Description
Technical Field
The invention relates to the technical field of electric vehicle power exchange stations, in particular to a power exchange station control method and a power exchange station.
Background
Currently, electric vehicles mainly have two energy supply modes of whole vehicle charging and battery replacement. In the whole vehicle charging mode, the alternating current slow charging leads to long charging time and is limited by a parking lot, and the direct current fast charging shortens the charging time through high power, but has larger impact on a power grid, and meanwhile, the service life of a battery is also reduced. In the battery replacement mode, the battery replacement station can realize orderly charging through interaction with a power grid, and the comprehensive utilization efficiency of the power equipment is improved, so that the electric vehicle can be rapidly supplied with energy, the waiting time of a user is reduced, and the service life of the battery is not reduced. Therefore, the battery replacement mode has high popularization value and economic significance in public transportation watershed of city in China.
However, as the battery is used for an increasingly longer period of time, and the battery case is electrically connected to the charging base, the likelihood of short circuits during charging increases. When a short circuit occurs, the temperature of the battery continues to rise, thereby causing a disaster and even causing explosion of the charging station. The current power exchange station is on duty, after the battery thermal runaway occurs, abnormal batteries are conveyed to the outside of the station for isolation through on-site operation and maintenance personnel, and if dangerous situations occur in the station, dangerous situations are eliminated manually. This approach does not allow for effective risk handling for unattended power stations.

The embodiment discloses a power exchange station control method, as shown in fig. 1, which may include:
step S11, collecting temperature values of a plurality of first temperature probes 31; wherein, the plurality of first temperature probes 31 are arranged on the periphery side of the electric connector 211 of the plurality of charging bases 21;
step S12, based on the temperature measured by the first temperature probe 31 being greater than the first temperature threshold, the first accumulated time starts to be counted;
step S13, based on the temperature measured by the first temperature probe 31 being greater than the first temperature threshold and the first accumulated time being greater than the first time threshold, the power conversion robot 50 moves toward the charging base 21 position corresponding to the first temperature probe 31;
in step S14, the aerosol safety device 30 is triggered to cool down based on the temperature measured by the first temperature probe 31 being greater than the second temperature threshold and the first accumulated time being greater than the second time threshold.
In this embodiment, as shown in fig. 3, 4, 5, 6 and 7, the power exchanging station may include a charging bin 20, a power exchanging bin 10, a battery box 40, a power exchanging robot 50, a first temperature probe 31, and an aerosol safety device 30. When the battery box 40 needs to be replaced, the battery replacement vehicle can be driven into the battery replacement bin 10. The battery box 40 on the battery-changing vehicle can be carried into the charging bin 20 by the battery-changing robot 50 and placed on the idle charging base 21 for charging, and then the fully charged battery box 40 can be carried from the charging bin 20 to the battery-changing vehicle, so that the whole battery-changing process is completed. A plurality of charging bases 21 may be provided in the charging bin 20. Each of the charging bases 21 can charge the battery box 40. The charging base 21 may include an electrical connector 211, and the battery box 40 is electrically connected to the charging base 21 through the electrical connector 211 to be charged. A first temperature probe 31 and an aerosol safety device 30 may be provided on the peripheral side of each electrical connector 211. Since the battery box 40 may generate heat due to poor contact during the electrical connection process with the electrical connector 211, the potential safety hazard existing during the charging process of the battery box 40 may be reduced by the power exchange station control method of the present embodiment, and the power exchange station control method may include steps S11 to S14, as shown in fig. 1, and the following details of steps S11 to S14 will be described below:
in step S11, the temperature values of the first temperature probes 31 disposed on the peripheral sides of the electrical connectors 211 of the plurality of charging bases 21 in the charging bin 20 may be collected. The temperature condition of the peripheral side of the electric connector 211 can be judged through the collected temperature values, so that whether potential safety hazards exist on the peripheral side of the electric connector 211 or not is judged. In other embodiments, one charging base 21 may include a plurality of electrical connectors 211 (the charging base 21 shown in fig. 6 includes 4 electrical connectors 211), and the first temperature probe 31 may be disposed at a peripheral side of each electrical connector 211. By collecting the temperature values of the plurality of first temperature probes 31, the temperature of the charging base 21 during operation can be more accurately judged, and whether potential safety hazards exist can be accurately judged.
In step S12, when the temperature measured by the first temperature probe 31 is greater than the first temperature threshold, the timer may start recording time, and the recording time may be defined as the first accumulated time. During the first cumulative time record, the temperature measured by the first temperature probe 31 may be greater than the first temperature threshold. Since the temperature value at the peripheral side of the electric connector 211 is kept at a higher temperature, it can be determined that a certain potential safety hazard exists at the electric connector 211. Thus, the power exchange station can be conveniently used for implementing measures for avoiding hidden danger.
In step S13, when the temperature measured by the first temperature probe 31 is greater than the first temperature threshold and the first accumulated time is greater than the first time threshold, it may be determined that a certain potential safety hazard exists at the electrical connector 211. The change robot 50 may be controlled to move toward the charging base 21 position where the first temperature probe 31 measures a higher temperature for a certain time. By moving the motor changing robot 50 to the vicinity of the charging base 21 with potential safety hazards in advance, the motor changing robot 50 can rapidly separate the battery box 40 from the charging base 21 when a safety accident is about to occur or the safety accident occurs, so that the time for rescue at the time of the safety accident can be shortened.
In step S14, the first accumulated time may be re-counted when the temperature measured by the first temperature probe 31 continues to rise and is greater than the second temperature threshold. When the measured value of the first temperature probe 31 is high temperature (i.e. greater than the second temperature threshold value) and the duration (i.e. the first accumulated time) is greater than the second time threshold value, the aerosol safety device 30 can be triggered to cool the charging base 21, so as to avoid the occurrence of the safety accident or slow down the further expansion of the safety accident. In other embodiments, multiple aerosol security devices 30 may be provided at different locations on one charging base 21. When the measured value of the first temperature probe 31 is high temperature (i.e. greater than the second temperature threshold) and the duration is greater than the second time threshold, the aerosol safety devices 30 can be triggered simultaneously, so that safety accidents can be avoided better.
In some embodiments, as shown in fig. 2, the power plant control method further comprises:
in step S15, based on the triggering of the aerosol safety device 30, the battery box 40 on the charging base 21 is grabbed by the power conversion robot 50 to move to the waiting area 22.
In this embodiment, as shown in fig. 2, the power exchange station control method may further include step S15. When the aerosol safety device 30 is triggered, it is indicated that the electric connector 211 of the charging base 21 is kept at a high temperature (for example, the temperature is kept above 170 ℃) for a long period of time, so that the battery box 40 on the charging base 21 can be controlled to be moved to the to-be-determined area 22 in the power exchange station by the power exchange robot 50, the battery box 40 and the electric connector of the charging base 21 can be separated, the risk of further expanding the safety accident is reduced, and the potential safety hazard to the battery box 40 on the periphery side of the charging base 21 can be avoided.
In some embodiments, as shown in fig. 2, the power plant control method further comprises:
step S131, based on the temperature measured by the first temperature probe 31 being greater than the second temperature threshold, the gripper of the battery changing robot 50 grips the battery box 40 on the charging base 21; wherein, charging base 21 is provided corresponding to first temperature probe 31.
In this embodiment, as shown in fig. 2, the power exchange station control method may further include step S131. When the temperature measured by the first temperature probe 31 continues to rise and is greater than the second temperature threshold, the gripper of the battery compartment 50 of the battery charging base 21 corresponding to the first temperature probe 31 may grip the battery compartment 40. In this way, when a safety accident is about to occur or has occurred at the electric connection position of the charging base 21 and the battery box 40, the battery box 40 can be quickly lifted by the motor replacing robot 50, so that the battery box 40 and the charging base 21 are quickly separated, thereby avoiding the occurrence of the safety accident or slowing down the further expansion of the safety accident.
In some embodiments, as shown in fig. 2, the power plant control method includes:
step S141, based on the temperature measured by the first temperature probe 31 being greater than the second temperature threshold and the first accumulated time being greater than the second time threshold, the battery box 40 on the charging base 21 is lifted by the power conversion robot 50; wherein, charging base 21 is provided corresponding to first temperature probe 31.
In this embodiment, as shown in fig. 2, the power exchange station control method may include step S141. When the measured value of the first temperature probe 31 is high temperature (i.e. greater than the second temperature threshold value) and the duration time of the measured value is greater than the second time threshold value, it is indicated that the safety accident or the safety accident has occurred at the electric connection position between the charging base 21 and the battery box 40, and the battery box 40 which has been grasped can be quickly lifted by the power conversion robot 50, so that the battery box 40 and the charging base 21 are separated, thereby avoiding the occurrence of the safety accident or slowing down the safety accident to further expand.
In some embodiments, as shown in fig. 2, the power plant control method may further include:
step S132, controlling the electric connection and disconnection of the electric connector on the charging base based on the fact that the temperature measured by the first temperature probe is greater than a second temperature threshold; wherein, the charging base corresponds the setting with first temperature probe.
In this embodiment, as shown in fig. 2, the power exchange station control method may include step S132. When the measured value of the first temperature probe 31 is high (i.e. greater than the second temperature threshold), the electrical connection of the electrical connector 211 disposed on the charging base 21 corresponding to the first temperature probe 31 can be controlled to be disconnected, so as to avoid short circuit.
In some embodiments, as shown in fig. 2, the power plant control method may further include:
step S161, collecting a temperature value of the second temperature probe 32; wherein the second temperature probe 32 is disposed on the peripheral side of the electric connector 211 of the charging base 21 corresponding to the first temperature probe 31; the distance between the second temperature probe 32 and the electric connector 211 of the charging base 21 is greater than the distance between the first temperature probe 31 and the electric connector 211 of the charging base 21;
step S162, based on the temperature measured by the second temperature probe 32 being greater than the third temperature threshold, the second accumulated time begins to be counted;
in step S163, the charging base 21 adjacent to the charging base 21 is controlled to be disconnected from the battery box 40 based on the temperature measured by the second temperature probe 32 being greater than the third temperature threshold and the second accumulated time being greater than the third time threshold.
In this embodiment, as shown in fig. 2, the power exchange station control method may further include steps S161 to S163. A second temperature probe 32 may be further provided on the peripheral side of the electric connector 211 of the charging base 21. The first temperature probe 31 provided at the electrical connector 211 of the same charging base 21 is closer to the electrical connector 211 of the charging base 21 than the second temperature probe 32. The temperature measured by the first temperature probe 31 may be greater than the temperature measured by the second temperature probe 32 during the charging process in which the battery box 40 is placed on the charging base 21. In step S161, the temperature value measured by the second temperature probe 32 may be acquired. The second temperature probe 32 may be disposed on the same charging base 21 or the same electrical connector 211 as the first temperature probe 31 that measures a high temperature (i.e., greater than the second temperature threshold). By collecting the temperature measured by the second temperature probe 32, the situation of the spread of the safety accident can be judged. Based on the spread of safety accidents, the power exchange station can take further measures. In step S162, when the temperature measured by the second temperature probe 32 continuously rises and is greater than the third temperature threshold, the second accumulated time may start counting. By monitoring the temperature condition at the second temperature probe 32, the condition of the spread of the safety accident can be better judged. In step S163, when the temperature measured by the second temperature probe 32 continuously rises and is greater than the third temperature threshold and the second accumulated time is greater than the third time threshold, the electrical connection between the charging base 21 on the peripheral side of the charging base 21 and the battery box 40 thereon at the second temperature probe 32 can be controlled to be disconnected, so that the safety accident caused by the diffusion of one charging base 21 to the peripheral side charging base 21 can be prevented from further expanding.
In some embodiments, as shown in fig. 2, the power plant control method further comprises:
in step S17, the aerosol-safety device 30 of the charging base 21 adjacent to the charging base 21 is triggered to cool down based on the temperature measured by the second temperature probe 32 being greater than the fourth temperature threshold and the second accumulated time being greater than the fourth time threshold.
In this embodiment, as shown in fig. 2, the power exchange station control method may further include step S17. When the second temperature probe 32 measures a high temperature (i.e., greater than the fourth temperature threshold) and has a duration greater than the fourth time threshold, it is indicated that a safety accident has occurred and there is a tendency for further diffusion at the electrical connection of the charging base 21 to the battery box 40. The second temperature probe 32 may be disposed on the same charging base 21 or the same electrical connector 211 as the first temperature probe 31 that measures a high temperature (i.e., greater than the second temperature threshold). In this way, the aerosol safety device 30 on the charging base 21 adjacent to the charging base 21 at a high temperature can be triggered to cool the charging base 21 on the periphery of the accident source charging base 21, so as to avoid further diffusion of the safety accident.
In some embodiments, as shown in fig. 2, the power plant control method further comprises:
in step S18, the warning device 11 sends out a warning signal based on the triggering of the aerosol safety device 30.
In this embodiment, as shown in fig. 2, the power exchange station control method may further include step S18. When the aerosol safety device 30 is triggered, the warning device 11 arranged in the power exchange station can generate a warning signal, so that the power exchange station manager and the driver of the power exchange vehicle can be reminded to take further measures.
In some embodiments, as shown in fig. 2, the power plant control method further comprises:
in step S19, the warning device 11 sends out a warning signal based on the temperature measured by the first temperature probes 31 of the at least two charging bases 21 being greater than the second temperature threshold.
In this embodiment, as shown in fig. 2, the power exchange station control method may further include step S19. When the temperature measured by the first temperature probes 31 of the at least two charging bases 21 is greater than the second temperature threshold, it is indicated that the plurality of charging bases 21 have potential safety hazards, and in order to avoid the occurrence of a safety accident, the warning device 11 disposed in the power exchange station can generate a warning signal, so that a manager of the power exchange station and a driver of the power exchange vehicle can be reminded to take further measures.
