Reliability and Safety
Designed to Fail Safe
SmartCharge is built so the charging limits you set keep holding, even when the network, the cloud, or a charger misbehaves.
Limits That Hold at the Charger
Site protection should not depend on a connection to the cloud. SmartCharge keeps the safety envelope on the chargers themselves.
A safe default on every charger
Each managed charger holds a default share sized so the site stays within its limits even if every stall draws at once.
Extra power expires on its own
Power above the safe share is a short lease. If the cloud or the network goes away, the charger falls back to its safe share by itself.
Grid events held locally
Firm demand-response events for the next 24 hours are written into the chargers' own profiles, so they hold through an outage.
Reboots handled
After a charger restarts, its safe profiles are reinstalled and checked against what the charger reports it is enforcing.
Every Decision Checked
Load management is a control system with physical consequences, so every step is checked.
An independent verifier
Every plan is checked per node and per phase at every step, including the case where every idle stall starts at once. If it fails, nothing is sent.
Actual draw against the plan
Metered power is compared with each allocation. A charger that keeps drawing more is flagged, planned around, and raises an alert.
Offline means reserved
An offline charger keeps its committed power reserved, and one never seen keeping its profiles across a reboot is counted at its full rating.
No silent failures
Reductions are sent before increases, and a command for an offline charger, or one that has expired, is refused with a reason instead of dropped.
A record of every decision
Each allocation is kept for 30 days with its trigger, the verifier result, and every charger's answer.
Secure charger connections
OCPP security profiles 1 to 3: password authentication, TLS, and client certificates.
How We Test It
Before load management reaches a real depot, it has to pass on a simulated one.
Real protocols, simulated chargers
A charger simulator runs OCPP 1.6 and 2.0.1 stations, AC and DC, in a mixed depot.
Faults on purpose
Chargers that reject or ignore profiles, lose them on reboot, drift in time, answer slowly, drop the connection, or lose power.
An oracle that watches the limits
Every run is checked for five kinds of limit violation, including after every lease has expired.
Behavior that does not drift
A frozen set of cases proves load management behaves the same when cost optimization is turned off.
Built for teams
Organizations with roles for owners, admins, managers, fleet admins, depot managers, dispatchers, finance (read only) and drivers. Depot groups roll up reports by region or district. Accounts are protected by a strong password policy, email-confirmed changes, and a device list you can sign out remotely.
Safety first, then savings.
