Solution Overview
Problem
Identifying the type of battery cell within a vehicle battery pack without physically opening it is challenging due to similar external characteristics of different battery types, which can lead to uncertain operational control and reduced efficiency or durability.
Innovation Solution
A system and method where a battery controller uses a connection module with active and non-active pins to receive sensor signals from the battery pack, analyzing the pin arrangement to determine the battery cell type, make, model, and manufacturer, allowing for optimized operational procedures without physically opening the pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery controller uses external characteristics to identify battery cell types, then the identification process is simple, but the identification accuracy is low due to similar external characteristics of different battery types
Solution Approach 1:
The patent introduces a connection module with pin arrangement as an intermediary element that provides distinctive identification patterns for different battery cell types. The pin arrangement serves as a mediator between the battery pack and controller, enabling accurate type identification without requiring physical opening of the battery pack or complex analysis of similar external characteristics.
2Measurement precision
If the battery pack is physically opened to confirm battery cell types, then the identification accuracy is high, but the device complexity and time required increase
Solution Approach 1:
The patent extracts the identification function from the physical battery cell structure and relocates it to the connection module's pin arrangement. This extraction allows the battery cell type identification to be performed externally through the connection module without requiring physical access to or opening of the battery pack, thereby maintaining high identification accuracy while reducing device complexity and inspection time.
3Reliability
If the battery controller implements specialized operational control for different battery cell types, then the operational efficiency and durability are improved, but the control system complexity increases
Solution Approach 1:
The patent implements preliminary action by having the battery controller identify the battery cell type through the connection module's pin arrangement before initiating operational control. This preliminary identification allows the controller to pre-load or select the appropriate control strategy specific to the identified battery cell type, thereby achieving optimized operational efficiency and durability without requiring complex real-time decision-making or multiple control systems.

AI summary
A method, apparatus, and system are disclosed for analyzing a vehicle battery system of a hybrid or electric vehicle that includes a battery pack and a battery controller. More specifically, a battery controller is disclosed for determining battery identification information of the battery pack based on a configuration of active and non-active pins in a connection module between the battery pack and the battery controller. It follows that the battery controller may identify the battery pack type in an efficient manner that does not require any additional components. The battery controller may further reference the battery identification to implement a battery operational strategy that may better realize an efficiency or durability of the identified battery.
