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.

Provided is a battery charging system comprising (a) at least one charging circuit to charge at least one rechargeable battery cell; (b) a heat source to provide heat that is transported through a heat spreader element, implemented fully or partially inside said at least one battery cell, to heat up the battery cell to a desired temperature Tc before or during battery charging; and (c) cooling means in thermal contact with the heat spreader element configured to enable transporting internal heat of the battery cell through the heat spreader element to the cooling means when the battery cell is discharged. Charging the battery at Tc enables completion of the battery in less than 15 minutes, typically less than 10 minutes, and more typically less than 5 minutes without adversely impacting the battery structure and performance.

A battery system includes a battery cell, a thermoelectric cooler (TEC) that cools the battery cell, a temperature sensor that detects a temperature of the battery cell, and a battery management unit (BMU) controller. The BMU controller activates the TEC to cool the battery cell in response to determining that a state of charge (SOC) of the battery cell is greater than a threshold SOC and the temperature of the battery cell is greater than a threshold temperature.

A temperature controlled enclosure that includes a temperature control device for controlling the temperature within an internal cavity of the temperature controlled enclosure. The temperature controlled enclosure also includes one or more charging ports for receiving and charging a battery pack. A controller within the temperature controlled enclosure controls the temperature within the internal cavity to a predetermined or desired temperature (e.g., 20° C.). When a battery pack is received in the one or more charging ports, the temperature of the battery pack can be determined. If, for example, the temperature of the battery pack is below 0° C., the battery pack is allowed to warm up inside the temperature controlled enclosure before the battery pack is charged.
