Provided is a battery system including a battery management module, a battery module, and a controller. The battery management module includes a main switch between an external terminal and a battery terminal, and a heating switch between the external terminal and a heating terminal. The battery module includes a cell, a heating element, and a control switch connected to the heating element. The controller is configured to detect a connection with a charger, detect a temperature of the cell, when the temperature is lower than a first value, turn off the main switch and turn on the heating switch and the control switch to supply heating power from the charger to the heating element, and when the temperature becomes higher than a second value by the heating element, turn off the heating switch and turn on the main switch to supply charging power from the charger to the cell.

Battery system with heating element and method of controlling the same

The described technology relates to a battery pack and a data transmission method for the battery pack. In one embodiment, the battery pack includes a battery comprising at least one battery cell and a controller configured to check a state of the battery and generate a battery state signal corresponding to the state of the battery. The battery pack also includes a switch circuit configured to operate based on the battery state signal and a resistor circuit configured to be electrically connected to a reference node through the switch circuit. The switch circuit is configured to make or break electrical connection between the resistor circuit and the reference node based on the battery state signal.
