Abstract: A battery pack is provided. The battery pack includes first and second temperature sensors that are disposed in first and second interior spaces, respectively. The first temperature sensor generates a first signal indicative of a first temperature level of the battery cell. The second temperature sensor generates a second signal indicative of a second temperature level of the DC-DC voltage converter. The battery pack further includes a microprocessor that determines a first fan speed percentage value of the electric fan based on the first temperature level, and a second fan speed percentage value of the electric fan based on the second temperature level. The microprocessor selects the first fan speed percentage value if the first fan speed percentage value is greater than the second fan speed percentage value.

Abstract: A battery pack having a battery module, a thermoelectric heat pump, and a cooling manifold is provided. The battery module has a first battery cell, a housing, and a first solid cooling fin. A first panel portion of the first solid cooling fin is disposed against the first battery cell. A second panel portion of the first solid cooling fin is disposed on an outer surface of the housing and is coupled to an end portion of the first panel portion. A first side of the thermoelectric heat pump is disposed against the second panel portion, and a second side of the thermoelectric heat pump is disposed against the cooling manifold. The thermoelectric heat pump transfers heat energy from the first solid cooling fin to the cooling manifold in response to a first electrical current flowing through the thermoelectric heat pump in a first direction, to reduce a temperature level of the first battery cell.
