The display 36 on surface is provided on display 36 for showing status display area 361 that whether card reading unit 311 open, using
In the charging viewing area 362 for showing specifically deduct fees number and remaining sum and for the credit card area 333 of brush nfc card；In the present embodiment,
After nfc card is swiped the card in credit card area 333, status display area 361 can be bright, and the display of charging viewing area 362 is required when charging to supplement number with money
Volume and remaining sum.
The present invention provides a kind of charging method of charging pile electric energy tariffing device, includes the following steps：
Step S1, after the credit card area of nfc card over the display is swiped the card, the card reading unit controlled on chip is read in the nfc card
Information；
Step S2, judging the nfc card, whether surplus does not move back；If surplus does not move back and shows, remaining sum is retracted into the nfc card
On, it is not moved back without remaining sum such as, shows the remaining sum of the nfc card, continue to brush the nfc card；
Step S3, the unit of deducting fees controlled on chip is deducted fees, and connection charging gun is waited；
Step S4, charging gun is connected at the appointed time, is charged.
In the present invention, the working principle of charging pile：After the work of charging pile normal boot-strap, first time brush nfc card, card reading list
Member 311 reads the amount of money stored in nfc card, and is shown in charging viewing area 362, after swiping the card for the second time, according to the list of setting
Secondary value of deducting fees of swiping the card, deducts the corresponding amount of money（It can repeatedly swipe the card）, after charging pile charges to electric car, charging pile executes electricity
Metering in real time calculates the electric energy used, is converted into spending amount, and deduct, and in charging viewing area 362, display " can swipe the card and move back
Money terminates " behind interface, brush NFC carries out stopping charging, while charging pile is deposited into the remaining amount of money in nfc card.In charging pile
When non-brush nfc card stops charging, charging pile can save the amount of money that do not consume, and can be used corresponding nfc card swipe the card move back it is remaining
Volume.
The present invention provides a kind of embodiment, as shown in fig. 6, charging accounting operation is using the mould for recharging consumption of first deducting fees
Formula carries out, and the remaining sum that do not consume can be fetched by swiping the card again.
Electric energy tariffing process：
It deducts fees 1. swiping the card.It swipes the card, is shown on charging viewing area 362 on card after remaining sum, continue to swipe the card into mode of deducting fees, every brush one
Secondary card deducts Flat Amount（Such as 10 yuan or 5 yuan）, the amount of money by single deduct fees parameter card set.
2. charging process.It swipes the card and deducts fees, charging is started to charge after the completion of connection charging gun, according to electric energy unit price parameter card institute
Electricity price conversion is set, and display can fill degree on charging viewing area 362, client can be as needed, repeatedly swipes the card, and brushes into enough
The electricity charge amount of money.
3. charging terminates.Stopping charging of swiping the card may be selected in client, or powers off after being full of by charging pile judgement.It has not consumed
Remaining sum can swipe the card behind refund.
Wherein, if returning to initial standby mode without brushing second of member card in 30 seconds.
It swipes the card for the second time and starts to start to deduct fees according to the single amount of deducting fees of " single deduct fees parameter card " setting, can repeatedly brush
Card, add up the charging amount of money.
When swipe the card deduct fees successfully after, 10 minutes without connection charging gun charging, system can save the card amount of money, and jump
To initial standby mode, at this moment, it can swipe the card and move back the amount of money.
Charging pile and electric car are connected with charge cable, it is practical if charging pile band charge cable, is directly connected to vehicle end
Need to be depending on material object, when there is the amount of money on charging pile, vehicle end line cable is connected, and equipment starts to charge.
Before entering and swiping the card and stop interface, it can swipe the card and be supplemented with money to charging pile, add up the charging amount of money.
Stopping of swiping the card is charged：Stopping supplementing with money after five minutes to charging pile, " can swipe the card the display of charging viewing area 362 reimbursement knot
Beam " then can be used member card to swipe the card（Nfc card）It carries out refund and stops charging（In the case of surplus）.
It is automatically stopped charging：It has been consumed in the charging pile amount of money, charging pile can be automatically stopped charging, and charging gun is pulled out from vehicle side
Under, then return to original state.
Failure stops charging：In faulty situation, charging pile self-test stops charging, is not pulling out charging gun, charging is shown
Area 362 can show fault code.
Refund operation：Swiped the card the remaining sum moved back on charging pile according to 362 prompt information of charging viewing area, when in a period of time not
It swipes the card refund, charging pile can be recorded in memory remaining sum, and client can swipe the card behind and fetch remaining sum；Charging pile operates every
One step has corresponding display reminding on 362 screen of charging viewing area, please carries out according to prompt information on charging viewing area 362
Operation；Charging pile can only record ten remaining sum values, if it exceeds ten, subsequent record can cover the record value of front, need
It reminds charging pile user to swipe the card in time and fetches remaining sum.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
