Description

Technical Field

[0001] This invention relates to a modular integrated power system for electric land and sea vehicles, energy storage systems, and electric vehicle conversion. Background Technology

[0002] For different components to work together in an electric vehicle system, they must be compatible. In the prior art, compatibility issues arise when integrating components from different manufacturers. This negatively impacts the overall system performance. In existing electric systems composed of combinations of different components, several safety issues exist due to system complexity and integration problems. Components that cannot operate in a mutually compatible manner can lead to system failures and safety problems. Existing electric vehicle power conversion systems are often insufficient to provide customized solutions, limiting their adaptability to different vehicle types. In particular, the limited flexibility of the integration process for different vehicle models and types makes it difficult for manufacturers to quickly adapt to the market.

[0003] The prior art includes research by Nan Li et al. involving an integrated electric vehicle power conversion system using a modular multilevel converter. With such a monolithically developed system, the inverter component in the electric vehicle can be used for both charging and motor drive functions without the need for additional units. In other words, an integrated product is provided by collecting the inverter and charger components that exist in the electric vehicle into a single unit. This integration is limited to the inverter and charger, and full integration has not yet been achieved through this research [1].

[0004] In existing electrical systems for electric vehicles, components such as the power distribution unit, drive battery, on-board charger (OBC), DC / DC converter, motor drive, battery management system, and vehicle control unit (VCU) are placed in different locations within the vehicle, thus requiring the use of high-voltage cables between these components. These cables are routed through appropriate surfaces and areas on the vehicle. This results in increased cable cost and weight due to the longer cable lengths. Furthermore, the placement of components with different technical characteristics in separate areas within the system in existing electrical systems for electric vehicles leads to space loss and complicates the vehicle's structure.

[0005] The prior art mentioned earlier in the integration section includes the research by Nan Li et al., which involves an integrated electric vehicle power conversion system using a modular multilevel converter. The modularity in this study is the modularity that can only be used for modular multilevel converters. In other words, it is not possible to say that the complete modularity provided by a single unit can be achieved in this study [1].

[0006] The following issues necessitate the introduction of a highly modular and integrated electric power system for electric land and sea vehicles, energy storage systems, and electric vehicle conversion, where all these problems are eliminated: compatibility issues arising in existing electric conversion systems for electric vehicles during the integration of components from different manufacturers, thus negatively impacting the overall system performance; complexity and integration issues in the system, leading to certain safety problems in existing electric systems formed by combining different components, and components not operating in a mutually compatible manner, resulting in system failures; existing electric conversion systems for electric vehicles are often insufficient to provide customized solutions, thus limiting their adaptability to different vehicle types; and integrated electric vehicle power conversion using modular multilevel converters in existing technologies. In the system, only limited integration is achieved, such as combining inverter and charger components present in electric vehicles into a single unit, while modularity is limited to modularity involving modular multilevel converters; in the prior art power systems for electric vehicles, placing power distribution units, drive batteries, on-board chargers (OBC), DC / DC converters, motor drives, battery management systems, and vehicle control units (VCUs) in different locations within the vehicle requires the use of high-voltage cables between components, and the increased cable length leads to higher cable costs and weight problems because these cables are routed through appropriate surfaces and areas within the vehicle; and in the prior art power systems for electric vehicles, positioning components with different technical characteristics in separate areas within the system results in space loss and a more complex vehicle structure. Summary of the Invention

[0007] This invention describes a modular integrated power system for electric land and sea vehicles, energy storage systems, and electric vehicle conversion. The invention introduces a power system in which compatibility issues between different components are eliminated, and integration between components is increased. Components used in electric land and sea vehicles and located in different parts of the vehicle (such as drive batteries, on-board chargers (OBC), DC / DC converters, motor drives, battery management systems, vehicle control units (VCU), insulation measurement devices (IMD), power distribution units, and battery heating systems (PTC)) are combined to form an integrated and modular system. Furthermore, the system of this invention is an integrated and modular system that integrates solar panels into a single unit that allows charging by the solar panels. The system of this invention eliminates expensive high-voltage cables used for power distribution between components such as the OBC, DC / DC converter, motor drive, power distribution unit, and battery heating system (PTC) powered by the drive battery, minimizing cable length, preventing cable heating problems by minimizing energy loss in the cables, and improving system efficiency.

[0008] The integration provided in this invention facilitates the application of power systems to transportation and energy storage systems by incorporating complex electrical / electronic (E / E) systems into a single unit. Significant cost and weight advantages are achieved in the system of this invention by reducing expensive high-voltage cables. Electrical safety is ensured through insulated cables in high-voltage transportation systems or energy storage solutions. It also provides improvements in shock safety by having a closed structure in the integrated power system, and by utilizing the integrated power system to collect and eliminate these insulated cables in a single unit and minimize cable length.

[0009] This invention provides a modular integrated power system for electric land and sea vehicles, energy storage systems, and electric vehicle conversion with increased reliability. The system described in this invention ensures component compatibility, prevents related errors, and increases system reliability.

[0010] The object of this invention is to provide an electric system in which compatibility problems between different components are eliminated and integration between components is increased. In the system of this invention, compatibility problems between different components are eliminated. Compatibility problems commonly encountered in electric vehicles are caused by a lack of complete integration of components. The system described within this scope ensures component compatibility, prevents related errors, and increases system reliability. For different components to work together in an electric vehicle system, they must be compatible. In the prior art, compatibility problems arise when integrating components supplied from different manufacturers. This negatively impacts the overall performance of the system.

[0011] The integration provided in the system of the present invention facilitates the application of electric systems to vehicles by bringing together complex electrical / electronic (E / E) systems into a single unit.

[0012] Another object of the present invention is to provide a modular power system for electric land and sea vehicles and for the conversion of electric vehicles. The present invention integrates components such as drive batteries, OBCs, DC / DC converters, motor drives, battery management systems and vehicle control units (VCUs), insulation measurement devices (IMDs), power distribution units, and battery heating systems (PTCs) into an integrated and modular system. Furthermore, the present invention introduces an integrated and modular system that connects and collects solar panels in a single unit that allows charging via solar panels.

[0013] In the system of this invention, significant cost and weight advantages are achieved by reducing expensive high-voltage cables. In the system of this invention, the assembly of components powered by high-voltage batteries in a single unit provides cost and weight advantages by reducing the use of expensive and heavy high-voltage (HV) cables. In current systems, the use of high-voltage cables is very common. These cables are heavy in terms of both cost and weight, thus increasing the overall cost and weight of the vehicle.

[0014] This invention provides a modular integrated power system for electric land and sea vehicles with increased reliability, as well as for the conversion of electric vehicles. Compatibility issues commonly encountered in electric vehicles arise from a lack of complete component integration. The system described in this invention ensures component compatibility, prevents related errors, and increases system reliability within this scope. Attached Figure Description

This increases the overall reliability of the system, reduces the failure rate, and ensures the lifespan of the vehicles.

[0044] Because the integrated power system of this invention is provided in modular power systems for electric land and sea vehicles and for the conversion of electric vehicles, faster data exchange and more efficient control are offered. This helps to improve vehicle performance and enhance acceleration and response times.

[0045] In the integrated power system of the present invention, components can be updated modularly. The modular battery module (1) included in the power system of the present invention is in the range of 48V to 1500V, and in one embodiment of the present invention, 48V, 60V, 72V, 96V and 108V options are available. Furthermore, in the modular integrated power system of the present invention, the power distribution module (2) has a modular structure with and without air conditioning, depending on the different power outputs required to meet the needs of different auxiliary systems. For vehicles using the power systems of the present invention, including the on-board charger (4) (OBC) and the DC / DC converter module (5), the on-board charger (4) (OBC) can be obtained from 3.3kW to 22kW, both air-cooled and liquid-cooled; in one embodiment of the invention, the DC / DC converter module (5) can be obtained with a power output of 0.5kW to 5kW in the range of 48V to 1500V, providing modularity with input voltages of 48V, 60V, 72V, 96V, 108V, 120V, 144V, 192V, 240V, 345V, 400V, 600V, 800V, and 900V and output voltages of 12V and 24V. Depending on the input voltage of the asynchronous and synchronous motor types used in the system, the inverter motor drive module (6) provides modular inverter motor drive module (6) options from 5kW to 50kW.

[0046] Since the power system of the present invention is an integrated power system, it contains all the components required for the operation of the electric vehicle. A modular battery module (1) with a cell-to-pack structure in the system of the present invention serves as the energy storage portion of the integrated power system. The modular battery module (1) provides the energy required by the components in the integrated power system during driving. Furthermore, the modular battery module (1) can be charged during driving using the energy recovery braking feature provided by the inverter motor drive module (6). During charging, the on-board charging component of the integrated power system of the present invention provides charging for the modular battery module (1). The power distribution module (2) is connected to the system using two busbars extending from the modular battery module (1) and performs the fuse and contactor functions for the components powered by the modular battery module (1). The power distribution module also includes a pre-charging circuit. A DC / DC converter module (5) component is connected to both the power distribution module (2) and the low-voltage battery (9) of the electric vehicle. In this way, it uses the energy received from the modular battery module (1) to charge the system's low-voltage battery (9) and meets its requirements during operation. The inverter motor drive module (6) is connected to the power distribution module (2) in the integrated power system and uses the energy received from there to perform the task of driving the electric motor.

[0047] When used in electric marine vehicles, the modular integrated power system of the present invention is installed in the motor bay of the vessel. The output of the DC / DC converter module (5) leading from the integrated power system is connected to the low-voltage battery (9). Therefore, the integrated power system charges the low-voltage battery (9) during operation and charging, meeting the system's energy requirements. An AC charging cable leading from the integrated power system is inserted into a socket connection, enabling the electric marine vehicle to be charged via the socket while docked in port. A DC charging output socket leading from the integrated power system is installed in a suitable area on the ship's deck. A motor cable leading from the integrated power system is installed to the motor, allowing the integrated power system to control the motor.

[0048] When the modular integrated power system of the present invention is used in an electric land vehicle, the integrated power system is mounted on the chassis of the vehicle. The output of a DC / DC converter module (5) derived from the integrated power system is connected to a low-voltage battery (9) and a low-voltage system. The low-voltage system here may refer to a car radio, vanity light, or automatic window opening and closing system. Thus, the integrated power system charges the low-voltage battery (9) during driving and charging processes and meets the system's needs. Modularly provided sockets, such as CCS (combined charging sockets (CCS1 or CCS2)) AC charging sockets or DC charging sockets, are mounted on the vehicle chassis, derived from the integrated power system. A motor cable derived from the integrated power system is connected to the motor, enabling the integrated power system to control the motor.

[0049] During the conversion to electric vehicles, components unique to internal combustion engine vehicles, such as the internal combustion motor, cooling system, and fuel tank, are removed from the vehicle, and the integrated electric system of the present invention is instead installed in the motor compartment or chassis of the vehicle. The output of the DC / DC converter module (5) from the integrated electric system is connected to the low-voltage battery (9) and the low-voltage system. Therefore, the integrated electric system charges the low-voltage battery (9) during driving and charging processes and meets the system's energy requirements. Modularly provided sockets, such as CCS (combined charging sockets (CCS1 or CCS2)) AC charging sockets or DC charging sockets, are installed on the vehicle chassis, leading from the integrated electric system. Motor cables leading from the integrated electric system are connected to the motor, allowing the integrated electric system to control the motor.

[0050] The overall objective of this invention is to introduce an integrated power system for electric land vehicles, electric marine vehicles, and electric vehicle conversion companies. In the power system of this invention, key components such as the power distribution module (2), the modular battery module (1) serving as the drive battery, the DC / DC converter module (5), the on-board charger (4) (OBC), the inverter motor drive module (6), the battery management system (13) (BMS), and the vehicle control unit (12) (VCU) used in the electric vehicle are integrated into a single unit. It combines the modular battery module (1) serving as the drive battery, the on-board charger (4) (OBC), the DC-DC converter module (5), the inverter motor drive module (6), the battery management system (13) (BMS), the vehicle control unit (12) (VCU), the insulation measurement device (10) (IMD), the power distribution module (2), and the modular battery module heating system (11) (PTC heater) into an integrated and modular system. It also allows charging via solar panels. The system eliminates expensive high-voltage cables used for power distribution between components such as the on-board charger (4) (OBC), DC / DC converter module (5), inverter motor drive module (6), power distribution module (2), and modular battery module heating system (11) (PTC heater) powered by modular battery module (1) as drive battery, minimizing cable length and preventing cable heating problems by minimizing energy loss in the cables, thus improving system efficiency. This integration eliminates complex wiring networks, simplifying and accelerating the production process in electric land vehicles, electric marine vehicles, and vehicles for electric vehicle conversion companies. In the power system of this invention, complex electrical / electronic (E / E) configurations are collected in a single unit, providing convenience for integration and conversion. Therefore, more efficient, cost-effective, and high-performance electric vehicles can be produced.

[0051] Integrated electrical systems offer a more compact and modular structure during vehicle production, simplifying and accelerating the assembly process. This saves time and costs on the production line while simultaneously increasing production capacity. Furthermore, the reduction in the complexity of high-voltage cable routing and the resulting decrease in cable length reduces costs and vehicle weight, positively impacting vehicle performance and energy efficiency.

[0052] This invention aims to promote the adoption of electric vehicle technology and achieve environmental sustainability goals. Electric vehicles reduce carbon emissions and minimize environmental pollution by reducing the use of fossil fuels. The integrated electric system described in this invention makes a significant contribution to these goals by providing high-performance electric vehicles with less resource use and lower energy consumption.

[0053] The power system of this invention will meet the needs of L6 and L7 vehicle manufacturers, which have recently become prevalent around the world, and will also eliminate the challenges faced by electric vehicle conversion companies due to complex electrical / electronic (E / E) architectures.

[0054] Marine vehicles, especially those operating in tourist areas such as rivers and streams, cause serious damage to nature. Electrification of these vehicles is crucial to mitigating this damage. The power system of this invention avoids the challenges associated with the development of electric vehicles due to their complex electrical / electronic (E / E) architecture and accelerates the transition of these environmentally harmful vehicles to electric vehicles.
