Description

Mobile Robotic Electric Vehicle Charger with Simultaneous Evacuation Control Function for Multiple Chargers in Case of Fire Mobile Robotic Electric Vehicle Charger with Simultaneous Evacuation Control Function for Multiple Chargers in Case of Fire The present invention relates to the field of electric vehicle charger technology, and more specifically, to a mobile robot electric vehicle charger capable of charging an electric vehicle using a mobile robot and improving safety by including a fire detection function. The technology underlying the present invention relates to existing stationary chargers and mobile robot electric vehicle chargers for charging electric vehicles. Conventional electric vehicle chargers are typically installed in fixed locations, and they operate by requiring users to travel to the charging station to charge their vehicles directly. This method relies on the physical location of the charging station; not only is time and energy consumed during the journey, but waiting times may also occur due to the limited capacity of the stations. Mobile robotic electric vehicle chargers were developed to overcome the limitations of stationary chargers and are designed to provide charging services close to users. However, existing mobile robotic chargers often suffer from issues such as being manually operated or failing to adequately ensure safety during the charging process. In particular, there is a lack of technical safeguards to detect and respond in real-time to accidents, such as fires, that may occur during the charging process. Therefore, there is a need to develop technology that enhances the automation and safety of mobile robotic electric vehicle chargers and enables the rapid detection and response to emergency situations, such as fires. This invention aims to solve these technical challenges. The prior art, domestic patent application 'KR20230045707A', includes content regarding a fire detection and early response system using an autonomous mobile robot. Figure 1 is a configuration diagram of the mobile robot electric vehicle charger of the present invention and a system utilizing the same. FIG. 2 is an exemplary diagram showing a manual type mobile robot electric vehicle charger of the present invention. Figure 3 is a flowchart illustrating a fire response algorithm using a manual type mobile robot electric vehicle charger of the present invention.

Various embodiments are described with reference to the drawings. In the present invention, various descriptions are provided to facilitate an understanding of the invention. However, it is evident that these embodiments can be practiced without such specific descriptions. The term "or" is intended to mean an implicit "or" rather than an exclusive "or." That is, unless otherwise specified or evident from the context, "X uses A or B" is intended to mean one of the natural implicit substitutions. In other words, if X uses A; if X uses B; or if X uses both A and B, "X uses A or B" may apply to any of these cases. Furthermore, the term "and/or" as used in this invention should be understood to refer to and include all possible combinations of one or more of the enumerated related items. Furthermore, the terms “comprising” and/or “comprising” should be understood to mean that such features and/or components are present. However, the terms “comprising” and/or “comprising” should be understood not to exclude the presence or addition of one or more other features, components and/or groups thereof. Additionally, unless otherwise specified or clearly evident from the context to indicate a singular form, the singular in the present invention and claims should generally be interpreted to mean “one or more.” And, the term “at least one of A or B” should be interpreted to mean “a case including only A,” “a case including only B,” and “a case combined with the composition of A and B.” Figure 1 is a configuration diagram of the mobile robot electric vehicle charger of the present invention and a system utilizing the same.
