TITLE: ELECTRO THERMAL CUSTOM CONNECTORINVENTORS: DAVID ROBERT ARFTPRAHIT DUBEYASSIGNEE: SKYLINE MOBILITY, INC.FIELD

[0001] The present disclosure generally relates to electric vehicle (EV) charging systems and more particularly to an electro-thermal connector for use in an electric vehicle charging system.BACKGROUND

[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may be inventions.

[0003] Two or Three Wheeled EVs, such as electric two wheelers (“e2Ws”), e- Scooters, electric bikes, e-Motorcycles, e-Mopeds, hoverboards, and trikes comprise EV batteries which can be charged and discharged many times during their lifespan.

[0004] EV batteries may be charged using various systems. Many charging stations, such as Level 1 and Level 2 AC charging stations, provide an alternating current (“AC”) power supply to an EV, and the EV comprises converters to convert the power from AC to direct current (“DC”) which is usable by the EV motor. EV vehicles that use AC charging stations require large converters that are fairly slow. Two or Three Wheeled EVs are often too small to include converters large enough to quickly convert power from AC to DC. Some charging stations, such as Level 3 charging stations or DC Fast Chargers (“DCFC”). comprise large converters which take the AC power supply and convert to it to DC, which is then provided directly to the EV battery. DCFC stations comprise large converters configured to convert the AC input to a high-power DC output. Due to the size constraints of Two or Three Wheeled EVs, these vehicles may be charged much quicker and more efficiently with DCFC systems. However, DCFC can also cause EV batteries to reach high temperatures during charging. EV Battery' Management System (“BMS”) may slow down charging toensure unsafe temperatures are not reached by the EV battery. However, this may, especially in hot climates, cause charging to slow or stop.

[0005] Many full size EV s contain advanced cooling systems to ensure EV batteries do not overheat during changing. However, smaller EVs, such as Two or Three Wheeled EVs, do not have the space available for these cooling systems and primarily use air cooling systems, such as passive or active air-cooled batteries, to prevent temperature rise during charging. These air-cooling systems may not sufficiently cool the EV battery during charging to prevent parasitic losses and overheating of the battery. Conventional methods of cooling EVs are inefficient at cooling and therefore limit the rate at which the battery can be charged due to thermal and safety or reliability implications.

[0006] Accordingly, there is a need for cooling and thermal management systems for Two or Three Wheeled EVs.BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The subject matter of the present disclosure is particularly pointed out and distinctly claimed in the concluding portion of the specification. A more complete understanding of the present disclosure, however, may best be obtained by referring to the following detailed description and claims in connection with the following drawings. While the drawings illustrate various embodiments employing the principles described herein, the drawings do not limit the scope of the claims.

[0008] FIG. 1 illustrates an exemplary charging ecosystem, in accordance with various example embodiments.

[0009] FIG. 2 illustrates a schematic view of a charging ecosystem, in accordance with various embodiments.

[0010] FIG. 3 illustrates a perspective view of a charging connector for use in a charging ecosystem, in accordance with various embodiments.

[0011] FIG. 4 illustrates a method for charging an electric vehicle, in accordance with various embodiments.DETAILED DESCRIPTION

[0012] The following detailed description of various embodiments herein refers to the accompanying drawings, which show various embodiments by way of illustration. While these various embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, it should be understood that other embodiments may be realized and that changes may be made without departing from the scope of the disclosure. Thus, thedetailed description herein is presented for purposes of illustration only and not of limitation. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, connected, or the like may include permanent, removable, temporary, partial, full or any other possible attachment option. Additionally, any reference to without contact (or similar phrases) may also include reduced contact or minimal contact. It should also be understood that unless specifically stated otherwise, references to "a.” "an” or "the " may include one or more than one and that reference to an item in the singular may also include the item in the plural. Further, all ranges may include upper and lower values and all ranges and ratio limits disclosed herein may be combined.

[0013] Smaller electric vehicles, such as electric scooters or electric motorcycles may include a thermal management system for a battery system of the electric vehicle. The conventional wisdom for attempting to fast charge electric scooters or electric motorcycles is to use passive or active air-cooled batteries. However, this has heat rejection limitations and therefore limits the charging speed. Disclosed herein is a charging system that utilizes an offboard liquid cooled thermal management system as described further herein.

[0014] To facilitate fast charging via a liquid cooled thermal management system, the thermal management system on-board a smaller electric vehicle would have to be sized larger than if the thermal management system were sized solely based on thermal management parameters during operation of the smaller electric vehicle. Accordingly, by incorporating a thermal management system into an electrical vehicle as described further herein, a size of a thermal management system on-board a smaller electric vehicle, such as an electric scooter or an electric motorcycle can be greatly reduced while still being capable of utilizing fast charging.

[0015] Disclosed herein is a charging connector for use in an electric vehicle charging system. The charging connector includes an electrical interface and a thermal interface. The charging connector includes a connector interface. The connector interface is configured to mate with a charging interface of an electric vehicle. In various embodiments, in response to coupling the connector interface to the charging interface, a charging system can be electrically and thermally coupled to the charging system as described further herein. Accordingly, the connector interface can include a liquid supply and a liquid return fitting.

[0016] Disclosed herein is a charging connector configured with drip free fluid connections (e.g., a return connection and a supply connection). A charging handle for an electric vehicle can include the charging connector. The charging connector can allow a userto make a single motion to connect the charging connector to a charging interface of an electric vehicle. In response to forming the connection, a circuit is established between an onboard thermal management system of an EV and an external higher capacity thermal management system to facilitate fast charging. With the electrical connections made, the charging function can proceed. With the fluid connections made, the coolant loop can now activate cycling cooled fluid into the vehicle to absorb and extract heat from the components like the battery and power electronics. In various embodiments, heat removal during charging allows the performance to remain high for energy transfer into the vehicle (i.e., charging current can remain relatively high because the batten- and electrons are kept within an operating range).

[0017] Referring now to FIGs. 1 and 2, a charging ecosystem 10 is illustrated, in accordance with various embodiments. The charging ecosystem 10 includes an electric vehicle 100 and a charging system 200.
