EV Surge Protection At Charging Stations

One of the fastest growing markets on earth is within the electrical vehicle (EV) space, as rising gas prices combined with increased awareness about emissions and climate damage takes hold. There are currently more than 5 million electric vehicles on the road, and every year that number is expected to substantially increase as governments around the world tighten emissions standards. Another factor that comes into play with regards to increasing electric vehicle sales is the development of sportier and more powerful models, especially with regards to Tesla. tesla is one of the EV manufacturers that has developed proprietary charging technology, and also installed charging stations that do not accept hookups from different models. Tesla vehicles can be charged at standard EV charging ports as well as Tesla supercharging stations. Tesla’s rapid chargers have dramatically reduced the amount of time it takes for a vehicle to fully charge, coming far closer to the desired one-half hour goal, while the standard grid of EV chargers has lagged behind, creating extended wait times that are deemed as unacceptable for many who are considering an electric vehicle.  The reason for this lengthy charging time is that most buildings are not able to deliver the necessary AC power to the charger, plus the vehicles are not constructed in a way that their rectifiers can handle the high AC currents. To solve this issue, the existing network of charging stations worldwide must be upgraded to stronger DC currents. This will mean upgrading individual charging stations with the latest DC fast charging technology.

In order to upgrade existing charging stations to the necessary DC current, numerous expensive components are going to need to be installed. It will also be common to separate the transformer, inverter, cooling and user units. This means a far wider footprint than is currently seen at charging stations, making the entire sequence of components far more susceptible to damage as a result of lightning strikes and power surges.  Lightning strikes to the area surrounding equipment as well as direct strikes to components can not only cause catastrophic failures, but also dangerous situations where life could be lost if the owner of the EV is sitting in or around their car. Because of these dangers of loss of life and property, upgrading to a more modern network has been slow. Only through the development and installation of technologically advanced surge protection devices and lightning diversion components is the rollout of upgraded networks becoming more economically viable, as operators previously viewed the risks as not being worth the reward. Raycap is a technology innovator in the area of surge protection that can assist in the rollout of a more effective charging grid for electric vehicles, and through integration of these high function devices can operators rest assured that their investments are safer. The EV market is moving into more widespread adoption, and Raycap technology is at the core of protecting it.
