Problems solved by technology

[0006] These hybrid power supplies thus allow limiting the necessary power of the primary energy storage source as well as limiting the total amount of power supplied
However, for a given power supply, it is not always appropriate to favor a complex multi-source architecture over a simple solution utilizing a single source such as a battery
Therefore, there is a risk in developing new power supply architectures based on hybrid power supplies that may prove to be bulkier and less efficient than previous architectures

Embodiment Construction

[0022] figure 1 A power supply architecture 10 for a load 11 is shown. The power Pchg(t) required by the load 11 over time is accomplished by the two energy storage sources 13 , 14 . The first energy storage source 13 corresponds to a battery bank delivering power Pbat(t), while the second energy storage source 14 corresponds to a supercapacitor bank delivering power Psc(t). As a variant, changes may be made to these energy storage sources without altering the invention. The load 11 corresponds to any actuator such as a servo-controlled jack.

[0023] The architecture 10 through figure 2 to be optimized using the optimization method described in . In a first step, the method determines a duty profile 16 in step 20 , the data of which depend on the power Pchg(t) required by the load 11 over time t. An example of such a task profile 16 is at image 3 shown in . In practice, such a task profile 16 is determined by carrying out sets of tests for the power Pchg(t) required ...

Abstract

The invention relates to a method for optimising the architecture of the power supply of a load, comprising the following steps: determination of a mission profile (16) sizing according to the power required by the load over time; definition of the sources of energy storage for hybridisation; association of a characteristic behaviour model with each source of energy storage; determination of the couples of sources of energy storage that can generate the mission profile with a minimum mass; and determination, from the potential couples of sources of energy storage, of the couple with the weakest mass.

Description

technical field [0001] The invention relates to a method for optimizing the power supply architecture of a load. More specifically, the present invention relates to power supplies comprising a plurality of energy storage sources, also termed "hybrid power supplies". [0002] A "hybrid power supply" is understood to be a power supply comprising multiple sources of energy storage, such as batteries associated with a bank of ultracapacitors or batteries associated with fuel cells. [0003] The invention has applications in many fields and can be used in aircraft, satellites or spacecraft. Background technique [0004] There are several known devices for powering loads using a hybrid power supply. These devices are found in particular in electric buses and trams, or in electric or hybrid vehicles. These devices employ complementary energy storage sources, such as batteries and supercapacitor banks. The prior art includes, inter alia, Patent No. FR2947006, which describes a d...
