Question 1

What is the primary role of a VPN in an EVSE network architecture?

Accepted Answer

Provide secure encrypted communication between EVSE and back-end systems

Answer

A VPN creates an encrypted tunnel between the EVSE and back-end systems, protecting sensitive data from interception on public or cellular networks.

Question 2

Which network protocol automatically assigns IP addresses to EVSE units on a network?

Accepted Answer

DHCP

Answer

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to networked devices, including EVSE, eliminating the need for manual static configuration.

Question 3

In the context of EV charging networks, what does 'roaming' mean?

Accepted Answer

Using a charging station from one network while authenticated through another

Answer

Roaming allows an EV driver to charge at a station operated by a different network than the one they subscribed to, similar to cellular phone roaming between carriers.

Question 4

The OCPI (Open Charge Point Interface) protocol is primarily designed for:

Accepted Answer

Enabling roaming between different EV charging networks

Answer

OCPI is an open protocol that enables different EV charging networks to share data and allow driver roaming, so users can charge across multiple network operators.

Question 5

What cybersecurity practice is most essential for protecting EVSE data transmitted over public networks?

Accepted Answer

TLS/SSL encryption for all communications

Answer

TLS/SSL encryption secures data in transit between EVSE and central systems, preventing eavesdropping or man-in-the-middle attacks on public and cellular networks.
