A pulsed discharge system with an intermitting partial charge for improved battery efficiency

Drone enabled autonomous charging-on-demand

“…Pulse charging, however, has its drawbacks, including electrode cracking and pulverization, decrease in power density, high cost due to the expensive current sensors needed for controlling the duty cycle of the charge pulse, and increased heat generation in parallel cells due to balancing events between pulses [49,56,62]. Proposed strategies aimed at resolving these issues include a duty-varied voltage strategy for pulse chargers, adding a partial charge phase to the discharge profile, and dynamic pulse modulation during charging [63][64][65].…”
