Solicitante:

ALOBAIDI MOHAMMED [US]
CINAGROSSI NICOLA [CH]
SCHUMANN JOCHEN [CH]

Resumen de: WO2022203657A1

Disclosed herein are different charging stations, systems, and methods for recharging swappable or non-swappable batteries having differing states of health, impedance, age, etc. Swappable and non-swappable battery packs may be charged in parallel, but the amount of charge current supplied to each parallel battery pack is determined individually by the battery pack itself. Each battery may have its own maximum charge and/or discharge current limits set individually to avoid using a battery pack over its rating, provide voltage equalization, and control energy flow among the plurality of rechargeable battery packs. This also extends the operating lifetime of older battery packs. In a charging mode, a battery charger may set a floating voltage and each battery pack may take its own current to provide voltage equalization. Additionally, a battery pack can boost its own voltage to maintain the required voltage level by a particular load/application.
