Engineering Contradiction Analysis
1Productivity
If the battery is charged with high current to increase charging speed, then productivity is improved, but the battery deteriorates faster and safety problems occur
Solution Approach 1:
The patent implements dynamic adjustment of charging parameters based on real-time battery state monitoring. The controller continuously monitors voltage, temperature, and charging cycle count, then dynamically adjusts the charging current and voltage thresholds accordingly. This allows the system to achieve fast charging when conditions permit while preventing deterioration when the battery is in vulnerable states.
Solution Approach 2:
The patent changes operating parameters (voltage threshold, current magnitude) based on the battery's state. Specifically, the voltage threshold for charging completion is adjusted according to the charging cycle count and real-time voltage measurements. This parameter adaptation allows the system to optimize charging speed while preventing overcharging and thermal runaway.
2Use of energy by moving object
If the battery is charged to higher voltage to increase energy capacity, then use of energy is improved, but the battery swells and safety problems occur
Solution Approach 1:
The patent employs feedback control by continuously monitoring the battery voltage during charging and comparing it against dynamically adjusted thresholds. The controller uses this feedback to determine when to reduce or stop charging current, preventing the battery from reaching voltage levels that would cause swelling. The feedback loop also monitors temperature to prevent thermal runaway.
Solution Approach 2:
The patent performs preliminary adjustments to charging parameters based on predicted battery state. By monitoring the charging cycle count and estimating the battery's current health state, the system proactively adjusts voltage thresholds and current limits before the battery enters a vulnerable state, preventing swelling before it occurs.
3Productivity
If the battery is charged repeatedly to maintain energy supply, then productivity is improved, but the battery deteriorates and life decreases
Solution Approach 1:
The patent implements a self-adjusting charging system that automatically modifies charging parameters based on the battery's own state indicators (voltage, temperature, cycle count). The controller uses the battery's intrinsic feedback signals to self-regulate the charging process, optimizing the balance between maintaining energy supply and preserving battery life without external intervention.
