Battery Module Shipping Mode for Surge Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Batteries in electronic devices face issues of power surges and leakage current when detached and reattached, leading to potential damage and power waste, as they immediately start supplying power upon reconnection, and existing solutions require operator intervention or external commands to manage these conditions.
Innovation Solution
A battery module with a connection unit and determining unit that automatically enters a shipping mode when detached from an electronic device, stopping power supply and reducing power consumption, which can be triggered by electrical signal conditions or a predetermined time, thereby preventing surges and improving safety and endurance.

Engineering Contradiction Analysis
1Speed
If the battery immediately supplies power upon reconnection to the electronic device, then the battery can provide power without delay, but a surge is generated that may damage the electronic device
Solution Approach 1:
The battery module performs preliminary detection of its operational state (normal mode vs. power interrupt mode) before reconnection occurs. The determining unit checks whether the battery is in the power interrupt mode upon detection of connection establishment, and if so, controls the battery to enter shipping mode temporarily. This preliminary action prevents surge generation by avoiding immediate power supply in conditions where it would be harmful, while still enabling quick power resumption once the shipping mode timeout expires or conditions change.
2Reliability
If the battery continuously generates leakage current when mounted on the electronic device, then the battery remains ready to supply power, but additional battery power waste is caused
Solution Approach 1:
The battery module dynamically adjusts its operational state based on real-time detection of connection status and operational mode. When the determining unit detects that the battery is in power interrupt mode and connected to an electronic device, it automatically transitions the battery to shipping mode, which reduces or eliminates leakage current. This dynamic state adjustment allows the system to maintain reliability when needed while minimizing energy waste during detached or transitional states, optimizing the balance between readiness and power conservation.
3Reliability
If operator intervention or external commands are required to manage battery power modes, then power mode control can be precisely managed, but operation complexity increases
Solution Approach 1:
The battery module incorporates a determining unit that automatically detects the battery's operational state and connection status, and autonomously controls transitions between normal mode, power interrupt mode, and shipping mode without requiring external commands or operator intervention. The system self-manages the power mode selections based on internal state detection and connection events, thereby maintaining precise power mode control while significantly improving ease of operation. The battery essentially serves itself by making intelligent decisions about its own power state management.
