S1, battery bag status data is detected, obtain the status data of battery bag；
S2, the state to battery bag are assessed, and whether qualified assess battery bag state；
S3, charged to assessing qualified battery bag in step S2 and being in the battery bag of power shortage state.
The battery bag status data of detection includes：Distance travelled, power shortage amount after the capacity of battery bag, previous charging.
In battery bag appraisal procedure, battery bag power shortage situation is assessed according to power shortage amount testing result, after previous charging
Whether distance travelled, battery bag capacity data assess the use depreciation situation of battery bag, closed according to depreciation condition adjudgement battery bag
Lattice.
In step S2, when battery bag state estimation is unqualified, the underproof prompting of battery bag state is provided.
When battery bag state estimation is unqualified, the prompting for changing battery bag is provided, it is determined whether battery bag is changed, if
It is that battery bag is replaced with to new full electric battery bag, by the battery bag depot repair of replacing.
A kind of charging system of New-energy electric vehicle, including control unit, battery management system, charging inlet, charging
The status data of battery bag is transferred to control unit by control module, charging station, battery management system, vehicle complete vehicle controller,
Described control unit is connected with charge control module, and described charging station passes sequentially through charge control module, charging inlet connects
Connect battery bag.
Control unit connects man-machine interaction unit, and the man-machine interaction unit is used to provide replacing prompting, in man-machine interaction
After unit gets the signal for changing battery, control unit sends replacing signal to battery bag more switching center9.
The advantage of the invention is that：Can be by being assessed before charging station charges the state of battery bag, judgement is
It is no it is qualified whether need to change battery bag, when battery bag allowance for depreciation is high, unqualified, provides replacing and remind, change full electricity in time
Old battery bag is simultaneously returned factory's recovery by new battery bag, can prevent from being continuing with band when battery bag allowance for depreciation is high, unqualified
The risk come.
Brief description of the drawings
Mark in the content and figure expressed below each width accompanying drawing of description of the invention is briefly described：
Fig. 1 is electrical bicycle charging method flow chart of the present invention；
Fig. 2 is charging system of electric powercar structured flowchart of the present invention.
Embodiment
It is further detailed to the embodiment work of the present invention by the description to optimum embodiment below against accompanying drawing
Thin explanation.
As shown in figure 1, a kind of charging method of New-energy electric vehicle, comprises the following steps,
S1, battery bag status data is detected, obtain the status data of battery bag；
S2, the state to battery bag are assessed, and whether qualified assess battery bag state；
S3, charged to assessing qualified battery bag in step S2 and being in the battery bag of power shortage state.
Distance travelled after the capacity of the battery bag status data detected in step sl including battery bag, previous charging, lose
Electricity.The capacity of battery bag, power shortage amount are obtained by battery management system, and distance travelled is by entire car controller after the previous charging of vehicle
Obtain.
In step s 2, battery bag state estimation for it is unqualified when, the unqualified prompting of the battery bag state that provides, provide more
Change the prompting of battery bag, it is determined whether battery bag is changed, if so, battery bag to be replaced with to new full electric battery bag, by replacing
Battery bag depot repair.If it is not, continue to charge by battery of small-power.When judging qualified, directly for battery bag with specified work(
Rate charges.
In step s 2, the assessment of battery bag includes assessing battery bag power shortage situation according to power shortage amount testing result, according to
Distance travelled, battery bag capacity data assess the use depreciation situation of battery bag after previous charging, according to depreciation condition adjudgement electricity
Whether Chi Bao is qualified.Power shortage amount is used to judge whether battery now needs to charge, and its testing result is entered according to battery management system
Row detection, SOC is characterized with remaining electricity percent data, the power shortage situation of battery bag includes power shortage and full electric two kinds of shapes
State, it can be charged under power shortage state and under eligible state.
Whether depreciation state is qualified for characterizing battery bag, is commented with distance travelled, battery bag capacity data after previous charging
Estimate, distance travelled threshold value of warning, battery bag capacity-warning threshold value are set respectively, distance travelled threshold value of warning is arranged to specified traveling
The 30% of mileage, battery inclusion quantity are arranged to the 50% of rated capacity.Distance travelled, battery inclusion quantity are small after previous charging
When the threshold value of setting, now judge that battery bag is unqualified.Because specified distance travelled is corresponding demarcation when battery bag is dispatched from the factory
Specified distance travelled, when distance travelled is less than the threshold value set, illustrate that the outmoded endurance of battery is deteriorated；Battery inclusion quantity with
Each rechargeable battery management system detection, battery capacity is calculated by circuit current, when 50% of capacity less than rated capacity is said
Bright battery loss is serious, it is necessary to change, and is judged with both collective effects so that judged result is more accurate.Judge at battery bag
When eligible state, then battery bag is charged with specified charge power, when battery bag is in unqualified, early warning is provided and carries
Wake up.
A kind of charging system of New-energy electric vehicle, including control unit, battery management system, charging inlet, charging
The status data of battery bag is transferred to control unit by control module, charging station, battery management system, entire car controller, control
Unit is connected with charge control module, and charging station passes sequentially through charge control module, charging inlet connection battery bag.Battery management
System is for obtaining the capacity of battery bag, power shortage amount is sent in control unit, and vehicle complete vehicle controller fills for obtaining last time
Electricity is to this Rechargeable vehicle distance travelled and is sent in control unit.Control unit connects man-machine interaction unit, man-machine interaction
Unit is used to provide the underproof prompting of battery bag detection, and informing to be in for battery bag needs replacing state, passes through man-machine friendship
Mutual interface provides the prompting for changing battery bag, and for user after man-machine interaction unit inputs and changes signal, control unit thinks battery more
Switching center9 sends replacing and reminded, and reminds staff's processing.Battery altering center is made up of monitoring computer.If man-machine interaction circle
The information of face input is without changing, then control unit sends control signal and is used to control charging station pair to charge control module
Automobile batteries bag charges, while controls charge power.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as employing the methodology and skill of the present invention
The improvement for the various unsubstantialities that art scheme is carried out, within protection scope of the present invention.
