EV Chargers
What are EV chargers?
Electric vehicle (EV) chargers are essential devices that provide power to electric cars, enabling them to recharge their batteries. With the growing adoption of EVs, these chargers are becoming increasingly important, offering various types such as home, public, and fast chargers to support sustainable and eco-friendly transportation.
As the world shifts towards greener transportation solutions, electric vehicles (EVs) have surged in popularity. However, with the increase in EV ownership comes the need to address potential risks and vulnerabilities in their charging infrastructure. One pertinent question arises: Do electric vehicle chargers need surge protection? The answer to this question has evolved with changing regulations and technological advancements, making it a topic of keen interest for EV enthusiasts and homeowners alike.
Surge Protection Devices
Surge Protection Devices (SPDs) are specialised equipment to safeguard electrical appliances, including EV chargers, from power surges or transient overvoltages.
A power surge occurs when a rapid and substantial increase in voltage surpasses the normal 230-volt flow. While these surges are short-lived, they can cause severe damage to electronic devices and appliances. Lightning strikes, switching within the power grid, faulty wiring, and electrical overloads are common triggers for such surges.

What are the rules on SPDs?
The regulations governing the need for SPDs in EV charger installations have undergone significant changes in recent times.
The 18th Edition Amendment 2 of the Wiring Regulations, effective since September 2022, mandates that all new electrical circuits, including those for EV chargers, must have SPDs fitted. Consequently, from a regulatory standpoint, new EV charger installations must incorporate surge protection.
For those who prioritise safety and longevity, integrating an SPD into your EV charger installation is a sensible choice. The relatively minor upfront cost of an SPD pales in comparison to the potential expenses associated with electrical damage.
Moreover, some EV charger manufacturers and installation companies may uphold warranties even without SPDs, but it’s essential to remember that any damage caused by power surges might not be covered.
In the realm of electric vehicle chargers, the debate about the necessity of surge protection rages on. With the ever-evolving regulatory landscape and advancements in technology, the choice to integrate an SPD into your EV charger installation rests with you.
However, considering the potential risks, the benefits of safeguarding your investment and your home far outweigh the initial cost.
In a world where being prepared is synonymous with being prudent, opting for surge protection for your EV charger offers peace of mind and security for both you and your beloved electric vehicle.
