APPARATUS AND METHOD FOR BALANCING BATTERIES CONNECTED IN PARALLEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 17884296 titled 'APPARATUS AND METHOD FOR BALANCING BATTERIES CONNECTED IN PARALLEL
Simplified Explanation
The patent application describes an apparatus and method for balancing batteries connected in parallel. The system collects the States Of Charge (SOCs) of multiple battery packs and determines if they need to enter a balancing mode. It then determines a balancing control mode based on the vehicle state and controls the relay of the battery packs to perform charging or discharging and balance the charge between them.
- The apparatus collects the States Of Charge (SOCs) of multiple battery packs.
- It determines if the battery packs need to enter a balancing mode based on their collected SOCs.
- The system determines a balancing control mode based on the vehicle state.
- When the battery packs enter the balancing mode, the system controls the relay of the battery packs.
- The system performs charging or discharging and balances the charge between the battery packs.
Potential Applications
This technology can be applied in various industries and applications, including:
- Electric vehicles: Balancing the charge between battery packs in electric vehicles to optimize performance and extend battery life.
- Renewable energy systems: Balancing the charge between battery packs in solar or wind energy systems to ensure efficient energy storage and utilization.
- Portable electronics: Balancing the charge between battery packs in smartphones, laptops, and other portable devices to improve battery life and performance.
Problems Solved
The technology addresses several problems related to battery packs connected in parallel:
- Imbalanced charge: It solves the issue of uneven charge distribution among battery packs, which can lead to reduced overall capacity and performance.
- Battery degradation: By balancing the charge between battery packs, it helps prevent overcharging or undercharging, which can cause premature battery degradation.
- Inefficient energy utilization: Balancing the charge ensures that all battery packs are utilized optimally, maximizing the overall energy storage and utilization efficiency.
Benefits
The technology offers several benefits:
- Improved battery performance: Balancing the charge between battery packs ensures that each pack operates at its optimal level, enhancing overall battery performance.
- Extended battery life: By preventing overcharging or undercharging, the technology helps prolong the lifespan of battery packs, reducing the need for frequent replacements.
- Enhanced energy efficiency: Balancing the charge between battery packs maximizes energy storage and utilization efficiency, resulting in improved overall system efficiency.
Original Abstract Submitted
An apparatus and a method for balancing batteries connected in parallel are provided. The apparatus collects States Of Charge (SOCs) of at least two or more battery packs, determines whether the at least two or more battery packs enter a balancing mode based on the collected SOCs of the at least two or more battery packs, determines a balancing control mode based on a vehicle state, when it is determined that the at least two or more battery packs enter the balancing mode, and controls a relay of at least one of the at least two or more battery packs depending on the determined balancing control mode to perform charging or discharging and performs balancing between the at least two or more battery packs.
