Supply device and modular supply system so obtained

A modular supply system to supply an electric, or hybrid, vehicle, comprising:

• a battery housing including a plurality of housing seats having a substantially prismatic shape, each housing seat being provided with a first connector comprising a respective plurality of electrical contacts;
• a plurality of supply devices provided with tubular bodies having a substantially prismatic shape and configured to contain a respective battery pack formed by a plurality of cells organized in a predetermined number of superimposed layers, each supply device of said plurality:
• being arranged to move from a position external to said battery housing, to an internal position, which is arranged to engage into a respective housing seat of said battery housing;
• being provided with a second connector including a plurality of electrical contacts and arranged to be connected to said first connector including said respective plurality of electrical contacts when said supply device is positioned in said internal position, to supply a predetermined electric power, and
• being provided with a respective control unit configured to monitor a state of functioning and to manage a charge of the respective battery pack;
• and
• a central control unit configured to monitor the state of functioning and to manage the charge of the different supply devices;
• wherein:
• each layer of cells includes a first group of cells and a second group of cells;
• between said first group of cells and said second group of cells a housing channel is formed arranged to contain, in use, a plurality of connection cables arranged to connect said battery pack with said second connector and, therefore, to said first connector;
• said housing channel is delimited by a first lateral containment wall and a second lateral containment wall in such a way to separate said plurality of cells from said housing channel;
• said battery pack comprises a plurality of superimposed layers of cells;
• between two consecutive layers of said plurality of superimposed layers an interposition member is provided including an electrical connection member provided with a first plurality of contacting portions at a first side and a second plurality of contacting portions at a second side at respective axial symmetric positions with respect to an axis of symmetry,
• a cell of a first layer of the superimposed layers is positioned, in use, adjacent to a respective contacting portion of said first plurality of contacting portions,
• a cell of a second layer of the superimposed layers is positioned, in use, adjacent to a respective contacting portion of said second plurality of contacting portions;
• said electrical connection member is provided with a plurality of protruding portions at the first side and at the second side at which said first plurality of contacting portions and said second plurality of contacting portions are provided, respectively;
• said electrical connection member is made of a metallic material;
• said electrical connection member comprises a first plate portion and a second plate portion arranged on substantially parallel planes and provided respectively with the first plurality of contacting portions and the second plurality of contacting portions aligned with each other, and
• said first plate portion and said second plate portion are connected to each other by a connection portion configured in such a way to allow said first plate portion and second plate portion to elastically approach, or depart, with respect to one another.
