METHOD FOR CHARGING TRACTION BATTERY AND BATTERY MANAGEMENT SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18458168 titled 'METHOD FOR CHARGING TRACTION BATTERY AND BATTERY MANAGEMENT SYSTEM
Simplified Explanation
The patent application describes a method for charging a traction battery and a battery management system that can enhance the performance of the battery. Here are the key points:
- The method is applied to a battery management system (BMS) of a traction battery.
- During the charging process, the BMS obtains various state parameters of the battery, such as state of charge (SOC), state of health (SOH), and temperature.
- Based on these state parameters, the BMS determines an SOC interval value and a discharging parameter for discharging the battery.
- The discharging parameter includes parameters like discharging time, discharging current, and discharging waveform.
Potential applications of this technology:
- Electric vehicles: The method can be used to optimize the charging and discharging of traction batteries in electric vehicles, improving their overall performance and efficiency.
- Renewable energy storage: The method can be applied to battery systems used for storing energy from renewable sources, ensuring optimal charging and discharging for maximum efficiency.
Problems solved by this technology:
- Inefficient charging: The method addresses the issue of inefficient charging by considering various state parameters of the battery and determining the optimal charging strategy.
- Battery degradation: By monitoring the state of health (SOH) parameter, the method helps prevent excessive battery degradation by optimizing the discharging process.
Benefits of this technology:
- Improved battery performance: The method enhances the performance of the traction battery by optimizing the charging and discharging processes based on the battery's state parameters.
- Extended battery lifespan: By considering the state of health (SOH) parameter, the method helps prolong the lifespan of the battery by preventing excessive degradation.
- Enhanced energy efficiency: The optimized charging and discharging processes result in improved energy efficiency, leading to better overall performance and reduced energy consumption.
