EV charging features guide: schedules, tariffs, load management and vehicle response
A practical guide to the charger-side features that make everyday charging easier to understand

EV charging features are most useful when they explain what is happening, not just when they add another setting to the app.
For many customers, the important questions are simple. Why has charging not started yet? Is the charger waiting for a schedule? Is the vehicle asking for energy? Has the site supply changed? Is this expected behaviour, or does someone need to look at it?
This guide explains four charging feature areas that matter in everyday PlugStream use: scheduled charging, smart tariff charging, load management and vehicle response.
Quick answer: what are EV charging features?
EV charging features are charger-side, app-side and support-side tools that help a charging session start, pause, continue or explain itself more clearly. They do not replace the vehicle, electrical supply or customer settings. They help the charger make better decisions and give customers a clearer route to the next step.
For PlugStream, the strongest feature set is the one that helps a customer understand the whole charging journey:
| Charging moment | Common question | Useful guide |
|---|---|---|
| Saved charging window | Why has charging not started? | Scheduled EV charging not starting |
| Off-peak charging | How does tariff-aware charging work? | Smart tariff EV charging |
| Site power changes | Why has charging slowed or paused? | EV charger load management |
| Vehicle handover | What does waiting for vehicle mean? | Waiting for vehicle |
Scheduled charging: plug in now, charge later
Scheduled charging lets a driver plug in before the charger is meant to start delivering energy. That delay might be based on a saved schedule, an off-peak window, a vehicle departure plan or an app-led charging mode.
The important point is that waiting can be correct. If the charger is waiting for the planned window, an immediate lack of energy flow does not automatically mean the charger is faulty.
When a scheduled session does not start as expected, the first checks are usually:
- the saved charger schedule
- the vehicle's own charging limit or departure schedule
- whether the charger is online
- whether the cable is fully connected
- whether the charger is waiting for the vehicle, site telemetry or available supply

Smart tariff charging: align charging with cheaper windows
Smart tariff charging is about timing. The customer wants the vehicle to charge during a preferred or cheaper window where their energy plan supports it.
The tariff is not controlled by the charger. The charger follows the schedule or smart charging instruction it has been given. The vehicle still decides whether it will accept energy when the charger offers it.
That is why tariff-aware charging benefits from clear status messages. A customer should be able to tell whether charging is waiting for the right time, waiting for the vehicle, paused by a site condition or offline.

Load management: protect the wider site
Load management helps the charger work around the available electrical capacity at the property or site.
If the home or site is using more power elsewhere, the charger may reduce output or pause charging until there is enough capacity again. In a commercial setting, load management can also help several bays share available supply more carefully.
That behaviour can look confusing if it is only shown as "not charging". It is much clearer when the charger can explain that charging is paused or limited because of site conditions.

Vehicle response: the charger cannot do everything
The charger can offer energy and follow the charging instruction. The vehicle decides whether to accept energy.
If a charger shows a waiting-for-vehicle type state, that usually means the charger is ready but the vehicle is not requesting energy at that moment. The reason could be a battery limit, vehicle schedule, sleep behaviour, cable state or vehicle-side setting.
Vehicle Wake Assist helps PlugStream handle some delayed-start handovers more gracefully where the charger and vehicle support it. It does not guarantee that every vehicle sleep state can be overridden.

How these features work together
The charging journey is a sequence, not a single on/off state.
- The driver plugs in.
- The charger checks its mode, schedule and connection state.
- The charger waits if the planned window has not opened.
- The charger offers energy when charging should begin.
- The vehicle decides whether to accept energy.
- Load management can adjust output if site conditions change.
- The app and support team need a clear status if charging does not happen as expected.
Charger Readiness helps make that journey easier to understand by surfacing charger-side signals before the next charging window. Vehicle Wake Assist focuses on the delayed-start handover when the charger is ready but the vehicle may not respond as expected.

Charging features questions
Do charging features guarantee every session will start?
No. Charging still depends on the charger, vehicle, cable, supply, settings and connectivity. Good charging features reduce uncertainty and help guide the next step.
Is delayed charging the same as a charger fault?
No. A charger can be waiting correctly for a saved schedule, smart charging window, vehicle response or site power condition.
Why does PlugStream write about these features together?
Customers usually experience these features together. A missed charging window might involve a schedule, vehicle sleep state and load-management signal, so the most useful guidance explains the whole journey.
