Description

Title of the invention: METHODS AND SYSTEMS FOR MANAGING BATTERY USAGE DATA FOR AN ELECTRIC VEHICLE Field of the invention

[0001] The invention relates generally to methods and systems for managing battery usage data for an electric vehicle, and, more particularly, to methods and management systems that can obtain usage data from at least one battery when predetermined conditions are triggered by an electric vehicle. Description of the state of the art

[0002] Recently, with increasing awareness of environmental protection and technological advances in electric vehicles, the development of electric vehicles to replace traditional fossil fuel-powered vehicles has gradually become an important objective in the automotive sector, thus making electric vehicles increasingly popular. To increase the range and willingness to use electric vehicles, many countries and cities have begun installing charging stations and battery power stations in public places to allow for the charging or swapping of batteries for electric vehicles and / or electric motorcycles, thereby making the use of electric vehicles more convenient.

[0003] With advances in information technology, the trend in vehicle development is toward becoming increasingly intelligent. Beyond basic transportation functions, improved safety and more peripheral features have also become development goals in the industry. Encouraged by government subsidy policies, many people have begun trying to purchase and use electric vehicles as a means of transportation. Generally speaking, electric vehicles are equipped with a greater number of electronic components / devices and can be combined with users' mobile devices to offer more personalized applications and experiences.

[0004] Generally, the battery is the most important component of an electric vehicle, as it provides the electrical energy needed to move the vehicle. Batteries remain one of the most significant costs of electric vehicles due to the insurmountable challenges associated with battery technology. On the other hand, the high cost of batteries is also one of the main reasons for the high maintenance costs of Electric motorcycles. If different charging methods can be planned according to user needs, or even if different suppliers can be introduced to join the electric vehicle supply chain, it may be possible to moderately reduce the overall maintenance cost of electric motorcycles and increase user willingness to adopt them. For example, if the cost can be calculated based on users' actual battery usage data, this can also increase opportunities for users with different lifestyles to adopt electric motorcycles.

It determines whether a predetermined condition in the electric vehicle is triggered. When the predetermined condition in the electric vehicle is triggered, a battery measurement unit of the electric vehicle obtains the battery usage data for the corresponding battery from the battery management unit.

[0007] An embodiment of a battery usage data management system for an electric vehicle adapted for an electric vehicle includes a battery system and a battery measurement unit. The battery system includes at least one battery and a management unit. At least one battery supplies electrical energy to the electric vehicle.

When the electric vehicle connects 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 by the electric vehicle, and the battery usage data corresponding to the battery is transmitted from the mobile device to a remote server via a second network.

[0009] In certain embodiments, it is determined whether the electric vehicle has not connected to a mobile device for a predetermined period. When the electric vehicle has not connected to the mobile device for a period exceeding the predetermined period, a prompt is issued via an output unit of the electric vehicle, the output unit comprising a display unit or a sound output unit.

[0010] In certain embodiments, it is determined whether the electric vehicle has not been connected to a mobile device for a predetermined period. When the electric vehicle has not been connected to the mobile device for a period exceeding the predetermined period, the output power of the battery or the power of a motor group of the electric vehicle is limited by the electric vehicle.

[0011] In certain embodiments, it is determined whether the electric vehicle has not been connected to a mobile device for a period exceeding a specified time. When the electric vehicle has not been connected to the mobile device for a period exceeding the specified time and the available space in the electric vehicle's storage unit is insufficient, the historical battery usage data from multiple storage units is merged and the battery usage data is recorded.

[0012] In some embodiments, the electric vehicle includes a trunk lid or a seat cover, and determining whether the predetermined condition in the electric vehicle is triggered or not involves determining whether a state corresponding to the trunk lid or the seat cover changes, and when the state corresponding to the trunk lid or the seat cover changes, it is determined that the predetermined condition is triggered.

[0013] In some embodiments, determining whether the predetermined condition is triggered or not in the electric vehicle involves determining whether a state of an ignition switch or a power switch of the electric vehicle changes, and when the state of the ignition switch or the power switch changes, it is determined that the predetermined condition is triggered.

[0014] In some embodiments, determining whether the predetermined condition is triggered in the electric vehicle involves determining whether the battery starts or stops supplying electrical power to the electric vehicle, and it is determined that the predetermined condition is triggered when the battery starts or stops supplying electrical power to the electric vehicle.

[0015] The methods for managing battery usage data for an electric vehicle can take the form of program code incorporated in a Tangible support. When the program code is loaded and executed by a machine, the machine becomes a device for putting the disclosed process into practice. Brief description of the drawings
