The new energy automobile is driven by electric energy, and when the electric quantity of a battery on the new energy automobile is low or exhausted, the new energy automobile needs to be charged. Fig. 1 is a scene schematic diagram that new energy automobile charges that prior art provided, as shown in fig. 1, when new energy automobile need charge, the driver need drive the electric pile that fills that sets up toward charging station, parking area etc. with new energy automobile, will fill on electric pile the rifle that charges and the new energy automobile with the interface connection that charges that the rifle matches that charges for new energy automobile.
However, when the new energy automobile cannot be driven to the vicinity of the charging pile for charging due to insufficient battery power, the new energy automobile may not continue to run due to insufficient battery power.
The embodiment of the invention provides a mobile charging device which can be moved and has a charging function, so that when the device to be charged needs to be charged, the mobile charging device can be moved to the device to be charged to charge the device to be charged.
The technical solution of the present invention is explained in detail by some examples below. The following several embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic structural diagram of a mobile charging apparatus according to an embodiment of the present invention, and as shown in fig. 2, the mobile charging apparatus may include a movable carrier 100, a box 200, an energy storage device 11, a power conversion device 12, and a control device 13. The case 200 is fixed to the movable carrier 100.
When the movable carrier 100 of the mobile charging device is a terrestrial movable carrier (e.g., a vehicle, etc.), the mobile charging device may charge a device to be charged (e.g., a new energy automobile) on the land; when the movable carrier 100 of the mobile charging device is a water movable carrier (e.g., a boat), the mobile charging device may, for example, charge a device to be charged (e.g., a motorized boat) on water; when the movable carrier 100 of the mobile charging device is an aerial movable carrier (e.g., an aircraft), the mobile charging device may charge an aerial device to be charged (e.g., an electric aircraft). That is, the form of the movable carrier 100 in the present embodiment corresponds to the applicable scene, and the form of the movable carrier can be set according to the actual scene, and the embodiment shown in fig. 1 is described by taking the movable carrier 100 as a vehicle as an example.
The case 200 may be connected to the movable carrier 100 by a connector such that the case 200 is fixed to the movable carrier 100. In the example shown in fig. 1, the enclosure 200 is a container enclosure, and the movable carrier 100 may include a tractor head and a frame chassis to which the container enclosure is secured. In this embodiment, the housing 200 forms a receiving space therein.
The energy storage device 11, the power conversion device 12, and the control device 13 are fixed in the case 200. The positions of the energy storage device 11, the power conversion device 12, and the control device 13 in the box 200 may be set according to actual conditions.
The control device 13 is connected to the energy storage device 11 and the power conversion device 13, and the control device 13 may be connected to the energy storage device 11 and the power conversion device 13 through a serial port, an RJ-45, or other wired connection. The energy storage device 11 is connected to the power conversion device 12 via a dc bus.
The energy storage means 11 may be, for example, a charging capacitor, a charging battery, or the like, and may be used for storing electrical energy. The power conversion device 12 may be any device having a voltage conversion function, for example. In the present embodiment, the power conversion device 12 is located between the energy storage device 11 and the device to be charged. That is, the energy storage device 11 is connected to the charging interface of the device to be charged through the power conversion device 12.
The control device 13 may be any electronic device having processing, controlling, and the like functions, and is used for controlling the energy storage device 11 and the power conversion device 12 to implement corresponding functions.
And a control device 13, configured to send a first charging signal to the power conversion device 12 when the power conversion device 12 is connected to the charging interface of the device to be charged. For example, the power conversion apparatus 12 may send a signal of successful connection to the control apparatus 13, or the control apparatus 13 may check whether the power conversion apparatus 12 is connected to the charging interface of the device to be charged in a periodic polling manner. The first charging signal may be, for example, encapsulated in a message and sent by the control device 13 to the power conversion device.
And the power conversion device 12 is configured to convert the output voltage of the energy storage device 11 into a charging voltage of the device to be charged according to the first charging signal, and output the charging voltage to the device to be charged. The voltage conversion may be from low voltage to high voltage, or from high voltage to low voltage, depending on the relationship between the dc voltage output by the energy storage device 11 and the charging voltage of the device to be charged. For example, the power conversion apparatus 12 may interact with the device to be charged through a charging interface of the device to be charged, and determine a charging voltage of the device to be charged; alternatively, the power conversion apparatus may determine the charging voltage of the device to be charged through the first charging signal. At this time, different charging signals correspond to different charging voltages; alternatively, the power conversion device 12 may receive a charging voltage to be charged, which is input or selected by a user. Of course, the power conversion device 12 may obtain the charging voltage of the device to be charged in other manners, which is not limited to this.
It should be understood that when the power conversion apparatus 12 is connected to the charging interface of the device to be charged and the control apparatus 13 does not send the first charging signal to the power conversion apparatus 12, the power conversion apparatus 12 is in the open circuit state at this time, and the voltage conversion operation is not performed. For example, a circuit breaker (e.g., an ac circuit breaker) may be provided inside the power conversion device 12. When the power conversion device 12 receives the first charging signal, the circuit breaker of the power conversion device 12 is closed to perform an operation of converting the output voltage of the energy storage device 12 into a charging voltage of the device to be charged.
For example, taking the movable carrier 100 as a vehicle and the device to be charged as a new energy automobile as an example, when the new energy automobile cannot run due to insufficient battery power, the mobile charging device may drive to a location where the new energy automobile is located, and connect the power conversion device 12 with a charging interface of the new energy automobile. After the power conversion device 12 is connected with the charging interface of the new energy automobile, the control device 13 sends a first charging signal to the power conversion device 12, and the power conversion device 12 may control a circuit breaker in the power conversion device to be turned on according to the first charging signal, so as to turn on a dc bus and the charging interface of the device to be charged, convert the dc voltage output by the energy storage device 11 into the charging voltage of the device to be charged, and output the charging voltage to the device to be charged. In this example, when new energy automobile can't travel because the electric quantity is not enough, remove battery charging outfit and can drive to new energy automobile position, charge new energy automobile to realize emergency rescue, make new energy automobile can continue to travel.
According to the mobile charging equipment provided by the embodiment of the invention, when the to-be-charged equipment is insufficient in electric quantity, the mobile charging equipment can be moved to the vicinity of the to-be-charged equipment by the movable carrier, the power conversion device is connected with the to-be-charged equipment, and the electric energy in the energy storage device is output to the to-be-charged equipment under the control of the control device, so that the problem that the to-be-charged equipment is insufficient in electric quantity of a battery is solved.
Fig. 3 is a schematic structural diagram of another mobile charging apparatus according to an embodiment of the present invention, and as shown in fig. 3, the mobile charging apparatus further includes a temperature adjustment device 14; the temperature adjusting device 14 is fixed in the case 200 and connected to the control device 13 to adjust the temperature of the case by the temperature adjusting device 14. The temperature adjustment device 14 may be, for example, an air conditioner.
The first mode is as follows: the temperature of the box is adjusted according to the ambient temperature, specifically:
the control device 13 is further configured to send an activation signal to the temperature adjustment device 14 when the ambient temperature is not within the preset temperature range. For example, the control device 13 may encapsulate the activation signal in a message and send the message to the thermostat 14.
And the temperature adjusting device 14 is used for adjusting the temperature in the box body to a preset temperature value, and the preset temperature value is within a preset temperature range. The preset temperature range may be an operating temperature range of the energy storage device 11, and the preset temperature range may also be included in the operating temperature range of the energy storage device 11. The ambient temperature may be a temperature inside the case, or may also be a temperature outside the case, or a temperature of an environment in which the mobile charging device is currently located.
For example, assume that the preset temperature range is 5 degrees celsius to 20 degrees celsius and the preset temperature value is 15 degrees celsius. When the ambient temperature is minus 5 degrees centigrade, the control device 13 sends a start signal to the temperature adjustment device 14, so that the temperature adjustment device 14 increases the temperature from minus 5 degrees centigrade to 15 degrees centigrade. When the ambient temperature is 30 degrees celsius, the control device 13 sends an activation signal to the temperature adjustment device 14, so that the temperature adjustment device 14 adjusts the temperature from 30 degrees celsius to 15 degrees celsius.
In a possible implementation manner, the temperature adjusting device 14 may have a temperature detecting function, and the control device 13 may use the temperature in the box detected by the temperature adjusting device 14 as the ambient temperature to determine whether the ambient temperature is within the preset temperature range.
In another possible implementation, the mobile charging device further comprises a temperature sensor 15; the temperature sensor 15 is connected to the control device 13 for measuring the ambient temperature. In this way, the control device 13 can determine whether the ambient temperature is within the preset temperature range based on the ambient temperature measured by the temperature sensor 15. For example, the temperature sensor 15 may be fixed inside the case, or the temperature sensor 15 may be fixed outside the case, or the temperature sensor 15 may be disposed on the movable carrier 100.
Of course, the control device 13 may acquire the ambient temperature in other manners, which is not limited to this.
When the ambient temperature is too low (for example, the temperature is low in winter), the energy storage device 11 is in a low-temperature power limiting state, so that the device to be charged cannot be charged. By means of the present embodiment, it is possible to avoid the energy storage device 11 being in a low temperature power limited state. Correspondingly, the energy storage device 11 can be prevented from being in a working environment with overhigh temperature, so that the performance of the energy storage device 11 can be guaranteed, and the service life of the energy storage device 11 can be prolonged.
The second mode is as follows: adjust the temperature of box according to the moment of predetermineeing, specifically:
the control device 13 is further configured to send an activation signal to the thermostat 14 when the preset time is reached.
And the temperature adjusting device 14 is used for adjusting the temperature in the box body to a preset temperature value.
For example, assume that the preset temperature value is 15 degrees celsius and the preset time is 01: 15. When 01:15 is reached, the control device 13 sends an activation signal to the thermostat 14 to cause the thermostat 14 to adjust the temperature to 15 degrees celsius.
In a possible implementation manner, the control device 13 has a timing function, and the control device 13 may determine whether the preset time is reached based on its own timing, so as to implement the embodiment.
In other possible implementations, the mobile charging device may further include a timing apparatus 16; the timing device 16 is fixed in the box body, and the timing device 16 is connected with the control device 13.
And a timing device 16, configured to send a timing signal to the control device 13 when the preset time is reached, where the timing signal is used for indicating the preset time. The timing means 16 may be, for example, a timer. In this way, the control device 13 can implement this embodiment according to the preset time indicated by the timing signal sent by the timing device 16.
For example, fig. 4 is a schematic structural diagram of another mobile charging device provided in the embodiment of the present invention. As shown in fig. 4, the timing device 16 may include a battery 161 (for example, a 24V battery) and a timing relay 162, and the timing relay 162 is connected to the battery 161 and the control device 13, respectively. The battery 161 serves as a starting power supply for supplying power to the control device 13, and the timing relay 162 may preset a starting time. When the time reaches the preset time, the timing relay 162 is turned on, the storage battery 161 supplies power to the control device 13, and the control device 13 is started, so that the corresponding function is realized.
Of course, the control device 13 may determine whether the preset time is reached by other manners, for example, the user sends a timing signal to the control device 13 remotely through a terminal, which is not limited thereto.
For example, in the case of charging a new energy bus by using a mobile charging device, the new energy bus usually needs to start charging at a fixed time at night. When the temperature is low at night, the energy storage device 11 is prone to low temperature power limiting. In order to guarantee that the new energy bus can be charged in time at the preset moment (namely the fixed charging moment of the new energy bus), the temperature adjusting device is started at the preset moment to enable the energy storage device 11 to work normally, so that the mobile charging equipment can charge the new energy bus. Correspondingly, when the night temperature is higher, the temperature adjusting device can be started at the preset moment in the above mode, so that the mobile charging equipment can charge for the new energy bus.
The third mode is as follows: adjust the temperature of box according to preset moment and ambient temperature, specifically:
and the control device 13 is further configured to send a start signal to the temperature adjustment device when the preset time is reached and the ambient temperature is not within the preset temperature range.
And the temperature adjusting device 14 is used for adjusting the temperature in the box body to a preset temperature value.
For example, assume that the preset temperature range is 5 degrees celsius to 20 degrees celsius, the preset temperature value is 15 degrees celsius, and the preset time is 01: 15. When the temperature reaches 01:15 and the ambient temperature is 15 ℃, the control device 13 does not send a starting signal to the temperature adjusting device 14; when the temperature reaches 01:15 and the ambient temperature is minus 5 ℃, the control device 13 sends a starting signal to the temperature adjusting device 14, so that the temperature adjusting device 14 increases the temperature from minus 5 ℃ to 15 ℃; when the temperature reaches 01:15 and the ambient temperature is 30 ℃, the control device 13 sends a starting signal to the temperature adjusting device 14, so that the temperature adjusting device 14 reduces the temperature from 30 ℃ to 15 ℃.
In this embodiment, the control device combines the preset time and the ambient temperature, so as to ensure the accuracy of temperature adjustment.
Fig. 5 is a schematic structural diagram of another mobile charging apparatus according to an embodiment of the present invention, and as shown in fig. 5, the power conversion device 12 may include a charging gun 121.
The charging gun 121 is used for being connected with a charging interface of a device to be charged.
The control device 13 is specifically configured to output a charging voltage to the device to be charged through the charging gun 121.
The power conversion device 12 may be configured with multiple types of charging guns, and the different types of charging guns may be matched with different types of charging interfaces, so that the mobile charging device may charge different types of devices to be charged. As will be appreciated by those skilled in the art, the charging gun 121 can be used in cooperation with a charging interface of a device to be charged, so as to output a charging voltage to the device to be charged through the charging gun 121.
In another possible implementation manner, the power conversion device 12 may include an accessory capable of being connected to a charging interface of the device to be charged, and after the accessory is connected to the charging interface, the control device 13 may output the charging voltage to the device to be charged through the accessory. The accessory can also be independent of the power conversion device 12, via which the power conversion device is connected to the charging interface of the device to be charged.
In another possible implementation manner, the device to be charged includes a charging gun, the power conversion device 12 is provided with a charging interface capable of being connected to the charging gun of the device to be charged, and when the charging gun of the device to be charged is connected to the charging interface of the power conversion device 12, the control device 13 may output the charging voltage to the device to be charged through the accessory.
With continued reference to fig. 5, in some possible implementations, the power conversion device 12 also includes an ac interface 122.
The control device 13 is further configured to send a second charging signal to the power conversion device 12 when the ac interface 122 is connected to the external ac power source. The external ac power source may be, for example, ac power of a power grid, that is, the input voltage of the external ac power source is ac power. The second charging signal may be, for example, encapsulated in a message and sent by the control device 13 to the power conversion device 12.
The power conversion device 12 is further configured to convert an input voltage of the external ac power source into a charging voltage of the energy storage device 11 according to the second charging signal, and output the charging voltage to the energy storage device 11. Here, the charging voltage of the energy storage device 11 is a dc voltage. That is, the power conversion device 12 also has a rectifying function to convert ac power into dc power and charge the energy storage device 11 when the external ac power supply charges the energy storage device 11 through the ac interface 122.
In some application scenarios, the energy storage device 11 needs to be discharged for maintenance reasons and the like.
