The CCS2 DC charging gun cable harness is designed to flexibly adapt to charging requirements across different power levels. Integrated with a multi-level intelligent protection system, it continuously monitors current, voltage, and temperature parameters. Upon detecting overcurrent, overvoltage, or abnormal temperature conditions, it activates a millisecond-level automatic power cutoff mechanism to effectively prevent battery overload and damage to vehicle electrical systems. Through its integrated safety solutions, this harness enhances charging efficiency while establishing end-to-end security across hardware and control systems for new energy vehicles, ensuring safe and reliable charging operations.
