Detailed Description
For the sake of brevity and illustrative purposes, the principles of the present invention are described herein primarily with reference to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of devices that may be used to provide mobile charging, and that such variations do not depart from the spirit and scope of the claimed invention.
Certain exemplary embodiments will be described below with reference to the accompanying drawings. Electrical, mechanical, logical, and structural changes may be made to these embodiments without departing from the spirit and scope of the present invention. Furthermore, while a feature may have been described herein in connection with one or more of several implementations/embodiments, a feature from one embodiment may be combined with one or more other features of other implementations/embodiments. The specific embodiments described below are therefore not to be considered in a limiting sense as the subject matter of the present application.
In the description of various aspects herein, the terms "first," "second," and the like do not necessarily denote any order or priority relationship, but rather may be used to more clearly distinguish one element or time interval from another.
In an example of the present application, a vehicle (hereinafter, also referred to as a mobile charging cart in an example) serving as a mobile charging cart includes a charging port to output electric power to an electric device outside the vehicle, and a battery energy storage portion. The battery energy storage part is electrically connected with the charging port through the power distribution component. In an example of the present application, a generator of the vehicle is electrically connected to a charging port for outputting electric power to the outside. In the following example of the present application, the charging port to which the battery energy storage portion is connected and the charging port to which the vehicle generator is connected are the same charging port.
The application provides a mobile charging vehicle for providing power to an external charging facility. The external charging facility is, for example, an external device that requires electricity, such as an electric vehicle, a hybrid vehicle, or the like. The external charging facility may be an external charging pile, that is, the mobile charging cart may provide power to the device requiring power via the external charging pile.
The charging interface of the mobile charging vehicle can be a direct current charging interface and also can be an alternating current charging interface.
The mobile charging vehicle comprises an energy storage part, a generator and a charging port. By way of example and not limitation, the energy storage portion is an energy storage battery employed in the present application. The energy storage battery stores electric power and, in the event of its running out of power, can be recharged with electric power. The generator converts other forms of energy generated by the mobile charging cart into electrical energy and can output it for provision to other charging facilities. The mobile charging vehicle is in the following example a fuel-powered four-wheel drive vehicle and the energy supplied to the generator is transmitted from the engine to the generator via the transfer gear. In some examples, the energy storage battery is a replaceable battery, that is, the energy storage battery may be replaced with a charged energy storage battery in case the power of the energy storage battery is insufficient to provide power to the outside.
Fig. 1 is a schematic illustration of a mobile charging cart and a scenario in which it is used according to an example of the present invention. As shown in fig. 1, a vehicle (only components related to the present application are illustrated in the drawing) serving as a mobile charging vehicle is exemplified by, but not limited to, a fuel-powered four-wheel drive vehicle. According to an example of the present application, the charging vehicle includes a charging interface, the energy storage portion 100. The energy storage portion 100 is electrically connected to the charging interface to provide power to the external electric device through the charging interface. According to the present application, the generator 202 of the charging vehicle may also provide power to the external electrical device.
According to some examples of the present application, a rectifier 204 is provided between the generator 202 and the charging port to perform a rectification process on the output power before the power of the generator 202 is output to the charging port. For example, to convert alternating current generated by the generator 202 into direct current. A DC/DC converter 102 is provided between the energy storage portion 100 and the charging port to convert the power of the energy storage portion 100 into power suitable for an external charging facility before being output to the charging port. For example, a higher voltage dc is converted to a lower voltage dc.
According to still other examples of the present application, the energy storage portion 100 has more than one energy storage battery, and thus a switching unit for switching between the energy storage batteries may be provided between each energy storage battery and the charging interface. For example, if only one or more batteries in the energy storage portion 100 need to be used when outputting power externally, only the corresponding switch unit is turned on. In this case, a switching unit that switches between the energy storage batteries is provided between the energy storage batteries and the DC/DC converter.
In some cases, it may be possible to provide, for example, a DC/DC converter between each energy storage battery and the charging interface. There are also cases where one DC/DC converter may be provided for a plurality of energy storage cells together.
When referring to an energy storage battery in the above example, it should be understood that the battery is a combination of a plurality of battery units, that is, a battery storage component formed by a plurality of battery units electrically connected to each other as a power battery, and the battery storage component thus formed has a certain battery storage capacity. In some cases, one energy storage battery corresponds to one power battery of the electric vehicle.
In some examples of the present application, the charging port may include a first charging port for the energy storage portion and a second charging port for the generator, that is, the energy storage portion 100 supplies power to the outside through the first charging port, and the generator 202 supplies power to the outside through the second charging port.
Returning to fig. 1, in this particular example, the generator 202 provides power to the external electrical device using the same charging interface as the energy storage portion 100. In this example, an electric power distribution unit 300 is further disposed between the energy storage portion 100, the generator 202 and the charging interface, and electrically connects one of the battery energy storage portion 100 and the generator 202 with the charging interface according to the received control signal, so that the external electric device is charged only by one of the battery energy storage portion 100 and the generator 202 in the same time period. According to this example, a transfer case (hereinafter also referred to as a transfer case) 201 transfers energy received from the engine of the fuel-charged vehicle to a generator 202, and the generator 202 converts the received energy into electric energy. It should be noted that in the present application, the fuel vehicle is used as a charging vehicle, so that the energy output by the engine is primarily provided to the generator 202, which converts the energy into electric energy, when the basic operation of the fuel vehicle is satisfied. The power output from the generator 202 is first passed through the rectifier 204 to convert the current to dc power, which may be implemented in the rectifier 204 module or separately, if other conversions are desired. The output of the battery energy storage unit 100 is converted into a current of a magnitude required by the external electric device by the DC/DC converter 102, and then output to the external electric device.
In this example of the application, the rectifier 204 and the DC/DC converter 102 are both controlled by the controller 502 to enable the output of the rectifier 204 and the DC/DC converter 102 to be tailored to the requirements of the external consumer. As an example, a battery manager (also potentially other names) of an external powered device can communicate with the controller 502 to make the controller 502 aware of the external powered device's requirements, e.g., requirements for current, voltage, etc. In some more specific examples, the controller 502 further includes a rectification controller 502-1 and a DC/DC controller 502-2, such that the rectification controller 502-1 and the DC/DC controller 502-2 control the rectifier 204 and the DC/DC converter 102, respectively. This is merely an example and these control functions may all be integrated in the same controller.
The present invention will be described by taking an external power consumer as an example of a vehicle. With continued reference to fig. 1, the external power consumption device 400 is a vehicle, which may be a pure electric vehicle or a hybrid vehicle. The vehicle 400 is charged by a mobile charging vehicle according to an example of the present application. In some examples, prior to charging, a battery manager (not shown) of the vehicle 400 communicates with the charging controller 502 of the mobile charging cart to make the mobile charging cart aware of the need for charging parameters by the vehicle 400. Here, the charging parameter may be one or more of a current level, a charge amount demand, and a charging demand, which are not listed herein.
The charge controller 502 determines whether the vehicle 400 is supplied with power from the battery storage portion 100 or the generator 202, depending on the communication result. If it is determined that the battery energy storage portion 100 supplies power, the power distribution unit 300 may electrically connect the battery energy storage portion 100 and the charging interface, for example, close the switch 301; conversely, if it is determined that the vehicle 400 is being powered by the generator 202, then the power distribution unit 300 will connect the generator 202 to the charging port, e.g., switch 302 is closed. As an example, in the case where the battery energy storage portion 100 supplies power to the vehicle, the electric power of the battery energy storage portion 100 is first converted into electric power suitable for the vehicle 400 via the DC/DC converter 102 and then output to the vehicle 400 via the current distribution unit 300.
The selection of the battery storage 100 or the generator 202 to provide the electrical output to the vehicle 400 may employ different mechanisms, depending on the actual application scenario. As an example, in the present application, for example, in the case where the electric power of the battery energy storage portion 100 is sufficient to meet the electric power demand of the vehicle 400, the battery energy storage portion 100 is preferentially employed for charging; in the case where the power of the battery energy storage portion 100 is not enough to meet the power demand of the vehicle 400, a part of the power may be provided by the battery energy storage portion 100, and the rest of the power may be switched to be provided by the generator 202; or in the case where the power at the generator 202 is sufficient to meet the demand of the vehicle 400, then it is provided entirely by the generator 202.
For example, in the case where the power of the energy storage portion 100 is insufficient, the generator 202 may charge the energy storage portion to supplement the power, for example, in the case where there is no power demand from the external electric device. However, this is not a limitation, and in case the generator 202 has sufficient power, it can simultaneously supply power to the energy storage portion 100 and the external power demand device. In both cases described herein, the power distribution unit 300 may be slightly different from that shown in fig. 1, such as adding a switch between the switch 302 and the charging port.
In the above example of the present application, the power distribution unit 300 further includes a switch 303, and when the switch 303 is turned on, the energy storage portion 100 can be connected to an external power source to be charged.
In the above specific examples of the present application, in the case that there are a plurality of energy storage batteries, each energy storage battery may select the same battery, and the same battery refers to the same capacity, voltage range, and the same material of the battery.
It is mentioned above that the charging interface may also be used for providing power to an external charging post. And different electric power can be provided according to the difference of the required electric power of charging stake, for example, alternating current power or direct current power, etc. It should be understood that in the case of providing power to an external charging post, the charging controller 502 is capable of establishing communication with the controller of the charging post to receive charging parameter information.
In all examples herein where a charging controller 502 is mentioned, the controller obtains charging parameters by communicating with an external charging facility. It should be noted that the communication with the external charging facility may be determined by the controller communicating with a remote controller of the external charging facility, such as a cloud-end controller.
According to some examples of the present invention, the mobile charging cart may further include a battery detection module for detecting a state of charge SOC, a state of health SOH, and the like of the battery in the energy storage portion 100, so as to ascertain the state of the energy storage portion 100.
The application also provides a charging management method used in the mobile charging vehicle. The charging vehicle comprises a first power supply part and a second power supply part. According to the method, after communication is established between the mobile charging vehicle and an external charging facility, charging parameter information is obtained from the external charging facility; with reference to the charging parameter information, a manner of supplying power to the external charging facility through the first power supply part and the second power supply part is determined, the manner including supplying power only through the first power supply part, supplying power only through the second power supply part, or supplying power sequentially by the first power supply part and the second power supply part. With reference to this charging parameter information, the power output is adjusted to the demand of the external charging facility in any manner of supplying power to the external charging facility. The charging parameter information is, for example, one or more of dc charging or ac charging, charging current level, charging amount, and charging time.
As an example, the mobile charging cart is, for example, the mobile charging cart described in the above examples. The first power supply unit is, for example, the energy storage unit 100, and the second power supply unit is, for example, the generator 202. The following further describes a charging management method according to an example of the present application with reference to fig. 1 and fig. 2.
In step S1, the charging controller 502 of the mobile charging vehicle establishes communication with the electric vehicle 400 to acquire charging parameter information of the electric vehicle 400.
In step S3, it is determined whether the power is supplied from the energy storage portion 100 or the power generator 202, or both are supplied in sequence, with reference to the acquired charging parameter information. The selection of which mode to provide power may take into account the demand of the external charging facility and the current power conditions of the energy storage 100 and the generator 202. For example, if the charging parameter information indicates that the charging unit 400 requires rapid charging and the demand for the amount of charge is within the range available from the energy storage portion 100, the energy storage portion 100 is selected to provide power. In the case where the power of the battery energy storage portion 100 is not enough to meet the power demand of the vehicle 400, a part of the power may be provided by the battery energy storage portion 100, and the rest of the power may be switched to be provided by the generator 202.
In step S5, a control signal is issued according to the charging method determined in step S3. Specifically, if it is determined that the energy storage unit 100 supplies the electric power to the vehicle 400, the electric power distribution unit 300 is controlled to operate so that the energy storage unit 100 is electrically connected to the charging port; if it is determined that the generator 202 is supplying the electric power to the vehicle 400, the electric power distribution unit 300 is controlled to act so that the generator 202 is turned on with the vehicle 400. If the power output is sequentially supplied from the energy storage unit 100 and the generator 202, the power distribution unit 300 is controlled to operate so that the energy storage unit 100 and the generator 202 are sequentially connected to the charging port.
