Published on: 27/03/2020

The remarkable surge in demand for filter solutions used in electric vehicles

The last four years have seen a remarkable surge in the demand for electric vehicles in the UK with new registrations of plug-in cars increasing from 3,500 in 2013 to more than 227,000 by the end of August 2019. Today there are over 227,000 electric cars and 8,500 electric vans across 130 models with 25,733 charging points. registered in the UK, with thousands more being manufactured every month.

Electronic vehicles have numerous  clear advantages over internal combustion vehicles for the end user, such as zero emissions, instant torque and low noise. In the first eight months of 2019 saw a new record of almost 60,000 electric vehicles being registered in the UK in the course of a year.

Electromagnetic Solutions for Electric Vehicles

When charging a contemporary EV, the mains AC needs to be rectified to the DC required by the batteries, a process that creates fluctuations in the mains signal. When this effect is multiplied by thousands of EVs, these small fluctuations will create disruptive noise and harmonics. These disturbances can interfere with frequency sensitive equipment, particularly power line communication (PLC) devices.

Harmonic interference doesn’t just effect PLC systems, however. Any frequency sensitive application, such as an audio-visual setup, can suffer from unwanted signals. Disruptive harmonics travelling in the kilohertz range over unshielded wires — such as power lines — can even emit radio waves.

For those crucial filtering applications, GD Rectifiers offers an extensive range of electromagnetic compatibility filters. Whether you’re looking to remove hiss from a speaker or source a new sinusoidal filter to drive your electric motor, we’ve got you covered.
