▎ 摘　　要

NOVELTY - Battery charging system comprises at least one charging circuit to charge at least one rechargeable battery cell and a heat source to provide heat that is transported through a heat spreader element (14), implemented fully or partially inside at least one battery cell, to heat up battery cell to a desired temperature (Tc) before or during charging of battery cell. USE - Battery charging system. ADVANTAGE - The battery charging system avoids the danger of damaging the battery due to battery charging at low ambient temperatures and reduces the charging time, and heats the rechargeable batteries to a near room-temperature range or higher suitable for fast charging. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of operating a battery charging system comprising multiple charging stations, which involves: (A) positioning multiple rechargeable battery cells respectively in multiple charging stations; (B) operating at least a heat source in battery charging system to provide heat that is transported through a heat spreader element, implementing fully or partially inside each of battery cells, to heat up battery cells to a desired temperature (Tc); and (C) activating at least one charging circuit in battery charging system to charge battery cells at or near (Tc) until battery cells reach a desired degree of charge. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of battery charging system.
