Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

The charging pile is usually used as an energy supply device of the electric automobile and can rapidly charge a storage battery of the electric automobile. Because electric automobile fills electric pile and has obtained a large amount of laying at present, consequently utilize current electric automobile to fill electric pile and charge low-speed electric vehicle such as electric motorcycle, electric bicycle and electric tricycle, will solve the difficult problem of charging of low-speed vehicle user.

Referring to fig. 1, a schematic diagram of a general charging process in the related art is shown. As shown in fig. 1, the whole process of charging the electric vehicle by using the charging pile comprises six stages: the method comprises the steps of physical connection completion, low-voltage auxiliary power-on, a charging handshake phase, a charging parameter configuration phase, a charging phase and a charging end phase.

The charging handshaking stage is divided into a handshaking starting stage and a handshaking identification stage, when the physical connection between the charging pile and the electric automobile is completed and the charging pile is electrified, the low-voltage auxiliary power supply is started, the handshaking starting stage is started to send a handshaking message, and then insulation monitoring is carried out. And entering a handshake identification stage after insulation monitoring is finished, and sending identification messages by the two parties to determine necessary information of the charging pile and the electric automobile.

After the charging handshake phase is completed, the charging pile and the electric automobile enter a charging parameter configuration phase. At this stage, the charging pile sends a message of the maximum output capacity of the charging pile to the electric automobile, and the electric automobile judges whether the charging can be carried out according to the maximum output capacity of the charging pile.

And after the charging configuration stage is completed, the charging pile and the electric automobile enter the charging stage. In the whole charging stage, the electric automobile sends the battery charging demand to the charging pile in real time, and the charging pile adjusts the charging voltage and the charging current according to the battery charging demand so as to ensure that the charging process is normally carried out. In the charging process, the charging pile and the electric automobile send respective charging states. In addition, the electric vehicle can send information such as specific state information of the power storage battery 1012, voltage and temperature to the charging pile according to requirements.

The electric automobile judges whether to finish charging according to whether the charging process is normal, whether the battery state reaches the charging finishing condition set by the electric automobile and whether a charging stopping message of the charging pile is received; and the charging pile judges whether to finish charging according to whether a charging stopping instruction is received, whether the charging process is normal, whether a manually set charging parameter value is reached or not, or whether an electric automobile charging stopping message is received or not.

And after the charging pile and the electric automobile stop charging, the charging end stage is started. At this stage, the electric automobile sends charging statistical data in the whole charging process to the charging pile, wherein the charging statistical data comprises an initial SOC, a final SOC, a lowest voltage and a highest voltage of the battery; and after receiving the charging statistical data of the electric automobile, the charging pile sends information such as output electric quantity, accumulated charging time and the like in the whole charging process to the electric automobile, and finally stops outputting the low-voltage auxiliary power supply.

By above-mentioned charging process can see, before using to fill electric pile pair or the charging process, electric automobile need carry out a series of information interaction with filling electric pile. In some possible embodiments, the electric vehicle further needs to receive a series of tests of the charging pile, such as a test of the battery voltage.

It can be understood that if the existing charging pile is adopted to charge low-speed electric vehicles such as electric bicycles, electric motorcycles, electric tricycles and the like, the low-speed electric vehicles such as the electric bicycles, the electric motorcycles, the electric tricycles and the like cannot be matched with the charging pile to complete related information interaction and detection, and the charging pile refuses to output power according to the existing protocol.

In addition, in general, the output voltage and current of the charging pile are large, and the charging voltage and current required for the low-speed electric vehicle are small, so the output voltage and current of the charging pile are not suitable for the low-speed electric vehicle.

To solve the above problem, the embodiment of the application provides an electric device based on charging of charging pile, and this electric device can directly utilize electric automobile's the electric pile of charging to charge, need not to do any transformation to the electric pile of charging, describes in detail below.

Referring to fig. 2, a schematic view of an application scenario provided in the embodiment of the present application is shown. In this application scenario, a charging post 102 and an electric device 101 are shown, through which charging post 102 can directly charge electric device 101. Wherein, should fill electric pile 102 and fill electric pile for electric automobile, this electric equipment 101 is electric bicycle.

When needs charge, can drive into this electric bicycle and fill the place that electric pile 102 belonged to, then will fill electric pile 102's the rifle that charges and insert electric bicycle's corresponding interface that charges, start the charging process, until electric bicycle's full charge.

It is to be understood that fig. 2 is merely an exemplary illustration and should not be taken as a limitation on the scope of the present application. For example, the charging pile can be a charging pile of other product types besides the charging pile of the electric automobile; in addition to electric bicycles, the electric device 101 can be used to charge other low-speed electric vehicles such as electric motorcycles, electric tricycles, and the like. Of course, besides the low-speed electric vehicle, other electric devices 101 may be charged, such as a scooter, an aircraft, and the like, which is not limited by the embodiment of the present application.

The charging principle of the electromotive device 101 will be described in detail below.

Referring to fig. 3, a schematic structural diagram of an electric device provided in an embodiment of the present application is shown. As shown in fig. 3, the electric device 101 includes a device main body 1011, and the device main body 1011 is provided with a battery 1012, a charging interface 1013, a communication module 1014, and a power conversion module 1015. The storage battery 1012 is configured to supply power to the electric device 101, and the charging interface 1013 is configured to be connected to a power output interface of the charging pile 102, so as to implement physical connection between the charging pile 102 and the electric device 101.

It is understood that the device body 1011 may be a support structure of the electric device 101 and a collection of functional modules such as a power unit and a moving unit provided on the support structure. Taking an electric bicycle as an example, the device body 1011 of the electric bicycle may be a frame, a motor provided on the frame, a wheel, a transmission, and the like. Of course, for other power equipment, there is a corresponding equipment body 1011, and the specific structure or function of the equipment body 1011 is not limited in the embodiments of the present application.

In an alternative embodiment, the charging post 102 may be an electric vehicle charging post. It can be understood that the charging pile 102 for the electric vehicle charging is specially used, and the corresponding communication protocol or detection verification and the like are set according to the application scene of the electric vehicle. Such as charging handshaking, charging parameter configuration, etc. Under the general condition, electric automobile fills and is equipped with the plug of filling soon on the electric pile, and electric automobile is last to be equipped with corresponding socket that fills soon, and during the charging, will fill soon the plug and insert on electric automobile's the socket that fills soon, realize filling electric pile and electric automobile's physical connection.

In this embodiment of the application, in order to facilitate the connection with the quick charging plug of the charging pile 102, the charging interface 1013 of the electric device 101 may be set as a quick charging socket matched with the quick charging plug, so as to implement the physical connection with the charging pile 102. It is understood that the quick charge plug and the quick charge receptacle may be interfaces that meet relevant industry standards. For example, GBT20234.3-2015 "connection device for conductive charging of electric vehicle, part 3: and (4) the standard requirement of direct current charging interface. Of course, a person skilled in the art may design the quick charging plug and the quick charging socket as interfaces meeting other standards or as dedicated interfaces according to actual needs, and the embodiments of the present application do not specifically limit this.

In addition, the above application scenario is only an exemplary description, and should not be taken as a limitation to the scope of the present application. For example, the charging pile can be a charging pile of other product types besides the charging pile of the electric automobile; if the power output interface of the charging pile 102 is a quick charging socket, the charging interface 1013 of the electric device 101 may be a quick charging plug corresponding to the quick charging socket, or the like.

In an alternative embodiment, the charging post 102 may be a dc charging post or an ac charging post. When the charging pile 102 is a direct-current charging pile, the quick charging plug of the charging pile 102 is a direct-current quick charging plug, and the charging interface 1013 of the electric device 101 is a direct-current quick charging socket; when the charging pile 102 is an ac charging pile, the quick charging plug of the charging pile 102 is an ac quick charging plug, and the charging interface 1013 of the electric device 101 is an ac quick charging socket.

In the specific implementation, during charging, after the power output interface of the charging pile 102 is connected to the charging interface 1013 of the electric device 101, the power output by the charging pile 102 can reach the storage battery 1012 to charge the storage battery 1012 through the power output interface and the charging interface 1013 of the electric device 101.

However, according to the design rule of the charging pile 102, after the physical connection is completed, the charging pile 102 needs to perform a series of information interaction and/or detection, and after the device connected to the charging pile 102 for charging is determined to be a device meeting the relevant requirements, the power supply is output. That is, after the physical connection is completed, the charging post 102 does not output power to charge the storage battery 1012 immediately.

Because the electric device 101 itself cannot cooperate with the charging pile 102 to complete related information interaction and/or detection, a communication module 1014 is added to the electric device 101 provided in the embodiment of the present application, and the communication module 1014 cooperates with the charging pile 102 to perform information interaction and/or detection. The "cooperation" may be understood as that, according to a communication protocol or a detection rule of the charging pile 102, related data or function modules meeting the verification of the communication protocol or the detection rule are built in the communication module 1014, and are used for responding to a request message or a detection action sent by the charging pile 102, and after information interaction and/or detection with the charging pile 102 is completed, enabling the power output interface of the charging pile 102 to output power.

For example, the information interaction includes charging handshaking and charging parameter configuration between charging pile 102 and communication module 1014; the detection includes the charging pile 102 detecting the voltage of the battery 1012. It can be understood that, because the storage battery 1012 of the electric device 101 is small, the voltage thereof cannot meet the detection requirement of the charging pile 102 in general, and for this problem, a high-voltage module may be built in the communication module 1014, and a high voltage may be generated instantaneously to meet the detection requirement of the charging pile 102.

After the communication module 1014 cooperates with the charging pile 102 to complete information interaction and/or detection, the power output interface of the charging pile 102 outputs power. It should be noted that, at this time, the power output by the power output interface of the charging pile 102 is a power matched with the charging parameters related to the electric vehicle, and therefore, the output power of the power output interface of the charging pile 102 needs to be adjusted.

The power conversion module 1015 is configured to convert a first output power output by the power output interface of the charging pile 102 into a second output power, and charge the storage battery 1012 of the electric device 101 according to the second output power, where the second output power is matched with the charging parameter of the storage battery 1012. It is understood that the communication module 1014 may store therein a charging parameter associated with the storage battery 1012, and the power conversion module 1015 may adjust the power of the power source to the corresponding second output power according to the charging parameter. Specifically, when the charging pile 102 is a DC charging pile 102, the power conversion module 1015 may be a DC/DC converter. Of course, the power conversion module 1015 may also adopt other implementation manners, and the embodiment of the present application does not limit the specific implementation manner thereof.

It can be understood that when the charging post 102 is an electric vehicle charging post and the electric device 101 is a low-speed electric vehicle (which can also be understood as a low-power electric vehicle), the output power of the charging post 102 needs to be reduced, that is, the second output power is smaller than the first output power, because the output power of the electric vehicle charging post is larger and the required power for charging the storage battery 1012 of the electric device 101 is smaller. However, in some special application scenarios, it may be necessary to increase the output power of charging pile 102, and this is not limited by the embodiment of the present application.

In one possible implementation, when the electric device 101 is a low-speed electric vehicle, the voltage corresponding to the second output power is 36-120V, for example, 36V, 48V, 60V, 72V, or the like; the current corresponding to the second output power is greater than or equal to 10A.

As shown in fig. 3, the electric device 101 according to the embodiment of the present application is an electric bicycle. It is understood that besides electric bicycles, other low-speed electric vehicles such as electric motorcycles, electric tricycles and the like, or other existing or future developed electric vehicles can be used. Of course, besides the low-speed electric vehicle, other electric devices, such as a scooter, an aircraft, etc., may be charged, which is not limited by the embodiment of the present application.

In one possible implementation, the storage battery 1012 and the charging interface 1013 are provided in a rear seat region of the electric bicycle, the electric motorcycle, and/or the electric tricycle; the communication module 1014 is disposed in a direction control unit area of the electric bicycle, the electric motorcycle, and/or the electric tricycle; the power conversion module 1015 is disposed in a pedal area of the electric bicycle, the electric motorcycle, and/or the electric tricycle.

Of course, those skilled in the art may set each functional module at other positions of the device body 1011 according to actual needs, and the embodiment of the present application does not limit this.
