Battery Swap Control for Vehicle-Compatible Battery Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery swap systems face challenges in selecting a suitable replacement battery for vehicles, leading to a possibility of using batteries that are not compatible with the target vehicle.
Innovation Solution
A battery swap system that includes a vehicle-side control device and a battery swap apparatus, where the vehicle-side control device selects a second battery for swapping by using battery installation information, electrical requirement information, and battery information, prioritizing factors such as battery installation position, voltage, output power, and capacity.

Engineering Contradiction Analysis
1Reliability
If the battery electric vehicle sends only basic battery type information to the battery charging station, then the communication process is simple, but the battery charging station cannot accurately determine battery compatibility, leading to potential selection of unsuitable replacement batteries
Solution Approach 1:
The vehicle-side control device performs preliminary actions by collecting and analyzing multiple battery parameters (installation position, placement direction, voltage, output power, capacity) before the battery swap request is sent. This preliminary information preparation ensures that the battery charging station can accurately identify compatible replacement batteries without requiring complex real-time processing during the swap operation.
Solution Approach 2:
The system implements feedback by having the battery charging station send battery information to the vehicle-side control device, which then determines compatibility based on multiple parameters. The vehicle-side control device uses this feedback information to make an informed selection decision, ensuring that only compatible batteries are swapped, thereby improving reliability through iterative verification.
2Reliability
If the vehicle-side control device uses multiple battery parameters (installation position, voltage, output power, capacity) for selection, then the accuracy of battery compatibility determination is improved, but the selection process becomes more complex
Solution Approach 1:
The vehicle-side control device performs self-service by automatically collecting battery information from the battery charging station and independently determining compatibility based on multiple parameters. The system autonomously compares the vehicle's battery requirements with the available replacement batteries, making the selection process self-contained and reducing manual intervention complexity while maintaining high accuracy.
Solution Approach 2:
The system applies parameter changes by dynamically evaluating multiple battery parameters (installation position, placement direction, voltage, output power, capacity) rather than relying on a single fixed criterion. This multi-parameter approach allows the system to adapt to different battery configurations and vehicle requirements, improving compatibility determination accuracy while the automated process manages the complexity of evaluating multiple variables.

AI summary
A battery swap system includes a vehicle-side control device and a battery swap apparatus. The battery swap apparatus has at least one replacement battery in stock, and is configured to swap out a first battery installed in a vehicle for a second battery out of the at least one replacement battery. The vehicle-side control device is configured to select the second battery from the at least one replacement battery using battery installation information, electrical requirement information, and battery information. The battery installation information is information regarding either or both of a battery installation position and a battery placement direction in the vehicle. The electrical requirement information is information regarding electrical characteristics required of the second battery.
