Battery Control Circuit Ship Mode Leakage Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing and configuring batteries in electronic devices during manufacturing are inefficient, leading to increased delivery costs and potential battery damage due to overdischarge during transportation, especially for high-capacity batteries, which require a low power level to prevent overdischarge but struggle to re-enter ship mode for reconfiguration.
Innovation Solution
A control circuit module with a first check circuit, a first discharge circuit, and a controller that enables the battery to enter ship mode without external machinery, preventing leakage currents from affecting the battery and ensuring it remains in ship mode, thus avoiding overdischarge during storage or transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If batteries are delivered separately from electronic devices, then delivery costs increase, but batteries can be configured independently
Solution Approach 1:
The patent combines the battery configuration function directly into the electronic device's control circuit module, allowing the battery to be configured through the electronic device itself rather than requiring separate configuration machinery. This merging enables batteries to be delivered together with electronic devices while still allowing proper configuration.
2Reliability
If high-capacity batteries maintain low power level during transportation, then they comply with aviation laws, but they cannot easily re-enter ship mode for reconfiguration
Solution Approach 1:
The patent implements a discharge circuit that is enabled before the battery enters ship mode to release leakage current, and is disabled after ship mode is entered. This preliminary action of managing leakage current allows the battery to successfully enter and maintain ship mode even at low power levels required by transportation laws.
