Charging Method of Battery Pack, Management Method of Storage System, Management Apparatus of Battery Pack, Storage System, and Non-Transitory Storage Medium - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240097476 titled 'Charging Method of Battery Pack, Management Method of Storage System, Management Apparatus of Battery Pack, Storage System, and Non-Transitory Storage Medium
Simplified Explanation
The charging method described in the patent application involves initially charging a battery pack at a first rate until it reaches a reference voltage, then switching to a lower second charging rate until a specific electric charge amount is reached.
- Aqueous battery cells connected in series
- Constant-current charging at two different rates
- Charging until specific electric charge amount is reached
Potential Applications
This technology could be applied in electric vehicles, portable electronic devices, and renewable energy storage systems.
Problems Solved
This method helps prevent overcharging of battery packs, which can lead to reduced battery life and safety hazards.
Benefits
- Prolongs battery life - Enhances safety - Improves overall battery performance
Potential Commercial Applications
"Optimized Charging Method for Battery Packs in Series" could be used in electric vehicle manufacturing, consumer electronics companies, and energy storage system providers.
Possible Prior Art
One possible prior art is the use of pulse charging techniques in battery management systems to optimize charging efficiency and battery life.

Original Abstract Submitted
in one embodiment, there is provided a charging method of a battery pack in which a plurality of aqueous battery cells are electrically connected in series. in this charging method, in a case where the battery pack reaches a reference voltage by a constant-current charging at a first charging rate, constant-current charging is performed on the battery pack at the second charging rate lower than the first charging rate and being from 0.01 c or more to 0.05 c or less. then, this constant-current charging at the second charging rate is continued until a charged electric charge amount from a start timing of the constant-current charging at the second charging rate reaches a reference electric charge amount set from 1% or more to 5% or less of the nominal capacity of the battery pack.
