Volkswagen is partnering with Tesco to make free charging for electric cars available for customers at some Tesco stores from next year.
The partnership plan to install almost 2,500 charging bays at up to 600 stores by 2020.
A standard 7kW charger will be available for free, but drivers will have to pay for a faster service.
Customers will be able to leave their cars to charge while doing their shopping, which should give time for a “substantial” free charge, VW said.
How long it will take to fully replenish the battery will depend on the type of car. A company called Podpoint will build the charging facilities for VW and Tesco.
Volkswagen has two electric vehicles on the market in the UK, the e-Golf and the e-Up. It has sold about 1,350 of the cars since they went on sale four years ago, but has plans for a massive expansion.
By 2020 it wants to offer an electric version of all its models.
