Description

  The present invention relates to a battery status display device such as an engine start battery for a vehicle.

  2. Description of the Related Art Conventionally, a battery status display device that detects and displays a remaining life and a deteriorated status in the field of a lead battery for starting an engine of a vehicle has been proposed, and some of them have been put into practical use. Such a battery status display device is connected between battery terminals, calculates the remaining life and deterioration status of the battery based on the battery voltage and impedance, and displays the result on a display device such as a light emitting diode or a liquid crystal panel. .

  As a result display method in the vehicle battery status display device, for example, in Patent Document 1, an abnormal battery status and a coping method are displayed with characters and light emitting diodes, and four status indicators are arranged in a line on the status display section. It is shown that each display of “battery OK (green)”, “hosseiyo (red)”, “Jumyokides”, and “juden, Moshikuwa Battery Tenkenseyo (red)” is performed with a diode.

  In general, as a factor of battery performance deterioration, it is unavoidable that the battery or active material is deteriorated due to the passage of time of use, that is, due to deterioration of the battery itself, misuse or abnormal use by the user or Due to the poor matching with the device (vehicle), the battery can be temporarily or permanently deteriorated, that is, the deterioration having the factor other than the battery.

  For example, the degree of deterioration of engine startability due to the lapse of years of battery use is mostly determined by the degree of deterioration of the positive electrode plate, the negative electrode plate, or other battery components inside the battery, and can be classified as deterioration of the battery itself.

  On the other hand, if the vehicle is left with the interior light of the vehicle, such as a half-door, left on, the battery is discharged by the interior light, and the engine cannot be started. Even if the interior light is not emitted, if the vehicle is left for a long period of time such as several months, the battery is discharged due to the dark current to the vehicle, and the engine cannot be started. Further, the alternator on the vehicle side may break down and the battery cannot be charged, or on the contrary, it may be overcharged and the engine cannot be started. The deterioration phenomenon of these batteries is not in the battery itself, but is caused by misuse or abnormal use by the user or on the vehicle side as equipment.

  In this way, battery performance degradation is mainly divided into factors that are caused by the battery itself, and factors other than the battery, that is, factors that are caused mainly by the usage pattern and the vehicle side. The method is also different.

  Taking the status display of Patent Document 1 as an example, “Battery OK” and “Jumyokeides” indicate the degree of deterioration of the battery itself. If the light emitting diode of “Jumyokeides” emits light, replace the battery. Is the only solution.

  On the other hand, in the case of “Juden, Moshikuwa Battery Tenkensei (red)”, the battery deterioration factors include those caused by the battery usage mode or the vehicle side. For example, in the case of battery deterioration due to misuse such as forgetting to turn off the light, the battery is simply in a discharged state, battery replacement is unnecessary, and supplementary charging may be effective as a countermeasure.

  In addition, due to vehicle-side factors such as failure of the vehicle charging system including the alternator, the deterioration of the battery after replacement only occurs when the battery is replaced. Therefore, vehicle inspection and repair are required in addition to battery replacement. .

  As described above, a countermeasure for battery performance deterioration differs depending on whether the deterioration is attributable to the battery itself or whether there is a factor on the user side or the vehicle side.

  Accordingly, the display of the battery state detection result is required to have display characteristics such as easy viewing and easy recognition so that the user can appropriately respond.

In view of such display characteristics, in the configuration of Patent Document 1, the deterioration factor is caused by the battery and the others are mixed in the display row of the light emitting diodes, and the user can display these indications. There was a difficulty in recognizing how to deal with it.

(First embodiment)
The configuration of the battery status display device according to the first embodiment of the present invention will be described.

  FIG. 1 relates to claim 1 of the present invention, and shows a state display area 103 of a battery state display 101 according to the first embodiment of the present invention. The battery status display device 101 is provided integrally with the battery 102 as shown in FIG. 3, or is provided separately from the battery 102 as shown in FIG. 4, and the battery 102 and the battery status display device 101 are connected to each other. They can be connected by a line 105. The same applies to the battery status display device 106 according to the second embodiment described later.

  The battery status display device 101 according to the present invention is a light emitting device (A1 in the example of FIG. 3) in which status detection results output from a status detector (not shown) that detects the status of the battery 102 are arranged in the status display area 103. ~ An, B1, B2).

  The battery state apparatus 101 of the present invention is characterized by the arrangement of the light emitting devices arranged in the state display area 103 and the light emission order of the light emitting devices, and is necessary for detecting the battery state. It goes without saying that means for measuring detection parameters such as voltage, battery temperature, battery internal resistance, etc., or means for calculating the battery state using these parameters are provided. Known means can be applied.

  The battery state device 101 of the present invention is assumed to proceed according to the frequency of use of the battery 102, not the degree of deterioration having a factor in the battery 102 itself, that is, the deterioration based on the abnormality on the device side or the misuse on the user side. A plurality of n first light emitting devices (A1 to An) that display in stages the degree of deterioration of the power generation element of the battery 102 (hereinafter referred to as the first degree of deterioration) such as an active material or separator. Is arranged.

  For example, as a method for determining the first degree of deterioration, a relationship between the battery internal resistance (IR) for each state of charge (SOC) and the remaining life period or engine startability is obtained in advance, and the SOC and IR measurements are performed. The remaining life period and engine startability can be obtained. In addition, in a lead battery, since SOC shows a strong correlation with the open circuit voltage (OCV) of a battery, it can be estimated from OCV. IR can be directly measured by a so-called impedance meter.

  Since the first deterioration degree proceeds according to the usage frequency of the battery, a plurality of light-emitting devices (hereinafter referred to as first light-emitting devices) A1 to An (n) are displayed in correspondence with this. ≧ 2) are arranged in a row in the state display area 103. Here, n needs to be displayed at least in two stages, at least good and need to be replaced, so that n ≧ 2, and in order to accurately notify the user of the degree of deterioration, subdividing, in particular, n ≧ 3 or more is preferable.

  The first light emitting devices A1 to An are arranged close to one side 103a of the state display area 103 and close to the side 103a. In addition, notations 107 such as “replacement”, “starting caution”, and “good” are displayed as necessary.

  Further, according to the present invention, in addition to the first deterioration degree which is the deterioration degree of the battery itself, the degree of battery deterioration due to the user's misuse or abnormal use or malfunction on the equipment side such as a vehicle (not a battery factor) ( A second display device indicating the second degree of deterioration is provided in the state display area 103. Note that the number of second display devices is, for example, one each corresponding to a misuse / abnormal use on the user side and one corresponding to a device side malfunction (light emitting devices B1, B2 in FIG. 1). Corresponding to the above). Of course, if necessary, one of them is omitted to make one total, or one of the displays is made to be a stepped display, and as a result, the number of second light emitting devices becomes three or more in total. Also good.

  In order to deal with misuse and abnormal use on the part of the user, there are forgetting to turn off the lights and leaving the vehicle for a long time. In such a usage pattern, the battery OCV gradually decreases. Therefore, when the battery voltage is measured at regular intervals and the battery voltage decreases monotonously, such a usage pattern is supplemented to the user. In order to notify the charging, for example, a notation “requires charging” may be attached to one of the light emitting device B1 and the light emitting device B2, and this may be emitted.

  As a countermeasure for the failure on the vehicle side, there is a failure in the battery charging system. The failure of the battery charging system can be detected relatively easily by the charging voltage. Normally, in a 12V lead battery, the charging voltage is set to about 14.0-14.5V. However, if the charging voltage range deviates greatly and continuously, a failure of the battery charging system (example of FIG. 3) In this case, the light-emitting device B2 or B1 can emit light.

  In the present invention, it is substantially parallel to the side 103a adjacent to the first light-emitting devices A1 to An arranged in a row, and on the vehicle side or the user side to which the battery is connected in the vicinity of both ends or one end of the opposite side 103b. The second light emitting devices B1 and B2 that display the second battery deterioration level having a factor are arranged. As shown in FIG. 1, when two second light emitting devices are arranged, they are arranged near both ends of the side 103b, and when one second light emitting device is arranged, they are arranged near one end of the side 103b.

  As described above, the first light emitting device (A1 to An) that displays the first battery deterioration degree and the second light emitting device (B1, B2) that display the second deterioration degree that have different factors and countermeasures. By arranging the arrays so as to be separated from each other, the user can easily recognize the countermeasure without error.

Further, in this configuration, the light emitting device (B1) corresponding to the deterioration having the factor on the equipment side and the light emitting device (B2) corresponding to the deterioration having the factor on the user side are provided, but the equipment side and the user side are provided. The same effect can be obtained even if the second battery deterioration degree having a factor is displayed by one light emitting device. Further, as one of the light emitting device in this case, a plurality of light emitting devices emitting colors different from each other Ru using those together. In this case, the battery deterioration due to misuse, for example, the battery deterioration due to continuous discharge is yellow, and the deterioration due to abnormality in the charging system is red, and can be displayed by a single light emitting device.

(Second Embodiment)
The battery state display device 106 according to the second embodiment of the present invention is provided with the state display region 104 shown in FIG. 2 instead of the state display region 103 in the battery state display device 101 according to the first embodiment. is there. In the state display area 104, first light emitting devices A1 to An and second light emitting devices (B1 and B2 in the example of FIG. 2) having the same configuration as that described in the first embodiment are arranged. Is done.

  The first light emitting devices (A1 to An) are arranged in a row in parallel and close to one diagonal line x of the state display region 104. As in the first embodiment, the first light emitting devices A1 to An are for indicating the degree of deterioration of the battery itself, and need to be two or more, and the user subdivides and determines the degree of battery deterioration. Therefore, 3 or more are preferable.

  Furthermore, in the second embodiment, the second light emitting device (B1, B2) that displays the second battery deterioration level having a factor on the vehicle side or the user side to which the battery is connected is replaced with the first light emitting device A1. Are arranged in the vicinity of the apex of the state display area 104 corresponding to the other diagonal line y intersecting with the diagonal line x close to the column of An.

  In this way, the first light emitting devices A1 to An that display the first battery deterioration degree and the second light emitting devices B1 and B2 that display the second battery deterioration degree are separated from each other. Thus, the user can easily recognize the countermeasure without error.

  Also in the second embodiment, as in the first embodiment, the light emitting device (for example, the light emitting device B1) that displays the degree of deterioration having a factor on the vehicle side and the deterioration having a factor on the user side are supported. Although the light emitting device (for example, the light emitting device B2) is provided, the second battery deterioration degree having a factor on the device side and the user side is displayed with one light emitting device, and the status display corresponding to one end of the diagonal line y The same effect can be obtained even if the area 104 is arranged near the vertex.

  In any of the first and second embodiments, a description 107 of characters, symbols, figures, or the like appropriately expressing the meanings of the first light emitting devices A1 to An and the second light emitting devices B1 and B2 is used. Can be arranged.

(Third embodiment)
A third embodiment of the present invention corresponding to the third aspect of the present invention will be described.

  In the third embodiment, the light emission order of the first light emitting devices A1 to An in the state display areas 103 and 104 described in the first and second embodiments is defined.

  It is assumed that the first light emitting device Ak (where 1 ≦ k ≦ An) corresponds to the first deterioration state of the battery in a state. In the present invention, prior to the light emission of the first light emitting device Ak, the first light emitting device Am (1 ≦ Am ≦ k−1) is sequentially emitted in ascending order of m.

  Hereinafter, as an example, a light emission method in the case where the number n of the first light emitting devices is 5 and the light emitting device corresponding to the level at which the deterioration degree should be displayed is A4 (k = 4) will be described.

  As shown in FIG. 5, the first light emitting devices A1, A2, A3, and A4 are caused to emit light sequentially with the passage of time, the first light emitting device A4 emits light, and after a certain time has elapsed, the first light emitting device A1. All of .about.A4 are turned off for a predetermined time, and the first light emitting devices A1 to A4 are again sequentially emitted in ascending order. With this light emission pattern, the visibility of display can be remarkably improved as compared with the case where the corresponding first light emitting device A4 emits light alone. In particular, the visibility is further enhanced by repeating this emission pattern.

  Further, instead of the light emission pattern of FIG. 5, a light emission pattern as shown in FIG. 6 may be used. In the light emission pattern of FIG. 6, the first light emitting devices A1 to A4 emit light in ascending order, but the first light emitting devices A1 to A3 are turned off once after light emission, and the first light emitting devices A1 to A3 correspond to the levels to be displayed. The first light emitting devices A1 to Am (A1 to A3 in the example of FIG. 6) emit light simultaneously with the light emission of one light emitting device Ak (k = 4 in the example of FIG. 6), and then turn off all at once after a predetermined time. It is a pattern to do. It should be noted that the visibility is more remarkably enhanced by repeatedly performing this light emission pattern.

(Fourth embodiment)
A fourth embodiment of the present invention corresponding to the fourth aspect of the present invention will be described.

  In the fourth embodiment, the light emission order of the first light emitting devices A1 to An in the state display areas 103 and 104 described in the first and second embodiments is defined.

  In the fourth embodiment, the number n of the first light emitting devices is 3 or more. First light-emitting device Ai (2 ≦ i ≦ n) serving as a reference from among the first light-emitting devices (A2 to An-1) excluding the first light-emitting devices (A1, An) arranged at both ends of the row -1) as a reference.

  When k in the light emitting device Ak (1 ≦ k ≦ n) corresponding to the level to be displayed of the first deterioration degree is 1 ≦ k <i, the first light emitting devices (Ak to Ai) are arranged in descending order. Lights sequentially.

  Further, when k in the light emitting device Ak (1 ≦ k ≦ n) corresponding to the level to be displayed of the first deterioration degree is i <k ≦ n, the first light emitting devices (Ai to Ak) are arranged in ascending order. When light is emitted sequentially and k in the light emitting device Ak (1 ≦ k ≦ n) corresponding to the level to be displayed of the first deterioration degree is equal to i, only the first light emitting device (Ai) is caused to emit light.

  For example, when the number n of the first light emitting devices is 5, and the reference first light emitting device Ai is the light emitting device A3 (i = 3), the first degradation degree corresponds to the level to be displayed. When the light emitting device is A1 (k = 1), k is 1 ≦ k <i, so light is emitted at time intervals in the order of light emitting devices A3, A2, and A1 (descending order). All of the light emitting devices A1 to A3 are turned off for a certain period of time, and the light emitting devices A3 to A1 are sequentially made to emit light in descending order again. This light emission pattern may be repeated.

  Next, when the light emitting device corresponding to the level to be displayed of the first deterioration degree is A5 (k = 5), k is i <k ≦ n, and therefore the order of the light emitting devices A3, A4, A5 (ascending order). The light is emitted at a certain time interval, and after a certain time elapses, all of the light emitting devices A3 to A5 are turned off for a certain time, and the light emitting devices A3 to A5 are again sequentially emitted in ascending order. This light emission pattern may be repeated.

  Next, when the light emitting device corresponding to the level to be displayed of the first degree of deterioration is A3 (k = 3), since k = i, only the light emitting device A3 always emits light or blinks at a predetermined time interval.

  As an example, when the first light emitting device A1 side is in a state in which the first deterioration is the most advanced, and the first light emitting device An (A5 in this embodiment) is in the state in which the first deterioration is the smallest. By setting the reference light emitting device (Ai), when 1 ≦ k <i and the light emitting device emits light in descending order of Am, it is easily recognized that the deterioration degree of the battery itself is relatively advanced. it can.

  Further, when the light emitting device emits light in ascending order of Am with i <k ≦ n, it can be easily recognized that the deterioration degree of the battery itself is not relatively advanced and is in a good state. When the light emitting device Ai blinks with = i, it can be easily recognized that the deterioration degree of the battery itself is at an approximately intermediate level. That is, since the degree of deterioration can be recognized according to the movement direction of light emission, the visibility is extremely high.

  Also in the fourth embodiment, the light emission pattern as shown in FIGS. 5 and 6, that is, the first light emitting device is caused to emit light repeatedly, and after the predetermined first light emitting device emits light, the whole The light emission pattern for turning off the light (FIG. 5), the repetition of this light emission pattern, and further, the first light emitting device is made to emit light alone in sequence, and the light emission is performed together with the first light emitting device that previously emitted light according to the light emission of the predetermined light emitting device. Thus, a light emission pattern (FIG. 6) that turns off all at once and this light emission pattern can be repeated.

  In the first to fourth embodiments, the first light emitting device A1 side may be in a state where the battery is most favorable, and the first light emitting device An side may be in a state where battery deterioration is most advanced and needs replacement, The reverse setting, that is, the first light emitting device An side may be in a state where the battery is most favorable, and the first light emitting device A1 side may be in a state where battery deterioration is most advanced and needs replacement.

  In each of the light emitting devices in the first to fourth embodiments, as a matter of course, a plurality of display colors such as red, yellow, green, and blue can be used to increase the visibility of the result display.

  The shape of the state display areas 103 and 104 is also a rectangle, and a square or a rectangle is the most basic, but can be modified to a parallelogram, a rhombus, or a trapezoid. In addition, it is also within the range where the effect of the present invention can be obtained without impairing the visibility of the light emitting device, by making the apex of these quadrangles R shape or making the side a gentle curve (for example, barrel shape). Modifications can also be made.

  As described above, according to the configuration of the present invention, the visibility of the result display of the battery state display device can be remarkably improved. In particular, when the battery has failed, even if the subsequent action differs depending on the deterioration factor of the battery, such as battery replacement, supplementary charging, or inspection of the equipment such as the vehicle, it is clear that the user will not make a mistake. Display is possible.

  The present invention can easily recognize the performance degradation due to the battery itself with different handling methods and the performance degradation of the battery due to factors on the user side and the device side, and has excellent visibility. Very suitable.
