Also include charging management method:
Automobile charging pile is set up with serial bus system for the first time by charging gun after being connected, and it is total that automobile charging pile reads serial
Vehicle VIN code message in wire system also sends to central server, it is achieved knee is bound；
Automobile charging pile is for using peak-trough electricity charging charging pile, if current time is in paddy electricity chargeable time, automobile fills
Electric automobile is charged by electricity stake；
If current time is in outside paddy electricity chargeable time, central server one base of assignment to each automobile charging pile
Plinth power threshold W, basis power threshold central server reads current time, paddy electricity chargeable time opening time and Current vehicle
Battery electric quantity value A, central server calculates current time and paddy electricity chargeable time open-interval difference and draws time difference
T；
Central server calculates Am1+Tm2, m1And m2For the weight coefficient set, work as Am1+Tm2>=W is then judged to forbid filling
Electricity, works as Am1+Tm2＜ W is then judged to need charging, and electric automobile is charged by automobile charging pile.
Concrete example is as follows, if being Saturday, measurement period is one week today, then as Saturday last week borrow train number number be 5 times, then
As borrowed Saturday week before last train number number to be 7 inferior, multiple measurement period average computation are got off, and at this point put Saturday is 5 by means of car quantity
Secondary, basis charge value is the 50% of total electricity, and percent coefficient is 2%, then can show that basis power threshold is 50%+
2%*5=60%, is the 60% of total electricity, if current time is 9 points, paddy electricity chargeable time is 10 points, then current time
Difference is 1 hour.Set m1=0.9, m2=0.05, if battery electric quantity value is total electricity the 50% of Current vehicle, then Am1+
Tm2=0.9 × 50%+0.05 × 1=50%, the basic power threshold less than 60%, it is determined that charge for needs, automobile charging pile
Electric automobile is charged.
If battery electric quantity value is total electricity the 65% of Current vehicle, then after basis quantity coefficient value is divided by time difference
The numerical value drawn is Am plus the battery electric quantity value of Current vehicle1+Tm2=0.9 × 65%+0.05 × 1=63.5%, is more than
The basic power threshold of 60%, it is determined that charging for needs, electric automobile is charged by automobile charging pile.
If similar multiple measurement period average computation get off at this point put Saturday by means of car negligible amounts, basis electricity threshold
It is worth relatively low, more difficult reaches charge threshold.
