Technical specifications

Take a deeper look at the tech behind Josev

ISO 15118 and Plug & Charge bring an elevated experience to both network operators and EV drivers
ISO 15118-2

Enables the most user-friendly and secure charging experience for both AC and DC chargers.

ISO 15118-3

Establishes the data link between EV and charger via the charging cable (through PLC via on HomePlug Green PHY).

ISO 15118-20

Second generation ISO 15118, enables vehicle-to-grid, wireless charging, ACD-P , higher data security, and more.

DIN SPEC 70121

Most CCS vehicles still support DIN SPEC 70121 for DC charging - and so does Josev, to help transition to ISO 15118.

Shedding light on the EV-to-charger conversation

For network operators (CPOs), the digital conversation between EVs and chargers has been like a black box - until now. A charging station running on Josev and managed by the Switch platform unveils the ISO 15118 conversation to the CPO. This helps debugging any potential issues that may arise during an ISO 15118 charging session and helps the CPO to keep on top of their game.

Core [Certified]

Josev is certified by the OCA for OCPP 2.0.1 Core use cases. This means Josev stations work seamlessly with any 2.0.1 CSMS for complete remote operation and control.

Advanced Security [Certified]

Mutual TLS authentication and encrypted communication make OCPP 2.0.1 stations the most secure in the world, protecting charging stations, vehicles, the grid, and customers.

Advanced Diagnostics

Stations auto-report their hardware and configuration to the backend for easy diagnosis of charger faults. Faults are automatically reported to operators reducing maintenance costs and increasing uptime.
