See Fig. 1 and 2, according to the Illustrative Embodiments of the present invention for vehicle
High-voltage battery Cooling Control Technology includes, controller determine for cooling down high-voltage battery
Whether Inside Air Temperature, speed and high-voltage battery temperature meet air switching in predetermined car
Request request (S100)；With work as Inside Air Temperature, speed and high-voltage battery temperature meet predetermined
Car in air handover request condition time, the refrigerating mode of vehicle is switched to air mode in car
(S300)。
Such as, in meeting predetermined car, air handover request condition (shows due to inner air temperature
Spending height, high-voltage battery is overheated) time, the refrigerating mode of vehicle is switched to air mode in car,
To stop the inner air of vehicle to be recycled to high-voltage battery.In other words, inner air is stoped
Flow into or through high-voltage battery, in order to guarantee that inner air will not unnecessarily increase
High-voltage battery temperature.
Such as, when Inside Air Temperature is too high, it can make high-voltage battery overheated.At this
In bright scope, it is contemplated that by stopping inner air blowing to the fan of high-voltage battery, can prevent
This most overheated.But, the temperature of the air owing to sucking for cooling high-voltage battery is usual
It is to measure with the suction temperature sensor being arranged in high-voltage battery, therefore the most only works as
When air has passed through high-voltage battery, just know the temperature of air for cooling down high-voltage battery,
As a result, it is difficult to stop air blowing to the fan of high-voltage battery.
When the Inside Air Temperature sucked in car is higher than high-voltage battery temperature (S101), and speed is
0km/h (S102), and high-voltage battery temperature is pre-higher than what high-voltage battery can normally work
When determining reference temperature range (S103), in predetermined car, air handover request condition is satisfied.
Such as, when Inside Air Temperature is higher than high-voltage battery temperature, high-voltage battery temperature
The probability raised is increased.Such as, when vehicle is in idling mode, in fact it could happen that this
Situation.In this case, cooling technology determines that whether speed is 0km/h, and work as high voltage
When battery temperature is equal to or less than predetermined reference temperature scope, high-voltage battery can normally be used.
Then, the pattern of vehicle need not be forced to switch to air mode in car, and does not consider to drive
The input of member.Such as, the predetermined reference temperature scope that high-voltage battery can normally work is best
It is set to about the scope of 40 DEG C～about 50 DEG C (that is, 45 ± 5 DEG C).
Preferably, when speed is at (time predetermined fiducial timedetWhen being 0 in), meet in predetermined car
Air handover request.Described predetermined fiducial time can be the most about 5 minutes～about 15 minutes
The scope of (i.e. 10 ± 5 minutes) etc.Such as, if (such as, driver leaves the vehicle long period
Equal to about 5 minutes～the time of about 15 minutesdet), then it is suitable for air handover request bar in car
Part (S102).
When in controller determines predetermined car, air handover request condition is satisfied (S100), detection
Current defrosting mode sets state, only when vehicle is not in defrosting mode (S201), just can hold
Row forces air switch step (S300) in car.
Such as, when vehicle is in defrosting mode, this generally represents that vehicle travels in the winter time, can
To keep the outer refrigerating mode of car, because the overheated probability of high-voltage battery is relatively low.Then, i.e.
In making predetermined car, air handover request condition is satisfied, and is also only not in, when vehicle, the mould that defrosts
During formula, just perform air switch step (S300) in compulsory car.
The most such as, when in controller determines predetermined car, air handover request condition is satisfied
(S100), only when the Inside Air Temperature of vehicle is higher than predetermined inner air reference temperature range
TempcabinTime (S202), just perform air switch step (S300) in compulsory car.With vehicle
In the predetermined car that Inside Air Temperature is compared air reference temperature range preferably about 45 DEG C～
About 55 DEG C (that is, 50 ± 5 DEG C).Even if air handover request condition is satisfied in car, when internal empty
When temperature is relatively low, the probability that the temperature of battery can raise is relatively low.As a result, by again
Determine vehicle interior temperature, perform air switch step (S300) in compulsory car.
Owing to defrosting mode and Inside Air Temperature all can be determined, thus example shown in fig. 2
Card embodiment considers both conditions.Obviously the two condition can consider together, or
Person individually considers, or with known to those skilled in the art, can be used for determining or regulating in advance
Other outside or inside vehicle parameter (examples various that in fixed car, when air handover request is satisfied
As, the operation of heating seat, operation of rear window defroster etc.) arbitrarily consider in combination.
Only for reference, in FIG, air handover request condition in controller determines predetermined car
When being satisfied, air handover request position in delivery vehicle, as shown in Figure 2, air in the car of transmission
Handover request position is received, and controller is air switch step (S300) in the compulsory car of final execution
Before, determine whether vehicle is in the degree that is how many of air themperature in defrosting mode, and/or car.
The process of expection Fig. 1 and the process of Fig. 2 can be performed by different controllers.Such as, arrange
Controller in the battery management system (BMS) of vehicle performs the process of Fig. 1, Full-automatic temperature
The controller controlling (FATC) performs the process of Fig. 2.
Thus, when Inside Air Temperature uprises, thus there is high-voltage battery temperature and may be risen
High to when making the overheated degree of battery, the refrigerating mode of vehicle will be forced to be set to air in car
Pattern, so that the inner air of high-temperature can not be supplied to high-voltage battery, thus reduces
The upborne probability of high-voltage battery temperature.Thus, improve the steady of high-voltage battery further
Fixed work, thus improve safety and the performance of vehicle.
Additionally, the control logic of the present invention can be embodied as comprising being held by processor, controller etc.
Computer readable medium on the computer-readable medium of the executable program instructions of row.Computer
The example of computer-readable recording medium includes, but is not limited to: ROM, RAM, CD (CD)-ROM, magnetic
Band, floppy disk, flash drive, smart card and optical data storage.Computer-readable is remembered
Recording medium also can be distributed in the computer system of network-coupled, so that distribution ground preserves and performs
Computer readable medium.
An Illustrative Embodiments according to the present invention, cools down by suitably controlling high-voltage battery
Pattern, suppresses the rising of high-voltage battery temperature to greatest extent, improves high-voltage battery
Operational stability.Above with reference to preferred embodiment, the present invention is described in detail.But, ability
Artisans will appreciate that of territory, can make a variety of changes in these embodiments, without deviating from this
The principle of invention and spirit, define the present invention's in appended claims and equivalent thereof
Scope.
