Battery Swapping Station BMS Update Before Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery swapping technology faces inefficiencies in charging time, which negatively impacts user experience due to outdated software versions of battery management units, requiring suspended charging processes for updates.
Innovation Solution
A method and system where a server at the battery swapping station acquires and updates the software version of a power battery's management unit to a newer version before charging, utilizing wireless communication for efficient software updates and charging, ensuring compatibility and reducing overall charging time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software update is performed during charging process, then software version is updated, but charging process is suspended causing longer charging time
Solution Approach 1:
The system performs software updates before the charging process begins. The server checks the software version of the battery management unit, and if it is outdated, the update is executed in advance. This preliminary action ensures that the charging process is not suspended, thereby resolving the contradiction between maintaining updated software and minimizing charging time.
2Loss of time
If software update is performed before charging, then charging time is reduced, but system complexity increases due to version checking and update management
Solution Approach 1:
The battery management unit automatically checks its own software version and performs self-updates when needed. The server provides the update capability, but the actual update execution is handled autonomously by the battery management unit without requiring complex manual intervention or sophisticated version management systems.
Solution Approach 2:
The system implements a feedback mechanism where the battery management unit reports its software version to the server, which then determines whether an update is needed. This simple feedback loop enables automatic version management without requiring complex system architecture.
3Reliability
If charging process is suspended for software update, then software compatibility is ensured, but user experience deteriorates due to extended duration
Solution Approach 1:
Software updates are executed before the charging process begins, ensuring that the battery management unit has the latest compatible software version. This preliminary update action guarantees software compatibility while allowing the charging process to proceed without interruption, thereby maintaining good user experience.

AI summary
Embodiments of the present application provide a server of a battery swapping station, a charging method and system for a battery, a device and a medium. The method is applied to a server of a battery swapping station, and the method includes: acquiring version information of a first software version after a vehicle mounted with a power battery arrives at the battery swapping station, wherein the first software version is a software version of a first battery management unit of the power battery; controlling, under a condition that the version information of the first software version is lower than version information of a second software version stored in the server, a second battery management unit of the battery swapping station to update the first software version of the first battery management unit to the second software version.
