Do I need to run a data cable to the charge points for load management?

Wireless load balancing solution

There is no need to run a physical data cable between CT clamps and charge points. All charge points can be load limited wirelessly when connected to NexBlue Zen via our cloud. This eliminates complex wiring requirements and ensures a more flexible, scalable setup.

For charge points to be load balanced, they must have an active connection to our cloud, either via Wi-Fi or 4G. Similarly, the NexBlue Zen must be connected to the internet, either through Wi-Fi or via the ethernet port on the device. Importantly, the charge points and NexBlue Zen do not need to be on the same local network to communicate, as all load balancing and management occur through the cloud.

Why Load Balancing is Essential

Load balancing is critical in environments where multiple EVs are charging simultaneously and/or where electrical supply is limited. By intelligently distributing the available power among connected charge points, load balancing helps to:

•Prevent Overloading – Avoids exceeding the property’s maximum electrical capacity, reducing the risk of tripped breakers or power outages.

•Optimize Charging Efficiency – Ensures that all vehicles receive an appropriate share of power based on real-time demand, maximizing available capacity.

•Enable More Charge Points – Supports the installation of multiple charge points without the need for costly electrical upgrades.

•Improve Safety and Compliance – Adheres to electrical safety regulations by dynamically adjusting power loads in response to fluctuations in energy usage.

By ensuring that charge points and the NexBlue Zen maintain a stable cloud connection, users benefit from seamless load management, making EV charging both efficient and reliable.
