Interoperability and Open Standards
Built on the Standards Chargers and Vehicles Already Speak
SmartCharge uses open protocols end to end, so you can choose chargers, vehicles and partners on their merits.
Four Open Standards
Each one covers a different link in the chain, from the grid to the vehicle.
OCPP, Done Carefully
Smart charging only works if chargers receive exactly what the specification expects.
Two versions, one platform
Chargers on OCPP 1.6 and OCPP 2.0.1 run side by side, AC and DC, from different vendors.
Smart charging profiles
Station maximum, default and transaction profiles, sent the way the specification defines for each version.
Checked before it is sent
Every outgoing smart-charging request is validated against the specification. A request that does not conform is refused, not sent.
Capability discovery
SmartCharge asks each charger which units and how many schedule periods it supports, and plans within them.
Firmware and events
Firmware updates with status reporting, plus fault and security events from the charger.
No silent failures
A command for an offline charger, or one that has expired, is refused with a reason instead of being dropped.
Vehicles and Security
ISO 15118 for the vehicle, and the OCPP security profiles for the charger.
Plug and Charge for fleet vehicles
Enrolled fleet vehicles authenticate over the cable with an ISO 15118-2 contract certificate, with SmartCharge as the contract provider, over OCPP 2.0.1.
Departure times from the vehicle
Where the vehicle supports ISO 15118, it reports when it needs to leave, and SmartCharge plans charging around it.
Charger security profiles 1 to 3
Chargers can connect with password authentication, over TLS, and with client certificates, following the OCPP security profiles.
Open standards, so you are never locked in.
Tell us which chargers and vehicles you run, and we will show you how SmartCharge works with them.
