Embodiment Construction

[0040] The invention is particularly intended to propose a rechargeable battery B1 comprising a storage unit suitable for storing electrical energy, at least two main outputs SPk suitable for outputting different types of voltages for supplying different electrical devices of the system V, and for Two charging inputs ER1 and ER2 for DC and AC.

[0041] In the following, it is considered, as a non-limiting example, that the rechargeable battery B1 is part of a motor vehicle of the all-electric type, such as an automobile. But the invention is not limited to this type of system. In fact, the invention relates to all types of systems comprising at least one rechargeable battery, including battery packs, and in particular to land, sea (or river) or air vehicles, installations possibly of industrial type, and buildings. It should also be noted that when the system is a vehicle, its powertrain (or GMP) can be of the all-electric type or of the hybrid (thermal / electric) type.

Abstract

A battery (B1) comprises: storage cells; main outputs (SP1-SP3) delivering different voltages and supplying power to various items of electrical equipment; inputs (ER1, ER2) for charging with single-phase AC or DC current and three-phase AC current; switching means (MI1-MI3) capable of being placed in closed and open states according to instructions and installed on the first (ER1) and second (ER2) inputs and one of the main outputs (SP2); conversion modules, each installed at the output of a group of cells and capable of connecting one of its outputs to the input of another group or to one ofthe main outputs (SP1-SP3) or to one of the inputs (ER1, ER2) according to an instruction; and main control means (MCP) generating each instruction according to the voltage required to supply power to at least one item of equipment or to charge at least one group.

Description

technical field [0001] The present invention relates to rechargeable batteries comprising groups of electrical energy storage units for storing electrical energy and intended to be equipped with certain systems. Background technique [0002] Some systems include at least one rechargeable battery that includes a housing housing a battery cell pack responsible for storing electrical energy. This is the case, for example, in certain vehicles of the all-electric or hybrid type and optionally of the motor vehicle type, and in these vehicles one or more rechargeable batteries are usually mounted on the bottom. [0003] The aforementioned battery cell may be, for example, a lithium ion, Ni-MH, lead, lithium metal polymer (or LMP), or sodium ion type battery. [0004] As an example, in an all-electric or hybrid vehicle, a rechargeable battery may be responsible for supplying different types of electrical equipment (or components) with different types of voltages on different Priva...
