Electric Jaguars will be tested to prevent them disrupting household appliances

Jaguar Land Rover has opened a new test center to ensure its latest generation of power-hungry electric cars don’t interfere with TV screens and smartphones.

The new Warwickshire facility will ensure electronic devices are shielded from their cars and vice versa, a growing challenge as battery-powered vehicles are connected to more and more data. The new Range Rover Sport, launched earlier this year, was the first vehicle to undergo the tests and was fitted with 4G, 5G, WiFi and GPS signals to ensure it could cope .

For most people, the memory of a passing car turning a TV screen into a blur of white noise will be a distant memory, but the phenomenon threatens to return due to electric vehicles.

Electric cars are at greater risk of radio wave interference because they operate at higher voltages and more current, which can deliver a stronger electromagnetic field.

Jaguar Land Rover’s Peter Phillips said: “EVs are much more demanding” because of the higher electrical power they manage.

“Today, if you have an EV, you take your EV home, plug it into your garage charger, and you don’t want the car interfering with the radio or television at home while it’s charging,” he said, adding that without testing, plugging in a lawnmower while your car is charging could also turn off the charger.

In addition to the higher voltage issues, another challenge is the range of sensors and safety features that will be added to all cars – both combustion and battery powered. Cameras, radar and other sensors must be kept free of interference in order to function.

“Automation is part of that,” added Mr. Phillips. “Some radar systems on the cars work in the electromagnetic radio spectrum, the autonomous adaptive cruise control has a radar in front of the car.”

Car manufacturers have to follow strict rules to sell their cars in most markets and to comply with the law.

But beyond the legal bases, automakers want Bluetooth and Wi-Fi to work in their cars so drivers can play music, take calls and get live map data while driving.

In practice, strict regulations have meant that a car can be started and driven without disturbing the neighbors’ enjoyment of a television program, but the rapidly evolving nature of electric car technology makes testing prudent.

Jaguar Land Rover plans to make the Jaguar range fully electric by 2025 and phase out petrol around 10 years later. The company is the second largest automaker in the UK. Electric Jaguars will be tested to prevent them disrupting household appliances
