BATTERY MANAGEMENT SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18363511 titled 'BATTERY MANAGEMENT SYSTEM
Simplified Explanation
The patent application describes a battery management system that aims to minimize the deterioration of secondary batteries used in devices. The system includes several units to acquire usage history information, estimate deterioration state and factor, acquire battery load information, and identify the degree of deterioration change. The battery management unit then uses this information to associate batteries with future use modes, ensuring the evaluation value of the battery's deterioration becomes a minimum value.
- The battery management system aims to minimize the deterioration of secondary batteries.
- Usage history information is acquired to estimate the current deterioration state and factor of the battery.
- Battery load information is obtained to indicate the future battery load.
- The system identifies the degree of deterioration change using the current deterioration state, factor, and battery load information.
- The battery management unit associates batteries with future use modes based on the deterioration change degree, minimizing the evaluation value of the battery's deterioration.
Potential Applications
- Battery management systems for various electronic devices.
- Electric vehicles and hybrid vehicles.
- Renewable energy storage systems.
Problems Solved
- Minimizing battery deterioration to prolong battery lifespan.
- Optimizing battery usage based on future load requirements.
- Improving overall battery management efficiency.
Benefits
- Prolongs battery lifespan and reduces the need for frequent battery replacements.
- Enhances the performance and reliability of devices using secondary batteries.
- Optimizes battery usage, leading to improved energy efficiency.
Original Abstract Submitted
A battery management system includes a usage history acquisition unit, a deterioration estimation unit, a battery load acquisition unit, a deterioration change degree identification unit, and a battery management unit. The usage history acquisition unit acquires usage history information. The deterioration estimation unit estimates a current deterioration state and a deterioration factor of the secondary battery based on the usage history information. The battery load acquisition unit acquires battery load information indicating a future battery load. The deterioration change degree identification unit identifies a deterioration change degree by using the current deterioration state, the deterioration factor and the battery load information of the secondary battery. The battery management unit uses the deterioration change degree to associate secondary batteries with future use modes so that an evaluation value indicating a degree of deterioration of the secondary battery in use devices becomes a minimum value.
