Latest Patents

Isshiki’s listed patents address methods for detecting abnormalities and managing power storage blocks.

“Management device and power storage system” describes a device that monitors a module containing series-connected power storage blocks, each made up of parallel-connected cells. The device records block voltages over time, calculates voltage-drop rates, and identifies a potentially abnormal cell when a block’s rate differs sufficiently from the average or median rate of the other blocks.

A second patent with the same title concerns a power storage device made of series-connected blocks, each containing parallel-connected fuse-and-cell circuits. Its equalization controller balances the blocks when their voltage difference exceeds a set threshold. A fuse-blowout determination unit uses the frequency of equalization to assess whether a fuse has blown.

Career Highlights

The listed inventions demonstrate Isshiki’s work on battery monitoring, voltage balancing, and fault detection. These approaches are intended to help identify abnormal cells or blown fuses through measurements and system behavior.

Collaborations

Isshiki is associated with Panasonic Intellectual Property Management Co., Ltd. His listed coworkers include Noriharu Kobayashi and Hisashi Ono.

Conclusion

Yasumasa Isshiki’s patent work centers on practical techniques for monitoring power storage systems, balancing their components, and detecting potential faults.
