Battery Swap Battery Selection for Vehicle Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery swap systems face challenges in selecting a replacement battery that is not suitable for the target vehicle, leading to inefficiencies and potential compatibility issues.
Innovation Solution
A battery swap system that includes a vehicle-side control device for selecting a replacement battery based on battery installation information, electrical requirement information, and battery information, prioritizing factors such as voltage, output power, and capacity to ensure compatibility with the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
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 may select an incompatible battery for swapping
Solution Approach 1:
The vehicle-side control device performs preliminary filtering of replacement batteries based on battery installation information and electrical requirement information before the battery swap apparatus selects a battery. This preliminary action ensures compatibility is verified in advance, preventing selection of incompatible batteries while maintaining simple communication protocols.
2Measurement precision
If the vehicle-side control device uses multiple criteria (battery installation information, electrical requirement information, and battery information) to select a replacement battery, then the selection accuracy improves, but the selection process complexity increases
Solution Approach 1:
The battery selection process is segmented into distinct evaluation dimensions: battery installation information (position and direction), electrical requirement information (voltage, output power, capacity), and battery information. The vehicle-side control device evaluates each dimension separately and integrates the results, making the complex selection process more manageable and systematic.
3Adaptability or versatility
If the battery swap apparatus provides all replacement batteries in stock without pre-filtering, then the vehicle-side control device has more options to choose from, but the time required for selection increases
Solution Approach 1:
The vehicle-side control device receives battery information for all replacement batteries in stock and performs preliminary filtering based on battery installation information and electrical requirement information before final selection. This preliminary action maintains the availability of all options while significantly reducing the time required for the vehicle-side control device to evaluate and select the most suitable battery.

AI summary
A battery swap system (1) includes a vehicle-side control device (203) and a battery swap apparatus (100). The battery swap apparatus (100) has at least one replacement battery (101) in stock, and is configured to swap out a first battery (201) installed in a vehicle (200) for a second battery (101) out of the at least one replacement battery (101). The vehicle-side control device (203) is configured to select the second battery (101) from the at least one replacement battery (101) 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 (200). The electrical requirement information is information regarding electrical characteristics required of the second battery (101).
