The method of above scheme design expects the comparison of temperature rise value and the first temperature rise value by the first of charging equipment, If charging equipment can be full of by representing current charged level not above the first temperature rise value, the influence of temperature is considered to count Charging remaining time is calculated, so that charging equipment charging remaining time is more accurate, the display in final charging time is also more acurrate, It will not jump, influence the experience of user.
For step 101, what needs to be explained here is that, monomer voltage and current temperature also have relationship, so needing root Common judgement is carried out according to current temperature and monomer voltage.
Optionally, for step 101 further include: periodically read the Current Temperatures of charging equipment, monomer voltage with And current residual electricity.
The method of above scheme design, needs to charge by periodically reading Current Temperatures, monomer voltage and residue Electricity, the update in Lai Jinhang charging time, improve charging remaining time accuracy, and allow users to understand charge into Journey, grasps the progress of charging, greatly enhances the experience of user.
For step 102, what needs to be explained here is that, the number of degrees of the charging current levels in the application should not be limit The condition of the application processed, in a particular embodiment, we, which illustrate, is followed successively by 1c, 0.5c, 0.25c, 0.125c, 10A, 5 chargings Current class.It can get the current class for currently needing to charge according to current temperature and monomer voltage inquiry charging Map table, by It is different in the battery battery core material of each vehicle, thus into the different charging stages temperature and monomer voltage range not yet Together.
Optionally, for be charged according to current residual electricity and the estimation of current charging current levels in step 103 First charging time of the equipment under current charged level, concretely:
According to the first formula QCharging=Q-QIt is remaining-QTrickleThe electricity for needing to charge is determined, according to the second formula T1=QCharging/I1Really The first charging time under settled preceding charged level, wherein QChargingIndicate that the electricity for needing to charge, Q indicate that the charging equipment is total Electricity, be known quantity, can by read charging equipment hardware parameter etc. be achieved with, QIt is remainingIndicate current residual electricity, It is obtained by reading, is known quantity, QTrickleIndicate that the charge capacity of the trickle under current flow grade, the trickle of different phase fill Power consumption is different, can be as obtained by demarcating early period, T1Indicate the first charging time under current charged level, I1Expression is currently filled The size of current of electric current class is determined according to the current class of different phase.
For the fitting according to the first charging time and the first charging time and charging equipment temperature rise in step 103 Function estimates the first estimated temperature rise value of charging equipment;It is concretely: according to above-mentioned T1And T1With the fitting letter of temperature rise Number y=kx+b determine the first estimated temperature rise value of the charging equipment, wherein y indicates the first estimated temperature rise value, and x represents the One charging time T1, it is known quantity, by bringing the first charging time of above-mentioned calculating into fitting function y that k and b, which indicate coefficient, =kx+b, so that it may calculate the first estimated temperature rise value y.
Optionally, for reaching the temperature spot of drop stream in step 104 according to the Current Temperatures of charging equipment and currently Determine the first temperature rise value, specifically: according to third formula TTemperature rise 1=TDrop stream-TCurrently, wherein TTemperature rise 1Indicate the first temperature rise value, TDrop streamTable Show the temperature spot for currently reaching drop stream, TCurrentlyCurrent temperature value is indicated, what needs to be explained here is that under different charging current levels It is different when drop stream temperature spot.
Trickle charging time in step 106 can be obtained by the calibration of early period.
For above-mentioned steps, when a charging equipment is charged, it is to be charged concretely the first scene: to read this The Current Temperatures of equipment, monomer voltage and remaining capacity determine the charging equipment according to Current Temperatures and monomer voltage It is the 1c stage into charged level, passes through QCharging=Q-QIt is remaining-QTrickleIts electricity for needing to charge is calculated, T is passed through1=QCharging/I1c Its first charging time is calculated, according to T1And fitting function y=kx+b obtains its first estimated temperature rise value y, according to TTemperature rise 1= TDrop stream-TCurrentlyIt obtains the first temperature rise value (namely theoretical temperature rise value), judges whether y is greater than TTemperature rise 1If it is not, then charging time Equal to T1In addition trickle charging time.
Optionally, as shown in Fig. 2, after judging the first estimated temperature rise value whether more than the first temperature rise value in step 105, Further include step 107: if being more than, entering next charging current levels after reducing charging current levels, go to step 108.
Step 108: remaining capacity and next charging current levels when according to next charging current levels are estimated wait fill Second charging time of the electric equipment under next charged level, according to the second charging time and the second charging time and to be charged The fitting function of equipment temperature rise determines the second estimated temperature rise value of charging equipment, goes to step 109.
Step 109: the second temperature rise value being determined according to the temperature rise of current drop stream temperature spot to next drop stream temperature spot, goes to step Rapid 110.
Step 110: judging that the second estimated temperature rise value whether more than the second temperature rise value, goes to step 111.
Step 111: if being not above, by the second charging time along with the trickle under next charging current levels fills The electric time calculates the charging remaining time of charging equipment.
Specifically, above-mentioned steps concretely the second scene: in the first scene according to TTemperature rise1=TDrop stream-TCurrentlyObtain the first temperature Appreciate (namely theoretical temperature rise value), judges whether y is greater than TTemperature rise 1When, if y is greater than TTemperature rise 1, then enter 0.5c charging current etc. The grade stage charges according to the charging current levels of remaining electricity and 0.5c estimation after charging under 1c charged level in 0.5c The second charging time under grade determines the second estimated temperature rise value y2, root according to the second charging time and fitting function y=kx+b Drop stream temperature spot under Current Temperatures and 0.5c charged level when accordingly determines the second temperature rise value, judges whether y2 is greater than second Temperature rise value, if not having, remaining time of charging is equal to the second charging time plus the trickle charge under 0.5c charging current levels Time.
If judging y2 again no more than the second temperature rise value, when subsequent 0.25c, 0.125c and 10A and above situation It is identical, in addition what needs to be explained here is that, if drop flows to stage of low current, such as 10A charging current levels rank herein Section, since charging current is natively smaller, so when calculating remaining charge volume and charging remaining time, relative to front For, the charging time of charge capacity and trickle without trickle.
Optionally, for being filled by the first charging time plus the trickle under current charging current levels in step 106 The electric time calculated after the charging remaining time of charging equipment, further includes: according to the charging remaining time and according to charging The unit price of time-based charging calculates the charging electricity charge of the charging equipment.
The electricity charge of the method for above scheme design, charging can be obtained according to charging remaining time, so that automobile charges Electricity charge transparence, come into the open, client can recognize the electricity charge calculating process of charging at any time.
