EV owners might want to consider the risks of putting a heat source near a lithium battery. If that goes wrong, it can really go wrong. But if they don’t or can’t preheat their battery in cold conditions, e.g. it’s parked in the street, they can look forward to a significant range reduction, made worse by using the car heater.

In the wake of the coldest night of the winter in the UK, Edmund King, President of the AA, has issued guidance to electric vehicle (EV) owners, emphasising the importance of preheating their cars and charging overnight, reports Energy Live News.

As the nation grapples with snow and ice that led to the closure of numerous schools, Mr King warns that colder temperatures can adversely affect EV batteries, leading to longer charging times and reduced efficiency.

The AA noted that electric cars may experience a reduction in range ranging from 10% to 20% in colder temperatures.

This is attributed to the diminished efficiency of the lithium-ion battery, exacerbated by drivers activating features like heating.

This advice comes as electric vehicle users in the US, particularly in Chicago, have faced difficulties due to freezing temperatures, with reports of Tesla owners abandoning their vehicles.
