Abstract

An electric energy management system with thermoelectric power supply conversion function includes a controller, multiple first battery modules, a second battery module and a connection switching module. Each first battery module includes a first battery and a thermoelectric unit. The multiple first battery modules and the second battery module supply power to high-voltage equipment and low-voltage equipment, respectively. Connection ends of the multiple thermoelectric units are connected to the connection switching module. When the first batteries are discharging, the controller controls the connection switching module to make the thermoelectric units connected in series between the two series connection ends for supplying electric energy to the second connection end of the second battery module. The thermoelectric unit converts the thermal energy generated by the first battery and provides it to the low-voltage device, thereby reducing the electrical energy that the second battery module outputs and improving energy utilization efficiency.
