CHARGE CONTROL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240332989 titled 'CHARGE CONTROL SYSTEM
Simplified Explanation: The patent application describes a charge control system that efficiently manages the charging of multiple batteries within a battery module to reduce costs.
- The system includes a charger, multiple Intelligent Power Units (IPUs), and a Controller Area Network (CAN) bus.
- Each IPU consists of a battery, a contactor, and a Battery Electronic Control Unit (ECU).
- The Battery ECU uses information from the CAN bus to control which battery receives power from the charger, ensuring only one battery is charged at a time.
- This sequential charging process optimizes the use of the charger and prevents simultaneous charging of multiple batteries.
Key Features and Innovation:
- Sequential charging of batteries within a battery module.
- Efficient use of the charger to reduce costs.
- Control system based on information from the CAN bus.
- Battery ECU manages power distribution to batteries via contactors.
- Prevents concurrent charging of multiple batteries.
Potential Applications: The technology can be applied in electric vehicles, energy storage systems, and other battery-powered devices where multiple batteries need to be charged efficiently.
Problems Solved:
- Cost reduction in battery module reuse.
- Efficient charging management for multiple batteries.
- Preventing overloading of the charger.
Benefits:
- Cost savings in battery module maintenance.
- Prolonged battery life due to optimized charging.
- Enhanced safety by preventing overcharging.
Commercial Applications: The technology can be utilized in electric vehicle manufacturing, renewable energy storage systems, and industrial equipment with battery modules to improve efficiency and reduce operational costs.
Prior Art: Prior research in battery management systems and charging control technologies can provide insights into similar approaches to sequential charging and power distribution in battery modules.
Frequently Updated Research: Stay updated on advancements in battery management systems, CAN bus technology, and energy storage solutions to enhance the efficiency and performance of the charge control system.
Questions about Charge Control System: 1. How does the Battery ECU determine which battery to charge based on the information from the CAN bus? 2. What are the potential challenges in implementing this charge control system in different types of battery modules?
Original Abstract Submitted
provided is a charge control system capable of reducing costs for reuse of a battery module. the charge control system includes a charger, a plurality of ipus, and a can bus, and each ipu includes a battery, a contactor, and a battery ecu. based on operation information provided via the can bus, the battery ecu causes the contactor of one ipu from among the plurality of ipus to provide power supply to the battery belonging to the one ipu and causes the contactor of a rest of the ipus to disconnect power supply to the battery belonging to the rest of the ipus, thereby performing control such that the charger charges the battery belonging to the one ipu without concurrently charging the battery belonging to the rest of the ipus.
