Why is my vechile charging slowly?

A charging facility always has a maximum capacity to work within. Some charging facilities have a high capacity, while others have a lower capacity. It is not always possible to increase the available capacity due to technical or financial limitations.

In addition to the maximum capacity, the available power often needs to be distributed across multiple charging points.

What happens during periods of high charging demand?

The most common solution is to use load balancing.

Load balancing distributes the available power across multiple charging points, allowing several vehicles to charge at the same time.

• Multiple vehicles charging at the same time and simultaneity factor: When several vehicles are charging simultaneously, the available power is shared between them. This can result in a lower charging speed per vehicle.
• Fewer vehicles: If only a few vehicles are charging at the same time, charging speeds will generally be higher.

In some cases, it is not possible to enable load balancing. In such situations, it is common to manually limit the power available to charging points. This reduces charging speeds but helps distribute power more evenly across multiple charging points.

But why is this necessary?

The answer is simple: to prevent the facility's electrical protection from being overloaded.

If a fuse or circuit protection device is triggered, all charging will stop. Without these measures, this could happen repeatedly and cause unnecessary interruptions.

An installer will typically determine whether a charging facility should use load balancing or whether charging speeds need to be limited to avoid such issues.

Are there any other reasons why a vehicle may charge slowly?

Yes, absolutely. Here are some common reasons:

• Charging Cable Type: Not all charging cables support high charging power.
• Vehicle Model: Different vehicle models support different maximum charging speeds.
• Vehicle Settings: Check that your vehicle is not configured for reduced charging speed or scheduled charging.

These are some of the most common reasons, but there are also other factors that may affect charging speed.
