Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application discloses a method for adjusting the power of an air conditioner, the flow chart of which is shown in figure 1, comprising the following steps:
step S11, determining whether an air conditioner and/or a power battery of the new energy vehicle are in a specific state;
step S12, if the air conditioner and/or the power battery of the new energy vehicle are/is determined to be in a specific state, electric quantity information, environment temperature information and available power of the whole vehicle of the power battery in the new energy vehicle are obtained;
and step S13, adjusting the available power of the air conditioner in the new energy vehicle based on at least one of the electric quantity information, the environment temperature information and the available power of the whole vehicle of the power battery.
The available power of the air conditioner in the new energy vehicle is usually not adjustable, or cannot be automatically adjusted, so that when the electric quantity of the power battery in the new energy vehicle is low, if the air conditioner is still in an operation state, the operation of the air conditioner can cause certain consumption on the electric quantity of the power battery, and the condition of insufficient power of the new energy vehicle is caused;
alternatively, when the new energy vehicle is in a charged state, if the air conditioner is in an operating state at this time, there is a possibility that the charging efficiency is lowered.
In order to avoid the occurrence of the above situations, in the scheme, whether the air conditioner and/or the power battery of the new energy vehicle are in a specific state or not is judged, and when the air conditioner and/or the power battery of the new energy vehicle are in the specific state, the available power of the air conditioner in the vehicle is further regulated based on the electric quantity information, the environment temperature information and the available power of the whole vehicle.
The air conditioner and/or the power battery of the new energy vehicle are in a specific state and can be: the new energy vehicle is in an air-conditioning running state, or the electric quantity of a power battery in the new energy vehicle is lower than a certain specific threshold value, or the electric quantity of the power battery in the new energy vehicle is lower than a certain specific threshold value, and meanwhile, the air conditioner is in an running state; alternatively, the power battery of the new energy vehicle is in a charged state or the like.
No matter which state the new energy vehicle is in, the power consumption of the power battery in the vehicle needs to be monitored, so that the situation that the power consumption of the power battery is high due to the operation of an air conditioner, and the power of the whole vehicle is affected is avoided.
Therefore, as long as the air conditioner and/or the power battery of the new energy vehicle are/is determined to be in a specific state, the electric quantity information, the environment temperature information and the whole vehicle available power of the power battery in the new energy vehicle are obtained, and the available power of the air conditioner is adjusted based on the information.
The electric quantity information of the power battery and the available power of the whole vehicle can influence the power of the vehicle, and if the electric quantity information of the power battery is lower or the available power of the whole vehicle is lower, the power of the vehicle is reduced and even the vehicle cannot be started; the ambient temperature information can affect the charging efficiency of the vehicle, and if the ambient temperature is low, the charging efficiency of the power battery in the vehicle is reduced.
Because the parameters of the electric quantity information of the power battery, the environment temperature information and the available power of the whole vehicle can influence the power or the charging efficiency of the vehicle, the available power of the air conditioner can be adjusted based on the parameters, so that the power and the charging efficiency of the vehicle can be ensured under the condition that the air conditioner is in a running state.
For example: if the electric quantity information of the battery is sufficient, higher available power can be set for the air conditioner, and if the electric quantity information of the battery is low, the available power of the air conditioner needs to be properly reduced; if the available power of the whole vehicle is higher, the available power of the air conditioner and the like can be properly increased.
According to the air conditioner power adjustment method disclosed by the embodiment, whether an air conditioner and/or a power battery of a new energy vehicle are in a specific state or not is determined; if the air conditioner and/or the power battery of the new energy vehicle are in a specific state, acquiring electric quantity information, environment temperature information and available power of the whole vehicle of the power battery in the new energy vehicle; and adjusting the available power of the air conditioner in the new energy vehicle based on at least one of the electric quantity information, the environment temperature information and the available power of the whole vehicle of the power battery. According to the scheme, the state of the new energy vehicle is determined, and when the state is in the specific state, the available power of the air conditioner in the vehicle can be adjusted, so that the available power of the air conditioner in the vehicle is in the adjustable state, and the situation that the power of the whole vehicle is insufficient when the output capacity of the power battery of the whole vehicle is lower is avoided.
Further, adjusting the available power of the air conditioner in the new energy vehicle based on at least one of the power battery power information, the ambient temperature information and the available power of the whole vehicle comprises:
determining the working state of an air conditioner in the new energy vehicle; if the air conditioner is determined to be in the refrigerating state of the compressor, the available power of the air conditioner is adjusted by adjusting the available power of the compressor; and if the air conditioner is in the thermistor heating state, adjusting the available power of the thermistor based on the electric quantity information of the power battery, the ambient temperature information and the available power of the whole vehicle, so as to realize the adjustment of the available power of the air conditioner.
The operating state of the air conditioner is determined to determine whether a device currently performing power consumption in the air conditioner is a compressor or a thermistor.
If the air conditioner is in a refrigerating state, the air conditioner is used for refrigerating by a compressor, and the available power of the compressor needs to be adjusted so as to achieve the purpose of adjusting the available power of the air conditioner;
if the air conditioner is in a heating state, the engine may be heated at this time, and the PTC thermistor may be heated. Specifically, when the water temperature of the engine is high and the self efficiency of the engine is not affected, the air conditioner pipeline is connected with the engine pipeline, and air conditioner heating is realized by utilizing waste heat of the engine; in other cases, if the air conditioner needs to heat, the PTC thermistor converts electric energy into heat energy, so that the purpose of heating the air conditioner is achieved.
Therefore, when the air conditioner is in the heating state, whether the air conditioner is in the engine heating state or the thermistor heating state needs to be further determined, and if the air conditioner is in the engine heating state, the electric quantity of a power battery in the vehicle is not influenced due to the fact that the waste heat of the engine is utilized for heating, and at the moment, the available power of the air conditioner is not required to be adjusted; if the power battery is in a thermistor heating state, the available power of the thermistor needs to be adjusted based on the obtained electric quantity information of the power battery, the environment temperature information and the available power of the whole vehicle, so that the purpose of adjusting the available power of the air conditioner is achieved.
The embodiment discloses a method for adjusting power of an air conditioner, a flow chart of which is shown in fig. 2, comprising the following steps:
step S21, determining the charging state of a power battery and the use state of a thermistor in the new energy vehicle;
step S22, determining that an air conditioner of the new energy vehicle and/or the power battery is in a specific state based on the charging state of the power battery and the using state of the thermistor, and obtaining electric quantity information, environment temperature information and available power of the whole vehicle under the specific state;
step S23, determining whether the power battery is in a battery heating mode or not based on the environmental temperature information;
And step S24, if the power battery is determined to be in the battery heating mode, adjusting the available power of the air conditioner based on the available power of the whole vehicle.
If the battery power of the new energy vehicle is lower, or the environmental temperature is lower, if the charging pile charges the power battery of the new energy vehicle, and at the same time, the air conditioner of the vehicle is in a heating state, at this time, the charging current of the power battery may be smaller, and the current consumed by the air conditioner thermistor is larger, for example: the current consumed by the air conditioner thermistor is larger than or close to the charging current of the power battery, and at the moment, the situation that the more the power battery is charged, the less the charged power is, or the charged power is slowly increased, so that the situation that the power of the whole vehicle is insufficient or the charging efficiency is reduced is caused.
In this case, the air conditioner and/or the power battery of the new energy vehicle is in a specific state, which may be specifically: the vehicle is charged while the air conditioner is in a state where the thermistor supplies heat, and when the vehicle is in this state, there may be a problem in that the power of the whole vehicle is insufficient or the charging efficiency is lowered, and therefore, it is necessary to first determine whether the air conditioner and/or the power battery of the vehicle is currently in this specific state. If the vehicle is in the specific state, the execution of the subsequent flow is continued, and if the vehicle is not in the specific state, the subsequent flow is not required to be executed.
The state of charge of the power battery in the vehicle can indicate whether the power battery in the vehicle is currently in a state of charge or in an uncharged state; the use state of the thermistor can indicate whether the air conditioner in the vehicle is currently in the thermistor heat supply state or is not in the thermistor heat supply state.
Only when the power battery in the vehicle is in a state of being charged and at the same time, the air conditioner is in a state of supplying heat through the thermistor, it can be determined that the vehicle is currently in the specific state; if the power battery in the vehicle is in a state of being charged and the air conditioner is not in a state of heat supply by the thermistor, it cannot be determined that the vehicle is in the specific state; if the power battery is in an uncharged state and the air conditioner is in a state where the thermistor is heating, it cannot be determined that the vehicle is in the specific state.
The battery heating mode, that is, the power battery cannot be charged at a specific ambient temperature, needs to heat the power battery of the vehicle first, and can charge the power battery when the temperature of the power battery increases and reaches a certain threshold value, namely the battery heating mode is the state of heating the power battery. Specific ambient temperatures, such as: an ambient temperature below-20 degrees celsius.
When the power battery is currently in the battery heating mode based on the environmental temperature information, even if the power battery is in the charging mode, the charging cannot be realized, so that the electric quantity in the power battery is required to be used for controlling the air conditioner to be in the thermistor heating mode, and the power battery is heated through the thermistor heating mode, so that the purpose of increasing the temperature of the power battery is achieved.
If the thermistor consumes electricity based on the electricity in the power battery, and heat supply is realized through the thermistor, the available power of the air conditioner, namely 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 obtained by subtracting the consumed power of the power conversion device from the actual available power of the vehicle, subtracting the consumed power of a line and subtracting the reserved power.
The available power to the thermistor is determined differently for different types of power cells.
Specifically, determining the battery type of the power battery, and if the power battery is determined to be a liquid cooling battery, directly determining the available power of the whole vehicle as the available power of the thermistor; if the power battery is a direct-cooling battery, the available power of the thermistor is determined based on the difference between the available power of the whole vehicle and the consumed power of a heating structure for heating the direct-cooling battery.
If the power battery is determined to be a liquid cooling battery, the power battery is directly cooled or heated through a pipeline, if the power battery is in a battery heating mode, the power battery is only required to supply power to the thermistor, so that the thermistor can heat the liquid cooling battery, the liquid cooling battery can be charged through the charging pile after the temperature of the liquid cooling battery rises to a certain threshold value, at the moment, only the thermistor is in a working state, at the moment, the available power of the thermistor is not required to be limited, the available power of the whole vehicle can be directly determined to be the available power of the thermistor, so that the heat supply efficiency of the thermistor for the power battery is improved, and the power battery is charged as soon as possible.
If the power battery is determined to be a direct-cooling battery, the direct-cooling battery needs to be heated through the heating film, and then the air conditioner needs to be in a thermistor heating state because the vehicle is in a specific state; meanwhile, when the power battery is in a battery heating mode, the power battery is required to supply power for the heating film, so that the temperature of the direct-cooling battery can be charged through the charging pile after being increased to a certain threshold value. Therefore, the power battery not only needs to supply power to the thermistor, but also needs to supply power to the heating structure capable of heating the direct-cooling battery, at this time, a certain limitation needs to be performed on the available power of the thermistor, and then the available power that the power battery can provide for the thermistor needs to be determined based on the consumed power of the heating structure, namely: the available power of the thermistor is equal to the difference between the available power of the whole vehicle and the consumed power of the heating structure.
Further, if the temperature of the power battery is heated by the thermistor or the heating structure, and reaches a certain threshold, at this time, the power battery is charged by the charging pile, and the available power of the thermistor can be continuously adjusted based on the electric quantity information of the power battery and/or the available power of the whole vehicle in the process of charging the power battery by the charging pile.
The air conditioner power adjusting method disclosed by the embodiment determines the charging state of a power battery and the use state of a thermistor in a vehicle; determining that the vehicle is in a specific state based on the charging state of the vehicle battery and the use state of the thermistor, and obtaining electric quantity information, environment temperature information and available power of the whole vehicle under the specific state; and if the power battery is determined to be in a battery heating mode based on the environmental temperature information, adjusting the available power of the thermistor based on the available power of the whole vehicle. According to the scheme, when the ambient temperature is lower and the power battery of the vehicle is determined to be in the battery heating mode, the available power of the thermistor is adjusted based on the available power of the whole vehicle, so that the adjustment of the available power of the thermistor based on the current state of the environment is realized, and the problem that the whole vehicle power is insufficient or the charging efficiency of the whole vehicle battery is reduced due to the fact that the air conditioner is continuously supplied with heat according to the conventional mode when the output capacity of the whole vehicle power battery is lower is avoided.
The embodiment discloses a method for adjusting power of an air conditioner, a flow chart of which is shown in fig. 3, comprising the following steps:
step S31, determining whether an air conditioner and/or a power battery of the new energy vehicle are in a specific state;
step S32, if the air conditioner and/or the power battery of the new energy vehicle are/is determined to be in a specific state, electric quantity information, environment temperature information and available power of the whole vehicle of the power battery are obtained;
step S33, determining whether the power battery is in a fast charge mode or not based on the charge state of the power battery;
and step S34, if the power battery is determined to be in the quick charge mode, the available power of the thermistor is adjusted based on the environmental temperature information.
The determination of the state of charge of the power battery in the vehicle, i.e. whether the power battery in the vehicle is in a state of charge or in an uncharged state, after the determination of the state of charge of the power battery as being in a state of charge, it is also possible to determine the current charge mode, i.e. whether it is currently in a fast charge mode or in a slow charge mode, further based on the state of charge.
In the fast charging mode, because the charging current of the charging pile for charging the power battery is larger, if the thermistor is required to supply heat, the current supplied to the thermistor can be directly and not limited, and the heat can be supplied by the maximum available power supported by the thermistor;
Or, the available power of the thermistor can 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, namely, the situation that the more and less electric quantity is charged in the process of charging the power battery is avoided, and the available power of the thermistor is ensured to be larger than the available power of the thermistor; alternatively, it may be: the difference between the charging power and the available power of the thermistor is ensured to be larger than a specific value, so that the charging efficiency is ensured.
In the process of charging the power battery through the charging pile, if the charging pile is used for supplying power to the thermistor, the available power of the thermistor can be controlled to be the maximum available power which can be supported by the thermistor without limiting the current supplied to the thermistor; if the thermistor is powered by a power battery, 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 smaller than the charging power for charging the battery, thereby ensuring the charging efficiency.
In addition, because the charging efficiency of the charging pile for charging the power battery is related to the ambient temperature, the higher the ambient temperature is, the higher the charging efficiency of the charging pile for charging the power battery is, the lower the ambient temperature is, and the lower the charging efficiency of the charging pile for charging the power battery is, therefore, the available power of the thermistor can be further determined to be adjusted based on the ambient temperature information.
Specifically, if the environmental temperature information is greater than a first threshold value, determining that the available power of the air conditioner is first power corresponding to a first gear, wherein the first gear is the gear with the largest power in the power gears of the air conditioner; and if the environmental temperature information is smaller than the first threshold value, determining that the available power of the thermistor is second power corresponding to the second gear at least based on the electric quantity information of the power battery, wherein the second power is smaller than the first power.
The first threshold is greater than a temperature threshold of the power battery when in a battery heating mode, such as: if the temperature threshold value of the power battery in the battery heating mode is minus 20 ℃, namely when the ambient temperature is lower than minus 20 ℃, the power battery can be in the battery heating mode, and the first threshold value is higher than minus 20 ℃, namely the power battery is required to be in a chargeable state, and the available power of the thermistor is adjusted based on whether the ambient temperature information is higher than the first threshold value.
If the environmental temperature information is greater than the first threshold value, the charging efficiency of the power battery is not affected by temperature, the charging efficiency of the power battery in the quick charging mode is higher at the moment, the available power of the thermistor can be directly set to be the maximum power which can be born by the power battery, namely, the first power, the power of the thermistor can be set through the gear, and when the available power of the thermistor is in the first gear, the available power of the thermistor is the first power, and at the moment, the available power of the thermistor is in the power of the highest gear which can be born by the power battery.
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 provided with different gears, the different gears correspond to different powers of the thermistor, and the gear corresponding to the first power is the gear with the largest power in all gears which can be regulated by the thermistor.
When the environmental temperature information is greater than the first threshold value, the thermistor can be directly set to be in a gear with the maximum power, or the thermistor can be set to be in gears corresponding to other powers based on user requirements.
If the ambient temperature information is smaller than the first threshold value, the charging efficiency of the battery can be affected, at this time, the charging current can be reduced, and when the available power of the thermistor is adjusted, the adjustment can be performed based on the electric quantity information of the power battery, or the adjustment can be performed based on the charging power of the power battery, and the adjustment can also be performed based on the electric quantity information and the charging power of the power battery at the same time.
When the ambient temperature information is less than the first threshold, it may be less than the temperature threshold when the power battery is in the battery heating mode, or may be between the first threshold and the temperature threshold when the power battery is in the battery heating mode.
If the environmental temperature information is smaller than the temperature threshold value when the power battery is in the battery heating mode, the power is required to be supplied to the thermistor or the heating structure through the electric quantity of the power battery so as to achieve the purpose of heating the power battery, and the available power of the thermistor is required to be adjusted based on the electric quantity information of the power battery; if the environmental temperature information is between the first threshold value and the temperature threshold value when the power battery is in the battery heating mode, the charging pile can charge the power battery at the moment, and the charging efficiency is low only because of low temperature; if the environmental temperature information is between the first threshold value and the temperature threshold value when the power battery is in the battery heating mode, the power battery is not heated by the thermistor or the heating structure, the available power of the thermistor can be directly determined based on the charging power of the power battery, or when the power battery is supplied to the thermistor by the charging pile, the gear corresponding to the available power of the thermistor is directly set as the highest gear.
According to the air conditioner power adjustment method disclosed by the embodiment, whether an air conditioner and/or a power battery of a new energy vehicle are in a specific state or not is determined, and if the air conditioner and/or the power battery of the new energy vehicle are in the specific state, electric quantity information, environment temperature information and available power of the whole vehicle of the power battery are obtained; determining whether the power battery is in a fast charge mode based on a state of charge of the power battery; and if the power battery is determined to be in the fast charge mode, determining the available power of the thermistor based on the environmental temperature information. According to the scheme, under the condition that the power battery is in the fast charging mode, the available power of the thermistor is adjusted based on the environmental temperature information, the adjustment of the available power of the thermistor based on the current state of the environment is realized, and the problem that the whole vehicle power is insufficient or the charging efficiency of the whole vehicle battery is reduced due to the fact that the air conditioner is continuously supplied with heat according to the conventional mode when the output capacity of the whole vehicle power battery is low is avoided.
The embodiment discloses a method for adjusting power of an air conditioner, a flow chart of which is shown in fig. 4, comprising the following steps:
step S41, determining whether an air conditioner and/or a power battery of the new energy vehicle are in a specific state;
step S42, if the air conditioner and/or the power battery of the new energy vehicle are/is determined to be in a specific state, electric quantity information, environment temperature information and available power of the whole vehicle of the power battery are obtained;
Step S43, determining whether the power battery is in a fast charge mode or not based on the charge state of the power battery;
and S44, if the power battery is determined to be in the slow charge mode, adjusting the available power of the air conditioner based on the electric quantity information of the power battery and the available power of the whole vehicle.
In the slow charging mode, the charging current of the charging pile for charging the power battery is small, if the charging pile is to supply power to the thermistor at the same time, the charging efficiency may be affected, and in order to avoid the situation, the electric quantity information of the power battery and the available power of the whole vehicle need to be determined, and the available power of the thermistor is adjusted based on the available power of the whole vehicle and the electric quantity information of the power battery.
When the power battery is in the slow charge mode, two conditions are included, one is that the power battery is in the slow charge mode, and meanwhile the power battery needs to be heated, and the other is that the power battery is in the slow charge mode, and the power battery does not need to be heated.
If the power battery needs to be heated, the available power of the thermistor needs to be reduced at the moment, and the condition that the electric quantity is charged more and less in the charging process is avoided by ensuring that the heat supply of the air conditioner is at the lowest power.
Specifically, the power coefficient can be determined based on the electric quantity 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, so that the available power of the air conditioner is adjusted. The power coefficient is a parameter used for restraining the available power of the thermistor, so that the situation that the electric quantity is lower along with the charging of the power battery is avoided. The power coefficient is related to the value of the electric quantity information of the power battery, if the electric quantity of the power battery is higher, the power coefficient is larger, and the available power of the thermistor is correspondingly larger; if the power battery has lower electric quantity, the power coefficient is smaller, and the available power of the thermistor is correspondingly smaller.
The electric quantity information of the power battery is the state of charge (SOC) of the power battery.
When determining the available power of the thermistor, the available power can be determined by querying a preset power gear table. Specifically, the power coefficient is determined through the electric quantity information of the power battery, a power value which can be provided for the thermistor can be obtained based on the power coefficient which is the product of the electric quantity information of the power battery and the available power of the whole vehicle, the gear to which the thermistor needs to be adjusted can be determined based on the obtained power value which can be provided for the thermistor and the query power gear table, when the thermistor works under the gear, the available power of the thermistor corresponds to the gear, and the gear is determined based on the electric quantity information of the power battery and the available power of the whole vehicle, so that the finally determined available power of the thermistor is determined based on the electric quantity information of the power battery and the available power of the whole vehicle.
When the power battery is in a specific state, the electric quantity information, the environment temperature information and the whole vehicle available power information of the power battery are continuously determined, so that the available power of the thermistor is dynamically adjusted. If the available power of the current thermistor is determined to be higher, the gear of the thermistor is reduced to reduce the available power of the thermistor, and if the available power of the current thermistor is determined to be lower, the gear of the thermistor can be properly increased to increase the available power of the thermistor.
In addition, if the power battery is in the slow charge mode, the power battery does not need to be heated, and at the moment, only the lowest power operation of the air conditioner is required to be ensured, namely, the battery is not required to be heated through 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 operation of the thermistor with the lowest power is ensured, so that the charging efficiency of the power battery is ensured.
Specifically, in this case, the power coefficient may be determined based on the electric quantity information of the power battery, and the available power of the thermistor may be determined based on the product of the available power of the entire vehicle and the power coefficient. The power coefficient is related to the value of the electric quantity information of the battery, if the electric quantity of the power battery is higher, the power coefficient is larger, and the available power of the thermistor is correspondingly larger; if the power battery has lower electric quantity, the power coefficient is smaller, and the available power of the thermistor is correspondingly smaller.
When determining the available power of the thermistor in the present case, it can also be determined by looking up a preset power shift table. Specifically, the power coefficient is determined through the electric quantity information of the power battery, a power value which can be provided for the thermistor can be obtained based on the power coefficient which is the product of the electric quantity information of the power battery and the available power of the whole vehicle, the gear to which the thermistor needs to be adjusted can be determined based on the obtained power value which can be provided for the thermistor and the query power gear table, when the thermistor works under the gear, the available power of the thermistor corresponds to the gear, and the gear is determined based on the electric quantity information of the power battery and the available power of the whole vehicle, so that the finally determined available power of the thermistor is determined based on the electric quantity information of the power battery and the available power of the whole vehicle.
The lower the gear the thermistor is in, the lower the available power is, and the higher the gear the thermistor is in, the higher the available power is.
If the value of the available power of the whole vehicle is lower, at the moment, the power coefficient is larger, then the calculated power value which can be provided for the thermistor is smaller than the value of the available power of the whole vehicle, but is close to the value of the available power of the whole vehicle, and the gear of the thermistor which is finally determined is also lower; if the value of the available power of the whole vehicle is increased relative to the value of the available power of the whole vehicle when the thermistor is in a low gear, at this time, the power coefficient is reduced, then the calculated power value which can be provided for the thermistor is smaller than the value of the available power of the whole vehicle, and the value of the reserved power is also increased, and the gear where the thermistor is finally determined is increased, wherein the reserved power is the difference obtained by subtracting the power value which can be provided for the thermistor from the value of the available power of the whole vehicle, namely, the value of the reserved power is increased along with the increase of the gear where the thermistor is located; if the available power of the whole vehicle is higher, at the moment, the power value which can be provided for the thermistor can be directly determined not to exceed the maximum power value, and correspondingly, the gear of the finally determined thermistor is also higher.
