Hongfa solutions for electric vehicles

Overcurrent / Short Circuit Protection

• MCB/RCBO
• Limits energy as low as 75kA²s
• Surge Current Requirement very low
• High temp threshold

Automatic reclosing of supply possibilities:

• Car needs to be disconnected before switching back on (Wallbox to verify over PP)
• Reclosing Device needs to measure fault free state (ARD acc. e.g.: IEC/EN 63024)
• Some countries prohibit automatic reclosing

Switching Devices:

• Contactor with specs according to IEC/EN 61851-1 and IEC/EN 62955
• Relay with specs according to IEC/EN 61851-1 and IEC/EN 62955

RDC-DD:

• Product standard IEC/EN 62955
• Detecting DC fault currents (limit of 6mA DC)
• Switching of in a timely manner
• Safely switching of (requirements for endurance and fault conditions)

Signal Control and I/O:

• Signal control to internal control boards
• I/O control
• Directly operated by µC
