Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage systems cannot simultaneously charge and discharge batteries, limiting their performance, especially when used with renewable sources, and require a central controller to manage charging and discharging cycles.
Innovation Solution
A battery system that quickly switches between series and parallel configurations, controlled by a logic chip, allowing for simultaneous charging and discharging by adjusting the phase frequency and time spent in each configuration, enabling the system to output an average of both series and parallel outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If batteries are connected in series, then voltage output is increased, but amperage output remains limited to individual battery capacity
Solution Approach 1:
The system dynamically switches between series and parallel connections based on operational requirements. During discharge, batteries are connected in series to provide high voltage. During charging, batteries are connected in parallel to accept high current. This dynamic reconfiguration allows the system to optimize for either voltage or amperage depending on the operational phase, resolving the contradiction between voltage output and amperage output.
Solution Approach 2:
The system employs periodic switching between series and parallel configurations at high frequency (e.g., 1000 times per second). This periodic action allows the system to alternately achieve high voltage (series) and high amperage (parallel) states, effectively providing both characteristics over time and resolving the contradiction between limited voltage and amperage in static configurations.
2Extent of automation
If a central controller is used to manage charging and discharging, then system control is achieved, but system complexity increases
Solution Approach 1:
The system uses decentralized control where each battery module contains its own logic chip that autonomously manages charging and discharging decisions. The modules self-organize into series or parallel configurations based on their charge states and operational requirements, eliminating the need for a complex central controller. This self-service approach achieves automated control while significantly reducing system complexity.
Solution Approach 2:
The battery system is divided into independent modules, each with its own control logic. This segmentation allows each module to make autonomous decisions about its charging and discharging behavior, distributing the control function across multiple simple units rather than requiring one complex central controller. The segmented architecture reduces overall system complexity while maintaining automated control capabilities.
3Device complexity
If batteries charge and discharge sequentially, then battery management is simplified, but system productivity decreases
Solution Approach 1:
The system dynamically reconfigures battery connections in real-time, switching between series and parallel configurations at high frequency. This allows different battery modules to simultaneously charge and discharge by being in different configurations at different moments. The dynamic switching enables parallel charging and discharging operations, significantly improving productivity while maintaining manageable complexity through automated control logic.
Solution Approach 2:
The system employs rapid periodic switching between charging and discharging phases for different battery modules. By cycling through configurations at high frequency, the system effectively performs simultaneous charging and discharging operations across the battery array. This periodic action increases overall energy throughput and productivity while the control logic manages the complexity of coordinating these operations.

AI summary
A battery system and method may be shown and described. Two or more batteries may be connected in an identical configuration to an output device. The batteries may be controlled by a control unit or logic chip which may be configured to operate in two phases. In the first phase, the two or more batteries may be connected in series. In the second phase, the two or more batteries may be connected in parallel. Switches may be connected to the positive and negative terminals of the batteries to switch the configuration from series to parallel, and vice-versa. A control unit may switch between the two phases at any desirable frequency to produce a desired output voltage and amperage. The switching speed between the two phases may be any number of rotations per second.
