Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is circuit principle structure schematic diagram of the present utility model.
Embodiment
With reference to accompanying drawing, this charging system for electric automobile comprises charging pile system, automobile power battery system, the charging socket 2 that is connected to the charging plug 1 in charging pile system and is arranged in automobile power battery system, and charging plug 1 and charging socket 2 all lead to power supply lead wire and signal lead; The power supply lead wire of charging plug 1 connects successively power converter 5, rectifier 4 and general supply 3; the signal lead of charging plug 1 is connected with charging pile controller 6; charging pile controller 6 is connected with power converter 5 by electric current, voltage control circuit, also arranges protective circuit between charging pile controller 6 and power converter 5.Charging pile controller 6 connects man-machine interface 7, man-machine interface 7 is arranged charge mode selection key 8, charging interval selection key 9 and start and stop button 10; The power supply lead wire of charging socket 2 is electrically connected with electrokinetic cell 12, and the signal lead of charging socket 2 is connected with battery management system 11, electrokinetic cell 12 is arranged charging relay 13, and the control end of charging relay 13 is connected with battery management system 11.Charging pile arranges man-machine interface 7, convenient to operation; Charging interval selection key is set separately, charging pile controller 6 according to charging interval reasonable distribution charging current, can be avoided always with larger current charging, thus improve battery; Mode selection button 8 is set, according to vehicle needs and network load situation, automatic mode and artificial mode can be selected, thus can conservation of power, improve utilization rate of electrical.
With reference to accompanying drawing, signal lead comprises the charging voltage maximum value signal line of transmitted in both directions, charging current maximum value signal line and the charging voltage line value signal transmitted to charging pile controller 6 by battery management system 11 and charging current line value signal.Signal lead also comprises battery electric quantity holding wire and battery status signal line.Wherein, battery status signal is mainly battery temperature signal, and electrokinetic cell 12 is provided with temperature sensor 14, and the signal output part of temperature sensor 14 is electrically connected with battery management system 11.The temperature of temperature sensor 14 Real-Time Monitoring electrokinetic cell 12, stops charging when battery temperature is too high, ensures charging security.
Wherein, for charge mode, if (can voice message be arranged) within 10 seconds, user selects artificial intelligence pattern, according to prompt tone, need carry out the charging interval to select to arrange, arrange the charge cutoff time, charging pile controller calculates charging current I according to the technical parameter of the electrokinetic cell that user's input time and BMS send over
c, with charger maximum charging current I
jcompare, the medium and small current value of both selections is as the charging current value of charger, the higher permission charging current I fed back with BMS
bcompare, if charger electric current is less than the threshold limit value of BMS feedback, by the charging of charger end current value, otherwise then press the highest permission current value charging of BMS feedback.
If in 10 seconds (after voice message), charge user is selected automated intelligent pattern or is not carried out charge mode selection after 10 seconds, and charging pile acquiescence enters automatic charging pattern.
In automatic mode, time point when charging pile controller charges according to user carries out intelligent decision: might as well establish a certain certain evening hours point T, when charging before T, directly carry out parameter between BMS and charger and confirm alternately, select larger current charging according to BMS demand; After T, charging pile is defaulted as user can not useful car demand in night, and charging pile can according to the time T in T and second day early morning
1determine the duration that charges, according to the residual electric quantity determination charge capacity Q of BMS feedback
c, thus calculate charging current, if the charging current that this current value is less than BMS permission according to this current charges, otherwise can press the charging of BMS feedback current.Large current charge can be avoided to produce too much heat in summer like this, and make cooling blower intervention work, consume too much electric energy; The low current charge continued in the winter time can ensure that the temperature of battery can not reduce with ambient temperature, and battery is without the need to heating in advance, and electrokinetic cell ensures to be in high-effect state, is not damaged in the high-power output situation of protection battery.
In a manual mode, electric automobile user was arranged according to its actual user demand for the charging interval of electrokinetic cell, as user's urgent need car, ited is desirable in its official hour, be full of electricity or fill electricity as much as possible.So user can arrange to arrange the shorter charging interval according to self; If no hurry for user with car, can be set according to self-demand the longer charging interval.Because large current charge will much larger than low current charge for the damage in electrokinetic cell life-span, arranging the charging interval can on the basis meeting user's user demand, reduce large current charge as far as possible to the impact of battery, so user is ready to arrange the charging interval according to self-demand.
In sum, the utility model is not limited to above-mentioned embodiment.Those skilled in the art, under the prerequisite not departing from spirit and scope of the present utility model, can do some changes and modification.Protection range of the present utility model should be as the criterion with claim of the present utility model.
