AI Technical Summary
Existing safety protection solutions for high-power DC charging suffer from high false alarm rates, high missed detection rates, and an inability to achieve precise identification and timely control of safety status during the charging process. In particular, they struggle to balance safety and efficiency under complex operating conditions.
By collecting multi-source operational data in real time, performing preprocessing and feature extraction, dynamic safety thresholds are generated. Based on the comparison between multi-dimensional operational characteristics and dynamic safety thresholds, risk levels are identified and prevention and control instructions are generated, thereby realizing dynamic risk assessment and proactive prevention and control of the charging process.
It reduced the false alarm rate and the missed detection rate, improved the overall safety and operational reliability of the charging system, and protected the interests of users and operators.
