Modular Hybrid Energy Storage System for Inventory Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy storage systems for mobile units, such as vehicles and portable devices, require multiple singular units of combined capacitors and batteries to meet various energy demands, leading to inventory challenges and inefficiencies, as existing hybrid systems are manufactured as single products rather than modular components.
Innovation Solution
A modular system comprising separate lithium-ion battery and supercapacitor modules that can be mechanically and electrically connected to form a hybrid energy storage device, allowing for customizable power modules by selecting the appropriate battery and capacitor combination based on application needs, with the capacitor being recharged using a flywheel generator or alternator and the battery being recharged using a portable power pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple singular units of combined capacitors and batteries are manufactured as single products, then various energy demands can be met, but inventory challenges and inefficiencies occur
Solution Approach 1:
The hybrid energy storage system is divided into separate battery module and capacitor module that can be independently manufactured and then combined. This segmentation allows each module to be produced as a standardized component, reducing inventory complexity while maintaining the ability to meet various energy demands through different module combinations.
Solution Approach 2:
The standardized battery module and capacitor module are designed with universal interfaces and specifications that allow them to be combined in multiple configurations. This multi-functionality enables a single set of module types to serve various energy storage applications, eliminating the need for multiple specialized product lines.
2Quantity of substance
If batteries are made larger to hold more power, then charge capacity increases, but recharging time increases to 4-7 hours
Solution Approach 1:
The system merges a battery module and a capacitor module into a hybrid energy storage unit. The capacitor component provides rapid charging capability, allowing the combined system to accept high power charges quickly, while the battery provides sustained energy storage. This combination resolves the trade-off between charge capacity and recharging time.
3Speed
If capacitors are used instead of batteries, then charging speed increases to almost instant, but power storage capacity decreases to small amounts
Solution Approach 1:
The hybrid system combines a capacitor module with a battery module, where the capacitor provides rapid charging capability and the battery provides sustained energy storage. This merging allows the system to achieve both fast charging speed and adequate power storage capacity that neither component could provide alone.

Function Achieved in This Case
This modular approach reduces inventory needs, extends battery life by leveraging the capacitor's cycling efficiency, and allows for efficient power delivery and recharging, enhancing the overall energy storage capabilities and reducing the weight and cost of energy storage systems.
Implementation Method 1
Capacitors use static electricity (or electrostatics) rather than chemistry to store energy. A capacitor utilizes two opposing conducting metal plates with an insulating material there between. The insulating material is referred to as a dielectric.
Implementation Method 2
Batteries utilize two electrical terminals, referred to as 'electrodes.' The electrodes are separated by a chemical substance called an electrolyte. Electrical energy is released in response to a chemical reaction involving the electrodes and the electrolyte.

AI summary
A method of charging a mechanical object using a charge storage device. The method includes determining that an initial battery has lost voltage, removing the initial battery, and installing a replacement battery. Installing the replacement battery places the replacement battery in electrical communication with an adjacent capacitor. In another embodiment, the method includes providing a capacitor in a locomotion machine, and energizing a starter in electrical communication using the capacitor. The method also includes starting an engine of the locomotion machine using a charge from the starter, and then re-charging the capacitor as the locomotion machine moves. The method further comprises determining that the capacitor has lost voltage due to insufficient recharge activity, and re-charging the capacitor with a portable power pack.
