The lab designs social systems such as electric power and logistics based on the concept of distributed coordination.
AboutAbout the lab
Solving challenges in electric power, logistics, and retail
Tanaka Lab conducts research to solve challenges in a variety of industries, including electric power, logistics, and retail.
The lab works on blockchain-based systems for power distribution and settlement, as well as methods for managing logistics and electric power based on supply forecasts.
The lab also has research that uses power supply data to avoid failed deliveries when recipients are not at home.
The lab is also advancing joint research with companies.

- A mechanism in which users interact directly with one another without going through a central administrator
- Distributed resources
- Equipment and resources owned individually in many different places, such as home storage batteries and electric vehicles
- Secondary battery
- A battery that can be recharged and used repeatedly, such as a lithium-ion battery

ResearchResearch themes
The lab conducts research to solve challenges in a variety of industries, including electric power, logistics, and retail. It works on building mechanisms that guide distributed resources on the user side, such as storage batteries and electric vehicles, to coordinate with one another as a whole.
*Illustrative imageP2P Power Sharing
This is research on P2P power sharing using blockchain technology. In field trials with Toyota Motor Corporation and others, the lab tested a mechanism in which electric vehicles and other devices absorb surplus daytime electricity.
*Illustrative imageDesign of Distributed and Coordinated Systems
As IoT devices and other equipment increasingly operate autonomously, the lab studies how to guide scattered distributed resources to coordinate with one another and incorporate this into system design.
*Illustrative imageEvaluating the Performance of Used Batteries
The lab is building models that evaluate how much performance a battery has retained. It has developed evaluation methods that use vehicle usage history, small-scale charge-discharge tests, and simulation.
*Illustrative imageReuse of Secondary Batteries
The lab examines a lifecycle in which electric vehicle batteries are reused as stationary batteries in buildings and homes even after the vehicle is scrapped. It has also devised a mechanism that lets users use batteries without bearing the asset risk of the battery.
