DESC:TECHNICAL FIELD
[0001] The present disclosure relates to a power distribution system for vehicles, and in particular, to a power distribution system that efficiently manages the electrical connection between a power source unit and various devices within a vehicle. Such a system is crucial for the reliable operation of a wide range of vehicles, including electric vehicles, hybrid vehicles, and other electrically powered vehicles.
BACKGROUND OF THE INVENTION
[0002] In recent years, there has been a growing reliance on public and cargo transportation, with a particular emphasis on light commercial multi-wheeled multi-track vehicles. These vehicles, which operate around the clock on roads, have witnessed a significant increase in numbers, especially in developing countries where they are considered a cost-effective mode of transport. Generally, such vehicles comprise a chassis structure supporting a body that is divided into a driver compartment and/or a passenger compartment for accommodating passengers. Some vehicles constitute monocoque construction of body which itself acts like a load bearing chassis or frame structure. Examples include three-wheeler passenger vehicles, four-wheeled vehicles, and multi-axle vehicles. Some variants of vehicles also feature a driver compartment mounted on the chassis structure. Some variants of vehicles also feature a loading compartment for transporting cargo, like three-wheeler passenger cargo vehicles. Further, these vehicles come in various powertrain configurations, ranging from internal combustion engines to electric motors, including hybrid and fully electric vehicles. Typically, these vehicles are equipped with rechargeable battery packs or fuel cells that supply electric power to electric motors and other vehicle components storing energy generated by the motor or charged from an external source. Other vehicle components include parts such as but not limited to a power distribution unit (PDU), charger, DC-DC, Vehicle Control Unit (VCU) / Control unit or the like.
[0003] To facilitate this electric power distribution, a Power Distribution Unit (PDU) is employed. The PDU connects the battery pack to a charger, a DC to DC converter, and a control unit within the vehicle through a connector and multiple cables. Specifically, the positive and negative terminals of the battery pack connect to the PDU via a connector, and the PDU's output links to control units, a DC to DC converter, and other vehicle components. Traditionally, the PDU and the battery pack are positioned at a considerable distance from each other on the vehicle and connected via thick high-voltage cables. This design makes cable routing challenging, necessitating different routing paths, increasing cable length, and requiring numerous heavy clips and clamps. Consequently, these complications lead to additional parts for the vehicle, weight and cost for the vehicle. Furthermore, different vehicle layouts demand various configurations and mounting arrangements for the PDU, further contributing to the vehicle's overall weight and cost.
[0004] Further, the packaging of the Power Distribution Unit (PDU) within the chassis or cabin of a vehicle presents several significant challenges. These challenges are driven by the need to optimize the use of space within the vehicle while ensuring the reliable and secure connection of the PDU components. The issues associated with PDU placement are exacerbated by the dynamic and sometimes harsh conditions that vehicles encounter during operation.
[0005] One of the primary challenges of integrating the PDU into the vehicle's chassis or cabin is the utilization of limited available space. Vehicles, particularly those configured for individual use or public transportation or cargo transport, are often engineered to maximize interior space for passengers, cargo, or other critical functions. This leaves limited room for additional components like the PDU, which plays a crucial role in distributing power from the vehicle's source unit, such as a battery or power supply, to various electrical devices within the vehicle.
[0006] Moreover, the constant vibrations generated by the vehicle's engine, road surface irregularities, and general vehicle motion can introduce dynamic stresses on the components of the PDU. These vibrations may stem from the internal combustion engine or the electric motor, causing components to shift or become loose over time. If not properly addressed, these vibrations can lead to a critical issue such as the potential loosening of connectors within the PDU.
[0007] When connectors become loose within the PDU, it can result in a dangerous situation e.g. short circuit, sparking, fire accident, etc. If these connectors are responsible for maintaining the electrical connection between the power source unit and the vehicle's components, a loss of connection could occur. This could potentially lead to the disassociation of the battery pack or power source from the vehicle, with severe consequences. Such disassociation can disrupt the operation of vital vehicle components, including control units, chargers, and DC to DC converters, and may pose a significant safety risk to both the vehicle and its occupants.
[0008] Therefore, there is a need of a simple and cost-effective solution which can obviates the above-mentioned problems.
[0009] The above information as disclosed in this background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Further, limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present disclosure and with reference to the drawings

The cables can be integrated with the power source unit (100a,) /battery pack through the guiding members/cable glands.
[0057] In an embodiment, by using different types of cables glands and/or cable out design, the power distribution can happen inside the housing with internal fuse and relay control.
[0058] In one embodiment, the battery pack(s) can be disposed below the driver seat in a front portion of the vehicle. In another embodiment, the battery pack can be disposed in lateral direction/ longitudinal direction of the vehicle.
[0059] In another embodiment, the battery pack can include low voltage connector. The guiding members/ cable glands (118, 120, 122, 124, 218, 220,302, 304) can be on either LH or RH side of the battery pack or from the top cover or the bottom cover.
[0060] The location of the devices such as iVCU, the DC-DC converter, the charger and other devices can define the location of the guiding members (118,120, 122, 124 218, 220, 302, 304) from the battery pack/housing (102).
[0061] As per an embodiment, some of the cables such as positive terminal cable connected to the battery, DC-DC converter cables, charger cables can be routed through a cut out in a floorboard of the vehicle on a left hand side or a right hand side. The negative terminal cable can be connected to the chassis of the vehicle for grounding.
[0062] The power distribution system disclosed herein addresses the challenges associated with efficiently managing the electrical connections within a vehicle. This system offers an innovative approach to organize and secure these connections, enhance cable routing and cable packaging in the vehicle by reducing the length of the cables which can be covered by any suitable covers, this reduces the chances of direct exposure of cables to users thereby enhancing safety.
[0063] The system is configured to accommodate one or more power source units. The one or more power source units may include batteries, power supplies, or other energy storage devices, depending on the specific requirements of the vehicle. The power source units serve as the primary energy source for the vehicle's components and devices.
[0064] The housing is configured to house the power source unit(s) and facilitate efficient cable management. This housing is configured with the one or more apertures intentionally positioned to allow the passage of the cables in an effective manner enabling ease of routing, coupling and flexibility of power source unit. The housing is configured to provide secure and organized storage for the power source unit(s).
[0065] The guiding members are configured to ensure that cables are safely routed and securely connected. These guiding members are configured with the apertures in the housing and work in conjunction with the housing to support and guide the cables. They play a crucial role in guiding and maintaining the stability and reliability of the cable connections.
[0066] Diverse cable types cater diverse electrical requirements of various vehicle components and devices. As such, the present invention is engineered to accommodate cables of different types, dimensions, and functional properties. This flexibility allows for the effective distribution of power to a wide range of components within the vehicle. For instance, the different cables can supply power of different voltage. In an exemplary embodiment, the cables can be made of same material or different materials.
