Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
As shown in Figure 1, power accumulator thermal management algorithm of the present invention comprises the steps:
Step S1: the temperature obtaining each test point of power accumulator, this test point at least comprises the air inlet test point T22 being positioned at power accumulator air inlet 21 place as shown in Figures 2 and 3, at this, the temperature of each test point is obtained by receiving the temperature signal of corresponding test point that the temperature sensor that is arranged on each test point collects, test point T24 on the left of the air outlet that this test point such as also can comprise two side positions being positioned at power accumulator air outlet 26, test point T25 and the point of the intermediate examination and measurement between power accumulator air outlet 26 and power accumulator air inlet 21 T23 etc. on the right side of air outlet.
Step S2: when the arbitrary heat management open event of generation being detected, aircondition is opened with heat management pattern, the temperature that this heat management open event comprises test point exceeds the operating temperature range of power accumulator, this can need the temperature being designed to all test points all to exceed the working temperature of power accumulator according to use, or the temperature of any one or wherein several test point exceeds the operating temperature of power accumulator, the operating temperature range of this power accumulator is generally-10 DEG C to 50 DEG C, namely in the temperature of power accumulator lower than-10 DEG C or higher than above-mentioned heat management open event occurs when 50 DEG C, at this, open aircondition with heat management pattern should be understood to: if now aircondition is opened, then directly enter heat management pattern, this heat management pattern can't affect the air conditioning mode that driver has selected, but the air conditioning mode that driver has selected can affect the temperature of the air-conditioner air outlet entering heat management pattern, the two can realize controlling the temperature of crew module and power accumulator respectively, if now aircondition is not opened, be then first open aircondition, then make aircondition enter heat management pattern.
Step S3: after aircondition enters heat management pattern, obtain the temperature of air-conditioner air outlet and the ambient temperature of crew module, because namely aircondition itself possesses this crew module's temperature sensor, the temperature signal collected by receiving crew module's temperature sensor obtains the ambient temperature of this crew module, in addition, the temperature signal that the air-conditioner air outlet temperature sensor T1 being arranged on air-conditioner air outlet 11 place by reception collects obtains the temperature of this air-conditioner air outlet.
Step S4: whether the temperature detecting power accumulator air inlet is consistent with the target temperature of heat management pattern, as otherwise perform step S5, then exit heat management pattern in this way, the scope of this target temperature is generally 24 DEG C to 32 DEG C, such as, can target setting temperature be 26 degree.
Step S5: judge that whether the temperature of power accumulator air inlet is higher than above-mentioned target temperature, as otherwise perform step S61, in this way then perform step S62.
Step S61: make the battery air door of air-conditioner air outlet rotate to the warm braw side made in crew module and air-conditioner air outlet (side that namely temperature is higher) for the larger position of the aperture (i.e. ventilation quantity) of power accumulator air inlet, enter step S4 afterwards.
Step S62: make the battery air door of air-conditioner air outlet rotate to the cold wind side made in crew module and air-conditioner air outlet (side that namely temperature is lower) for the larger position of the aperture of power accumulator air inlet, enter step S4 afterwards.
Can change equably under the effect of battery thermal management method of the present invention to make the temperature of power accumulator, above-mentioned steps S61 can comprise further: if the temperature of power accumulator air inlet is more lower than target temperature, then make the battery air door of air-conditioner air outlet rotate to the warm braw side made in crew module and air-conditioner air outlet for the position that the aperture of power accumulator air inlet is larger.At this, can according to the minimum temperature of the usual using state estimated driving force storage battery air inlet of power accumulator, to determine the maximum temperature difference with target temperature, the corresponding relation of temperature range and aperture can be preset like this according to the condition that the aperture of warm braw side corresponding to maximum temperature difference is maximum.
In like manner, above-mentioned steps S62 can comprise further: if the temperature of power accumulator air inlet is more higher than target temperature, then make the battery air door of air-conditioner air outlet rotate to the cold wind side made in crew module and air-conditioner air outlet for the position that the aperture of power accumulator air inlet is larger.At this, can according to the maximum temperature of the usual using state estimated driving force storage battery air inlet of power accumulator, to determine the maximum temperature difference with target temperature, the corresponding relation of temperature range and aperture can be preset like this according to the condition that the aperture of cold wind side corresponding to maximum temperature difference is maximum.
