0000 A dynamic multi-phase defined pattern charging (DDPC) system and method for optimizing the charging of rechargeable battery cells and battery systems. The invention applies a predefined, repeatable charge pattern such as square, ramped square, sinusoidal, tangential, sawtooth, or phase-shifted dual-source forms to each charging phase, while dynamically adjusting offset, amplitude, and duty cycle parameters based on real-time feedback from voltage, current, temperature, and impedance measurements. Unlike conventional adaptive charging, which continuously varies current and treats the resulting profile as a shifting waveform, the DDPC approach uses fixed-shape patterns and adjusts only offset, amplitude, and duty cycle. This preserves pattern stability, improves repeatability, and enhances electrochemical predictability. The system supports single-source, dual-source, and multi-source configurations, and can switch patterns during charging to enhance SEI formation, reduce thermal stress, or accelerate completion. Applicable to manufacturing formation lines, in-field optimization, and ultra-fast charging scenarios.
