AIS 230 and the Security of EV Charging Interfaces

A charging session is a communication session. The vehicle and the supply equipment negotiate parameters, exchange identifiers and, in some deployments, authorise payment. Each of those is an interface an attacker can reach without touching the vehicle’s interior.

Why charging deserves its own analysis

• The counterparty is infrastructure you do not own and cannot patch
• Physical access to public charging equipment is trivially available to an attacker
• Charging communication reaches systems with real energy-domain consequences
• Identity and billing data may traverse the same interface

Fitting charging into your CSMS

Charging interfaces belong in the same item definitions, TARAs and monitoring processes as the rest of the vehicle. Organisations that treat charging as an energy-team concern rather than a cybersecurity item end up with an unassessed interface at type approval.

Scope and applicability are defined through the Indian regulatory process and continue to evolve alongside charging infrastructure standards. Verify current requirements directly.
