Technical Field

Background
With the continuous popularization of new energy vehicles, the current power change of the new energy vehicles can be a way for effectively solving the problem of short endurance mileage of the new energy vehicles when the electric quantity of the new energy vehicles is insufficient. How to reasonably distribute the replaceable electricity resources in the power exchange station is the current research direction. At present, operators of the power exchange station face different use demands, and the power exchange modes of the power exchange station are different. Some power exchange station operators only provide power exchange service for own internal new energy vehicles (the internal new energy vehicles can be divided into main position new energy vehicles and non-main position new energy vehicles), and in order to ensure that the main position new energy vehicles do not delay the normal operation of enterprises, the power exchange station needs to ensure that the internal main position vehicles exchange power preferentially. Some power plant operators may also sometimes exchange power from external new energy vehicles to obtain additional benefits, and a power plant of this mode of operation is called an open power plant. In the operating mode of an open power plant, the exchangeable electrical resources in the power plant are limited. In the limited exchangeable power resources, the operator of the power exchange station needs to ensure that the new energy vehicles of the main stations in the interior work normally, so that an open power exchange station capable of reasonably distributing the resources in the power exchange station is needed to meet the requirement of normal operation in the interior. The operators of the power exchange stations need to solve the problem that the exchangeable power resources in the open power exchange stations can be reasonably distributed.

The embodiment discloses a method for switching power for a new energy vehicle 10, as shown in fig. 1, which may include:
step S11, based on the new energy vehicle 10 entering the power change area, the first acquisition device 25 acquires information stored in the first memory 111 on the power change battery box 11 of the new energy vehicle 10; wherein, the first memory 111 includes identity information of the battery box 11;
step S12, judging whether the battery box 11 is physically compatible with the battery box 20 based on the identity information of the battery box 11;
step S13, based on the physical compatibility of the battery box 11 and the battery box 20, the battery box 11 is in signal communication with the new energy vehicle 10 through the identity information of the battery box 11 and the new energy vehicle 10 is acquired by the battery box 30;
in step S14, the power exchanging station 20 guides the new energy vehicle 10 to stop the vehicle based on the identity information of the new energy vehicle 10 as the priority power exchanging vehicle.
In this embodiment, an open type power exchanging method is proposed for the power exchanging station 20 of the power exchanging station operator to enable the power exchanging station 20 to exchange power with the new energy vehicle 10 inside the power exchanging station operator in different states, and to exchange power with the new energy vehicle 10 outside the power exchanging station operator. The new energy vehicles 10 in the power exchange station operators can be divided into main-position new energy vehicles 10 and non-main-position new energy vehicles 10 according to positions, the main-position new energy vehicles 10 cannot timely exchange electricity, large losses are caused to the internal operation of the power exchange station operators, the non-main-position new energy vehicles 10 do not timely exchange electricity, and the losses caused to the internal operation of the power exchange station operators are small, so that the open power exchange station 20 can preferably meet the electricity exchange requirements of the main-position new energy vehicles 10 in different states, and the non-main-position new energy vehicles 10 can not timely meet the electricity exchange requests. In order to make additional gains available to the enterprise, it is sometimes also possible to replace the new energy vehicle 10 outside the operator of the station, so that the utilization of the station 20 can be maximized. As shown in fig. 1, a method for switching power from the new energy vehicle 10 to the power source may include steps S11 to S14, and the steps S11 to S14 will be described in detail below.
In step S11, the battery box 11 of the new energy vehicle 10 may have a readable first storage portion thereon, and the first memory 111 may be provided on the battery box 11 for storing information of the battery box 11. A first collecting device 25 may be arranged in the open exchange station 20. The first acquisition device 25 may be disposed in a power exchanging area of the power exchanging station 20, and the first acquisition device 25 may be configured to acquire identity information of the power exchanging cell box 11 in the first memory 111. When the new energy vehicle 10 needing to change electricity enters the electricity changing area of the electricity changing station 20 (the electricity changing area refers to the area through which the new energy vehicle 10 needs to pass when going to the specified parking position of the electricity changing station 20), the first collecting device 25 can obtain the identity information of the electricity changing battery box 11 by communicating with the first memory 111 on the electricity changing battery box 11 of the new energy vehicle 10. In other embodiments, the information in the first memory 111 may be obtained by using Radio Frequency Identification (RFID) technology (RFID is a non-contact automatic identification technology and may be used to quickly and automatically identify the electronic tag content corresponding to the target object). The first storage device may be an electronic tag, and may store identity information of the battery box. The first collecting device 25 may be a reader, and may read an electronic tag, so that identity information of the battery box 11 may be conveniently and quickly obtained.
In step S12, based on the identity information of the battery box 11 acquired by the first acquisition device 25, the first acquisition device 25 may transmit the identity information of the battery box 11 to the battery box 20, and the battery box 20 may compare and determine the identity information on the battery box, to determine whether the battery box 11 is physically compatible with the battery box 20 (physical compatibility means that the charging device of the battery box 20 may be matched with the size, the charging connector, the coolant connector, etc. of the battery box 11). Only the above conditions are satisfied, and it is possible to obtain that the battery box 11 for the power exchange on the new energy vehicle 10 is a battery box in which the power exchange station 20 can be replaced.
In step S13, after the power exchange station 20 determines that the power exchange battery box 11 can meet the replaceable standard of the power exchange station 20, the power exchange station 20 may upload the identity information of the power exchange battery box 11 to the power exchange cloud platform 30. If the new energy vehicle 10 does not reach the parking power exchanging position in the power exchanging station 20 and the new energy vehicle 10 does not stop and stall, the new energy vehicle 10 is connected with the power exchanging station 20, and the new energy vehicle 10 may release the locking mechanism 112 in advance, so that the power exchanging battery box 11 falls and a safety accident is caused. In order to ensure the safety of the power change operation, the power change cloud platform 30 first determines that the new energy vehicle 10 is a priority power change vehicle; then, the new energy vehicle 10 reaches a parking power change position in the power change station 20, and after the new energy vehicle 10 is parked and extinguished, the new energy vehicle 10 and the power change station 20 can be in signal communication. The judgment result of the power conversion cloud platform 30 on the new energy vehicle 10 is used as a primary condition, so that the situation that the power conversion battery box 11 is not accidentally dropped when the new energy vehicle 10 is subjected to power conversion at the power conversion station 20 is ensured, and the safety of vehicle power conversion is ensured. The power conversion cloud platform 30 can be a terminal server, can be connected with the new energy vehicle 10 in real time to acquire the identity information of the new energy vehicle 10, can store the new energy vehicle 10 information meeting the power conversion condition, and can analyze and screen out the identity information of the prior power conversion new energy vehicle 10 and the identity information of the common power conversion new energy vehicle 10; the result of the analysis is then transferred to the power exchange station 20, from which the power exchange station 20 can perform the next operation.
In step S14, when the resources of the replaceable battery box in the open type power exchanging station 20 are strained, the open type power exchanging station 20 may ensure that the priority power exchanging new energy vehicle 10 may be exchanged to a battery. Based on the power conversion cloud platform 30 acquiring the identity information of the target new energy vehicle 10, the power conversion cloud platform 30 can analyze and screen whether the new energy vehicle 10 is a priority power conversion vehicle. When the target new energy vehicle 10 is a preferential power exchange vehicle of the power exchange station 20, after the power exchange cloud platform 30 transmits data to the power exchange station 20, the power exchange station 20 can guide the target new energy vehicle 10 to a positioning parking position of the new energy vehicle 10 so as to perform a next power exchange operation on the target new energy vehicle 10 in the power exchange station 20, so that the problem that the preferential power exchange vehicle is subjected to preferential power exchange in the open power exchange station 20 can be solved.
In some embodiments, as shown in fig. 2, the new energy vehicle 10 open power conversion method further includes:
in step S141, based on the identity information of the new energy vehicle 10 being the ordinary power exchange vehicle and the power exchange station 20 being in the busy state, the power exchange station 20 sends out the refusal power exchange information.
In this embodiment, as shown in fig. 2, when the power exchange station 20 transmits the information of the first memory 111 to the power exchange cloud platform 30, the power exchange cloud platform 30 analyzes and screens the vehicle as a common power exchange vehicle based on the battery box identity information stored in the first memory, and the open power exchange station 20 is in a busy state, the replaceable battery box resources in the power exchange station 20 are tense, and the power exchange requirement of the common power exchange vehicle cannot be met, so the power exchange station 20 can reject the power exchange request of the common power exchange vehicle. In other embodiments, the priority battery-powered vehicle may be a battery-powered vehicle at a primary station, or may be a battery-powered vehicle when the battery level of the vehicle is below a certain threshold. The ordinary electric vehicle may be a non-primary electric vehicle or an external new energy vehicle 10. In other embodiments, the rejection may be an audible alert to the ordinary battery exchange vehicle in the battery exchange area and blocking it from further entering the battery exchange station 20. The station may guide the ordinary vehicle away from the station 20 and assist the ordinary vehicle in finding the next station 20 where power may be replaced. In this way, when the power exchange station 20 is in a busy state, the priority power exchange vehicle can be ensured to have a replaceable battery box, so that the battery box resources of the power exchange station 20 are reasonably distributed.
In some embodiments, as shown in fig. 2, the new energy vehicle 10 open power conversion method further includes:
in step S142, the power exchange station 20 guides the new energy vehicle 10 to stop in a fixed position based on the identity information of the new energy vehicle 10 being the normal power exchange vehicle and the power exchange station 20 being in the idle state.
In this embodiment, as shown in fig. 2, the power exchange station 20 collects information of the first memory 111 and transmits the information to the power exchange cloud platform 30. The battery box information stored in the first storage part is analyzed and screened by the battery-changing cloud platform 30 to obtain a common battery-changing vehicle, and the open battery-changing station 20 is in an idle state, so that the battery-changing requirement of the common battery-changing vehicle can be met. In other embodiments, a conventional battery-powered vehicle may be a battery-powered vehicle that is not a primary station or an external new energy vehicle 10. The battery exchange station 20 performs the next operation on the ordinary battery exchange vehicle, and guides the ordinary battery exchange vehicle to enter the battery exchange station 20 to locate the parking position and wait for battery exchange. In this way, the resources of the replaceable battery box in the power exchange station 20 can be reasonably distributed, so that the utilization rate of the power exchange station 20 can be maximized.
In some embodiments, as shown in fig. 2, the new energy vehicle 10 open power conversion method further includes:
step S151, based on the new energy vehicle 10 being positioned and being parked and flameout, the vehicle-mounted control system 12 sends out a power conversion request signal;
in step S152, based on the identity information of the new energy vehicle 10 in the power conversion request signal and the identity information of the new energy vehicle 10 provided by the power conversion cloud platform 30 being the same, the power conversion control system 21 is in signal communication with the vehicle-mounted control system 12.
In the present embodiment, the new energy vehicle 10 may further include an in-vehicle control system 12. The in-vehicle control system 12 may include a second memory 121. The second memory 121 is in signal communication with the onboard control system 12, and the second memory 121 may be used to store identification information of the vehicle. The in-vehicle control system 12 may read the vehicle identification information in the second memory 121, or may write the vehicle identification information into the second memory 121. As shown in fig. 2, in step S151, when the new energy vehicle 10 can enter the open type power exchange station 20, the vehicle can reach a locating point by being guided by the locating device through the guiding route of the power exchange station 20 to a specified parking position within the power exchange station 20; the new energy vehicle 10 is then shut down and extinguished. Based on the new energy vehicle 10 stopping and extinguishing, the vehicle-mounted control system 12 in the new energy vehicle 10 can send out a power change request signal with the identity information of the target power change new energy vehicle 10, so that the next power change operation is facilitated.
In step S152, based on the fact that the identity information of the new energy vehicle sent by the power conversion cloud platform 30 and the identity information of the new energy vehicle 10 sent by the vehicle-mounted control system 12 are received by the power conversion station 20, the power conversion control system 21 in the power conversion station 20 can be in signal communication with the vehicle-mounted control system 12 of the new energy vehicle 10 in the power conversion station 20. Based on the signal communication between the power exchange station 20 and the new energy vehicle 10, the new energy vehicle 10 and the power exchange station 20 can be mutually matched to complete power exchange.
In some embodiments, as shown in fig. 2, the new energy vehicle 10 open power conversion method further includes:
step S161, based on the signal communication between the power-change control system 21 and the vehicle-mounted control system 12, the power-change control system 21 controls the power-change robot 23 to grasp the power-change battery box 11;
step S162, based on the battery-changing robot 23 grasping the battery-changing box 11, the vehicle-mounted control system 12 controls the locking mechanism 112 of the battery-changing box 11 to release;
step S163, releasing the battery box 11 based on the locking mechanism 112, and the battery box 11 is transported to the charging bin 22 of the battery exchange station 20 by the battery exchange robot 23;
in step S164, the battery-charging box 11 is placed in the charging bin 22 based on the battery-charging robot 23, and the battery-charging box 24 in the charging bin 22 is transported to the new energy vehicle 10 by the battery-charging robot 23.
In the present embodiment, the battery exchange station 20 may further include a charging bin 22, a battery exchange robot 23, and a battery exchange control system 21. The power-change control system 21 may communicate with the on-board control system 12 of the new energy vehicle 10 within the power-change station 20, and the power-change control system 21 may also send operation instructions to the power-change robot 23. The battery changing robot 23 can grasp the battery changing box 11 on the new energy vehicle 10 and move to the battery charging bin 22, and can grasp the battery charging box 24 with the electric quantity meeting a certain threshold in the battery charging bin 22 to be installed in the new energy vehicle 10.
