Finally, we enter an era where EV battery degradation can be "diagnosed in 5 minutes."
Automatic degradation diagnosis line for EV batteries currently in use
Sixteen years have passed since the launch of the Nissan LEAF, and the demand for reuse and recycling of used EV batteries is expanding.
On the other hand, the condition and value of EV batteries rely on limited information such as appearance and mileage, making objective and quantitative evaluation difficult. This has presented challenges regarding distribution transparency and transaction efficiency.
Therefore, MIRAI-LABO has launched a service utilizing specialized technology that can diagnose the degradation level of EV batteries in a "short time and with high accuracy."
This is a service that has commercialized an innovative technology capable of performing degradation diagnosis, which conventionally took 48 hours, in 5 minutes, while keeping the error within ±5% of actual measured values.
Signs of a dramatic boom in the "Used EV Battery Market."
Market stakeholders who have actually used this service have provided feedback such as:
"In addition to the reduction in diagnosis time, I am surprised by the high accuracy," and "Being able to procure with guaranteed State of Health (SOH) accuracy holds great value for future procurement."
Furthermore, it is now possible to swiftly respond to needs such as, "Regardless of whether I buy or sell, I first want to accurately know the value of the batteries I own," and "I want to use the diagnosis only, without accompanying buying or selling." This leads to a higher level of sophistication in procurement decisions for used EV batteries.
From these voices as well, this service is expected to quickly resolve the information asymmetry in the used EV battery market, leading to a dramatic boom in the market.
"5-Minute EV Battery Degradation Diagnosis" is now highly acclaimed and accepting applications.
Applications for this service can be made at the "Energy Loop Terminal," a distribution platform for repurposed products utilizing used EV batteries, operated by Aucnet Inc.

MIRAI-LABO will continue to expand the functions and increase the utilization of battery trading services through its collaboration with Aucnet, while advancing EV battery diagnostic technology.
In addition, as an environmental platformer, we will continue to provide "GX design"—which utilizes environmental technologies and products to contribute to "clean energy," "decarbonization," and "effective use of resources"—while contributing to the realization of a circular society through the development of the "Energy Loop Terminal" as a foundation that comprehensively supports the reuse, repurposing, and recycling of EV batteries.
