Detailed Description
[ Embodiment 1]
[ Integral Structure ]
Fig. 1 is a diagram showing an electric vehicle according to embodiment 1 of the present invention. The electric vehicle 1 is a vehicle that travels using electric power from a battery (secondary battery) 2. The electric vehicle 1 is connected to a charging device 3 by a cable, charges a battery 2 by electric power supplied from the charging device 3, and travels by electric power of the battery 2. In addition, at the time of deceleration, the battery 2 is charged with electric power generated by regenerative braking.
The present invention can be widely applied to a configuration in which the charging device 3 is replaced with the following configuration: the battery 2 is charged by electric power of a built-in internal combustion mechanism, a fuel cell, or the like, in addition to the charging device 3; and a configuration in which the commercial power source is charged by a built-in charging device.
The electric vehicle 1 includes a driving unit 6, a display unit 7, a display control unit 8, a battery sensor 9, and the like.
The driving unit 6 is configured by various means such as a motor driven by the electric power of the battery 2, a driving wheel rotated by the motor, and a braking mechanism for controlling the rotation of the driving wheel, and supplies electric power generated by regenerative braking of the motor to the battery 2 during deceleration.
The display unit 7 is a portion for displaying vehicle information such as a vehicle speed and a travel distance, and may be an image display panel such as a liquid crystal display panel or an organic Electroluminescence (EL) display panel, for example, but may be a head-up display. And the constitution of the navigation device displaying the navigation information can also be applied.
The display control unit 8 is a part that controls the display of the display unit 7, and obtains various vehicle information such as the vehicle speed output from the controller of the electric vehicle 1, for example, and displays the vehicle information on the display unit 7.
The battery sensor 9 is configured to acquire various information necessary for charge/discharge control of the battery 2, and is configured to detect at least a terminal voltage of the battery 2, a charge/discharge current of the battery 2, and a temperature. The electric vehicle 1 controls charge and discharge using information detected by the battery sensor 9.
[ Deterioration diagnosis ]
The degradation diagnosis unit 10 is configured to detect degradation of the battery 2.
The electric vehicle 1 obtains an estimated value of the degradation state by an estimation unit 11 provided in the degradation diagnosis unit 10, and displays the estimated value as a detection result of the degradation state by a display unit 7 by a display control unit 8.
Here, the estimating unit 11 estimates the degradation state of the battery 2 using the change in the internal resistance of the battery 2. More specifically, the estimating unit 11 calculates the internal resistance from the Charge/discharge current and the terminal voltage detected by the battery sensor 9, and determines the degradation State by determining the calculated internal resistance from a standard value (initial value) in accordance with the State Of Charge (SOC) Of the secondary battery obtained from the terminal voltage Of the battery 2 detected by the Charge/discharge control.
In addition, the estimation of the degradation state is not limited thereto, and various techniques may be applied. Specifically, the internal resistance can be similarly calculated and the degradation state estimated by only charging performed by the charging device 3 of the battery 2. The SOC of the battery 2, which is detected by the battery sensor 9 and is based on the charge/discharge current, the terminal voltage, and the temperature, and which is detected by the charge/discharge control, may be loaded to a server at regular time intervals, and the server may estimate and acquire the degradation state.
Further, instead of such estimation of the degradation state by the change in the internal resistance, the degradation state may be estimated by the change in the charge capacity. At this time, the estimating unit 11 calculates a capacity change (Δah) of the battery 2 using the charge/discharge current and the terminal voltage detected by the battery sensor 9, and estimates the degradation state using a variable Δsoc divided by the corresponding SOC detected by the charge/discharge control. Also in the estimation of the degradation state by the change in the charge capacity, as in the case of the change in the internal resistance, it is possible to detect only when the battery 2 is charged by the charging device 3, and it is also possible to estimate the degradation state by the processing of the server.
The estimated value may be calculated by using a change in the increase of the terminal voltage with respect to the discharge current.
In this way, the degradation state is detected, and the degradation diagnosis unit 10 calculates the accuracy of the estimated value of the degradation state with the estimation unit 11.
The accuracy calculation method may be applied to various methods, and may be applied to, for example, a case of detection by a statistical process using a detection result such as deviation detection, a case of detection by time division for detection of internal resistance, capacity change (Δah), and variable Δsoc of SOC, or the like. In addition, when the estimated value is acquired by the processing of the server, the accuracy is calculated and acquired on the server side, but may be calculated in the estimating unit 11.
[ Display control by the display control section ]
The display control unit 8 displays the remaining amount (remaining capacity) of the battery 2 detected by the charge/discharge control and the detection result of the degradation state obtained by the degradation diagnosis unit 10 on the display unit 7 in accordance with the operation of the driver. In this display, the display control unit 8 displays the time information of the estimated time of the estimation result together.
Fig. 2 is a diagram showing a display example of the detection result.
The display control unit 8 displays a mark 21 for calling the dry cell of the battery 2 in the display area 7A of the detection result provided in the display unit 7. The 100% charging rate at the time of no deterioration is expressed as the outer shape of the mark 21, the color of the mark 21 of the dry cell is switched in the middle, and the residual amount is displayed by the boundary of the color switching. Further, the color is switched under the mark 21, and the detection result of the degradation state is displayed. The detection results of the residual amount and the degradation state are displayed as numerals at the corresponding positions of the marks 21. Therefore, in the example of fig. 2, the chargeable capacity is reduced by 11% due to degradation, and the detected residual amount shows 86% of the full charge amount when no degradation occurs.
Further, in this display, a "sign" is attached to the end of the display of the number of the degradation detection result, and a "degradation calculation date" is provided in accordance with this sign: by displaying 2019, 8, 7 days ", the time information of the estimated time is displayed by the display of the year, month, and day.
The display control unit 3 switches the display of the time information by the year, month, day, and minute and second to the display by the year, month, day, and minute and second as shown in fig. 3, in comparison with fig. 2, according to the operation of the driver.
In this way, by using the display of the time information at the estimated time of the estimation result, the electric vehicle 1 can provide more detailed information about the degradation state of the secondary battery than before, and can give the driver a sense of security, and further take appropriate measures such as replacement of the secondary battery.
In addition, various methods may be applied to display the residual amount, for example, as shown in fig. 4, by displaying the detection result of the degradation state on the upper side of the mark 21 of the dry cell, as compared with fig. 2, it is possible to display the reduction of the entire capacity ("display of MAX 89%") and further display the residual amount. In addition, in the display of fig. 4, "-MAX" is provided: and compared with the production, the display explanatory text of 11% degradation caused by degradation with time.
In addition, the time information may be displayed together with the estimated required time (diagnosis time), or alternatively or additionally, the number of samples of the estimated required data may be displayed.
Further, the display control unit 8 displays a method of estimating the degradation state according to the operation of the driver. Specifically, in the examples of fig. 3 and 4, the degradation state is displayed by using the display of "degradation detected by server analysis" and "degradation detected during charging", respectively. Thereby, more detailed degradation state related information of the secondary battery can be provided.
The display control unit 8 displays the estimation technique in this manner, and displays the estimation technique in further detail according to the operation of the driver.
Here, the detailed display of this estimation method is performed by switching the display of the display area 7A and displaying an explanatory drawing to display explanatory text in more detail. Specifically, the specification is "using a current sensor and a voltage sensor, and detecting output degradation with reference to past diagnosis results. "," measure and detect capacity deterioration based on Δah/Δsoc. "using the vehicle-mounted ECU and calculating from the voltage drop sensitivity with respect to the current at the time of assist", etc. Thus, the information on the deterioration state of the secondary battery can also be provided in more detail.
The display control unit 8 displays the degradation state in this manner, and switches the display of the accuracy of the estimation result according to the operation of the driver. More specifically, the display control section 8 switches the display and non-display of the accuracy detected by the estimation section 11 in response to the operation of the driver, and further displays the error of the estimation result due to the sensor for the estimation of the degradation state.
Here, the display of this error is performed by displaying, for each sensor, a measurement error of the sensor itself and an error of the accuracy of the degradation detection result due to this error. Specifically, the detection results are displayed, for example, "current sensor accuracy 3%, degradation detection error 1.5%", "voltage sensor accuracy 5%, degradation detection error 2.5%", "temperature sensor accuracy 2%, degradation detection error 1%", and the like. The display method is not limited to this, and various display methods can be applied. Thus, in the electric vehicle 1, the degradation state related information can be provided in further greater detail.
The display control unit 8 displays the degradation state in this manner, and selects any one of the display items by the operation of the touch panel provided on the display unit 7, and then displays the explanatory text of the selected display item.
Fig. 5 and 6 are diagrams showing examples of the display of the explanatory text, and fig. 5 is an example of the display of the text when the degradation is selected by the driver, and fig. 6 is an example of the display of the text when the degradation calculation date is selected by the driver.
The display control unit 8 displays a message for confirming the content of the query of the driver as indicated by symbols Q1 and Q2, and then displays the corresponding description as indicated by symbols A1, A2, and A3, thereby providing the description in the form of a dialogue. The explanatory text may be provided by sound.
The display control unit 8 displays the degradation state in this manner, and switches the number of bits of the display of the estimation result according to the operation of the driver. More specifically, for example, in the display of the percentage of the degradation state, the number of bits below the decimal point is switched according to the operation of the driver. Thereby, the electric vehicle 1 improves the convenience of use for the driver.
The display control unit 8 displays the degradation state in this manner, and switches the display of the explanatory text according to the operation of the driver. More specifically, the display control section 8 starts displaying the presentation text in response to the operation of the driver, and further stops the display. Alternatively or additionally, the detailed description and the simple description may be switched, or the long description text and the short description text may be switched. Thus, the electric vehicle 1 can improve the convenience of use for the driver.
Further, the display control unit 8 displays the degradation state in this manner, and switches the display of the accuracy of the estimation result according to the operation of the driver. More specifically, the display control section 8 switches between the display and the non-display of the precision in response to the operation of the driver.
[ Information Notification of display switching ]
The display control unit 8 notifies the server of the estimation result, the number of bits of the estimation result, the explanatory text of the estimation result, and the display of the accuracy, which are obtained by the estimation unit 11 selected by the driver, together with the current position information at each selection time. Thus, the server accumulates the notifications and analyzes the accumulated information, thereby enabling various systems such as development of subsequent vehicles.
According to the above configuration, the estimation result obtained by the estimation section that estimates the degradation state of the secondary battery is displayed together with the time information of the estimation time of the estimation result, whereby the degradation state related information of the secondary battery can be provided in more detail.
And, an estimation method of estimating the result according to the operation of the driver is further displayed, whereby the degradation state related information can be provided in more detail.
And, an error of the estimation result due to the sensor for estimation of the degradation state is further displayed, whereby the estimation accuracy of the degradation state is further displayed, whereby the degradation state related information can be provided in more detail.
Further, the number of bits of the display of the estimation result is switched, the display of the explanatory text of the estimation result is further switched, and the display of the accuracy is switched, whereby the convenience of use for the driver can be improved.
