Abstract
Description
AREA
[0001] The present disclosure relates generally to a multi-charge connector for electric vehicles that enables interoperable charging according to the standards Type 2, CCS 2 and CHAdeMO. GENERAL STATE OF THE ART
[0002] Electric vehicle (EV) charging systems feature multiple connectors for alternating current (AC) and direct current (DC) charging, including Type 2, CCS, and CHAdeMO, each meeting specific regional and power requirements. AC charging is commonly used for residential and low-power applications, while DC fast charging supports rapid energy replenishment. However, the coexistence of multiple connector standards has led to a fragmented charging infrastructure, limited interoperability, increased deployment costs, and user inconvenience. Charging stations are often restricted to specific connector types, resulting in underutilization and limited accessibility. Consequently, there is a need for a unified charging connector capable of supporting multiple EV standards in a single, integrated device. SUMMARY
[0003] The subject matter of the present invention is defined in the claims. BRIEF DESCRIPTION OF THE FIGURES Fig. Figure 1 illustrates a multi-port charging connector for electric vehicles that enables interoperable charging according to the Type 2, CCS 2 and CHAdeMO standards. DETAILED DESCRIPTION OF THE INVENTION
[0004] The existence of multiple charging standards for electric vehicles, such as Type 2, CCS, and CHAdeMO, has led to a fragmented charging infrastructure, limited interoperability, inefficient use of charging stations, increased deployment costs, and user inconvenience, particularly in regions with different connectors. This highlights the lack of a unified and automated charging plug solution.
[0005] The present disclosure relates to a multi-charge connector for electric vehicles that combines several charging standards in a single device to overcome the limitations of conventional EV charging systems. The invention comprises a circular housing configured to accommodate a plurality of connectors, including a Type 2 connector, a CCS-2 connector, and a CHAdeMO connector, each mounted on a tooth of a spur gear arranged in a circular pattern. The spur gear is operatively connected to a DC motor and supported by ball bearings to enable smooth and precise rotational alignment of the selected connector along a specific axis of actuation corresponding to the vehicle's charging port.After alignment, a linear actuator, comprising an actuating element, a motor, a helical gear, and a shaft bearing, moves the selected connector from a rest position to a charging position by extending it toward the vehicle's charging socket, thus ensuring reliable electrical engagement. The actuator and alignment mechanisms are controlled by programmable microcontroller logic, enabling automatic connector selection based on vehicle inputs or user preferences. The invention further includes an extendable support stand connected to the housing via a hinge mechanism. Telescopic tube sections allow for height adjustment and mechanical stability during charging, thereby reducing stress on the connector interface. An outer cover encloses and protects the internal components from environmental influences.Through this integrated mechanical, electrical and control engineering architecture, the invention enables interoperable AC and DC charging across multiple EV standards using a single compact and automated connector system.
[0006] Fig.Figure 1 illustrates an arrangement 100 for a multi-port charging connector for electric vehicles, comprising a circular housing 102 that accommodates a variety of connectors, including a Type 2 connector, a CCS-2 connector, and a CHAdeMO connector, arranged within the housing. A rotary alignment mechanism 104 is provided, comprising a spur gear and ball bearings configured to selectively rotate one of the connectors and position it on a specific actuation axis. A linear actuator 108 is functionally connected to the housing and configured to actuate the selected charging connector from a rest position to a charging position, thereby enabling safe engagement with the vehicle's charging port.Arrangement 100 thus demonstrates the integration of several charging standards in a single device and shows the spatial arrangement of the housing, the plugs, the rotary alignment mechanism and the actuator in relation to each other.
[0007] Although the implementations for methods and systems for recommending one or more products to the buyer in real time are described in language relating to structural features and / or methods, it should be noted that the attached claims are not necessarily limited to the specific features or methods described. Rather, the specific features and methods are disclosed as examples of implementations for recommending one or more products to the buyer in real time.
