01 / MONITORING

Charging bay monitoring

Overhead cameras monitor vehicle occupancy and conditions in the charging area. View bay status and event history in the monitoring dashboard.

02 / ALERT

Incident alerts

Alert managers to abnormal conditions, including suspected fire. Location and on-site information help them assess the situation and decide how to respond.

03 / CONTROL

On-site response integration

The cabinet-mounted edge device supports charging station power shutdown and integration with fire protection systems. Monitoring and control are configured for each site.

Development concept showing underbody sensing and temperature distribution

Vehicle localization
Underbody thermal monitoring

We are developing AI-based vehicle localization and monitoring of temperature changes beneath vehicles, bringing spatial and thermal information together across charging bays.
