OCPP
Limits are sent to the charger over OCPP.

Every charge point gets its own limit
The plan only matters once it reaches the chargers. RiDERgy turns it into one limit per charge point, sends it automatically and replaces it with a new one every 15 minutes, always in the same order of priority.
From plan to charger
How a limit reaches a charge point
- 01
Plan
The plan decides which vehicle charges, how fast and when, against every fuse, price and departure.
- 02
One limit per charge point
The plan is split into a power limit for each charge point, so no fuse in the tree is exceeded.
- 03
Send
The limits are sent to the chargers automatically, with nothing to confirm by hand.
- 04
Check and repeat
Meter readings show what really happened, and the next plan starts from them.
The order of priority
Safety first, availability second, cost third
When the rules pull against each other, the first one wins.
- 01
Safety
No fuse is exceeded, on the grid connection or on any strand below it.
- 02
Availability
Every vehicle is ready at its departure time with the energy it needs.
- 03
Cost
Within the first two, charging moves to the cheapest quarter hours and keeps new peaks down.
How limits are sent
Through the systems you already run
No new hardware is the starting point. Which path is used depends on your setup.
Charger vendor cloud API
Where the charger vendor offers one, limits go through its cloud API.
Your charge point management system
Limits go through the system that already runs your chargers, connected as a service partner.
When something goes wrong
A lost signal never trips a fuse
- If a reading or a link is lost, charging carries on at a reduced limit until it comes back.
- Chargers keep the limit stored on the charger itself if new limits stop arriving.
- RiDERgy reads first and steers only after that, so control starts when the picture is complete.
Questions about control
Who decides when a vehicle charges?
The plan does, from your fuses, the tariff and the departure times. You set the targets, for example when a vehicle must be ready.
What if a vehicle needs to leave early?
A new departure time is picked up by the next plan, which is recalculated every 15 minutes.
Do I need to change my chargers?
No specific charger brand is needed. Limits go over OCPP, through the charger vendor's cloud API or through your charge point management system.
