Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power supply is continuously provided to electronic devices when the vehicle is parked, then the devices can operate normally, but the battery discharge amount increases and may lead to starting failure
Solution Approach 1:
The battery management apparatus performs preliminary assessment of battery state (SoC) and remote service usage patterns before determining the power supply cut-off time point. By predicting future battery status and user behavior in advance, the system sets an optimal cut-off time that prevents starting failure while minimizing discharge loss.
Solution Approach 2:
The power supply cut-off time point is not fixed but dynamically adjusted based on real-time battery state information and historical remote service usage data. The system adapts the cut-off timing to match actual user behavior patterns, making the power management strategy flexible and responsive to changing conditions.
2Loss of energy
If power supply is cut off early to prevent battery discharge, then energy loss is reduced, but device operation may be interrupted during remote service usage
Solution Approach 1:
The system continuously monitors battery state information and compares it against predicted future status. It also tracks remote service usage patterns to understand when devices are actually needed. This feedback loop enables the system to optimize the cut-off time point, ensuring devices remain operational during actual usage while preventing discharge below safe thresholds.
Solution Approach 2:
The system changes the cut-off time point parameter based on varying battery state conditions and usage patterns. Instead of using a fixed cut-off threshold, the system adjusts the timing parameter dynamically to balance energy conservation with operational reliability requirements.
3Reliability
If the battery management apparatus monitors and adjusts cut-off time based on remote service usage data, then starting failure is prevented, but device complexity increases
Solution Approach 1:
The battery management apparatus performs multiple functions: it monitors battery state, analyzes remote service usage patterns, predicts future battery status, and determines optimal cut-off timing. By consolidating these diverse functions into a single integrated system, the patent reduces overall system complexity compared to having separate systems for each function.
Solution Approach 2:
The system uses its own collected data about remote service usage patterns to automatically optimize its power management strategy. It self-adjusts the cut-off time point based on its own monitoring of battery state and usage information, eliminating the need for external manual configuration or complex external control systems.

AI summary
A vehicle receives SoC information of the battery when the vehicle is in a parked state, determines whether a charged amount of the battery is lower than or equal to a preset charged amount based on the received SoC information of the battery, determines whether a current time is included in a use time zone based on use time information of the remote service when it is determined that the charged amount of the battery is lower than or equal to the preset charged amount, adjusts a cut-off time point of power supply of the battery in response to whether the current time is included in the use time zone, and transmits a power supply cut-off command of the battery to the battery management apparatus.
