The electronic device according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), mobile Station (MS), electronic device (TERMINAL DEVICE), etc. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices. The electronic device may also be a server and a gaming peripheral.

Referring to fig. 1, fig. 1 is a schematic diagram of a first power distribution system of a charging pile according to an embodiment of the application. As shown in FIG. 1, the system comprises an A charging module group, a B charging module group, a C charging module group, a D charging module group, an E charging module group, an F charging module group, an A charging gun, a B charging gun, a C charging gun, a D charging gun, an E charging gun, an F charging gun, a direct current bus and a bus bar 1k, a bus bar 2k, a bus bar 3k, a bus bar 4k, a bus bar 5k, a bus bar 6k, a bus bar 7k, a bus bar 8k, a bus bar 9k, a bus bar 10k, a bus bar 11k and a bus bar 12k.

The charging device comprises an A charging module group, a B charging module group, a C charging module group and a C charging module group, wherein the A charging module group corresponds to an A charging gun, and the A charging module group is connected with the A charging gun and defaults to be used by the A charging gun; the B charging module group corresponds to the B charging gun, is connected with the B charging gun and is used by default; the C charging module group corresponds to the C charging gun, is connected with the C charging gun and is used by default; the D charging module group corresponds to the D charging gun, is connected with the D charging gun and is used by default; the E charging module group corresponds to the E charging gun, is connected with the E charging gun and is used by default; the F charging module group corresponds to the F charging gun, is connected with the F charging gun and is used by default. The charging module group A, the charging module group B, the charging module group C, the charging module group D, the charging module group E and the charging module group F are sequentially connected in an annular mode through the bus bar 1k, the bus bar 2k, the bus bar 3k, the bus bar 4k, the bus bar 5k and the bus bar 6k, so that a certain charging module group can be switched to two corresponding charging guns through two bus bars connected with the charging module group to form an annular power distribution mode; for example: the B charging module group can be used for the A charging gun through the bus 1k switching, and the B charging module group can be used for the C charging gun through the bus 2k switching.

However, the current annular power distribution mode has the problem of "breaking", for example: when the B charging gun and the D charging gun are operated, the B charging module group and the D charging module are utilized by the B charging gun and the D charging gun, and when the C charging gun is also used and the required power is larger than the maximum output power of the C charging module group, namely the C charging module group cannot meet the power requirement of the C charging gun, but the B charging module group and the D charging module group are also in a utilization state, and at the moment, the B charging module group and the D charging module group are free to be used, but lack of the bus to be used, so that the resource of the charging module group is wasted, and therefore, additional bus can be introduced on the basis of the current annular power distribution mode, namely the A charging module group, the B charging module group, the C charging module group, the D charging module group, the E charging module group and the F charging module group are respectively connected with the direct current bus through the bus 7k, the bus 8k, the bus 9k, the bus 10k, the bus 11k and the bus 12k, and the annular power distribution mode capable of being overlapped is formed. At the moment, the E charging module group can be allocated to be used for the C charging gun by closing the busbar 9k and the idle busbar 11k to be used.

Fig. 2 is a schematic diagram of a second power distribution system of a charging pile according to an embodiment of the present application, and fig. 2 shows a flexible power distribution manner of the charging pile, where the system includes an H charging module group, an I charging module group, a J charging module group, a K charging module group, an L charging module group, an M charging module group, an H charging gun, an I charging gun, a J charging gun, a K charging gun, an L charging gun, an M charging gun, and a bus 13K-bus 42K. Each charging module group has a special bus-tie switch to any charging gun, for example: the H charging module group is respectively switched to an I charging gun, a J charging gun, a K charging gun, an L charging gun and an M charging gun through the busbar 13K, the busbar 14K, the busbar 15K, the busbar 16K and the busbar 17K. In the flexible power distribution mode, the charging gun is used for 30 bus-bars, and if N groups of modules and N pairs of modules are strong, the number of the bus-bars used in the flexible power distribution mode is as follows: n >2, and the number of bus-bars used in the stackable annular power allocation mode is: and compared with a flexible power distribution mode, the 2N saves the cost of the bus coupler.

In one possible example, the first required total power of the first charging guns in the first charging unit of the target charging stack and the first output total power of the maximum output of the first charging module group can be determined first, the first charging unit includes a plurality of first charging guns, a plurality of first charging module groups corresponding to the plurality of first charging guns and a first direct current bus, the plurality of first charging module groups sequentially pass through a bus ring connection, the plurality of first charging module groups are connected with the first direct current bus through the bus, then when the first required total power is determined to be smaller than or equal to the first output total power, the actual output total power of the first charging module groups in the first charging unit is determined, further when the actual output total power is determined to be smaller than the first required total power, the first target charging gun with the largest required power in the first charging unit is determined, the first target charging module group to be used in the first charging unit is determined, finally, the bus between the target charging module to be used and the first direct current bus is closed, and the bus between the first target charging module to be used and the first direct current bus is closed. Compared with a flexible distribution mode of a bus-tie which is specially switched to each charging gun for each charging module group, the method is beneficial to saving cost, and can allocate a target charging module to be used to a first target charging gun for use when the first required total power is detected to be smaller than or equal to the first output total power and the actual output total power is smaller than the first required total power, so that the utilization rate of the charging module group is improved.

Referring to fig. 3, fig. 3 is a flow chart of a power distribution method of a charging pile according to an embodiment of the application, where the method includes:

In step S301, a first required total power of the first charging gun in the first charging unit of the target charging stack and a first output total power of the maximum output possible by the first charging module group are determined.

The first charging unit comprises a plurality of first charging guns, a plurality of first charging module groups corresponding to the first charging guns and a first direct current bus, wherein the first charging module groups are sequentially connected through a bus in an annular mode, and the first charging module groups are connected with the first direct current bus through the bus.

The first charging module groups are connected with the corresponding first charging guns, and the plurality of first charging module groups are sequentially connected at one time through the bus to form a ring shape.

The target charging pile comprises charging units, each charging unit comprises a plurality of charging guns, a charging module group, a plurality of bus bars and a direct current bus bar, and the maximum power output by different charging module groups is the same or different.

The first total power demand is the sum of the power demands of at least one first charging gun currently operated by the first charging unit, and the first total power output is the sum of the power outputs of all the first charging module groups of the first charging unit.

Step S302, when it is determined that the first required total power is less than or equal to the first output total power, determining an actual output total power of the first charging module group in the first charging unit.

The first demand total power is smaller than or equal to the first output total power, which indicates that the current first charging unit can meet the charging demand of the current charging device, and the current charging device can be a new energy electric automobile.

The actual total output power is the actual total output power of at least one first charging module group currently operated by the first charging unit.

Step S303, when it is determined that the actual total output power is smaller than the first required total power, determining a first target charging gun with the largest required power in the first charging unit, and determining a first target charging module group to be used in the first charging unit.

The actual output total power is smaller than the first required total power, which indicates that the first charging unit has a problem of breakage, and an idle first charging module group is not used, so that the idle first charging module can be allocated through a first direct current bus.

The first target charging gun is any one of a plurality of first charging guns, and the first target charging module group to be used is preferentially allocated to the charging gun with the largest required power in the first charging unit.

The first charging gun corresponding to the first target charging module group to be used is not in use.

Step S304, closing a bus between the first target charging module group to be used and the first dc bus, and closing a bus between the first charging module group of the first target charging gun and the first dc bus.

The method comprises the steps of enabling a target charging module to be used to be adjusted to a first target charging gun for use by closing a bus between the target charging module to be used and a first direct current bus and closing a bus between a first charging module group of a first target charging gun and the first direct current bus, and then, carrying out in-loop charging module group redistribution on the basis of eliminating the target charging module to form optimal power distribution.

In one possible example, after determining the first total power demand of the first charging gun and the first total power output of the maximum output possible by the first charging module group in the first charging unit of the target charging stack, the method may further include the steps of: when the actual output total power is equal to the first demand total power, determining a second demand total power of a second charging gun and a second output total power of a maximum output possible by a second charging module group in a second charging unit of the target charging stack, wherein the second charging unit comprises a plurality of second charging guns, a plurality of second charging module groups corresponding to the plurality of second charging guns and a second direct current bus, the target charging stack comprises a plurality of charging units, and the first charging unit and the second charging unit are any two of the plurality of charging units; when the second required total power is detected to be larger than the second output total power, judging whether the first charging unit has the first target charging module group to be used or not; when the first charging unit is judged to have the first target charging module group to be used, determining a second target charging gun with the largest required power in the second charging unit when the first direct current bus is judged to be not used by the first charging unit; closing a bus between the first target charging module group to be used and the first direct current bus, a bus between the first direct current bus and the second direct current bus, and a bus between a second charging module group corresponding to the second target charging gun and the second direct current bus.

The plurality of second charging module groups are sequentially connected with the second direct current bus through the bus in a ring-shaped mode.

The second total power demand is the sum of the power demands of at least one second charging gun currently operated by the second charging unit, and the second total power output is the sum of the power outputs of all the second charging module groups of the second charging unit.

Wherein, the second total power demand being greater than the second total power output indicates that the second charging unit cannot meet the charging demand of the current charging device; when the first charging unit is judged to have the target charging module to be used and the first direct current bus is not used by the first charging unit, the target charging module to be used can be directly adjusted to be used by the second charging unit, and the adjustment and the use between the charging units can be realized by closing the bus between the first target charging module group to be used and the first direct current bus, the bus between the first direct current bus and the second direct current bus and the bus between the second charging module group corresponding to the second target charging gun and the second direct current bus.

The first target charging module group to be used is preferentially allocated to the charging gun with the largest power required in the second charging unit.

If the first direct current bus and the second direct current bus are directly connected through a bus, closing the bus between the first direct current bus and the second direct current bus refers to closing the bus directly connected between the first direct current bus and the second direct current bus; if the first dc bus and the second dc bus are indirectly connected by a bus, for example: the first direct current bus is directly connected with the target direct current bus through a bus bar, the second direct current bus is directly connected with the target direct current bus through a bus bar, and then the bus bar between the closed first direct current bus and the second direct current bus refers to the bus bar which is directly connected with the target direct current bus by the closed first direct current bus and the bus bar which is directly connected with the target direct current bus by the closed second direct current bus.

It can be seen that, in this example, when detecting that the second charging unit cannot meet the charging requirement of the charging device and that the first charging unit has an idle charging module group, the first target charging module group to be used is closed to be in bus connection with the first direct current bus, and the first direct current bus and the second direct current bus are in bus connection with the second charging module group corresponding to the second target charging gun and the second direct current bus, so as to realize the transfer and use of the charging module group between the charging units, thereby being beneficial to improving the utilization rate of the charging module group.

In one possible example, after the first charging unit is determined to have the first target charging module group to be used, the method may further include the steps of: when the first direct current bus is judged to be used by the first charging unit, determining a target allocation strategy of the first charging unit when the first direct current bus is not used; judging whether the target allocation strategy is better than the current allocation strategy of the first charging unit; if the target allocation strategy is better than the current allocation strategy of the first charging unit, executing the target allocation strategy of the first charging unit, and determining a second target charging module group to be used; closing a bus between the second target charging module group to be used and the first direct current bus, a bus between the first direct current bus and the second direct current bus, and a bus between a second charging module group corresponding to the second target charging gun and the second direct current bus; if the target allocation strategy is judged to be not better than the current allocation strategy, determining the maximum first required power of a single charging gun in the first charging unit and the maximum second required power of the single charging gun in the second charging unit; and if the second required power is larger than the first required power and the second required power is larger than a preset power threshold, executing the target allocation strategy of the first charging unit, and closing the bus between the second target charging module group to be used and the first direct current bus, the bus between the first direct current bus and the second direct current bus and the bus between the second charging module group corresponding to the second target charging gun and the second direct current bus.

When the first direct current bus is judged to be used by the first charging unit, the target charging module to be used cannot be directly transferred to the second charging unit for use at the moment, whether the target charging module to be used is transferred to the second charging unit for use or not is judged, whether the first charging unit has a transfer strategy which is better than the current transfer strategy or not is needed to be judged when the first direct current bus is not used, if the transfer strategy which is better than the current transfer strategy is available, transfer of a charging module group between the first charging unit and the second charging unit is considered, and transfer among the charging units does not influence the inside of the first charging unit to meet the charging requirement of current charging equipment at the moment; if the optimal allocation strategy does not exist, the comparison of the maximum required power of the single charging gun in the first charging unit and the maximum required power of the single charging gun in the second charging unit is considered, and if the maximum required power of the single charging gun in the second charging unit is larger than the maximum required power of the single charging gun in the first charging unit and the maximum required power of the single charging gun in the second charging unit is larger than a preset power threshold, the allocation of the charging module group between the first charging unit and the second charging unit is considered, so that the second charging unit with larger required power is preferentially met.

The preset power threshold may be set manually or by default, which is not limited herein.

The target allocation strategy is an optimal allocation strategy which is determined through prediction when the first charging unit does not use the first direct current bus for allocation.

It can be seen that, in this example, when the first dc bus is used by the first charging unit, two factors including a better allocation policy of the first charging unit and a required power of a single charging gun are considered as whether to allocate between the first charging unit and the second charging unit, which is beneficial to improving the intelligence of allocating the charging module group between the charging units and improving the utilization rate of the charging module group.

In one possible example, in the determining whether the target allocation policy is better than the current allocation policy of the first charging unit, the method may include the steps of: determining a first number of first groups of charging modules used by the target allocation policy and a second number of first groups of charging modules used by the current allocation policy; if the first quantity is larger than or equal to the second quantity, determining that the target allocation strategy is better than the current allocation strategy; and if the first quantity is less than the second quantity, determining that the target allocation strategy is not superior to the current allocation strategy.

Under the condition that the first direct current bus is not used, if the first number of the first charging module group used by the target allocation strategy of the first charging unit is larger than or equal to the second number, the first charging unit can still meet the charging requirement of the current charging equipment under the condition that the first direct current bus is not used, and the target allocation strategy is better than the current allocation strategy.

For example, when the first charging unit includes a charging module group a, a charging module group B, a charging module group C, a charging module group D, a charging module group E, a charging module group F, a charging gun a, a charging gun B, a charging gun C, a charging gun D, a charging gun E, a charging gun F, a first dc bus, a bus 1k, a bus 2k, a bus 3k, a bus 4k, a bus 5k, a bus 6k; the current allocation policy of the first charging unit is that a B charging gun, a C charging gun and a D charging gun respectively use a B charging module group, a C charging module group and a D charging module group, the C charging gun also uses an E charging module group through a first direct current bus, the target allocation policy is that the B charging gun uses the B charging module group, the C charging gun uses the C charging module group and the D charging module group, the D charging module group uses the E charging module group, at the moment, the second number of the first charging module groups used by the current allocation policy is 4, and the first number of the first charging module groups used by the target allocation policy is 4, so that the target allocation policy is used for the current allocation policy.

It can be seen that, in this example, whether the target allocation policy is better than the current allocation policy can be determined based on the number of the first charging module groups used, which is beneficial to improving the intelligence of the charging module group allocation.

In one possible example, after the closing of the bus between the first target charging module group to be used and the first dc bus, the bus between the first dc bus and the second dc bus, and the bus between the second charging module group corresponding to the second target charging gun and the second dc bus, the method may further include the steps of: when detecting that a third target charging gun corresponding to the first target charging module group to be used is used, disconnecting a bus between the first target charging module group to be used and the first direct current bus, a bus between the first direct current bus and the second direct current bus and a bus between the second charging module group corresponding to the second target charging gun and the second direct current bus; and distributing the first target charging module group to be used to the third target charging gun for use.

When the second target charging gun with the largest required power in the second charging unit is detected to stop being used, disconnecting a bus between the first target charging module group to be used and the first direct current bus, a bus between the first direct current bus and the second direct current bus and a bus between the second charging module group corresponding to the second target charging gun and the second direct current bus; and distributing the first target charging module group to be used to the third target charging gun for use. The third target charging gun corresponding to the first target charging module group to be used is detected to be used as the stopping condition of the current inter-charging-unit allocation strategy, and the second target charging gun is stopped to be used as the stopping condition of the current inter-charging-unit allocation strategy.

Optionally, after closing the bus between the second target charging module group to be used and the first dc bus, the bus between the first dc bus and the second dc bus, and the bus between the second charging module group corresponding to the second target charging gun and the second dc bus, the method may further include the following steps: when detecting that a fourth target charging gun corresponding to the second target charging module group to be used is used, disconnecting a bus between the second target charging module group to be used and the first direct current bus, a bus between the first direct current bus and the second direct current bus and a bus between the second charging module group corresponding to the second target charging gun and the second direct current bus; and distributing the second target charging module to be used to the third target charging gun for use.

It can be seen that, in this example, the inter-charging-unit pick setting stop condition can be set, which is advantageous to improve the intelligence of inter-charging-unit charging module group pick.

In one possible example, before determining the first total power demand of the first charging gun and the first total power output of the maximum output possible by the first charging module group in the first charging unit of the target charging stack, the method may include the steps of: determining the target number of a plurality of charging guns in the target charging pile, wherein the plurality of charging guns are correspondingly provided with a plurality of charging module groups; grouping the plurality of charging guns and the plurality of charging module groups according to the target number and the preset number to obtain a plurality of charging groups, wherein each charging group comprises the preset number of charging guns and the preset number of charging module groups; the following operations are performed for each charging group, resulting in a plurality of charging units: the plurality of charging module groups are sequentially connected in an annular mode through a bus, and each charging module group is connected with a direct current bus through the bus to form a charging unit; and sequentially connecting the direct current buses of the charging units in a ring shape through a bus, and connecting the direct current buses of each charging unit with a target direct current bus through the bus.

The preset number is set manually or the default of the system is not limited herein.

When the number of the plurality of charging modules is two, the plurality of charging modules do not need to be annular, the two charging modules are connected through the bus, and when the number of the plurality of charging units is two, the plurality of charging units do not need to be annular, and the direct current buses of the two charging units are connected through the bus.

When the charging guns and the charging module groups in the target charging pile are grouped, the position relationship among the charging guns in the actual target charging pile can be considered, for example: when the target charging stack comprises 12 charging guns and 12 charging module groups, the charging guns can be divided into two 6-gun charging groups or three 4-gun charging groups based on the position relation among the actual charging guns.

After the direct current buses are connected end to form a ring, if the problem of 'fracture' still exists in the ring distribution to cause resource waste, a new direct current 'bus' can be constructed on the framework of the current direct current buses to be distributed and overlapped again, and the direct current bus buses are connected end to end again to form a ring, so that a stackable 'tower' -type structure is formed.

Therefore, in this example, the target charging stack may be split to obtain a plurality of charging units, and a single charging unit may perform internal allocation of the charging module group through the dc bus, and may perform allocation of the charging module group between charging units based on the target dc bus, which is beneficial to improving the utilization rate of the charging module group.

In one possible example, the preset number includes a first preset number, a second preset number, and a third preset number, the first preset number is greater than the second preset number, and the second preset number is greater than the third preset number; in the aspect of grouping the plurality of charging guns and the plurality of charging module groups according to the target number and the preset number to obtain a plurality of charging groups, the method may include the following steps: judging whether the target number is an integer multiple of the first preset number; if the target number is judged to be the integral multiple of the first preset number, dividing the charging guns and the charging module groups into charging groups according to the first preset number, wherein each charging group comprises the charging guns with the first preset number and the charging module groups with the first preset number; if the target number is not the integral multiple of the first preset number, dividing the plurality of charging guns and the plurality of charging module groups into a plurality of charging groups according to the first preset number, the second preset number and the third preset number, wherein each charging group comprises the first preset number, the second preset number, the third preset number or the charging guns and the first preset number, the second preset number or the third preset number of charging module groups.

The first preset number is 6, the second preset number is 5, and the third preset number is 4.

The preset number determining principle is as follows: the number of charging guns of the current charging pile is generally 4 or more, and the mode of allocating the charging module groups to be used through the direct current bus is limited in that only one free charging module group to be used can be allocated, so that the maximum number of charging guns with only one breaking condition needs to be determined, and the number of charging guns in the maximum charging unit is defined asThe number of charging guns in operation is N, when/>The following results were obtained: when n=1, the bus is normally disconnected from other modules without interference, when n=2, the bus is normally disconnected from other modules without interference, when n=3, even if a certain charging gun is limited due to overlarge requirement, the idle charging module group can be disconnected from the direct current bus, and when n=4, the bus is not required to be allocated through the direct current bus, and each charging gun uses the charging module group; when/>The following results were obtained: when n=1, the bus is normally used for dropping and dialing other modules, no interference exists, when n=2, the bus is normally used for dropping and dialing other modules, no interference exists, when n=3, even if a certain charging gun is limited due to overlarge requirement, an idle charging module group can be dropped and dialed through a direct current bus, when n=4, at most, only an idle charging module group is left, the charging module group can be invoked in an annular ring, and also can be invoked through the direct current bus, when n=5, the bus does not need to be allocated and dialed, and each charging gun uses the charging module group; when (when)The following results were obtained: when n=1, the master link normally drops and dials other modules without interference, when n=2, the master link normally drops and dials other modules without interference, when n=3, at the moment, even if a certain charging gun is limited due to overlarge requirement, the idle charging module group can be dropped and dialed through a direct current bus, when n=4, in order to make 2 charging guns interfered at the same time, 3 charging guns need to be staggered (respectively clamp two charging guns) to realize, and when the number of operating guns is 5, the number of the charging guns is inconsistent with the large premise of n=4, so that the situation does not exist, therefore, when n=5, at most one idle charging module group is left, the charging module group can be called in the ring, and when n=6, each charging gun uses its own charging module group; while when/>When n=5, there are 3 charging guns staggered, and at this time, there is a certain probability that two charging guns are limited, and at this time, two direct current buses are needed to realize the process, so/>The first preset number can be set to 6 for the optimal number of charging guns of the charging unit.

In practice, the number of charging guns in the target charging pile is not a multiple of 6, so the second preset number may be set to 5 and the third preset number may be set to 4 to assist in dividing the charging units, for example: when the target charging pile comprises 8 charging guns, the charging units can be divided into 2 charging guns 4, when the target charging pile comprises 9 charging guns, the charging units can be divided into 1 charging gun 4 and 1 charging gun 5, when the target charging pile comprises 10 charging guns, the charging units can be divided into 2 charging guns 5, and when the target charging pile comprises 11 charging guns, the charging units can be divided into 1 charging gun 6 and 1 charging gun 5.

It can be seen that, in this example, the charging gun and the charging module group in the target charging pile may be divided into a plurality of charging groups based on the first preset number, the second preset number and the third preset number, so as to further form a plurality of charging units, thereby realizing maximum utilization of the charging module group resources and being beneficial to improving the utilization rate of the charging module group.

Compared with a flexible distribution mode of a bus-tie which is specially switched to each charging gun for each charging module group, the method is beneficial to saving cost, and can allocate a target charging module to be used to a first target charging gun for use when the first required total power is detected to be smaller than or equal to the first output total power and the actual output total power is smaller than the first required total power, so that the utilization rate of the charging module group is improved.

and if the first quantity is less than the second quantity, determining that the target allocation strategy is not superior to the current allocation strategy.
