Abstract
A module of elementary electrical energy storage cells includes a first set of elementary cells that are interconnected so as to supply a first voltage in a first voltage range and a second set of elementary cells that are interconnected so as to supply a second voltage in a second voltage range. At least one elementary cell from the second set is arranged between two elementary cells from the first set.
Claims13
A module of elementary electrical energy storage cells, the module comprising:
- a first set of elementary cells that are interconnected, each elementary cell of the first set of elementary cells supplying a first voltage in a first voltage range;
- a second set of elementary cells that are interconnected, each elementary cell of the second set of elementary cells supplying a second voltage in a second voltage range, at least one elementary cell from the second set being, arranged between two elementary cells from the first set, and the first voltage being higher than the second voltage;
- connection elements from a first group of connection elements that are located on a first portion of the module and are configured to electrically link positive and negative electrical contacts of the first set of elementary cells to one another so as to supply the first voltage;
- connection elements from a second and from a third group of connection elements that are located on a second portion of the module and are configured to electrically link positive and negative electrical contacts of the second set of elementary cells to one another so as to supply the second voltage;
- and
- an electrical linking element located on a third portion of the module and configured to connect a first electrical circuit formed of the first set of elementary cells and of the connection elements from the first group to a second electrical circuit formed of the second set of elementary cells and of the connection elements from the second and third groups, wherein
- the connection elements of the first group of connecting elements, the connection elements of the second and third groups of connecting elements, and the electrical linking element are located on different sides of the module, and the connection elements of the first group of connecting elements and the connection elements of the second and third groups of connecting elements are located on opposite sides of the module.
