Description

Technical Field

[0001] The present application relates to the field of charging piles, and in particular to an emergency mobile charging pile, a charging method and a storage medium thereof. Background Art

[0002] Nowadays, new energy vehicles are usually charged through charging piles. A small number of new energy vehicles (such as NIO) are charged by directly replacing the battery. This creates a problem. When the owner miscalculates the remaining mileage of the car, or the car's system miscalculates its own remaining mileage, the car may run out of power before reaching the charging station or parking in its own parking space. If this happens to a fuel car, the owner can just open the fuel tank and pour the oil in.

[0003] However, when new energy vehicles and other equipment that need to be charged encounter an emergency and cannot be moved to the charging equipment, for example, when the new energy vehicle is close to the charging equipment but the vehicle is completely out of power, the owner needs to call a tow truck or call a friend to drive the new energy vehicle to the charging location, which is very troublesome. Summary of the invention

[0004] In order to improve the problem that is difficult to solve when a new energy vehicle runs out of power, the present application provides an emergency mobile charging pile, a charging method and a storage medium thereof.

[0005] The present application provides an emergency mobile charging station, which adopts the following technical solution: An emergency mobile charging pile comprises a cart, a plurality of driving wheels are arranged at the lower end of the cart, a battery pack group for energy storage is arranged on the cart, a portable charging pile is also arranged on the cart, the battery pack group is electrically connected to the portable charging pile for power supply, and a charging gun for charging new energy vehicles is arranged on the portable charging pile.

[0006] By adopting the above technical solution, when the new energy vehicle runs out of power, the user can move the battery pack to the side of the new energy vehicle by pushing a cart, and then charge it through a portable charging pile. For example, if the battery runs out of power only two kilometers away from your community, you can go to the property to get it, charge it temporarily, and then drive to your own parking space in the community to charge it through a normal charging pile. This is convenient and fast, saves towing fees, facilitates operation, and saves social resources.

[0007] Optionally, the cart is also provided with a portable generator, which is electrically connected to the battery pack to provide power.

[0008] By adopting the above technical solution, when the battery pack is left for a long time without being charged, resulting in insufficient power, the battery pack can be charged by a portable generator, and then the battery pack can be used to act as a voltage stabilizer to compensate for the defect of unstable power generation of the portable generator and charge the new energy vehicle.

[0009] Optionally, the cart is also provided with a driving motor, a level, a data processing module, a pressure detection module, a temperature detection sensor, and an electric energy collection module. The temperature detection sensor is used to detect the internal temperature of the battery pack to obtain energy storage temperature data. The electric energy collection module is used to collect the electric energy data of the battery pack and the electric energy data of the portable generator to obtain electric energy collection data. The level is used to detect the horizontal state of the cart to obtain a horizontal detection signal. The pressure detection module is used to detect the mass pressure of the cart to obtain a pressure detection signal. The data processing module is used to receive the energy storage temperature data and the electric energy collection data, and output the maximum allowable charging signal to the portable charging pile after data processing. The data processing module is used to receive the horizontal detection signal and the pressure detection signal, and output the drive auxiliary signal to the drive motor after data processing. The drive motor is used to drive the drive wheel to assist the movement of the cart.

[0010] By adopting the above technical solution, when pushing the cart uphill, since the portable charging pile and battery pack on the cart are of large mass, the driving auxiliary signal is used to control the driving motor to give appropriate power to assist the user in pushing the cart uphill, without pulling the user to run due to excessive speed, but only playing an auxiliary role, ensuring that users with less strength, such as women, can move the cart to the designated position with less power consumption, which is convenient and quick, and improves efficiency.

[0011] The present application provides a charging method for an emergency mobile charging pile, which adopts the following technical solution: A charging method for an emergency mobile charging pile, comprising: Get the start signal and charging protocol data; Determine the allowed charging data through the charging protocol data, the preset charging type threshold, and the preset allowed charging interval; obtain the electric energy collection data, the electric energy collection data including the energy storage voltage; The maximum allowed charging signal is determined and outputted according to the allowed charging data, the energy storage voltage, and a preset energy storage damage threshold.

[0012] By adopting the above technical solution, it is automatically determined whether it is suitable, and the maximum charging power output is used for charging within the allowable range, thereby improving efficiency and safety.

[0013] Optional, including: Determine and output an alarm signal based on the energy storage voltage and the energy storage damage threshold; The electric energy collection data includes power generation data, and the energy storage temperature data is obtained; The maximum allowable charging signal is determined by the power generation data, the allowable charging data, the energy storage temperature data, and a preset temperature loss threshold.

[0014] By adopting the above technical solution, when the remaining capacity of the battery pack is insufficient, it is automatically determined whether charging while generating electricity is allowed, and the maximum charging power allowed during power generation is automatically calculated, which is convenient and quick.

[0015] Optional, including: Acquire the horizontal detection data, acquire the pressure detection signal, acquire the wheel rotation direction data, and acquire the timing data; Determine the forward direction data by using the wheel rotation direction data, the timing data, and a preset forward timing threshold; Determine the tilt angle data through the horizontal detection data and a preset horizontal threshold; Determine the sliding tendency data through the tilt angle data and the pressure detection signal; Determine and output a drive assist signal based on the sliding tendency data, a preset drive assist threshold, and the forward direction data; determine forward current direction data based on the forward direction data and the wheel rotation direction data; The electric energy collection data includes driving current data, and the reverse current data is determined by the forward current direction data and the driving current data; A new driving auxiliary signal is determined and outputted according to the reverse current data and the original driving auxiliary signal.

[0016] By adopting the above technical solution, the output power of the drive motor is automatically adjusted and adapted, so that the speed of the automatically adapted drive wheel is closer to the speed the user wants to achieve, thereby improving the accuracy of the assistance and further reducing the user's effort.

[0017] Optional, including: The pressure detection signal includes a plurality of wheel pressure detection data to obtain rotation speed data; Determine forward pressure data by using the wheel pressure detection data and the forward direction data; Determine a speed difference value by using the forward pressure data and the speed data; Determining slope change data by using the speed difference, a preset speed difference threshold, and a preset wheelbase threshold; Determine new slope angle data by using the slope change data and the inclination angle data; Determine auxiliary change time data by using the rotation speed data and the wheelbase threshold value; Replacing the tilt angle data with the new slope angle data to determine a new driving auxiliary signal; The auxiliary change time data is used to determine whether the new driving auxiliary signal replaces the original driving auxiliary signal and outputs it.

[0018] By adopting the above technical solution, the front driving wheel contacts the new slope in advance, and the new driving auxiliary signal and the auxiliary change time data are automatically judged, so that the driving auxiliary signal can be adapted immediately after the cart as a whole enters the new slope. This reduces the probability of the cart rushing out due to the same output power of the driving motor when going from a high slope to a low slope, and also reduces the probability of the user being injured due to a sudden increase in pressure on the user due to the same output power of the driving motor when going from a low slope to a high slope, thereby improving safety and stability.

[0019] The present application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium stores a computer program that can be loaded and executed by a processor and that implements a charging method for an emergency mobile charging pile.

[0020] By adopting the above technical solution, the computer program is stored in a computer-readable storage medium.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. It is convenient and fast, saves towing fees, is easy to operate, and saves social resources.

[0022] 2. After the cart enters a new slope automatically, the drive auxiliary signal is adapted immediately to reduce the probability of the cart rushing out due to the same output power of the drive motor when going from a high slope to a low slope, and also reduce the probability of the user being injured due to a sudden increase in pressure received by the user due to the same output power of the drive motor when going from a low slope to a high slope, thereby improving safety and stability.

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The present application embodiment discloses an emergency mobile charging station. Figure 1 and Figure 2The emergency mobile charging pile includes a cart 1, which includes a handle for users to push and control. The lower end of the cart 1 is rotatable with at least three driving wheels 11. For ease of description, four driving wheels 11 are used in this embodiment. The bottom of the cart 1 is square, and the four driving wheels 11 are respectively located at the four corners of the lower end surface of the cart 1. A battery pack 12 for energy storage is fixedly connected to the cart 1. The battery pack 12 can be a lead-acid battery or a lithium-ion battery or other storage battery. Without considering the price, the lithium-ion battery has the advantages of light weight and high energy density, and the lithium-ion battery is preferably used. A portable charging pile 13 and a portable generator 2 are also installed on the cart 1. The battery pack 12 is electrically connected to the portable charging pile 13 for power supply. The portable charging pile 13 is equipped with a charging gun 14 for charging new energy vehicles. The portable generator 2 is electrically connected to the battery pack 12 to realize the portable generator 2 to power the battery pack 12. The portable charging pile 13 may include one of a rectifier or an inverter. The portable charging pile 13 including a rectifier is used to output direct current for charging, and the portable charging pile 13 including an inverter is used to output alternating current for charging. Under the premise of considering the coordination with the battery pack 12, the rectifier only needs to rectify, filter and stabilize the direct current directly output by the battery pack 12 to output it for charging, while the inverter needs to invert the direct current directly output by the battery pack 12 into alternating current, and then needs to cooperate with a transformer and a filter to ensure the quality and stability of the waveform. Therefore, the volume including the rectifier will be smaller. It is better to include a rectifier, and include two models of a rectifier or an inverter. It can also include a rectifier and an inverter at the same time, which will result in a large volume and heavy mass, but the adaptability will be greatly improved, or a power reduction strategy can be adopted to reduce the output power of the rectifier and the inverter, thereby reducing the volume and mass. The portable generator 2 can be a diesel generator or a gasoline generator. Without considering the price, the gasoline generator has a smaller volume and lighter weight under the condition of the same power generation capacity, so the gasoline generator is preferably used.

[0033] Reference Figure 1 and Figure 2 and Figure 3The cart 1 is also equipped with a driving motor 21, a level 22, a data processing module 23, a pressure detection module 24, a temperature detection sensor 25, and an electric energy collection module 26. The temperature detection sensor 25 is used to detect the temperature of the battery pack 12 to obtain energy storage temperature data. The electric energy collection module 26 is used to collect the output voltage, current and power of the battery pack 12 and the output voltage, current and power of the portable generator 2 to obtain electric energy collection data. The electric energy collection module 26 can use instruments such as electric energy meters. One driving motor 21 can be used, and then the four driving wheels 11 can be controlled to rotate simultaneously through a linkage mechanism. Four driving motors 21 can also be used to control the four driving wheels 11 respectively. The level meter 22 is used to detect the horizontal state of the cart 1 to obtain a horizontal detection signal. The pressure detection module 24 is used to detect the mass pressure of the cart 1 to obtain a pressure detection signal. The pressure detection module 24 can adopt a pressure sensor, and the number of the pressure detection modules 24 corresponds to the number of the driving wheels 11. The pressure detection module 24 is used to detect the pressure exerted on the driving wheels 11. In this embodiment, the number of the pressure detection modules 24 is four, and the four pressure detection modules 24 are respectively installed on the four corners of the lower end surface of the cart 1, so that the four pressure detection modules 24 correspond to the four driving wheels 11 one by one.

[0034] The data processing module 23 can adopt the cooperation of a processor and a database, or directly adopt a terminal device, such as a computer. The database is used to store various threshold data, such as the allowed charging interval, energy storage damage threshold, temperature loss threshold, forward timing threshold, drive assist threshold, coil conversion threshold, slope change threshold, etc. The processor is used to receive horizontal detection signals, pressure detection signals, energy storage temperature data, and electric energy acquisition data, and call the corresponding threshold data from the database for data processing and calculation, and obtain a drive assist signal to output to the drive motor 21, and output the maximum allowable charging signal to the rectifier or inverter in the portable charging pile 13 to control the output voltage and current.

[0035] The processor may include a central processing unit such as a CPU or MPU or a host system built around a CPU or MPU, including hardware or software. After the meter has a processor, people can freely control the metering instrument through programming to make it run according to people's wishes. The processor can control local measurement transmission, remote measurement transmission, remote communication, etc. through internal protocols. Internal protocols refer to all protocols that achieve mutual communication or links within the same metering instrument or the same system, including: human-computer interaction protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, internal bus (I-Bus) protocols, etc. Part or all of the protocols. With the development of integrated circuit technology, some protocols that belong to the external bus (E-Bus) protocol are also classified as internal protocols after the external bus (E-Bus) is integrated into the chip.

[0036] The implementation principle of an emergency mobile charging pile in the embodiment of the present application is: The present application embodiment discloses a charging method for an emergency mobile charging pile. Figure 4 , the charging method of the emergency mobile charging pile includes the following steps: S1. Obtain a start signal and obtain charging protocol data; S11, determining the allowed charging data through the charging protocol data, the preset charging type threshold, and the preset allowed charging interval; S12, obtaining electric energy collection data, where the electric energy collection data includes energy storage voltage; S13, determining and outputting a maximum allowable charging signal based on the allowable charging data, the energy storage voltage, and a preset energy storage damage threshold.

[0037] In detail: when it is necessary to charge the new energy vehicle, the user first needs to start the portable charging pile 13. At this time, the user inputs a start signal, which can be input through a button or other means, and then inserts the charging gun 14 into the charging interface of the new energy vehicle to obtain the charging protocol data of the charging interface. The charging protocol data includes the charging type (AC or DC), rated charging power, battery type and other data allowed by the charging interface of this new energy vehicle. The preset charging type threshold is the portable charging pile 13 itself when it leaves the factory, that is, if it carries an inverter, the charging type threshold is AC charging, and if it carries a rectifier, the charging type threshold is DC charging. If a rectifier and an inverter are carried at the same time, one charging gun 14 is usually connected to the inverter and the other charging gun 14 is connected to the rectifier. At this time, the charging type threshold is stored in the charging gun 14 instead of the portable charging pile 13. The charging type in the obtained charging protocol data is compared with the charging type threshold. If they are consistent, charging can be performed; the preset allowed charging interval is the charging interval that the portable charging pile 13 can adjust and adapt. The power size is then calculated through the rated charging power and the allowed charging range in the charging protocol data to obtain the allowed charging data. The allowed charging data is the intersection of the rated charging power and the allowed charging range. For example, if the allowed charging range is [200,1000]W, if the rated charging power is [800,4000]W, then the allowed charging data is calculated to be [800,1000]W; the power collection data includes the energy storage voltage, that is, the output voltage of the battery pack 12 is detected to determine the battery pack 1 2 The current remaining capacity, the energy storage damage threshold means that if the discharge continues below this voltage, the service life of the battery pack 12 will be permanently damaged. For example, if the energy storage damage threshold is 3.2V, if the energy storage voltage is 4V, 4>3.2, then it is allowed to continue to output. At this time, the maximum allowable charging signal is a voltage of 4V, and the current can be pulled high to make the power between [800,1000]W, which should theoretically reach 1000W. If the energy storage voltage is 3.2V, then it is not allowed to continue to discharge. At this time, the maximum allowable charging signal is 0.

[0038] Reference Figure 5 , further comprising the following steps: S2, determining an alarm signal through energy storage voltage and energy storage damage threshold and outputting it; S21, electric energy collection data including power generation data, and energy storage temperature data; S22, determining the maximum allowable charging signal through the power generation data, the allowable charging data, the energy storage temperature data, and the preset temperature loss threshold.

[0039] In detail: when the energy storage voltage is lower than the energy storage damage threshold, an alarm signal is output to remind the user that the discharge cannot continue. At this time, the portable generator 2 can be turned on to generate electricity. The power data is the output power of the portable generator 2 to the battery pack 12. The energy storage temperature data is the internal temperature of the battery pack 12. If the power data is 1200W, the allowed charging data is [800,1000]W. Even if the energy storage voltage is equal to the energy storage damage threshold, it is allowed to continue to discharge and charge at the maximum power of 1000W allowed by the charging data. Then, the internal consumption of the battery pack 12 is measured through the energy storage temperature data and the temperature loss threshold. If the energy storage temperature data is 50℃, the temperature loss threshold is set to P=x*C, where C is the energy storage temperature data. According to data, if x is 1, the calculated heat loss is 50W, which means that after an input of 1200W, only 1150W can be actually output, of which 50W is converted into heat energy and dissipated, but 1150W is still greater than 1000W, so the maximum allowable charging signal is 1000W at this time. If the power generation data is 900W, the allowable charging data is [800,1000]W, and the heat loss is 50W. The maximum allowable charging signal is 850W at this time. If the power generation data is 800W, after removing the heat loss, the actual charging power is less than 800W. At this time, the maximum allowable charging signal is 0. Then, when the energy storage voltage rises beyond the energy storage damage threshold, normal charging can be performed.

[0040] Reference Figure 6 , further comprising the following steps: S3, obtaining horizontal detection data, obtaining pressure detection signals, obtaining wheel rotation direction data, and obtaining timing data; S31, determining forward direction data through wheel rotation direction data, timing data, and a preset forward timing threshold; S32, determining the tilt angle data through the horizontal detection data and the preset horizontal threshold; S33, determining the sliding tendency data through the tilt angle data and the pressure detection signal; S34, determining and outputting a driving assistance signal according to the sliding tendency data, a preset driving assistance threshold value, and the forward direction data; S35, determining the forward current direction data through the forward direction data and the wheel rotation direction data; S36, the electric energy collection data includes driving current data, and the reverse current data is determined by the forward current direction data and the driving current data; S37, determining a new driving auxiliary signal through the driving adjustment data and the original driving auxiliary signal and outputting it.

[0041] In detail: the wheel rotation direction data is the direction in which the driving wheel 11 rotates, and the timing data is the timing when the driving wheel 11 rotates in the same direction. If the rotation direction is reversed, the timing will be restarted. If the timing data is 10s, the forward timing threshold is set to 5s, 10>5, then it means that the rotation direction of the driving wheel 11 at this time is the forward direction data; if the horizontal detection data is 10°, the horizontal threshold is set to 0°, then the inclination angle data can be calculated to be 10°, if the pressure detection signal is 1000N, the sliding tendency data is the force sliding along the inclination angle, so the sliding tendency data can be calculated to be 1000N*sin 10°, the driving assistance threshold is how much current can generate how much magnetic field, and finally how much force is generated to rotate the driving wheel 11. For example, the driving assistance threshold is F=z*I, z is a coefficient related to factors such as the number of bundled coils in the driving motor 21 and the number of turns of a bundle of coils. That is, after a current of I is passed, a force of F to rotate the driving wheel 11 will be generated. At this time, F=1000N is required to assist the user to go uphill, so that I can be calculated. Here, I is the driving assistance signal; the forward direction data can be used to determine in which direction the driving wheel 11 should rotate, that is, in which direction the current should flow in the driving motor 21. This is the forward current direction data. If the speed of the driving wheel 11 is greater than the speed provided by the driving motor 21, for example, the driving motor 21 only provides a speed of 5r / s, but the driving wheel 11 When the user's thrust reaches a speed of 6r / s, the drive wheel 11 will actively drive the rotating shaft of the drive motor 21 to generate a speed of 6r / s in the coil. Since the coil only provides a current with a speed of 5r / s, there will be an extra speed of 1r / s. At this time, the extra speed of the rotating shaft will cut the magnetic flux lines of the coil, generating a current direction opposite to the forward current direction data in the coil, and the drive current data is the current size collected. The reverse current data can be obtained by combining the current size and the current direction, and then the drive auxiliary signal can be adjusted according to the reverse current data. For example, if the reverse current data is -1A and the drive auxiliary signal is 5A, the new drive auxiliary signal can be 6A, so that the power provided by the drive motor 21 to the drive wheel 11 reaches 6r / s, reducing the user's force.

[0042] Reference Figure 7 , may also include the following steps: S4, the pressure detection signal includes a plurality of wheel pressure detection data; S41, determining forward pressure data according to wheel pressure detection data and forward direction data; S42, determining a speed difference value through forward pressure data and speed data; S43, determining slope change data according to the speed difference, a preset speed difference threshold, and a preset wheelbase threshold; S44, determining new slope angle data through the slope change data and the inclination angle data; S45, determining auxiliary change time data according to the speed data and the wheelbase threshold; S46, replacing the inclination angle data with the new slope angle data to determine a new driving auxiliary signal; S47, determining through the auxiliary change time data to replace the original driving auxiliary signal with a new driving auxiliary signal and outputting it.

[0043] In detail: the pressure detection signal is the sum of the pressures detected by the four pressure detection modules 24, and the wheel pressure detection data is the pressure detected by a single pressure detection module 24. The forward direction data can be used to determine which two driving wheels 11 represented by the wheel pressure detection data are the two driving wheels 11 at the front end. Once the slope changes, for example, just entering a steeper slope, or ending the uphill journey and entering a horizontal section, the two driving wheels at the front end will first contact the new road surface with a different slope, and the horizontal detection data will also change. Principle explanation: for example, the original slope is 30°, the new slope is 0°, and the driving wheel 11 advances 10cm when it rotates one circle. At this time, the front driving wheel 11 falls on the new slope, and the rear driving wheel 11 rotates one circle and advances 10cm on the original slope. However, if it is equivalent to an angle of 0°, advancing 10cm at an angle of 30° is equivalent to advancing 10cm*sin at an angle of 0°. 30°=5√3cm, so the driving wheel 11 corresponding to the forward pressure data should theoretically only rotate 5√3 / 10=0.87 circles at this time, but due to the change in the inclination angle of the cart 1 itself, that is, the front driving wheel 11 has moved forward a distance on the ground at 0°, but the rear driving wheel 11 is still on the ground at 30°, but at this time the inclination angle of the cart 1 itself may become 25°, not 30°. When the rear driving wheel 11 also enters the ground at 0°, the angle of the cart 1 itself will completely become 0°. Therefore, at this time, there is a difference between the front driving wheel 11 and the rear driving wheel 11. The wheelbase threshold is the distance data between the front driving wheel 11 and the rear driving wheel 11. This is the principle that the speed difference, the speed difference threshold and the wheelbase threshold can obtain the slope change data; the slope change data is the slope difference between the driving wheel 11 corresponding to the forward pressure data and the rear driving wheel 11. The new slope angle can be obtained by calculation. Data = inclination angle data - slope change data, and the speed of the cart 1 leaving the original slope can be calculated through the rotation speed data of the rear end driving wheel 11. For example, if the wheelbase threshold is 150cm, the rotation speed data is 2r / s, and one circle is 10cm, the timing starts from the moment the front end driving wheel 11 leaves the original slope and enters the new slope. It also takes 150 / (2*10)=7.5s to completely leave the original slope, which is the auxiliary change time data, indicating that after 7.5s, the rotation speed of the rotating shaft of the driving motor 21 needs to be readjusted to adapt to the new slope to prevent the cart 1 from running out; the inclination angle data is replaced by the new slope angle data, and the calculation of steps S33 to S37 is performed to obtain a new drive auxiliary signal, which will replace the original drive auxiliary signal after the time indicated by the auxiliary change time data, that is, the original drive auxiliary signal is stopped from being output after 7.5s, and the new drive auxiliary signal is output instead.

[0044] The present application embodiment discloses a computer-readable storage medium. Figure 1 The computer-readable storage medium stores a computer program that can be loaded and executed by a processor for executing a charging method for an emergency mobile charging pile.

[0045] Computer-readable storage media include, for example, various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
