Battery Identification Pin Loopback Detection for Flexible Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying electric batteries within a system, such as an electric vehicle, do not accurately determine the location of each battery, leading to complex management and limited flexibility in battery usage.
Innovation Solution
A method using an identification interface with multiple pins, where at least one pin can be connected to another to allocate an identifier, by polarizing and testing each pin with a predetermined potential to detect loopbacks and determine the identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery location is determined in the factory beforehand, then battery management becomes more complex in both factory and vehicle, but battery identifier can be allocated
Solution Approach 1:
The patent transforms the static factory-allocated identification system into a dynamic system where identifiers are determined by physical pin connections. The identification interface allows pins to be connected or disconnected based on battery location, enabling flexible reconfiguration without complex management systems. This resolves the contradiction by making the system adaptable rather than requiring complex pre-management.
Solution Approach 2:
The battery system automatically determines its own identifier through physical pin connections at the identification interface. The microcontroller detects which pins are connected and autonomously generates the corresponding binary identifier, eliminating the need for external factory configuration or complex management systems. The system self-configures based on its physical installation state.
2Reliability
If battery location is determined in the factory beforehand, then identifier can be allocated, but flexibility during use is limited and battery cannot be used in locations other than allocated
Solution Approach 1:
The identification system dynamically adapts to battery location through physical pin connections. Each battery location in the vehicle has a unique pin connection configuration, and the system automatically detects these connections to determine the battery's identifier and location. This enables batteries to be freely moved between locations without reconfiguration, as the system adapts to the new physical arrangement.
Solution Approach 2:
The patent changes the identification parameter from a fixed factory-assigned value to a dynamically determined value based on pin connection states. The microcontroller reads the connection status of multiple pins and converts this physical state into a binary identifier, allowing the same battery to have different identifiers depending on its installation location, thereby achieving full flexibility.
3Adaptability or versatility
If identification pins are connected to allocate identifier, then flexibility in battery use is enhanced, but complexity of detecting pin connections increases
Solution Approach 1:
The patent replaces complex mechanical or software-based identification systems with a simple electrical connection detection mechanism. The microcontroller uses basic electrical tests (measuring resistance or voltage) on the identification pins to detect connections, converting a potentially complex identification problem into a simple electrical measurement task that is easily automated.

AI summary
A method for identifying an electrical battery provided with an electrical interface, called the identification electrical interface, including several pins, called the identification pins, at least one of the identification pins being connectable to at least one other identification pin to assign an identifier to the battery, the method includes at least one iteration of a step of reading the identifier, including the following operations carried out alternately for each of the identification pins: polarising the identification pin at a predetermined electric potential (V1), called the test potential; and detecting whether or not the test potential (V1) is present on each of the other identification pins in order to identify the identification pins which are looped together.
