Along with the improvement of environmental awareness, new energy vehicles are attracting more attention, and the heavy truck also uses an electric driving mode, so that the carbon emission is reduced, and the environment is protected. The electric heavy truck adopts a power conversion mode to realize the reduction of the time which cannot work due to charging, can also rapidly carry out energy supply, is very suitable for operation in a fixed scene or a closed scene, and has certain requirements on adjustment.

When a common electric vehicle is subjected to power exchange scheduling, the cloud server acquires position information and state information of a plurality of power exchange stations, acquires position information, residual electric quantity information and destination information of each vehicle, and further judges whether a battery pack needs to be replaced or not. And if the battery pack needs to be replaced, determining the optimal driving path, the power change time and the power change station of the vehicle according to the acquired information, and sending the optimal driving path, the power change time and the power change station to the intelligent interaction terminal.

Or when the vehicle is in the queue, the reservation number and the reserved power change time are sent to the vehicle according to the queuing condition, and after the reservation is successful, the vehicle is started to a charging and power change station to change the battery. The existing vehicle power change scheduling method considers each vehicle independently, when more vehicles need to be changed, the queuing condition is serious, so that the power change time is longer, and the power change efficiency is lower.

Aiming at the problems in the prior art, the inventor finds that in the process of researching the power change scheduling method of the heavy card, the heavy card can change power when the battery pack of the heavy card reaches the SOC power change threshold value by dynamically adjusting the State of charge (SOC) threshold value of each heavy card. In the process of dynamically adjusting the SOC power-changing threshold value of each heavy card, comprehensively considering that the SOC power-changing threshold value is larger than or equal to a preset lowest power-changing threshold value, and ensuring that the heavy card cannot stop running due to insufficient electric quantity; when the SOC power-changing threshold is considered to be larger than or equal to the lowest power-changing threshold, the replaceable battery pack corresponding to the heavy truck can be fully charged before the heavy truck is powered-up, so that the power-changing waiting time is reduced; and the waiting time of the heavy truck at the power exchange station is considered to be smaller than a time threshold value, so that the waiting time is reduced.

s201: and acquiring the discharge rate of each heavy card according to the historical operation data of each heavy card.

The T-Box is arranged on the heavy card, and in the running process of the heavy card, running data can be sent to the power conversion management platform through the T-Box, so that the power conversion management platform can receive the running data of the heavy card reported by the T-Box of each heavy card, and the running data comprise: and the connection time of the heavy truck and the battery pack in the operation process of each heavy truck, the SOC value of the battery pack before the operation of each heavy truck, the SOC value of the battery pack after the operation of each heavy truck and the load capacity in the operation process of each heavy truck. And the power conversion management platform sends the received operation data of each heavy card to the server.

In the step, after receiving and storing the real-time operation data of each heavy card uploaded by the power conversion management platform, the server can calculate the discharge rate of each heavy card by taking the real-time operation data before the current moment as the historical operation data due to storing the real-time operation data.

The result of subtracting the SOC value of the battery pack after each heavy card is operated from the SOC value of the battery pack before each heavy card is operated can be divided by the connection time of the heavy card and the battery pack in the operation process of each heavy card, and the result is used as the discharge rate of one operation process of each heavy card. And inputting the discharge rate of the multiple operation processes and the load capacity of the heavy truck in the operation process into a preset heavy truck discharge rate prediction model to obtain the current discharge rate of each heavy truck.

The running data can also comprise real-time voltage, current and temperature of a battery pack connected with the heavy truck in the running process of each heavy truck, the speed of the heavy truck in the running process of each heavy truck, data corresponding to the vehicle state and the like; wherein the vehicle state includes: operating conditions, flameout conditions, etc.

It should be noted that, the preset heavy-duty card discharge rate prediction model is set in the server by the staff before the heavy-duty card power-switching scheduling is performed, so as to obtain the discharge rate of each heavy-duty card. The heavy truck discharge rate prediction model may be used for obtaining the discharge rate of each heavy truck by averaging according to the discharge rate of the multiple running processes; the relation between the discharge rate and the load capacity can be obtained by fitting according to the discharge rate of the multiple operation processes and the load capacity of the heavy truck in the operation process, and the discharge rate of each heavy truck can be obtained by combining the current load capacity of each heavy truck. The embodiment of the invention does not specifically limit the heavy card discharge rate prediction model, and can be set according to actual conditions.

S202: and acquiring the charging rate of each battery pack according to the historical charging data of the battery pack in the current power exchange station and the historical charging data of the charging pile.

The battery pack charging system comprises a battery pack, a battery pack charging pile, a battery management system, a battery pack charging system and a battery pack charging pile, wherein the battery pack charging system is used for storing charging data of the battery pack, and the battery pack charging pile is used for storing charging data of the battery pack, and the battery pack charging system is used for storing charging data of the battery pack, and the battery pack charging pile is used for charging the battery pack charging system, and the battery pack charging system is used for charging the battery pack and the battery pack charging pile, and the battery pack charging management system is used for receiving charging data of the battery pack and the charging pile. Charging time in the charging process of each battery pack, an SOC value before charging of each battery pack, an SOC value after charging of each battery pack, and charging data of a charging pile comprise: a current value during charging of each battery pack, a voltage value during charging of each battery pack; the charging data of the charging stake may further include: and whether to connect with the battery pack. And the battery replacement management platform sends the received charging data of the battery pack and the charging data of the charging pile to the server.

In this step, after receiving and storing the charging data of the battery packs in the battery exchange station and the charging data of the charging pile uploaded by the battery exchange management platform, the server stores the charging data, so that the charging data before the current moment can be used as historical operation data, and the charging rate of each battery pack can be calculated.

The result of subtracting the SOC value after each battery pack charge from the SOC value before each battery pack charge may be divided by the charge time during each battery pack charge as the charge rate of one charge process per battery pack. And inputting the charging rate of the multiple charging processes and the charging data of the charging pile in the charging process into a preset battery pack charging rate prediction model to obtain the current charging rate of each battery pack.

It should be noted that, the preset battery pack charging rate prediction model is set in the server by the staff before the heavy-duty power-on schedule is performed, so as to obtain the charging rate of each battery pack. For example, the battery pack charge rate prediction model may be configured to average the charge rates of multiple charging processes to obtain a current charge rate of each battery pack; the charging rate of the battery pack can be obtained by fitting according to the charging rate of the multiple charging processes and the current value and the voltage value of each battery pack in the charging process to obtain the relationship between the charging rate and the current value and the voltage value, and combining the current charging voltage value and the current value of each battery pack. The embodiment of the invention does not specifically limit the battery pack charge rate prediction model, and can be set according to actual conditions.

In this step, after the server obtains the discharging rate of each heavy card and the charging rate of each battery pack, the server may preset a charging scheduling policy in combination with the current remaining SOC value of the battery pack installed on each heavy card, to determine the SOC electricity-changing threshold of each heavy card. The preset charging scheduling strategy comprises the following steps: and dynamically adjusting the SOC power change threshold of each heavy card so that the SOC power change threshold of the heavy card is larger than or equal to a preset minimum power change threshold, and fully charging a replaceable battery pack corresponding to the heavy card before the heavy card is charged when the SOC power change threshold of the heavy card is larger than or equal to the preset minimum power change threshold, wherein the waiting power change time of each heavy card at a power change station is smaller than a preset time threshold. And then the SOC power change threshold value can be sent to a power change management platform.

The preset lowest power-changing threshold value is set in the server by a worker before the power-changing scheduling of the heavy truck and is used for being compared with the SOC power-changing threshold value of the heavy truck. The minimum power-exchanging threshold value can be 30% or 20%, and the embodiment of the invention does not specifically limit the minimum power-exchanging threshold value and can be set according to actual conditions.

It should be noted that, the preset charging schedule policy is set in the server by the staff before the power-saving schedule of the heavy truck, and is used for determining the SOC power-saving threshold value of each heavy truck.

It should be noted that, the preset time threshold is set in the server by the staff before the power exchange scheduling of the heavy truck, and is used for comparing the power exchange waiting time of each heavy truck in the power exchange station. The preset time threshold may be 5 minutes, 10 minutes or 0 minutes, and the embodiment of the present invention does not specifically limit the preset time threshold and may be set according to practical situations.

Because the power change management platform can send the operation data of the heavy card to the server, the server can send a power change instruction to the heavy card through the power change management platform when the residual SOC value of the battery pack of any heavy card reaches the SOC power change threshold value of the heavy card, and then the heavy card returns to the power change station for power change.

S205: and receiving and displaying the SOC power-on-chip threshold of each heavy card sent by the server on a graphical user interface.

In the step, after the server sends the SOC power-exchanging threshold value of each heavy card to the power-exchanging management platform, the power-exchanging management platform receives the SOC power-exchanging threshold value of each heavy card sent by the server and displays the SOC power-exchanging threshold value on a user graphical interface, and a dispatcher can monitor the SOC power-exchanging threshold value of each heavy card.

S206: and sending a power change instruction to the heavy card when the residual SOC value of any heavy card reaches the SOC power change threshold value of the heavy card according to the operation data of each heavy card acquired in real time.

In the step, after the power conversion management platform receives the SOC power conversion threshold value of each heavy card, because each heavy card can report operation data to the power conversion management platform in real time, the power conversion management platform can send a power conversion instruction to the heavy card when the residual SOC value of any heavy card reaches the SOC power conversion threshold value of the heavy card according to the operation data of each heavy card acquired in real time, and the heavy card receives the power conversion instruction and returns to the power conversion station for power conversion.

It should be noted that after the heavy truck receives the power change instruction, the sound of reminding the power change can be played through the loudspeaker in the automobile to remind the driver to return to the power change station for power change, the power change reminding information can be displayed on the instrument panel to remind the driver to return to the power change station for power change, and the driver can perform feedback operation on the instrument panel after receiving the power change reminding, so that the power change management platform can determine that the driver receives the power change instruction. The embodiment of the invention does not limit the mode of reminding the driver to change electricity, and can be selected according to actual conditions.

If the power change management platform detects that the heavy truck does not return to the power change station for power change according to the power change instruction after sending the power change instruction to the heavy truck, or when power change abnormality occurs, pushing a power change abnormality reminding message on a graphical user interface so as to enable a dispatcher to check and contact with a driver of the heavy truck and command the heavy truck to return to the power change station for power change.

According to the power change scheduling method for the heavy cards, through dynamic adjustment of the SOC power change threshold value of each heavy card so that the SOC power change threshold value of each heavy card is larger than or equal to the preset lowest power change threshold value, when the SOC power change threshold value of each heavy card is larger than or equal to the preset lowest power change threshold value, the exchangeable battery pack corresponding to the heavy card can be fully charged before the heavy card is charged, the waiting power change time of each heavy card in a power change station is smaller than the charging scheduling strategy of the preset time threshold value, and the SOC power change threshold value of each heavy card is determined by combining the residual SOC value of the battery pack installed on each heavy card, the discharging rate of each heavy card and the charging rate of each battery pack. And when the residual SOC value of the heavy truck reaches the SOC power-changing threshold value, power is changed. Compared with the prior art, when more vehicles exist, the power conversion waiting time is long, the power conversion time is effectively reduced, and the power conversion efficiency is improved.

Fig. 3 is a schematic flow chart of a second embodiment of a power-changing scheduling method for heavy cards, as shown in fig. 3, on the basis of the first embodiment, step S203 specifically includes the following steps:

s301: according to the residual SOC value of the battery pack installed on each heavy truck, the discharging speed of each heavy truck and the lowest power-changing threshold value, the discharging duration of each heavy truck is obtained, and all the heavy trucks are sequenced according to the sequence from small to large in discharging duration.

In the step, after obtaining the discharge rate of each heavy card and the charge rate of each battery pack, the server divides the result of subtracting the preset lowest power-changing threshold value from the residual SOC value of the battery pack installed on each heavy card by the discharge rate of the heavy card to obtain the discharge duration of each heavy card. And then sequencing all the heavy cards according to the sequence from the small discharge time length to the large discharge time length, so that the SOC power-changing threshold value can be determined for the sequenced heavy cards.

S302: and calculating a discharging time difference value between the heavy card and an M-th heavy card behind the heavy card for each heavy card in the first M heavy cards after sequencing, wherein M is the number of battery packs in the power exchange station.

In the step, after the heavy cards are ordered, aiming at each heavy card in the first M heavy cards after the ordering, M is the number of battery packs in a power exchange station, the discharging time length of the M heavy cards behind the heavy card is reduced by the discharging time length of the heavy card, so as to obtain a discharging time length difference value, and further, the discharging time length difference value can be compared with the charging time length to determine the SOC power exchange threshold value of the heavy card.

S303: and according to the charging rate of the battery pack of the heavy truck, calculating the charging time length from the lowest power-changing threshold value to the preset highest charging threshold value of the battery pack of the heavy truck.

In the step, after the server calculates the difference value of the discharging time, for each heavy card in the first M heavy cards after sorting, dividing the result of subtracting the lowest power-changing threshold from the preset highest charging threshold of the battery pack of the heavy card by the charging rate of the battery pack to obtain the charging time of the battery pack, and then comparing with the discharging time to determine the SOC power-changing threshold of the heavy card.

It should be noted that, the preset highest charging threshold is set in the server by the staff before the power-changing schedule of the heavy truck, and is used for determining the highest SOC value that the charging energy of the battery pack reaches, and She Yongji calculates the charging duration of the battery pack. The highest charging threshold may be 100% or 90%, and the embodiment of the present invention does not specifically limit the highest charging threshold, and may be set according to practical situations.

S304: and determining the SOC power-changing threshold of the heavy truck according to the discharging time difference and the charging time.

In the step, after the server calculates the discharging time difference and the charging time, the SOC power-changing threshold value of the heavy truck can be determined.

If the difference value of the discharging time length is greater than or equal to the charging time length, the SOC power-changing threshold value of the heavy truck is set to be the lowest power-changing threshold value

If the discharging time difference is smaller than the charging time, the SOC power-on-chip threshold of the heavy truck is calculated according to the following formula:

wherein SOC is _{low_i} Indicating the SOC power-on threshold value of the ith heavy card in the first M heavy cards, wherein i is less than or equal to M,indicating the discharge rate, SOC, of the ith heavy card in the previous M heavy cards _max Representing the highest charge threshold, +.>Indicating the charge rate, SOC, of the battery pack mounted on the ith heavy card of the first M heavy cards _i Representing the current SOC value, T of the battery pack installed by the ith heavy card in the previous M heavy cards _i+M And (5) representing the time length from the current SOC value to the lowest power-changing threshold value of the battery pack currently installed in the (i+M) th heavy truck.

Taking one heavy card of M heavy cards as an example for illustration, when the difference value of discharging time is greater than or equal to the charging time, the heavy card is illustrated to change electricity when the SOC value of the battery pack reaches the lowest electricity changing threshold, and the battery pack can be fully charged when the M heavy card behind the heavy card is replaced by the battery pack replaced by the heavy card. And under the condition that the discharging time difference value is smaller than the charging time, the fact that the heavy truck changes the power when the SOC value of the battery pack reaches the SOC power change threshold value is indicated, and when the M-th heavy truck behind the heavy truck changes the battery pack under the heavy truck, the battery pack can be fully charged.

In addition, for the heavy card having not determined the SOC power conversion threshold value through steps S301 to S304, the SOC power conversion threshold value is determined as the lowest power conversion threshold value.

After obtaining the SOC power-changing threshold value of each heavy card, the server sends the SOC power-changing threshold value to a power-changing management platform so as to schedule the heavy card to change power.

According to the power change scheduling method for the heavy truck, the SOC power change threshold value of the heavy truck is determined by comprehensively considering the discharging time length of the heavy truck, the charging time length of the battery pack installed by the heavy truck and the discharging time length of the M-th heavy truck behind the heavy truck, namely, the heavy truck is ensured not to stop running due to insufficient electric quantity, and the battery with the M-th heavy truck behind the heavy truck capable of being replaced with full electricity is also determined, so that the continuous working capacity of the heavy truck is improved, the power change waiting time is shortened, and the power change efficiency is improved.

Fig. 4 is a schematic flow chart of a third embodiment of a power-changing scheduling method for a heavy truck, as shown in fig. 4, on the basis of the second embodiment, after determining an SOC power-changing threshold value of the heavy truck according to a discharging time difference value and a charging time, the power-changing scheduling method for the heavy truck further includes the following steps:

s401: and acquiring the charging completion time from the current SOC value to the highest charging threshold value of the replaceable battery pack to be replaced on the heavy truck.

After the server obtains the SOC power-on threshold of the heavy truck, the SOC power-on threshold can be further updated.

In this step, for the replaceable battery pack to be replaced on the heavy card, the replaceable battery pack includes an idle battery pack in the battery replacing station or a battery pack of the heavy card that is replaced before the heavy card, the result of subtracting the current SOC battery replacing threshold value of the battery pack from the highest charging threshold value is divided by the charging rate of the battery pack, so as to obtain the charging duration of the battery pack, and the charging completion time can be obtained in combination with the current time. And then, the charging scheduling strategy can be preset according to the charging completion time of the replaceable battery pack, and the SOC power-changing threshold value and the power-changing time of the heavy truck are updated.

S402: and calculating the first power-changing time of the heavy truck according to the discharging rate of the heavy truck and the SOC power-changing threshold value of the heavy truck.

In this step, after obtaining the charging completion time, the server divides the result of the SOC power conversion threshold of the heavy card of the current SOC value of the battery pack installed by the heavy card by the discharging rate of the heavy card to obtain the power conversion duration, and combines with the current time to obtain the first power conversion time, where the first power conversion time is the time when the battery pack installed by the heavy card reaches the SOC power conversion threshold, and further the second power conversion time needs to be calculated.

S403: and calculating the second power change time of the heavy card according to the discharge rate of the heavy card and the lowest power change threshold value.

In the step, after the server calculates the first power change time, dividing the current SOC value of the battery pack installed on the heavy card by the discharging rate of the heavy card to obtain the power change time length, and combining the current time to obtain the second power change time, wherein the second power change time is the time when the battery pack installed on the heavy card reaches the lowest power change threshold value. And then the SOC power change threshold value and the power change time of the heavy truck can be updated according to the charging completion time, the first power change time and the second power change time.

S404: and updating the SOC power change threshold and the power change time of the heavy truck according to the charging completion time, the first power change time and the second power change time.

In this step, after obtaining the charging completion time, the first power change time, and the second power change time, the server may update the SOC power change threshold and the power change time of the heavy card.

If the charging completion time is later than the first power changing time and is earlier than the second power changing time, the power changing time is determined to be the charging completion time;

and if the charging completion time is later than or equal to the second power changing time, determining the power changing time as the second power changing time.

The power-changing time is reduced by the current time to obtain the power-changing time length, the power-changing time length is multiplied by the discharging rate of the truck to obtain the SOC difference value, and the current SOC value of the battery pack installed on the heavy truck is reduced by the SOC difference value to obtain the SOC power-changing threshold value of the heavy truck. And then the updated SOC power change threshold and the power change time are sent to a power change management platform so as to schedule the heavy truck to change power.

According to the power change scheduling method for the heavy truck, under the condition that the SOC power change threshold value of the heavy truck is ensured to be larger than or equal to the lowest power change threshold value, the power change time is further considered, so that when the truck returns to the power change station in the power change time, the replaceable battery pack to be replaced on the heavy truck can be fully charged, the continuous operation capability of the heavy truck is improved, and the power change efficiency is improved.

Fig. 5 is a schematic flow chart of a fourth embodiment of a power-changing scheduling method for a heavy truck, as shown in fig. 5, based on the third embodiment, after updating the SOC power-changing threshold and the power-changing time of the heavy truck according to the charging completion time, the first power-changing time and the second power-changing time, the power-changing scheduling method for the heavy truck further includes the following steps:

s501: and calculating the interval time between the power changing time of the heavy card and the power changing time of the L-th heavy card before the heavy card aiming at each heavy card after the L-th heavy card in the first M heavy cards, wherein L is the number of simultaneously power-changeable vehicles supported by a power changing station.

After updating the SOC power-changing threshold value and the power-changing time of the heavy truck once, the server can further continuously update the SOC power-changing threshold value and the power-changing time.

In this step, for each heavy card after the L-th heavy card in the first M heavy cards, the interval time between the power change time of the heavy card and the power change time of the L-th heavy card before the heavy card is calculated, where L is the number of vehicles capable of simultaneously changing power supported by the power change station, so that the power change time of the heavy card can be updated.

S502: and according to the interval time, the time difference between the primary power exchanging time of the power exchanging station and the preset time threshold value is used for updating the power exchanging time of each heavy card in sequence.

In the step, after the server obtains the interval time, judging whether the interval time is greater than or equal to the primary power exchange time of the power exchange station, and if the interval time is greater than or equal to the primary power exchange time, not updating the power exchange time of the heavy card; if the time is smaller than the primary power change time, the power change time of the heavy truck is updated so that the interval time is larger than or equal to the difference value between the primary power change time of the power change station and the preset time threshold value, and is smaller than or equal to the primary power change time of the power change station.

Illustratively, L is 5, M is 7, the power change time of the first heavy card is ten-point integer, the power change time of the sixth heavy card is ten-point, the interval time is ten minutes, the primary power change time of the power change station is fifteen minutes, and if the preset time threshold is two minutes, the power change time of the sixth vehicle after updating is between twenty-three minutes and twenty-five minutes, and the power change time can be selected from twenty-three minutes and twenty-five minutes.

It should be noted that, the above example only illustrates the power change time of updating the heavy card; when the primary power exchange time of the power exchange station is the time from the disassembly of the battery pack to the completion of the installation of the battery pack when the heavy truck is used for carrying out power exchange at the power exchange station, the time is set in a server by a worker before the heavy truck power exchange scheduling is carried out, and the time is used for updating the power exchange time of the heavy truck; l is the number of vehicles capable of simultaneously changing electricity supported by the electricity changing station, L is set in a server by staff before the electricity changing scheduling of the heavy truck and is used for updating the electricity changing time of the heavy truck.

It should be noted that, if the pre-update power change time is the time when the battery pack on the heavy card reaches the lowest power change threshold, after the updated power change time is determined, the heavy card can stop running when running to the lowest threshold, and return to the power change station for power change when reaching the updated power change time; if the SOC value of the battery pack is lower than the lowest power change threshold value when the heavy truck is operated to the updated power change time, the heavy truck can stop operation when the heavy truck is operated to the lowest power change threshold value, and the battery pack returns to the power change station to change power when the updated power change time is reached.

It should be noted that, the power change scheduling scheme of the heavy truck provided by the invention may be that the SOC power change threshold value of the heavy truck is determined only according to the first embodiment, and the scheduling is performed according to the SOC power change threshold value of each heavy truck, after the SOC power change threshold value is determined according to the second embodiment, the SOC power change threshold value is updated once, the scheduling is performed according to the SOC power change threshold value after the once update, and after the SOC power change threshold value is updated once according to the third embodiment, the SOC power change threshold value is updated again, and the scheduling is performed according to the SOC power change threshold value after the twice update.

According to the power change scheduling method for the heavy cards, the SOC power change threshold and the power change time of each heavy card after the L-th heavy card in the M heavy cards are updated according to the number of vehicles capable of being simultaneously changed and the primary power change time of the power change station supported by the power change station, so that the waiting power change time of the heavy card in the power change station is smaller than the time threshold, the waiting power change time of the heavy card is effectively reduced, and the power change efficiency is improved.
