Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional battery charging methods for generator-based systems can be inefficient and may damage battery modules due to overlooked environmental or electrical conditions, especially when mixed battery types are present, leading to increased costs, weight, and system complexity.
Innovation Solution
A generator-based battery charging system that includes a controller with a processor and memory to analyze sensor signals from a smart sensor, calculating a generator current value and generating a control signal to provide a charging current tailored to the battery module's conditions, allowing for efficient charging without a separate battery charger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional one-step or two-step charging methods are used, then the charging process is simple, but the battery may be damaged due to overlooked environmental or electrical conditions
Solution Approach 1:
The charging system dynamically adjusts charging parameters (current, voltage, temperature compensation) in real-time based on sensor feedback from the battery module, transitioning from static traditional charging to adaptive dynamic charging that responds to changing battery conditions
Solution Approach 2:
The system implements a feedback mechanism where sensors continuously monitor battery voltage, current, and temperature, and the controller uses this feedback information to adjust charging parameters, ensuring safe and efficient charging while preventing battery damage
2Reliability
If a specialized battery charger is used for mixed battery types, then charging accuracy is improved, but system complexity, weight, and costs increase
Solution Approach 1:
The generator-based charging system is designed to universally charge different battery types (lead-acid, lithium-ion, nickel-cadmium, nickel-metal hydride) using a single multi-functional controller that automatically identifies battery type and applies appropriate charging algorithms, eliminating the need for multiple specialized chargers
Solution Approach 2:
The system changes charging parameters (current profile, voltage limits, temperature thresholds) based on detected battery type and conditions, using variable parameter control to adapt to different battery chemistries rather than requiring dedicated hardware for each type
3Weight of stationary object
If generator-based charging is used, then system weight and cost are reduced, but charging efficiency decreases due to inability to adapt to battery conditions
Solution Approach 1:
The battery module provides self-service information through integrated sensors that automatically report their own voltage, current, and temperature conditions to the generator controller, enabling the lighter generator system to achieve efficient charging through the battery's own diagnostic capabilities

AI summary
A system for generator-based charging of a battery module may include the battery module, a sensor located adjacent the battery module, a generator controller comprising a processor and a non-transitory memory device storing instructions. The instructions, when executed by the processor, cause the generator controller to analyze one or more sensor signals received from the sensor. The sensor signals may correspond to a condition of the battery module. The generator controller may then calculate, based on the one or more sensor signals, a generator current value for use in charging the battery module. Next, the generator controller may generate a control signal comprising a command that may cause the generator to provide a charging current having the current value.
