It is intended to.As shown in Figure 1, power battery heat management/charging management system 10 of the embodiment of the present invention includes vehicle usage time
Point determining module 110 and charge control module 120.
Since in electric automobile application field, electric automobile is after first use, there are longer period always
Without using the situation driven until next time, however, in the case where environment temperature is low, for example, the severe cold winter in the north, temperature can
To reach -20 degrees Celsius, at the time point that next time drives, temperature of powered cell also will be too low, in view of the characteristic of power battery,
Electric automobile can just drive to make before use, be to need to carry out after being heated to suitable or suitable temperature power battery
With performance and the service life of power battery otherwise can be seriously affected.Power battery heat management/Charge Management system of the embodiment of the present invention
System 10 is primarily but not limited to be conceived to the temperature of the power battery at driving time point next time under relatively low ambient temperature conditions
Control.
It is big at present to solve the problems, such as that power battery is too low in next time point temperature also, present inventor has found
Most power battery suppliers or electric automobile producer are to the heat management of power battery substantially by the way of passively keeping the temperature（Example
Such as, use thermal insulation material to power battery increase etc.）Or the mode of relative complex active heating（It is for example, all by increasing
As PTC device directly or indirectly heats power battery）.But both the above mode all there are it is certain the defects of, quilt
The mode soaking time first of dynamic insulation will not be too long, and for a long time in low temperature environment, temperature still can mistake in power battery
It is low, particularly under the conditions of extreme harsh climate, secondly as there are thermal insulation material, and when can bring the power battery to run
Heat dissipation problem；Actively on the one hand the mode of heating can bring the loss of energy, and on the other hand actively heating needs the regular hour,
User's in-use automotive time point needs time-consuming wait, reduces user experience；Also, both the above mode can all increase electric automobile and exist
Cost in terms of heat management.
Power battery heat management/charging management system 10 of the embodiment of the present invention can on the entire car controller of electric automobile
To set vehicle usage time point determining module 110, after car is used every time, for example, when parking or parking, pass through the vehicle
Usage time point determining module 110 determines that the next time of user drives time point, if the time before time point of driving in next time
Section is longer（Namely down time is longer）, easily too low by cold ambient temperature effect there are power battery, then sending should
Next driving time point information is to charge control module 120, to be ready for heat management control.
In one example, driving habit analysis submodule 111 is provided with vehicle usage time point determining module 110, is driven
The drive routine custom data of such as automobile can be collected or obtain by sailing custom analysis submodule 111（Such as start-stop time point letter
Breath）, can analyze obtain user's car time point rule distribution situation, if for example, user every morning for the moment
Between point start to use car, can be in evening by the startup time point relevant historical data of collection analysis period every morning vehicle
Analysis obtains during upper parking drives time point next time of the next morning, or even more accurately, can be according to the next morning
What day etc., the corresponding historical data of Accurate Analysis come predict more accurately next time drive time point.It should be noted that drive
Custom analysis submodule 111 is analyzed and processed the drive routine custom data of user and is driven the time with the next time for predicting user
The specific method of point is not limited to above example.
Also, if when driving habit analysis submodule 111 predicts that obtained next time drives time point apart from this parking
Between the time interval put be less than certain value（For example, the time interval will not cool to power battery under current environmental temperature
A certain temperature）, vehicle usage time point determining module 110 can be ignored drives time point next time, namely does not send it to
Charge control module 120.
In a further example, vehicle usage time point determining module 110 can by from intelligent mobile terminal 140 when
Between data come determine user next time drive time point.For example, corresponding APP applications, user are installed in intelligent mobile terminal 140
After parking（If the parking time is grown, such as enters garage parking at night）, can input and drive time next time in APP applications
Point（Such as 8 points of the next morning）, intelligent mobile terminal 140 can with the entire car controller interactive communication on electric automobile,
Can with 110 interactive communication of vehicle usage time point determining module, so as to vehicle usage time point determining module 110
The next driving time point information inputted, and determined and sent to charge control module 120.In another example intelligence
Mobile terminal 140, which installs corresponding APP applications, can automatically extract making a noise in the alarm clock setting application of the intelligent mobile terminal 140
Clock timing information（For example, 7 points of the next morning）And send to vehicle usage time point determining module 110, vehicle usage time
Point determining module 110 can increase or postpone predetermined amount of time on the time point of the alarm clock timing information（Such as 1 it is small when）Come
Determine that the next time of user drives time point（For example, 8 points of the next morning）；Specifically, the driving that can combine above example is practised
The drive routine custom data that used analysis submodule 111 gathers（Such as the startup time of every morning）With alarm clock timing information ratio
Compared with to determine the length for the predetermined amount of time for needing to increase on the time point of alarm clock timing information or postponing, in this way, can be more accurate
Really determine that next time drives time point.
In yet another example, the default time that can directly be set in entire car controller, which is vehicle
The next time that usage time point determining module 110 determines drives time point.
It is to be appreciated that vehicle usage time point determining module 110 determines the mode at driving time point next time of user
Above example is not limited to, also, " next time drives time point " is not specifically limited to a certain accurate time point, for example, it can
To be the time in the range of certain time period, for example, using half an hour or shorter period as time point.
Continue as shown in Figure 1, charge control module 120 can obtain next driving time point information, charge control module
120 determine to wake up the start time point of charging at time point according at least to drive next time, and by controlling onboard charger etc. to realize
Charging is proceeded by the start time point, so that power battery can be realized corresponding by the spontaneous heating of charging process
Driving next time time point relative ambient temperature is warming up to predetermined temperature（Such as 10 degrees Celsius or 20 degrees centigrade）, the predetermined temperature
It can be determined according to the concrete property of power battery, it is generally suitable power battery output power driving electric automobile during traveling
Temperature, or relevant temperature specified in respective standard.
The period model at the start time point for the wake-up charging that charge control module 120 determines driving time point next time relatively
In enclosing, the spontaneous heating charged if based on a certain charge power of onboard charger, can realize power battery from current
Environment temperature is warming up to the predetermined temperature, then shows that user can directly initiate electric automobile at the driving time point next time and drive
Sail use, it is not necessary to which wait to power battery preheating, need not more set power battery thermal insulation material or the similar masters of PTC
Dynamic heating equipment, the cost of implementation of power battery heat management are low.
In one embodiment, when determining to wake up the start time point of charging, not only need to consider power battery in next time
Whether driving time point can be warming up to predetermined temperature, it is also necessary to consider whether power battery is charged to predetermined state-of-charge
（Such as charge to 100% state-of-charge）, this is because, for automobile user, an important side of user's concern
Face is electric running mileage.For this reason, in this embodiment, charging is provided with power battery heat management/charging management system 10
Duration prediction module 130, charging duration prediction module 130 can be, but not limited to set in the ECU of electric automobile, its according at least to
The state-of-charge and environment temperature of power battery calculate the duration charged to needed for predetermined state-of-charge, such as charge to 100%
Duration needed for state-of-charge.It is to be appreciated that parking or during parking every time, the current state-of-charge of power battery is can be with
Obtained from battery management system, in view of the use habit of electric automobile, when driving terminates to be stopped for a long time, user
Before next time drives it is expected power battery charging to the higher level of state-of-charge.The duration prediction module 130 that charges is pre-
The duration information of survey can be sent to charge control module 120, and charge control module 120 can be based on the duration and true before
Drive time point to determine to wake up the start time point to charge fixed next time.Specifically, the start time point for waking up charging is equal to
Driving time point next time at least subtracts the duration of prediction；If charging duration prediction module 130 predicts that required duration is longer, call out
The start time point to charge of waking up relatively next time point of driving then needs to shift to an earlier date.
To improve the accuracy that charging duration prediction module 130 calculates charging duration, charging process can be taken into consideration and moved
Temperature change caused by power battery spontaneous heating, namely influence of the power battery spontaneous heating to charging rate based on charging process come
Determine the charging duration, for example, can realize according to power battery under condition of different temperatures with the associate feature of charging rate come
Calculate the charging duration.Specifically, when calculating the charging duration, it is also necessary to which considering the charge power of charging process influences, base
Different charging durations can be calculated in different charge powers.
In one embodiment, charge control module 120 is additionally configured to drive time point and environment temperature according at least to next time
Degree determine charging end time point, if environment temperature is lower, charging end time point can be separated by next time drive time point get over
It is short, in this way, power battery mistake again will not be caused within the period charged between end time point and drive next time at time point
It is cold.Specifically, the end time point that charges can drive 15-40 minutes morning at time point next time relatively, for example, in the charging end time
Point is driven early 30 minutes time point next time relatively, in this way, charge control module 120 will drive to stop within 30 minutes before time point in next time
Only charge, also avoid battery charging caused heat affecting to start power battery output.
Illustratively, if according to current state-of-charge predict charging when it is a length of 4 it is small when, next time drive time point be morning
8 points, it is desirable to shift to an earlier date half an hour compared to drive next time at time point（Combining environmental temperature determines）Complete charging, then charge control
What module 120 determined, which wakes up the start time point to charge, is（8-4-0.5）=3.5, i.e. 3:00 AM half, charge control module 120
Definite charging end time point is or so 7 thirty of morning.In this way, 8 points of user is driven when using car, not only power battery is filled
It is full, moreover, the proper temperature of power battery, can drive at once, it is not necessary to wait, user experience greatly improves.
Continue as shown in Figure 1, the intelligent mobile terminal 140 of power battery heat management/charging management system 10 is controlled with charging
120 interactive communication of molding block, so as in the relevant information of the display charging of intelligent mobile terminal 140, be moved in real time for example, showing
Whether power battery has been successfully connected charging interface, display charged state, display charging complete etc..In this way, user can be long-range
Obtain the relevant information of charging.Intelligent mobile terminal 140 specifically can be, but not limited to as smart mobile phone or tablet computer etc..
It should be noted that before charging starts, i.e., it is necessary to complete charging standard before the start time point of charging is waken up
Standby work, such as power battery is connected into charging interface, electric automobile whole is in chargeable state, and then automobile enters sleep
Pattern, the start time point until waking up charging, automobile automatically wake up and are charged by such as onboard charger.
Fig. 2 show the flow diagram of power battery heat management/charging management method according to one embodiment of the invention,
Fig. 3 show the principle schematic for the start time point for determining to wake up charging.Below in conjunction with Fig. 1 to Fig. 3 to the embodiment of the present invention

Status information, i.e. step S211；Otherwise, push shows fault message, reminds user to check whether charging interface connects.
Further, step S220, prediction charging duration.In this step, state-of-charge, ring that can be according to power battery
The spontaneous heating of border temperature, charging process（Possibility temperature change of the power battery in charging process）And/or charge power etc. comes
Calculate duration power battery being filled to needed for predetermined state-of-charge.The step can pass through the duration prediction module that charges
130 complete and send to charge control module 120.
Further, step S230, the next time for determining user by vehicle usage time point determining module 110 drive the time
Point.Driving time point next time specifically determines principle, and with reference to shown in Fig. 3, time point determining module 110 can be obtained from such as four
The data of a aspect.First aspect is to drive time point the next time that driving habit analysis submodule 111 is predicted according to historical data,
The drive routine custom data of such as automobile can be collected or obtained to driving habit analysis submodule 111（Such as start-stop time point
Information）, the rule distribution situation at the time point for obtaining user's car can be analyzed, so that according to current parking time point, in advance
Next time is surveyed to drive time point；Second aspect is alarm clock timing information of the extraction from intelligent mobile terminal 140（Referring to step
S231）, increase predetermined amount of time on the time point of the alarm clock timing information（Such as 1 it is small when）To determine that the next time of user drives
Time point；The third aspect is the default time directly set in entire car controller, which is to drive the time next time
Point；Fourth aspect is to drive time point the next time that the user from intelligent mobile terminal 140 directly inputs（Referring to step S231）.
At least one of the data of above many aspects may serve to determine that next time drives time point, therefore, in vehicle usage time
Point determining module 110 can set two priority classes submodule, when receiving the data of many aspects, to the plurality of aspect
Data sort by priority, and vehicle usage time point determining module 110 determines next time using the of a relatively high data of priority
Drive time point, for example, the data of above fourth aspect be highest priority data, if having received it is input by user under
Secondary driving time point, then directly ignore otherwise data, directly determine that next time drives time point based on the data.It is specific excellent
First level order can be good by rule setting in advance.
And it is to be appreciated that many data can also select at least two to combine for determining that next time opens above
Car time point, for example, with reference to the data of above first aspect and second aspect come determine next time drive time point.
It should be noted that the sequencing between above step S220 and step S230 is not limiting, they can
To synchronously complete, step S220 can also be first completed, can also first complete step S230.
Further, step S240, determines to wake up the start time point of charging.In this embodiment, filled referring to Fig. 3, wake-up
