But they are integrated and programmed mainly to produce electricity currently up to 80 Wh / km in peri-urban areas during deceleration, braking, and under-revving phases. However, it is possible to foresee that these components can also be programmed to convert electrical energy into mechanical energy and in this way provide a light hybridization of the vehicle thus equipped (Retrofit-Light concept).

[0036] The electric machine can, for example, operate only in generator mode, but it is also possible to plan to produce this electric machine in the form of an alternator-starter operating in bidirectional mode, for example of the iBSG type under 48V.

[0037] Electrical energy can be stored in DomiBATT© type communicating battery packs, which may or may not be transportable. Depending on the option chosen, the electricity is then available for use from a vehicle, home, or workplace via a dedicated discharge terminal.

[0038] The present invention can be implemented both in vehicles whose powertrain is solely of the internal combustion thermal type and in vehicles of the rechargeable or non-rechargeable hybrid type whose powertrain comprises both an internal combustion powertrain stage and an electric powertrain stage, whether these two stages are coupled mechanically or electrically, for example according to an LV148 architecture of type P0, P1, P2 P3 or P4.

DETAILED DESCRIPTION

[0040] In an exemplary embodiment of an electrical energy production system S illustrated by the, a vehicle V with a thermal engine 10, equipped with an energy recovery and storage kit, produces, by means of an energy conversion unit 11, electrical energy at a direct voltage of 48 V which is stored in on-board electrochemical electrical energy storage modules 12 via a management and distribution unit 13. The energy conversion unit 11 is also provided for recharging via a DC / DC conversion unit 14 a low voltage 12V or 24V battery 15 dedicated to powering the generic equipment and accessories of the vehicle V.

[0041] The management of energy flows from the thermal engine 10 to the on-board storage modules 12 is ensured by an electronic control unit (ECU) 16.

[0042] The energy recovery and storage kit includes, as a practical example, the energy conversion unit 11, the electronic control unit 16, the on-board energy storage modules 12 and the management and distribution unit 13.

[0043] The vehicle V is also equipped with a wireless communication unit 17 connected to the electronic control unit 16 and intended to communicate with remote computing resources within a computing cloud 3.

[0044] The management and distribution unit 13 is associated with a mechanical and connection receiving base for the removable energy storage modules 12. These storage modules 12 are equipped with wireless communication means and data storage means.

[0045] Another key component of the energy production system S is a fixed installation such as a housing unit H. This housing unit H comprises a local electrical network 2 built around an electrical energy distribution and dispatch unit 21 controlled by an energy management unit 20 capable of communicating via wireless communication protocols with other communicating equipment inside the housing unit H or outside via the cloud 3.

[0046] The local electrical network 2, which may for example be completely autonomous or connected to an electrical distribution network, comprises a unit 23 for receiving removable electrical energy storage modules, a connector block 24 provided to receive a discharge socket at the end of an electrical cable connecting energy storage modules arranged in a vehicle, solar panels 22 arranged on the roof of the housing unit H and several electrical energy consuming devices including an electric radiator 25 shown in.

[0047] We will now describe, with reference to, a first example of energy transfer implemented in the energy production system according to the invention. In this first example, the driver of the vehicle V has removed a removable energy storage module 12 from the receiving base 13 of his vehicle and takes it into the housing unit H. This driver then places and connects the module 12 on the receiving unit 23. The communicating storage module 12 then exchanges information with the energy management unit 20 of the housing unit H. This information contains data on the state of charge (SOC) of the storage module, possibly on its state of health (SOH) and data estimating the carbon footprint and carbon dioxide emissions induced by the production of electrical energy which has just been transferred into the housing unit H.

[0048] In a second example of energy transfer illustrated by the, the driver connected the management and distribution unit 13 integrated in his vehicle V to the connector block 24 installed on a wall of the housing unit H, via an electric cable 26 adapted for the transfer of energy from the vehicle to the fixed installation.

[0049] We will now describe, with reference to the, the main steps of the electrical energy production method according to the invention. At the initiation of the method implemented in a vehicle equipped with the electrical energy recovery and storage (EES) kit, parameters characterizing the powertrain (GMP) of the vehicle are collected and energy recovery instructions are entered. These energy recovery instructions may, for example, be to accept a predetermined excess fuel consumption, or to convert deceleration energy, in particular during braking. This instruction entry could also be carried out by means of a selector having several angular positions, each corresponding to a recovery mode, or via a touch-sensitive graphical user interface.

[0050] While the vehicle is moving, the energy converter located downstream of the powertrain will be controlled by the electronic control unit 16 (ECU) according to the GMP parameters and the energy recovery instructions. The electrical energy thus obtained is transferred by internal connecting cables to the energy storage modules 12 via the management and distribution unit 13 which is also controlled by the electronic control unit ECU 16. The storage modules are then charged until the maximum charge level is reached or until the vehicle stops when its final destination has been reached.

[0051] While the vehicle is moving, engine data, including torque, and geolocation data are collected. The state of charge (SOC) of the energy storage modules is determined in real time or near real time. All of this collected data is used to determine an estimate of the CO2 emissions induced by the on-board electrical energy production. This estimation calculation can be carried out either by information processing means embedded in the vehicle, or by a remote IT resource such as a dedicated server accessible via the cloud.This server can operate a SaaS (Software as a Service) application accessible on a smartphone or any other connected communication equipment, the function of which is to provide users of the energy production method and system according to the invention with a dashboard summarizing and illustrating the characteristics of the energy thus produced in terms of CO2 emissions and possibly cost compared with other available energy sources.

[0052] At the end of the vehicle's movement, energy stored in the vehicle's storage modules can then be transferred to the fixed installation as just described with reference to Figures 2 and 3. The data collected and stored during the energy production process as well as the estimation data are transmitted to the energy management unit of the fixed installation which will use them to optimize the use of the different energy sources available at the fixed installation. The energy management unit implements in particular an arbitration algorithm processing the CO2 emission estimation data and the comparative energy cost.

[0053] With reference to which has common references with Figures 1 to 3, a hybrid propulsion vehicle V' can be used for the production of electrical energy according to the invention. This vehicle is for example provided with a powertrain 10' comprising an internal combustion powertrain stage 100 and an electric powertrain stage 110. These two stages are for example mechanically coupled and the electric propulsion stage 110 is electrically coupled to the electrical conversion unit 11, in practice an electric generator integrated in the reversible electric powertrain stage 110 and to the battery energy storage unit 12 via the management and distribution unit 13.

[0054] Of course, the present invention is not limited to the exemplary embodiments which have just been described and many other embodiments can be envisaged without departing from the scope of the invention.

[0055] Thus, the method for producing electrical energy according to the invention can be implemented in any type of motor vehicle, in particular a private vehicle, utility vehicle, bus, coach, heavy goods vehicle or construction site vehicle, for civil or defense applications, provided that this vehicle is powered by a power unit using a liquid or gaseous fuel and having an energy efficiency expected from an internal combustion engine or a fuel cell.

[0056] The system and method for producing electrical energy according to the invention can also be implemented in a nautical or aerial vehicle. The energy thus produced and stored in removable modules can then be used in a delayed manner in a ground installation or in any other remote installation.

[0057] Furthermore, the components of the energy recovery and storage kit fitted to a vehicle can be either standard equipment available on the market or components designed specifically for this kit.
