[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] The present application discloses an air conditioner power adjustment method, a flow chart of which is shown as Figure 1 including:

[0048] Step S11, determining whether the air conditioner and / or power battery of the new energy vehicle is in a specific state;

[0049] Step S12, if it is determined that the air conditioner and / or power battery of the new energy vehicle is in a specific state, obtaining the power information of the power battery, the environmental temperature information and the available power of the whole vehicle in the new energy vehicle;

[0050] Step S13, adjusting the available power of the air conditioner in the new energy vehicle based on at least one of the power information of the power battery, the environmental temperature information and the available power of the whole vehicle.

[0051] The available power of the air conditioner in the new energy vehicle is usually not adjustable or cannot be automatically adjusted, which is prone to cause the new energy vehicle to be insufficient in power when the power battery in the new energy vehicle has a low power level and the air conditioner is still in operation, and the operation of the air conditioner consumes the power of the power battery, thereby causing the new energy vehicle to be insufficient in power.

[0052] Or, when the new energy vehicle is in a charging state, if the air conditioner is in operation at this time, the charging efficiency may be reduced.

[0053] In order to avoid the above situations, in the present scheme, it is determined whether the air conditioner and / or the power battery of the new energy vehicle is in a specific state, and when it is determined that the air conditioner and / or the power battery is in a specific state, the available power of the air conditioner in the vehicle is adjusted based on the power level information of the power battery, the environmental temperature information and the available power of the vehicle.

[0054] The air conditioner and / or the power battery of the new energy vehicle in a specific state can be that the new energy vehicle is in an air conditioner operation state, or the power level of the power battery in the new energy vehicle is lower than a certain specific threshold, or the power level of the power battery in the new energy vehicle is lower than a certain specific threshold and the air conditioner is in operation, or the power battery of the new energy vehicle is in a charging state, etc.

[0055] No matter which state the new energy vehicle is in, the power consumption of the power battery in the vehicle needs to be monitored to avoid the power consumption of the power battery being too large due to the operation of the air conditioner, thereby affecting the power of the vehicle.

[0056] Therefore, as long as it is determined that the air conditioner and / or the power battery of the new energy vehicle is in a specific state, the power level information of the power battery, the environmental temperature information and the available power of the vehicle are obtained, and the available power of the air conditioner is adjusted based on these information.

[0057] Among them, the power level information of the power battery and the available power of the vehicle can affect the power of the vehicle, if the power level information of the power battery is low or the available power of the vehicle is low, the power of the vehicle will decrease, or even the vehicle cannot be started; the environmental temperature information can affect the charging efficiency of the vehicle, if the environmental temperature is low, the charging efficiency of the power battery in the vehicle will decrease.

[0058] Since the power level information of the power battery, the environmental temperature information and the available power of the vehicle can affect the power or the charging efficiency of the vehicle, the available power of the air conditioner can be adjusted based on these parameters to ensure the power and the charging efficiency of the vehicle when the air conditioner is in operation.

[0059] For example, if the battery power information is sufficient, a higher available power can be set for the air conditioner, if the battery power information is low, the available power of the air conditioner needs to be appropriately reduced, if the vehicle available power is high, the available power of the air conditioner can be appropriately increased, etc.

[0060] The air conditioner power adjustment method disclosed in the embodiment determines whether the air conditioner and / or the power battery of the new energy vehicle is in a specific state; if it is determined that the air conditioner and / or the power battery of the new energy vehicle is in a specific state, the power information of the power battery, the environmental temperature information and the vehicle available power in the new energy vehicle are obtained; and the available power of the air conditioner in the new energy vehicle is adjusted based on at least one of the power information of the power battery, the environmental temperature information and the vehicle available power. The scheme can adjust the available power of the air conditioner in the vehicle by determining the state of the new energy vehicle, and when the vehicle is in a specific state, the available power of the air conditioner in the vehicle is in an adjustable state, avoiding the situation that the vehicle power is insufficient when the output capacity of the vehicle power battery is low.

[0061] Further, the available power of the air conditioner in the new energy vehicle is adjusted based on at least one of the power information of the power battery, the environmental temperature information and the vehicle available power, comprising:

[0062] The working state of the air conditioner in the new energy vehicle is determined; if it is determined that the air conditioner is in a compressor refrigeration state, the available power of the air conditioner is adjusted by adjusting the available power of the compressor; if it is determined that the air conditioner is in a thermistor heating state, the available power of the thermistor is adjusted based on the power information of the power battery, the environmental temperature information and the vehicle available power, to realize the adjustment of the available power of the air conditioner.

[0063] The working state of the air conditioner is determined, so as to determine whether the device currently consuming power in the air conditioner is a compressor or a thermistor.

[0064] If the air conditioner is in a refrigeration state, it is a compressor refrigeration, and the available power of the compressor needs to be adjusted to achieve the purpose of adjusting the available power of the air conditioner;

[0065] If the air conditioner is in a heating state, it may be engine heating or PTC thermistor heating. Specifically, when the engine water temperature is high and does not affect the efficiency of the engine itself, the air conditioner pipeline is connected with the engine pipeline, and the air conditioner heating is realized by using the waste heat of the engine; and in other cases, if the air conditioner needs to be heated, the PTC thermistor converts electrical energy into heat energy, so as to achieve the purpose of air conditioner heating.

[0066] Therefore, when it is determined that the air conditioner is in the heating state, it is further determined whether the air conditioner is in the engine heating state or the thermistor heating state. If the air conditioner is in the engine heating state, the waste heat of the engine is used for heating, and the power of the power battery in the vehicle is not affected. In this case, the available power of the air conditioner does not need to be adjusted. If the air conditioner is in the thermistor heating state, the available power of the thermistor needs to be adjusted based on the obtained power information of the power battery, the environmental temperature information and the available power of the vehicle, so as to achieve the purpose of adjusting the available power of the air conditioner.

[0067] The embodiment discloses an air conditioner power adjustment method, a flowchart of which is shown in Figure 2 as follows, comprising:

[0068] Step S21, determining the charging state of the power battery in the new energy vehicle and the use state of the thermistor.

[0069] Step S22, determining that the air conditioner and / or the power battery of the new energy vehicle are in a specific state based on the charging state of the power battery and the use state of the thermistor. In the specific state, the power information of the power battery, the environmental temperature information and the available power of the vehicle are obtained.

[0070] Step S23, determining whether the power battery is in a battery heating mode based on the environmental temperature information.

[0071] Step S24, adjusting the available power of the air conditioner based on the available power of the vehicle if it is determined that the power battery is in the battery heating mode.

[0072] If the battery power of the new energy vehicle is low, or the environmental temperature is low, if the power battery of the new energy vehicle is being charged at the charging pile at the same time, and the air conditioner of the vehicle is in the heating state, the charging current of the power battery may be small, and the current consumed by the thermistor of the air conditioner may be large, for example, the current consumed by the thermistor of the air conditioner is greater than or close to the charging current of the power battery. In this case, the power of the power battery may become less and less, or the charging power may rise slowly, which may cause the problem of insufficient power of the vehicle or low charging efficiency.

[0073] In this case, the air conditioner and / or the power battery of the new energy vehicle are in a specific state, which may be specifically that the vehicle is being charged, and the air conditioner is in the thermistor heating state. When the vehicle is in this state, the problem of insufficient power of the vehicle or low charging efficiency may occur. Therefore, it is necessary to first determine whether the air conditioner and / or the power battery of the vehicle are currently in this specific state. If the vehicle is in this specific state, the subsequent process is continued. If the vehicle is not in this specific state, the subsequent process does not need to be executed.

[0074] The state of charge of the power battery in the vehicle can indicate whether the power battery in the vehicle is currently in a charging state or an uncharged state; and the use state of the thermistor can indicate whether the air conditioner in the vehicle is currently in a thermistor heating state or not in the thermistor heating state.

[0075] Only when the power battery in the vehicle is in a charging state and the air conditioner is in a thermistor heating state, it can be determined that the vehicle is currently in the specific state; if the power battery in the vehicle is in a charging state and the air conditioner is not in a thermistor heating state, it cannot be determined that the vehicle is in the specific state; if the power battery in the vehicle is in an uncharged state and the air conditioner is in a thermistor heating state, it cannot be determined that the vehicle is in the specific state.

[0076] The battery heating mode is that the power battery cannot be charged at a specific ambient temperature, and the power battery of the vehicle needs to be heated first, and when the temperature of the power battery increases and reaches a certain threshold, the power battery can be charged. The state of heating the power battery is the battery heating mode. The specific ambient temperature is, for example, an ambient temperature lower than minus 20 degrees Celsius.

[0077] When it is determined based on the ambient temperature information that the power battery is currently in the battery heating mode, at this time, even if the power battery is in a charging mode, charging cannot be achieved, and therefore, the power in the power battery needs to be controlled to control the air conditioner to be in a thermistor heating mode, and the power battery is heated through the heating mode of the thermistor to increase the temperature of the power battery.

[0078] If the thermistor is heated based on the power in the power battery, the available power of the air conditioner, i.e., the available power of the thermistor, can be directly determined based on the available power of the whole vehicle. The available power of the whole vehicle is the actual available power of the vehicle minus the consumption power of the power conversion device, minus the loss power of the line, and minus the reserved power.

[0079] For different types of power batteries, the determination method of the available power of the thermistor is different.

[0080] Specifically, the battery type of the power battery is determined, if it is determined that the power battery is a liquid-cooled battery, the available power of the whole vehicle is directly determined as the available power of the thermistor; if the power battery is a direct-cooled battery, the available power of the thermistor is determined based on the difference between the available power of the whole vehicle and the consumption power of the heating structure for heating the direct-cooled battery.

[0081] If it is determined that the power battery is a liquid-cooled battery, the power battery is directly cooled or heated through the pipeline. If it is in a battery heating mode, only the power battery needs to supply power to the thermistor so that the thermistor can heat the liquid-cooled battery. After the temperature of the liquid-cooled battery rises to a certain threshold, the liquid-cooled battery can be charged through the charging pile. At this time, only the thermistor is in working condition. At this time, the available power of the thermistor is not limited, and the available power of the vehicle can be directly determined as the available power of the thermistor, so that the efficiency of the thermistor heating the power battery is improved, thereby charging the power battery as soon as possible.

[0082] If it is determined that the power battery is a direct-cooled battery, since the direct-cooled battery needs to be heated by a heating film, the air conditioner needs to be in a thermistor heating state due to the specific state of the vehicle. At the same time, when the power battery is in a battery heating mode, the power battery needs to supply power to the heating film so that the temperature of the direct-cooled battery can be charged through the charging pile after rising to a certain threshold. Therefore, the power battery not only needs to supply power to the thermistor, but also needs to supply power to the heating structure that can heat the direct-cooled battery. At this time, the available power of the thermistor needs to be limited, and the available power of the thermistor provided by the power battery needs to be determined based on the consumption power of the heating structure, that is, the available power of the thermistor is equal to the difference between the available power of the vehicle and the consumption power of the heating structure.

[0083] Further, if the temperature of the power battery has reached a certain threshold after being heated by the thermistor or the heating structure, the power battery is charged through the charging pile. During the charging process of the power battery by the charging pile, the available power of the thermistor can be continuously adjusted based on the power information of the power battery and / or the available power of the vehicle.

[0084] The air conditioner power adjustment method disclosed in the embodiment determines the charging state of the power battery in the vehicle and the use state of the thermistor. Based on the charging state of the vehicle battery and the use state of the thermistor, it is determined that the vehicle is in a specific state. In the specific state, the power information of the power battery, the environmental temperature information and the available power of the vehicle are obtained. If it is determined that the power battery is in a battery heating mode based on the environmental temperature information, the available power of the thermistor is adjusted based on the available power of the vehicle. When the environmental temperature is low and the power battery of the vehicle is determined to be in a battery heating mode, the available power of the thermistor is adjusted based on the available power of the vehicle. The available power of the thermistor is adjusted based on the current state of the environment, avoiding the problem of insufficient power of the vehicle caused by continuing to heat the air conditioner in the conventional mode when the output power of the vehicle power battery is low, or reducing the charging efficiency of the vehicle battery.

[0085] The air conditioner power adjustment method disclosed in the embodiment has a flow chart as shown in Figure 3 The air conditioner power adjustment method disclosed in the embodiment has a flow chart as shown in

[0086] Step S31, determine whether the air conditioner and / or the power battery of the new energy vehicle is in a specific state;

[0087] Step S32, if it is determined that the air conditioner and / or the power battery of the new energy vehicle is in a specific state, obtain the power information of the power battery, the environmental temperature information and the available power of the whole vehicle;

[0088] Step S33, determine whether the power battery is in a fast charging mode based on the charging state of the power battery;

[0089] Step S34, if it is determined that the power battery is in a fast charging mode, adjust the available power of the thermistor based on the environmental temperature information.

[0090] Determine the charging state of the power battery in the vehicle, that is, determine whether the power battery in the vehicle is in a charging state or an uncharged state. After determining that the charging state of the power battery is in a charging state, it can be further determined based on the charging state that the current charging mode is in a fast charging mode or a slow charging mode.

[0091] The fast charging mode, that is, the fast charging mode. In the fast charging mode, the charging current of the charging pile for charging the power battery is large. At this time, if the thermistor is heated, the current provided for the thermistor can be directly limited, that is, the maximum available power that can be supported by the thermistor can be used for heating.

[0092] Or, the available power of the thermistor can also be adjusted based on the charging current for charging the power battery. Specifically, the charging power is determined based on the charging current for charging the power battery, and the available power of the thermistor is determined based on the charging power, that is, the charging power is greater than the available power of the thermistor, which avoids the situation that the power is less and less during the charging process of the power battery. Or, the difference between the charging power and the available power of the thermistor can also be greater than a specific value, so as to ensure the charging efficiency.

[0093] During the process of charging the power battery through the charging pile, if the charging pile supplies power to the thermistor, the current provided for the thermistor does not need to be limited, that is, the available power of the thermistor can be controlled to be the maximum available power that can be supported; if the power battery supplies power to the thermistor, the available power of the thermistor needs to be adjusted based on the charging current for charging the power battery, so that the available power of the thermistor is less than the charging power for charging the battery, so as to ensure the charging efficiency.

[0094] In addition, since the charging efficiency of the charging pile charging the power battery is related to the ambient temperature, the higher the ambient temperature, the higher the charging efficiency of the charging pile charging the power battery, and the lower the ambient temperature, the lower the charging efficiency of the charging pile charging the power battery, therefore, how to adjust the available power of the thermistor can also be determined based on the ambient temperature information.

[0095] Specifically, if the ambient temperature information is greater than the first threshold, the available power of the air conditioner is determined as a first power corresponding to a first gear, and the first gear is a gear with the maximum power among the power gears of the air conditioner; if the ambient temperature information is less than the first threshold, the available power of the thermistor is determined as a second power corresponding to a second gear based on at least the power information of the power battery, and the second power is less than the first power.

[0096] The first threshold is greater than the temperature threshold of the power battery in the battery heating mode, for example, if the temperature threshold of the power battery in the battery heating mode is minus 20 degrees Celsius, that is, when the ambient temperature is lower than minus 20 degrees Celsius, the power battery will be in the battery heating mode, and the first threshold is greater than minus 20 degrees Celsius, that is, it is necessary to ensure that the power battery is in a state capable of charging, and the available power of the thermistor is adjusted based on whether the ambient temperature information is greater than the first threshold.

[0097] If the ambient temperature information is greater than the first threshold, it indicates that the charging efficiency of the power battery will not be affected by the temperature, at this time, the charging efficiency of the power battery in the fast charging mode is higher, and the available power of the thermistor can be directly set to the maximum power it can withstand, that is, the first power, and the power of the thermistor can be set through the gear, when the available power of the thermistor is in the first gear, the available power of the thermistor is the first power, at this time, the available power of the thermistor is in the highest gear power it can withstand.

[0098] When the available power of the thermistor is in a non-first gear, the available power of the thermistor must be less than the first power. The thermistor can be set to different gears, and different gears correspond to different powers of the thermistor, and the gear corresponding to the first power is the gear with the maximum power among all the gears that the thermistor can adjust.

[0099] When the ambient temperature information is greater than the first threshold, the thermistor can be directly set to the gear with the maximum power, or the thermistor can also be set to the gear corresponding to other power based on user demand.

[0100] If the ambient temperature information is less than the first threshold, the charging efficiency of the battery will be affected, at this time, the charging current will be reduced, therefore, when adjusting the available power of the thermistor, it can be adjusted based on the power information of the power battery, or adjusted based on the charging power of the power battery, or adjusted based on both the power information and the charging power of the power battery.

[0101] The environment temperature information can be less than a temperature threshold when the power battery is in the battery heating mode, or between the first threshold and the temperature threshold when the power battery is in the battery heating mode.

[0102] If the environment temperature information is less than the temperature threshold when the power battery is in the battery heating mode, the thermistor or the heating structure needs to be powered first by the power of the power battery for the purpose of heating the power battery, which requires adjusting the available power of the thermistor based on the power information of the power battery. If the environment temperature information is between the first threshold and the temperature threshold when the power battery is in the battery heating mode, the charging pile can charge the power battery at this time, but the charging efficiency is low due to the low temperature. In order to ensure the charging efficiency, the thermistor or the heating structure can still be powered at this time for the purpose of heating the power battery, so as to improve the charging efficiency. At this time, the available power of the thermistor needs to be determined based on the power information of the power battery and the charging power of the power battery. If the environment temperature information is between the first threshold and the temperature threshold when the power battery is in the battery heating mode, the thermistor or the heating structure does not heat the power battery, and the available power of the thermistor can be directly determined based on the charging power of the power battery, or when the charging pile powers the thermistor, the available power of the thermistor is directly set to the highest gear.

[0103] The air conditioner power adjustment method disclosed in the embodiment determines whether the air conditioner and / or the power battery of the new energy vehicle is in a specific state. If it is determined that the air conditioner and / or the power battery of the new energy vehicle is in a specific state, the power information of the power battery, the environment temperature information and the available power of the whole vehicle are obtained. It is determined whether the power battery is in a fast charging mode based on the charging state of the power battery. If it is determined that the power battery is in a fast charging mode, the available power of the thermistor is determined based on the environment temperature information. The scheme adjusts the available power of the thermistor based on the environment temperature information when the power battery is in a fast charging mode, which realizes the adjustment of the available power of the thermistor based on the current state of the environment, avoids the problem of insufficient power of the whole vehicle caused by continuing to heat the air conditioner in the conventional mode when the output power of the power battery of the whole vehicle is low, or reduces the charging efficiency of the power battery of the whole vehicle.

[0104] The air conditioner power adjustment method disclosed in the embodiment has a flowchart as shown in Figure 4 The air conditioner power adjustment method disclosed in the embodiment has a flowchart as shown in

[0105] Step S41, determining whether the air conditioner and / or the power battery of the new energy vehicle is in a specific state.

[0107] Step S43, determining whether the power battery is in the fast charging mode based on the charging state of the power battery.

[0108] Step S44, if it is determined that the power battery is in the slow charging mode, adjusting the available power of the air conditioner based on the power information of the power battery and the available power of the whole vehicle.

[0109] In the slow charging mode, the charging current of the charging pile charging the power battery is small, and if the charging pile is to supply power to the thermistor at the same time, it may affect the charging efficiency. In order to avoid this situation, it is necessary to determine the power information of the power battery and the available power of the whole vehicle, and adjust the available power of the thermistor based on the available power of the whole vehicle and the power information of the power battery.

[0110] When the power battery is in the slow charging mode, there are two cases, one is that the power battery is in the slow charging mode and needs to be heated, and the other is that the power battery is in the slow charging mode and does not need to be heated.

[0111] If the power battery needs to be heated, at this time, the available power of the thermistor needs to be reduced, and the heating of the air conditioner needs to be at the lowest power, so as to avoid the situation that the power is less and less during charging.

[0112] Specifically, the power coefficient can be determined based on the power information of the power battery, and the available power of the thermistor can be determined based on the product of the available power of the whole vehicle and the power coefficient, so as to realize the adjustment of the available power of the air conditioner. The power coefficient is a parameter for restricting the available power of the thermistor, so as to avoid the situation that the power is less and less with the charging of the power battery. The power coefficient is related to the value of the power information of the power battery. If the power of the power battery is high, the power coefficient is large, and the available power of the thermistor is also large. If the power of the power battery is low, the power coefficient is small, and the available power of the thermistor is also small.

[0113] The power information of the power battery is the state of charge SOC of the power battery.

[0114] When determining the available power of the thermistor, it can be determined by querying the pre-set power gear table. Specifically, the power coefficient is determined by the power information of the power battery, and the product of the power coefficient and the available power of the whole vehicle can obtain a power value that can be provided to the thermistor. Based on the obtained power value that can be provided to the thermistor, the power gear table is queried to determine the gear to which the thermistor needs to be adjusted. When the thermistor works at this gear, the available power of the thermistor is corresponding to the gear, and the gear is determined based on the power information of the power battery and the available power of the whole vehicle. Therefore, the finally determined available power of the thermistor is determined based on the power information of the power battery and the available power of the whole vehicle.

[0115] When the power battery is in a certain state, the determination of the power battery's power information, the ambient temperature information and the available power information of the whole vehicle is continuously carried out, so as to dynamically adjust the available power of the thermistor. If it is determined that the current available power of the thermistor is high, the gear of the thermistor is lowered to reduce the available power of the thermistor, and if it is determined that the current available power of the thermistor is low, the gear of the thermistor can be appropriately increased to increase the available power of the thermistor.

[0116] In addition, if the power battery is in a slow charging mode, the power battery does not need to be heated, at this time, only the minimum power of the air conditioner needs to be ensured to run, that is, the battery does not need to be heated by the thermistor, and then the operation of the thermistor is only used for heating the air conditioner, and in the charging process of the power battery, the thermistor is ensured to run at the minimum power to ensure the charging efficiency of the power battery.

[0117] Specifically, in this case, the power coefficient can be determined based on the power information of the power battery, and the available power of the thermistor is determined based on the product of the available power of the whole vehicle and the power coefficient. The power coefficient is related to the value of the power information of the battery, if the power of the power battery is high, the power coefficient is large, and the available power of the thermistor is also large; if the power of the power battery is low, the power coefficient is small, and the available power of the thermistor is also small.

[0118] When the available power of the thermistor is determined in the current case, it can also be determined by querying the pre-set power gear table. Specifically, the power coefficient is determined by the power information of the power battery, and a power value that can be provided to the thermistor is obtained based on the product of the power coefficient and the available power of the whole vehicle, and the gear to which the thermistor needs to be adjusted is determined by querying the power gear table based on the obtained power value that can be provided to the thermistor, when the thermistor works at the gear, the available power of the thermistor is corresponding to the gear, and the gear is determined based on the power information of the power battery and the available power of the whole vehicle, therefore, the finally determined available power of the thermistor is determined based on the power information of the power battery and the available power of the whole vehicle.

[0119] The lower the gear of the thermistor is, the lower the available power of the thermistor is, and the higher the gear of the thermistor is, the higher the available power of the thermistor is.

[0120] If the available power of the vehicle is low, the power factor is high. Therefore, the calculated power supplied to the thermistor is less than, but close to, the available power, resulting in a lower thermistor rating. If the available power of the vehicle is higher than the available power when the thermistor is in a low rating, the power factor decreases. Again, the calculated power supplied to the thermistor is less than the available power, and the reserved power also increases. Therefore, the thermistor rating is higher, where the reserved power is the difference between the available power and the power supplied to the thermistor; the reserved power increases with the thermistor rating. If the available power of the vehicle is high, the power supplied to the thermistor will not exceed the maximum power, resulting in a higher thermistor rating.

[0121] The air conditioning power adjustment method disclosed in this embodiment determines whether the air conditioning and / or power battery of the new energy vehicle is in a specific state. If it is determined that the air conditioning and / or power battery of the new energy vehicle is in a specific state, the method obtains the power battery's charge information, ambient temperature information, and the vehicle's available power. If it is determined that the power battery is in slow charging mode based on the power battery's charging status, the method adjusts the available power of the air conditioning based on the power battery's charge information and the vehicle's available power. This solution adjusts the available power of the thermistor based on the power battery's charge information and the vehicle's available power when the power battery is in slow charging mode. This achieves adjustment of the thermistor's available power based on the vehicle's current state, avoiding the problem of insufficient vehicle power or reduced vehicle battery charging efficiency caused by continuing to supply heat to the air conditioning in the conventional mode when the vehicle's power battery output capacity is low.
