Embodiment Construction
[0034] The purpose of the present invention is to provide a charging system and its charging power dynamic allocation method, which is used to solve the problem of unbalanced utilization rate of the AC / DC conversion module in the charging pile in the prior art, and can also solve the problem when one of the charging piles When the charging power is large, the adjacent charging piles cannot.
[0035] To achieve the above object, the technical solution provided by the invention is:
[0036] A charging system, including a charging gun, a processor and at least two AC / DC modules; each AC / DC module is connected to the charging gun, and a corresponding contactor is provided on the line connecting each AC / DC module to the charging gun; each The AC / DC module is divided into at least two module groups, each module group includes at least one AC / DC module; the processor is used for:
[0037] Determine the priority of each module group;
[0038] When it is necessary to charge the vehic...

The invention provides a charging system and a charging power dynamic allocation method thereof. The charging system comprises a processor and at least two AC / DC modules; each AC / DC module is dividedinto at least two module sets, and each module set comprises at least one AC / DC module; the processor is used for determining the priorities of all module sets; when a vehicle needs to be charged, thequantity of module sets needed for charging the vehicle is determined according to the charging power of the vehicle, a corresponding quantity of module sets are selected according to the descendingorder of the priorities, a corresponding contactor is controlled to connect the module sets and the vehicle, and the vehicle is charged. According to the technical scheme, the module sets are subjected to priority dividing according to the using conditions of all the module sets, the module sets with higher priorities are firstly put into use, the module sets with lower priorities are put into uselater, the module sets can be randomly switched among multiple charging requirements, the using balance of all AC / DC conversion modules is guaranteed, and the service life of the AC / DC conversion modules is prolonged.
Description
technical field [0001] The invention relates to the technical field of electric vehicle charging control, and specifically relates to a charging system and a method for dynamically distributing charging power thereof. Background technique [0002] At present, the energy of traditional fuel vehicles mainly depends on oil, and the shortage of oil and the serious pollution of the environment caused by the tail gas of fuel emissions have made it more and more urgent for human beings to research new green vehicles. As a green transportation tool, electric vehicles not only have remarkable energy-saving effects, but also greatly improve the comprehensive utilization rate of energy, and have zero exhaust emissions and obvious environmental benefits. Therefore, the use of electric vehicles is becoming more and more widespread. [0003] The power of electric vehicles comes from power batteries, and the slow charging speed and short cruising range of power batteries have always been t...
