Description
Technical field
The present invention relates to the technical field of communal facility more particularly to a kind of intelligent charging station energy efficiency managing methods.
Background technology
Existing quick charge station generally uses the three-phase alternating current by three-phase distribution station to be connected to AC/DC direct-current charging posts,
There is no energy efficiency management is carried out, the capacity for pressing three-phase distribution station completely carries out the quantity of configuring direct current charging pile, is often configured
Charging pile quantity be much smaller than parking stall number；Or increase and configure the maximum capacity that spare charging pile quantity is more than distribution,
Main monitor is needed to be monitored the working condition of each charging pile by communication network, seeing if fall out distribution area allows to charge
Maximum capacity, could be filled after other Vehicular chargings are completed to select to close the charging of individual charging piles or need to wait for
Electricity.
As above it is described, direct-current charging post station (no efficiency pipe that the existing capacity for being limited power distribution station completely is configured
Reason control), the direct-current charging post quantity at this station is generally much smaller than the parking space number in parking lot, with the new-energy automobile volume of holding
Increasing, one side parking stall need to divide special new energy charging parking stall, on the other hand cannot be satisfied more vehicles while charging,
Cause energy efficiency low, the configuration of optimization is not achieved in resource.
Such as Fig. 1, the main monitoring of use at present is monitored using communication network and the system block diagram of the charging station of energy efficiency management.
Communication network can be wireless integrated control network such as CAN bus, RS485 or GPRS etc., by acquiring each charging pile
Charging status information is uploaded to main monitoring controller or computer monitoring center, by main monitoring controller calculate entire charging station or
Whether the total bulk charging load in parking lot exceeds the capacity-warning value of power distribution cabinet, to issue corresponding control instruction to each AC/
DC charging piles carry out Current limited Control or wait for charging process in turn, with distribution transformer when protection charging peak period, to prevent charging negative
Lotus overload causes network voltage to drop.
Although increase charging parking stall and spare charging pile redundant configuration, due to by power grid distribution capacity limited with
And power grid distribution capacity and the economy of charging station estimated revenue consider that the gross output of all charging piles is big in charging station
In the distribution capacity that power grid is provided.Therefore for peak period of charging, transmission monitor needs to control to ensure the station level that entirely charges
It is only capable of opening a certain number of charging piles simultaneously and charge, the vehicle of other parking stalls needs to wait for after the completion of other Vehicular chargings
Unlatching charging is carried out by master controller again, though solving the problems, such as not need Reserved Parking etc. to be charged, but still has below lack
Point：
(1), the management dependent on communication line and master controller controls, for large parking lot, the communication line of long range
Interference free performance is poor；
(2), the energy cannot be maximumlly utilized, to Mr. Yu in the vehicle of charging, the charging later stage does not need to
Power at full capacity, and have to open the charging of another vehicle after charging terminates.
