==ELECTRIC POWER SOURCE CONTROL DEVICE, CONTROL METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18299805 titled 'ELECTRIC POWER SOURCE CONTROL DEVICE, CONTROL METHOD, AND STORAGE MEDIUM

==Simplified Explanation==

The abstract describes an electric power source control device that monitors the charging/discharging current of a low-voltage battery and detects abnormal connection states. When a predetermined operation is detected, the device determines if the charging/discharging current remains below a threshold value for a certain duration of time. If it does, the device controls an electric power converter and further determines if the state continues for a longer duration. If it does, the device identifies the connection state of the low-voltage battery as abnormal.

* Acquisition unit acquires charging/discharging current of a low-voltage battery
* Detection unit detects a predetermined operation executed with respect to a high-voltage battery
* Determining unit determines abnormality in connection state of low-voltage battery based on charging/discharging current
* Controls electric power converter when charging/discharging current remains below a threshold value for a certain duration of time
* Identifies connection state of low-voltage battery as abnormal when the state continues for a longer duration

==Potential Applications==
* Electric vehicles: The device can be used to monitor and control the power source in electric vehicles, ensuring the battery connection is functioning properly.
* Renewable energy systems: The device can be applied in renewable energy systems, such as solar or wind power, to monitor and detect abnormal connection states in the battery storage systems.

==Problems Solved==
* Detecting abnormal connection states: The device solves the problem of identifying abnormal connection states in low-voltage batteries, which can help prevent potential safety hazards or system failures.
* Efficient power conversion: By controlling the electric power converter based on the charging/discharging current, the device ensures efficient power conversion and optimal battery performance.

==Benefits==
* Safety: The device helps ensure the safety of the power source by detecting and addressing abnormal connection states in the low-voltage battery.
* System reliability: By monitoring and controlling the power source, the device enhances the reliability and performance of electric vehicles and renewable energy systems.
* Energy efficiency: The device optimizes power conversion by controlling the electric power converter, leading to improved energy efficiency and battery utilization.


==Original Abstract Submitted==

An electric power source control device includes an acquisition unit that acquires a charging/discharging current of a low-voltage battery, a detection unit that detects a predetermined operation executed with respect to a high-voltage battery, and a determining unit that determines presence/absence of an abnormality with respect to a connection state of the low-voltage battery, based on the charging/discharging current. When the predetermined operation is detected, the determining unit determines whether a state in which the charging/discharging current is no greater than a first threshold value continues for a first duration of time, controls an electric power converter when the state continues for the first duration of time, and further determines whether the state continues for a second duration of time longer than the first duration of time, and determines that the connection state of the low-voltage battery is abnormal when the state continues for the second duration of time.
