By controlling the disconnection of the series contactor, the lower charging power requirement can also be met.
In addition, the parallel contactor is adopted to connect the power output units on the plurality of annular charging modules in parallel, and the control unit controls the parallel output of the power output units by coordinately controlling the on and off of the parallel contactor, so that the power output of an external power supply is increased to adapt to the increasing charging power requirement. The embodiment can achieve the effect of increasing the output power without additionally arranging a charging system.
Based on the annular charging system provided in the above embodiment, the embodiment of the present invention further provides a charging control method, which can be applied to the annular charging system shown in fig. 2, fig. 3, or fig. 4. The method is used for controlling power sharing among different annular charging modules when a charging gun of any one annular charging module of the annular charging system is connected with an external power supply, and further charging control is performed.
Specifically, as shown in fig. 5, when the external power receiving source is connected to the charging gun of any one of the annular charging modules, the annular charging module is a main annular charging module, and the control unit of the main annular charging module is configured to implement the following method steps:
s101: and acquiring the working states of the power output units on the other annular charging modules except the main annular charging module.
In order to realize power sharing among different annular charging modules, the working states of the power output units of the different annular charging modules need to be known. When the power output unit is outputting power, namely when the power output unit is occupied by the charging gun, the power output unit is in a working state, and when the power output unit is not outputting power, namely when the power output unit is not occupied by the charging gun, the power output unit is in a standby state.
S102: and determining a target power output unit according to the working states of the rest annular charging modules.
The target power output unit is a power output unit which can be used for power output in the rest annular charging modules. The target power output unit is a power output unit in a standby state; the target output unit can be one or a plurality of target output units, and needs to be determined according to actual conditions, such as the power requirement of an external power supply and/or the requirement of the main annular charging module. The main purpose of this step is to find a power output unit that can be used for power sharing.
S103: and sending power sharing requests to the control units of the other annular charging modules, and controlling the main annular charging module to carry out power output when the control units of the other annular charging modules respond to the power sharing requests, control the parallel contact to be closed and control the specified target power output unit to carry out power output.
After the power output unit capable of providing power is found in S102, the main annular charging module is required to provide a power sharing request to the annular charging module capable of providing power, and when a response power sharing request of the annular charging module capable of providing power is obtained, the corresponding parallel contact is controlled to be closed, and the main annular charging module receives the power output of the target power output unit, so as to implement power sharing between different sub annular charging modules. It should be noted that the closing and opening of the parallel contactor are controlled by coordination between the control units of the different ring charging modules, but in the embodiment of the present invention, it is preferable to control the control unit of the ring charging module receiving the power sharing request. In addition, after the target power output unit outputs power, the power output unit on the main annular charging module also outputs power, so that power output superposition is realized, and the power requirement of an external power supply is met.
In the embodiment, the working states of the power output units on the other annular charging modules are determined, and the target power output unit which can be used for power sharing is determined from the working states, so that the corresponding parallel contact is controlled to be closed, the target power output unit outputs power, and the power output units on the main annular charging module output power simultaneously, so that the output power superposition of the annular charging system is realized, and the requirement of an external power receiver on the charging power is met without improving the interior of the power output unit.
Specifically, referring to the interaction process of fig. 5, before the other ring charging modules respectively share the request, the control unit of the main ring charging module is further configured to:
s201: and judging whether the power surplus of the power output unit of the main annular charging module meets the power requirement of an external power supply.
The power demand refers to a charging power demand. In this step, the remaining power of the power output unit of the main ring charging module is determined to determine whether power sharing is required. Only when the power requirement of an external power supply cannot be met, the annular charging system can send out a power sharing request, and if not, the power output unit of the main annular charging module is directly adopted for power output.
S202: when the power surplus of the power output unit of the main annular charging module cannot meet the power requirement of an external power supply, outputting a power sharing request to the rest annular charging modules;
after the control units of the remaining ring-shaped charging modules control and connect the contacts to close and respond to the power sharing request, the control unit of the main ring-shaped charging module is further configured to:
s203: and outputting the demand of the power output units to the rest of the annular charging modules, so that the rest of the annular charging modules control the closing of a specified number of target series contactors on the rest of the annular charging modules according to the demand of the power output units, so that the specified target power output units output power, and the target series contactors are series contactors among 2 target power output units.
In this step, the specified number is the number corresponding to the power output unit demand minus 1. For example, if the demand of the power output unit is 2, only 1 series contactor needs to be controlled to be closed to enable 2 power output units to output power. The specified target power output unit may be a specified number of target power output units or may be one of the specified target power output units.
The required amount of the power output unit is calculated according to the power requirement of the external power receiving source, and specifically, the required amount of the power sharing is obtained by subtracting the power requirement of the external power receiving source from the power surplus amount of the power output unit of the main annular charging module, and then the required amount of the power sharing is calculated according to the power surplus amount of the power output units output by the rest annular charging modules. For example, if the power surplus of the power output unit of the main annular charging module is 100KW, and the power demand of the external power supply is 300KW, the power sharing demand is 200KW, and the power surplus of the power output units of the remaining annular charging modules is 100KW, the power output unit demand is 2, that is, the power output units of the two remaining annular charging modules are required to share, so that the power demand of the external power supply can be met.
S205: and controlling a power output unit on the main annular charging module to output power.
In this embodiment, the control units of the remaining annular charging modules are configured to:
s301: and receiving a power sharing request, and judging whether the target power output unit has residual power or not according to the sharing request. Specifically, after receiving the power sharing request, it is determined whether the target power output unit has a remaining power.
S302: and when the target power output unit has residual power, sending power residual amount information to the main annular charging module, and controlling the parallel contactor to be closed.
It should be noted that the parallel contact referred to herein refers to a parallel contact between the main ring charging module and another ring power output unit.
S303: responding to a power sharing request of the main annular charging module, and receiving the demand of a power output unit of the main annular charging module;
s304: and controlling the specified number of target series contactors to be closed according to the demand quantity of the power output units, so that the specified target power output units output power.
In the embodiment, the power is shared through information interaction between the control unit of the main annular charging module and the control units of the other annular charging modules, so that the output power superposition between the main annular charging module and the other annular charging modules is realized, and the external power can meet the large power requirement of the power supply.
