As shown in fig. 1, the electric vehicle charging control device provided by the application comprises an electric quantity detection module 11, a vehicle positioning module 12, a processing module 13, a first communication module 14 and a second communication module 200. The electric quantity detection module 11, the vehicle positioning module 12, the first communication module 14 and the processing module 13 are all installed in the electric automobile 1, and the second communication module 200 is installed in the charging pile 2. The electric quantity detection module 11, the vehicle positioning module 12 and the first communication module 14 are all connected with the processing module 13, and the first communication module 14 is also connected with the second communication module 200 in a wireless manner. The number of charging piles 2 in fig. 1 is only one.

The power detection module 11 is configured to detect current power information of the electric vehicle 1 and send the current power information to the processing module 13. The processing module 13 is configured to determine a maximum running distance of the electric vehicle 1 according to the current electric quantity information.

Specifically, the electric quantity detection module 11 may detect the current electric quantity information of the electric vehicle 1 in real time or at intervals, for example, at intervals of 10 minutes, and send the current electric quantity information to the processing module 13, and the processing module 13 determines the maximum running distance of the electric vehicle 1 according to the current electric quantity information in real time. Alternatively, the processing module 13 determines the maximum running distance of the electric vehicle 1 at intervals, for example, at intervals of 30 minutes, based on the current power information transmitted from the power detection module 11. Still alternatively, when the processing module 13 detects that the electric quantity value in the current electric quantity information sent by the electric quantity detection module 11 is smaller than the first threshold, for example, smaller than 40 percent, the maximum running distance of the electric automobile 1 is determined according to the current electric quantity information.

The vehicle positioning module 12 is configured to obtain a current location of the electric vehicle 1 and send the current location to the processing module 13. The processing module 13 is further configured to determine the first range according to the current location and the maximum travel distance.

The first communication module 14 is configured to determine one or more first charging piles within a first range of the charging piles 2 through communication with the second communication module 200. For example, the first communication module 14 is configured to communicate with the second communication modules 200, and send the location of the charging pile 2 corresponding to each second communication module 200 to the processing module 13, so that the processing module 13 determines one or more first charging piles located within the first range of the charging piles 2.

The processing module 13 is further configured to determine that a first charging pile is charging the electric vehicle 1.

The first communication module 14 and the second communication module 200 may communicate with each other by ZigBee, WIFI, bluetooth, or the like, which is not limited in this embodiment.

In this embodiment, the processing module 13 may determine the maximum running distance that the electric vehicle 1 can still run according to the current electric quantity information sent by the electric quantity detection module 11, and the processing module 13 may determine the first range according to the maximum running distance and the current location sent by the vehicle positioning module 12, so as to determine a first charging pile to charge the electric vehicle 1 in the first range. In this way, the electric vehicle 1 can be charged in time before the electric power is exhausted without affecting the travel of the user.

In some embodiments, the apparatus may further include an alarm module, for example, when the processing module 13 detects that the power value in the current power information sent by the power detection module 11 is smaller than the first threshold, the processing module 13 controls the alarm module to alarm, for example, the alarm module may prompt the user that the electric automobile 1 needs to be charged through voice, or prompt the user that the electric automobile 1 needs to be charged through flashing light with different colors.

In some embodiments, the vehicle positioning module 12 may be further configured to obtain the current location of the electric vehicle 1 after the alarm module alarms, and send the current location to the processing module 13.

In some embodiments, FIG. 2 is a schematic illustration of a first range determined by some embodiments of the application. Referring to fig. 2, to determine the first range, the processing module 13 is specifically configured to: and determining a first circle C taking the current position A as a circle center and taking the maximum running distance B as a radius, and a first range being the inner part of the first circle C.

It should be noted that the current position a may be regarded as a center point between four wheels at the current position of the electric vehicle 1. In the figure, the charging pile 2 located in the first circle C is a first charging pile 21, and the center positions of the charging pile 2 and the first charging pile 21 are both the first position D.

In this embodiment, the first charging pile 21 is located within the first range, so that the electric vehicle 1 can reach the first charging pile 21 before the electric quantity is exhausted.

In some embodiments, the apparatus may further include an enabling monitoring module, provided on the charging post 2, for monitoring whether the charging post 2 is in an enabled state, and it should be understood that the first charging post 21 in the above embodiment is the charging post 2 in the enabled state.

Referring to fig. 2, in some embodiments, the apparatus may further include a user input module located within the electric vehicle 1 and connected with the processing module 13. The user input module is configured to obtain a destination location G of the user and send the destination location G to the processing module 13. For example, the user may input the destination location G to the user input module by voice or text, or the like.

If there are a plurality of first charging piles 21, for example, 3 first charging piles 21 in fig. 2. The processing module 13 is specifically configured to: a first sum of the first distance E of each first charging stake 21 and the second distance F of the first charging stake 21 is calculated. The first distance E is a distance from the first charging pile 21 to the current position a of the electric vehicle 1. Referring to fig. 2, the first distance E may be a distance of the electric vehicle 1 from the first location D to the current location a. The second distance F is a distance from the first charging stake 21 to the destination location G of the electric vehicle 1. Referring to fig. 2, the second distance F may be a distance of the electric vehicle 1 from the first location D to the destination location G. The first charging stake 21 corresponding to the smallest first sum of the first sums is determined to charge the electric vehicle 1.

It should be understood that one first sum is the sum of the first distance E and the second distance F of the same first charging pile 21. For example, in fig. 2, the first sum is 3, and assuming that the 3 first sums are 6 km, 10 km, and 13 km, respectively, the processing module 13 determines that the first charging pile 21 corresponding to the first sum of 6 km charges the electric vehicle 1.

It will be appreciated that the two charging piles 2 located outside the first range in fig. 2 are not available for charging the electric vehicle 1. If the first charging pile 21 is one, the processing module 13 may directly determine that the first charging pile 21 charges the electric vehicle 1.

In this embodiment, by determining that the first charging pile 21 corresponding to the smallest first sum of the first sums charges the electric vehicle 1, the electric vehicle 1 can be charged before the electric quantity is exhausted, and the distance that the electric vehicle 1 needs to run for charging can be reduced.

In some embodiments, the apparatus may further comprise an analysis module. A charging pile 2 is fitted with an analysis module. The analysis module is used for recording previous charging information of the charging pile 2, the charging information at least comprises the number of the electric vehicles 1 charged by the charging pile 2 in each period, and the analysis module is also used for determining the waiting time length of the electric vehicles 1 charged by the charging pile in each period according to the charging information.

For example, the analysis module of one charging pile 2 determines that the number of electric vehicles 1 charged by the charging pile 2 is 3 from 7 to 8 am each day according to the previous charging information, and the waiting time is 3 minutes; the number of electric vehicles 1 charged by the charging pile 2 is 5 and the waiting time is 5 minutes, which are determined from the conventional charging information from 8 to 9 am each day. And the electric automobile 1 to be charged by the user continues to run at the current speed for estimated 8 points 45 minutes to reach the charging pile 2, so the user uses the charging pile 2 to charge for estimated waiting time of 5 minutes.

It is understood that the analysis module may send the waiting time period of the electric vehicle 1 charged with the charging pile 2 for each period to the processing module 13 through the second communication module 200 and the first communication module 14.

In this way, in the present embodiment, by installing the analysis module at the charging pile 2 and determining the waiting time period of the electric vehicle 1 charged with the charging pile 2 for each period according to the analysis module, it is possible to know whether waiting and the time to predict waiting are required when charging with the charging pile 2 for a certain period.

In some embodiments, the charging pile 2 may further include a vehicle detection module, configured to detect the number of electric vehicles 1 passing through each period of the road section where the charging pile 2 is located, and establish, through the analysis module, a relationship between the number of electric vehicles 1 passing through each period of the road section where the charging pile 2 is located and the number of electric vehicles 1 charged by the charging pile 2 in each period. If the vehicle detection module detects that the number of electric vehicles 1 passing through the road section where the charging pile 2 is currently located suddenly increases beyond the second threshold value than before, for example, the second threshold value is 50, and the relationship between the number of electric vehicles 1 passing through each period and the number of electric vehicles 1 charged with the charging pile 2 each period by the road section where the charging pile 2 is located before determines that the waiting period may exceed a third threshold value, for example, the third threshold value is 20 minutes. The processing module 13 may determine that the electric vehicle 1 is not charging the charging stake 2. If the processing module 13 has previously determined that the charging pile 2 charges the electric vehicle 1, a first charging pile 21 may be redetermined according to the process of determining that the first charging pile 21 charges the electric vehicle 1 by the electric vehicle charging control device in the foregoing embodiment.

In some embodiments, the processing module 13 is further configured to determine, according to each first sum value, a corresponding driving duration of the electric vehicle 1 at the same speed.

In this embodiment, the estimated time period required for reaching each first charging pile 21 may be determined according to the driving time period, so as to select the most suitable first charging pile 21 to charge the electric vehicle 1 according to the user's requirement.

In some embodiments, the processing module 13 is further configured to calculate a second sum value of the waiting time and the driving time corresponding to each first charging pile 21, and the processing module 13 is further configured to determine a first charging pile 21 corresponding to a smallest second sum value of the second sum values to charge the electric vehicle 1.

In this embodiment, the processing module 13 determines the first charging pile 21 corresponding to the smallest second sum value of the second sum values to charge the electric vehicle 1, so that the time required for charging the electric vehicle 1 can be reduced.

In some embodiments, the user input module is further configured to obtain a maximum expected duration of the user, and the processing module 13 is further configured to calculate a second sum of the waiting duration and the driving duration corresponding to each first charging peg 21. The processing module 13 is further configured to determine the first charging pile 21 corresponding to the second sum value less than or equal to the maximum expected duration as the target charging pile. The processing module 13 is further configured to determine that a target charging pile with a minimum first sum value of the target charging piles charges the electric vehicle 1.

It should be appreciated that if the second sum values are both greater than the maximum desired duration, the processing module 13 may select the first charging peg 21 corresponding to the smallest second sum value to charge the electric vehicle 1. If there is only one target charging stake, the processing module 13 determines that the target charging stake is charging the electric vehicle 1.

In some embodiments, in order to save the charging time of a plurality of electric vehicles 1 to be charged, the plurality of electric vehicles 1 to be charged may be all connected in series on the charging connection line of the same charging gun of the same charging pile 2. In this way, by controlling the opening and closing of the relay of each electric vehicle 1, it is possible to sequentially charge a plurality of electric vehicles 1 to be charged, which are connected in series on the charging connection line of the same charging gun of the same charging pile 2.

Specifically, the electric vehicle charging control device may further include a control platform for communicating with the first communication module 14 to obtain the remaining power H of each electric vehicle 1 that has reached the charging stake 2. Assuming that the electric quantity when each electric automobile 1 is fully charged is the total electric quantity I, and the electric quantity available per hour by a single charging gun of the charging pile 2 is the power supply quantity J, the time required for fully charging each electric automobile 1 is t:

the control platform is also used to communicate with the second communication module 200 to obtain the total length of time T for which a single charging gun of the charging stake 2 is chargeable. The number n of vehicles with which the single charging guns of the charging pile 2 can be connected in series can be determined by T being more than or equal to t1+t2+t3+ … +tn. Wherein t1 is the time required for full charge of the first electric automobile 1 connected in series, t2 is the time required for full charge of the second electric automobile 1 connected in series, t3 is the time required for full charge of the third electric automobile 1 connected in series, and tn is the time required for full charge of the nth electric automobile 1 connected in series.

The electric vehicle charging control device may further include a battery management module disposed in the charging post 2 and a main relay disposed in the charging connection line, the battery management module being connected to the main relay, the main relay being connected to the relay of each electric vehicle 1 connected in series.

Assuming that the number of electric vehicles 1 in which a single charging gun can be connected in series is determined to be 3, the relay of the first electric vehicle 1 is a first relay, the relay of the second electric vehicle 1 is a second relay, and the relay of the third electric vehicle 1 is a third relay.

In practical application, the battery management module may control the main relay to turn on the first relay to charge the first electric vehicle 1, and when the first electric vehicle 1 is charged, the second electric vehicle 1 and the third electric vehicle 1 may be connected in series with the first electric vehicle 1 on a charging connection line of the same charging gun, and wait for charging.

When the first electric vehicle 1 finishes charging, the first communication module 14 may send a charged signal to the control platform, and the control platform receives the charged signal and sends the charged signal to the battery management module through the second communication module 200. After receiving the charged signal sent by the first electric automobile 1, the battery management module controls the main relay to close the first relay and open the second relay to charge the second electric automobile 1. Similarly, after receiving the charged signal sent by the second electric automobile 1, the battery management module controls the main relay to close the second relay, opens the third relay, and charges the third electric automobile 1 until the third electric automobile 1 is full, and the battery management module controls the main relay to close the third relay. In this way, the electric vehicle 1 to be charged is already connected with the charging gun before charging, so that the purpose of saving charging time can be achieved.
