Description

[0001] The present disclosure relates to vehicles and in particular to architectures for vehicle-to-vehicle charging or vehicle-to-load operations.

[0002] Modern vehicles (e.g., a passenger car, motorcycle, boat, or any other type of motor vehicle) can be equipped with one or more batteries to provide electrical power to various vehicle systems. For example, an electric vehicle may contain one or more batteries to provide electrical power to one or more electric motors that propel the vehicle. This configuration of a vehicle is called a battery electric vehicle (BEV). Other types of vehicles may also be equipped with batteries, such as internal combustion engine vehicles, hybrid electric vehicles, and / or the like, including combinations and / or multiple types thereof.

[0003] Vehicle-to-vehicle charging (V2V charging) is a technique for transferring stored electrical energy from one vehicle (a source vehicle) to another (a destination vehicle). V2V charging can support bidirectional charging technology, enabling both charging and discharging of energy between vehicles. V2V charging can be particularly useful in emergency situations or remote areas where conventional charging infrastructure is unavailable. It operates via a direct current (DC) or alternating current (AC) connection between the vehicles. Vehicles equipped with V2V capabilities can share energy with each other, which can extend driving range or assist vehicles with depleted batteries.

[0004] Vehicle-to-load (V2L) is a technology that transfers electrical power from the vehicle (the source vehicle) to an electrical load connected to the vehicle. For example, electrical power can be transferred from one or more of the vehicle's batteries to a system or device connected to the vehicle that operates using the vehicle's electrical power. This allows the vehicle to supply electrical power in various situations where electrical power may not be available, such as during a power outage, at a location without electrical power (e.g., a campsite, a construction site), and / or similar situations, including combinations and / or multiple scenarios. As an example, a vehicle with V2L capabilities can be used to charge another electric vehicle.As another example, the vehicle may contain one or more electrical outlets into which any suitable device (e.g. a lamp, a coffee machine, an air compressor and / or the like, including combinations and / or several thereof) can be plugged.

[0005] Vehicles with internal combustion engines, such as plug-in hybrid electric vehicles and hybrid electric vehicles, can use their internal combustion engines to generate electrical power that can be used for V2V charging or V2L operations. It is desirable to provide an architecture for V2V charging or V2L operations that uses a direct power connection from a generator in the source vehicle to supply electrical power for these operations.

[0027] Further features, advantages and details appear only as examples in the following detailed description, which refers to the drawings; they show: Fig. 1 an illustration of vehicle support architectures for vehicle-to-vehicle charging or vehicle-to-load according to one or more embodiments; Fig. 2A a block diagram of a vehicle-to-vehicle charging or vehicle-to-load system according to one or more embodiments; Fig. 2B a block diagram of a vehicle-to-vehicle charging or vehicle-to-load system according to one or more embodiments; Fig. 3A a block diagram of a circuit for vehicle-to-vehicle charging or vehicle-to-load according to one or more embodiments; Fig. 3B a block diagram of a circuit for vehicle-to-vehicle charging or vehicle-to-loading according to one or more embodiments; Fig. 3C a block diagram of a circuit for vehicle-to-vehicle charging or vehicle-to-loading according to one or more embodiments; Fig. 3D a block diagram of a circuit for vehicle-to-vehicle charging or vehicle-to-load according to one or more embodiments; Fig. 3E a block diagram of a circuit for vehicle-to-vehicle charging or vehicle-to-load according to one or more embodiments and Fig. 4 a flowchart of a process for vehicle-to-vehicle loading or vehicle-to-load according to one or more embodiments. DETAILED DESCRIPTION

[0028] The following description is merely exemplary and is not intended to limit the present disclosure, its application, or uses. It should be understood that throughout the drawings, corresponding reference numerals denote similar or corresponding sections and features. As used herein, the term "module" refers to a processing circuit arrangement that may include an application-specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or grouped) with memory executing one or more software or firmware programs, a combinational logic circuit, and / or other suitable components providing the described functionality.

[0029] As used herein, the term “controller” (e.g., a load controller, which is further described herein) refers to a dedicated controller containing a processor and memory, a general-purpose controller containing control modules configured to implement a control process using the dedicated controller, a network of several different controllers communicating with each other, each containing processors and memory and configured to implement the control process together, and any similar configuration for implementing the control process.

[0030] One or more embodiments described herein provide architectures that enable vehicle-to-vehicle charging or vehicle-to-load charging. For example, a vehicle may be configured to provide direct current (DC) electrical power (e.g., essentially 400-800 V) and / or alternating current (AC) electrical power (e.g., essentially 110-120 Vac and / or essentially 220-240 Vac) to another vehicle or load electrically connected to a vehicle. According to one or more embodiments, one or more of the embodiments described herein may be implemented at further AC and / or DC voltage levels.

[0031] The propulsion systems of existing hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) use an on-board charging module (OBCM) to charge the vehicle's battery from the grid. When vehicle-to-vehicle (V2V) charging is performed, the vehicle (e.g., an HEV or PHEV) often employs a DC-DC converter to transfer electrical power from the source vehicle (e.g., the vehicle providing electrical power) to the destination vehicle (e.g., the vehicle receiving electrical power from the source vehicle). Such a DC-DC converter can be a bidirectional DC-DC converter, a fuel cell DC-DC converter, and / or similar devices, including combinations and / or multiple types.In some cases, such HEVs or PHEVs may use an external V2V charging architecture or may use an electronic multi-function drive system with increased power supply capability for V2V DC charging in electric vehicles.

[0032] However, each of these existing solutions uses a DC-DC converter, which adds weight, complexity, and additional inefficiencies to the vehicle. It is desirable to provide an architecture for V2V charging or V2L operations that uses a direct power connection from a generator in the source vehicle to provide electrical power for V2V charging or V2L operations without the DC-DC converter of existing solutions.

[0033] One or more embodiments described herein address these and other shortcomings by providing architectures for vehicle-to-vehicle or vehicle-to-load charging. According to one or more embodiments, an electrical architecture is provided that enables V2V DC charging in a plug-in hybrid electric vehicle (PHEV) or a hybrid electric vehicle (HEV) with a motor-generator driven by an internal combustion engine (ICE) and an inverter that regulates the charging voltage and current. That is, one or more embodiments allow a PHEV or an HEV containing an ICE, a generator set, and an inverter to directly charge another vehicle at the power output of the generator. One or more embodiments provide a direct power connection from the generator set in a V2x AC mode.One or more embodiments eliminate the DC converter that is conventionally implemented for V2V charging and / or V2L operations.

[0034] One or more embodiments described herein can be applied to any suitable hybrid vehicle, such as mild hybrids, full hybrids (e.g., parallel hybrids and series hybrids), plug-in hybrids, electric vehicles with range-extended hybrid technology and / or the like, including combinations and / or several thereof.

[0035] It must be acknowledged that the functionality of any vehicle implementing one or more of the embodiments described herein is enhanced. In particular, one or more of the embodiments described herein offer significant benefits and advantages, especially in improving the functionality of hybrid electric vehicles. For example, by integrating a direct power connection from a generator set, these embodiments eliminate the need for a conventional DC-DC converter, reducing weight, complexity, and inefficiencies. This streamlined architecture enables more effective V2V charging and V2L operations, providing a cost-effective solution that minimizes additional hardware requirements.One or more embodiments provide the ability to adjust the output voltage and current based on receiver requirements, ensuring optimal power distribution and improving the vehicle's adaptability to various charging scenarios. Furthermore, the use of a separately excitable machine or one with internal permanent magnets enables precise regulation of the power output, enhancing overall energy management within the vehicle. These innovations not only improve the vehicle's operational efficiency but also expand its utility in diverse environments by providing enhanced functionality, offering users greater flexibility and reliability in power management.

[0047] According to one or more embodiments, the battery 102 can be selectively disconnected from a propulsion bus (not shown) of the vehicle 100 during V2x mode using the generator (e.g., a generator set). According to one or more embodiments, the battery 102, in conjunction with twin propulsion motors and inverters, can be used as a step-down, step-up, or step-down / step-up converter for V2V DC fast charging using energy available from the battery 102.

[0048] According to one or more embodiments, the generator set can use an internal permanent magnet machine (IPM machine) and / or a separately excitable machine (SEM).

A power machine controller (not shown) controlling an ICE 104 communicates with the charging controller 110 to set the output voltage and current at the vehicle-side power outputs 316.In this embodiment, the SEM 203 can be used as a generator capable of regulating both the magnitude and frequency of the alternating current produced by the generator while operating the ICE 104 at a constant speed of essentially 60 Hz and adjusting the excitation of the SEM 203 to provide essentially a 120 VAC single-phase output, or using two of the three phases to provide a phase split of essentially 120 VAC and essentially 208 VAC when V2L operations are used. According to one or more embodiments, the relays can bypass the propulsion bus when electrical power is routed from the SEM 203 (e.g., the generator set 201) to the external load 342.

[0080] With reference to Fig. Path 305 represents the flow of electrical power in circuit 300 from generator set 201 to a vehicle-to-everything (V2x) device 360 ​​via a DC bus to the OBCM 326 and the charging access point 324, as shown.
