Metal Hydrogen Battery Rack Activation With Alternating Charge-Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The activation process for batteries, particularly metal hydrogen batteries, is time-consuming, power-intensive, and costly, requiring specialized equipment and causing logistical challenges during production and deployment, which hinders the widespread adoption of rechargeable batteries for grid-scale energy storage.
Innovation Solution
A coordinated activation method is employed where two energy rack systems are activated in alternating charge and discharge cycles, reducing the power draw from the grid by leveraging one system's discharge to power the other's charge, and incorporating fault detection and recovery mechanisms to ensure efficient on-site activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional activation procedures are used for battery systems, then batteries can be activated and ready for use, but the process requires considerable time, power consumption, and specialized equipment
Solution Approach 1:
The patent applies preliminary action by pre-charging portable chargers to high state-of-charge levels (90-100%) before deployment. These pre-charged portable chargers then serve as activation power sources for multiple battery racks during activation, eliminating the need for external power equipment and reducing activation time significantly
Solution Approach 2:
The patent introduces portable chargers as intermediary devices between the power grid and battery racks during activation. These portable chargers act as mobile power sources that can be transported to remote locations and used to activate multiple battery racks without requiring external power infrastructure or specialized activation equipment
2Reliability
If traditional activation procedures are used for battery systems, then batteries can be activated, but the process is power-intensive and requires specialized equipment
Solution Approach 1:
The patent implements self-service by having fully charged battery racks serve as power sources for activating other battery racks. The activated battery racks then become power sources themselves, creating a self-sustaining activation chain that eliminates external power requirements and reduces overall activation power consumption
Solution Approach 2:
The patent recovers energy by using discharged portable chargers that are replenished by already-activated battery racks. This energy recovery approach allows the same portable charger to be used multiple times for activating different battery racks, reducing total power consumption from the initial power source
3Reliability
If batteries are activated during production, then activation can be completed under controlled conditions, but it creates logistical challenges and increases deployment complexity
Solution Approach 1:
The patent segments the activation process into portable, transportable units (portable chargers) that can be independently deployed. This segmentation allows activation equipment to be divided into manageable modules that can be transported and deployed at remote locations without requiring complex centralized activation infrastructure
Solution Approach 2:
The patent inverts the traditional activation approach by having batteries activate other batteries rather than external equipment activating batteries. This inversion eliminates the need for specialized activation equipment at deployment locations and simplifies logistics by allowing standard battery units to serve as activation sources
