Proactive protection for wall box EV chargers

Big solutions for your smallest spaces

As the electric vehicle industry continues to expand and join the ongoing electric revolution and surge of smart devices, the demand for more dynamic, innovative charging increases as well. One response to this need has been wall box chargers.

This compact EV charger offers EV users increased privacy, independence, and charging capacity. Often installed at private residences or semi-public parking garages and residential complex parking lots, these mini charging stations pack the same powerful punch as a full-size charger.

Unfortunately, like their larger counterparts, electric vehicle wall box chargers also are vulnerable to power quality disturbances that could destroy their internal systems, as well as damage any connected electric vehicles or other electric infrastructure, such as a home’s power systems.

Lightning protection, surge protection, and other types of transient voltage solutions are non-negotiable if you want to ensure a safe, reliable power supply to charge your EV. At DEHN, we specialize in protective solutions for EV wall box chargers.

Our risk assessment is the first step. Get in the know about the threats to your charging systems so you can make informed decisions for proactive protection.

Unpacking electrical threats to EV wall box chargers

Most people know a wall box as the electrical box inside the home, which houses and protects the electrical switches and terminal compartments. An EV wall box charger is similar in that it provides a closed, compact environment for all of the electrical equipment needed to charge an EV.

These versatile chargers can be installed outside, in garages, in multi-story parking facilities – anywhere where EV users need to recharge their batteries and connect to the same electrical circuit as the rest of your home or building. No matter where it’s installed, every wall box has one thing in common – without proper protection, transient voltage-related damage isn’t a matter of “if,” but of “when.”

From internal threats such as overvoltage from a switching operation to external events like a direct lightning strike, wall box chargers will experience a type of transient voltage and be damaged in the process.

The negative effects can range from broken parts that require costly repairs to a complete system-wide power outage. You may have to replace the entire wall charger if enough damage is done. The worst part is that surge can also spread to any connected electrical components. Your charging electric car could be compromised, as well as your home’s or parking garage’s other electrical systems, which could experience a surge transferred from the charger through the shared power source.

DEHN offers power quality protection for diverse applications within wall box structures. Our intelligent EV charging systems for the EV industry include the smallest designs on the market, perfect for compact wall box chargers.

Compact complexities: The challenges of installing wall box protection

Space in a wall box is highly limited. Every component inside is critical to the function of the system. 

While a wall box charger can’t function indefinitely without proper transient voltage protection – eventually lighting will strike – most common solutions in the North American market are too large to be implemented into the charger’s internal environment.

The common solution is often to add additional housing near the wall box and then connect the protection systems from there. Not only does this option significantly increase costs, but it can also spoil the overall appearance and construction of the original design.

With DEHN, you don’t have to compromise between safety, budget, and aesthetics. Our tailored solutions for wall box chargers include surge arresters and other transient voltage protection systems with variable installation options, so they can fit in almost any space, including an already crowded wall-mounted electric car charger.

DEHN’s solutions simplify the previously complicated protection process for this charging infrastructure and boast an easy installation. No matter if they’re retrofitted or added with a new installation, our products are standouts in the industry for their small size, flexibility, and versatility.
