Description

Charging control apparatus and method for a charger The present invention relates to a charging control device and method for a charger, and more specifically, to a device and method for controlling the charging of a charger based on image analysis and shock detection of the charger and its surroundings. Consumer interest and demand for electric vehicles are increasing as they emerge as the most effective alternative for reducing greenhouse gas emissions and improving energy efficiency. Unlike conventional internal combustion engine vehicles, electric vehicles (EVs) require components such as batteries, electric motors, inverters, converters, and Battery Management Systems (BMS). Rechargeable secondary batteries are used for electric vehicles. Secondary batteries, which can be recharged and reused after use, are manufactured into battery modules or battery packs by connecting multiple battery cells in series according to the output capacity required by the electric vehicle, and are used as power sources for various electric vehicles. Secondary batteries are used in a wide range of fields, from small advanced electronic devices such as smartphones to electric bicycles, electric vehicles, and Energy Storage Systems (ESS). Meanwhile, a prerequisite for the widespread adoption of electric vehicles (EVs) is the establishment of charging infrastructure, including EV charging stations. EV charging stations generally receive power from the grid to perform slow or fast charging for electric vehicles. However, EVs can be exposed to various hazardous environments, such as fire or external impact, during charging. The problem is that requiring users or managers to stay near the vehicle while charging to monitor and inspect for these risks incurs significant costs. Figure 1 is a conceptual diagram of electric vehicle charging infrastructure. Figure 2 is a diagram showing the configuration of an on/off board charging system for an electric vehicle. Figure 3 shows the structure of a conventional fast charger installed at an electric vehicle charging station. FIG. 4 is a conceptual diagram of the operation of a charging control device according to an embodiment of the present invention. FIG. 5 is a flowchart of the operation sequence of a charging control method according to an embodiment of the present invention. FIG. 6 is a block diagram of a charging control device according to an embodiment of the present invention.

Terms such as first, second, A, B, etc., may be used to describe various components, but said components shall not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. The term "and/or" includes a combination of a plurality of related described items or any of a plurality of related described items.
