Battery Swapping ID Assignment for In-Vehicle Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery swapping processes for electric vehicles are inefficient due to manual configuration of communication IDs, which increases the time required for swapping and can lead to battery degradation, especially with rapid charging techniques that reduce battery life.
Innovation Solution
A system and method for automatically assigning static or dynamic IDs to charged batteries based on the ID information of discharged batteries, facilitating communication within the vehicle's network without manual user intervention, thereby reducing swapping time and eliminating the need for manual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of communication ID is performed for each charged battery, then communication between battery and vehicle controller is established, but swapping time increases and operational efficiency decreases
Solution Approach 1:
The charged battery autonomously performs self-configuration by automatically assigning its communication ID based on its own identification information and the vehicle controller's requirements, eliminating the need for manual configuration and reducing swapping time while ensuring reliable communication
Solution Approach 2:
The battery management system pre-configures communication parameters and ID assignment rules before the battery is installed in the vehicle, so that when the battery is swapped in, communication is immediately established without requiring time-consuming manual configuration during the swapping process
2Loss of time
If rapid charging techniques are used to reduce recharging time, then recharging time decreases to 10-30 minutes, but battery life decreases due to degradation
Solution Approach 1:
The patent extracts the charging function from the vehicle operation cycle by implementing battery swapping, where the discharged battery is removed and replaced with a pre-charged battery, avoiding the need for time-consuming recharging that degrades battery life while maintaining continuous vehicle operation
Solution Approach 2:
The system changes the operational parameter from rapid charging (high current that causes degradation) to battery swapping (physical replacement), achieving fast replenishment of energy without subjecting the battery to degrading charging conditions, thus preserving battery life
3Productivity
If automated ID assignment is implemented for charged batteries, then swapping time decreases and efficiency increases, but system complexity increases
Solution Approach 1:
The battery management system performs multiple functions including battery monitoring, communication protocol management, and automated ID assignment within a single integrated system, eliminating the need for separate complex ID configuration systems and reducing overall system complexity while maintaining high swapping efficiency

AI summary
Battery swapping includes receiving a swap request for swapping a set of discharged batteries in a vehicle with a set of charged batteries at a charging station. Based on a battery swapping count provided by a user, the set of charged batteries including first and second subsets of charged batteries are selected from a plurality of charged batteries available at the charging station. At least one of a static ID or a dynamic ID is assigned to each charged battery. Each charged battery in the first and second subsets is configured as a master battery and a slave battery by integrating at least the respective static and dynamic ID in a corresponding battery management system of each charged battery, respectively, for facilitating in-vehicle battery communication. Further, the set of charged batteries is released from a charging and storing platform to a swapping platform for swapping.
