Abstract: An electric battery includes a plurality of electric energy generators and a system for mechanical and thermal conditioning of the elements, which system includes a one-piece structural body in which housings are formed in order to each receive an element, in which the housings have at least one internal area of contact with an element, and the contact area is continuous and has a shape suitable for ensuring contact between the area and the periphery of the element, in which the body also includes chambers that each extend around a contact area, and which system also includes a device enabling a thermal conditioning fluid to circulate in the chambers so as to ensure the thermal conditioning of the elements.

Abstract: A method of monitoring the voltage UELT of an electrical energy generating element of a battery, comprising measuring the voltage UBRUT at the terminals of said element by means of a subtractor assembly and carrying out a calibrating procedure. The invention also relates to a monitoring device for the implementation of this method, a system for monitoring voltages of elements of a battery as well as an electric battery comprising at least one module formed from several electrical energy generating elements, said battery comprising, for each module, a system for monitoring voltages.

Abstract: An electric battery has a plurality of elements generating electrical energy. A system for the mechanical and thermal packaging of the elements includes a bed of thermal packaging fluid on which the elements are placed so as to leave a lateral space between the adjacent elements. The packaging system further includes a plurality of thermal packaging modules, each provided with a path for the fluid to flow between an upstream port and a downstream port, each flow path extending along a lateral space with the ports in fluid communication with the bed. The packaging system further includes a structural matrix made of a thermally conductive and electrically insulating polymer resin, the matrix filling the lateral spaces, at least partly encapsulating the generator elements and the packaging modules.
