What Are The Network Connection Methods Of EV Charging Stations, And How To Ensure Network Security?

Solution 1: Each electric vehicle charging station is connected to Ethernet through RJ45 or optical fiber, connected to the charging station management center, and then connected to the Internet management center and database.
Solution 2: Each EV charging station directly accesses the Internet management center and database through wireless communication modules (such as GPRS, CDMA, 3G, 4G, etc.).
Solution 3: Each EV charging station forms a wireless sensor network through a ZigBee wireless communication module, connects a wired or wireless gateway device, and then accesses the Internet management center and database.
Different network connection methods have their own advantages and disadvantages, and you need to choose the appropriate solution according to the actual situation. To ensure cybersecurity, EV charging stations should take the following measures34:
Messages are encrypted and decrypted to ensure that adversaries cannot eavesdrop on the channel to ensure confidentiality.
Verify the integrity of key interaction information and support a trust model based on PKI certificate system.
Protect against common cyber threats such as replay attacks, denial-of-service attacks, malware attacks, and more.
Use IoT security products or similar solutions to encrypt data transmission, monitor the system process, network connection and port of electric vehicle charging stations, and block abnormal behavior.
