Logical customer charge, another way are connected to the second charging pile group through the second power measurement instrument.
It, should by the charging station charging management system of the utility model embodiment in the embodiment of a concrete application
With the charging pile management of Mr. Yu's cell.Wherein, which is mounted with that a dry-type transformer rated capacity is 800KVA, usually
The electric power of community user entirety is 200kw-400kw, the electric power of charging pile be divided into 7kw small-powers alternating-current charging pile and
Two kinds of 40kw direct-current charging posts.
Charge power P (maximum)=（800KVA*0.9-400KW）*0.8=320*0.8=256KW
If it is fitted without Intelligent power distribution terminal, then when installing charging pile, can only estimate to calculate can go up electricity operation
The quantity of charging pile, Charge Management platform can only estimate that most 6 direct-current charging posts start or 35 alternating-current charging piles open
It is dynamic.
After being mounted with intelligent terminal, then system can real-time monitor current transformer and export electric power in real time, such as
Fruit is that safety coefficient is 80%, that can monitor transformer output power and ensure that the power does not exceed 560KVA constantly, automatically
It adjusts the power output of charging pile rather than the startup quantity of acquisition charging pile is gone by calculating maximum charge power, pass through this
The mode of the flexible electricity consumption of kind ensure that the Electrical Safety of system.
In above multiple embodiments, Intelligent power distribution terminal is due to having flexible Charge Management function, it is only necessary to survey in real time
Measure entire transformer output power value P transformers（It is practical）, ensure that the electric power is no more than the peace of the rated power of transformer
Full electricity consumption ratio, when system general power soon close to the safe range of transformer rated power when, system passes through prison
It surveys and the intelligent management platform of charging pile, the management platform is notified by its communication system with analysis electricity consumption trend, distribution terminal
It can ensure that the electric power of charging pile will not excessively increase by adjusting the charging current of charging pile in real time, avoid circuit super negative
Lotus.More charging piles can be allowed to come into operation in this way, also can guarantee the safety utilization of electric power of system；When power has reached Security alert
During line, new charging pile is locked, avoids coming into operation.（The electric current adjusted during charging is DC current, but according to conservation of energy original
Reason is inferred, when dc power reduces, exchange electric power can similarly decrease）.
In general, when charging pile works normally, constant current hold, but power is continuously increased, when most of charging pile
Power all close to it is maximum when, whole electric power is up to a peak value, this is easy to so that electricity consumption excess load.Now
By the intelligent power control algolithm of Charge Management platform, realize the charge power for adjusting every charging pile in real time, work as transformer
Overall electric power close to safety utilization of electric power power when, the electric currents of higher those charging piles of load is directly reduced, so as to drop
Low electric power consumption power, you can obtain safety utilization of electric power.Under certain conditions, it might even be possible to realize every charging pile invariable power charging, this
Sample ensures that the power load of charging pile remains unchanged always, and it is not in overload to fully ensure that circuit.This flexible charging
Control method can easily control the power load of total system, without being reserved for all charging piles more than many power
Amount can give full play to the power supply capacity of system.
