Description

Technical Field

[0001] The present invention relates to a battery usage data management method and system for an electric vehicle, and more particularly to a management method and system for obtaining usage data from a battery when the electric vehicle triggers a predetermined condition. Background Art

[0002] In recent years, with the rise of environmental awareness and the advancement of electric vehicle technology, the development of electric vehicles powered by electricity to replace traditional vehicles powered by fossil fuels has gradually become an important goal in the automotive field, making electric vehicles more and more popular. In order to increase the range and willingness to use electric vehicles, many countries or cities have begun to plan to set up charging stations and battery energy stations in public places to provide electric vehicles and / or electric motorcycles for charging or battery replacement, making the use of electric vehicles more convenient.

[0003] With the advancement of electronic information, the trend of vehicle development is becoming more and more intelligent. In addition to the basic carrying function, the improvement of safety and more peripheral application functions has also become an issue that the industry is working hard to develop. Encouraged by the government's subsidy policy, many people have also begun to try to buy and use electric vehicles as a means of transportation. Generally speaking, electric vehicles are equipped with more electronic components / devices and can be combined with the user's mobile device to provide more personalized applications and experiences.

[0004] Generally speaking, batteries are the most important component of electric vehicles, providing the electric energy required for electric vehicles to move. As battery technology is difficult to overcome, batteries remain one of the most important costs of electric vehicles. On the other hand, the high cost of batteries is also one of the main reasons for the high service costs of electric motorcycles. If different charging modes can be planned according to user needs, or even different suppliers can be introduced to join the electric vehicle ecosystem, the overall service costs of electric motorcycles may be moderately reduced, further increasing users' willingness to adopt electric motorcycles. For example, if the cost can be calculated based on the user's actual battery usage data, it will also increase the chances of users with different attributes adopting electric motorcycles. Summary of the invention

[0005] Therefore, an object of the present invention is to provide a battery usage data management method for an electric vehicle that can overcome the above problems.

[0006] Therefore, the battery usage data management method of an electric vehicle of the present invention is applicable to an electric vehicle having at least one battery. First, while the battery provides the electric vehicle with electric energy, a management unit corresponding to the battery continuously records a battery usage data of the corresponding battery. Then, it is detected whether a predetermined condition in the electric vehicle is triggered. When the predetermined condition in the electric vehicle is triggered, a battery metering unit of the electric vehicle obtains the battery usage data of the corresponding battery from the management unit of the battery.

[0007] In some embodiments, it is determined whether the electric vehicle is connected to a mobile device via a first network. When the electric vehicle is connected to the mobile device via the first network, the battery usage data corresponding to the battery is transmitted to the mobile device via the first network. The mobile device transmits the battery usage data corresponding to the battery to a remote server via a second network.

[0008] In some embodiments, it is determined whether the electric vehicle has not been connected to a mobile device for more than a predetermined period of time. When the electric vehicle has not been connected to the mobile device for more than a predetermined period of time, an output unit of the electric vehicle issues a prompt. The output unit includes a display unit or a sound unit.

[0009] In some embodiments, it is determined whether the electric vehicle has not been connected to a mobile device for more than a predetermined period of time. When the electric vehicle has not been connected to the mobile device for more than the predetermined period of time, the electric vehicle limits the power output of the battery or limits the output of a motor unit of the electric vehicle.

[0010] In some embodiments, it is determined whether the electric vehicle has not been connected to a mobile device for more than a specific period of time. When the electric vehicle has not been connected to the mobile device for more than the specific period of time and the available space of a storage unit of the electric vehicle is insufficient, multiple historical battery usage data in the storage unit are merged and recorded.

[0011] In some embodiments, the electric vehicle has a trunk lid or a seat cushion cover, and detecting whether the predetermined condition is triggered in the electric vehicle is to determine whether the trunk lid or the seat cushion cover is opened. When the trunk lid or the seat cushion cover is opened, it is determined that the predetermined condition is triggered.

[0012] In some embodiments, detecting whether the predetermined condition in the electric vehicle is triggered is to determine whether a power switch of the electric vehicle is turned off, and determining that the predetermined condition is triggered when the power switch is turned off.

[0013] In some embodiments, detecting whether the predetermined condition in the electric vehicle is triggered is determining whether the battery stops supplying power to the electric vehicle, and determining that the predetermined condition is triggered when the battery stops supplying power to the electric vehicle.

[0014] Another object of the present invention is to provide a battery usage data management system for an electric vehicle.

[0015] Therefore, the battery usage data management system of the electric vehicle of the present invention is applicable to an electric vehicle, and includes a battery system and a battery metering unit. The battery system includes at least one battery and a management unit. The battery provides electrical energy to the electric vehicle. The management unit continuously records a battery usage data corresponding to the battery during the period when the battery provides electrical energy to the electric vehicle. The battery metering unit detects whether a predetermined condition in the electric vehicle is triggered, and when the predetermined condition in the electric vehicle is triggered, the management unit of the battery obtains the battery usage data corresponding to the battery.

[0016] The above method of the present invention may exist in the form of program code. When the program code is loaded and executed by a machine, the machine becomes a device for implementing the present invention. Therefore, another object of the present invention is to provide a computer program product as described above.

[0017] Therefore, the computer program product of the present invention is loaded into a machine to execute a battery usage data management method for an electric vehicle, and is applicable to an electric vehicle having at least one battery. The computer program product includes a first program code, a second program code, and a third program code. The first program code is used to enable a management unit of the battery to continuously record a battery usage data of the battery during the period when the battery provides electric energy to the electric vehicle. The second program code is used to detect whether a predetermined condition in the electric vehicle is triggered. The third program code is used to enable a battery metering unit of the electric vehicle to obtain the battery usage data of the battery from the management unit of the battery when the predetermined condition in the electric vehicle is triggered.

[0018] The effect of the present invention is that: by using the battery usage data management method and system of the electric vehicle of the present case, the usage data can be obtained from the battery when the electric vehicle triggers a predetermined condition, and subsequent management can be performed, thereby increasing the flexibility of the application of the electric vehicle and its battery.
