As shown in fig. 1, the charging and battery exchange station integrated system includes a charging station subsystem 110 and a battery exchange station subsystem 120, wherein the charging station subsystem 110 includes a power management unit 111 and a plurality of first charging units 112, and the battery exchange station subsystem 120 includes an energy management unit 121 and a plurality of second charging units 122. The power management unit 111 is configured to obtain charging demand information of the vehicle and a maximum output power of the first charging unit 112, and send a charging cut-in request to the energy management unit 121 when it is determined that the first charging unit 112 does not meet a charging demand of the vehicle according to the charging demand information and the maximum output power of the first charging unit 112. The energy management unit 121 is configured to control the at least one second charging unit 122 to cut into the charging station subsystem 110 when receiving the charging cut-in request, so that the first charging unit 112 and the at least one second charging unit 122 together charge the vehicle.

Thereby, the charging demand information of the vehicle and the maximum output power of the first charging unit 112 are obtained through the power management unit 111, and when it is determined that the first charging unit 112 does not meet the charging demand of the vehicle according to the charging demand information and the maximum output power of the first charging unit 112, a charging cut-in request is issued to the energy management unit 121; when receiving the charging cut-in request, the energy management unit 121 controls the at least one second charging unit 122 to cut into the charging station subsystem 110, so that the first charging unit 112 and the at least one second charging unit 122 jointly charge the vehicle, and therefore, by sharing the second charging unit 122, not only the output power requirements of the charging station and the power exchange station can be met, but also the station construction cost can be reduced, and the utilization rate of electric power resources can be improved.

For convenience of understanding, the structure of the integrated system of the charging and exchanging station according to the embodiment of the invention will be specifically described.

The charging station subsystem 110 is used for directly charging the vehicle, and the charging station subsystem 110 comprises a power management unit 111 (Power Management System, PMS) and a plurality of first charging units 112, which in this embodiment may be ACDC power sources.

The power management unit 111 may be respectively configured to communicate with all the first charging units 112, and the power management unit 111 may communicate with the first charging units 112 in the following manner: communication is realized through an RS-485 interface, a CAN interface and the like, and the communication is not particularly limited herein. When it is necessary to charge the vehicle, the power management unit 111 may control the output power of the first charging unit 112 through communication; when the first charging unit 112 starts to charge the vehicle, the first charging unit 112 may report charging information to the power management unit 111 through communication, for example, the first charging unit 112 reports information such as actual output power to the power management unit 111.

The power management unit 111 may also be in communication with the energy management unit 121 of the power exchange station subsystem 120, and the power management unit 111 may also communicate with the energy management unit 121 in the following manner: communication is realized through an RS-485 interface, an Ethernet, a CAN interface and the like. The power management unit 111 is scheduled by the energy management unit 121; in addition, when the maximum output power of the first charging unit 112 does not satisfy the charging demand of the vehicle, the power management unit 111 may upload information such as the charging demand of the vehicle and the maximum output power of the first charging unit 112 to the energy management unit 121.

The first charging unit 112 is connected to the charging gun 114 through two wires, and can charge the vehicle through the charging gun 114. In addition, a first relay, i.e., K11, K12 in fig. 1, is provided on both wires between the first charging unit 112 and the charging gun 114. The power management unit 111 may control whether the first charging unit 112 outputs electric power to the charging gun 114 by controlling the closing or opening of the first relay. In this embodiment, the charging station subsystem 110 includes a plurality of first charging units 112, and correspondingly includes a plurality of charging guns 114, and the connection modes of each first charging unit 112 and the charging gun 114 are the same, which will not be described in detail herein.

In addition, in general, the charging power requirements of each charging terminal of the charging station are large; the number of battery packs in the power exchange station is large, and in the operation process, the number of battery packs full of electricity in each time period is only required to be guaranteed, so that the charging power requirement of each battery pack in the power exchange station is small. In the present embodiment, the maximum output power of the first charging unit 112 may be determined according to the charging power demand of the charging terminal; the maximum output power of the second charging unit 122 is determined according to the charging power demand of the battery pack.

In some embodiments, charging station subsystem 110 further includes a charging control unit 113 (Fast Charge Control Unit, FCU), charging control unit 113 being configured to establish communication with charging cloud platform 115 to obtain charging demand information from charging cloud platform 115 and send it to power management unit 111.

Specifically, the charging control unit 113 establishes communication connection with the vehicle to be charged, the power control unit, and the charging cloud platform 115. The charging control unit 113 CAN establish communication connection with the vehicle through a CAN interface, and performs information interaction with the vehicle according to GBT 27930. The charging control unit 113 may establish a communication connection with the charging cloud platform 115 through the internet, and the charging control unit 113 may obtain vehicle information of the vehicle to be charged from the charging cloud platform 115, where the vehicle information includes (but is not limited to): charging demand information of the vehicle, vehicle identification information, and the like; the charge control unit 113 may also transmit charge fee information to the charge cloud platform 115 in order to settle charge fee for the user. It should be noted that the charging demand information of the vehicle may be a charging power required by the vehicle. The charging control unit 113 CAN establish communication connection with the power control unit through an RS-485 interface, a CAN interface and the like, and the charging control unit 113 uploads the obtained vehicle information to the power control unit through the communication mode.

The battery replacement station subsystem 120 is used to replace the vehicle and to charge the battery pack for replacement. The battery exchange subsystem 120 includes an energy management unit 121 (Battery Management System, BMS) and a plurality of second charging units 122, which in this embodiment may also be ACDC power sources. In some embodiments, the battery plant subsystem 120 further includes a plurality of battery plant charge control units 123 (Exchange Baterry Charge Unit, EBCU).

Specifically, the energy management unit 121 establishes a communication connection with each of the battery charging control units 123, and the communication manner may be: and communication is performed through an RS-485 interface, a CAN interface and the like. Each battery-charging control unit 123 of the battery-charging station also establishes a communication connection with a second charging unit 122, and the communication manner may be as follows: and communication is performed through an RS-485 interface, a CAN interface and the like. The energy management unit 121 controls the charging process of each second charging unit 122 through the battery-exchange-station-charging control unit 123.

Each battery-charging control unit 123 of the battery-charging station may also establish communication with a corresponding battery pack, and the communication manner may be: and communication is performed through a CAN interface and the like. The battery charging control unit 123 may acquire information of the remaining electric power value SOC, the battery health SOH, and the like of the battery pack through communication.

The second charging unit 122 is connected to the battery pack to be charged through two wires, and the two wires are respectively provided with a second relay (e.g. K21, K22 in fig. 1). The battery-charging control unit 123 may control whether the second charging unit 122 outputs electric power to the battery pack by controlling the closing or opening of the second relay.

It should be noted that, in the present embodiment, before the first relay, a first node is disposed on two wires connected between the first charging unit 112 and the charging gun 114; likewise, before the second relay, a second node is provided on both wires connecting between the second charging unit 122 and the battery pack to be charged. The first node and the second node are also connected through two wires, and a third relay (such as K31 and K32 in fig. 1) is arranged on the wires. The battery-charging control unit 123 may also control the second charging unit 122 to output electric energy to the vehicle by controlling the second relay to open and the third relay to close.

Thus, it can be seen that the second charging unit 122 in this embodiment can not only charge the battery pack in the battery exchange station, but also cut into the charging station subsystem 110 to charge the vehicle when the maximum output power of the first charging unit 112 does not meet the charging requirement of the vehicle. Therefore, the charging power of the charging station can be greatly improved without additionally adding the first charging unit 112, the station building cost is reduced, and the utilization rate of electric power resources is improved.

The working process of each unit is specifically described below with reference to the structure of the integrated system of the charging and replacing station.

When the charging station subsystem 110 charges the vehicle to be charged, the charging control unit 113 obtains charging requirement information of the vehicle from the charging and platform, and uploads the charging requirement information to the power management unit, where the charging requirement information may be charging power required by the vehicle. The power management unit 111 also obtains the maximum output power of the first charging unit 112, and determines whether the maximum output power of the first charging unit 112 meets the charging power required by the vehicle by comparing the maximum output power of the first charging unit 112 with the charging requirement information of the vehicle. If so, the power management unit 111 directly controls the first relay to be closed, so that the first charging unit 112 charges the vehicle. If not, the power management unit 111 reports the maximum output power of the first charging unit 112 and the charging requirement information of the vehicle to the energy management unit 121, and sends a charging cut-in request to the energy management unit 121. After receiving the charging cut-in request, the energy management unit 121 controls the at least one second charging unit 122 to cut into the charging station subsystem 110, so that the first charging unit 112 and the at least one second charging unit 122 together charge the vehicle.

In some embodiments, the energy management unit 121 is specifically configured to: acquiring the total number of the first charging units 112, the total number of the second charging units 122, the maximum output power of the second charging units 122, and charging information of each second charging unit 122; determining a cut-in number of the second charging unit 122 according to the total number of the first charging units 112, the total number of the second charging units 122, the maximum output power of the first charging units 112, and the maximum output power of the second charging units 122; the second charging units 122 to be cut in are determined according to the charging information and the cutting-in number of the second charging units 122, and the second charging units 122 to be cut in are controlled to be cut into the charging station subsystem 110.

Specifically, after receiving the charging cut-in request, the energy management unit 121 first obtains the total number of the first charging units 112, the total number of the second charging units 122, the maximum output power of the second charging units 122, and the charging information of each second charging unit 122. It should be noted that the total number of the first charging units 112 and the total number of the second charging units 122 may be input to the energy management unit 121 in advance by a worker according to the actual number. Similarly, after determining the maximum output power of the first charging unit 112 and the maximum output power of the second charging unit 122, these two parameters may be input to the energy management unit 121 in advance. The charging information of the second charging unit 122 may be reported to the energy management unit 121 by the second charging unit 122, and it should be noted that the charging information may be a required charging amount of the battery pack.

After the energy management unit 121 obtains the total number of the first charging units 112, the total number of the second charging units 122, the maximum output power of the second charging units 122, and the charging information of each second charging unit 122, the energy management unit 121 determines the cut-in number of the second charging units 122 according to the total number of the first charging units 112, the total number of the second charging units 122, the maximum output power of the first charging units 112, and the maximum output power of the second charging units 122. In some embodiments, the number of cuts may be determined by:

where n is the number of cuts in, a is the total number of second charging units 122, b is the total number of first charging units 112, X is the maximum output power of the second charging units 122, and Y is the maximum output power of the first charging units 112.

After determining the number of cuts, the energy management unit 121 determines the second charging unit 122 to be cut according to the number of cuts and the charging information of the second charging unit 122. Here, it should be noted that the second charging units 122 to be cut into are the second charging units 122 that need to be cut into the charging station subsystem 110 in all the second charging units 122.

In this embodiment, the energy management unit 121 may operate in two modes, one being a charging station priority mode and the other being a battery exchange station priority mode, and the operator may select one of the two modes to operate the energy management unit 121.

In some embodiments, if the energy management unit 121 is operated in the charging station priority mode, the energy management unit 121 is further specifically configured to: ordering the second charging units 122 according to the required charge amounts of the respective second charging units 122; and selecting the second charging unit 122 with the cutting-in number from the position with the minimum required charging amount, and taking the second charging unit 122 as the second charging unit 122 to be cut in. Specifically, the energy management unit 121 may sort the second charging units 122 in order of the required charge amount from small to large, and select from the second charging units 122 having the smallest required charge amount until the second charging units 122 having the number of cuts are selected, and use these second charging units 122 as the second charging units 122 to be cut.

In some embodiments, if the energy management unit 121 is operating in the power-plant priority mode, the energy management unit 121 is further specifically configured to: the second charging units 122 with the required charging amount of zero are selected from all the second charging units 122, and the second charging units 122 are used as the second charging units 122 to be cut in. Specifically, in the battery-replacement-station priority mode, the energy management unit 121 selects only the second charging unit 122 whose required charge amount is zero as the second charging unit 122 to be cut in; if none of the demanded charge amounts of the second charging unit 122 is zero, the second charging unit 122 is no longer cut into the charging station subsystem 110.

After determining that the second charging unit 122 is to be cut in one of the two ways, the energy management unit 121 will first issue a charging stopping instruction to the charging control unit 123 of the power exchange station corresponding to the second charging unit 122 to be cut in. The battery-charging control unit 123 of the battery-charging station controls the corresponding second charging unit 122 to be cut into to reduce the charging power to zero; after the battery charging control unit 123 detects that the output power to be cut into the second charging unit 122 is zero, the battery charging control unit 123 controls the corresponding second relay to be opened and controls the third relay to be closed, thereby completing the cutting operation of the second charging unit 122 to be cut into.

After the second charging unit 122 and the first charging unit 112 are cut into, the energy management unit 121 will send a charging stopping instruction to the power management unit 111; the power management unit 111 further controls the second charging unit 122 to be switched in and the first charging unit 112 to stop power output. When the power management unit 111 detects that the output power of the first charging unit 112 is zero, and the battery charging control unit 123 detects that the output power to be cut into the second charging unit 122 is zero, the battery charging control unit 123 controls the third relay to open. When the charging control unit 123 of the power exchange station receives the charging instruction sent by the energy management unit 121, the charging control unit 123 of the power exchange station controls the second relay to be closed again, so that the second charging unit 122 to be cut in charges the battery pack again, and the second charging unit 122 to be cut in switches back to the power exchange station subsystem 120.

Therefore, when the maximum output power of the first charging unit 112 does not meet the charging requirement of the vehicle, the second charging unit 122 is controlled to cut into the charging station subsystem 110 to charge the vehicle, so that the overtime of charging of the vehicle is not caused, and the user experience is improved; and the energy management unit 121 is used for allocating power, so that the overall economic benefit of the integrated system of the charging and replacing station is guaranteed to be optimal. In addition, the second charging unit 122 is shared by the battery replacement subsystem 120 and the charging station subsystem 110, so that the charging unit can be reduced in building a station, the building cost is reduced, and the utilization rate of electric power resources is improved.

Fig. 2 is a flowchart of a control method of the integrated system of the charging and exchanging station according to the first embodiment of the present invention. The control method is applied to the energy management unit, as shown in fig. 2, and comprises the following steps:

step S210: when a charging cut-in request is received, at least one second charging unit in the battery exchange station subsystem is controlled to cut in the charging station subsystem, so that the first charging unit and the at least one second charging unit in the charging station subsystem jointly charge the vehicle.

The charging cut-in request is sent out by a charging management unit of the charging station subsystem when the first charging unit does not meet the charging requirement of the vehicle.

Therefore, when the charging cut-in request is received, at least one second charging unit in the power exchange station subsystem is controlled to cut in the charging station subsystem, so that the first charging unit and the at least one second charging unit in the charging station subsystem charge the vehicle together, and therefore, the output power requirements of the charging station and the power exchange station can be met, the station building cost can be reduced, and the utilization rate of electric power resources is improved through sharing the second charging unit.

Fig. 3 is a flowchart of a control method of the integrated system of the charging and exchanging station according to the second embodiment of the present invention. In some embodiments, step S210 includes the steps of:

step S310: the total number of the first charging units, the total number of the second charging units, the maximum output power of the second charging units, and charging information of each second charging unit are acquired.

Step S320: the number of cuts in the second charging unit is determined according to the total number of the first charging units, the total number of the second charging units, the maximum output power of the first charging units and the maximum output power of the second charging units.

Step S330: and determining the second charging units to be cut in according to the charging information and the cutting-in number of each second charging unit, and controlling the second charging units to be cut in the charging station subsystem.
