Along with the increasing popularization of new energy vehicles, the number of charging piles is also gradually increased, generally speaking, a power distribution system in an area where a charging pile is built has a capacity load upper limit, and in order to fully use a charging gun on the premise of ensuring the safety of a power grid, power regulation needs to be carried out on the existing charging pile, which is called as ordered control in the industry.

Various control methods are provided in the field of charging piles, and the comprehensive regulation and control are performed by combining hardware, and the corresponding algorithm optimization is performed by weighting; for example, the intelligent orderly charging and vehicle scheduling management system acquires relevant information of power grid enterprise management and control charging through a GIS map of the vehicle scheduling management system, and helps the power grid enterprise balance loads of various regions in order to find a nearest and idle charging pile in the shortest time. In the invention, by combining the load of the charger and the capacity information of the transmission power grid, and adopting the monitoring of a circulating program and the dynamic adjustment of a circuit, the whole charging process can be ensured to be carried out safely and stably.

The method comprises the steps of putting the basis of regulation and control on power information, taking the number of charging guns as a trigger condition of regulation and control, reducing the running power of the currently running charging guns according to the running state, avoiding the situation that the current power of the currently running charging guns is not matched with the running state of the currently running charging guns, causing the waste of configured resources, distributing the reduced power to target charging guns needing to be accessed, realizing reasonable utilization and distribution of resources under the condition of guaranteeing the safety of a power grid, and realizing the ordered and reasonable control of charging of the new energy automobile.

Referring to fig. 2, based on the hardware device of the foregoing embodiment, an embodiment of the present application provides a new energy vehicle charging control method, including the following steps:

s10: and after receiving a starting signal of the target charging gun, acquiring the number of the currently running charging guns.

In the specific implementation process, the target charging gun is a charging gun which is used by a user and needs to be charged, and the starting signal of the target charging gun can be a charging request of the user, namely the request that a vehicle to be charged needs to be charged by using the charging gun when the vehicle to be charged is positioned near an idle charging pile in a charging station, or a signal that the vehicle is parked is detected at an idle charging position; there are various manners of obtaining the required charging operation, such as completing the docking between the induction charging gun and the charging port of the vehicle as the required charging operation, or performing the required charging operation on an operation screen of the charging station. And receiving a starting signal of the target charging gun, and acquiring the number of the charging guns which are currently running, namely the charging guns which are connected with the automobile and are being charged.

S20: judging whether the number exceeds the limit number or not according to the number of the charging guns which are currently operated; wherein the limited number is the number of charging guns that can be fully operated under the charging station electrical maximum load limit.

In the implementation process, a safe limit number is determined by considering the actual situation and under the maximum power load limit of the charging station, and the charging gun which runs beyond the limit number may have potential safety hazards and is not allowed, for example: the maximum number of charging guns operating at the rated power in a safe situation is determined as a limiting number, and since the rated power is the maximum power it can output, it is possible to ensure completely that the grid load is not exceeded in any way during operation within this limiting number. In the case of greater safety, it is also possible to slightly reduce the number of full runs as a limiting number, for example, to calculate the number of charging guns that can be fully run under the maximum load limit of the power as 100, which is obviously a theoretical data, and to avoid the risk completely, the number of 99 or 98 can be used as the limiting number.

S30: and if the number exceeds the limit number, acquiring the running state of the currently running charging gun.

In the specific implementation process, obviously, when the limited number is not exceeded, the target charging gun can be directly connected and operated at any power value within the allowable range, so the embodiment mainly performs regulation and control when the limited number is exceeded. Under the healthy charging mode, the whole charging process can be divided into three operation states of quick charging, continuous charging and trickle charging, firstly, the battery is quickly charged to be close to a saturated state under the quick charging, then, the charging current is gradually reduced under the continuous charging to ensure that the battery is fully charged, and finally, the trickle charging is small-current charging to make up the self-discharge loss of the battery after the battery is fully charged, electrons are enabled to keep flowing, and the service life of the electrons is prolonged.

S40: and reducing the running power of the currently running charging gun according to the running state.

In the specific implementation process, because the charging needs to enter the trickle charging state in most practical situations, and the charging gun still keeps the mode of quick charging or continuous charging, the application mainly considers reducing the power of the charging gun needing the charging, specifically, reducing the operating power of the currently operating charging gun according to the operating state, and the method comprises the following steps:

In order to realize reasonable and accurate regulation and control and avoid reduction of insufficient blending or excessive blending, the method limitsThe power cut by each charging gun is not less than the minimum limit power number and not more than the difference between the rated power and the minimum limit power number, which can be expressed as P _Small ≤P _{Cutting off} ≤(P _{Forehead (forehead)} -P _Small ). The charging gun can be judged in such a way that when the charging gun is used specifically, the adjustable peak power number can be set in advance, the power number plus the reduced power number is equal to the rated power, and when the output power of the fully operated charging gun is continuously lower than the adjustable peak power number within a period of time, the charging gun can be considered to be in a trickle charging operation state. In other embodiments, the charging gun can be continuously charged according to the running state of the charging gun, the power of the charging gun is slightly reduced, and the reduced value is smaller than the power reduced by the trickle charge; and for the charging gun in the fast charging state, because the charging gun is not close to the saturation state, the original power charging is required to be kept continuously, and then zero power reduction is carried out on the charging gun.

S50: and distributing power to the target charging guns according to the reduced running power and the number of the target charging guns so as to charge the new energy automobile.

In the specific implementation process, the target charging gun is a charging gun which is used by charging according to the requirement of a user, the power is distributed according to the reduced power number and the number of the target charging guns, the ordered control of charging is completed, and the following regulation and control modes are provided according to the number, specifically:

according to the operating power who cuts down and the quantity of target rifle that charges, to the target rifle distribution power that charges to charge new energy automobile, include:

extracting adjustment power from the reduced running power according to the number of the target charging guns being 1; the adjusting power is obtained according to the maximum power limit value of the charging station, the full-power running quantity of the charging gun and the rated power of the charging gun;

In the specific implementation process, when the number of the target charging guns is one, the problem of multi-gun distribution does not exist, and the target charging guns can directly pass throughDistribution is carried out under the limitation of the maximum power limit of the charging station, and the charging gun distribution is obtained (P) _max -x*P _{Forehead (forehead)} ) Power of kW, i.e. regulated power, wherein P _max Is the maximum limit of the power of the charging station, x is the limit number.

In one embodiment, allocating power to a target charging gun to charge a new energy vehicle according to the reduced operating power and the number of the target charging guns includes:

In the specific implementation process, in the case of multi-gun distribution, in order to achieve reasonable regulation and control, the same power is distributed to each target charging gun, namely the power distributed to each target charging gun is ((P) _max -x*P _{Forehead (D)} ) N) kW, where n is the number of all charging guns remaining available, after sharing, to distribute to the target charging gun with one share of power.

In the embodiment, the basis of regulation and control is put on power information, the state of the charging station is monitored in real time, judgment can be started immediately after a charging signal is obtained, the number of charging guns is used as a trigger condition of regulation and control, the operating power of the charging gun currently running is reduced according to the operating state, the situation that the current power of the charging gun currently running is not matched with the operating state of the charging gun currently running is avoided, waste of configuration resources is caused, the reduced power is allocated to a target charging gun needing to be accessed, reasonable utilization and distribution of resources are realized under the condition of guaranteeing the safety of a power grid, the requirement on modification of hardware equipment is avoided, the cost is higher, reasonable distribution of power is directly realized according to the number, the load safety of the power grid can be met, and the charging of a new energy automobile can be controlled orderly and reasonably.

In one embodiment, before the summed power is divided equally and distributed to each target charging gun respectively to charge the new energy automobile, the new energy automobile charging control method further includes:

and reserving the lowest power of a charging gun in the summed powers to obtain the power to be distributed.

In a specific implementation process, after a user initiates a request, a terminal or a platform issues an instruction to a charging gun to receive the request for 10-15 seconds, in order to ensure that at least one available charging gun exists in the period, avoid the condition that the charging gun cannot be used in a neutral period and improve the effect of charging control, a part of power needs to be reserved to meet the minimum limit power number of one charging gun, and therefore, the power allocated to each target charging gun is ((P) power allocated to each target charging gun _max -x*P _{Forehead (D)} )-P _Small ) N kilowatts, the power to be distributed, i.e. the power after the reserved part is subtracted from the sum of the reduced power.

Based on the steps, the summed power is divided equally and distributed to each target charging gun respectively so as to charge the new energy automobile, and the method comprises the following steps:

In one embodiment, before determining whether the number of charging guns currently running exceeds the limit number according to the number of the charging guns currently running, the new energy vehicle charging control method further includes:

In the specific implementation process, the limited quantity is determined in advance by using each power information, and the quantity is determined by matching with the current states of different charging guns for reasonable distribution, wherein the current states of the charging guns comprise running states and non-running states, the running states are charging states, and the non-running states are charging guns which are not charged.

In one embodiment, obtaining the limit amount according to a power maximum limit of the charging station, a current state of the charging gun, and a rated power of the charging gun includes:

In the specific implementation process, based on the description of the operating state and the non-operating state in the foregoing embodiment, the present embodiment proposes a means for specifically determining the limited number, in the national standard requirement, the minimum duty ratio output by the ac charging gun corresponds to the current being 6a, the power corresponding to the 220v voltage being 1.32kW, the power limit of the platform to the single gun is 1.32kW, and assuming that the rated power of the gun is 7kW, the minimum limit multiple of the real-time power delivered by the platform is 1.32/7=18.86%, which is 20% in this embodiment, because P is P _{Forehead (forehead)} =7kW, minimum limit power number P _Small ＝1.4kW。

Charging station according to maximum power limit P _max And (4) operating, wherein the number of the charging guns in full operation is x, the number of the guns operating according to the minimum value of 1.4kW is y, and the rated power of the alternating current charging gun is P _{Forehead (forehead)} The following conditions need to be satisfied:

in the formula, x and y cannot be negative numbers, the charging strategy is set in advance as shown in figure 4, and the station maximum limit value P is manually input in an operation interface of the charging strategy _max Single AC charging gun P _{Forehead (forehead)} And after the number N of the alternating current charging guns of the station, obtaining the maximum limit value P of the charging station through the linear equation of two elements _max The number x of charging guns in full operation (rounded down) and the number y of guns operating at a minimum of 1.4kW (rounded up) during operation. In the case of a charging strategy, it is preferred,including the name of the ordered charging strategy, the maximum power limit value P _max (kW unit, integer input, minimum 7), AC charging gun rated power P _{Forehead (forehead)} (unit kW, integer input, minimum 7), number of AC guns in station N (unit, integer input, minimum 1), percentage of ordered power limits 20% (manually settable integers no less than 20 and no greater than 100), number of peak power adjustable P _{Regulating device} (unit kW, input integer, minimum 1, maximum not more than P _{Forehead (D)} For example: p is _{Regulating device} =3 kW), the full gun can cut power (P) _{Cutting off} ＝P _{Forehead (forehead)} -P _{Regulating device} Such as P _{Regulating device} =3kW, then P _{Cutting away} =4 kW), wherein the full gun is a charging gun operating at rated power. The output power of the continuous ten-minute charging gun is less than P _{Regulating device} Then the gun is put in accordance with P _{Cutting away} Power regulation is performed.

Since the minimum limiting multiple in the embodiment of the application is 20 percent, namely (P) _max -n*P _{Forehead (forehead)} )≥0.2*P _{Forehead (forehead)} Therefore, by the reverse thrust, the total number of charging guns of the charging station is greater than (P) _max -0.2*P _{Forehead (forehead)} )/P _{Forehead (forehead)} In time, the charging control method can be executed and obtain a good effect. When the new energy automobile charging control method provided by the embodiment of the application is executed, corresponding information can be generated and fed back to a user in each step stage, if the number is judged to exceed the limit number, information needing to adjust power is generated and fed back to the user in use, and if the redundant electric quantity is sufficient, the charging gun with the reduced power can recover full-load operation, and the information is generated and fed back to the user. Due to the fact that the using condition of the charging pile is complex, the number of the operating charging guns can be changed greatly in a short time, the method steps provided by the application can be periodically circulated in the background, the latest number of the operating charging guns can be obtained in time, and real-time ordered regulation and control are achieved. In the business scenario, the following will be further explained with reference to the logic diagram of fig. 5:

firstly, charging station operators manually input the total power capacity of the station at the background, namely the maximum power which can be reached by the station under the maximum power load, and can immediately obtain the number of charging guns which can run at full capacity under the condition, namely the limited number;

secondly, after receiving a starting signal of a target charging gun, according to the total operating power of the current station, the number P of charging guns operating according to the total power = the current _{Forehead (forehead)} Obtaining the number of the charging guns which are currently operated;

then, whether the number of the charging guns currently running exceeds the limit number is judged, so that whether power reduction and allocation is needed or not can be known, namely whether power regulation control is started or not in the attached drawing 5;

if the current value does not exceed the preset value, the platform does not start a power limiting instruction for the newly started charging gun, continues to monitor the quantity in real time, and waits for the next judgment period;

if the current charging gun exceeds the target charging gun value, starting power regulation control, issuing a power control command as shown in fig. 5, obtaining the running state of the currently running charging gun according to the method provided by the embodiment of the application to determine which part of the charging gun needs to be subjected to power reduction, further performing power reduction on the charging gun in the trickle state, and distributing according to the number of the target charging guns to charge the new energy automobile; the user can be synchronously informed that the power limitation is required, and the data is refreshed every thirty seconds to realize real-time control;

finally, the number of the charging guns in operation is obtained in the cycle judging period, and whether the power regulation limitation needs to be removed or not is determined, namely whether the number of the charging guns in operation currently exceeds the limited number or not is obtained in real time; if the quantity still exceeds the limit, the power limit allocation state is continuously kept to operate; if other users finish charging and leave, so that the number of the operating charging guns is reduced to be lower than the limited number, the power regulation limitation is removed, and meanwhile, the power limitation of the target charging gun and the operating charging gun is removed according to the limiting sequence; synchronously informing the user that the power limit is removed, restoring the power to full load, and refreshing the data every thirty seconds to realize the implementation control.
