to the progress of the cooling and heat dissipation work, and the position of the movable partition can be adjusted by rotating the adjusting bolt, which is conducive to installing and fixing batteries of different sizes for use, so as to solve the problems raised in the above background technology.
