Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle battery management, and in particular to an intelligent new energy vehicle battery management device and management method. Background Art

[0002] In the field of new energy vehicle energy supply, most new energy vehicles are currently powered by electricity, that is, electric vehicles. Such new energy vehicles use a collection of battery packs as energy storage and a source of power for vehicle travel. At present, battery management of electric vehicles is a top priority. Current electric vehicles are also equipped with a battery management system (BMS), which needs to monitor key parameters such as the voltage, current and internal resistance of each single cell in the battery pack, the battery's charge, health status and power status, the battery's charge and discharge management, and the battery's thermal management in various usage states.

[0003] The thermal management of batteries is also related to vehicle safety, battery life and battery charging and discharging efficiency. Most electric vehicles are currently equipped with built-in thermal management devices that can control the battery temperature inside the battery pack. At the current stage, during the charging process of electric vehicles, the environment in which the vehicle is located still greatly affects the charging efficiency of the battery. Under the influence of low temperature weather, the low temperature reduces the activity of the battery and slows down the charging speed of the battery itself. The battery management system will also control the activation of the vehicle's thermal management system, and the charging power will also be limited for safety reasons. High temperature weather will also cause the performance of the battery to decline, accelerate the reaction inside the battery and accelerate the aging process. The battery management system will also control the activation of the vehicle's thermal management system, and the charging power will also be limited for safety reasons. C system; and at present, outdoor charging piles and their computer modules cannot solve the above problems. More car owners also choose to charge their electric vehicles at night. During the summer nights, the charging of electric vehicles is less affected by the ambient temperature, but during the winter day, the charging of electric vehicles is greatly affected by the environment; during the summer daytime, the outdoor charging parking spaces are exposed to high temperatures and the surrounding ambient temperature is also high, so electric vehicles are greatly affected by the environment; due to the above-mentioned factors affecting the charging of electric vehicles due to the external environment, the charging speed of the battery pack of the electric vehicle will be reduced, and the battery life will be affected, and a thermal management system is required to control the charging temperature of the battery pack. However, the thermal management system needs to occupy a part of the charging power during operation, which indirectly leads to an extension of the overall charging time.

[0004] Therefore, it is necessary to develop an intelligent new energy vehicle battery management device and management method for temperature management of electric vehicles during charging to solve the above problems. Summary of the Invention

Drive the vehicle into the charging parking space where the intelligent new energy vehicle battery management device is installed, and connect the charging head of the vehicle to the charging terminal through the charging pile and its computer module; S2. The battery management system of the vehicle battery pack communicates data with the charging station and its computer module to identify relevant data of the vehicle battery pack, such as battery health, total and remaining battery capacity, and battery temperature. This allows the charging station and its computer module to calculate a battery charging management plan with appropriate charging power and charging temperature.

[0016] Beneficial effects of the present invention: 1. The present invention adopts a method of building an independent space by adopting a front beam, a middle beam, a rear beam, a foldable thermal insulation layer and the lower side of the battery pack, which can not only isolate the vehicle battery pack from the external low-temperature or high-temperature air during the charging process, but also can control the temperature of the independent space through the temperature control mechanism, so that the battery pack can be in an environment with a suitable charging temperature range, and does not require the built-in thermal management system of the vehicle battery pack to occupy too much charging power to work, thereby ensuring that the battery pack can have full charging power, and the foldable thermal insulation layer can reduce the temperature loss rate in the independent space, reduce the operating power of the temperature control mechanism, and reduce energy consumption.

[0017] 2. The present invention achieves flexible lifting by adopting a folding airbag inflation method to lift the rear beam, middle beam, front beam and foldable insulation layer to contact the lower side of the battery pack, so that the rear beam, middle beam, front beam and foldable insulation layer will not mechanically directly and rigidly contact the lower side of the battery pack, thereby protecting the lower side of the battery pack from mechanical damage.

[0018] 3. The present invention adopts a pull-back mechanism to fold and shrink the front beam, middle beam, rear beam and foldable thermal insulation layer, which can facilitate the storage of the front beam, middle beam, rear beam and foldable thermal insulation layer in the attitude adjustment cabin. This can reduce the occupied area of the smart new energy vehicle battery management device, and after storage, the device can be withdrawn from the parking space to avoid damage caused by crushing when the vehicle enters or exits. It can also prevent environmental debris from falling into the space between the front beam, middle beam, rear beam and foldable thermal insulation layer, avoiding frequent cleaning of the space between the front beam, middle beam, rear beam and foldable thermal insulation layer.

[0019] 4. The present invention adopts a method of storing the front beam, middle beam, rear beam and foldable thermal insulation layer into the attitude adjustment cabin, and cooperates with the attitude adjustment motor and electric slide rail of the attitude adjustment mechanism. Therefore, the attitude adjustment cabin can adapt to the parking position of the vehicle regardless of the attitude when the vehicle enters the parking space, so that the front beam, middle beam, rear beam and foldable thermal insulation layer can all be accurately positioned within the lower side of the vehicle battery pack.

The rear connecting pipe 154 is connected to the left end of the rear spiral air pipe 152 and is in communication with each other. The front connecting pipe 154 is connected to the left end of the front spiral air pipe 152 and is in communication with each other.

[0043] like Figure 2As shown, it also includes a camera 16, and there are four cameras 16. The cameras 16 are fixedly connected to the front and rear positions of the left side wall of the front beam 7 and the right side wall of the rear beam 9 respectively. The cameras 16 are used to accurately determine the position of the front beam 7 and the rear beam 9 at the bottom of the vehicle. The images of the four cameras 16 can be displayed in real time on the rotating display 4. The owner can accurately determine the position of the front beam 7 and the rear beam 9 on the lower side of the vehicle battery pack based on the image display, so that the front beam 7, the middle beam 8 and the rear beam 9 can accurately cover the battery pack, avoiding uneven temperature control caused by missing coverage of a certain area, or avoiding the coverage range exceeding the battery pack to make the coverage space too large, so that a larger unnecessary power of the hot and cold ventilation unit 153 is required, so that the operating power of the temperature control mechanism 15 can work reasonably according to the bottom area of the battery pack to reduce energy consumption.

[0044] like Figure 2 As shown, it also includes a telemetry mechanism 17, which includes an electric push rod 171 and an intelligent monitor 172. The telemetry mechanism 17 is located on the right side of the charging pile and its computer module 3. The telemetry mechanism 17 is used to intelligently detect the parking position and angle of the vehicle and intelligently control the operation of the attitude adjustment mechanism 11 so that the attitude adjustment cabin 5 can automatically adjust its attitude and adapt to the parking position and angle of the vehicle. The charging pile and its computer module 3 are fixedly connected to the right side with an electric push rod 171. The electric push rod 171 is electrically controlled and vertical. An intelligent monitor 172 is fixedly connected to the upper end of the moving part. The intelligent monitor 172 is equipped with an AI recognition algorithm. The intelligent monitor 172 is similar to an existing monitor with the function of identifying the vehicle position. It is used to detect the parking position of the vehicle in the parking space and the angle relative to the parking space boundary line. The image of the intelligent monitor 172 can be displayed in real time on the rotating display 4. The charging pile and its computer module 3 can accurately determine the parking position and angle of the vehicle based on the image display and algorithm recognition, and control the posture adjustment mechanism 11 to accurately face the midpoint and angle of the vehicle.

[0045] The installation and wiring method of the intelligent new energy vehicle battery management device includes: installing the recovery cabin 1 and fixing frame 2 of the intelligent new energy vehicle battery management device at the end of the charging parking space, and then installing and wiring the charging pile and its computer module 3 so that the charging pile and its computer module 3 can control the operation of the intelligent new energy vehicle battery management device and display and operate through the rotating display 4. The input cable of the charging pile and its computer module 3 for charging the vehicle power battery is separated from the power-consuming parts of the intelligent new energy vehicle battery management device, such as the recovery mechanism 10, the posture adjustment mechanism 11, the travel mechanism 12, the lifting mechanism 13, the retraction mechanism 14 and the temperature adjustment mechanism 15. That is, the external cable entering the intelligent new energy vehicle battery management device is a two-wire type, one wire is only used for input to the charging pile and its computer module 3, and the other wire is input to the power-consuming part of the intelligent new energy vehicle battery management device, which is used to ensure that the power of the charging pile and its computer module 3 when charging the vehicle power battery is not excessively occupied by the power-consuming part of the intelligent new energy vehicle battery management device.

[0046] The method for managing parameter information of a vehicle's power battery pack by the intelligent new energy vehicle battery management device is as follows: after the vehicle is parked in a charging parking space where the intelligent new energy vehicle battery management device is installed, first connect the charging pile and the charging head of its computer module 3 to the vehicle's charging end. At this time, the battery management system of the vehicle's battery pack will communicate data with the charging pile and its computer module 3, so that the charging pile and its computer module 3 can identify the vehicle's battery pack related data, such as battery health, total capacity and remaining capacity of the battery pack, battery temperature and other information, so that the charging pile and its computer module 3 can calculate the appropriate charging power, charging temperature or other charging-related solutions. After connecting the charging head of the charging pile and its computer module 3 to the vehicle's charging end, the owner can view the above information on the rotating display 4, manage and determine the vehicle's battery The final charging plan for charging the battery pack can be obtained by the owner, so that the owner can manage and view the relevant data of the vehicle battery pack in detail; during the charging process, the charging pile and its computer module 3 will also control the operation of the temperature control mechanism 15 in real time according to the exchanged battery pack related information, so that the temperature control mechanism 15 can input gases of different temperatures into the independent space formed by the front beam 7, the middle beam 8, the rear beam 9, the foldable insulation layer 91 and the lower side of the battery pack, so that the overall charging temperature of the battery pack is controlled within a suitable range. At the same time, the charging pile and its computer module 3 will also exchange information with the thermal management subsystem of the vehicle's battery management system in a monitoring and low-power operation state, so that the power of the charging pile and its computer module 3 to charge the battery pack can be more used in the charging process.

[0047] The working principle of the temperature management of the vehicle power battery pack during charging of the intelligent new energy vehicle battery management device is as follows: the owner can control the operation of the attitude adjustment mechanism 11 through the rotating display 4, so that the attitude adjustment mechanism 11 drives the attitude adjustment cabin 5 to rotate or translate, so that the attitude adjustment cabin 5 faces the parking angle and position of the vehicle; then the travel motor 123 is controlled to operate, and the recovery motor 104 is controlled to drive the recovery winding wheel group 101 and the recovery rope 102 to be in a released state, and the pull-back motor 142, the pull-back winding wheel group 143 and the recovery rope 102 are in a self-locking state. The operation of the travel motor 123 will drive the active wheel group 122 to rotate, so that the rear beam 9 moves to the left. At this time, the active wheel group 122 will drive the rear beam 9, the middle beam 8, the front beam 7 and the foldable insulation layer 91 to move synchronously to the left and enter the bottom of the vehicle when they are in a retracted state through the driven wheel group 121. When the front beam 7 is about to be located below the right edge of the bottom of the vehicle battery pack, the recovery motor 104, the recovery winding wheel group 101 and the recovery cable 102 can be controlled to be in a self-locking state. At this time, the front beam 7 will stop moving. At this time, the pull-back motor 142 can be controlled to drive the pull-back winding wheel group 143 and the pull-back cable 144 to be in a released state. At this time, the active wheel group 122 will drive the rear beam 9, the middle beam 8 and the foldable thermal insulation layer 91 to continue to move to the left, so that the rear beam 9, the middle beam 8, the front beam 7 and the foldable thermal insulation layer 91 are gradually expanded and expanded. Until the rear beam 9 is located below the left edge of the bottom of the vehicle battery pack, the travel motor 123 can be controlled to stop running and enter a self-locking state. At the same time, the pull-back motor 142 can be controlled to stop running and enter a self-locking state. At this time, the space formed by the rear beam 9, the middle beam 8, the front beam 7 and the foldable thermal insulation layer 91 can completely surround the lower side of the vehicle battery pack.Afterwards, the air pump 134 can be controlled to operate, and the air pump 134 will draw gas from the outside and input it into the folding airbag 131 through the interconnecting pipe 132 and the hose 133, so that the folding airbag 131 will be inflated. After the folding airbag 131 is inflated, it will expand downward to increase its height, thereby causing the folding airbag 131 to lift the rear beam 9, the middle beam 8, the front beam 7 and the folding thermal insulation layer 91 upward, so that the upper sides of the rear beam 9, the middle beam 8, the front beam 7 and the folding thermal insulation layer 91 will contact the vehicle battery pack, thereby causing the space between the rear beam 9, the middle beam 8, the front beam 7 and the folding thermal insulation layer 91 to cover the lower side of the battery pack, so that the lower side of the battery pack forms an isolated space from the outside. The method of building an independent space with the front beam 7, the middle beam 8, the rear beam 9, the folding thermal insulation layer 91 and the lower side of the battery pack can not only isolate the vehicle battery pack from the low-temperature or high-temperature air outside during charging, but also can adjust The temperature control mechanism 15 controls the temperature of the independent space, ensuring that the battery pack is within an environment suitable for charging. The foldable insulation layer 91 reduces the rate of temperature loss within the independent space, lowering the operating power of the temperature control mechanism 15 and reducing energy consumption. The foldable airbag 131 is inflated to lift the rear beam 9, center beam 8, front beam 7, and foldable insulation layer 91 to contact the underside of the battery pack. This achieves flexible lifting, preventing the rear beam 9, center beam 8, front beam 7, and foldable insulation layer 91 from mechanically and directly contacting the underside of the battery pack, thereby protecting the underside of the battery pack from mechanical damage. The charging station and its computer module 3 then control the operation of the temperature control mechanism 15 in real time based on the real-time temperature of the battery pack, allowing the temperature control mechanism 15 to regulate the temperature of the space between the rear beam 9, center beam 8, front beam 7, foldable insulation layer 91, and the underside of the battery pack.

[0048] After the battery pack is charged, the air pump 134 can be controlled to operate, so that the air pump 134 extracts the gas in the folding airbag 131, so that the folding airbag 131 shrinks upward and lowers its height, so that the rear beam 9, the middle beam 8, the front beam 7 and the folding insulation layer 91 move downward, so that the driving wheel group 122 and the driven wheel group 121 contact the ground again, so that the rear beam 9, the middle beam 8, the front beam 7 and the upper side of the folding insulation layer 91 are out of contact with the lower side of the vehicle battery pack, and then the pull-back motor 142 can be controlled to operate, so that the pull-back motor 142 drives the pull-back reel The winding wheel group 143 winds up the pull rope 144, so that the pull rope 144 drives the rear beam 9, the middle beam 8 and the foldable thermal insulation layer 91 to shrink and fold to reduce the area. At the same time, the recovery motor 104 is controlled to operate, so that the recovery motor 104 drives the recovery winding wheel group 101 to wind up the recovery rope 102, so that the recovery rope 102 drives the folded front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91 to move synchronously to the right side into the attitude adjustment cabin 5. When the front beam 7 moves to the right and resets, the spiral air pipe 152 will automatically The front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91 are folded and retracted by the pull-back mechanism 14, so that the posture adjustment cabin 5 can store the front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91. This can reduce the occupied area of the smart new energy vehicle battery management device, and the parking space can be withdrawn after storage to avoid damage caused by crushing when the vehicle enters or exits, and to prevent environmental debris from falling into the space between the front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91. In the parking space, frequent cleaning of the space between the front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91 is avoided, and by storing the front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91 into the attitude adjustment cabin 5, and cooperating with the attitude adjustment motor 115 and the electric slide rail 114 of the attitude adjustment mechanism 11, the attitude adjustment cabin 5 can adapt to the parking position of the vehicle in any attitude when the vehicle enters the parking space, so as to ensure that the front beam 7, the middle beam 8, the rear beam 9 and the foldable thermal insulation layer 91 are all within the accurate position range of the lower side of the vehicle battery pack.

[0049] The intelligent new energy vehicle battery management device manages the ambient temperature of the vehicle power battery pack during charging: the charging pile and its computer module 3 will control the operation of the temperature regulating mechanism 15 in real time according to the real-time temperature of the battery pack, so that the hot and cold ventilation unit 153 extracts gas from the space in the rear beam 9, the middle beam 8, the front beam 7, the foldable insulation layer 91 and the lower side of the battery pack through the rear spiral air pipe 152, the rear connecting pipe 154 and the rear ventilation row 155. The extracted gas is heated or cooled to the appropriate temperature required for battery charging by the controlled hot and cold ventilation unit 153, and then is discharged from the front spiral air pipe 152 to the lower side of the battery pack. The cyclone 152, the front connecting pipe 154 and the front ventilation exhaust 155 are output to the space between the rear beam 9, the middle beam 8, the front beam 7, the foldable insulation layer 91 and the lower side of the battery pack, thereby completing the ambient temperature control when the vehicle battery pack is charging, so that the battery pack is in a suitable charging temperature range. At the same time, the built-in thermal management system of the vehicle battery pack does not need to occupy too much charging power to work, ensuring that the battery pack can have full charging power, speeding up the battery charging speed, charging in a suitable temperature range, and also protecting the safety of the battery during charging and the battery life.

[0050] Example 3, as Figures 1-14 As shown, a management method of a smart new energy vehicle battery management device is as follows: S1. Drive the vehicle into the charging parking space where the intelligent new energy vehicle battery management device is installed, and connect the charging terminal of the vehicle through the charging pile and the charging head of the computer module 3; S2. The battery management system of the vehicle battery pack communicates data with the charging pile and its computer module 3 to identify the relevant data of the vehicle battery pack, so that the charging pile and its computer module 3 calculate the appropriate battery charging management plan of charging power and charging temperature, and display the above information on the rotating display 4, so that the owner can manage and determine the final charging plan for charging the vehicle battery pack; S3, controlling the front beam 7, middle beam 8, rear beam 9 and foldable insulation layer 91 of the intelligent new energy vehicle battery management device to contact and fit with the lower side of the vehicle battery pack, forming a temperature management space at the bottom of the vehicle battery pack that can be isolated from the outside world; S4, the charging pile and its computer module 3 will charge the vehicle battery pack in the form of an independent power supply cable, and manage the charging power required for charging through the data exchanged in S2. At the same time, the charging pile and its computer module 3 will control the operation of the temperature control mechanism 15 in real time according to the real-time temperature of the battery pack, so that the temperature control mechanism 15 can input gases of different temperatures into the independent space formed by the front beam 7, the middle beam 8, the rear beam 9, the foldable insulation layer 91 and the lower side of the battery pack, and enable the thermal management subsystem of the vehicle's own battery management system to be in a monitoring and low-power operation state, so that the power of the charging pile and its computer module 3 for charging the battery pack can be used more for the charging process; S5. After the charging pile and its computer module 3 identify that the vehicle battery pack is charged to a safe capacity through data exchange, the charging pile and its computer module 3 will stop supplying power to the vehicle and disconnect the information exchange status with the vehicle. At the same time, the charging pile and its computer module 3 will control the temperature control mechanism 15 to stop running, and control the front beam 7, middle beam 8, rear beam 9 and foldable insulation layer 91 to be reset and recovered into the attitude adjustment cabin 5. In this way, the management of the battery charging temperature of the vehicle during the charging process is completed.
