Stopping of swiping the card is charged：After stopping supplementing 5 minutes with money to charging pile, charging viewing area 362 shows that " can swipe the card reimbursement knot
Beam ", then member card can use to swipe the card（Nfc card）Carry out move back expense and stop charging（In the case of surplus）.
It is automatically stopped charging：Consumed in the charging pile amount of money, charging pile can be automatically stopped charging, and charging gun pulls out from car side
Under, then return to original state.
Failure stops charging：In the case of faulty, charging pile self-test stops charging, is not pulling out charging gun, charging is shown
Area 362 can show failure code.
Move back expense operates：Swiped the card according to the prompt message of charging viewing area 362 remaining sum moved back on charging pile, when in a period of time not
Swipe the card move back expense, charging pile can record remaining sum in memory, and client can behind swipe the card and fetch remaining sum；Charging pile operates every
One step, there is corresponding display reminding on the screen of charging viewing area 362, please carried out according to prompt message on charging viewing area 362
Operation；Charging pile can only record ten remaining sum values, if it exceeds ten, record below can cover record value above, need
Remind charging pile user to swipe the card in time and fetch remaining sum.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
