The app, which is compatible with the Focus Electric, and Ford’s plug-in hybrid C-MAX Energi and Fusion Energi, monitors usage and provides data about battery charge and the locations of 12,500 charging points through the PlugShare database to help drivers plan journeys around infrastructure.

Ford said lunchtime was the most common period during which drivers searched for local charging points. Most were able to increase their battery-powered mileage within the first 30 days of ownership, contributing to a rise from 41% of all journeys being on electric power at the start of the year, to 60% now.

Joe Rork, MyFord Mobile product manager, said: ‘The daily percent driven in electric mode continues to inch upward, suggesting drivers are using the information provided by MyFord Mobile to change how they drive and really get the most out of their vehicles.’

In its latest update allows drivers to check journey distances, energy consumption, regenerative braking and assess driving scores, aimed at helping further improve the range achieved from a single charge.

Ford's part-electric vehicles will be available in Europe beginning with the Focus Electric, followed by the C-MAX and Fusion-based Mondeo hybrids later in the year. Plug-in versions of the C-MAX and Mondeo are as yet unconfirmed for the UK.
