ELECTRONIC DEVICE FOR ESTIMATING BATTERY STATE AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17720971 titled 'ELECTRONIC DEVICE FOR ESTIMATING BATTERY STATE AND OPERATING METHOD THEREOF
Simplified Explanation
The patent application describes an electronic device that can improve the accuracy of estimating the state of charge (SOC) of a battery. Here are the key points:
- The device includes a memory to store parameters of an electrochemical model that represents the battery.
- A sensor is used to measure the voltage of the battery.
- A processor is responsible for determining a correction amount for the SOC at a partially discharged point in time, where the SOC is adjusted to reduce the voltage difference between the estimated voltage from the electrochemical model and the measured voltage of the battery.
- The processor also estimates a cumulative SOC correction amount at a fully discharged point in time based on the correction amount determined earlier and a prediction curve for SOC correction amounts.
- Finally, the aging parameter of the electrochemical model is updated based on the estimated cumulative SOC correction amount.
Potential applications of this technology:
- Electric vehicles: Accurate estimation of battery SOC is crucial for optimizing the performance and range of electric vehicles.
- Portable electronics: Improved SOC estimation can enhance the battery life and performance of smartphones, laptops, and other portable devices.
- Renewable energy systems: Battery SOC estimation is important for efficient energy storage and management in renewable energy systems.
Problems solved by this technology:
- Inaccurate SOC estimation: The device addresses the problem of inaccurate SOC estimation by correcting the SOC using a corrector and updating the aging parameter of the electrochemical model.
- Voltage difference: The device reduces the voltage difference between the estimated voltage and the measured voltage of the battery, improving the accuracy of SOC estimation.
Benefits of this technology:
- Enhanced battery performance: Accurate SOC estimation allows for better battery management, leading to improved performance and longer battery life.
- Optimal energy utilization: Accurate SOC estimation enables efficient energy utilization in various applications, reducing waste and improving overall system efficiency.
- Cost savings: By accurately estimating the SOC and updating the aging parameter, the device can help prevent premature battery replacements, resulting in cost savings.
