Lithium cell simulating device

A lithium cell simulating device comprising:

• a programmable power supplying module for converting an external power into a set power to be supplied to a device under test (DUT);
• a lithium cell status controlling module for providing a lithium cell status signal to the DUT;
• a load setting module adapted to set a battery level and a charging mode and electrically connected to the DUT so as to receive the set power via the DUT;
• a control unit electrically connected to the programmable power supplying module, the lithium cell status controlling module, and the load setting module, adapted to allow the programmable power supplying module to provide the set power suitable for use by the DUT, adapted to allow the lithium cell status controlling module to set different statuses of the lithium cell according to preset testing criteria, and adapted to allow the load setting module to set different battery levels and different charging modes according to the preset testing criteria;
• and
• a device under test (DUT) status detecting module electrically connected to the DUT and the control unit to generate a status signal for indicating whether the DUT is ON or not and send the status signal to the control unit.
