Solution Overview
Problem
Existing battery charging systems face issues with unwanted side effects such as incomplete charging, prolonged charging times, and safety hazards due to pulsation devices that emit confusing signals and cause excess hydrogen gas production, leading to potential short circuits from accumulated deposits like lead sulfate.
Innovation Solution
A battery charging and pulsating system that includes a charger with a controller and a pulsator connected to the battery terminals, featuring a filter to attenuate signals, voltage and current measurement circuits to synchronize pulsation with charging cycles, and a capacitor with a switching device to prevent interaction with the charger when the battery is removed, ensuring safe and efficient pulsation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pulsator is connected to the battery terminals to break down accumulated deposits, then the battery operation is improved, but unwanted signals are emitted that confuse the charger and result in incomplete charging
Solution Approach 1:
The system is divided into separate functional modules: a pulsator module for deposit removal and a charger module for charging, with each having its own controller. The pulsator controller and charger controller operate independently, allowing the pulsator to function without interfering with the charger's ability to detect charging status through voltage measurements.
2Reliability
If a pulsator is connected to the battery terminals to break down accumulated deposits, then the battery operation is improved, but the battery charger runs much longer than necessary producing excess hydrogen gas and creating safety hazards
Solution Approach 1:
The charger controller continuously monitors battery voltage to determine charging status. When the voltage reaches a predetermined threshold indicating full charge, the charger controller automatically terminates the charging process. This feedback mechanism prevents overcharging and the associated hydrogen gas production, while the pulsator controller independently manages deposit removal.
3Device complexity
If the pulsator and charger share common control circuits, then device complexity is reduced, but the pulsator interferes with the charger's voltage measurements
Solution Approach 1:
The control system is segmented into separate controllers: a pulsator controller and a charger controller. Each controller has its own measurement and control circuits, eliminating interference between the pulsator's high-voltage pulses and the charger's precise voltage measurements. This segmentation ensures measurement precision while maintaining manageable device complexity through modular design.
4Reliability
If the pulsator is activated continuously to prevent deposit accumulation, then battery reliability is improved, but energy consumption increases and safety hazards arise
Solution Approach 1:
The pulsator is activated periodically rather than continuously. The pulsator controller monitors battery voltage and activates the pulsator only during specific conditions: when voltage is at or below a predetermined threshold and/or at or above a predetermined gassing voltage, and only when the charger controller indicates the charger is inactive. This periodic activation maintains deposit breakdown effectiveness while significantly reducing energy consumption and safety hazards.

Implementation Method 6
pulsation devices have been developed to counteract the accumulation of such deposits by applying pulsation energy, such as radio frequency energy, to the battery. Without being limited to any particular theory, it is believed that pulsation energy breaks down the accumulated deposits and facilitates free electron flow between the battery plates
