Fig. 1 is a flow chart of a load factor evaluation method of a power exchange station according to an embodiment of the invention.
Specifically, in some embodiments of the present invention, as shown in fig. 1, a load factor evaluation method of a power exchange station includes:
s101, acquiring the service recovery speed and the service consumption speed of the power exchange station.
Specifically, in this embodiment, the service recovery speed of the power exchange station is related to factors such as the number of chargers and the average charging time of chargers of the power exchange station, the service consumption speed of the power exchange station is related to the number of power exchange channels, and further, the service recovery speed of the power exchange station can be determined according to factors such as the number of chargers and the average charging time of chargers of the power exchange station, and the service consumption speed of the power exchange station can be determined according to factors such as the number of power exchange channels.
S102, determining the theoretical maximum service times of the power exchange station according to the service recovery speed and the service consumption speed.
Specifically, in this embodiment, the theoretical maximum service number of the power exchange station refers to the service number that the power exchange station can provide in the preset period, and the theoretical maximum service number of the power exchange station is related to the service recovery speed and the service consumption speed of the power exchange station, so that the theoretical maximum service number of the power exchange station can be determined according to the service recovery speed and the service consumption speed, for example, the faster the service recovery speed and the service consumption speed of the power exchange station, the higher the service frequency of the power exchange station is, and at this time, the more the theoretical maximum service number of the power exchange station is.
S103, obtaining the actual service times of the power exchange station, and determining the load rate of the power exchange station according to the actual service times and the theoretical maximum service times.
Specifically, in this embodiment, the actual service number of the power exchange station refers to the service number of the power exchange station actually occurring in a preset period, where the actual service number of the power exchange station may be obtained through statistics of a database at the back end of the power exchange system, and further, a ratio of the actual service number to the theoretical maximum service number is calculated, and the ratio is determined as the load factor of the power exchange station.
In this embodiment, the ratio of the actual number of services to the theoretical maximum number of services is less than or equal to 1.
Further, in some embodiments of the present invention, as shown in fig. 2, obtaining a service recovery speed of the power exchange station includes:
s201, obtaining information of chargers of the battery exchange station, wherein the information of the chargers comprises the maximum number of chargers, average charging time length of the chargers and average charging time length of the chargers.
Specifically, in this embodiment, the charger information of the power exchange station may be obtained through a back-end database of the power exchange system, where the charger information includes a maximum number of chargers, an average charging duration of chargers, and an average charging duration of chargers.
The maximum number of the chargers refers to the maximum number of the chargers in the power exchange station, the average charging time length of the chargers refers to the average time length spent on taking the fully charged battery down from the chargers and replacing the fully charged battery on the power exchange vehicle, and the average charging time length of the chargers refers to the average time length spent on fully charging one to-be-charged battery by the chargers.
S202, determining the service recovery speed of the power exchange station according to the charger information of the power exchange station.
Specifically, in this embodiment, the information of the chargers for the battery exchange may be obtained through a database at the back end of the battery exchange system, where the information of the chargers includes the maximum number of chargers, the average battery exchange time length of the chargers, and the average charging time length of the chargers, and the service recovery speed of the battery exchange station is determined according to the following formula: service recovery speed of the battery exchange station= (maximum battery charger number-1) average battery charger time length/(battery charger average battery charger time length+battery charger average battery charger time length).
It should be noted that, in the above embodiment, the service recovery speed= (maximum number of chargers-1) ×average recovery speed of chargers, in which, since a battery is always in a battery-charging state and cannot be charged during the full-load operation of the device, the chargers in the battery-charging state are excluded by the calculation method of subtracting 1 from the maximum number of chargers, and in addition, the average recovery speed of chargers=average battery-charging duration of chargers/(average battery-charging duration of chargers+average battery-charging duration of chargers), it is understood that the average charge duration of chargers=average duration of chargers that it takes for a battery to be fully charged, and further, the calculation can be obtained based on the above formula: service recovery speed= (maximum number of chargers-1) average battery change duration/(average battery change duration of chargers+average battery charge duration of chargers).
It should be understood that, in the above embodiment, the service recovery speed of the power exchange station may be 1 unit/s, where the service recovery speed refers to the recoverable power exchange service capability of all the chargers of the power exchange station in normal operation, for example, assuming that the service recovery speed of the power exchange station a is 10 units/s and the average power exchange time length of the chargers is 100s, when the power exchange station a recovers for 100s, the power exchange station a may recover ten times of power exchange services, that is, the power exchange station a may exchange power for ten vehicles at the same time at most after 100s, and in addition, the invention may not specifically limit the service recovery speed of the power exchange station a and the average power exchange time length of the chargers.
Further, in some embodiments of the present invention, obtaining the service consumption rate of the power exchange station includes: and obtaining the number of the power exchanging channels of the power exchanging station, and determining the service consumption speed of the power exchanging station according to the number of the power exchanging channels.
Specifically, in this embodiment, the more the number of channels of the power exchange station is, the more vehicles the power exchange station can exchange power at the same time, for example, when there are two channels of power exchange, the power exchange station can exchange power for two vehicles at the same time, and for example, when there are three channels of power exchange, the power exchange station can exchange power for three vehicles at the same time, so the service consumption speed of the power exchange station can be determined by acquiring the number of channels of power exchange station according to the number of channels of power exchange.
It should be noted that when there are two power exchanging channels, the power exchanging station may perform power exchanging service for two power exchanging vehicles at the same time, at this time, the service consumption speed of the power exchanging station is 2 units/s, and for example, when there are three power exchanging channels, the power exchanging station may perform power exchanging service for three power exchanging vehicles at the same time, at this time, the service consumption speed of the power exchanging station is 3 units/s, and so on, and will not be described herein.
Further, in some embodiments of the present invention, determining a theoretical maximum number of services of the power exchange station based on the service restoration speed and the service consumption speed includes: and if the service recovery speed is smaller than the service consumption speed, determining the theoretical maximum service times of the power exchange station according to the initial service times and the service recovery speed.
Specifically, in this embodiment, if the service recovery speed is less than the service consumption speed, it is indicated that the service recovery speed of the power exchange station is insufficient to support all vehicles to be powered on for power exchange, and at this time, assuming that the foregoing preset period is 1 day, the number of service that can be recovered in one day can be determined by the service recovery speed, and then the initial number of service and the service recovery speed are used to determine the theoretical maximum number of service of the power exchange station.
The theoretical maximum service number is the initial service number plus the service number that the power exchange station can recover in one day, and it can be understood that the initial service number is the maximum number of backup batteries in the power exchange station, and the initial service number can be obtained from a database at the back end of the power exchange system or set by a worker of the power exchange station, where the service number that the power exchange station can recover in one day= (24×3600—number of chargers) average power exchange duration.
Further, in some embodiments of the present invention, determining a theoretical maximum number of services of the power exchange station based on the service restoration speed and the service consumption speed includes: and if the service recovery speed is greater than or equal to the service consumption speed, determining the theoretical maximum service times of the battery exchange station according to the average battery exchange time length of the battery charger.
Specifically, in this embodiment, if the service recovery speed is greater than or equal to the service consumption speed, it is indicated that the service recovery speed of the power exchange station is sufficient to support a plurality of vehicles to be exchanged for uninterrupted power exchange, and at this time, assuming that the aforementioned preset period is 1 day, the number of service that the power exchange station can recover in one day can be determined by the service recovery speed, that is, when the service recovery speed is greater than or equal to the service consumption speed, the theoretical maximum number of service is equal to the number of service that the power exchange station can recover in one day.
It should be noted that, the theoretical maximum service number can be obtained by the following formula: theoretical maximum number of service = 24 x 60/average battery change duration of the battery charger.
The following describes the specific flow steps of the load factor evaluation method of the power exchange station according to the present invention with reference to fig. 3 and an embodiment of the present invention, and as shown in fig. 3, the specific steps are as follows:
