==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 18175616 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 abstract describes a charging method for a battery pack with multiple aqueous battery cells connected in series. The method involves initially charging the battery pack at a first rate until it reaches a reference voltage, then switching to a lower second charging rate for continued charging until a specific electric charge amount is reached.

* Explanation of the patent/innovation:
- Charging method for a battery pack with multiple aqueous battery cells connected in series
- Initial constant-current charging at a first rate until reference voltage is reached
- Switching to a lower second charging rate (0.01C to 0.05C) for continued charging
- Continued charging at the second rate until a specific electric charge amount is reached (1% to 5% of nominal capacity)

Potential applications of this technology:
- Electric vehicles
- Energy storage systems
- Portable electronic devices

Problems solved by this technology:
- Efficient and safe charging of battery packs with multiple cells
- Preventing overcharging and damage to battery cells

Benefits of this technology:
- Prolongs battery pack lifespan
- Improves charging efficiency
- Enhances overall battery performance

Potential commercial applications of this technology:
- Battery manufacturing companies
- Electric vehicle manufacturers
- Energy storage system providers

Possible prior art:
- Similar charging methods for battery packs with multiple cells
- Research on optimizing charging rates for battery packs

Unanswered questions:
1. How does this charging method compare to existing methods in terms of charging efficiency and battery lifespan?
2. Are there any specific safety features incorporated into this charging method to prevent overheating or overcharging of the battery pack?


==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.
