Detailed Description
According to the electric automobile control method, the technical problem that in the prior art, when an electric automobile cannot timely supplement energy, energy consumption is high due to the fact that an automobile body is heavy is solved.
The technical scheme of the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
the control method of the electric automobile comprises the following steps: detecting total residual electric quantity of N power batteries of the electric automobile, wherein N is a positive integer greater than 1; when the total residual electric quantity is smaller than the preset electric quantity, determining whether a charging station exists in a preset distance; and when no charging station exists in the preset distance, determining a target power battery from the N power batteries, and controlling the target power battery to be separated from the electric automobile at the preset moment.
According to the method, the time for searching the charging station is determined according to the total residual capacity of the power batteries, when the charging station cannot be searched within the preset distance, the target power battery is selected from the plurality of power batteries, and the target power battery is abandoned from the electric automobile at the preset time, so that the weight of the automobile body is reduced, when the weight of the automobile body is reduced, the energy consumption of the electric automobile can be reduced, the same electric quantity can further travel, the purpose of prolonging the endurance mileage is achieved, the endurance mileage is prolonged, the probability of obtaining rescue can be improved, and the probability of the electric automobile trapped in the wild is reduced.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The embodiment provides a control method of an electric automobile as shown in fig. 1, which comprises the following steps:
step S11, detecting total residual electric quantity of N power batteries of the electric automobile, wherein N is a positive integer greater than 1;
step S12, when the total residual electric quantity is smaller than the preset electric quantity, determining whether a charging station exists in a preset distance;
and S13, when no charging station exists in the preset distance, determining a target power battery from the N power batteries, and controlling the target power battery to be separated from the electric automobile at the preset moment so as to reduce the weight of the electric automobile.
The number of power cells on one electric vehicle is generally plural (N in this embodiment). And detecting the total residual electric quantity at intervals of preset time in the running state of the electric automobile. The preset time can be determined according to specific situations.
For example, when the total remaining power is equal to or greater than a preset power (the preset power may be 40%, which may be specifically determined according to the actual situation), the preset time may be 10 minutes, that is, every 10 minutes. When the total remaining power is less than the preset power, the preset time may be 3 minutes, i.e., every 3 minutes.
When the total remaining power is greater than or equal to the preset power, it means that the power of the N power batteries is sufficient. When the total remaining power is smaller than the preset power, the power needs to be supplemented in time, and at this time, whether a charging station exists in the preset distance can be determined. The preset distance is the distance that the electric automobile can reach by taking the current residual electric quantity as energy.
When a charging station is present within a preset distance, navigation may be initiated and energy replenishment may be performed to the charging station. When no charging station exists within the preset distance, in order to prolong the endurance mileage on the basis of the current residual electric quantity, the energy consumption can be reduced by reducing the weight of the electric vehicle. The embodiment reduces the weight of the battery car by dropping the power battery.
Specifically, a target power battery is determined from N power batteries, and the target power battery is controlled to fall off from the electric automobile at a preset time. The number of the target power cells may be one or a plurality of the target power cells.
Determining a target power cell from the N power cells, comprising:
step S21, detecting the sub-residual capacity of each power battery in the N power batteries;
step S22, determining estimated driving mileage corresponding to a plurality of power battery packs in N power batteries according to the sub-residual capacity of each power battery;
step S23, determining M power batteries from N power batteries according to the estimated driving mileage and the received shedding number information corresponding to each power battery group in the plurality of power battery groups, wherein the M power batteries are used as target power batteries, and M is a positive integer smaller than N.
The sub-remaining power of each of the N power cells is detected, and different power cells are combined (note that, in this embodiment, the combination may be made up of a single power cell), so that different estimated driving ranges may be obtained.
For example, when the number of the power batteries is 3, the 3 power batteries are respectively marked as a 1# power battery, a 2# power battery and a 3# power battery, the sub-residual electric quantity is respectively 40%, 30% and 38%, and the corresponding driving mileage is respectively 60Km, 48Km and 56Km, then the following various combinations and estimated driving distances thereof can be obtained:
1# power cell: 60Km;
2# power battery: 48Km;
3# power battery: 56Km;
a # 1 power battery and a # 2 power battery: 108Km (60 Km+48 Km);
1# power cell and 3# power cell: 116Km (60 Km+56 Km);
2# power battery and 3# power battery: 104Km (48 Km+56 Km).
According to different estimated driving mileage, M power batteries needing to be shed can be determined as target power batteries, and certainly, the estimated driving mileage can be displayed on an interface so that a driver can select the M power batteries needing to be shed by himself. M power cells are selected as target power cells from N power cells, and when N is 3, then M may be 1 or 2.
The method mainly determines the target power battery needing to fall off according to the estimated driving mileage, and can also determine the target power battery needing to fall off according to the installation position of the power battery on the electric automobile, and the method comprises the following steps of:
step S31, determining the performance requirement of the electric automobile passing through the current road condition according to the road condition characteristics of the electric automobile;
and S32, determining M power batteries from the N power batteries according to the performance requirements and the distribution positions of the N power batteries on the electric vehicle.
The road condition characteristics may be wading road section characteristics, climbing road section characteristics, downhill road section characteristics, flatter road section characteristics, etc. The performance requirements of electric vehicles are different according to different road condition characteristics. For example, wading road section characteristics, climbing road section characteristics, downhill road section characteristics require improving the longitudinal throughput capability and off-road capability of the whole vehicle leaving the slope section, approaching the slope section, while flatter road section characteristics require improving the steering stability of the whole vehicle.
Therefore, the performance requirements of the vehicle can be determined according to the road condition characteristics, the weight adjustment of each position (mainly the front, middle and rear positions of the vehicle body) of the vehicle body is determined according to the performance requirements, namely, the target power battery which needs to fall off is determined according to the distribution positions of the power batteries on the electric vehicle.
As shown in fig. 2, a schematic diagram of modes after 3 power batteries are discarded from different power batteries, and mode 1 is a mode of discarding 2# power battery and 3# power battery and reserving 1# power battery; mode 2 is a mode in which the 1# power battery and the 3# power battery are discarded, and the 2# power battery is reserved; mode 3 is a mode in which the 1# power battery and the 2# power battery are discarded, and the 3# power battery is reserved; mode 4 is a mode of discarding the 3# power battery, reserving the 1# power battery and the 2# power battery; mode 5 is a mode in which the 2# power battery is discarded, and the 1# power battery and the 3# power battery are reserved; mode 6 is a mode in which the # 1 power battery is discarded, and the # 2 power battery and the # 3 power battery are reserved.
Wherein, two power batteries are reserved in the mode 5, so that the axle load is balanced, and the operation stability of the whole vehicle is facilitated; and the mode 4 and the mode 6 respectively improve the longitudinal passing capacity and the off-road capacity of the vehicle approaching severe road conditions. The mode 1 and the mode 3 can greatly improve the longitudinal passing capacity and the off-road capacity of the whole vehicle approaching to severe working conditions; mode 2 is more conducive to vehicle handling stability.
When the longitudinal passing capability and the cross-country capability of the whole vehicle leaving the slope section and approaching the slope section are required to be improved, the vehicle can be selected from the mode 1, the mode 3, the mode 4 and the mode 6, and when the steering stability of the whole vehicle is required to be improved, the vehicle can be selected from the mode 2 and the mode 5.
In summary, according to the embodiment, the time of searching for the charging station is determined according to the total remaining power of the power batteries, when the charging station cannot be searched within the preset distance, the target power battery is selected from the plurality of power batteries, and the target power battery is discarded from the electric vehicle at the preset time, so that the weight of the vehicle body is reduced, when the weight of the vehicle body is reduced, the energy consumption of the electric vehicle can be reduced, the same power can be driven farther, the purpose of prolonging the endurance mileage is achieved, the endurance mileage is prolonged, the probability of obtaining rescue can be improved, and the probability of the electric vehicle being trapped in the wild is reduced. When the target power battery is selected, the weight configuration of the whole electric automobile can be changed by combining the performance requirements corresponding to the road conditions of the electric automobile, so that the efficiency of the electric automobile passing through the current road conditions is higher.
The electric automobile provided in this embodiment can drive in the cross-country environment, in cross-country road conditions, and the ground is rugged, and power battery installs in electric automobile bottom position, and the easy emergence is knocked into the head, in order to promote electric automobile's cross-country performance, also in order to protect power battery itself, can give priority to the power battery that easily touches the bottom.
Specifically, determining a target power cell from the N power cells includes:
step S41, detecting the collision times of each power battery of the N power batteries;
in step S42, the power battery with the number of collisions exceeding the preset number is used as the target power battery.
Detecting the collision times of each power battery in the N power batteries, and taking the power batteries exceeding the preset times as target power batteries which can fall off.
As shown in fig. 3, the point where the collision frequently occurs is marked, it can be seen that the collision is easy to occur is the 1# power battery, and the 1# power battery can be discarded, when the 1# power battery is discarded, the 2# power battery is easy to collide, and the 2# power battery is discarded, and after the discarding, the installation positions of the 1# power battery and the 2# power battery are empty, so that the corresponding space on the collision point is enlarged, and the vehicle bottom is not easy to collide.
After determining the target power battery from the N power batteries, before controlling the target power battery to be disconnected from the electric vehicle at a preset time, the method further includes:
step S51, controlling a target power battery to supply power for the electric automobile;
in step S52, when the residual electric quantity of the target power battery is lower than the preset threshold, the target power battery is controlled to be disconnected from the electric vehicle at the preset moment.
After the target power battery is determined, the residual electric quantity in the target power battery is required to be exhausted (the exhaustion means that the residual electric quantity of the target power battery is lower than a preset threshold value, the preset threshold value can be set according to specific conditions), and then the target power battery is dropped off, so that all the residual electric quantity is fully utilized, and the driving mileage of the electric automobile is prolonged.
After the control target power battery is disconnected from the electric vehicle at a preset time, the method further comprises:
step S61, a target position of the target power battery falling off is obtained, and the target position is stored.
The power battery is high in manufacturing cost, and in order to recycle the power battery, the falling position of the target power battery can be recorded, so that the power battery can be conveniently used for later-stage itinerant. A GPS tracker may also be mounted on the power cell to determine the location of the target power cell.
The embodiment can be applied to electric vehicles running off-road conditions, and when the residual electric quantity of the power batteries is insufficient and the charging stations and the power exchanging stations cannot be searched and connected, the falling of the power batteries with different numbers can be controlled, so that the weight of the whole vehicle is reduced, and the driving mileage is improved; meanwhile, according to the driving road condition and the installation position of the power battery, the power battery at the corresponding position is designated to fall off, so that the operability, the geometric trafficability and the wild-type performance of the whole vehicle are considered.
In addition, when the power battery is used as a part assembly with the minimum ground clearance of a vehicle and faces severe road conditions (such as crossing over an extremely obstacle convex hull as shown in fig. 4), the battery is extremely easy to support and collide, so that the battery is damaged and leaked, and the safety crisis is brought. Under the condition of special requirements on trafficability, the power batteries at different positions in the power battery can be controlled to fall off through a strategy, so that the longitudinal trafficability and the wild-crossing property of the vehicle are improved, and the escape is realized.
As shown in fig. 5, a flow chart of battery falling off during running of an electric vehicle with 3 power batteries (the total number of power batteries is 3, as shown in fig. 2).
When the SOC Of the battery is less than 30% and below, displaying the remaining SOC (State Of Charge, also called the remaining Charge) on the screen in real time, wherein the ratio Of the remaining dischargeable Charge after the battery is used for a period Of time or is left unused for a long time to the Charge Of the battery in a fully charged State is represented by a common percentage.
The nearby search for a battery/charging station, if any, the navigation goes. If not, judging whether the power battery needs to be dropped off in an emergency, if not, keeping running, and if so, displaying the estimated range values of the power batteries with different quantities.
If 1 power battery is selected to be disconnected, it is determined whether the passing performance is preferentially ensured or the handling performance is preferentially ensured, if the passing performance is preferentially ensured, mode 5 (shown in fig. 2) is selected, if the passing performance is preferentially ensured, mode 6 (shown in fig. 2) is selected, and if both the passing performance and the handling performance are preferentially ensured, mode 4 (shown in fig. 2) is selected.
If 2 power batteries are selected to be disconnected, it is determined whether the passing performance is preferentially ensured or the handling performance is preferentially ensured, if the passing performance is preferentially ensured, mode 1 (shown in fig. 2) is selected, if the passing performance is preferentially ensured, mode 2 (shown in fig. 2) is selected, and if both the passing performance and the handling performance are preferentially ensured, mode 3 (shown in fig. 2) is selected.
After the power battery needing to be shed is determined, the power battery needing to be shed is preferentially used through battery SOC control measurement, the change of the power is monitored at all times, after the power consumption of the power battery needing to be shed is completed, the power battery is shed, and then the repeated utilization rate of the power battery can be improved through GPS (Global positioning System) tour of the power battery.
