Sharing of EV Battery Data Supported by METI

The Ministry of Economy, Trade and Industry says it will support the development of an industry-wide system for sharing information on the degradation status of EV batteries. Toyota and Honda will provide battery-related data to used car dealers, insurance companies and others. The aim is to prevent the export of used EVs overseas and enable the domestic utilization of batteries containing critical minerals.
Currently, battery degradation is difficult to assess, resulting in low trade-in prices for used EVs in the domestic market. The fact that approximately 80% were exported overseas was a cause for concern.
