Overview of the ProCell EV Firewalls
ProCell’s EV Firewall 800 and 801 are designed to protect electric vehicle charging stations from cyber threats. As EVs become more popular, securing charging infrastructure is crucial. The firewalls provide a critical layer of protection by filtering incoming and outgoing network traffic.
Key Features
- ICS/SCADA-aware firewall optimized for EV sites
- Integrated intrusion prevention system (IPS)
- Extremely low power consumption
- Remote access via 4G/LTE cellular modem
- DIN rail mountable
Comparing the 800 and 801 Models
The 800 and 801 firewalls are very similar, with just a few key differences:
| Spec | Firewall 800 | Firewall 801 |
|---|---|---|
| Max Power (W) | 15 | 10 |
| Cellular Modem | Optional | Integrated 4G/LTE |
| Ports | 8 x Ethernet | 4 x Ethernet |
As seen in the table, the 801 model has an integrated cellular modem and lower power consumption at the cost of fewer Ethernet ports. The 800 is better suited for sites with wired internet while the 801 is optimized for remote sites relying on cellular.
Securing an EV Charging Station
Here is an example diagram showing how the firewall could be implemented at an EV charging station:
The firewall sits between the station’s internal network and external connections, filtering traffic in both directions. This prevents attackers from reaching critical charging systems.
The firewall can also connect to a remote management server via cellular modem. This enables monitoring of stations located anywhere while minimizing on-site IT infrastructure.
Frequently Asked Questions
What types of cyber threats do these firewalls protect against?
They defend against network-based attacks like malware, ransomware, denial of service, and intrusions. The IPS also blocks known vulnerabilities.
Do the firewalls require any on-site IT staff?
They are designed to run autonomously with remote management, although some user configuration is required during setup.
What networking protocols are supported?
These industrial firewalls support TCP/IP, UDP, ICMP, and other standard protocols. They also support common industrial protocols like Modbus TCP & RTU.
What kind of cellular connectivity does the 801 model support?
It has an integrated 4G/LTE modem that works with major US carriers. 5G options are coming soon.
Can the firewalls integrate with centralized management software?
Yes, they support REST APIs for integration with software like ProCell Insight or utility management systems.
This covers the key features and applications of the ProCell EV Firewall 800 and 801 models. Their specialized protections help mitigate risks for EV charging infrastructure. Let me know if you would like me to modify or expand this draft article in any way.
