Dynamic Boost Battery Charger Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard battery charging methods are not adaptive and often result in under-charging or over-charging due to fixed initiation and reversion thresholds, which do not account for battery variations, temperature, and depth of discharge, leading to inefficient and potentially damaging charging cycles.
Innovation Solution
A dynamic boost charging method that uses a battery charger control system to selectively produce charging currents from preset DC voltage settings, monitoring the output current and adjusting the voltage settings based on measured data to determine the appropriate time for completing the recharge cycle, thereby adapting to the battery's condition and environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed initiation and reversion thresholds are used in standard demand-based boost charging, then the charging system is simple to implement, but the battery may be under-charged or over-charged due to lack of adaptability to battery variations, temperature, and depth of discharge
Solution Approach 1:
The patent implements dynamic threshold adjustment where initiation and reversion thresholds are no longer fixed values but adapt dynamically based on real-time battery conditions including state of charge, temperature, and depth of discharge. The charging control system continuously monitors battery parameters and adjusts thresholds accordingly, transforming the static charging control into a dynamic adaptive system that optimizes charging for each specific battery condition
Solution Approach 2:
The patent changes the charging parameters (voltage and current thresholds) based on measured battery conditions. Instead of using fixed initiation and reversion thresholds, the system modifies these parameters dynamically according to battery state of charge, temperature, and discharge depth, allowing the charging behavior to adapt to varying battery characteristics and environmental conditions
2Manufacturing precision
If fixed time extension is added to boost charge to achieve more complete charge, then under-charging is reduced for deeply discharged batteries, but over-charging occurs for lightly discharged batteries
Solution Approach 1:
The patent dynamically adjusts the boost charge duration and termination parameters based on real-time battery conditions. Instead of applying a fixed time extension to all batteries, the system modifies charging parameters including duration, voltage, and current thresholds according to the specific battery's state of charge, capacity, and temperature, preventing both under-charging and over-charging
Solution Approach 2:
The patent implements continuous feedback monitoring of battery parameters during charging. The system measures battery voltage, current, and temperature in real-time and uses this feedback to dynamically adjust charging parameters and determine optimal termination points, replacing fixed time-based control with adaptive feedback-driven control that prevents over-charging while ensuring complete charge when needed
3Reliability
If conservative reversion transition current settings are used, then over-charging is avoided, but under-charging occurs due to premature termination of boost charge
Solution Approach 1:
The patent dynamically adjusts the reversion transition current threshold based on battery conditions rather than using a conservative fixed value. The system modifies this parameter according to state of charge, temperature, and battery age, allowing higher current thresholds when appropriate to maintain reliability while improving charging efficiency and reducing premature termination

AI summary
There is disclosed a dynamic boost charging system having a monitoring component configured to measure total DC current and/or battery current and a reporting component configured to transmit output data of the total DC current and/or battery current measured. A battery charger control system in operable connection with the monitoring component receives the data of the total DC current and/or battery current measured by the monitoring component, and is configured to: obtain an initial time and/or charge measurement; determine a time and/or charge to complete a recharge cycle based on the time and/or charge measurement; selectively use at least two preset DC output voltage settings, one of the at least two preset DC voltage settings being a float voltage, and another of the at least two preset DC voltage settings being a boost voltage; and maintain the boost voltage until the time has passed the charge has been provided.
