A warming tray includes an upper plate, on which food or a dish containing the food can be placed, and which is adapted to be coupled with a lower plate that includes an upper side adapted to accommodate the upper plate and a lower plate, the upper and lower sides being joined by a perimeter wall. The lower plate includes one or more heating resistances, a thermostat, one or more electric energy accumulators, a charge regulator, a discharge regulator, an on/off switch, and a recharge connector. Turning the switch on or off supplies power to the thermostat and to the heating resistances, which provide for heating the upper side of the lower plate and the upper plate. 1. A warming tray comprising:at least one upper plate (V), adapted to receive food or a dish containing the food to be heated, and to be coupled with a lower plate (P),{'b': 1', '1', '2', '3, 'i': a', 'b, 'wherein said lower plate (P) comprises an upper side (P, P) adapted to accommodate said upper plate (V) and a lower side (P), said upper and lower sides being joined by a perimeter wall (P),'} [{'b': 1', '1, 'i': a', 'b, 'at least one heating resistance (R) fixed to or in contact with said upper side (P, P);'}, {'b': 1', '1, 'i': a', 'b, 'at least one thermostat (T) electrically connected to said heating resistance (R) and placed in contact with said upper side (P, P);'}, 'at least one accumulator of electric energy (A);', 'at least one recharge connector (Y) directly or indirectly connected to said accumulator of electric energy (A);', 'at least one on/off switch (O) interposed between said thermostat (T) and said accumulator of electric energy (A),, 'wherein said lower plate (P) is adapted to housewherein operation of said on/off switch (O) provides power to said heating resistance (R) through said thermostat (T), andwherein said thermostat (T) interrupts power supply to said heating resistance (T) when a temperature set on the thermostat (T) has been reached.2. The warming tray according to claim 1 ...
