Description

Device, method and system for managing predictable electric vehicle battery The present invention relates to an apparatus, method, and system for managing a predictable electric vehicle battery, and more specifically, to an apparatus, method, and system that can predict and prevent fires and failures of an electric vehicle battery in advance by monitoring the condition of the electric vehicle battery in real time based on artificial intelligence. Recently, as people's awareness of eco-friendliness changes and eco-friendly policies become a global trend, the market size and sales volume of eco-friendly vehicles, such as electric vehicles, are steadily increasing. Unlike conventional vehicles equipped with internal combustion engines such as diesel or gasoline engines, electric vehicles (EVs) generate driving force by supplying electrical energy from a high-voltage battery to an electric motor. Along with hydrogen vehicles, they are zero-emission, eco-friendly vehicles that do not use any fossil fuels. Since EVs operate by running on batteries, drivers must visit a charging station to recharge when the battery is depleted. Electric vehicles can overcome the disadvantages of the aforementioned internal combustion engine vehicles by driving electric loads using power supplied from their own battery packs during normal operating conditions, thereby enabling them to perform specific functions even when the engine is off. In addition, when an electric vehicle is connected to a charger, the charging process of the battery pack is initiated, and the electrical load is driven by power supplied from the charger instead of the battery pack. In order to maintain certain functions during charging, power from the charger must be continuously supplied to the electrical load. However, if the charger continues to supply power even after the battery pack is fully charged, there is a risk that the battery pack will be overcharged. When the battery pack is disconnected from the charger to prevent overcharging of the battery pack, the charger stops supplying power in response to the fact that the voltage of the battery pack is no longer detected, and as a result, certain functions cannot be maintained. Such electric vehicle batteries pose a risk of explosion due to changes in condition during use, so accurate diagnosis is required.
