Surge protection is a safety feature that prevents damage to your electric vehicle (EV), charging cable, and home electrical system caused by sudden voltage spikes. These spikes, also called surges, can occur due to lightning strikes, grid switching, or faults in the power network. A surge protector absorbs or diverts this excess voltage before it reaches sensitive electronic components, acting as a barrier between your EV and harmful energy surges.
Why surge protection matters for EV charging
Modern electric vehicles contain complex electronics, including battery management systems, charging modules, and onboard computers. These components are sensitive to overvoltage conditions, and even a single power surge can cause permanent damage or significantly shorten their lifespan. Whether you charge via a home charging station or a mobile charger, surge protection helps maintain the safety and longevity of your vehicle's electronics.
Built-in protection in Voldt® products
All Voldt® EV charging cables, including our mobile charging solutions, are designed with built-in safety features such as overvoltage protection, overheating protection, and fault detection. For instance, the Voldt® mobile charger for domestic sockets includes internal surge protection that complies with CE and TÜV standards. This ensures that, even in the event of a sudden voltage spike, your EV and your household installation remain protected.
Extra layers of protection
For added safety—especially in areas prone to lightning or grid instability—it is advisable to install a Type 2 or Type 3 surge protection device (SPD) at the main distribution board of your home. These devices provide whole-house protection and can work in tandem with the surge protection already built into your charger. It’s a proactive investment that enhances the safety of your EV infrastructure and helps avoid expensive repairs or insurance claims.
