- the storage amount display unit 53 represents the amount of electricity stored in the capacitor 64 according to the number of bar-shaped elements that are lit.
- Table 1 below shows an example of the amount of electricity corresponding to the number of bar-shaped elements that are lit.
- ⁇ V (1) is larger than ⁇ V (2)... ⁇ V (7). That is, the difference between the maximum charged amount and the minimum charged amount of the capacitor 64 in a state where the number of bar-shaped elements to be lit is one indicates that the capacitor 64 in a state where the number of bar-shaped elements to be lit is any number of two or more It is larger than the difference between the maximum storage amount and the minimum storage amount.
- the voltages from V (2) to V (7) are voltages at which the capacitor 64 is normally used, and ⁇ V (2)... ⁇ V (7) is set to a small value.

- the power output from the capacitor 64 to the inverters I1, I2, I3 is positive, and the power output from the inverters I1, I2, I3 to the capacitor 64 is negative. That is, when the power is negative, it means that the capacitor 64 is charging, and when the power is positive, it means that the capacitor 64 is discharged.
- the state determination unit 51 acquires the power passing through the booster BT every predetermined sampling time, and calculates the average value per predetermined time ⁇ t1 as the average passing power.
- step S11 the state determination unit 51 determines whether or not the state display unit 52 has displayed “charging state” immediately before.
- the state determining unit 51 determines whether or not the average passing power is less than the first threshold (step S12).
- step S13 the state determining unit 51 determines whether or not the average passing power is less than the second threshold (step S13).
- the second threshold is smaller than the first threshold, and both the first threshold and the second threshold are negative values. That is, the absolute value of the second threshold is larger than the absolute value of the first threshold.
- the first threshold value and the second threshold value are predetermined values and are stored by the control unit 31.
- the charge flag is set to True (step S14 or step S15).
- the charge flag is set to False (step S20).
- the charge flag is a Boolean flag used by the state determination unit 51 to determine the “charge state” or the “discharge state” and has a value of either True or False.
- step S16 the state determination unit 51 determines whether the first counter value is less than the minimum display count.
- the first counter is a counter for measuring the time when the “charge state” is displayed on the state display unit 52. By multiplying this counter value by the time interval ⁇ ts for executing step S1, it is possible to calculate the time during which the “charge state” is displayed.
- the minimum number of display times is a predetermined value stored by the control unit 31, and is a counter value representing a minimum time ⁇ t2 for continuously displaying “charge state”. Therefore, when the first counter value is less than the minimum display count (Yes in step S16), it means that the minimum time for continuously displaying the “charge state” has not been reached.
- step S19 the state determination unit 51 determines the state to be displayed on the state display unit 52 as “charge state”, and causes the state display unit 52 to display “charge state”.
- the first counter value is equal to or greater than the minimum display number (No in step S16)
- state determination unit 51 determines the state displayed on state display unit 52 as “charged state” without changing the first counter value. Then, the “charge state” is displayed on the state display unit 52 (step S19).
- step S18 the state determination unit 51 resets the first counter. That is, the state determination unit 51 sets 0 to the counter value of the first counter. Thereafter, the state determination unit 51 determines the state to be displayed on the state display unit 52 as “charge state” and causes the state display unit 52 to display “charge state” (step S19). After step S19 ends, the process returns to step S1.
- step S21 the state determination unit 51 determines whether or not the discharge flag is true.
- the discharge flag is a Boolean flag used by the state determination unit 51 to determine “charge state” or “discharge state”, and has a value of either True or False. A method for setting the value of the discharge flag will be described later.
- the state determination unit 51 sets the minimum display count as the counter value of the first counter (step S22). That is, the “charging state” is not displayed on the state display unit 52 in steps S23 to S25 described later.
- Step S23 the state determination unit 51 determines whether or not the first counter value is less than the minimum display count.
- the first counter value is less than the minimum display count (Yes in step S23)
- 1 is added to the first counter in step S24. In other words, the first counter is incremented.
- the state determination unit 51 determines the state to be displayed on the state display unit 52 as “charge state”, and causes the state display unit 52 to display “charge state” (step S25).

- the process returns to step S1.
- FIG. 9A and FIG. 9B are flowcharts showing the flow of processing in which the state determination unit 51 determines the discharge state. Also in this case, first, in step S1, the state determination unit 51 calculates the average passing power. Next, in step S31, the state determination unit 51 determines whether or not the state display unit 52 has displayed “discharge state” immediately before. When “discharge state” is displayed immediately before (Yes in step S31), the state determination unit 51 determines whether or not the average passing power is larger than the third threshold (step S32). When the “discharge state” is not displayed immediately before (No in Step S31), the state determination unit 51 determines whether or not the average passing power is larger than the fourth threshold (Step S33).
- the fourth threshold is larger than the third threshold, and both the third threshold and the fourth threshold are positive values. That is, the absolute value of the fourth threshold is greater than the absolute value of the third threshold.
- the third threshold value and the fourth threshold value are predetermined values and are stored by the control unit 31.
- the discharge flag is set to True (step S34 or step S35).
- the discharge flag is set to False (step S40).
- step S36 the state determination unit 51 determines whether the second counter value is less than the minimum display count.
- the second counter is a counter for measuring the time when the “discharge state” is displayed on the state display unit 52. If this counter value is multiplied by the time interval ⁇ ts for executing step S1, the time during which the “discharge state” is displayed can be calculated.
- the minimum number of display times is a predetermined value stored by the control unit 31, and is a counter value representing a minimum time ⁇ t2 for continuously displaying the “discharge state”. Therefore, when the second counter value is less than the minimum display number (Yes in step S36), it means that the minimum time for continuously displaying the “discharge state” has not been reached.
- step S39 the state determination unit 51 determines the state displayed on the state display unit 52 as the “discharge state” and causes the state display unit 52 to display “discharge state”.
- the state determination unit 51 determines that the state displayed on the state display unit 52 is “discharge state” without changing the second counter value. Then, the “discharge state” is displayed on the state display unit 52 (step S39).
- step S38 the state determination unit 51 resets the second counter. That is, the state determination unit 51 sets 0 to the counter value of the second counter. Thereafter, the state determination unit 51 determines the state to be displayed on the state display unit 52 as “discharge state”, and causes the state display unit 52 to display “discharge state” (step S39). After step S39 ends, the process returns to step S1.
- step S41 the state determination unit 51 determines whether or not the charge flag is true.
- the state determination unit 51 sets the minimum display count as the counter value of the second counter (Step S42). That is, the “discharge state” is not displayed on the state display unit 52 in steps S43 to S45 described later.
- the state determination unit 51 determines whether the second counter value is less than the minimum display count.
- the second counter value is less than the minimum display count (Yes in step S43)
- 1 is added to the second counter in step S44. In other words, the second counter is incremented.
- the state determination unit 51 determines the state displayed on the state display unit 52 as “discharge state” and causes the state display unit 52 to display “discharge state” (step S45). According to steps S43 to S45, although the discharge flag is false, the charge flag is not true and the predetermined time ⁇ t2 has elapsed since the state displayed on the state display unit 52 changes to the discharge state. Until then, the state determination unit 51 determines the state of display of the discharge state (that is, the state after the change) on the state display unit 52. When the second counter value is equal to or greater than the minimum display count (No in step S43), or when step S45 ends, the process returns to step S1.
- steps S43 to S45 are executed only when both the discharge flag and the charge flag are false. If one of the charge flag and the discharge flag is true, step S19 or S39 is always executed, so the state determination unit 51 uses the first to fourth threshold values to display the state displayed on the state display unit 52. Either the charged state or the discharged state can be determined. Therefore, steps S43 to S45 are executed when the state determination unit 51 sets the state displayed on the state display unit 52 using the first to fourth thresholds to the charged state or the discharged state. Only when it cannot be determined. Similarly, steps S23 to S25 are executed only when both the discharge flag and the charge flag are False. Therefore, the steps S23 to S25 are executed when the state determination unit 51 sets the state displayed on the state display unit 52 using the first to fourth thresholds to the charged state or the discharged state. Only when it cannot be determined.
- step S21 may be executed after any of steps S34, S35, and S40 is completed.
- step S41 may be executed after any of steps S14, S15, and S20 is completed.
- the process for determining whether or not the battery is “discharged” and the process for determining whether or not the battery is “charged” may be sequentially performed.
- the processing of steps S1 to S15 and step S20 and the processing of steps S1 to S35 and step S40 are executed first, the processing of steps S16 to S19, S21 to S25, and steps S36 to S39. , S41 to S45 may be executed later.

- time t6 to t8 the work vehicle 1 moves backward.
- work vehicle 1 moves forward.
- time t7 to t9 the work vehicle 1 performs a so-called shuttle operation to switch to the forward clutch CF while moving backward.
- FIG. 10 (b) shows a time-series change in the power passing through the booster BT when the work vehicle 1 performs the work of FIG. 10 (a).
- the power when the power is positive, it indicates that the capacitor 64 is discharged. And when electric power is negative, it has shown that the capacitor 64 is charging.
- the work vehicle 1 uses the output of the engine 21 for the operation of the work machine 3, unlike a general automobile. Therefore, the fluctuation of electric power due to charging / discharging of the capacitor 64 is more severe than that of a general automobile. For this reason, there is a state in which the fluctuation of the power changes in a spike shape.
- FIG. 10 (c) shows an example in which charge display / discharge display is performed based on the power fluctuation of FIG. 10 (b).
- a discharge display is displayed, and when power is a negative value, a charge display is displayed. If the charge display / discharge display as shown in FIG. 10 (c) is displayed to the operator, it is difficult for the operator to visually recognize because the short-time discharge / charge is switched.

- FIG. 11 (a) shows the same change in vehicle speed as in FIG. 10 (a).
- FIG. 11 (d) shows an average value (average passing power) per predetermined time ⁇ t1 with respect to the voltage of FIG. 10 (b). In this case, ⁇ t1 is 0.5 seconds.
- FIG. 11 (e) shows an example in which the charge display / discharge display is performed based on the fluctuation of the average passing power in FIG. 11 (d).
- the average passing power is a positive value in FIG. 11 (d)
- the display is discharging, and when the average passing power is a negative value, the charging display is used.
- the average passing power is close to 0 between times t1 and t4, and positive and negative changes frequently occur. For this reason, it is difficult for the operator to visually recognize, particularly when the short-time discharge / charge is switched between the times t1 and t4.
- FIG. 11 (f) shows the result of adding the processing of steps S12, S13, S32, and S33.

- the charge display / discharge display is performed at a minimum for the time ⁇ t2. Specifically, the time ⁇ t2 is 1 second.
- the charge display / discharge display is prevented from being visually recognized by the operator because the charge display / discharge display is extremely short.

However, in the charged amount display unit 53, the difference between the maximum charged amount and the minimum charged amount of the capacitor 64 in a state where the number of bar-shaped elements to be lit is one indicates that there are two or more bar-shaped elements to be lit The difference between the maximum charged amount and the minimum charged amount of the capacitor 64 in the state of Therefore, the above-described deterioration in workability is prevented. Further, at the voltage at which the capacitor 64 is normally used, the difference between the maximum charged amount and the minimum charged amount is reduced, and a bar-shaped element corresponding to the charged amount is provided. Therefore, the operator can easily determine whether the amount of power stored in the capacitor 64 is larger or smaller than the normal charged amount.

Therefore, since the display positions of the charge state / discharge state are different, the visibility by the operator is improved. As shown in FIG. 5 and the like, when the first display element 55 and the second display element 56 are arranged at positions that are symmetrical with respect to the storage amount display unit 53, the operator changes between the charged state and the discharged state. Can be more easily identified. Further, the color displayed by the first display element 55 and the color displayed by the second display element 56 are different. For this reason, it becomes easier for the operator to distinguish between the charged state and the discharged state.
- the state display unit 52 displays an arrow head toward the storage amount display unit 53.

Therefore, it becomes easier for the operator to distinguish between the charged state and the discharged state.
- the state display unit 52 lights up from the first display element 55 toward the element 55a closest to the storage amount display unit from the element 55c farthest from the storage amount display unit 53. It displays so that an element may move in order. This makes it easier for the operator to understand that power is being output toward the capacitor 64 when the capacitor 64 is in a charged state. Therefore, it becomes easier for the operator to identify the state of charge.

This makes it easier for the operator to understand that power is being output from the capacitor 64 when the capacitor 64 is in a charged state. Therefore, it becomes easier for the operator to identify the discharge state.
- the average passing power is used in which the power output from the capacitor 64 to the inverters I1, I2, I3 is positive and the power output from the inverters I1, I2, I3 to the capacitor 64 is negative.
