BATTERY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240322270 titled 'BATTERY SYSTEM
The patent application describes a battery system with multiple battery packs, each containing several battery cells. These packs are managed by slave Battery Management Systems (BMSs), each equipped with a Battery Monitoring Integrated Circuit (BMIC) and a relay that activates when the BMIC is operational.
- The system includes multiple resistors connected to a power source, with a Master BMS determining the positions and number of operating BMICs based on the sensing voltage obtained by dividing the power source voltage by these resistors.
- The innovation allows for efficient monitoring and management of battery packs within the system, optimizing performance and safety.
- By accurately determining the operating BMICs, the system can effectively distribute the monitoring workload and ensure balanced operation of the battery packs.
- The use of resistors in the system helps in accurately sensing the voltage levels and determining the status of the battery packs.
- Overall, this technology enhances the reliability and efficiency of battery systems, particularly in applications where multiple battery packs need to be monitored and managed simultaneously.
Potential Applications: - Electric vehicles - Energy storage systems - Portable electronics
Problems Solved: - Efficient monitoring of multiple battery packs - Balancing workload among Battery Management Systems - Accurate voltage sensing for improved performance
Benefits: - Enhanced safety - Improved battery pack performance - Optimal management of battery systems
Commercial Applications: Title: Advanced Battery Management System for Enhanced Performance in Electric Vehicles This technology can be applied in electric vehicles to improve battery efficiency and overall performance, leading to longer battery life and increased reliability. The market implications include a potential increase in the adoption of electric vehicles due to improved battery management capabilities.
Questions about Battery Management Systems: 1. How does the use of resistors help in determining the operating BMICs in the battery system? 2. What are the key benefits of accurately monitoring and managing multiple battery packs in a system?
