Surge protection for EV charging stations
Solutions that help you charge ahead with confidence
The number of registered electric vehicles continues to grow as the general public and industry leaders alike recognize the benefits of environmentally friendly mobility options. Through the connection of charging infrastructure with the power grid, the electric vehicle industry has solidified its place within the energy revolution.
While EVs are at the forefront of innovation, the electrical infrastructure they rely on, specifically AC/DC charging stations, is susceptible to the same power quality disturbances as other electric technology and equipment.
To combat these threats and prevent harm to people and damage to charging vehicles, transient voltage solutions are critical. From lightning protection to grounding systems, proactive protection starts with education and awareness.
Get in the know about the specific risks to your EV charging stations with a risk assessment from DEHN. As a global leader in transient voltage solutions, we can protect your EV charging operation’s reputation and equipment from all sides.

How does transient voltage damage charging stations?
As EVs become more popular among the general public, charging infrastructure is in high demand as well. From private, semi-public, and public areas, these electric vehicle chargers are being installed at places of work, parking lots at medical facilities and shopping centers, and residential areas such as apartment complexes.
Unfortunately, the more unprotected AC and DC charging stations are installed and used the greater the risk of damage or injury caused by transient voltage. These electrical events don’t discriminate – they can wreak havoc on the electrical components within your charging station, as well as any connected vehicles and even nearby drivers.
An external transient voltage, such as direct lightning strikes, can destroy satellite systems with interconnected charging points. On the other hand, overvoltage – an internal transient – can quickly exceed the 2.5 kV of dielectric strength of chargers and connected EVs alike, damaging the vehicle beyond repair.
The list goes on and on, but luckily there are several solutions at your disposal. Opportunities to protect your EV chargers can be grouped into two main categories: lightning and surge protection, and grounding and equipotential bonding.
At DEHN, we specialize in all types of transient voltage protection because we believe a holistic approach is the best solution. While some industry regulations or protective bodies require one aspect of our power quality solutions, we are one of the few electrical engineering companies in the market with a proven fix to every electrical problem facing your systems. Not to mention we have more than 100 years of experience working with companies in every industry across the globe, including EV.

Dangers posed by lightning strikes and similar external transient surge events are increasing with every passing year as climate change makes extreme weather events the norm.
A direct lightning strike can fry your electrical components in less than a second. It could also cause a fire that spreads far beyond your charging station, making you liable for more than just the damage to your own systems.
When it comes to surge, it could be as simple as a small overvoltage from switching operations inside your EV charger installation. It only takes a tiny spark to start a chain reaction of damage.
Not unlike traditional lightning rods, external surge and lightning protection systems work by harnessing the energy of an overvoltage and directing it away from vulnerable systems. This ensures that the intense amount of energy doesn’t flow through any chargers or connected EVs.
Stay grounded with DEHN
Grounding and equipotential bonding solutions are often a direct response to the threat of indirect lightning strikes.
When an indirect lightning strike hits at any point, it shoots a powerful current through the ground that can run up into your unprotected charging systems from miles away and cause a detrimental electrical power surge. There is also the risk of dangerous step and touch voltages to drivers who use ungrounded charging stations to power their EVs.
Our grounding systems work by distributing lightning current over a larger area through an intermeshed, low-impedance, interconnected system that reduces overvoltage. These systems also use additional control measures in high-traffic areas, like around your charging station, to minimize the threat of step and touch voltages.
When we say comprehensive, we mean it. At DEHN, our solutions for EV charging stations include everything you need to protect people and electrical systems alike.
For charging stations with low-voltage switchgear installation, our protection systems can maximize your safety and help you keep your reputation as a provider of safe, reliable charging solutions for EVs.
Your time, money, and reputation are on the line when something goes wrong with your charging infrastructure. Don’t wait until it’s too late. Contact DEHN to schedule a risk assessment and learn what surge protection devices and other solutions can help you minimize risks to your electrical systems.
