BP enters U.S. EV charging services market

• It's also part of oil majors' wider diversification into renewables, hydrogen, charging, batteries and other areas outside their core oil-and-gas businesses.

How it works: Amply helps fleets manage and optimize charging at a time when corporations, cities and others are increasingly looking to electric delivery vans, buses, trucks and cars.

• The offerings include "charging as a service," in which Amply helps with areas like hardware procurement, software and maintenance issues.

Catch up fast: BP has made a series of acquisitions and investments in the charging hardware and tech space, such as its 2018 purchase of U.K. provider Chargemaster.
