Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

Aiming at the problem of how to realize charging of a new energy automobile, an embodiment of the application provides a new energy automobile charging method. It should be noted that, in the embodiment of the present specification, a charging process of a new energy vehicle is described by taking charging of an electric vehicle as an example, in other embodiments, the new energy vehicle may be a vehicle in an energy mode other than an electric vehicle, and the charging process may be another energy compensation process other than the charging process.

Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application. As shown in fig. 1, a map navigation module 101, a Vehicle Control Unit (VCU) 102, a Battery Management module (BMS) 103, and a cabin module 104 are installed in the new energy Vehicle.

The vehicle control module 102 is used to control the vehicle powertrain. For example, the operation of various components (e.g., a battery, a transmission, a motor, an engine, etc.) of the automobile is controlled in a coordinated manner, so that the vehicle can operate stably.

The battery management module 103 is used for monitoring the state of the battery system and performing intelligent management and maintenance on the battery system. For example, battery operating state information is acquired (for example, charging and discharging power of the battery is calculated according to the ambient temperature and the battery state), the battery operating state information is output, and necessary information is provided for the execution device to ensure that the battery is in a safe operating interval.

The cabin module 104 is used for providing an interactive interface for interaction with a user (driver), and realizing operations such as displaying navigation road condition information, displaying vehicle electric quantity, fault detection and vehicle body control based on an intelligent network. The cabin module 104 contains an In-Vehicle information system (IVI), which is an information processing system formed based on a Vehicle bus system and internet services. The IVI coordinates and controls the whole vehicle-mounted information equipment through a special vehicle-mounted processor and an operating system.

Fig. 2 is a flowchart of a new energy vehicle charging method according to an embodiment of the application.

The map navigation module 101, the vehicle control module 102, the battery management module 103 and the cabin module 104 shown in fig. 1 execute the following process shown in fig. 2 to determine whether the new energy automobile needs to be charged during the current journey.

S201, the map navigation module 101 obtains destination information input by the user, where the destination information is used to indicate a destination position of the current trip.

S202, the map navigation module 101 recommends a possible driving route according to the destination information input by the user.

Specifically, the map navigation module 101 identifies destination information input by a user, determines a plurality of possible travel paths from the current position to the destination position according to the current position and the destination position corresponding to the destination information, and outputs the plurality of possible travel paths to the user, so that the user can select one travel path (first travel path) from the plurality of possible travel paths as a subsequent actual travel path.

S203, the map navigation module 101 determines a first driving route selected by the user from the multiple possible driving routes according to the route selection operation of the user.

S204, the map navigation module 101 acquires, based on the first travel path, a required time to reach the destination along the first travel path (first duration), and a remaining travel distance to reach the destination along the first travel path from the current position (length of the first travel path, first travel distance).

S207, the battery management module 103 acquires the current remaining power (first power) of the vehicle.

S208, the battery management module 103 outputs the current remaining power (first power) to the cabin module 104.

S209, the vehicle control module 102 obtains the power consumption of hundreds of kilometers corresponding to the first travel path. The hundred kilometers of power consumption is the electric energy consumed by the electric automobile running for 100 kilometers.

Specifically, in an actual application scenario, power consumption states of vehicles under different road conditions and different vehicle speeds are not completely the same. Therefore, the power consumption of the vehicle in hundred kilometers is different under different driving paths and different driving times.

Therefore, before S209, S205 is also performed.

S205, the map navigation module 101 outputs the first driving range and the first duration to the vehicle control module 102.

In S209, the vehicle control module 102 obtains the power consumption of hundreds of kilometers corresponding to the first driving route based on the first driving range and the first duration.

S210, the vehicle control module 102 outputs the hundred kilometers of power consumption corresponding to the first travel path to the cabin 104.

S206, the map navigation module 101 outputs the first driving range to the cockpit module 104.

S211, the cabin module 104 calculates the power consumption (second power) of the first driving range based on the first driving range and the one hundred kilometers of power consumption corresponding to the first driving path.

At S212, the cabin module 104 determines whether charging is required for traveling on the first travel route based on the power consumption amount (second power amount) of the first travel range and the current remaining power amount (first power amount).

Specifically, when the electric quantity is too low or completely 0, damage may be caused to the battery, and when the electric quantity is too low, driving safety may be affected. Therefore, in one embodiment, the charge threshold TBD (e.g., 10% of the total charge) is preset, and the battery needs to be charged when the battery charge is lower than the charge threshold.

In one implementation manner of S212, if a difference between the current remaining power amount (first power amount) and the power consumption amount (second power amount) of the first driving range is greater than or equal to a power threshold, it is determined that the current trip does not need to be charged;

and if the difference value of the current residual electric quantity (first electric quantity) minus the electric consumption (second electric quantity) of the first driving range is smaller than the electric quantity threshold value, judging that the current travel needs to be charged.

After determining that the current trip requires charging, the cockpit module 104 indicates the location of the charging post for charging during travel along the first travel path.

Fig. 3 is a flowchart of a new energy vehicle power supply method according to an embodiment of the application.

The cabin module 104 shown in fig. 1 performs the following process as shown in fig. 3 to determine the position of the charging post.

S301, the cabin module 104 calculates the number of charges in the first travel path based on the power consumption amount (second power amount) of the first travel range, the current remaining power amount (first power amount), and the power threshold value (TBD).

Specifically, in one embodiment, Q is set ₀ Is the electric quantity (SOC) of the vehicle battery in a full state ₀ May be output by the battery management module 103. The current remaining power amount (first power amount) is set to Q1, and the power consumption amount (second power amount) of the first driving range is set to Q2.

In one implementation of S301, the amount of power available for the vehicle to travel in Q1 is Q1-TBD, since it is necessary to ensure that the amount of power is not below TBD for normal vehicle travel. Then, in order to complete the first driving range, the vehicle needs the lowest charging capacity Q to be charged _C Comprises the following steps:

Q _C = Q2- (Q1-TBD). (formula 1)

Since the vehicle needs to be charged when the electric quantity is TBD, the maximum charge amount of a single charge of the vehicle is Q ₀ -TBD. Therefore, if (Q) ₀ -TBD) is equal to or greater than Q _C Then, the vehicle only needs to be charged 1 time to satisfy the minimum charge capacity of charging. That is, the number of times of charging of the vehicle in the first travel path is 1.

Otherwise, if (Q) ₀ TBD) less than Q _C . It means that the number of times the vehicle is charged in the first travel path must be greater than 1.

Further, it is contemplated that the location of the charging post may not be exactly where the vehicle is at the TBD. Therefore, in one implementation of S301, it is set that the vehicle must be charged in advance before the power level decreases to the TBD, so as to avoid that the vehicle cannot find the charging pile when the power level decreases to the TBD. For example, the vehicle is set to be charged by a first preset charge amount Q3 (e.g., Q3 is 10% (0.1Q) of the total charge amount) ₀ ) Start when the electric quantity is reduced to TBD, and finish charging in a mileage interval when the electric quantity is reduced to TBD.

That is, the remaining capacity when the vehicle is charged is (TBD + Q3) to TBD. When the vehicle is charged, the maximum charge amount is as follows: (Q) ₀ -TBD-Q3)～(Q ₀ -TBD)。

To ensure that the remaining charge of the vehicle does not fall below the TBD, the lower limit of the maximum charge (Q) is taken ₀ -TBD-Q3)。

If (Q) ₀ -TBD-Q3) is equal to or greater than Q _C Then, the vehicle only needs to be charged once and fully charged when (or before) the electric quantity is reduced to the TBD, so that the remaining electric quantity when the vehicle travels to the terminal is ensured to be equal to or greater than the TBD. That is, the number of times of charging of the vehicle in the first travel path is 1.

Otherwise, if (Q) ₀ TBD-Q3) less than Q _C . It means that the number of times the vehicle is charged in the first travel path must be greater than 1.

Further, in the process of charging the vehicle, under the condition that the residual electric quantity of the battery system is large, the charging multiplying power is reduced, and the charging time is greatly prolonged. Therefore, to reduce the total charging time, in one embodiment, the vehicle is charged to the second predetermined charge amount Q4 without charging the vehicle battery to full charge by a single chargeA fully charged state of the cell. The charged electric quantity is Q ₀ -Q4 instead of Q ₀ 。

Therefore, when the vehicle is charged, the maximum charge amount is: (Q) ₀ -TBD-Q3-Q4)～(Q ₀ -TBD-Q4)。

To ensure that the remaining charge of the vehicle does not fall below the TBD, a lower limit (Q) of the maximum charge is taken ₀ -TBD-Q3-Q4)。

If (Q) ₀ -TBD-Q3-Q4) is equal to or greater than Q _C Then, the vehicle only needs to be charged once and fully charged when (or before) the electric quantity is reduced to the TBD, so that the residual electric quantity when the vehicle runs to the terminal can be ensured to be more than or equal to the TBD. That is, the number of times of charging of the vehicle in the first travel path is 1.

Otherwise, if (Q) ₀ -TBD-Q3-Q4) less than Q _C . It means that the number of times the vehicle is charged in the first travel path must be greater than 1.

Specifically, a person skilled in the art may set the values of the first preset electric quantity and the second preset electric quantity according to the actual running requirement of the vehicle. For example, in one embodiment, the first predetermined electrical quantity Q3 is set to 0.1Q ₀ The second predetermined quantity of electricity Q4 is 0.2Q ₀ 。

The lower limit of the maximum charge amount per charge is: q ₀ -TBD-0.1Q ₀ -0.2Q ₀ ＝0.7Q ₀ -TBD。

In one implementation of S301, if 0.7Q ₀ TBD is greater than or equal to Q _C Then, the number of times of charging in the first travel path is determined to be 1.

If 0.7Q ₀ TBD less than Q _C It is determined that charging is required more than 1 time (2 times or more than 2 times) in the first travel path.

S302, the cabin module 104 selects a charging pile position for charging in the first travel path and/or a charging amount for each charging according to the number of times of charging in the first travel path.

Fig. 4 is a flowchart of a new energy vehicle charging method according to an embodiment of the application.

In one implementation of S302, in a case where the number of charging times in the first travel path is 1, the map navigation module 101 and the cabin module 104 shown in fig. 1 execute the following process as shown in fig. 4 to determine the charging pile position for charging in the first travel path and the charging amount at the time of charging.

S401, the cabin module 104 calculates a first mileage interval based on the hundred kilometers of power consumption corresponding to the first driving route, where the first mileage interval is a search interval of the charging pile, and is used to instruct the map navigation module 101 to search for the charging pile for charging in the first mileage interval. The first range section corresponds to a position section when the remaining capacity of the vehicle is reduced to (TBD + Q3) -TBD when the vehicle travels on the first travel route.

Specifically, in S401, the driving range (second driving range) of the vehicle when the vehicle travels along the first driving route from the current position (the position of the starting point of the first driving route) based on Q1 and the remaining capacity of the vehicle decreases to TBD + Q3 is calculated based on the power consumption of hundreds of kilometers corresponding to the first driving route. And the driving range of the vehicle (third driving range) when the residual capacity of the vehicle is reduced to the TBD. The first mileage interval is [ second driving mileage, third driving mileage ].

S402, the cabin module 104 outputs the first mileage interval to the map navigation module 101.

S403, the map navigation module 101 searches for all charging piles within the first mileage interval, and obtains the information of the searched charging piles.

Specifically, the map navigation module 101 obtains charging pile information of all charging piles within a range from a second driving range to a third driving range from a current position (a starting point position of the first driving path) on the first driving path.

Specifically, in an embodiment, the charging pile information includes: charging pile location, charging pile category (e.g., fast charging pile or slow charging pile), charging pile parameters (e.g., rated current, maximum/small voltage, output power of charging pile), etc.

Further, in S403, if the map navigation module 101 does not acquire the charging pile information in the first mileage interval, it indicates that there may be no charging pile in the first mileage interval. The map navigation module 101 feeds back to the cabin module 104 that there is no charging pile. The cabin module 104 calculates a new mileage interval (a second mileage interval), and sends the new mileage interval to the map navigation module 101 to search for the charging pile again, thereby expanding the search range of the charging pile.

The second mileage section corresponds to a position section where the remaining power amount is reduced to (TBD + Q3+ Q5) to (TBD + Q3) when the vehicle travels on the first travel route. Q5 is a preset fifth preset electric quantity. In one embodiment, the fifth predetermined amount of power is 5% (5% SOC) of the total amount of power.

If the map navigation module 101 does not acquire the charging pile information within the second mileage interval, the cockpit module 104 calculates a new mileage interval (third mileage interval) again. The map navigation module 101 and the cabin module 104 use Q5 as a step length for expanding a search range each time, and the search range of the charging pile is continuously expanded until the charging pile is searched.

S404, the map navigation module 101 outputs the searched charging pile type and/or charging pile parameter of the charging pile to the cabin module 104.

S405, the cockpit module 104 selects a charging pile (a first charging pile) for charging on the first travel path based on the charging pile category and/or the charging pile parameter of the charging pile.

Specifically, in an embodiment, the cabin module 104 selects one of the plurality of charging piles whose charging pile category is the fast charging pile as the charging pile (first charging pile) for charging on the first travel path.

In another embodiment, the cabin module 104 selects one of the plurality of charging piles with the highest power as the charging pile (the first charging pile) for charging on the first travel path.

S406, the cabin module 104 outputs the selected charging pile (first charging pile) to the map navigation module 101.

S407, the map navigation module 101 sets the selected charging pile (first charging pile) as a charging point of the first driving path.

In the driving process of the vehicle, the map navigation module 101 outputs a reminding message to remind a driver of charging at a charging point.

Further, in an embodiment, in S404, the map navigation module 101 further outputs the searched charging pile position of the charging pile to the cabin module 104.

After S405, the cabin module 104 also executes S408.

S408, the cabin module 104 calculates a lowest charging capacity Q6 of the vehicle at the first charging pile under the lowest power demand that the vehicle can smoothly travel to the end point of the first travel path (i.e. the vehicle at the first charging pile at least needs to be charged with the charging capacity Q6).

Specifically, in one implementation of S408, Q6 is equal to Q _C 。

Specifically, in another implementation manner of S408, the remaining electric quantity Q7 of the vehicle when the vehicle travels to the first charging pile is calculated according to the charging pile position of the charging pile (first charging pile) used for charging. Or when the vehicle runs to the first charging pile, acquiring the remaining electric quantity Q7 of the vehicle.

And calculating the remaining distance (fourth driving distance) of the vehicle from the first charging pile to the terminal according to the charging pile position of the charging pile (first charging pile) for charging. And calculating the power consumption Q8 corresponding to the fourth driving range based on the hundred kilometers of power consumption corresponding to the first driving path.

Based on formula 1, the lowest charging capacity Q6 of the vehicle in the first charging pile is:

q6= Q8- (Q7-TBD). (formula 2)

And S409, calculating the actual charging capacity Q9 of the vehicle in the first charging pile according to the lowest charging capacity Q6 of the vehicle in the first charging pile.

Specifically, in one implementation of S409, Q9 is equal to Q6.

In another implementation of S409:

q9= Q6+ Q10. (formula 3)

Q10 is a preset sixth preset amount of power. In one embodiment, the sixth predetermined amount of power is 5% (5% SOC) of the total amount of power.

And S410, after the vehicle runs to the first charging pile for charging, when the charging capacity of the vehicle is Q9 (or the residual capacity of the vehicle reaches (Q9 + Q7)), reminding a user that the capacity is enough, and stopping charging.

Specifically, in one implementation of S410, the cabin module 104 may alert the user that the power level is sufficient. In another implementation manner of S410, the reminder may also be given by the mobile phone APP of the user.

In one implementation of S302, in the case that the number of times of charging in the first travel path is greater than 1, the map navigation module 101 and the cabin module 104 shown in fig. 1 execute the following process shown in fig. 5 to determine the charging pile position for charging in the first travel path and the charging amount at the time of charging.

S501, the cockpit module 104 calculates a fourth mileage interval based on the hundred kilometers of power consumption corresponding to the first driving route, where the fourth mileage interval is a search interval of the charging pile, and is used to instruct the map navigation module 101 to search the first charging pile for charging in the first driving route in the fourth mileage interval. Refer to S401.

The fourth mileage interval corresponds to a position interval when the remaining electric quantity is reduced to (third preset electric quantity to fourth preset electric quantity) when the vehicle runs on the first running path; the fourth preset electric quantity is greater than or equal to TBD; the third preset electric quantity is greater than or equal to TBD + Q3.

Specifically, in one implementation, the setting of the fourth mileage interval may adopt the setting of the first mileage interval.

In another implementation, the setting of the fourth mileage interval may adopt other settings. For example, in one embodiment, the fourth mileage interval corresponds to the case where the vehicle travels on the first travel path, the remaining power amount is reduced to 30% ₀ ～20％Q ₀ The position interval of time.

S502, the cockpit module 104 outputs the fourth mileage interval to the map navigation module 101.

And S503, the map navigation module 101 searches all the charging piles in the fourth mileage interval, and acquires the searched charging pile information of the charging piles. (refer to S403)

And S504, the map navigation module 101 outputs the searched charging pile type and/or charging pile parameter of the charging pile to the cabin module 104. (refer to S404)

S505, the cabin module 104 selects a first charging pile (a second charging pile) for charging on the first travel path based on the charging pile type and/or the charging pile parameter of the charging pile. (refer to S405)

S506, the cockpit module 104 outputs the selected charging pile (second charging pile) to the map navigation module 101.

In the driving process of the vehicle, the map navigation module 101 outputs reminding information to remind a driver of charging in the second charging pile.

After S507, when the vehicle travels to the second charging pile for charging, the vehicle charging difference second preset electric quantity Q4 reaches a full-charge state of the vehicle battery. For example, when the vehicle is charged to the remaining capacity of (Q) ₀ -Q4), the cabin module 104 alerts the user to stop charging.

And S508, calculating the number of charging times in a second driving path, wherein the second driving path is a section of the first driving path, the starting point of the second driving path is a second charging pile, and the end point of the second driving path is the end point of the first driving path. Refer to S301.

Specifically, in S508, the power consumption of the second travel path may adopt the power consumption of the first travel path corresponding to the one hundred kilometers, or may recalculate the power consumption of the one hundred kilometers.

The remaining range of the vehicle is the total range of the second travel path. The initial remaining capacity of the vehicle is (Q) ₀ -Q4)。

S509, the cabin module 104 selects a charging pile position for charging in the first travel path and/or a charging amount for each charging according to the number of charging times in the second travel path. Refer to S302.

In S509, a next charging pile is selected according to the selected charging pile until the vehicle can travel to the end point of the first travel path after the selected charging pile is charged.

In another embodiment, after determining that the current trip needs to be charged, S301 may be skipped and S401 to S407 may be directly performed to select a first charging pile (first charging pile).

And S301 is executed after the first charging pile is selected, and S408-S409 are executed under the condition that the charging times in the first driving path are 1, and the charging electric quantity of the first charging pile (the first charging pile) is calculated.
