Powering Up Securely: Enabling Resilient Communications for EV Charging Networks

The Challenge

The rapidly expanding Electric Vehicle (EV) charging infrastructure is a critical component of the automotive future, demanding highly reliable and secure communications. Personnel responsible for installation, maintenance, and fault resolution often operate remotely, managing complex electrical systems and interacting with the public. Their communication needs include remote diagnostics, coordination with grid operators, support for end-users, and rapid response to emergencies. Unsecured or unreliable mobile communications in this sector can lead to operational failures, safety hazards, and significant public inconvenience, undermining confidence in EV adoption.

Business Impact

Grid Instability and Downtime

Delayed communication regarding charger faults or grid fluctuations can impact the stability of the charging network, leading to outages and frustrated EV owners unable to charge their vehicles.

Safety Risks

Working with high-voltage EV charging equipment requires immediate and reliable communication for safety protocols and emergency response. Poor communication puts technicians at heightened risk, especially in remote or isolated locations.

Eroded Public Trust and Adoption

Frequent charging station failures or unresponsive support due to communication breakdowns can deter EV adoption, as consumers demand dependable infrastructure to support their vehicles.

How Tango Extend Solves This

Tango Extend provides a secure and resilient mobile communication platform essential for the management and maintenance of EV charging infrastructure. By integrating mobile voice and data into a secure enterprise UC environment (Microsoft Teams or Cisco Webex Calling), it ensures that all personnel have reliable, trackable, and secure communication channels, critical for operational continuity, safety, and rapid incident response.

• Secure Mobile Connectivity — Ensure all communications related to critical infrastructure are secure, encrypted, and compliant with industry standards, preventing unauthorised access or interception.
• Rapid Incident Response — Facilitate immediate voice and team collaboration for troubleshooting and emergency response, minimising downtime and ensuring public safety.
• Centralised Communication Records — All mobile interactions are captured and archived, providing an auditable trail for regulatory compliance, fault analysis, and operational improvements.

Use Case

An EV charging station experiences a power fault in a rural area. The on-call technician receives an automated alert and uses their Tango Extend-enabled mobile to contact the network operations centre immediately via their business line. Through a Teams call, they initiate diagnostic checks collaboratively with a remote engineer. The call is recorded for future analysis. If a physical repair is needed, the technician can securely coordinate with local power utility teams, ensuring efficient and safe resolution, and restoring public charging services quickly.

FAQs

Q? How does Tango Extend ensure the security of communications for EV charging infrastructure?

A. By routing all mobile business calls and data through the corporate UC framework, Tango Extend leverages enterprise-grade security protocols, encryption, and access controls inherent in platforms like Microsoft Teams or Cisco Webex Calling. This ensures that sensitive operational communications are protected from external threats and comply with data privacy regulations.

Q? Can Tango Extend help manage unexpected surges in EV charging demand?

A. While Tango Extend's primary function is secure communication, improved communication channels enable faster coordination between charging network operators and grid managers, facilitating real-time decision-making to manage demand fluctuations, troubleshoot issues, and ensure system stability more effectively.
