Abstract

Selon l'invention, des espaces de ventilation (31, 43) sont formés dans un logement de batterie (5) destiné à recevoir une batterie (21) et dans un logement de chargeur (6) destiné à recevoir un chargeur (34). Le logement de chargeur (6) est placé à l'arrière du logement de batterie (5) et l'extrémité avant du boîtier de chargeur (6) est reliée à l'extrémité arrière du boîtier de batterie (5) de sorte que les espaces de ventilation (31, 43) des deux boîtiers peuvent communiquer l'un avec l'autre. L'extrémité avant du boîtier de batterie (5) comporte un orifice d'aspiration d'air, et un ventilateur électrique (38), servant à envoyer de l'air dans le logement de chargeur (6), est monté à l'extrémité arrière de ce dernier.
