Abstract: The present invention relates to an energy accumulation basket, formed by holders provided with multiple housings where there are arranged capacitors held by their ends between holders, the inner walls of the housings having indentations where respective accessory elastic projections are housed, whereby capacitors arranged in the housings fit within the perimeter, and where conformations are defined on the outer face of each holder, said conformations protruding into the housings for supporting the end of the corresponding capacitor, the capacitors being axially retained in the respective housings by means of the conformations of the holders.

Abstract: Power storage module for railway vehicles, comprising multiple interconnected capacitors (1) with terminals (2) for establishing an electrical connection with a single connection plate (7) common to all the capacitors (1) and mechanical securing by means of a support plate (6) placed between the terminals (2) and the connection plane (7), the terminals (2) being oversized in such a way as to define a cooling channel between the support plate (6) and the capacitors (1), the connection plate (7) being insulated from said cooling channel by means of the support plate (6).
