If you are stuck in an Electric Vehicle, in traffic for an hour, how long will it take for the battery to drain?

This is a genuine problem the automotive industry currently faces and the battery life of Electric Vehicles (EVs) has been in the spotlight over the last couple of months, as this is one of the main reasons there is a lack of consumer confidence.

Electric cars are still relatively new and everyone is just starting to find out a little bit more of what to expect from them in the future.

However, it isn’t just consumers that have potential issues about the longevity of EVs. Automotive professionals from garage owners to mechanics, and even parliamentary personnel, have all been raising concerns about the lack of charging stations, battery life and a lack of EV knowledge when it comes to maintenance and servicing.

So...have you ever wondered what would happen if you’re stuck in a five-mile traffic jam with an electric car that doesn’t have a full charge?

EV battery life simulation by Which?...

To help with consumer confidence, Which? used the latest Volkswagen ID.4 electric and through conducting the simulation of being at a standstill for an hour with the lights on, changing the cabin temperature, streaming music, and watching films on rear-seat screens had only a little influence on energy consumption, resulting in a loss of only 2% capacity, or eight miles of range.

The test was conducted with music being streamed through the Android Auto system embedded into the infotainment system to see how battery capacity was affected by the vehicle remaining stationary.

Both front heated seats were also set to the highest temperature, the air conditioning was on full blast, the dipped headlights were turned on and a tablet was plugged into a USB connector in the back seats was playing a movie.

The VW’s battery only lost 2% of its 77kWh capacity after just over an hour and 15 minutes, equating to only eight miles of range.

Which? did note, however, that its controlled test was conducted on a hot day, and that cold temperatures will have a greater impact on the car’s power consumption and said that they would conduct a similar test during the winter.
