Description

Technical Field

[0002] With the rapid development of the electric vehicle market, efficient management and optimized scheduling of charging stations have become the focus of industry attention. Traditional charging stations usually adopt a static power distribution method, which still has deficiencies in power distribution and control. They cannot be flexibly adjusted according to real-time charging needs and grid conditions, resulting in low charging efficiency and uneven resource allocation. For example, when multiple charging guns of a charging pile charge multiple electric vehicles at the same time, often only some of the charging guns can reach their maximum charging power (i.e. full load state), while the remaining charging guns are limited in power, resulting in a reduced charging current, which makes the charging time longer and reduces the user experience.

[0082] Figure 1 A flow chart of a multi-pile, multi-gun, fast-charging, high-power charging control method provided by the present invention is shown.

[0083] like Figure 1 As shown, the present invention discloses a multi-pile multi-gun fast charging high-power charging control method, comprising:

[0084] S102, when the vehicle is connected to the charging gun, determining the newly connected charging gun as the first charging gun;

[0085] S104, obtaining charging request data of the vehicle; the charging request data at least includes remaining power, charging required power and user expected charging duration;

[0086] S106, analyzing the charging request data of the vehicle to determine charging parameters of the first charging gun; the charging parameters include a charging score, a maximum fast charging power, a first fast charging power, and a second fast charging power;

[0087] S108, obtaining the idle power of the charging pile and the charging parameters of the charging gun in the charging state;

[0088] S110, analyzing the charging parameters of the first charging gun, the idle power of the charging pile, and the charging parameters of the charging gun in the charging state, determining whether the first charging gun meets the fast charging condition of the maximum fast charging power, and if so, supplying power to the first charging gun at the maximum fast charging power; if not, adjusting the charging power of the charging gun in the charging state, and supplying power to the first charging gun at the second fast charging power;

[0089] S112, when the first charging gun does not meet the fast charging condition of the second fast charging power, auxiliary power supply is provided through the charging battery cabinet;

[0090] S114, determining whether the charging battery cabinet meets the auxiliary power supply condition. When the charging battery cabinet does not meet the auxiliary power supply condition, adjusting the charging power of the charging gun in the charging state again, and supplying power to the first charging gun according to the first fast charging power;

[0091] S116, monitor the idle power of the charging pile in real time, and adjust the charging power of the charging gun in the charging state according to the idle power of the charging pile.

[0092] According to an embodiment of the present invention, when a vehicle and a charging gun are connected, they are bound to each other, and the charging gun is determined as a first charging gun. The charging score of the first charging gun is calculated based on the charging request data of the bound vehicle, the charging level is determined, and the charging weight of the first charging gun is calculated in combination with the charging parameters of the bound vehicle to determine the maximum fast charging power, the first fast charging power and the second fast charging power of the first charging gun.

[0093] In the process of power allocation for the first charging gun, the idle power of the charging pile and the maximum fast charging power and the second fast charging power of the first charging gun are first analyzed. If the idle power of the charging pile is greater than the maximum fast charging power, the power of the first charging gun is allocated according to the maximum fast charging power; if the idle power of the charging pile is between the maximum fast charging power and the second fast charging power, the power of the first charging gun is allocated according to the second fast charging power; if the idle power of the charging pile is less than the second fast charging power, the maximum fast charging power of one or more charging guns in the charging state is adjusted to the second fast charging power, and the idle power of the charging pile and the first adjusted power generated by the adjustment of each charging gun are accumulated to determine the first accumulated power. The first accumulated power is allocated to the first charging gun, so that the first charging gun can quickly charge the bound vehicle according to the second fast charging power. When the first accumulated power is less than the second fast charging power of the first charging gun, it is determined that the first charging gun does not meet the fast charging condition of the second fast charging power. Determine whether the first charging gun meets the fast charging condition of the first fast charging power. If so, fast charge the bound vehicle according to the first fast charging power; if not, start the charging battery cabinet configured in the charging pile to provide auxiliary power to the first charging gun, so that the first charging gun meets the fast charging condition of the first fast charging power.

[0094] When using a charging gun to fast charge a vehicle, the output power of the charging gun is adjusted in real time according to the battery SoC value of the vehicle, and the vehicle is fast charged by a power gradient change. The battery SoC value of the vehicle can be used to determine the current fast charging stage of the charging gun, and the required power, maximum fast charging power, first fast charging power, and second fast charging power required in the current fast charging stage.

[0095] When starting the charging battery cabinet for auxiliary charging, it is determined whether the remaining maximum output power of the charging battery cabinet is greater than or equal to the first auxiliary power supply power and whether the remaining power of the charging battery cabinet is greater than the power required by the first charging gun in the current fast charging stage, so as to determine whether the charging battery cabinet meets the auxiliary power supply conditions. If satisfied, the charging battery cabinet is started for auxiliary power supply; if not satisfied, the actual fast charging power of one or more charging guns in the charging state is adjusted to the first fast charging power, and power compensation is performed on the first charging gun.

[0096] At the same time, when using the charging pile to charge the vehicle, the idle power of the charging pile is monitored in real time, and the idle power of the charging pile is updated according to the switching power difference generated when the charging gun switches the charging stage, and the idle power of the charging pile is preferentially allocated to the charging gun in the normal charging mode to switch it to the fast charging mode. When there is a charging gun whose actual fast charging power is less than the second fast charging power, the power is allocated to each charging gun in order from large to small according to the charging score, so that the actual fast charging power of the charging gun is adjusted to the corresponding second fast charging power; when the actual fast charging power of all charging guns is greater than or equal to the corresponding second fast charging power, the idle power of the charging pile is allocated to the charging battery cabinet for battery pack charging according to actual needs, or the actual fast charging power of the charging gun is adjusted to the maximum fast charging power.

[0097] According to an embodiment of the present invention, the charging request data of the vehicle is analyzed to determine the charging parameters of the first charging gun; the charging parameters include a charging score, a maximum fast charging power, a first fast charging power, and a second fast charging power, including:

[0098] Calculate a charging score of the first charging gun according to the charging request data;

[0099] Determine a charging level of the first charging gun according to the charging score;

[0100] Determine a first fast charging power range of the first charging gun m according to the charging parameters of the vehicle M;

[0101] Calculate the charging weight corresponding to each charging level according to the first fast charging power interval;

[0102] The minimum fast charging power in the first fast charging power interval is determined as the first fast charging power P of the first charging gun m. 1(m) ;

[0103] The maximum fast charging power of the first fast charging power interval is determined as the maximum fast charging power P of the first charging gun m. max(m) ;

[0104] The maximum fast charging power P in the first fast charging power interval max(m) Multiply it by the corresponding charging weight to determine the second fast charging power P of the first charging gun m 2(m) .

[0105] It should be noted that each data parameter in the charging request data (including at least the remaining power, the charging demand power and the user's expected charging duration) is multiplied by the corresponding influence weight, and the calculation results are accumulated to determine the charging score of the first charging gun. Among them, the influence weight of the data parameter is set by the system, and the value range of the charging score is 0-100. At the same time, the system is divided into multiple charging levels according to the value range of the charging score, and each charging level is set with a corresponding charging weight. For example, the system divides the charging score into 4 charging levels, and the charging score ranges corresponding to each charging level are the first level (0-25), the second level (26-50), the third level (51-75) and the fourth level (76-100).

[0106] The vehicle connected to the first charging gun is determined as vehicle M, and the first fast charging power interval of the first charging gun m is determined according to the fast charging power range, maximum fast charging power and minimum fast charging power calibrated in the charging parameters of vehicle M.

[0107] The calculation formula for the charging weight corresponding to the charging level is:

[0108] ;

[0109] Among them, K is the charging weight corresponding to the charging level, Pk(min) is the minimum fast charging power of vehicle M, Pk(max) is the maximum fast charging power of vehicle M, Qmax is the maximum charging score within the charging score range corresponding to the charging level, and k1 is the correction coefficient set by the system.

[0110] Among them, Pmax(m)≥P2(m)≥P1(m). When any one of the first fast charging power P1(m), the second fast charging power P2(m) and the maximum fast charging power Pmax(m) is greater than the maximum rated output power of the first charging gun m, the corresponding fast charging power is updated based on the maximum rated output power of the first charging gun m.

[0112] like Figure 2 As shown, according to an embodiment of the present invention, according to the charging parameters of the first charging gun, the idle power of the charging pile and the charging parameters of the charging gun in the charging state, it is determined whether the first charging gun meets the fast charging condition of the maximum fast charging power. If so, the first charging gun is powered at the maximum fast charging power. If not, the charging power of the charging gun in the charging state is adjusted, and the first charging gun is powered at the second fast charging power, including:

[0126] It should be noted that the charging pile is equipped with a large-capacity charging battery cabinet to assist the power supply of the power grid so that the charging gun of each charging pile can output high power at the same time.

[0127] If all charging guns in the charging state are adjusted to the second fast charging power or later, if the actual charging power of the first charging gun m does not meet the corresponding second fast charging power P2(m) , then according to the lowest fast charging power standard, that is, the first fast charging power P 1(m) Power is distributed to the first charging gun m.

[0137] When it is determined that the auxiliary power supply condition is met, the first auxiliary power supply power Pb1 , the required power of the first charging gun m in the current fast charging stage, the occupancy and remaining power of the battery packs in the charging battery cabinet, and select one or more battery packs for power supply.

[0138] According to an embodiment of the present invention, when the charging battery cabinet does not meet the auxiliary power supply condition, the charging power of the charging gun in the charging state is adjusted again, and the first charging gun is powered according to the first fast charging power, including:

[0139] When P1≥P 1(m) When the first accumulated power P q1 Allocating power to the first charging gun m;

[0140] When P1<P 1(m) When the second auxiliary power supply power P is determined according to the ratio of the remaining power of the charging battery cabinet to the charging time of the first charging gun m in the current fast charging stage, b2 ;

[0141] The remaining maximum output power of the rechargeable battery cabinet and the second auxiliary power supply power P b2 The minimum value among them is determined as the third auxiliary power supply power P b3 ;

[0142] According to the first fast charging power P of the first charging gun m 1(m) and the third auxiliary power supply power P b3 The power difference determines the first power to be compensated P c1(m) ;

[0143] Calculate the actual charging power P of all charging guns n in the charging state 3(n) And the corresponding first fast charging power P 1(n) The sum of the first difference powers;

[0144] Determine whether the sum of the first difference powers is greater than or equal to the first to-be-compensated power P of the first charging gun m c1(m) ;

[0145] If so, the actual charging power P of one or more charging guns n in the charging state is increased in order from small to large. 3(n) Adjust to the first fast charging power P 1(n) ; Actual charging power P through charging gun n in charging state 3(n) And the corresponding first fast charging power P 1(n) The first difference power is used to compensate the first charging gun m for power; when the actual charging power P of the first charging gun m 3(m) Greater than or equal to the corresponding first fast charging power P 1(m) When , the power compensation ends;

[0146] If not, it is determined that the first charging gun m does not meet the fast charging condition, and the mode is switched to the normal charging mode, and a pop-up window is displayed to remind the user.

[0147] It should be noted that when the charging battery cabinet does not meet the auxiliary power supply conditions, it is first determined that the first adjustment power P of all charging guns n in the charging state is a1(n) The first accumulated power P obtained after accumulation q1 Is it greater than the first fast charging power P of the first charging gun m? 1(m) If so, then the first accumulated power P q1 All are allocated to the first charging gun m for fast charging of the corresponding vehicle M; if not, the remaining power of the charging battery cabinet and the remaining maximum output power of the charging battery cabinet are calculated to ensure that the first charging gun m meets the second fast charging power P in the current fast charging stage. 2(m) The third auxiliary power supply power P b3 , the first fast charging power P of the first charging gun m 1(m) Determine the first power P to be compensated for the first charging gun m c1(m) . While ensuring that the actual charging power of all charging guns n in the charging state is adjusted to the sum of the first difference power of the first fast charging power is greater than or equal to the first to-be-compensated power P of the first charging gun m c1(m) When the actual charging power P of one or more charging guns n in the charging state is increased in order from small to large, 3(n) Adjust to the first fast charging power P 1(n) , the first difference power is used to compensate the first charging gun m, so that the actual charging power P of the first charging gun m is 3(m) Greater than or equal to the corresponding first fast charging power P 1(m) When the sum of the first difference powers is less than the first power to be compensated P of the first charging gun m c1(m) When the first charging gun m is determined to not meet the fast charging condition, it is switched to the normal charging mode, the power of the first charging gun m is allocated according to the normal charging power preset by the system, and the user is reminded of the charging mode through a pop-up window.

[0148] According to an embodiment of the present invention, the idle power of the charging pile is monitored in real time, and the charging power of the charging gun in the charging state is adjusted according to the idle power of the charging pile, including:

[0149] When there is a charging gun n in the charging state and the charging stage is switched, the idle power P0 of the charging pile is updated according to the generated switching power difference;

[0150] Determine whether the idle power P0 of the updated charging pile is greater than or equal to the first fast charging power of the charging gun in the normal charging state;

[0151] If yes, the idle power P0 of the updated charging pile is allocated to the charging gun in the normal charging state, and the charging gun is switched to the fast charging mode;

[0152] If not, the idle power P0 of the updated charging pile is allocated to the charging battery cabinet to charge the battery pack;

[0153] When the sum of the battery pack charging power and the updated idle power P0 of the charging pile is greater than or equal to the first fast charging power of the charging gun under normal charging state, the battery pack charging power and the updated idle power P0 of the charging pile are allocated to the charging gun under normal charging state, and the charging gun is switched to fast charging mode.

[0154] It should be noted that in the fast charging mode, the charging power of the charging pile will gradually decrease as the battery power increases, resulting in a gradient change. Therefore, the system will determine the charging stage according to the battery SoC value of the vehicle. When the battery SoC value of the vehicle meets the power condition of the next charging stage, the charging power of the corresponding charging gun will be reduced to switch the charging stage. When the idle power P0 of the updated charging pile is less than the first fast charging power of the charging gun in the normal charging state, the idle power P0 of the updated charging pile will be preferentially allocated to the charging battery cabinet, and the corresponding battery pack will be selected for charging according to the battery pack usage status and the remaining power in the battery pack. When the sum of the power of the battery pack charging power and the idle power P0 of the updated charging pile is greater than or equal to the first fast charging power of the charging gun in the normal charging state, the charging of the battery pack in the charging battery cabinet is terminated, and the power of the battery pack charging power and the idle power P0 of the updated charging pile is allocated to the charging gun in the normal charging state, and the charging gun is switched to the fast charging mode. At this time, the fast charging power of the charging gun is at least greater than or equal to the corresponding first fast charging power.

[0155] According to an embodiment of the present invention, it also includes:

[0156] When there is no charging gun in the normal charging state, the charging guns whose actual fast charging power is less than the corresponding second fast charging power are sorted in descending order of charging scores, and the power adjustment time interval of each charging gun is compared with the preset time interval in sequence according to the sorting order, and the charging gun with the largest charging score and satisfying that the power adjustment time interval is greater than or equal to the preset time interval is determined as the second charging gun;

[0157] Calculate the power difference between the second fast charging power of the second charging gun and the actual fast charging power to determine a second differential power;

[0158] Determine whether the second difference power is greater than the idle power of the updated charging pile;

[0159] If yes, the idle power of the updated charging pile is allocated to the second charging gun;

[0160] If not, the second difference power is allocated to the second charging gun, and the third difference power is determined according to the power difference between the second difference power and the idle power of the updated charging pile, and the actual fast charging power of the next second charging gun is adjusted by the third difference power;

[0161] When the actual fast charging power of all charging guns meets the corresponding second fast charging power, the idle power of the updated charging pile is allocated to the charging battery cabinet to charge the battery pack;

[0162] When the battery packs in the charging battery cabinet are all occupied or fully charged, the idle power of the updated charging pile is allocated to each charging pile according to the charging score and the power adjustment time interval, so that the actual fast charging power of one or more charging piles meets the maximum fast charging power.

[0163] It should be noted that when there is no charging gun in the normal charging state, that is, when all charging guns in the charging state are in the fast charging mode, the idle power of the updated charging pile is allocated to the charging gun whose actual fast charging power is lower than the corresponding second fast charging power. In each allocation process, the second charging gun with the largest charging score and the power adjustment time interval greater than or equal to the preset time interval is preferentially determined, and the power is preferentially allocated to the second charging gun. After the actual fast charging power of the second charging gun is adjusted to the corresponding second fast charging power, if the charging pile still has idle power, the next second charging gun is determined, and the power of the next second charging gun is adjusted until there is no idle power in the charging pile, or there is no second charging gun whose power adjustment time interval is greater than or equal to the preset time interval, and the actual fast charging power of the charging gun in the charging state is adjusted. If there is idle power in the charging pile at this time, the battery pack in the rechargeable battery cabinet is charged preferentially. Among them, the preset time interval is set by those skilled in the art according to actual needs.

[0164] According to an embodiment of the present invention, it also includes:

[0165] When adjusting the fast charging power of a charging gun in a charging state, the charging guns whose power adjustment time interval is less than a preset time interval are filtered.

[0166] It should be noted that by setting a preset time interval, the harm of unstable charging power to the battery and charging equipment during the fast charging of the vehicle using a charging gun can be avoided. When adjusting the fast charging power of a charging gun in a charging state, the power adjustment time interval is determined based on the current time and the time when the charging gun last adjusted the fast charging power, and the power adjustment time interval is compared with the preset time interval, and the charging guns whose power adjustment time interval is less than the preset time interval are filtered. Among them, the preset time interval is set by those skilled in the art according to actual needs.
