The size of the charge network available to Ford electric vehicle drivers has increased more than threefold in readiness for first UK deliveries of the Mustang Mach-E performance SUV, the automaker's local unit said on Friday.

It is expanding its long standing business partnership with BP by adding Pulse – the biggest public charging network in the UK – to the Ford Pass charging network.

The move ahead of the arrival of the all-electric Mustang Mach-E increases the UK network from almost 3,000 charge points to around 9,500.

Mustang Mach-E drivers will be able to use FordPass to locate, navigate to, monitor and pay for charging at over 6,600 charge points in the UK belonging to the new Pulse network.

Owners will enjoy one year's free access, including a rapidly growing number of high-power 150kW DC chargers, 50kW DC chargers and almost 6,000 7kW AC points.

"The trebling of Ford's network size provides reassurance to offset one of the main concerns about switching to electric – range anxiety," the automaker said.

The Mustang has intelligent range calculations drawing on live data to produce as accurate an available range display as possible, taking into account weather conditions on route affecting capability and information from other Mach-Es.

The inclusion of the Pulse network into FordPass is in addition to 3,000 existing chargers. Also available to Mach-E drivers is one year;s free subscription to Ionity ultra-fast chargers at 15 sites in the UK and five in Ireland.

Ford also offers its Connected Wallbox for all-electric and plug-in hybrid vehicle customers at home – delivering up to five times the charging power of a typical domestic socket.

Mark Harvey, Ford's European enterprise connectivity director, said: "[This] will accelerate our progress towards electrified engines accounting for more than half of our car sales by the end of 2022.

"Key to this roll-out is the supporting infrastructure available to customers, and today's announcement demonstrates our commitment to match more electrified vehicles with enough locations to charge them."

The high-performance Mach-E, arriving this spring, equipped with extended-range battery and all-wheel drive will deliver claimed 0-62mph acceleration in 5.1 seconds and a targeted WLTP pure electric driving range of up to 335 miles. The rear-wheel drive version has a 379-mile WLTP range.
