Abstract
Claims
1. A vehicle equipped with a display device and a control device, The vehicle further comprises a power storage device that houses a battery and components other than the battery, The control device is configured to estimate the degree of battery degradation and to control the display device so that a parameter indicating the estimated degree of battery degradation and a first mileage expressed in a predetermined format are displayed. The control device is configured to control the display device so that, when it receives a signal indicating that the part has been replaced, the second mileage is displayed instead of the first mileage. The first mileage is the cumulative mileage traveled by the vehicle after the parameter update. A vehicle in which the second mileage is the maximum value in the predetermined form.
2. The control device includes a storage device that stores component information indicating the state of the component, The control device is configured to check the status of the component and update the component information. The control device is Using the aforementioned part information, determine whether the part needs to be replaced. The system is configured to request the user to replace the aforementioned part if it is determined that the aforementioned part needs to be replaced. The vehicle according to claim 1, wherein the control device is configured to initialize the component information when it receives the signal.
3. The control device is configured to update the parameters each time a predetermined condition is met. The control device is configured to control the display device so that when the parameter is updated, a third mileage is displayed instead of the first mileage or the second mileage. The vehicle according to claim 1 or 2, wherein the third mileage is the minimum value in the predetermined form.
4. The control device is housed in the energy storage device together with the battery and the components. The component includes at least one of a voltage sensor for detecting the voltage of the battery, a current sensor for detecting the current of the battery, and a temperature sensor for detecting the temperature of the battery. The control device is configured to estimate the degree of battery degradation using at least one detected value from the voltage sensor, the current sensor, and the temperature sensor. The vehicle is configured to be able to run using the power output from the battery, The aforementioned predetermined format is a 16-bit binary format. The vehicle according to claim 1 or 2, wherein the second mileage is 65,535 km.
5. The aforementioned parameter is the capacity retention rate. The control device is configured to control the State of Control (SOC) of the battery within a range from the lower limit of SOC to the upper limit of SOC. The vehicle according to claim 1 or 2, wherein the control device is configured to estimate the capacity of the battery from the lower limit of the SOC to the upper limit of the SOC, and to calculate the capacity retention rate based on the estimated capacity.
