Description

Technical Field

[0001] This utility model belongs to the field of storage battery technology, specifically relating to a storage battery with a detection chip. Background Technology

[0002] The internal components of a lead-acid battery that store and release electrical energy are the battery plates. A certain thickness of lead paste is coated on the plates to participate in the chemical reaction. Current is collected through the grid and conducted from the tabs to the busbars, and then to the external terminals of the battery. Battery tabs are divided into two types: edge tabs and center tabs. Center tabs are beneficial for improving the uniformity of current density distribution on the plates and reducing plate voltage drop, thus improving the battery's high-current discharge capability. Therefore, the tabs are positioned as centrally as possible. However, due to the special structure of lead-acid batteries, there is usually an acid filling hole between the positive and negative tabs, which limits the center-to-center distance between the tabs and, consequently, the center-to-center distance between the grid tabs.

[0003] For example, utility model patent CN219801079U discloses a battery cover, including a cover body. Several safety valve slots are arranged in a row on the top surface of the cover body. Each safety valve slot has an acid injection hole on its bottom surface, with an acid injection hole in the middle of the hole. The safety valve slots also have busbars on both sides along the width of the battery cover for accommodating lead-acid battery busbars. In this utility model, the bottom slot for the acid injection hole is located between two busbars, which restricts the distance between the two busbars, thus affecting the battery's discharge performance and corrosion resistance. Furthermore, there is no extra space on the top of the battery cover to place other effective controls.

[0004] Lead-acid batteries often experience temperature increases during charging and discharging due to excessive load. If this heat is not dissipated promptly, it can cause the battery to bulge and, in severe cases, damage it. Therefore, temperature monitoring of lead-acid batteries is crucial. Existing monitoring devices are generally independent of the lead-acid battery and cannot provide real-time or remote monitoring. Adding temperature monitoring components to the lead-acid battery may increase its size or, without changing the battery size, reduce the size of the plates, thus decreasing the battery capacity. Utility Model Content

[0005] To address the aforementioned technical problems in the existing technology, this utility model provides a battery with a detection chip. By adding a detection chip to the battery cover with the acid filling hole offset, real-time acquisition of battery temperature data can be achieved.

[0006] This utility model provides a battery with a detection chip, including a battery case and a battery cover that fit together. The battery case is divided into multiple cells, and each cell has a group of electrodes. The group of electrodes includes alternating positive and negative plates, with a partition between adjacent positive and negative plates. Each positive plate has a positive tab, and each negative plate has a negative tab. In the same group of electrodes, the positive tabs face the same end, and the negative tabs face the opposite end. Both the positive and negative tabs are located in the middle of one side of the positive or negative plate. The positive tabs at the same end in each group of electrodes are connected by a positive busbar, and the negative tabs at the same end in each group of electrodes are connected by a negative busbar. The positive and negative tabs of adjacent groups of electrodes face opposite directions, and there is a connection between adjacent groups of electrodes. The positive and negative busbars are connected in series. A positive terminal post and a negative terminal post are respectively provided on a positive busbar and a negative busbar located at the beginning and end of the top surface of the lead-acid battery. Terminal holes are provided at both ends of the battery cover along its length. A cover plate groove is provided on the top surface of the battery cover, and a cover plate is fitted on the cover plate groove. The cover plate groove includes a first groove located on one side of the battery cover and a second groove located on the other side of the battery cover and between the two end sub-holes. Each cell in the first groove is provided with an acid injection hole post for acid injection. Each cell is provided with a temperature sensor. Each temperature sensor is connected to a PCB board located in the second groove through a transmission line. The PCB board is used to receive the temperature signal detected by the temperature sensor and transmit it to the client.

[0007] Furthermore, the PCB board is bonded to the bottom surface of the second groove with adhesive or double-sided tape, and the top surface of the PCB board is provided with support points for supporting the cover plate. The installation and fixing of the PCB board is very simple.

[0008] Furthermore, the second tank has a mounting hole on the side near the acid injection column for the transmission line to extend out. During assembly, the temperature sensor is inserted into the top of each cell, and the mounting hole is sealed with resin glue.

[0009] Furthermore, the top surface of the battery cover has an installation channel between the area where the terminal hole is located and the second groove; the battery also includes a handle, the two ends of which extend into two installation channels on both sides of the second groove. The side wall of the second groove is provided with a circular installation hole, and the two ends of the handle are correspondingly provided with installation protrusions extending into the circular installation holes. Existing power battery packs are installed in limited space, resulting in small gaps between the battery packs after installation, making later removal difficult. Due to the presence of the acid filling hole, it is impossible to install a handle in the middle of the existing power battery pack. This utility model increases the effective space by offsetting the acid filling hole, and by adding a battery handle on this basis, it solves the problem of difficult battery pack removal.

[0010] Furthermore, the mounting channel extends to the side of the battery cover away from the acid injection hole post and opens on that side, allowing the handle to be folded down when not in use.

[0011] Furthermore, the handle has a U-shaped structure, including two arms and a handle portion connecting the two arms; the second groove body is recessed on the top surface of the battery cover on the side opposite to the acid injection hole post, thereby forming a stepped structure for placing the handle portion; when the handle is stored, the two arms are respectively located in the installation channel, and the handle portion is located on the stepped structure.

[0012] Furthermore, the bottom surface of the battery compartment is also open and fitted with a sealing cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) A detection chip was added to the lead-acid battery. Temperature data of each electrode group was collected by the temperature sensor. The chip collected the temperature data into the memory and then transmitted it to the client to realize real-time acquisition and remote monitoring of battery temperature data.

[0015] (2) Although a smart detection chip was added to the lead-acid battery, it did not affect the size of the lead-acid battery itself.

[0016] (3) The upper and lower busbars of the battery are placed in different positions to prevent the tabs from interfering with each other. This allows the tabs to be placed in the middle of the battery plates, solving the problem of current concentration on the battery plates and improving the discharge performance of the battery and the corrosion resistance of the battery plates.

Detailed Implementation

[0023] like Figures 1-4 As shown, this embodiment provides a battery with a detection chip, including a battery case 1 and a battery cover 2 that are fitted together. The battery case 1 is divided into multiple individual cells, each individual cell having a group of electrodes. The group of electrodes includes positive and negative electrodes that are stacked alternately. There is a partition between adjacent positive and negative electrodes. Each positive electrode has a positive tab, and each negative electrode has a negative tab.

[0024] In the same electrode group, all positive tabs face the same end, and all negative tabs face the opposite end, with both positive and negative tabs located in the middle of one side of the positive or negative electrode plate. Positive tabs located at the same end in each electrode group are connected using a positive busbar, and negative tabs located at the same end in each electrode group are connected using a negative busbar.

[0025] The positive and negative tabs of adjacent electrode groups face opposite directions. For example, in one electrode group, the positive tab faces upward and the negative tab faces downward, while in the adjacent electrode group, the positive tab faces downward and the negative tab faces upward. Adjacent electrode groups are connected in series by a positive bus and a negative bus. A positive terminal and a negative terminal are respectively provided on a positive bus and a negative bus located at the beginning and end of the top surface of the lead-acid battery. Terminal holes 3 are provided at both ends of the battery cover 2 along its length.

[0026] The top surface of the battery cover 2 is provided with a cover plate groove 4, and a cover plate 5 is fitted on the cover plate groove 4. The cover plate groove 4 includes a first groove 41 located on one side of the battery cover 2 and a second groove 42 located on the other side of the battery cover 2 and between the two end holes 3. Each cell in the first groove 41 is provided with an acid injection hole post 43 for acid injection.

[0027] The bottom of the battery compartment 1 is also open, and is fitted with a lower cover 6 for sealing.

[0028] Each compartment contains a temperature sensor, which is connected to a PCB board 44 located in the second tank 42 via a transmission line 46. The PCB board 44 receives the temperature signals detected by the temperature sensors and transmits them to the client. The PCB board 44 is easily fixed to the bottom surface of the second tank 42 using glue or double-sided adhesive. The top surface of the PCB board 44 has support points 45 for supporting the cover plate 5.

[0029] The second tank 42 has a mounting hole on the side near the acid injection hole column 43 for the transmission line 46 to extend out. During assembly, the temperature sensor is inserted into the top of each cell, and the mounting hole is sealed with resin glue.

[0030] The battery also includes a handle 7, which solves the problem of difficulty in removing the battery pack. The top surface of the battery cover 2 has an installation channel 71 between the area where the terminal hole 3 is located and the second groove 42. Both ends of the handle 7 extend into the two installation channels 71 on both sides of the second groove 42. The side wall of the second groove 42 is provided with a circular installation hole 72, and both ends of the handle 7 are provided with corresponding installation protrusions 73 that extend into the circular installation holes 72.

[0031] The mounting channel 71 extends to the side of the battery cover 2 on the side opposite to the acid injection hole column 43 and opens on that side.

[0032] The handle 7 has a U-shaped structure, including two arms and a handle portion 74 connecting the two arms. To facilitate the storage of the handle 7, the second groove 42 is recessed on the top surface of the battery cover 2 on the side opposite to the acid injection hole post 43, thus forming a stepped structure for placing the handle portion 74. When the handle 7 is stored, the two arms are located in the mounting channel 71, and the handle portion 74 is located on the stepped structure.

[0033] This utility model relates to a battery with a detection chip. The upper and lower busbars are placed in different positions to prevent interference between the tabs. This allows the tabs to be positioned in the center of the battery plates. Without affecting the size of the lead-acid battery itself, the addition of a detection chip and a temperature sensor is achieved. The temperature sensor collects temperature data from each group of electrodes, and the detection chip collects the collected temperature data into a memory and then transmits it to the client, realizing real-time acquisition and remote monitoring of battery temperature data.
