Weiland Bruch, corporate communications chief for BMW i vehicles, told news agency Headlineauto: ‘We will be making an announcement soon, so watch this space.’

The move is expected to help increase uptake of EVs by allaying driver concerns over the time taken by charging and the difficulties posed by home-charging for those who live in high rise buildings.

The move come as BMW considers increasing production of its i3 following higher-than-expected demand. The brand is already producing 70 i3 models a day at its plant in Leipzig just a few months after its European launch and customer orders are now banked up almost six months ahead. This is before the car is launched next month in the US and China in the summer.

Bruch added: ‘Clearly we do not want people waiting five or six months for their cars and as we launch into more markets we need to think about increasing production.’

Meanwhile the i8 petrol-electric sports car begins series production in Leipzig in April.
