Description

Technical Field

[0001] The utility model relates to the technical field of automobile batteries, and particularly relates to an automobile battery life extension device. Background Art

[0002] At present, most fuel vehicles powered by gasoline use 12V batteries for power supply. Although there have been great improvements in the structural design and raw materials used in current vehicle-mounted batteries, the theoretical service life of maintenance-free lead-acid batteries in floating charge use is 15 - 20 years or more. However, in actual applications, the service life of lead-acid batteries often varies greatly from the theoretical life, and almost none can truly achieve it. The main reasons are as follows: When the vehicle starts each time, an impact current of several hundred amperes in an instant will cause invisible loss of the battery plates and accelerate the aging of the battery; overusing vehicle electrical appliances in a stationary state or over-discharging the battery due to long-term storage will greatly shorten the battery life; overcharging caused by too low or too high charging voltage will directly affect the service life of the battery. To solve the above problems, many vehicle-mounted battery life extension devices have been applied in current vehicles. However, the current battery life extension devices occupy a large space volume and there is no suitable installation space, and there is no suitable installation position in the engine compartment. For example, the Chinese utility model patent with the patent number 202320919839X discloses a device for extending the life of an automotive battery, including a battery body, a protective shell is sleeved on the top of the battery body, a cavity is formed inside the protective shell, and a capacitor life extension component is arranged in the cavity; the protective shell extends downward to form a left clamping plate, a rear heat insulation plate and a right heat insulation plate, the left clamping plate, the rear heat insulation plate, the right heat insulation plate and the protective shell are fixedly connected, the distance between the left clamping plate and the right heat insulation plate matches the length of the battery body, and the rear heat insulation plate and the right heat insulation plate respectively completely cover the rear side and the right side of the battery body. However, the capacitor life extension component is arranged on the top of the battery body, occupying a large space volume, unable to adapt to all vehicle types, and not conducive to its popularization. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automobile battery life extension device to solve the problems in the prior art that the automobile battery life extension device occupies a large volume and is not convenient for installation, as described in detail below.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A battery life extension device for an automobile provided by the utility model comprises a housing, a battery body, a capacitor bank and a control component arranged in the housing. The capacitor bank is arranged on one side of the battery body and arranged vertically. The volume of the housing is the same as that of the existing standard battery body, and the volume of the battery body is smaller than that of the existing standard battery body. The control component is electrically connected with the capacitor bank, and the capacitor bank is electrically connected with the battery body through the control component. The capacitor bank comprises at least six supercapacitors arranged vertically. The six supercapacitors are evenly divided into two groups. The three supercapacitors in each group are arranged side by side and connected in series end to end in sequence. The two groups of supercapacitors are arranged parallel to each other and arranged in a staggered manner. The two groups of supercapacitors are connected in series. Two electrode connection posts are arranged on the top of the housing. One of the electrode connection posts is connected with the positive electrode of the battery body and the positive electrode of the capacitor bank, and the other electrode connection post is connected with the negative electrode of the battery body and the negative electrode of the capacitor bank. The housing comprises an upper housing and a lower housing. The lower housing is of a cuboid structure. A battery slot and a capacitor slot are formed in the lower housing. The battery body is arranged in the battery slot, and the capacitor bank is arranged vertically in the capacitor slot.

[0006] The working process and principle of the above structure are as follows:

[0007] During production, the volume of the battery body is reduced, and then the battery body is placed in the battery slot of the lower housing, and the capacitor bank is placed in the capacitor slot, so that the battery body and the capacitor bank are both installed in the housing with the size of the existing battery body, thereby reducing the occupied volume of the life extension device and facilitating its direct installation in the engine compartment of the automobile. At the same time, the two groups of supercapacitors are arranged in a staggered manner, further reducing the occupied volume of the capacitor bank and solving the installation problem of the life extension device. During the daily operation of the automobile, the battery body charges the capacitor bank. When the automobile needs to start the engine, the control component enables the capacitor bank to release current, which can completely eliminate the large current impact on the vehicle-mounted battery when the automobile starts. After modification, the service life of the battery can be extended by about twice. At the same time, due to the strong filtering function of the capacitor bank, the engine starting of the automobile can be made more stable, and the acceleration and climbing performance can be significantly improved. The electrode connection posts can be quickly connected with the battery body and the capacitor bank, which is convenient for installation. The two groups of supercapacitors arranged in this way are beneficial to shortening the overall length and width of the housing and facilitating the installation of the device in the vehicle by utilizing the space inside the vehicle.

[0008] Further, the control component includes a circuit board, and an information processing module, a wireless communication device, an A / D acquisition device, and a relay disposed on the circuit board. The negative electrode of the capacitor bank is electrically connected to the negative electrode of the vehicle battery, and the positive electrode of the capacitor bank is electrically connected to the positive electrode of the battery body through the relay. The circuit board is electrically connected to the battery body, and the circuit board is connected in parallel with the capacitor bank. The signal input end of the relay is electrically connected to the signal output end of the information processing module. The first signal input end of the information processing module is electrically connected to the signal output end of the wireless communication device. The second signal input end of the information processing module is electrically connected to the signal output end of the A / D acquisition device.

[0009] The A / D acquisition device acquires the voltages of the user vehicle battery and the super capacitor, and feeds the acquired data back to the information processing module. The information processing module determines whether to connect the capacitor bank to the battery system of the user vehicle to release electric energy to assist in starting the vehicle by closing the relay according to the current vehicle battery voltage; or the data information can be uploaded to the background server through the wireless communication device, and the server determines whether to connect the capacitor bank to the battery system of the user vehicle to assist in starting according to the current vehicle battery voltage. After the vehicle starts successfully, the vehicle generator first charges the super capacitor, and then disconnects the relay after the charging is completed.

[0010] By setting the wireless communication device, the daily monitoring of the vehicle battery power can be realized. When the battery reaches a certain service life and is not replaced in time, the vehicle can be easily started by connecting the capacitor bank through the cooperation of the wireless communication device, the background server, and the user terminal. The development and implementation of this technology transform the previous rescue mode that requires on-site personnel to a remote operation mode, which can improve efficiency and reduce daily operating costs at the same time, and optimize the passive service mode to an active service mode, enhancing the quality of market application services.

[0011] Further, a first electrode plate is connected to the electrode connection post connecting the positive electrode of the battery body, and a second electrode plate is connected to the electrode connection post connecting the negative electrode of the battery body. Both ends of the first electrode plate are respectively connected to the positive electrode of the battery body and the positive electrode of the capacitor bank. One end of the second electrode plate is connected to the negative electrode of the battery body through one of the electrode connection posts, and the other end is connected to the negative electrode of the capacitor bank. The first electrode plate includes an electrode connection plate and a Z-shaped connection plate. One end of the electrode connection plate is connected to the electrode of the battery body, and the other end is connected to the Z-shaped connection plate through another electrode connection post. The other end of the Z-shaped connection plate is connected to the electrode of the capacitor bank. The second electrode plate is in a Z-shaped structure.

[0012] Due to the side-by-side arrangement of the battery body and the capacitor bank, it is inconvenient to connect the positive and negative electrodes of the battery body to the positive and negative electrodes of the capacitor bank. Therefore, the electrode connection plate is first connected to the positive electrode of the battery body, and is connected to the positive electrode of the capacitor bank through the electrode connection column and the Z-shaped connection plate. The battery body and the capacitor bank are connected to the negative electrode through the electrode connection column and the second electrode piece, eliminating the trouble of connecting the two.

[0013] Furthermore, the control component is arranged above the capacitor bank.

[0014] The control component is arranged above the capacitor bank, which is convenient for its connection with the capacitor bank and reduces the occupied volume space at the same time.

[0015] Furthermore, a shock-absorbing and heat-dissipating silica gel pad is arranged between the capacitor bank and the housing.

[0016] The setting of the shock-absorbing and heat-dissipating silica gel pad can not only support and stabilize the capacitor bank, but also play a role in shock absorption and buffering collision, and can also play a role in heat dissipation.

[0017] Furthermore, reinforcing ribs are formed on the outer side surface of the lower housing, a connecting strip is horizontally arranged at the bottom of the outer side surface of the lower housing, and screw holes are vertically formed in the connecting strip.

[0018] The setting of the reinforcing ribs ensures the strength of the lower housing and prevents it from deforming. The setting of the screw holes on the connecting strip facilitates the fixing of the housing.

[0019] Furthermore, a top block is arranged at the top of the upper housing, and the height of the top block is greater than the height of the electrode connection column.

[0020] The setting of the top block is beneficial to protecting the electrode connection column and preventing the electrode connection column from being pressed or worn.

[0021] The beneficial effects are as follows:

[0022] In the production of the present utility model, the volume of the battery body is reduced. Then, the battery body is placed in the battery slot of the lower housing, and the capacitor bank is placed in the capacitor slot, so that both the battery body and the capacitor bank are installed in a housing with the same size as the existing battery body, thereby reducing the occupied volume of the life extension device and facilitating its direct installation in the engine compartment of the vehicle. At the same time, the two sets of supercapacitors are arranged in a staggered manner, further reducing the occupied volume of the capacitor bank, solving the installation problem of the life extension device. During the daily operation of the vehicle, the battery body charges the capacitor bank. When the vehicle needs to start the engine, the control component enables the capacitor bank to release current, which can completely eliminate the large current impact on the vehicle-mounted battery when starting the vehicle. After modification, the service life of the battery can be extended by about one time. At the same time, due to the powerful filtering function of the capacitor bank, the vehicle can start more smoothly, significantly improving the acceleration and climbing performance. The electrode connection posts can quickly connect to the battery body and the capacitor bank, facilitating installation. The two sets of supercapacitors arranged in this way are beneficial to shortening the overall length and width of the housing and conveniently using the space inside the vehicle to install this device in the vehicle.

All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative efforts shall fall within the scope protected by the present utility model. Embodiment

[0032] See Figures 1-6 As shown, the present utility model provides an automobile battery life extension device, which includes a housing 1, and a battery body 5, a capacitor bank 2 and a control assembly 3 arranged in the housing 1.

The capacitor bank 2 includes at least six vertically arranged super capacitors 21. The six super capacitors 21 are evenly divided into two groups. The three super capacitors 21 in each group are arranged side by side and connected in series end to end in sequence. The two groups of super capacitors 21 are arranged parallel to each other and staggeredly. The two groups of super capacitors 21 are connected in series. Two electrode connection posts 6 are provided at the top of the housing 1. One of the electrode connection posts 6 is connected to the positive electrode of the battery body 5 and the positive electrode of the capacitor bank 2, and the other electrode connection post 6 is connected to the negative electrode of the battery body 5 and the negative electrode of the capacitor bank 2. The housing 1 includes an upper housing 111 and a lower housing 121. The lower housing 121 is of a cuboid structure. A battery slot 13 and a capacitor slot 14 are formed in the lower housing 121. The battery body 5 is arranged in the battery slot 13, and the capacitor bank 2 is vertically arranged in the capacitor slot 14.

[0033] The working process and principle of the above structure are as follows:

[0034] During production, the volume of the battery body is reduced. Then, the battery body is placed in the battery compartment 13 of the lower housing 121, and the capacitor bank 2 is placed in the capacitor compartment 14, so that both the battery body 5 and the capacitor bank 2 are installed in the housing 1 with the same size as the existing battery body 5, thereby reducing the volume occupied by the life extension device and facilitating its direct installation in the engine compartment of the vehicle. At the same time, the two sets of supercapacitors 21 are arranged in a staggered manner, further reducing the volume occupied by the capacitor bank 2 and solving the installation problem of the life extension device. During the daily operation of the vehicle, the battery body 5 charges the capacitor bank 2. When the vehicle needs to start, the control component 3 causes the capacitor bank 2 to release current, which can completely eliminate the large current impact on the vehicle-mounted battery during vehicle startup. After modification, the battery service life can be extended by about twice. At the same time, due to the powerful filtering function of the capacitor bank 2, the vehicle startup can be made more stable, significantly improving the acceleration and climbing performance; the electrode connection posts 6 can quickly connect to the battery body 5 and the capacitor bank 2, facilitating installation. The two sets of supercapacitors 21 arranged in this way are beneficial to shortening the overall length and width of the housing 1 and facilitating the installation of this device in the vehicle using the interior space of the vehicle.

[0036] The A / D acquisition device 34A / D acquires the voltage of the user vehicle battery and the voltage of the supercapacitor 21, and feeds the acquired data back to the information processing module 32. The information processing module 32 determines whether to connect the capacitor bank 2 to the battery system of the user vehicle to release electrical energy to assist vehicle startup by closing the relay 33 based on the current vehicle battery voltage; or the data information can be uploaded to the background server through the wireless communication device 35, and the server determines whether to connect the capacitor bank 2 to the battery system of the user vehicle to assist startup based on the current vehicle battery voltage; after the vehicle starts successfully, the vehicle generator first charges the supercapacitor 21, and after the charging is completed, the relay 33 is disconnected.

[0037] By setting up the wireless communication device 35, the daily monitoring of the vehicle battery power can be realized. When the battery has reached a certain service life and has not been replaced in time, the wireless communication device 35 can cooperate with the background server and the user terminal to remotely control the vehicle to be easily started by connecting the capacitor bank 2. The development and implementation of this technology transform the previous rescue mode that requires on-site personnel to a remote operation mode, which can improve efficiency while reducing daily operating costs, optimize the passive service mode to an active service mode, and enhance the quality of market application services.

[0039] Due to the side-by-side arrangement of the battery body 5 and the capacitor bank 2, it is inconvenient to connect the positive and negative electrodes of the battery body 5 to the positive and negative electrodes of the capacitor bank 2. Therefore, the electrode connection plate is first connected to the positive electrode of the battery body 5, and is connected to the positive electrode of the capacitor bank 2 through the electrode connection column 6 and the Z-shaped connection plate.

[0046] In another embodiment of the present invention, as Figures 1-6 shown, a top block 7 is provided at the top of the upper housing 111, and the height of the top block 7 is greater than the height of the electrode connecting post 6.

[0047] The arrangement of the top block 7 is beneficial to protecting the electrode connecting post 6 and preventing the electrode connecting post 6 from being pressed or worn.

[0048] The rest of the structure and working principle of this embodiment are the same as those of Embodiment 1.
