ISO 15118-20:2025: The Future of Wireless EV Charging Standards

Introduction

The EV charging landscape is evolving rapidly, and with it, the standards that govern interoperability and security. 2025 marks a significant milestone with the publication of ISO 15118-20:2025, introducing comprehensive standards for wireless power transfer in electric vehicles. For charge point operators (CPOs) and e-mobility service providers (eMSPs), understanding these updates is crucial for future-proofing infrastructure investments.

Key Updates in ISO 15118 for 2025

1. ISO 15118-20: Wireless Charging Standardization

The newly published ISO 15118-20:2025 standard establishes the foundation for wireless EV charging systems. This comprehensive standard covers:

Alignment procedures ensuring optimal positioning between vehicle and charging pad
Power control mechanisms for efficient energy transfer
Safety requirements specific to wireless charging environments
Communication protocols for seamless vehicle-charger interaction

For CPOs deploying next-generation charging infrastructure, this standard eliminates vendor lock-in and ensures compatibility across different wireless charging solutions.

2. Enhanced Cybersecurity Requirements

With the increasing sophistication of cyber threats, the 2025 updates introduce robust security measures:

End-to-end encryption for all charging communication
Multi-factor authentication for administrative access
Secure firmware updates with cryptographic verification
Intrusion detection systems integrated into charging station management

Our OCPP central system already incorporates these security enhancements, providing CPOs with a secure foundation for their charging networks.

3. Expanded V2G/V2H Capabilities

The standards now include comprehensive support for:

Bidirectional charging protocols enabling vehicle-to-grid and vehicle-to-home applications
Dynamic power negotiation based on grid conditions and pricing signals
Aggregated V2G management for fleet operators and energy service providers
Standardized payment settlement for energy discharged back to the grid

4. Improved Plug and Charge Authentication

Building on the existing Plug and Charge functionality, the 2025 updates deliver:

Digital certificate management following ISO 15118-2 specifications
Cross-border interoperability for international charging networks
Roth certificates enabling roaming agreements between eMSPs
Automated contract negotiation between vehicles and charging stations
