Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of an application scenario provided by an embodiment of the present invention, as shown in fig. 1, including a charging cabinet 11 and an electric vehicle 12, where the charging cabinet 11 is used for charging the electric vehicle 12. The electric vehicle 12 may be an electric vehicle of the user himself or a shared electric vehicle, and provides convenience for traveling of the user.
The electric vehicle 12 is relatively environmentally friendly because it operates on electric energy, but charging of the electric vehicle 12 is a significant problem. The charging cabinet 11 can be arranged at a certain interval on the roadside, and when the electric quantity of the electric vehicle 12 is insufficient, the electric vehicle 12 can be charged by the charging cabinet 11.
The charging cabinet 11 is provided with a battery, and when the electric vehicle 12 is connected with the charging cabinet 11, the battery in the charging cabinet 11 charges the electric vehicle 12. Since the battery in the charging cabinet 11 needs to operate within a certain temperature range, and beyond the certain temperature range, the battery in the charging cabinet 11 may stop operating or the charging efficiency is low. When the battery in the charging cabinet 11 stops operating, the electric vehicle 12 cannot be charged. When the efficiency of charging the battery in the charging cabinet 11 is low, it may take a long time to fully charge the electric vehicle 12, so as to ensure that the user can travel a long distance using the electric vehicle 12. The long charging time may cause the user to be unable to wait, and further, the battery may be damaged when the battery is operated in a higher or lower temperature range for a long time.
Since the electric vehicle 12 is generally installed outdoors and a user travels using the electric vehicle 12, the charging cabinet 11 for charging the electric vehicle 12 is generally installed outdoors for convenience of use, and the outdoor temperature and environment are difficult to control, and thus a solution to this problem is required.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic structural diagram of a charging cabinet according to an embodiment of the present invention, as shown in fig. 2, including a first battery 21, a controller 22, a first temperature sensor 23, and an air deflector 24, where the first temperature sensor 23 is connected to the first battery 21 and the controller 22, respectively, where:
the first temperature sensor 23 is configured to acquire a first temperature of the first battery 21 and send the first temperature to the controller 22.
The charging cabinet in the embodiment of the present invention can realize automatic temperature control of the first battery, wherein the first battery 21 is a battery for charging an electric vehicle, and when the temperature of the first battery 21 exceeds a certain range, the temperature of the first battery 21 needs to be controlled. In order to obtain the temperature of the first battery 21, a first temperature sensor 23 is provided, wherein the first temperature sensor 23 may be provided inside the first battery 21 or may be directly connected to the first battery 21. The first temperature sensor 23 is activated to obtain the first temperature of the first battery 21 in real time, and then send the first temperature of the first battery 21 to the controller 22.
The controller 22 is configured to control the air deflector 24 to rotate when the first temperature is greater than or equal to a first preset value, and control the first battery 21 to perform a discharging operation when the first temperature is less than or equal to a second preset value.
The controller 22 is disposed inside the charging cabinet, and determines whether the first temperature is within a certain range after acquiring the first temperature sent by the first temperature sensor 23. In the embodiment of the present invention, the first preset value is an upper limit value of the operating temperature of the first battery 21, and when the temperature of the first battery 21 is greater than or equal to the first preset value, the temperature of the first battery 21 is at an excessively high value; the second preset value is a lower limit value of the operating temperature of the first battery 21, and when the temperature of the first battery 21 is less than or equal to the second preset value, the temperature of the first battery 21 is at an excessively low value. Wherein the first preset value is larger than the second preset value.
The temperature of the first battery 21 is at a value that is too high or too low, which is detrimental to the operation of the first battery 21. For example, when the temperature of the first battery 21 is at an excessively high value, the internal temperature of the first battery 21 is excessively high, and a risk of fire or the like may occur, when the temperature of the first battery 21 is at an excessively low value, the first battery 21 stops operating, and the like.
Therefore, after acquiring the first temperature of the first battery 21, the controller 22 determines the first temperature, determines whether the first temperature is greater than or equal to a first preset value, whether the first temperature is less than or equal to a second preset value, and so on.
When the first temperature is greater than or equal to the first preset value, it indicates that the first battery 21 operates at a higher temperature, and at this time, the temperature of the first battery 21 needs to be reduced. Therefore, the controller 22 controls the air deflector 24 to rotate when the first temperature is greater than or equal to the first preset value. When 24 rotations of aviation baffle, can accelerate the inside circulation of air of the cabinet that charges, the higher air discharge of the cabinet inside temperature that will charge, the lower air of the cabinet outside temperature that will charge inhales, reduces the inside temperature of the cabinet that charges, and then reduces the temperature that is located the inside first battery 21 of the cabinet that charges.
When the first temperature is less than or equal to the second preset value, it indicates that the first battery 21 operates at a lower temperature, and at this time, the temperature of the first battery 21 needs to be raised. Therefore, the controller 22 controls the first battery 21 to perform the discharging operation when the first temperature is less than or equal to the second preset value. The first battery 21 performs a discharging operation, that is, the first battery 21 is used as a power supply to supply power to other electrical appliances, the other electrical appliances are equivalent to resistors, and the first battery 21 also has an internal resistance. Therefore, when the first battery 21 performs the discharging operation, heat can be generated inside the first battery 21, thereby increasing the temperature of the first battery 21.
Through the manner, adjustment can be performed when the temperature of the first battery 21 is too high or too low, so that the temperature of the first battery 21 is controlled within a range which is greater than the second preset value and smaller than the first preset value. When the temperature of the first battery 21 is within the range, it indicates that the first battery 21 is within the normal operating temperature range, and the electric vehicle can be normally charged.
The charging cabinet provided by the embodiment of the invention comprises a first battery, a controller, a first temperature sensor and an air deflector, wherein the first temperature sensor is respectively connected with the first battery and the controller, the first battery is used for charging an electric vehicle, and the first temperature sensor is used for acquiring a first temperature of the first battery and sending the first temperature to the controller. After the first temperature is obtained, the controller can judge whether the first battery works within a certain temperature range according to the first temperature. When the first temperature is greater than or equal to the first preset value, the controller can control the air deflector to rotate, discharge the air with higher temperature inside the charging cabinet, absorb the air with lower temperature outside the charging cabinet, reduce the temperature inside the charging cabinet, and then reduce the temperature of the first battery inside the charging cabinet through the transmission of the temperature. When the first temperature is less than or equal to the second preset value, the controller can control the first battery to perform a discharging operation, so that the first battery generates heat energy from electric energy inside the first battery when performing a discharging operation, and the temperature of the first battery is increased. According to the charging cabinet provided by the embodiment of the invention, the first temperature of the first battery is obtained in real time through the first temperature sensor, and the temperature of the first battery is regulated and controlled through the controller when the first temperature is too high or too low according to whether the first temperature exceeds a certain range, so that the temperature of the first battery is not too high or too low, and the charging cabinet is beneficial to charging an electric vehicle.
The following detailed description of the embodiments of the present invention will be made with reference to FIG. 3 by way of specific examples
Fig. 3 is a schematic structural diagram of a charging cabinet according to another embodiment of the present invention, as shown in fig. 3, including a first battery 31, a controller 32, a first temperature sensor 33, and an air deflector 34, where the first temperature sensor 33 is connected to the first battery 31 and the controller 32, respectively, where:
the first temperature sensor 33 is configured to obtain a first temperature of the first battery 31 and send the first temperature to the controller 32; the controller 32 is configured to control the air deflector 34 to rotate when the first temperature is greater than or equal to a first preset value, and control the first battery 31 to perform a discharging operation when the first temperature is less than or equal to a second preset value.
Optionally, the charging cabinet further includes a heater 35, the heater 35 is connected to the controller 32, wherein:
the controller 32 is configured to send a heating instruction to the heater 35 when the first temperature is less than or equal to a second preset value;
the heater 35 is configured to receive the heating instruction sent by the controller 32, and start a heating operation according to the heating instruction.
The heater 35 is used for providing heat, and when the first temperature is less than or equal to a second preset value, the temperature of the first battery 31 needs to be raised. One possible implementation is to provide one or more heaters 35 in the charging cabinet in addition to the first battery 31 for discharging and warming. The heater 35 is connected to the controller 32, when the first temperature is less than or equal to the second preset value, the controller 32 sends a heating instruction to the heater 35, and after receiving the heating instruction sent by the controller 32, the heater 35 starts heating operation according to the heating instruction.
The heater 35 is capable of raising the temperature inside the charging cabinet after performing a heating operation, thereby raising the temperature of the first battery 31 through temperature transmission. By the heating operation of the heater 35 and the discharging operation of the first battery 31, the temperature of the first battery 31 can be raised more quickly, shortening the time for raising the temperature of the first battery 31.
Optionally, the charging cabinet further comprises a fan 36, the fan 36 is connected to the controller 32, wherein:
the controller 32 is configured to send a rotation instruction to the fan 32 when the first temperature is greater than or equal to the first preset value.
The fan 36 is configured to receive the rotation instruction sent by the controller 32 and rotate according to the rotation instruction.
The fan 36 can be rotated to accelerate the air circulation. The fan 36 is connected to the controller 32 and is controlled by the controller 32 to operate. When the first temperature is greater than or equal to the first preset value, the first battery 31 needs to be cooled. One possible implementation is to provide one or more fans 36 in the charging cabinet, in addition to using the air deflectors 34 to reduce the temperature of the charging cabinet and thus the first battery 31. One or more fans 36 may be operatively associated with the air deflection plates 34.
The fan 36 is connected to the controller 32, when the first temperature is greater than or equal to the first preset value, the controller 32 sends a rotation instruction to the fan 36, and after receiving the rotation instruction sent by the controller 32, the fan 36 starts a rotation operation according to the rotation instruction. After fan 36 starts the rotation operation, can accelerate more the circulation of air to with the cooperation of aviation baffle 34, faster will charge the higher air of cabinet internal temperature and heat and discharge, inhale the lower air of cabinet external temperature that charges, reduce the inside temperature of cabinet that charges, thereby reduce the temperature of first battery 31 according to the temperature transmission. By rotating the fan 36 and the air guide plate 34, the temperature of the first battery 31 can be reduced more quickly, and the time for cooling the first battery 31 can be shortened.
The scheme of the embodiment of the present invention will be described in detail with reference to fig. 4 and 5.
Fig. 4 is a schematic diagram of the temperature increase of the charging cabinet according to the embodiment of the present invention, and as shown in fig. 4, when the temperature of the first battery is too low, the temperature increase is mainly realized through the first temperature sensor, the controller, the first battery, and the heater.
The first temperature sensor acquires a first temperature of the first battery and sends the first temperature to the controller. The controller obtains a first temperature of the first battery and judges whether the first temperature exceeds a certain range.
When the first temperature of the first battery is less than or equal to the second preset value, a possible implementation manner is that the controller sends a discharge instruction to the first battery, and the first battery receives the discharge instruction and performs a discharge operation according to the discharge instruction sent by the controller. Since the first battery has an internal resistance, electric energy can be converted into heat energy when the first battery performs a discharging operation, thereby increasing the temperature of the first battery.
Another possible implementation manner is that the controller sends a heating instruction to the heater, and the heater receives the heating instruction and performs the heating operation according to the heating instruction sent by the controller. When the heater performs a heating operation, the temperature inside the charging cabinet may increase, thereby increasing the temperature of the first battery according to the temperature transfer.
Optionally, when the first temperature of the first battery is less than or equal to the second preset value, the controller sends a discharge instruction to the first battery and also sends a heating instruction to the heater, the first battery discharges through the discharge instruction, and the heater heats through the heating instruction, so that the temperature of the first battery is increased more quickly.
Optionally, the heater is an electric heater, and a power supply is required to supply power to the heater when the heater performs heating operation. One possible implementation is to provide a power supply within the charging cabinet to supply power to the heater. Another possible implementation is that the heater is powered by the first battery while the first battery performs the discharging operation. Because the first battery performs the discharging operation and the heater performs the heating operation when the first temperature of the first battery is less than or equal to the second preset value, the discharging of the first battery is used for supplying power to the heater, and the electric quantity can be saved. Furthermore, the power supply of the heater can also be provided by the power supply arranged in the charging cabinet and the discharge of the first battery together, so that the waste of the discharge of the first battery is avoided, and the problem of low working efficiency of the heater caused by the fact that the first battery is not enough to provide the electric quantity required by the heater for heating is also avoided.
Optionally, the charging cabinet further includes a second temperature sensor, the second temperature sensor is connected to the controller, the second temperature sensor is configured to acquire a second temperature inside the charging cabinet and send the second temperature to the controller, and the controller is configured to send a heating instruction to the heater according to the second temperature, or send a rotation instruction to the fan.
In the embodiment of the invention, the temperature of the first battery is mainly required to be regulated, so that the first temperature sensor is arranged to acquire the first temperature of the first battery in real time. When the first temperature of the first battery is regulated, the temperature inside the charging cabinet needs to be regulated to regulate the first temperature of the first battery. Therefore, a possible implementation manner is that a second temperature sensor is further arranged inside the charging cabinet, and the second temperature sensor acquires a second temperature inside the charging cabinet and sends the second temperature to the controller.
When the temperature inside the charging cabinet or the first temperature of the first battery is not regulated, the first temperature of the first battery and the second temperature inside the charging cabinet should be not much different for a sufficient time. When the temperature is controlled, the first temperature and the second temperature may be greatly different.
For example, when the first temperature of the first battery is low, the controller sends a discharging instruction to the first battery, and the first battery performs a discharging operation according to the discharging instruction sent by the controller, at this time, the interior of the first battery rapidly increases in temperature due to the discharging operation, the first temperature rapidly increases, and the second temperature inside the charging cabinet may not change much. Thus, the first temperature may be much greater than the second temperature.
The first temperature and the second temperature are in dynamic equilibrium, namely after a certain time, the first temperature and the second temperature can change to a range with a small difference after the temperature rising operation is not carried out. For example, when the first temperature is raised to 50 degrees and the second temperature is 10 degrees, after a period of time, it is possible that the first temperature is 18 degrees and the second temperature is 13 degrees.
Therefore, when the first temperature is less than or equal to the second preset value, the controller is specifically configured to:
sending a discharging instruction to the first battery and sending a heating instruction to the heater;
the first battery is used for executing discharging operation according to the discharging instruction, and the heater is used for executing heating operation according to the heating instruction;
the controller is also used for sending a discharging stopping instruction to the first battery and sending a heating stopping instruction to the heater when the first temperature and the second temperature are both greater than a second preset value;
the first battery is used for stopping the discharging operation according to the discharging stopping instruction, and the heater is used for stopping the heating operation according to the heating stopping instruction.
For example, when the second preset value is 10 degrees, before the temperature regulation, the first temperature is-18 degrees, the second temperature is-17 degrees, at this time, the controller sends a discharging instruction to the first battery, sends a heating instruction to the heater, the first battery performs a discharging operation according to the discharging instruction, and the heater performs a heating operation according to the heating instruction.
Because the first battery is heated up faster when the first battery is discharged, the first temperature can reach 0 ℃ more quickly. In this case, the second temperature may also be below 0 degrees, for example-10 degrees. If the discharging and heating are stopped at this time, the first battery is affected by the temperature inside the charging cabinet, and may be quickly cooled to below 0 ℃. Therefore, in the embodiment of the invention, when the first temperature and the second temperature are both greater than the second preset value, the controller sends a discharge stopping instruction to the first battery and sends a heating stopping instruction to the heater.
When both the first temperature and the second temperature are greater than 0 degrees, the first temperature rises faster, possibly higher than the second temperature, for example 20 degrees when the second temperature is 2 degrees. At this moment, the heating is stopped, even if the first temperature of the first battery is influenced by the second temperature in the charging cabinet, the first temperature of the first battery cannot be immediately reduced to be lower than 0 degree, but can be reduced to a value between 2 degrees and 20 degrees, and at this moment, the first battery can still ensure better work.
Fig. 5 is a schematic diagram of cooling the charging cabinet according to the embodiment of the present invention, and as shown in fig. 5, when the temperature of the first battery is too high, the first temperature sensor, the controller, the first battery, the air deflector, and the fan are mainly used to cool the first battery.
The first temperature sensor acquires a first temperature of the first battery and sends the first temperature to the controller. The controller obtains a first temperature of the first battery and judges whether the first temperature exceeds a certain range.
When the first temperature of the first battery is greater than or equal to the first preset value, a possible implementation manner is that the controller sends a rotation instruction to the air deflector, and the air deflector receives the rotation instruction and executes a rotation operation according to the rotation instruction sent by the controller. Because the rotation of aviation baffle can accelerate the circulation of air, when the aviation baffle carries out the rotation operation, can arrange the cabinet outside that charges with the inside high-temperature air of cabinet and heat, the low-temperature air of supplementary cabinet that charges reduces the inside temperature of the cabinet that charges, and then reduces the temperature of first battery.
Another possible implementation manner is that the controller sends a rotation instruction to the fan, and the fan receives the rotation instruction and performs a rotation operation according to the rotation instruction sent by the controller. The quantity of fan is one or more, when the fan execution rotation operation, the inside circulation of air of cabinet that charges that can be very big, will charge the inside high-temperature air of cabinet and heat and arrange the cabinet outside that charges, and the low-temperature air of the cabinet that charges is complemented, reduces the inside temperature of the cabinet that charges, and then reduces the temperature of first battery.
Optionally, when the first temperature of the first battery is less than or equal to the second preset value, the controller sends a rotation instruction to the air deflector and also sends a rotation instruction to the fan, and the air deflector and the fan rotate through the rotation instruction, so that air circulation inside the charging cabinet is accelerated more rapidly, and the temperature of the first battery is reduced more rapidly.
Optionally, the fan is an electric fan, and a power supply is needed to supply power when the fan performs rotating operation. One possible implementation is to provide a second battery in the charging cabinet, the second battery being used to supply power to the fan.
Similarly, when the temperature inside the charging cabinet or the first temperature of the first battery is not regulated, the first temperature of the first battery and the second temperature inside the charging cabinet should be not much different for a sufficient time. When the temperature is controlled, the first temperature and the second temperature may be greatly different.
For example, when the first temperature of the first battery is higher, the controller sends a rotation instruction to the fan and the air deflector, and the fan and the air deflector perform a rotation operation according to the rotation instruction sent by the controller, at this time, because the temperature inside the charging cabinet is reduced and then the temperature of the first battery is reduced through temperature transmission, the second temperature inside the charging cabinet is rapidly reduced due to the rotation operation of the fan and the air deflector, the second temperature is rapidly reduced, and the first temperature of the first battery may not change greatly. Thus, the first temperature may be much greater than the second temperature.
The first temperature and the second temperature are in dynamic equilibrium, namely after a certain time, the first temperature and the second temperature can change to a range with a small difference after the cooling operation is not carried out. For example, when the second temperature is reduced to 30 degrees, the first temperature is 50 degrees, and after a certain period of time, the second temperature may be 32 degrees and the first temperature may be 36 degrees.
Therefore, when the first temperature is greater than or equal to the first preset value, the controller is specifically configured to:
sending a rotation instruction to the fan and the air deflector;
the fan and the air deflector are used for rotating according to a rotating instruction;
the controller is also used for sending a rotation stopping instruction when the first temperature and the second temperature are both smaller than a first preset value;
the fan and the air deflector are used for stopping rotating according to the rotation stopping instruction.
For example, when the second preset value is 40 degrees, the first temperature is 50 degrees and the second temperature is 52 degrees before temperature regulation, and at this time, the controller sends a rotation instruction to the fan and the air deflector, and the fan and the air deflector perform a rotation operation according to the rotation.
Because the fan and aviation baffle rotate, the inside cooling of cabinet that charges is faster, therefore the second temperature can be more rapid reach 40 degrees. In this case, the first temperature may be 40 degrees or higher, for example, 50 degrees. If the fan and the air deflector stop rotating at the moment, the first battery is influenced by the temperature in the charging cabinet and cannot be cooled to below 40 ℃. Therefore, in the embodiment of the invention, the controller sends the rotation stopping instruction to the fan and the air deflector when the first temperature and the second temperature are both smaller than the first preset value.
When both the first temperature and the second temperature are less than 40 degrees, the second temperature is cooled down faster, possibly lower than the first temperature, for example 39 degrees when the second temperature is 30 degrees. And at the moment, the temperature is stopped to be reduced, even if the first temperature of the first battery is less influenced by the second temperature in the charging cabinet, the first temperature of the first battery is not increased to more than 40 degrees and is reduced to a value between 30 degrees and 39 degrees, and the first battery can still ensure good work.
Optionally, the controller is further configured to receive an adjustment instruction sent by the client, and adjust the first preset value and/or the second preset value according to the adjustment instruction.
The client of the user can be connected with the charging cabinet, so that the first preset value or the second preset value is adjusted. For example, when the first battery of the charging cabinet is replaced, the ideal temperature range for the operation of different first batteries may be different, at this time, an adjustment instruction may be generated to the charging cabinet through the client, and the controller adjusts the first preset value or the second preset value according to the adjustment instruction, and so on.
The charging cabinet provided by the embodiment of the invention comprises a first battery, a controller, a first temperature sensor and an air deflector, wherein the first temperature sensor is respectively connected with the first battery and the controller, the first battery is used for charging an electric vehicle, and the first temperature sensor is used for acquiring a first temperature of the first battery and sending the first temperature to the controller. After the first temperature is obtained, the controller can judge whether the first battery works within a certain temperature range according to the first temperature. When the first temperature is greater than or equal to the first preset value, the controller can control the air deflector to rotate, discharge the air with higher temperature inside the charging cabinet, absorb the air with lower temperature outside the charging cabinet, reduce the temperature inside the charging cabinet, and then reduce the temperature of the first battery inside the charging cabinet through the transmission of the temperature. When the first temperature is less than or equal to the second preset value, the controller can control the first battery to perform a discharging operation, so that the first battery generates heat energy from electric energy inside the first battery when performing a discharging operation, and the temperature of the first battery is increased. According to the charging cabinet provided by the embodiment of the invention, the first temperature of the first battery is obtained in real time through the first temperature sensor, and the temperature of the first battery is regulated and controlled through the controller when the first temperature is too high or too low according to whether the first temperature exceeds a certain range, so that the temperature of the first battery is not too high or too low, and the charging cabinet is beneficial to charging an electric vehicle.
