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

A battery pack having at least one cell module that is connected between a plurality of pack terminals, the battery pack including: at least one thermoelectric element disposed at each of the at least one cell modules; a thermoelectric element power supply circuit configured to supply a driving voltage to the at least one thermoelectric element; and a controller configured to control the thermoelectric element power supply circuit to transfer a first voltage that is supplied for driving the thermoelectric element from a charger as the driving voltage for the at least one thermoelectric element when a temperature of the at least one cell module is out of a first range in a charging mode, the first voltage being different from a second voltage that is a charging voltage supplied to the battery pack from the charger.

Battery pack

A battery module, a vehicle, and a method of manufacturing a battery module, the battery module including a housing accommodating a plurality of secondary batteries; and a thermoelectric element assembly on the housing and in contact with the plurality of secondary batteries through at least one contact opening in the housing, the thermoelectric element assembly being configured to heat or cool the plurality of secondary batteries.

Battery module and vehicle including the same

Battery pack and control method thereof

A battery pack includes a protection circuit module for a plurality of battery cells arranged in parallel in a case. The protection circuit module includes a temperature sensor. An insertion area is at a location of the case corresponding to the temperature sensor and includes a removed part of the case. The temperature sensor extends through the insertion area to contact an outer surface of at least one of the battery cells.
