POWER STORAGE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240128766 titled 'POWER STORAGE SYSTEM

Simplified Explanation

The power storage system described in the patent application includes a power converter, a plurality of assembled batteries, and a control device. The control device is responsible for managing the charging of the batteries to ensure optimal performance and longevity. Here are some key points to note about the innovation:

• The control device charges the first assembled battery when a predetermined time has elapsed since the previous full charge of the batteries.
• The control device adjusts the storage amount of the second assembled battery to maintain a predetermined total storage amount for all batteries after charging.

Potential Applications

The technology described in this patent application could be applied in various industries where efficient power storage systems are needed, such as renewable energy storage, electric vehicles, and backup power systems.

Problems Solved

This technology addresses the issue of uneven charging and storage capacity among batteries in a system, ensuring that all batteries are charged optimally and contribute equally to the overall storage capacity.

Benefits

The benefits of this technology include improved battery performance, extended battery life, and increased overall system efficiency. By managing the charging and storage of batteries effectively, the system can operate more reliably and sustainably.

Potential Commercial Applications

Potential commercial applications of this technology include energy storage systems for residential and commercial buildings, electric vehicle charging stations, and off-grid power systems. The optimized battery management system could attract interest from companies looking to improve the efficiency and reliability of their power storage solutions.

Possible Prior Art

One possible prior art in this field is the use of battery management systems in electric vehicles to monitor and control the charging and discharging of individual battery cells. These systems help optimize battery performance and extend the overall lifespan of the battery pack.

How does the control device determine the optimal storage amount for each battery after charging?

The control device likely uses algorithms and sensors to monitor the charging status and storage capacity of each battery, adjusting the storage amount of the second assembled battery accordingly.

What happens if one of the assembled batteries fails or malfunctions during the charging process?

In the event of a battery failure or malfunction, the control device may have built-in safety mechanisms to isolate the faulty battery and prevent damage to the rest of the system. Additionally, the system may have diagnostic capabilities to identify and address the issue promptly.

Original Abstract Submitted

the power storage system includes a power converter, a plurality of assembled batteries, and a control device. when there is a first assembled battery in which a predetermined time has elapsed since the previous full charge of the plurality of assembled batteries when each of the assembled batteries is charged, the control device charges the first assembled battery until the full charge, and adjusts the storage amount of the second assembled battery other than the first assembled battery in the plurality of assembled batteries so that the sum of the storage amounts after the charge of each of the assembled batteries becomes a predetermined amount.
