Off-peak saving is decided by the clock, not the charger: the same kilowatt-hour costs less inside your tariff’s cheap window. With the EV-ACS3210E, the app in the model’s specification gives you energy monitoring and control of the 10–32 A current — but a timed start is not a stated line in that specification. Here is how to build that routine on what the unit offers, and prove it from the session record.
Key Takeaways
- The tariff sets the price; the charger’s job is to land the session inside the cheap window.
- Monitoring and current control are stated for this unit; a timer is not — confirm it or use the car’s window.
- Only energy that spills past the window’s end is billed at peak: spill × rate gap.
- Check the session records after week one; a stable pattern means the routine works.

What the App States — and What It Does Not
Read the specification literally. Energy monitoring is listed: the charger records each session’s kilowatt-hours. The current is set in the app, across six steps — 10, 13, 16, 20, 24 and 32 A. A timer is not listed, so treat scheduling as a question to check in your app version and manual, not a promised feature. A fixed wallbox usually lists scheduling as a standard app job (see our guide to wallbox app features). The wider strategy: our guide to smart charging and time-of-use tariffs.
Three Ways to Land the Session Inside the Window
| Route | How it works | What to check first |
|---|---|---|
| A timer in the app | If your app version offers a start or stop time, set it to your tariff window | That a timer exists in your version — not a stated line |
| The car’s own timer | Most EVs hold a window in the car; the charger supplies power when asked | The car’s window matches your tariff; the limit is set for the socket |
| Plug in and shape the session | Start at the window’s opening; pick a step that finishes in time | The duration maths below |
The third route is where this charger earns its keep. Duration is energy divided by power: adding 30 kWh at 32 A (about 7.4 kW) takes roughly 4.5 hours with losses allowed for; at 16 A (about 3.7 kW), about nine. In a six-hour window, one finishes inside and the other spills. Stepping down is never a discount — it only stretches the session.

Prove It With the Energy Record
Monitoring is the half of off-peak charging most drivers skip. After week one, read the app session records and check three things:
- Energy per session. A stable nightly figure means a regular routine — and it is the number your bill should roughly reflect.
- Sessions finishing before the window closes. A car still drawing when the cheap hours end bills the overflow at peak.
- The step you actually used. Repeated spill is a step problem, not a tariff problem: step up where the circuit allows, or start earlier.
Only the overflow is penalised; energy inside the window costs the off-peak rate at any setting. For the energy side, see how many kWh it takes to charge an EV.
The Arithmetic, With Your Own Two Rates
Your tariff sheet holds your real prices; no article can quote them. Two invented rates show the shape — €0.20 per kWh off-peak, €0.35 at peak, for illustration only. A 20 kWh night fully off-peak costs €4.00; let 5 kWh spill into peak hours and it costs €4.75 — the extra is just the spill times the gap, 5 × €0.15. Run the same line with your own rates for your real figure.
The Charger in This Routine
The EV-ACS3210E is a 32 A Type 2 portable charger: single-phase, about 7 kW at its top step, adjustable from 10 to 32 A in six steps, with app control, energy monitoring and OCPP-readiness in its specification, a 7.5 m cable and an IP66 rating. EVDANCE is a Shenzhen manufacturer founded in 2011, and the unit carries its 3-year standard warranty. For an off-peak routine, its useful tools are those steps and that monitoring.
Frequently Asked Questions
Does the EV-ACS3210E app have a built-in charge timer?
Not a stated line in the model’s specification — check your app version and manual. If there is no timer, the car’s own window does the same job.
Does charging at a lower current save money on an off-peak tariff?
No — price follows the time of day, not the amps. A lower step stretches the same energy over more hours, and hours past the window’s end bill at peak.
How do I know my off-peak routine is working?
Read the app’s session records for a week. Sessions finishing before the window closes, at a stable nightly figure, mean the routine holds; repeated spill means the step is too low or the start too late.
