Description

Battery charging management method and system for electric vehicles, and computer program products

The present invention relates to a battery management method and system, and in particular to a method and system for managing the battery replenishment, such as charging or battery replacement, of an electric vehicle.

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 improve the range and willingness of 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 cars and/or electric motorcycles with charging or battery exchange, making the use of electric vehicles more convenient.

Generally speaking, batteries are one of the most important costs for operators, and rechargeable batteries have a limited life cycle. For some electric vehicles, such as electric motorcycles, when the battery power is insufficient, the power of individual batteries varies greatly, and/or the life cycle of individual batteries varies greatly, if the user uses a combination of these batteries to start the electric vehicle, it will affect the function or life of the vehicle or the battery itself.

On the other hand, the high cost of batteries is also one of the main reasons for the high service costs of electric scooters. If different charging modes can be planned according to user needs, or even different suppliers are introduced to join the electric vehicle ecosystem, the overall service costs of electric scooters may be reduced appropriately, further increasing users’ willingness to adopt electric scooters.

In view of this, the present invention provides a battery charging management method and system that can be used in electric vehicles.
