The investigation has now shifted from the battery maker to the manufacturer of the system that monitors the battery's voltage and temperature, Ishii said.
However, it's the future uses we're more excited about -- eventually, you'll be able to upload energy usage data into the system automatically, provided you're getting voltage from one of the partner companies.
For example, in large hotels, voltage dips and power interruptions of less than a second can result in booking and reservation system failures, which are extremely expensive.
