POWER STORAGE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18234934 titled 'POWER STORAGE SYSTEM

Simplified Explanation

The power storage system described in the patent application involves a control device that manages the charging of a plurality of assembled batteries. Specifically, when a predetermined time has passed since the last full charge of a particular battery, the control device charges that battery to full capacity and adjusts the storage amount of the other batteries in the system to ensure a predetermined total storage amount is reached after charging.

• Power storage system with power converter, assembled batteries, and control device
• Control device manages charging of batteries based on predetermined time intervals
• Charges specific battery to full capacity if time since last charge has elapsed
• Adjusts storage amount of other batteries to reach predetermined total storage amount after charging

Potential Applications

The technology described in this patent application could be applied in various industries and settings, including:

• Renewable energy storage systems
• Electric vehicles
• Backup power systems for homes and businesses

Problems Solved

This technology addresses several key issues in power storage systems, such as:

• Ensuring all batteries are fully charged and balanced

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

The patent application does not provide specific details on the algorithm or method used by the control device to adjust the storage amount of each battery to reach the predetermined total storage amount.

What safety features are implemented in the power storage system to prevent overcharging or overheating of the batteries?

The patent application does not mention any safety mechanisms or protocols that are in place to protect the batteries from potential risks during the charging process.

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.
