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 rechargeable battery pack including: a cell holder configured to accommodate unit battery cells; a lower case configured to accommodate the cell holder; an upper case attached to an opening of the lower case and covering the cell holder and the unit battery cells; a tab having an end portion drawn out of a through-hole of the upper case to be on an outer surface of the upper case while coupling the unit battery cells; and a terminal electrically coupled to the end portion of the tab while overlapping therewith and attached to the upper case while covering the through-hole.

Rechargeable battery pack

A battery pack including a plurality of battery arrays, each battery array including unit batteries that each have a terminal, the plurality of battery arrays being stacked in a first direction; an insulator on at least one side of the battery arrays, terminals of the unit batteries being on the one side; and a sensing bar on the insulator, wherein the insulator includes at least one opening therein, at least one terminal being exposed through the at least one opening, and the sensing bar is electrically connected to the at least one terminal exposed through the at least one opening to sense a state of the battery array.

A battery array includes: a plurality of batteries arranged into 2N+1 bundles, each of the bundles including M+1 batteries of the batteries arranged in parallel (where N and M are natural numbers); a plurality of connection tabs arranged at a first end of the battery array and at a second end of the battery array, each of the connection tabs being coupled to a corresponding pair of the bundles to electrically couple a first bundle through a 2N+1th bundle of the bundles in series; a first output terminal having a first polarity, and electrically coupled to the first bundle; and a second output terminal having a second polarity, and electrically coupled to the 2N+1th bundle, the second output terminal being adjacent to the first bundle.

Battery array and battery pack having the same

A battery pack frame for accommodating a plurality of secondary cells arranged in parallel with each other, each secondary cell extending axially in a first direction, the battery pack frame including an upper frame for coupling with an upper portion of each of the plurality of secondary cells so as to accommodate the plurality of secondary cells; a lower frame facing the upper frame, the lower frame being for coupling with a lower portion of each of the plurality of secondary cells, the upper and lower frames being spaced from each other in the first direction; and a plurality of elastic members disposed in parallel with each other and extending in the first direction.
