Technical Overview of Inductive Pulse Charging
Understanding the mechanisms, measurements, and methodology behind energy gain systems
Understanding Coefficient of Performance (CoP)
The Coefficient of Performance is the key metric used to measure energy efficiency in these systems.
CoP = Energy Out ÷ Energy In
• CoP = 1.0: Break-even (100% efficiency)
• CoP < 1.0: Energy loss (normal for most systems)
• CoP > 1.0: Energy gain (what Perry achieved!)
Lead-Acid Results
Battery Type: 80Ah AGM
CoP Range: 1.5 to 2.6
Net System CoP: ≈ 1.0 (after losses)
Accounting for 15-30% pulse generator inefficiency
Lithium Iron Phosphate Results
Battery Type: 18Ah LFP
CoP Range: 6 to 12
Net System CoP: 1.2 to 2.4
Even with ≈20% pulse generator efficiency
System Components and Operation
An inductive pulse charging system consists of several key components working together:
1Pulse Generator
Creates rapid on/off switching of current through an inductor coil. This can be achieved through mechanical rotors or solid-state transistor circuits.
2Induction Coil
When current is suddenly interrupted in the coil, it generates a high-voltage "flyback" pulse due to the collapsing magnetic field. This is based on Faraday's law of electromagnetic induction.
3Rectification Circuit
Diodes ensure the high-voltage pulses flow in only one direction toward the battery, preventing reverse current flow.
4Battery Under Charge
The target battery receives the high-voltage pulses, which interact with the battery chemistry in ways that differ from conventional DC charging.
Peak Response Frequency
One of Perry's key discoveries is that each battery has an optimal peak response frequencyat which energy gains are maximized.
Important Finding
Typical Frequency Ranges:
- • Lead-Acid batteries: Often around 1-5 kHz
- • Lithium batteries: Can vary widely, 500 Hz to 10+ kHz
- • Individual variation: Each specific battery may have its unique optimal frequency
How Energy Gains Are Measured
Perry uses rigorous scientific methodology to measure energy gains:
Baseline Measurement
Measure the battery's energy content before pulse charging using controlled discharge testing
Input Energy Measurement
Carefully measure all energy going into the pulse charging system (voltage × current × time)
Pulse Charging Period
Apply inductive pulses to the battery at the optimal frequency for a defined period
Output Energy Measurement
Discharge the battery completely under controlled conditions and measure total energy extracted
Calculate CoP
Compare (Energy Out - Baseline) / Energy In to determine Coefficient of Performance
Additional Benefits of Pulse Charging
Even beyond the energy gains, inductive pulse charging provides several practical benefits:
Sulfation Reversal
High-voltage pulses can break down lead sulfate crystals in lead-acid batteries, restoring capacity to old or damaged batteries
Extended Cycle Life
Batteries charged with pulses can survive more charge/discharge cycles than conventionally charged batteries
Reduced Internal Resistance
Pulse charging can lower a battery's internal resistance, improving its overall performance
Improved Charge Acceptance
Batteries become more receptive to accepting charge, reducing charging time
Theoretical Framework: Extended Electrodynamics
Understanding the "why" behind the energy gains
The energy gains observed challenge conventional closed-system thermodynamics. Researchers propose Extended Electrodynamic Theory (EED) as a framework:
Scalar-Longitudinal Waves
Different from standard transverse electromagnetic waves; these travel along the direction of propagation and may interact with matter differently
Divergent Vector Potentials
Mathematical descriptions of electromagnetic fields that may represent real energy flow not captured by conventional measurements
Environmental Energy Coupling
The system may be "open" in ways we don't fully understand, allowing energy exchange with the local electromagnetic environment or vacuum fluctuations
