What is EV charging cybersecurity?
EV charging cybersecurity involves protecting charging stations, management software, communications and associated data against unauthorised access and cyber threats.
As charging infrastructure becomes more connected, security must be considered across both the physical equipment and the systems used to manage it.
What are the main risks?
Potential risks include unauthorised access to management systems, compromised user accounts, insecure communications, outdated software and exposure of sensitive operational data.
The impact depends on the system. An incident could affect charging availability, data confidentiality or the operation of connected infrastructure.
How can businesses improve security?
Use strong authentication: Apply appropriate access controls and multi-factor authentication where supported.
Keep systems updated: Maintain charger firmware, software and connected components in line with vendor guidance.
Secure communications: Confirm that devices use appropriate security measures when exchanging information with management systems.
Limit access: Give users and administrators only the permissions they need.
Plan for incidents: Establish procedures for reporting, investigating and responding to security events.
Assess suppliers: Ask providers about security practices, vulnerability handling, updates and support responsibilities.
Why does interoperability matter for security?
Protocols such as OCPP help standardise communication between chargers and management systems. However, protocol support alone does not guarantee that a deployment is secure.
Security also depends on implementation, configuration, identity management, network design and ongoing maintenance.
Electric Miles develops EV charging and energy-management software. Businesses evaluating connected charging solutions should ask providers how security is handled across the specific products and integrations they plan to use.

Frequently asked questions
Can EV chargers be hacked?
Connected chargers may be exposed to cyber threats if vulnerabilities or poor security practices exist. Risk varies by device and deployment.
Is OCPP enough to secure an EV charging network?
No. A secure deployment also requires appropriate configuration, access controls, updates and operational security practices.
