Electrifying EV surge protection
Pave the way to a smooth ride with DEHN
Electric vehicle charging infrastructure, from AC/DC charging stations to versatile wall boxes, is in high demand as the EV industry continues to experience a financial and technological boom.
Installing these electrical systems is pointless if they aren’t properly protected from transient voltage threats. As an international expert in power quality protection, DEHN is your go-to partner for protecting your EV infrastructure, as well as the people and vehicles that rely on it.
While the EV industry has experienced rapid growth, the regulatory bodies surrounding it, such as the NEC, have not kept up. Their standards for grounding, as well as lightning and surge protection, are outdated and leave your electrical systems vulnerable if you don’t take extra steps to safeguard them.
DEHN has the solutions and surge protective devices you need to be an industry leader in every aspect of your market, including surge protection for EV infrastructure.

In a young market like the EV industry, reliability is top of mind. If you’re unable to establish yourself as a trustworthy power provider for EVs from the start, you could gain a negative reputation with other industry entities and consumers alike.
Building your reputation starts with ensuring consistent power quality. An ungrounded EV charger installation is a recipe for disaster that will eliminate your ability to meet that goal.
Both internal and external transient surge events can cause system-wide damage and disruptions that can wreck your electrical equipment. This can result in excessive repair costs, service outages, and even damage to charging vehicles and the people charging them on top of disturbing your overall power quality.
Here are some additional threats to your EV charging systems:
External electrical threats to EV infrastructure
External transient voltage can include direct lightning strikes, indirect lightning strikes, and transient surges from external systems, such as the power grid.
When lightning strikes a charging station or the ground somewhere nearby, it can cause an overvoltage that breeds devastating damage to your system. Cloud-to-ground lightning strikes can also cause fires that destroy entire stations.
An inside job – internal transient surge risks
About 80% of all transient voltage is the result of electrical noise from your own internal systems. While these electrical spikes and surges are normal and often the sign of a healthy system, they can cause irreparable damage if left unchecked.
For example, a switching operation in transformer stations or a charging post can create switching surges that compromise the integrity of the function of the surrounding electrical components. If such a power surge were to occur while a vehicle is charging, it’s likely the vehicle will also be damaged severely.
DEHN has solutions tailored to the EV industry. From grounding systems for charging stations to external lightning protection for wall boxes, our proven protective concepts can minimize the adverse effects of any transient voltage event.
Power quality protection across a range of EV infrastructures
DEHN started as a family-owned electrical engineering company more than 100 years ago and has grown into a top provider of EV protection solutions. Our transient voltage protection isn’t limited to just one type of charger, we can work with you to safeguard a variety of EV infrastructure, including:

EV wall box chargers bring the power of advanced charging stations to compact, private spaces, such as single-family homes or multi-story parking garages. As electrical vehicles become more common among the general public, wall boxes meet the demand for constant, individual access to EV charging equipment.
However, this convenient charging method can be wiped out in a flash if left unprotected. Overvoltage from a transient surge or lightning strike can quickly render wall boxes inoperable and spread damage to any connected electrical components, such as your home’s electrical system and your charging vehicle.
Protecting wall boxes from transient voltage damage presents a unique challenge as these switchgear cabinets have a highly compact internal environment.
Luckily, DEHN has specialized solutions for small charging spaces. Our strategies stand out because we can install effective protection directly into limited spaces without the need for costly additional cabinets or expanded infrastructure.

High-power charging parks are a faster public charging station alternative to a standard EV charging system. These DC chargers can range between 150 to 350 kW charging speeds, making them highly beneficial infrastructure for EV owners balancing busy schedules.
To protect people using your EV chargers and the safety and mobility of their electric vehicles, it’s important to proactively install efficient transient voltage protection systems.
While it is faster, high-power charging stations face the same electrical risks as standard chargers. Direct and indirect lightning strikes can damage infrastructure through fire or surges, while earth faults and short circuits in the power grid could cause an overvoltage that diminishes your power quality for the long term.
It only takes one split-second strike to a single electrical component to bring down the entire charging station system. Get the grounding systems and protective solutions you need to ensure consistent, fast charging with DEHN.
Charge up against electrical threats to charging stations
Charging stations remain some of the most common types of EV charging infrastructure. They are often in open, public spaces, and consist of several electric vehicle chargers grouped together for a convenient charging space.
Both AC and DC charging facilities, as well as connected vehicles, are vulnerable to electrical events if left ungrounded and unprotected. In the case of a thunderstorm, the electrical components inside these often outdoor stations are at risk of damage from a lightning-related electrical power surge. The controller, meter, and communication system are especially vulnerable to overvoltage.
Depending on the location and characteristics of the EV station and the electrical threats it faces, its protection needs change and evolve. Additionally, as charging stations are often spread out across a space and consist of several diverse electrical systems working together, they require a tailored transient voltage protection concept that includes grounding systems, equipotential bonding measures, and standard lightning and surge protection systems.

The future of public transportation is electric… but are your DCFC and bus charging stations prepared for the transition?
Part of the EV industry expansion has been the introduction of electric vehicles and charging into the public transportation sector. Many new public mobility concepts across the U.S. include electrified bus fleets.
Like privately owned electric vehicles, these critical transporters need reliable charging stations that are protected against common transient voltage threats. If an ungrounded, unprotected charger is rendered inoperable by an electrical event, it will affect much more than a single commuter’s trip to work.
Overvoltage could wipe out significant portions of the fleet or cause delays in transportation schedules due to a lack of charged vehicles and buses. As the company behind the charging infrastructure, local governments could hold your company publicly and financially accountable for any damage incurred to connected vehicles and systems.
