▎ 摘　　要

NOVELTY - The system has a charging circuit for charging a rechargeable battery cell. A heat source provides heat that is transported through a heat spreader element (14) to heat up a battery cell to a desired temperature before or during charging of the battery cell. A cooling unit in thermal contact with the heat spreader element is configured to transport internal heat of the battery cell through the heat spreader element to the cooling unit when the battery cell is discharged, where electrolyte is filled between between an anode (16) and a cathode (20). The heat spreader element is inclined partially or entirely inside a protective housing (12). The battery cell comprises a temperature sensor for measuring an internal temperature of the battery and sending a signal of internal temperature to the charging circuit. The cooling unit is selected from a heat sink (23), a heat pipe, a vapor chamber, a stream of flowing fluid, a thermoelectric device, a heat exchanger and a radiator. USE - Battery rapid charging and cooling system. ADVANTAGE - The system encapsulates cathode active material particles with graphene so as to enable faster heating of the battery to a desired temperature for fast charging if coupled with a high thermal conductivity heat spreader, avoids overheating danger when the electric current is switched on, allows a large amount of current to reach location in an extremely short period of time and reduces charging time of a rechargeable battery without negatively impacting the battery. The system makes the chargeable battery to operate in a safe mode with reduced or eliminated chance of overheating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a battery rapid charging and cooling system operating method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a battery rapid charging and cooling system.
