myenergi zappi Charge Blockedwhat it means
Not a fault. The car keeps asking to charge after it already reported complete, and the zappi has stopped answering.
Before you start
What this means
Charge Blocked is one of the zappi displays that carries no code number, and it is worth understanding because it looks like a refusal and is actually the charger being sensible. myenergi describe it as the EV having repeatedly tried to start a charge although it previously reached Charge Complete, and they give three reasons that happens: the battery is full, the EV's own charge limit has been reached, or a timer in the car stopped the charge. The action is simply to unplug the EV, and charging will continue when the EV is plugged in again.
What is going on underneath is a conversation between two devices that each think the other should be doing something. Modern vehicles top up periodically after reaching their target, or wake up and ask again after a timer expires, and a charger that responded to every one of those requests would cycle its contactor repeatedly for no benefit. So after the car has declared itself complete and then keeps asking, the zappi stops answering and tells you why. The most common real-world version of this is the car's own charge limit. Many owners set a limit of eighty or ninety per cent to look after the battery, and when the car hits that limit it reports complete — but its logic may still poll for more.
Nothing is wrong with either device. The second most common is a departure timer in the car interacting with a schedule on the charger, which is worth checking because two schedules set independently produce behaviour that neither of them describes. The practical thing to take from this is that Charge Blocked is not a reason to book anything. Unplug, and the next session will start normally. If it happens every single night, look at the car's charge limit and its timer settings rather than at the charger.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| The battery is full | myenergi’s first stated reason. The car reached its target, reported complete, and then continued to ask. | Common |
| The car’s own charge limit has been reached | Very common on owners who cap at eighty or ninety per cent for battery longevity. The car declares complete at its limit while its charging logic keeps polling. | Common |
| A timer in the vehicle stopped the charge | myenergi name this specifically. A departure or charge timer in the car can end a session the charger was happy to continue, and the resulting requests look like repeated restart attempts. | Common |
| Two schedules working against each other | Not myenergi’s wording but the practical version of the timer case. A schedule in the car and a schedule on the charger, set independently, produce behaviour neither describes. | Occasional |
What to try yourself
Check the state of charge on the car. If it is at or near your chosen limit, this display is the expected outcome rather than a problem.
Unplug the vehicle. That is myenergi’s published action, and charging continues normally when the car is next ready.
Look at the charge limit set in the car. A limit of eighty or ninety per cent will produce this at the end of most sessions and is not worth changing if it is deliberate.
Check for a departure or charge timer in the vehicle. myenergi name an EV-side timer as one of the three causes, and it is the one owners forget they set.
If you have schedules on both the car and the charger, simplify to one. Two independent schedules produce results that neither of them explains.
Get a registered electrician to look at your myenergi zappi ev charger
We do not pass enquiries to a repair firm, so there is no form here. When you book a registered electrician, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.

Common questions
Is something wrong with my charger?
No. myenergi publish this as a state rather than a fault, and it carries no code number for that reason. The car has already reported charge complete and is asking again, and the charger has stopped responding to repeated requests. Unplugging clears it.
It happens every night. Should I be concerned?
Not about the charger. Nightly Charge Blocked usually means the car is hitting a charge limit you have set, or a timer in the vehicle is ending sessions. Both are working as intended, and the display is just the charger explaining why it stopped answering.
Will unplugging lose my schedule?
No. The schedule lives in the charger and the app, not in the connection, so unplugging and re-plugging leaves it intact. The next scheduled session will start as normal, subject to the usual randomised delay.
