Smarter grid integration, without extra hardware
As EV charging becomes more connected to grid requirements, the ability to respond to external control signals is becoming increasingly more important.
This is especially relevant in markets such as Germany and Switzerland, where grid-side control is becoming an important part of EV charging infrastructure. As charging grows and grid requirements evolve, the ability to respond to external load shedding signals is no longer just a technical detail. It is becoming a practical requirement for smarter, more grid-ready installations.
This is where load shedding comes in.
What is load shedding?
Load shedding allows a charger to respond to an external control signal and temporarily reduce charging power when the local grid is under pressure.
In many cases, this signal originates from the Distribution system operator (DSO) or grid operator side, either directly or through utility-side control equipment such as a ripple control receiver or switching contact.
In simple terms, it helps charging infrastructure work more smoothly with the grid, especially during peak demand or constrained local network conditions. For installers and site owners, it is becoming an increasingly practical part of building grid-ready EV charging systems.
The NexBlue advantage: direct signal input at the charger
NexBlue takes a simpler approach.
Selected NexBlue chargers support direct integration of compatible load shedding control signals into the charger itself. That means the signal can be connected directly to the charger, without requiring an additional intermediary controller to receive and pass it on.
This creates a cleaner installation architecture with clear practical benefits:
- lower installation cost
- fewer components
- less wiring
- less cabinet space
- faster deployment
Most importantly, it helps avoid unnecessary extra hardware between the grid-side signal and the charger.
A more straightforward way to integrate load shedding
In many conventional setups, the utility-side control signal has to pass through additional intermediary hardware before the charger can respond.
NexBlue takes a smarter path.
With direct signal input at the charger, the architecture becomes cleaner from the start. Fewer extra devices. Less wiring. Less installation effort.
The result is a more streamlined system design, lower installation cost, and fewer possible points of failure. A practical advantage that can make a real difference on site.
What signals are supported?
NexBlue supports two types of load shedding control signals:
Switch signal
For installations where the external control equipment provides a switching signal (dry contact).
Voltage signal
For installations where the external control equipment provides a voltage-based control signal (5–48 V).
This gives installers the flexibility to work with different local control setups while keeping the integration simple.
Simple connection through the Multi-function adapter kit
To enable this function, the charger is connected using the NexBlue Multi-function adapter kit, sold separately.
This provides a straightforward connection path for supported load shedding inputs and makes on-site integration easier and more efficient.
Supported models
Based on the current product scope, load shedding signal support is available for:
- NexBlue Edge 2
- NexBlue Edge Max
- NexBlue Delta
- NexBlue Delta Max
Currently supported regions
- Germany
- Switzerland
Support for additional countries will be introduced as needed.
Simple installation, smart control
As grid requirements continue to evolve, the most effective charging solutions are the ones that combine technical capability with installation simplicity.
By supporting both switch signal and voltage signal input directly at the charger, NexBlue makes load shedding integration cleaner, easier, and more cost-efficient.
Less extra hardware.
Less installation complexity.
