Detailed Description
With reference to the logical structure diagram of the embodiment of the present invention shown in fig. 1, the management system of the embodiment specifically includes a connection confirming unit 1, a communication unit 2, an information obtaining unit 3, a power allocating unit 4, and a calculating unit 5.
The connection confirmation unit 1 is used for confirming whether the charging gun is connected with the automobile A to be charged or not; the communication unit 2 is configured to transmit the charging requirement and the priority of the vehicle a to be charged to the calculation unit 5 and the power allocation unit 4, respectively, when it is determined that the charging gun is connected to the vehicle a to be charged.
The information acquisition unit 3 is used for acquiring priority and charging demand information of the automobile a to be charged, and marking each automobile in a charging automobile as a charging automobile b1, a charging automobile b2 and a charging automobile b3 respectively; the priority is a comparison factor which takes quick charging or slow charging as the first priority, the quick charging priority is high, and the slow charging priority is low; when the primary comparison parameters are the same, the morning and evening of the charging start time are taken as secondary comparison factors, the priority of the charging start is high, the priority of the charging start is low, and obviously, whether the member is present or not, the brand of the vehicle and the like can also be taken as factors influencing the priority.
The power allocating unit 4 allocates power to the vehicle a to be charged and the vehicle (b 1, b2, b 3..) to be charged according to the priority of the vehicle a to be charged and the vehicle (b 1, b2, b 3.. said.) to be charged and the charging requirement of the vehicle a to be charged, so as to meet the charging requirement of the electric vehicle with high priority preferentially.
And the calculating unit 5 is used for determining the number m of the power units required by the charging of the automobile A to be charged according to the charging requirement of the automobile A to be charged and the output power of the power units.
Fig. 2 is a logical structure diagram of an embodiment of the power scheduling unit in fig. 1, where the power scheduling unit of the embodiment includes: a comparison unit 41, a first confirmation unit 42, a first determination unit 43, a first distribution unit 44, a second distribution unit 45, a second determination unit 46, a third distribution unit 47, and an alarm unit 48.
Firstly, after the connection confirming unit 1 confirms that the charging gun is connected with the automobile A to be charged, the information obtaining unit 3 obtains the priority and the charging demand information of the automobile A to be charged, the communication unit 2 respectively transmits the charging demand information and the priority of the automobile A to be charged to the calculating unit 5 and the power allocating unit 4, the calculating unit 5 determines the number of power units required by charging of the automobile A to be charged, and transmits the number of the required power units to the power allocating unit 4.
Preferably, when the comparison unit 41 in the power dispatching unit 4 compares that the priority of at least one electric vehicle in the charging vehicles is lower than the priority of the vehicle a to be charged, the first confirmation unit 42 confirms the electric vehicle with the lower priority as the charging vehicle B. When the first judging unit 43 judges that the number of the currently idle power units is greater than or equal to m, the first distributing unit 44 selects m power units from the currently idle power units to distribute to the automobile a to be charged; when the first determination unit 43 determines that the number of the currently idle power units is smaller than m, the second allocation unit 45 allocates the currently idle power units to the vehicle a to be charged, sequentially releases the power units already allocated to the vehicle B to be charged, and allocates the released power units to the vehicle a to be charged until the number of the power units allocated to the vehicle a to be charged reaches m. Further, when the number of the charging vehicles B is greater than 1, the second allocating unit 45 sequentially releases the plurality of power units occupied by the charging vehicles B in the order of priority from low to high of the plurality of charging vehicles B, and allocates the released power units to the vehicle a to be charged until the number of power units allocated to the vehicle a to be charged reaches m.
Preferably, when the comparing unit 41 determines that the priority of none of the electric vehicles in the charging vehicle is lower than the priority of the vehicle a to be charged, the second determining unit 46 determines whether the number of the currently idle power units is greater than or equal to m, and if the number of the currently idle power units is greater than or equal to m, the third allocating unit 47 selects m power units from the currently idle power units to allocate to the vehicle a to be charged; if the number of the currently idle power units is less than m, the third distribution unit 48 distributes all the currently idle power units to the vehicle a to be charged. If the number of the current idle power units is 0, the warning unit sends a charging instruction to the vehicle A to be charged until the charging of the vehicle A is completed, and the idle power units are released and redistributed to the vehicle A to be charged for charging.
By implementing the technical scheme of the embodiment, when a public charging facility is used for charging a plurality of electric automobiles, if a new electric automobile is connected with the current public charging facility, the priority of each electric automobile is obtained, the priority sequence of each electric automobile is readjusted, then the number of the power units distributed to each electric automobile is adjusted according to the sequence of the priority of the electric automobile from high to low and the charging requirement of each electric automobile, and the like.
