The battery can also be replenished at up to 125kW using DC chargers.
Fleets can choose from 135 or 217hp motor power outputs to suit their needs, each offering 415Nm of torque.
It will be offered as a panel van, with load volumes from 5.8 to 9.0m3, a payload up to 2,425lbs and maximum load length of 3,450mm.
Ford Pro customers can access the brand's Blue Oval Charging Network of more than 300,000 charging points, with every new E-Transit Custom coming with a 12-month complimentary subscription.
The van will be produced by the Ford Otosan joint in Kocaeli, Turkey and production will start in autumn 2023.
Jim Farley, president and CEO at Ford Motor Company, said: "Our customers made Transit Custom the most popular commercial vehicle in Europe, and we've listened to those customers for well over 50 years.
"The new E-Transit Custom was designed and engineered to meet their needs – a Transit for the new era, but one that can still get its hands dirty when a job needs doing."
