METHOD FOR CHARGING TRACTION BATTERY AND BATTERY MANAGEMENT SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18458164 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. The method includes obtaining the State of Health (SOH) of the battery and the State of Charge (SOC) during the charging process. It also determines an SOC interval value based on the SOH and controls the battery to discharge or stop being charged when the SOC changes by the interval value.

  • The method helps reduce the risk of lithium precipitation in the traction battery during the charging process.
  • It improves the safety performance of the traction battery by controlling the discharging or stopping of charging.
  • The battery management system can effectively monitor and manage the charging process of the traction battery.

Potential Applications

This technology can be applied in various industries and applications that use traction batteries, such as:

  • Electric vehicles (EVs) and hybrid electric vehicles (HEVs)
  • Electric bicycles and scooters
  • Renewable energy storage systems
  • Industrial equipment powered by batteries

Problems Solved

The technology addresses the following problems:

  • Risk of lithium precipitation: Lithium precipitation can occur during the charging process, leading to reduced battery performance and safety risks. This technology helps control the charging process to minimize this risk.
  • Safety concerns: By monitoring and controlling the discharging or stopping of charging, the technology improves the safety performance of the traction battery.
  • Battery degradation: The method considers the State of Health (SOH) of the battery, allowing for optimized charging and reducing battery degradation over time.

Benefits

The technology offers several benefits:

  • Enhanced safety: By controlling the discharging or stopping of charging, the risk of lithium precipitation and other safety concerns are reduced, improving the overall safety performance of the traction battery.
  • Extended battery lifespan: Optimized charging based on the battery's State of Health (SOH) helps minimize battery degradation, leading to a longer lifespan and improved overall performance.
  • Efficient battery management: The battery management system effectively monitors and manages the charging process, ensuring optimal utilization of the traction battery and maximizing its efficiency.


Original Abstract Submitted

Provided are a method for charging a traction battery and a battery management system. The method for charging the traction battery is applied to a battery management system, where the method includes: obtaining an SOH of the traction battery; in a charging process of the traction battery, obtaining an SOC of the traction battery; determining an SOC interval value corresponding to discharging or stopping being charged of the traction battery based on the SOH of the traction battery; and when the SOC of the traction battery changes by the SOC interval value, controlling the traction battery to discharge or stop being charged. Through the technical solution, in the charging process of the traction battery, the discharging or the stopping being charged of the traction battery can be controlled to reduce the risk of lithium precipitation in the traction battery and improve the safety performance of the traction battery.
