Abstract

A battery pack (1) comprises a plurality of battery cells (2) arranged within a container configured to define one or more passages for a forced flow of temperature-regulating air that maintains the battery cells (2) within a predetermined temperature range. The cells (2) of the battery pack (1) are divided into a plurality of separate blocks (5), each provided with a respective container (5A) isolated from the containers (5A) of the other blocks (5). In the container (5A) of each block (5) is arranged at least one group (3) of battery cells (2). Most, or all, of the temperature-regulating air flow is supplied cyclically only to one of the blocks (5) of battery cells, for a determined time, while the other blocks (5) of cells receive a relatively reduced or null flow of temperature-regulating air, such that, at the end of each cycle, all the blocks (5) of battery cells have received in turn, for a determined time interval, a major flow of temperature-regulating air. In this way it is possible to obtain a much higher heat exchange efficiency compared to the case where the flow rate of the temperature-regulating air were constantly distributed equally among the different blocks of cells. During a warm-up phase, after a cold activation of the battery pack (1), the air flow is supplied in turn only to the blocks (5) of a part of the battery pack (1), so as to make the heating of this part of the battery pack (1) faster. During a charging phase of the battery pack (1), the charging electric current can be supplied only to the block (5) of the battery pack (1) that in turn receives the major air flow, so as to make the cooling more effective where it is most necessary.
