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.
