Battery container for use in lithium-ion battery pack to accommodate electrochemical electricity storage cells for e.g. electric car, has groove formed by channel for air flow to maximize pressure and velocity of air with respect to zones

摘要

The container has a groove (13) formed on an external surface, where an opening of the groove is placed such that an air flow (F) enters into the groove. The groove is formed by a channel for flow of the air so as to maximize pressure and velocity of the air with respect to zones (111, 112) of the external surface of the container, which comprises maximum temperature value. The channel comprises barriers (14-17) for separating the penetrating air flow from outgoing air flows (f1, f2). An independent claim is also included for an electric vehicle or a hybrid vehicle.
