Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with aspects of the utility model.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the utility model. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

In the related art, the charging modes of the vehicle can be classified into a "fast charging" mode and a "slow charging" mode. For the former, the complete charging procedure may be "household 220v16A socket → charging cord → slow charging port → vehicle-mounted charger (i.e., OBC) → battery pack". The electric energy used for charging is low-voltage alternating current which is output by the OBC after the OBC converts the high-voltage direct current of the battery pack and is output outwards, so that the problem of lower vehicle charging efficiency in the scheme is caused; for the latter, the complete charging flow can be "fast charging pile→charging wire→fast charging port→battery pack", wherein the interior of the charging pile has converted electric energy into high-voltage direct current required by the vehicle, thus avoiding participation of OBC, and enabling the vehicle to directly store the high-voltage direct current output by the charging pile into the battery pack, thereby realizing the effect of fast charging. The two charging modes also lead to the difference of the charging interfaces, and the charging output interface and the charging input interface related in the specification can be used as the charging interfaces corresponding to the quick charging modes, thereby providing a technical foundation for realizing the efficient charging mode of 'vehicle-to-vehicle'.

Embodiments of the vehicle-to-vehicle charging apparatus of the present utility model are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of a vehicle-to-vehicle charging system according to an embodiment of the disclosure. The dynamic display system may include an powered vehicle 11, a vehicle to be powered 12, and a vehicle-to-vehicle charging device 13.

The energy supply vehicle 11 is a vehicle that outputs electric energy to the outside, and in the running process of the system, the energy supply vehicle 11 connects its charging interface with the charging input interface of the vehicle-to-vehicle charging device 13 through the first charging circuit, and transmits electric energy to the vehicle 12 to be supplemented through the charging output interface of the vehicle-to-vehicle charging device 13.

The vehicle to be supplemented 12 is a vehicle that receives electric energy and charges, and in the running process of the system, the energy-supplying vehicle 11 connects its charging interface with the charging output interface of the vehicle-to-vehicle charging device 13 through the second charging circuit, and stores the received electric energy through the charging output interface of the vehicle-to-vehicle charging device 13.

The vehicle-to-vehicle charging device 13 is an electronic device independent of the energy supply vehicle 11 and the energy supply vehicle 12, in the running process of the system, the vehicle-to-vehicle charging device 13 is connected with the charging interface of the energy supply vehicle 11 and the energy supply vehicle 12 respectively through the first charging circuit and the second charging circuit, and correspondingly converts electric energy received by the charging input interface (namely, electric energy input by the energy supply vehicle 11) through an internal energy conversion module, and outputs the electric energy to the energy supply vehicle 12 through the charging output interface, so that the transfer of the corresponding electric energy between the two vehicles is realized.

The first charging circuit and the second charging circuit may be configured to have corresponding structures and models according to corresponding industry specifications, for example, the charging circuit is composed of charging gun portions at two ends and a transmission line portion in the middle, so that the charging gun portions may be designed to have an integral or separate structure according to user requirements, and line materials and types contained in the transmission line portions may be changed according to specific regulations corresponding to vehicle sales areas, which is not limited in this specification.

Furthermore, the powered vehicle 11 and the vehicle to be powered 12 may be dependent on a charging interface to which a charging line of the respective vehicle is connected in the vehicle-to-vehicle charging device 13. For example, in the case where the first charging line of the powered vehicle 11 is connected to the charging output interface of the vehicle and the second charging line of the powered vehicle 12 is connected to the charging input interface, the powered vehicle 12 will serve as a new powered vehicle to provide electrical energy to charge the original powered vehicle 11 (i.e., the current powered vehicle). Further, the relation between the actual electric quantity of the energy supply vehicle 11 and the actual electric quantity of the vehicle to be charged 12 is not limited in the present specification, so the energy supply vehicle 11 may be a vehicle with an almost-spent electric quantity, and the vehicle to be charged 12 may be a vehicle with a sufficient idle electric quantity, or vice versa.

The external structure of the above-described vehicle-to-vehicle charging apparatus will be described below with reference to fig. 2, and as shown in fig. 2, the housing of the vehicle-to-vehicle charging apparatus 20 is approximately cubic in shape, with a convex structure having a trapezoid shape in the middle portion and both sides of the top. The design of the protruding structure enables the power-on key 201, the touch display 202, the direct-current charging input interface 211, the direct-current charging output interface 212 and the protective cover 213 which are disposed on the surface of the protruding structure to be observed and contacted conveniently by a user when the vehicle-to-vehicle charging device 20 is horizontally placed on a plane such as the ground or a desktop. In addition, the left and right sides of the vehicle-to-vehicle charging apparatus 20 are respectively provided with symmetrical grooves so as to facilitate easy handling of the vehicle-to-vehicle charging apparatus 20 by a user.

The protective cover 213 may be used to isolate the charging input interface and the charging output interface from the outside, so as to prevent the foreign objects from blocking the interfaces and causing poor contact between the charging circuit and the interfaces. Of course, besides the flip cover-like structure shown in fig. 2, the protective cover plate can also be designed into a sliding cover type, an embedded type, a magnetic attraction type and other structures according to practical situations, and the utility model is not limited in this specification.

Besides the external components, the vehicle-to-vehicle charging equipment is internally provided with a signal generation module and an energy conversion module. The signal generating module can be used for generating a charging state (Charger charging state, CCS) signal of the charger carrying a positive current output value, and the CCS signal can be sent to the energy supply vehicle through the charging input interface in a message form; the energy conversion module can be respectively connected with the charging input interface and the charging output interface and can be used for converting the electric energy received by the charging input interface into electric energy suitable for the charging output interface; of course, the signal generating module and the energy converting module may be provided in a circuit inside the vehicle-to-vehicle charging apparatus in the form of separate modules or integrated modules, which is not limited in this specification.

As previously described, unlike the scheme of charging with alternating current at low voltage using bi-directional OBC, the scheme of the present specification provides a more efficient manner of charging.

In an embodiment, the charging input interface and the charging output interface may be hvdc charging interfaces. Specifically, the high-voltage direct current electric energy in the battery pack of the energy supply vehicle can be transmitted to the charging input interface through the first charging circuit and is output to the battery pack of the vehicle to be supplemented through the charging output interface after being converted by the energy conversion module, the electric energy keeps the form of the high-voltage direct current in the whole process, and the condition that the charging efficiency is reduced due to the fact that the electric energy is converted into low-voltage alternating current is avoided.

As described above, different charging modes correspond to different charging interfaces. Specifically, the charging input interface and the charging output interface may be designed with different internal pins according to specific design specifications, and the following explanation is made with reference to fig. 3 on the internal pins of the charging input interface and the charging output interface according to the specification of "communication protocol between non-vehicle-mounted conductive charger and battery management system of electric vehicle" of GB/T27930-2015 (abbreviated as "GB/T27930-2015"):

in an embodiment, the charging input interface and the charging output interface include a DC positive electrode dc+ port and a DC negative electrode DC-port, the energy conversion module is located on a main power supply circuit where the DC positive electrode dc+ port and the DC negative electrode DC-port are located, the main power supply circuit corresponds to a loop formed by two circuits where the DC positive electrode DC-port and the DC positive electrode dc+ in fig. 3 are located, and the main power supply circuit is connected to a battery pack of a powered vehicle, so that high-voltage direct current in the battery pack can be directly transmitted to the vehicle to be supplemented.

The main power supply circuit may be provided with a relay provided at least in the device body of the vehicle-to-vehicle charging device and in the power supply vehicle, and the relay may be kept closed during charging of the power supply vehicle and opened after the charging is completed. Taking relays K5, K6 and K1, K2 on the main power supply circuit in fig. 3 as an example: the front two are positioned in the energy supply vehicle and are respectively used for controlling the communication between the DC+ and the DC-port and the battery pack; the latter two are in the vehicle-to-vehicle charging equipment and are used for controlling the communication between the DC+ and DC-ports and the energy conversion module respectively. Obviously, in the case of simultaneous closing of the relays K5, K6 and K1, K2, the main power supply circuit can perform a complete circuit, thereby controlling the battery pack of the powered vehicle to perform a discharge-like operation. The energy conversion module can be a Buck-Boost (DC/DC) converter, wherein the Buck-Boost design is introduced to ensure that the energy supply vehicle and the vehicle to be supplemented can still realize the transmission of high-voltage direct current electric energy between the energy supply vehicle and the vehicle to be supplemented under the conditions of different types and different charging powers, and the application range of the vehicle-to-vehicle charging equipment is enlarged. Of course, as shown in fig. 3, the configuration and implementation of the components and modules of the above-mentioned main power supply circuit, such as the fuse, the current detection, etc. are basically disclosed in the related art, and therefore, the description thereof will not be repeated in this specification.

In an embodiment, the charging input interface and the charging output interface include a charging communication CAN-hs+ port and a charging communication CAN-LS-port, the signal generating module is located on a communication circuit where the s+ port and the S-port are located, and sends the CCS signal to the powered vehicle through the communication circuit, the communication circuit corresponds to a loop formed by two circuits where the s+ port and the s+ port are located in fig. 3, and the communication circuit is respectively connected to a vehicle controller of the powered vehicle and an equipment control module (assuming that the signal generating module in the embodiment belongs to a sub-module inside the equipment control module), so that the CCS signal generated by the signal generating module CAN be sent to the vehicle controller. According to the functional explanation of the CCS message in fig. 5, the message may be used for the total state of charge of the charger (i.e. the vehicle-to-vehicle charging device in this specification), and in particular, the relevant parameter table of the CCS message is specified in GB/T27930-2015 as follows:

as will be seen below for each of the stages of fig. 4, relays K5, K6 have been closed by default after the powered vehicle has been physically connected to the vehicle-to-vehicle charging device, prior to the charging stage. The parameters of the CCS message may determine whether the relays K5 and K6 of the energy supply vehicle on the main energy supply circuit continue to maintain the closed state, so that the energy supply vehicle charges the vehicle to be supplemented through the vehicle-to-vehicle charging device continuously.

In an embodiment, the signal generating module may further ensure that K5 and K6 are in a closed state by modifying parameters in CCS messages to fool the powered vehicle into a charged state, for example: when the current output value in the CCS message received by the vehicle is negative, the vehicle can determine that the currently connected charging device normally outputs reverse electric energy, so that the vehicle immediately exits from the charging state, and disconnects K5 and K6. Therefore, if the signal generating module takes the absolute value of the current output value to make the energy supply vehicle mistakenly be in the electric quantity of the charging equipment such as the receiving charging pile, the K5 and the K6 are continuously in the closed state so as to ensure the normal operation of the main energy supply circuit.

In an embodiment, the device body of the vehicle-to-vehicle charging device is further provided with a 12V power supply for outputting an auxiliary voltage to wake up the powered vehicle and the vehicle to be supplemented, where wake-up may refer to switching the corresponding vehicle controller from the sleep mode to the operation mode, so as to facilitate successful execution of the charging stage and the like. In this embodiment, the charging input interface and the charging output interface may include a positive a+ port of a low-voltage auxiliary power supply and a negative a-port of a charging communication low-voltage auxiliary power supply, and the 12V power supply is located on an auxiliary power supply circuit where the a+ port and the a-port are located, where the auxiliary power supply circuit corresponds to a circuit formed by two circuits where the a-port and the a+ are located in fig. 3, and the 12V power supply may ensure correct operation of other circuits and devices (such as a touch display screen) of the vehicle-to-vehicle charging device body. Of course, the specific specification of the power supply may be set to different numbers according to different regulations, and this is not limited in this specification.

It will be understood by those skilled in the art that, although the specific circuit between the vehicle-to-vehicle charging device and the vehicle to be supplemented in fig. 3 is not further shown, the specific circuit substantially accords with the circuit design concept disclosed in the conventional charging manner of the "charging stake-vehicle to be supplemented", so that a detailed description thereof will not be given in the present specification, and meanwhile, the connection between the charging output interface of the vehicle-to-vehicle charging device and the vehicle to be supplemented in the following description is correctly completed through the second charging circuit.

The relationship between the states of the relays K5, K6 and the CCS signal is further described below with reference to fig. 4. Fig. 4 is a flow chart of a vehicle-to-vehicle charging apparatus and powered vehicle during a charging process according to an embodiment of the present disclosure. As shown in fig. 4, in the process of transferring electric energy between the vehicle-to-vehicle charging device and the powered vehicle, the following phases may be specifically classified: physical connection, low-voltage auxiliary power-on, charging handshake, charging parameter configuration, formal charging and ending charging. From the charging handshake stage, the functional vehicle and the vehicle-to-vehicle charging equipment perform information interaction through messages, and the messages need to strictly follow corresponding standards, and as the messages related in fig. 4 follow the specification of national standard direct current (GB/T27930-2015), the actions of the messages can be sequentially known according to the table shown in fig. 5, and the actions of the messages are exerted in fig. 4.

3. In the charging handshake phase, the vehicle-to-vehicle charging device sends a handshake message CHM to the energy supply vehicle, and meanwhile, the charging communication protocol version is transmitted to the energy supply vehicle (for example, the version number of the old national standard protocol in 2011 is V1.0, and the version number of the new national standard protocol in 2015 is V1.1), and after the CHM is received, the energy supply vehicle returns a message BHM to provide the highest allowable charging total voltage of the energy supply vehicle. After that, both sides use CRM, BRM and other messages to carry out handshake discrimination.

4. And in the charging parameter configuration stage, the vehicle-to-vehicle charging equipment and the energy supply vehicle exchange related parameters which are required to be involved in the charging process respectively through messages such as BCP, CTS and the like. Simultaneously K1, K2, K5 and K6 are closed to ensure successful operation of the main supply circuit.

5. In the formal charging stage, aiming at the CSS message, the vehicle-to-vehicle charging equipment periodically transmits the CSS message with the current output value modified to the energy supply vehicle, so that the energy supply vehicle can be continuously kept in a charging state.
