Partial Battery Power Controller for Volatile Memory Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery backup devices for volatile memory systems consume high power and require long charging times due to high-capacity batteries, leading to potential data loss if external power is interrupted before charging is complete.
Innovation Solution
A battery backup device equipped with a partial battery power controller that disconnects power from components one at a time as data backup is completed, allowing the use of lower-capacity batteries and reducing power consumption and charging time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If high-capacity batteries are used to provide sufficient power for volatile memory backup, then the backup power duration is extended, but power consumption increases and charging time becomes long
Solution Approach 1:
The patent segments the backup power supply into multiple lower-capacity batteries instead of using a single high-capacity battery. The power controller manages these segmented batteries individually, switching between them as needed. This segmentation allows the system to achieve the required backup duration while using batteries with lower individual capacities, thereby reducing power consumption and charging time for each battery unit.
2Reliability
If high-capacity batteries are used to ensure sufficient backup power, then the reliability of data backup is improved, but the charging time becomes long
Solution Approach 1:
The backup power system is divided into multiple smaller battery units that can be charged and replaced more quickly than a single large battery. The power controller manages these segmented batteries, ensuring that at least one battery is available when needed. This segmentation reduces the charging time for each individual battery while maintaining the overall reliability of the backup power supply.
Solution Approach 2:
The system performs preliminary charging of multiple smaller batteries in advance, so that when external power is lost, already-charged batteries are immediately available for backup operations. This preliminary action ensures that the batteries are ready before needed, reducing the effective charging time required at the moment of power failure.
3Reliability
If high-capacity batteries are used to provide continuous backup power, then the backup power availability is maintained, but the device complexity increases
Solution Approach 1:
The patent divides the battery system into multiple independent, smaller battery units with standardized interfaces. The power controller manages these segmented batteries through a systematic approach, switching between them based on charge status and backup needs. This segmentation simplifies individual battery design and management while achieving the same overall reliability as a single large battery system.
