Then, it is determined whether or not the factor specified by the improvement of the user's vehicle usage method can be dealt with. Then, when it is determined that the specified factor can be dealt with, the specific factor advice information predetermined as advice for improving the vehicle usage method of the user corresponding to the specified factor is to be notified When it is determined that the specified factor cannot be dealt with, the specific factor advice information is not set as information to be notified. In other words, when it is determined that the factor specified as the deterioration of the secondary battery progresses due to the improvement of the user's vehicle usage method, the specific factor advice information is notified to the user. On the other hand, when it is determined that the factor specified as the secondary battery deterioration progresses due to the improvement of the user's vehicle usage method, the specific factor advice information is not notified to the user. Thereby, the information advised in order to suppress the deterioration of the secondary battery can be notified more appropriately. Here, in the “secondary battery state”, the temperature, voltage, charge / discharge power, charge / discharge current, charge amount (or charge ratio that is the ratio of charge amount to capacity) of the secondary battery is not charged / discharged. Time etc. are included.

  In such an information notification system of the present invention, when the factor determination unit is specified as a factor by which the duration of the predetermined high-temperature state of the secondary battery progresses as the factor of deterioration of the secondary battery by the factor specifying unit, When it is determined that the temperature or the amount of solar radiation obtained from the meteorological data for the period required for the identification is equal to or higher than a predetermined temperature threshold or the amount of solar radiation threshold, the above-mentioned specification is made by improving the user's vehicle usage method.

It can also be a means for determining that it is not possible. In this way, the secondary battery deteriorates due to the frequency of the secondary battery's low voltage state, high voltage state, high discharge power state, and high charge power state due to slips and grips on snowy roads and icy roads. When it is specified as a factor to be specified, the specific factor advice information may not be notified to the user.

It is possible not to notify the user. In this case, the vehicle may be equipped with an engine that outputs driving power.

  Alternatively, in the information notification system according to the present invention, the factor specifying unit is configured such that a time during which the temperature of the secondary battery is equal to or higher than a predetermined temperature threshold is predetermined for the same area and the same vehicle type as the vehicle. When it is determined that the temperature is higher than the allowable high temperature time, it may be a means for specifying the duration of the secondary battery in a predetermined high temperature state as a factor that causes deterioration of the secondary battery. Further, the factor specifying means is configured such that the frequency at which the voltage of the secondary battery is equal to or lower than a predetermined discharge-side voltage threshold is equal to or higher than a predetermined low voltage allowable frequency for the same area and the same vehicle type as the vehicle. When determined, it may be a means for specifying the frequency at which the secondary battery is in a predetermined low voltage state as a factor that causes deterioration of the secondary battery. Further, the factor specifying means is configured such that the frequency at which the voltage of the secondary battery is equal to or higher than a predetermined charging side voltage threshold is equal to or higher than a predetermined high voltage allowable frequency for the same area and the same vehicle type as the vehicle. When the determination is made, it may be a means for specifying the frequency at which the secondary battery is in a predetermined high voltage state as a factor that causes deterioration of the secondary battery. Alternatively, the factor specifying means may determine that the frequency at which the discharge power of the secondary battery is equal to or greater than a predetermined discharge-side power threshold is a high discharge power allowable frequency that is predetermined for the same area and the same vehicle type as the vehicle. When it is determined as described above, it may be a means for specifying the frequency at which the secondary battery is in a predetermined high discharge power state as a factor that causes deterioration of the secondary battery. In addition, the factor specifying means is configured to allow a high charging power permissible predetermined frequency for the same area and the same vehicle model as the vehicle so that the charging power of the secondary battery is equal to or higher than a predetermined charging power threshold. When it is determined that the frequency is equal to or higher than the frequency, the frequency at which the secondary battery is in a predetermined high charge power state may be specified as a factor that causes deterioration of the secondary battery.

It is obtained by dividing the number of times that the storage ratio of the secondary battery when the later time elapses is equal to or greater than a predetermined storage ratio threshold as a ratio close to full charge by the number of times the secondary battery is fully charged. When it is determined that the full charge leaving frequency ratio is equal to or greater than a predetermined full charge leaving frequency ratio threshold, the duration of the state where the secondary battery is close to full charge is a factor that causes deterioration of the secondary battery. The secondary battery is not charged / discharged after elapse of a predetermined determination time from the start of use of the secondary battery. Said two out of time When it is determined that the full charge leaving time ratio, which is the ratio of the time when the power storage ratio of the battery is close to the full charge, is equal to or higher than a predetermined power storage ratio threshold, is equal to or higher than the predetermined full charge left time ratio threshold In addition, it may be a means for specifying the duration of the state in which the secondary battery is almost fully charged as a factor that causes deterioration of the secondary battery.

These processes are executed by the server ECU 74 by reading out necessary software and data from the HDD 72, and are shown in the functional block of FIG. 1 showing the functions realized by the hardware or software of the electronic control unit 74 or a combination thereof. In addition, the factor specifying unit 74a, the factor determining unit 74b, the notification information setting unit 74c, and the notification processing unit 74d of the server ECU 74 perform factor specifying processing, factor determination processing, notification information setting processing, and notification processing, respectively.

  Next, the operation of the information notification system 10 according to the embodiment, particularly, the operation when notifying the user of the vehicle in order to suppress the deterioration of the battery 50 mounted on the vehicle 20 will be described. FIG. 3 is a flowchart showing an example of a factor specifying process routine executed by the server ECU 74 of the server 70. This routine is executed when a signal indicating that the traveling of the vehicle 20 is finished and the system is stopped is received from the HVECU 60 of the vehicle 20 (that is, every one trip).

  When the factor specifying process routine is executed, the CPU 75 of the server ECU 74 first starts the vehicle 20 during the period from when the system is started to stop when the vehicle 20 starts running (that is, during one trip). Data (that is, sampling data) at predetermined sampling times (for example, every tens of milliseconds, every hundreds of milliseconds, every few seconds, etc.) of the battery temperature Tb, the battery voltage Vbj, and the storage rate SOC of the battery 50 mounted in Are input as battery temperature Tb (i), battery voltage Vbj (i), and storage rate SOC (i) (where i is an integer of 1 or more that is incremented at each sampling), and the battery 50 is fully charged before the start of traveling. A full charge execution flag F indicating whether or not the battery has been charged; Non-charging / discharging time Tond, which is the duration of the state in which the battery 50 is not charged / discharged, full charging, which is the elapsed time from when the battery 50 is fully charged before the start of running until when the battery 50 starts discharging A process of inputting data necessary for the process such as the leaving time Tcnd and the use accumulated time Tuse that is an elapsed time from the start of use of the battery 50 (when the vehicle 20 is shipped) is executed (step S100).

  Here, the battery temperature Tb (i), the battery voltage Vbj (i), and the storage rate SOC (i) are respectively detected by a temperature sensor attached to the battery 50, and the plurality of battery cells constituting the battery 50 are What is detected by the voltage sensors attached to each of them, and what is calculated based on the integrated value of the charging / discharging current Ib detected by the current sensor, are obtained from the battery ECU 52 at predetermined sampling times during the traveling of the vehicle 20. The data input by communication is stored in a flash memory (not shown) of the HVECU 60, and the stored data is input by communication via the network 19. Further, the full charge execution flag F is set (set) when the battery 50 is fully charged by using the power from the external power source 58 by driving the charger 54 before the vehicle 20 starts traveling. This flag is a flag that is set (reset) to 0 after being transmitted to the server 70 when the system is stopped. The flag set by the HVECU 60 is input via communication via the network 19. The non-charging / discharging time Tond is the time elapsed from when the system was last stopped (when the previous trip immediately before the current trip was completed) until the system was started to start running. The time counted by a timer (not shown) of the HVECU 60 as the time excluding the time required for the battery 50 to be charged by the electric power from the external power source 58 (value 0 when charging is not performed) The input is made via communication via the network 19. When the full charge execution flag F is a value 1, the full charge leaving time Tcnd is a ratio SOCf (for example, the charge rate SOC of the battery 50 corresponding to full charge from when the battery 50 is fully charged before the start of traveling) (for example, 80%, 82%, etc.) until a threshold threshold value Sref (for example, 78%, 79%, etc.) determined in advance as an experiment as a value indicating a state in which discharge is started for driving or auxiliary equipment. The time measured by a timer (not shown) of the HVECU 60 is input by communication via the network 19. As the accumulated usage time Tuse of the battery 50, the time measured by a timer (not shown) of the HVECU 60 is inputted by communication via the network 19.

  When the data is input in this way, the high temperature state integrated time Ttb which is an integrated value of the time when the battery temperature Tb of the battery 50 is equal to or higher than a temperature threshold value Tbref predetermined based on the characteristics of the battery 50 as the lower limit value of the range indicating the high temperature state. Is updated and stored in a predetermined area of the HDD 72 (step S110). In the embodiment, the high temperature state integration time Ttb is set (set) as an initial value in a predetermined area of the HDD 72 when the vehicle 20 is newly registered in the HDD 72 so that the data of the vehicle 20 can be handled at the time of shipment. Thereafter, the value calculated based on the battery temperature Tb (i) input as the sampling data for each run in the process of step S100 is updated by adding (integrating) the value calculated to the value stored in the HDD 72. It was.

  Subsequently, the battery voltage Vbj of each battery cell of the battery 50 becomes equal to or higher than a charging side voltage threshold value Vbref1 (for example, several V) determined in advance based on the characteristics of the battery 50 as the lower limit value of the range indicating the high voltage state. The number of high voltage states Cvhj (subscript j is the same as battery voltage Vbj) is updated and stored in a predetermined area of HDD 72 (step S120). In the embodiment, when the data of the vehicle 20 is newly registered in the HDD 72, the high voltage state number Cvhj is set (set) as an initial value in a predetermined area of the HDD 72, and then the step S100 is performed. Based on the battery temperature Vbj (i) input as sampling data for each run by the process of (for example, by counting the number of times Vbj (i) ≧ Vbref1 and Vbj (i−1) <Vbref1) The product is updated by adding (accumulating) the value stored in the HDD 72.

  Furthermore, the discharge side voltage threshold Vbref2 (for example, about 1V from the charge side voltage threshold Vbref1) that is predetermined based on the characteristics of the battery 50 as the lower limit value of the range in which the battery voltage Vbj of each battery cell of the battery 50 indicates the low voltage state. The low voltage state count Cvlj (subscript j is the same as the battery voltage Vbj) is updated and stored in a predetermined area of the HDD 72 (step S130). In the embodiment, the low voltage state frequency Cvlj is set (set) as a default value 0 in a predetermined area of the HDD 72 when data of the vehicle 20 is newly registered in the HDD 72 at the time of shipment of the vehicle. Based on the battery temperature Vbj (i) input as sampling data for each run by the process of (for example, by counting the number of times Vbj (i) ≦ Vbref2 and Vbj (i−1)> Vbref2) The product is updated by adding (accumulating) the value stored in the HDD 72.

  Next, the full charge count Ccs, which is the number of times the battery 50 is fully charged, is updated and stored in a predetermined area of the HDD 72, and at the same time after the battery 50 is fully charged (for example, 6 hours) Or a predetermined area of the HDD 72 by updating the full charge leaving count Ccn, which is the number of times that the storage ratio SOC of the battery 50 is equal to or greater than the above-described ratio threshold value Sref that is close to full charge. (Step S140). In the embodiment, the full charge count Ccs is set (set) as an initial value in a predetermined area of the HDD 72 when data of the vehicle 20 is newly registered in the HDD 72 at the time of shipment of the vehicle. When the full charge execution flag F having a value of 1 is input by the processing, the value stored in the HDD 72 is incremented to be updated. Further, in the embodiment, the full charge leaving count Ccn is set (set) as a default value 0 in a predetermined area of the HDD 72 when data of the vehicle 20 is newly registered in the HDD 72 at the time of shipment of the vehicle. When it is determined that the value should be incremented based on the power storage ratio SOC (i) input as sampling data for each run in the process of step S100, the value stored in the HDD 72 is incremented to be updated.

  Further, the non-charge / discharge integrated time Ton, which is an integrated value after the start of use of the battery 50 (during shipment of the vehicle 20) in a state in which the battery 50 is not charged / discharged, is updated and stored in a predetermined area of the HDD 72. At the same time, the battery 50 is fully discharged after the start of use of the battery 50 (when the vehicle 20 is shipped) from the time when the battery 50 is fully charged before the start of traveling until the time when the battery 50 starts discharging. The accumulated time Tcn is updated and stored in a predetermined area of the HDD 72 (step S150). In the embodiment, the non-charging / discharging integration time Ton and the full charge leaving integration time Tcn are set to 0 as initial values in a predetermined area of the HDD 72 when data of the vehicle 20 is newly registered in the HDD 72 when the vehicle is shipped ( After that, the non-charge / discharge integration time Ton is calculated by integrating the input non-charge / discharge time Tod regardless of the value of the full charge execution flag F input by the process of step S100, and the full charge neglect integration is performed. The time Tcn is calculated by accumulating the full charge leaving time Tcnd input when the full charge execution flag F input by the process of step S100 is 1, and is updated and stored.

  In the embodiment, the battery temperature Tb (i), the battery voltage Vbj (i), and the storage ratio SOC (i) as sampling data (time series data) are not stored in the HDD 72 of the server 70 as they are, but are stored in the battery temperature Tb ( high temperature state integration time Ttb based on i), high voltage state frequency Cvhj and low voltage state frequency Cvlj based on battery voltage Vbj (i), full charge storage frequency Ccn and full charge storage integration time Tcn based on power storage ratio SOC (i). Since the data is converted into statistical data and stored in the HDD 72 of the server 70, the storage area of the HDD 72 can be effectively used while saving (saving) the storage area of the HDD 72. FIG. 4 shows an example of the relationship between the time from the start of traveling of the vehicle 20 and the battery voltage Vbj (i) of the battery cell of the battery 50. In the illustrated example, the number of times that the battery voltage Vbj (i) is equal to or higher than the charging side voltage threshold Vbref1 and the number of times that is equal to or lower than the discharging side voltage threshold Vbref2 is smaller than the number of samplings. It can be seen that it can be suppressed (saved).

  In this way, the high temperature state integration time Ttb of the battery 50, the number of high voltage states Cvhj of each battery cell of the battery 50, the number of low voltage states Cvlj of each battery cell of the battery 50, the number of full charge Ccs of the battery 50, and the battery 50 being left fully charged. When the number of times Ccn, the non-charge / discharge integrated time Ton of the battery 50, and the full charge storage integrated time Tcn of the battery 50 are updated and stored, the input accumulated use time Tuse of the battery 50 and the factors that cause deterioration of the battery 50 are specified. Specific time Tdet (for example, several weeks or several hours) determined in advance as a time required for the measurement (a time required for collecting sufficient data by monitoring the state of the battery 50 and specifying the deterioration factor of the battery 50) Month etc.) (step S160), and the accumulated usage time Tuse of the battery 50 is the specific time Tde. At the time of less than, the routine ends.

  When the accumulated use time Tuse of the battery 50 is equal to or greater than the specific time Tdet, it is determined that sufficient data has been collected to identify the deterioration factor of the battery 50 by monitoring (monitoring) the state of the battery 50. It is determined whether or not the state integration time Ttb is equal to or greater than a predetermined high temperature allowable time Ttbref (step S170). When the high temperature state integration time Ttb is equal to or higher than the high temperature allowable time Ttbref, the duration time of the battery 50 in the high temperature state is determined. A long time (that is, a high temperature factor) is specified as a factor that causes deterioration of the battery 50 (step S180), and when the high temperature state integration time Ttb is less than the high temperature allowable time Ttbref, the next processing is performed without specifying the high temperature factor. move on. Here, the high temperature permissible time Ttbref is determined in the embodiment whether or not the duration of the high temperature state of the battery 50 is long enough for the battery 50 to deteriorate with respect to vehicles of the same area and the same vehicle type as the vehicle 20. In order to do this, a time determined in advance by experiments or the like was used. In the embodiment, the “same area” as the vehicle 20 is a predetermined area to which the dealer of the vehicle 20 belongs (for example, Hokkaido, Tohoku, Kanto, Chubu, Kinki, China / Shikoku, Kyushu in Japan). , Regions classified as Okinawa). Considering the “same district” is based on the fact that the environment such as temperature may vary greatly depending on the district. The reason for considering the “same model” is that the capacity of the secondary battery, the rating of the motor, the presence or absence of the engine, and the like may differ depending on the model.

  Subsequently, whether or not the frequency (Cvhj / Tuse) obtained by dividing the number of high voltage states Cvhj of each battery cell of the battery 50 by the accumulated usage time Tuse of the battery 50 is equal to or higher than a predetermined high voltage allowable frequency Cvhref. When the frequency (Cvhj / Tuse) for the at least one battery cell is equal to or higher than the high voltage allowable frequency Cvhref, it is determined that the frequency at which the battery 50 is in a high voltage state is high (that is, a high voltage factor). It is specified as a factor that causes deterioration of the battery 50 (step S200). When the frequency (Cvhj / Tuse) is less than the high voltage allowable frequency Cvhref for all battery cells, the process proceeds to the next process without specifying the high voltage factor. . Here, in the embodiment, the high voltage allowable frequency Cvhref indicates whether the frequency of the high voltage state of the battery 50 is high enough for the battery 50 to deteriorate with respect to vehicles in the same area and the same vehicle type as the vehicle 20. In order to make a determination, a frequency determined in advance by an experiment or the like was used.

  Further, whether or not the frequency (Cvlj / Tuse) obtained by dividing the number of low voltage states Cvlj of each battery cell of the battery 50 by the accumulated usage time Tuse of the battery 50 is equal to or higher than a predetermined low voltage allowable frequency Cvlref. If the frequency (Cvlj / Tuse) for the at least one battery cell is equal to or higher than the low voltage allowable frequency Cvlref, it is determined that the battery 50 is frequently in a low voltage state (that is, a low voltage factor). 50 is specified as a factor that causes the deterioration (step S220), and when the frequency (Cvlj / Tuse) is less than the low voltage allowable frequency Cvlref for all battery cells, the process proceeds to the next process without specifying the low voltage factor. Here, in the embodiment, the low voltage allowable frequency Cvlref indicates whether or not the frequency of the low voltage state of the battery 50 is so high that the deterioration of the battery 50 proceeds with respect to a vehicle in the same area and the same vehicle type as the vehicle 20. In order to make a determination, a frequency determined in advance by an experiment or the like was used.

  Next, it is determined whether or not the full charge neglect frequency ratio (Ccn / Ccs) obtained by dividing the full charge neglect count Ccn of the battery 50 by the full charge count Ccs is equal to or greater than a predetermined full charge neglect ratio count threshold Ccref. When the determination is made (step S230), and the full charge neglected frequency ratio (Ccn / Ccs) is equal to or greater than the full charge neglected ratio frequency threshold Ccref, the duration of the state in which the battery 50 is close to full charge is long (that is, the full charge neglect factor) ) Is determined as a factor that causes the deterioration of the battery 50 (step S250), and this routine is terminated, and when the full charge neglect frequency ratio (Ccn / Ccs) is less than the full charge neglect frequency ratio threshold Ccref, Proceed to the next process without specifying the cause. Here, in the embodiment, the full charge neglected frequency ratio threshold value Ccref is set such that the battery 50 deteriorates for a longer time in a state in which the battery 50 is nearly fully charged with respect to a vehicle of the same area and vehicle type as the vehicle 20. In order to determine whether it is long or not, a ratio (for example, 50%, 60%, etc.) determined in advance by an experiment or the like is used.

  In addition, it is determined whether or not the full charge leaving time ratio (Tcn / Ton) obtained from the full charge leaving accumulated time Tcn of the battery 50 by the non-charging and discharging accumulated time Ton is greater than or equal to a predetermined full charge leaving time ratio threshold Tcref. When the determination is made (step S240) and the full charge leaving time ratio (Tcn / Ton) is equal to or greater than the full charge leaving time ratio threshold value Tcref, the battery 50 is in a state of being near full charge for a long time (that is, full charge). (Leaving factor) is specified as a factor that causes the deterioration of the battery 50 (step S250), and this routine is ended, and when the full charge leaving time ratio (Tcn / Ton) is less than the full charge leaving time ratio threshold value Tcref, it is left as it is. This routine ends. Here, the full charge leaving time ratio threshold value Tcref is set such that, in the embodiment, the deterioration of the battery 50 progresses in a state in which the battery 50 is in the same area and the same vehicle type as the duration time in which the battery 50 is almost fully charged. In order to determine whether it is long or not, a ratio (for example, 50%, 60%, etc.) determined in advance by an experiment or the like is used. By such factor identification processing, the high temperature factor, high voltage factor, low voltage factor, and full charge leaving factor of the battery 50 can be identified as factors that cause deterioration of the battery 50. The factor specifying process has been described above. Next, the factor determination process and the notification information setting process will be described.

  FIG. 5 is a flowchart illustrating an example of a factor determination notification information setting process routine executed by the server ECU 74 of the server 70. This routine is executed when the factor specifying process ends.

  When the factor determination notification information setting process routine of FIG. 5 is executed, the CPU 75 of the server ECU 74 firstly belongs to the area of the route on which the vehicle 20 actually traveled during the period during which the vehicle 20 actually traveled on this trip. For example, data such as the average temperature θout, average solar radiation amount Aout, average altitude Hdrv of the actual travel route, actual travel time Tdrv, and the like in the area that occupies the longest distance in the actual travel route are input and based on the input data. Then, the discrimination temperature θod, the discrimination solar radiation amount Aod, the discrimination altitude Hdd, and the actual running integrated time Tdd stored in the predetermined area of the HDD 72 are updated (step S300). As for the average temperature θout and the average solar radiation amount Aout, those stored as weather data in the weather DB 80 are input via communication via the network 19. The average altitude Hdrv of the actual travel route is input from the HVECU 60 via the network 19 by communication using the map data recorded by the navigation device 62 of the vehicle 20. The actual travel time Tdrv is input by communication via the network 19 as the time required for travel on this trip (time from system start-up to system stop for travel) by a timer (not shown) of the HVECU 60. It was supposed to be.

  Further, in the embodiment, when the temperature 20 for determination is newly registered in the HDD 72 so that the data of the vehicle 20 can be handled when the vehicle 20 is shipped, a value 0 is set as an initial value in a predetermined area of the HDD 72 ( The set discrimination temperature θod and the actual running accumulated time Tdd are stored, and the stored discrimination temperature θod and the actual running accumulated time Tdd, the average temperature θout and the actual running time input by the processing of step S300 are stored. Using Tdrv, the determination temperature Tod stored in the HDD 72 is updated with the value calculated by the following equation (1). The discrimination solar radiation amount Aod and the discrimination altitude Hdd are also stored in a predetermined area of the HDD 72 and updated by those calculated by the equations (2) and (3), similarly to the discrimination temperature θod. The actual travel integration time Tdd is updated by the sum of the stored actual travel integration time Tdd and the input actual travel time Tdrv after the calculation by the equations (1) to (3).

θod ← (θod ・ Tdd + θout ・ Tdrv) / (Tdd + Tdrv) (1)
Aod ← (Aod ・ Tdd + Aout ・ Tdrv) / (Tdd + Tdrv) (2)
Hdd ← (Hdd ・ Tdd + Hdrv ・ Tdrv) / (Tdd + Tdrv) (3)

  Subsequently, the weather information (sunny, cloudy, rain, snow, etc.) and the temperature of the district that mainly belongs to the actual travel route of the vehicle 20 during the period in which the vehicle 20 actually traveled on this trip, and the vehicle on the actual travel route The history data of 20 slips and grips and the battery voltage Vbj of each battery cell of the battery 50 are input at the above-mentioned predetermined sampling time data (ie, sampling data), and the value 0 is set as an initial value. The high and low voltage cumulative data number Cvhl, the slip cumulative data number Cvhls, and the slip cause ratio Rμ stored in the HDD 72 are updated by the following equations (4) to (6) and stored in a predetermined area of the HDD 72 (step S310). . Specifically, first, of the number of sampling data of the battery voltage Vbj, the number of high / low voltage data (high / low voltage data) classified as data that is equal to or higher than the charging side voltage threshold Vbref1 or the discharging side voltage threshold Vbref2 described above. Number) ΔCvhl is obtained. Next, by comparing the input sampling data with the same sampling timing, slips corresponding to the timing (period) in which there is a slip and grip history on the snowy road or ice board road among the divided high and low voltage data The data is classified and the number of slip data (the number of slip data) ΔCvhls is obtained. Next, the obtained high / low voltage data number ΔCvhl is added to the high / low voltage accumulated data number Cvhl stored in the HDD 72 to update the high / low voltage accumulated data number Cvhl by the equation (4), and the obtained slip time data number ΔCvhls. Is added to the cumulative data number Cvhls at the time of slip stored in the HDD 72, and the cumulative data number Cvhls at the time of slip is updated by Expression (5). Then, the slip-related ratio Rμ stored in the HDD 72 is replaced by the ratio of the cumulative data number Cvhls during slip to the updated high-low voltage cumulative data number Cvhl. Here, the weather information and temperature stored in the weather DB 80 as weather data are input via communication via the network 19. The slip and grip history data of the vehicle 20 is set to a value of 1 during the period in which the slip is determined by the HVECU 60 and the grip due to the slip is generated, and neither the slip nor the grip due to the slip is generated. For the period, a slip history flag Fs set to a value of 0 or the like can be used, and the period is input from the HVECU 60 via the network 19 by communication. In addition, the slip time data is classified into high / low voltage data in which the weather information after a predetermined time, such as several hours, is snow or the temperature is 0 ° C. or less and the history flag Fs is 1. And so on. In the embodiment, the slip-induced ratio Rμ is an average value of values calculated for each battery cell of the battery 50.

Cvhl ← Cvhl + ΔCvhl (4)
Cvhls ← Cvhls + ΔCvhls (5)
Rμ ← Cvhls / Cvhl (6)

  When the data is updated and stored in this manner, it is determined whether or not the high temperature factor of the battery 50 has been specified by the factor specifying process (step S320), and when it is determined that the high temperature factor has been specified, the updated and stored determination temperature θod. Is compared with a predetermined temperature threshold value θodref (step S330), and the updated and stored determination solar radiation amount Aod is compared with a predetermined solar radiation amount threshold value Aodref (step S340). Here, the air temperature threshold value θodref is for determining whether or not the duration time of the high temperature state of the battery 50 has become longer because the air temperature is high, and the solar radiation amount threshold value Aodref is because the solar radiation amount is large. This is for determining whether or not the duration time of the high temperature state of the battery 50 has become longer, and any of those determined in advance through experiments or the like can be used.

  When the discrimination temperature θod is less than the temperature threshold θodref and the discrimination solar radiation amount Aod is less than the solar radiation amount threshold Aodref, the user can improve the usage method of the vehicle 20 (including the driving method, the usage method of the equipment and the device), and the battery 50 It is determined that the high-temperature factor can be dealt with (step S350), and the high-temperature factor advice information determined in advance as advice for improving the usage method of the vehicle 20 is advice corresponding to the high-temperature factor of the battery 50. Is set as notification information to be notified to and stored in a predetermined area of the HDD 72 (step S360). On the other hand, when the determination temperature θod is equal to or higher than the temperature threshold value θodref or the determination solar radiation amount Aod is equal to or higher than the solar radiation amount threshold value Aodref, it is determined that the high-temperature factor of the battery 50 cannot be dealt with by the user's improvement in the usage method of the vehicle 20 (Step S370), notification information is not set.

  When it is determined in step S320 that the high temperature factor has not been specified, the process proceeds to the next process without executing the processes in steps S330 to S370.

  Subsequently, it is determined whether or not the low voltage factor of the battery 50 is specified by the factor specifying process (step S380). When it is determined that the low voltage factor is specified, it is determined in advance as the discriminating altitude Hdd that is updated and stored. The calculated altitude threshold value Hddref is compared (step S390), and the updated and stored slip cause ratio Rμ is compared with a predetermined slip cause ratio threshold value Rμref (step S400). Here, the altitude threshold Hddref is the frequency of the low voltage state of the battery 50 increased due to the fact that the output of the engine 22 tends to be small and the discharge power of the battery 50 tends to be large because the altitude is high and the atmospheric pressure is low. It is for determining whether or not, and a predetermined one can be used by experiments or the like. Further, the slip cause ratio threshold value Rμref determines whether or not the frequency of the low voltage state or the high voltage state of the battery 50 is increased due to the slip and grip of the vehicle 20 on a snowy road or an icy road. For this purpose, it is possible to use one previously determined by experiments or the like.

  When the determination altitude Hdd is less than the altitude threshold Hddref and the slip-caused ratio ratio Rμ is less than the slip-caused ratio threshold Rμref, it is determined that the high-voltage factor of the battery 50 can be dealt with by improving the usage method of the vehicle 20 by the user ( In step S410), advice corresponding to voltage factors (high voltage factor, low voltage factor) of the battery 50 and advice information for voltage factor predetermined as advice for improving the usage method of the vehicle 20 is notified to the user. The notification information to be set is set and stored in a predetermined area of the HDD 72 (step S420). On the other hand, when the determination altitude Hdd is equal to or higher than the altitude threshold Hddref or the slip-caused ratio Rμ is equal to or higher than the slip-caused ratio threshold Rμref, it is determined that the voltage factor of the battery 50 cannot be dealt with even by the user's improvement in the usage method of the vehicle 20. (Step S430), notification information is not set.

  When it is determined in step S380 that the low voltage factor is not specified, the process proceeds to the next process without executing the processes in steps S390 to S430.

  Further, it is determined whether or not the high voltage factor of the battery 50 has been specified by the factor specifying process (step S440). When it is determined that the high voltage factor has been specified, the updated and stored slip cause rate ratio Rμ The slip cause ratio threshold value Rμref is compared (step S450).

  When the slip cause ratio ratio Rμ is less than the slip cause ratio threshold value Rμref, it is determined that the high voltage factor of the battery 50 can be dealt with by improving the usage method of the vehicle 20 by the user (step S460). The information is set as notification information to be notified to the user and stored in a predetermined area of the HDD 72 (step S470). On the other hand, when the slip cause ratio Rμ is equal to or greater than the slip cause ratio threshold value Rμref, it is determined that the voltage factor of the battery 50 cannot be dealt with even by the improvement of the usage method of the vehicle 20 by the user (step S480), and the notification information is not set. .

  When it is determined in step S440 that the high voltage factor is not specified, the process proceeds to the next process without executing the processes in steps S450 to S480.

  Then, it is determined whether or not the full charge leaving factor of the battery 50 is specified by the factor specifying process (step S490), and when it is determined that the full charge leaving factor is specified, the full charge leaving factor of the battery 50 is dealt with. Fully charged neglect factor advice information as advice for improving the usage method of the vehicle 20 is set as notification information to be notified to the user and stored in a predetermined area of the HDD 72 (step S500). This routine is terminated. On the other hand, when it is determined that the full charge leaving factor is not specified, this routine is ended as it is. In the embodiment, a plurality of factors may be specified and a plurality of pieces of advice information may be set as notification information.

  FIG. 6 is an explanatory diagram illustrating an example of advice information corresponding to a factor specified as the deterioration of the battery 50 progresses. In the example of the figure, when the high temperature factor of the battery 50 is specified, if it is not determined that the high temperature factor has been specified due to high temperature or a large amount of solar radiation, the high temperature factor is improved by the improvement of the vehicle usage by the user. Therefore, predetermined high temperature factor advice information (for example, “use an air conditioner as much as possible”) corresponding to the high temperature factor is set as the notification information. On the other hand, when the high temperature factor of the battery 50 is specified, and it is determined that the high temperature factor is specified due to high temperature or a large amount of solar radiation, the high temperature factor is dealt with by improving the user's vehicle usage method. Since it is determined that it is not possible, the high temperature factor advice information is not set as the notification information. Further, when the low voltage factor of the battery 50 is specified, it is not determined that the low voltage factor has been specified due to the high altitude and the low atmospheric pressure, and slip and grip occur on snowy roads and icy roads. If it is not determined that the low voltage factor is identified due to the fact, it is determined that the low voltage factor can be dealt with by improving the user's vehicle usage. Therefore, a predetermined voltage factor corresponding to the voltage factor is determined. Advice information (for example, “Let's keep a gentle accelerator work”) is set as the notification information. On the other hand, when the low voltage factor of the battery 50 is specified, the low voltage factor is specified due to the high altitude and the low atmospheric pressure, or slip and grip occur on a snowy road or an ice board road. When it is determined that the low-voltage factor has been identified due to this, it is determined that the low-voltage factor cannot be dealt with by improving the user's vehicle usage method, so the voltage-factor advice information is not set as the notification information. Further, when the high voltage factor of the battery 50 is specified, if it is not determined that the high voltage factor has been specified due to the occurrence of slip and grip on a snowy road or an icy road, the voltage factor advice information is notified. Set as information. On the other hand, when the high voltage factor of the battery 50 is specified, when it is determined that the high voltage factor is specified due to the occurrence of slip and grip on a snowy road or an ice board road, Since it is determined that the high voltage factor cannot be dealt with by the improvement, the voltage factor advice information is not set as the notification information.

  By such factor identification processing (processing except steps S360, S420, S470, S490, and S500 in the routine of FIG. 5), predetermined discrimination data including weather data (in the embodiment, including temperature, solar radiation amount, and weather information) is included. Whether or not the factors previously identified by the factor identification process can be dealt with by improving the user's vehicle usage based on weather data, map data including altitude, and slip and grip history data of the vehicle 20) Can be determined. Further, when it is determined that the user can cope with the specific factor by improving the vehicle usage method, advice to the user is provided as notification information by notification information setting processing (steps S360, S420, and S470 in the routine of FIG. 5). Can be set. The factor specifying process and the notification information setting process have been described above. Next, the notification process will be described.

  FIG. 7 is a flowchart illustrating an example of a notification processing routine executed by the server ECU 74 of the server 70. This routine is executed when a signal requesting notification of advice is received from the user PC 16 or the portable terminal 18.

  When the notification process routine of FIG. 7 is executed, the CPU 75 of the server ECU 74 executes a process of reading the notification information set by the notification information setting process from a predetermined area of the HDD 72 (step S600), and the read notification information Is determined (step S610), and if it is determined that there is no notification information, the present routine is terminated as it is.

  On the other hand, when it is determined that the notification information is present, if there is a request from the user PC 16, a control signal is output so that the input notification information is displayed and output on the display 16a of the user PC 16 and also output from the speaker 16b. A control signal that is transmitted to the user PC 16 via the network 19 and, when requested by the portable terminal 18, the input notification information is displayed on the display 18 a of the portable terminal 18 and also output from the speaker 18 b. Is transmitted to the portable terminal 18 via the network 19 (step S620), and this routine is terminated. Receiving the control signal, the user PC 16 performs display output of the notification information on the display 16a and audio output from the speaker 16b. Moreover, the portable terminal 18 which received the control signal performs the display output of the alerting | reporting information to the display 18a, and the audio | voice output from the speaker 18b.

  By such processing, the user can know the advice for suppressing the deterioration of the battery 50, and can improve the driving method of the vehicle 20, the usage method of auxiliary equipment that consumes power, and the like. As a result, it is possible to suppress the life of the battery 50 from being shortened, and it is possible to suppress battery replacement that requires a great deal of cost. Further, even when a factor that causes deterioration of the battery 50 is specified, when it is determined that the factor is caused by the climate, the usage environment, etc. and the user cannot cope with this factor, Since advice predetermined as corresponding to the factor is not notified, the user can be prevented from feeling uncomfortable.

  According to the information notification system 10 of the embodiment described above, based on the monitoring data obtained by monitoring (monitoring) the state of the battery 50 mounted on the vehicle 20 together with the traveling motor MG2 and the like. A factor that causes deterioration of the battery 50 is specified, and it is determined whether or not the factor specified by improvement of the vehicle usage method of the user can be dealt with based on predetermined determination data including weather data. And when it is determined that the identified factor can be dealt with, information set in advance as advice for improving the user's vehicle usage method corresponding to the identified factor is set as information to be notified, When it is determined that the identified factor cannot be dealt with, the advice is not set as information to be notified. Thereby, the information advised in order to suppress deterioration of the battery 50 can be notified more appropriately.

  Moreover, when the duration (high temperature factor) of the predetermined high temperature state of the battery 50 is specified as a factor that causes deterioration of the battery 50 by the factor specifying process, it is obtained from the weather data for the period required for specifying. When it is determined that the discrimination temperature θod or the discrimination solar radiation amount Aod is not less than a predetermined temperature threshold value θodref or not less than the solar radiation amount threshold value Aodref, it is determined that the identified factor cannot be dealt with by improving the vehicle usage method of the user. Therefore, when the high temperature factor of the battery 50 due to traveling when the temperature is high or the amount of solar radiation is large is specified as the factor causing the deterioration of the battery 50, advice corresponding to the high temperature factor is not notified to the user. Can be.

  Further, when at least one of the frequency at which the battery 50 enters the low voltage state (low voltage factor) and the frequency at which the battery 50 enters the high voltage state (high voltage factor) is specified as a factor that causes the deterioration of the battery 50 by the factor specifying process. In addition, when it is determined that the slip cause ratio Rμ based on the weather data of the period required for identification and the slip and grip history data of the vehicle 20 is greater than or equal to a predetermined slip cause ratio threshold value Rμref, the user's vehicle Since it is determined that the specified factor cannot be dealt with by improving the usage method, the deterioration of the battery 50 is caused by the high voltage factor or the low voltage factor of the battery 50 due to slip and grip on a snowy road or an iced road. When it is specified as a factor to perform, it is possible not to notify the user of advice corresponding to these voltage factors.

  In addition, when the frequency that causes the battery 50 to be in a predetermined low voltage state (low voltage factor) is specified as a factor that causes deterioration of the battery 50 by the factor specifying process, the vehicle travels during the period required to be specified. When it is determined that the determination altitude Hdd obtained from the map data indicating the route is equal to or higher than a predetermined altitude threshold Hddref, it is determined that the specified factor cannot be dealt with by improving the user's vehicle usage. When the low voltage factor of the battery 50 due to traveling on a high route is identified as the factor that causes the deterioration of the battery 50, the advice corresponding to the low voltage factor may not be notified to the user.

  In the information notification system 10 of the embodiment, when the high temperature factor is specified as the factor causing the deterioration of the battery 50, the determination temperature θod is determined to be equal to or higher than the temperature threshold value θodref, or the determination solar radiation amount Aod is determined to be equal to or higher than the solar radiation amount threshold value Aodref. In this case, it is determined that the specified factor cannot be dealt with by improving the user's vehicle usage method, but only one of the determinations of the determination temperature θod and the determination solar radiation amount Aod is performed. Alternatively, both determinations may not be performed as long as determination processing for other factors is executed.

  In the information notification system 10 according to the embodiment, when the low voltage factor is specified as the factor causing the deterioration of the battery 50, the discrimination altitude Hdd is equal to or higher than the altitude threshold Hddref or the slip-causing rate threshold Rμ is predetermined. When it is determined that it is equal to or higher than Rμref, it is determined that the identified factor cannot be dealt with by improvement of the user's vehicle usage method, but one of the determinations of the determination altitude Hdd and the slip cause ratio Rμ Only the determination may be performed, or both determinations may not be performed as long as determination processing for other factors is executed.

  In the information notification system 10 of the embodiment, when it is determined that the slip cause ratio Rμ is greater than or equal to the predetermined slip cause ratio threshold Rμref when the high voltage factor is specified as the cause of the deterioration of the battery 50, Although it is determined that the identified factor cannot be dealt with by improving the vehicle usage method, the slip cause ratio Rμ may not be determined as long as the determination process for other factors is executed.

  In the information notification system 10 of the embodiment, when a low voltage factor or a high voltage factor is specified as a factor that causes deterioration of the battery 50, the specified factor cannot be dealt with by improving the vehicle usage method of the user. When determined, the predetermined advice corresponding to the voltage factor is not set as the notification information. However, even when it is determined that the specified factor cannot be dealt with, for example, the accelerator opening degree Acc When it is determined that the frequency of change (inclination) per unit time is greater than or equal to the threshold value compared to the data of the same district and the same vehicle type, a predetermined advice corresponding to the voltage factor is notified. Information may be set, i.e., in the example of FIG. 6, information such as “Let's keep a gentle accelerator work” may be notified.

  In the information notification system 10 of the embodiment, the frequency (Cvhj / Tuse) obtained by dividing the number of high voltage states Cvhj of each battery cell of the battery 50 by the accumulated usage time Tuse of the battery 50 is a predetermined high voltage allowable frequency Cvhref. By determining whether or not this is the case, the high voltage factor of the battery 50 is specified as the deterioration progress factor. Instead of or in addition to this, the charging power (Ib · Vb, but negative) of the battery 50 is determined. Is determined to be equal to or higher than a predetermined high charge power allowable frequency for the same area and the same vehicle model as the vehicle 20. Sometimes, the frequency of the high charge power state of the battery 50 (that is, the high charge power factor) may be specified as the deterioration progress factor. Moreover, it is good also as what performs the factor specific process using the charging / discharging current Ib of the battery 50, or the discharge current of each battery cell.

  In the information notification system 10 of the embodiment, the frequency (Cvlj / Tuse) obtained by dividing the number of low voltage states Cvlj of each battery cell of the battery 50 by the accumulated usage time Tuse of the battery 50 is a predetermined low voltage allowable frequency Cvlref.

The advice (specific factor advice information) predetermined as the advice is not set as information to be notified, that is, the advice is not notified, but information different from the specific factor advice information is set as information to be notified. It may be a thing. FIG. 8 is an explanatory diagram showing an example of advice information of this modification. In the figure, the part surrounded by a thick line frame is a part changed from “no advice” in FIG. 6 of the embodiment.

  In the example of FIG. 8, when it is determined that the high temperature factor is specified due to the high temperature or the amount of solar radiation when the high temperature factor of the battery 50 is specified, Since it is determined that the high temperature factor cannot be dealt with, information different from the high temperature factor advice information (for example, “When parking, let's park in the shade if possible”) is set as the notification information. Further, when the low voltage factor of the battery 50 is specified, the low voltage factor is specified due to the high altitude and the low atmospheric pressure, or slip and grip occur on a snowy road or an ice board road. When it is determined that the low-voltage factor has been identified, it is determined that the low-voltage factor cannot be dealt with by improving the user's usage of the vehicle, so information different from the voltage-factor advice information (for example, “elevation” Is high, the battery power consumption is likely to increase "and" slip / grip on snowy roads contributes to battery deterioration "). Further, when the high voltage factor of the battery 50 is specified, when it is determined that the high voltage factor has been specified due to the occurrence of slip and grip on a snowy road or icy road, Since it is determined that the high voltage factor cannot be dealt with by the improvement, information different from the voltage factor advice information (for example, “slip / grip on snowy roads contributes to battery deterioration”) is used as notification information. Is set.

  In the information notification system 10 of the embodiment, when the full charge neglect factor of the battery 50 is specified, full charge neglect factor advice information predetermined as advice corresponding to the full charge neglect factor (in the example of FIG. "Please make the battery fully charged as soon as possible before starting to use the vehicle as much as possible") is set as the notification information. However, the cause of leaving the battery 50 fully charged is identified and the vehicle starts running from a high altitude. When it is determined that the frequency of (trip start) is high, second full charge neglect factor advice information different from this full charge neglect factor advice information (for example, “start from a point with a high altitude is a downhill It is possible to regenerate the power because it can be expected. It is not necessary to fully charge. In this case, the second full charge neglect factor advice information corresponds to a calculated value of what percentage of power regeneration can be expected and a full charge as a charge plan for charging the battery 50 with the external power source 58. It is also possible to include an option as to whether or not to select a plan for charging up to a rate SOCa obtained by subtracting a calculated value that can be expected to regenerate power from the rate SOCf. In this case, when the user selects this charging plan, information to that effect is transmitted to the vehicle 20, and the vehicle 20 may end the charging of the battery 50 by the external power source 58 at the rate SOCa. On the other hand, the second full charge neglect factor advice information includes only the calculated value of what percentage of power regeneration can be expected, and it is determined by the external power source 58 of the battery 50 at the ratio SOCa without allowing the user to select it. Charging may be automatically terminated.

  In the information notification system 10 of the embodiment, the setting and presentation of the charging plan as described above is not particularly described, but the low cost is considered in consideration of the electricity bill provided by the power company and the user's vehicle usage time. The charging plan may be set or presented so as to realize charging by the external power source 58 of the battery 50 in FIG. For example, if the electric power company prepares a first type contract that reduces the electricity bill at night compared to the daytime and a second type contract that does not change the electricity bill at night and daytime, Charging plans such as "Your electricity bill plan is the second type of contract, so if you follow it, the optimal charging plan will be as follows. Do you want to select this charging plan?" It is good also as what presents. In this case, when the charging plan selected by the user is selected, information to that effect is transmitted to the vehicle 20, and the vehicle 54 charges the battery 50 with the electric power from the external power source 58 according to the charging plan. Can be controlled. In this way, since the user can know his / her electricity bill plan, he / she misunderstands that he / she has the first type contract even though he / she originally has the second type contract. Inconvenience can be suppressed.

  In the embodiment, the battery 50 of the vehicle 20 is a lithium ion secondary battery, but may be any type of secondary battery such as a nickel hydride secondary battery, a nickel cadmium secondary battery, or a lead storage battery. Absent.

  In the embodiment, a hybrid vehicle of a type including an engine 22, two motors MG1, MG2, and a battery 50 connected to the motors MG1, MG2 is used as an example of the vehicle 20 and applied to the information notification system 10 of the present invention. As described above, any type of hybrid vehicle or electric vehicle can be applied to the information notification system of the present invention as long as the vehicle includes a traveling motor and a secondary battery electrically connected to the motor.
