The No. 1 U.S. automaker said it had signed agreements with seven companies including Blink Charging, ChargePoint and EV Connect.
"EV customers will soon be able to easily see real-time information from nearly 60,000 charging plugs...find stations along a route and initiate and pay for charging," GM said in a statement.
The automaker also introduced "Ultium Charge 360", a platform which integrates charging networks, GM vehicle mobile apps and other services to simplify the charging experience for its electric-vehicle owners.
GM's next generation of Ultium batteries will be used in its new EVs including the Hummer EV and the Cadillac Lyriq.
Wall Street has been increasingly focusing on GM's strategy to roll out electric vehicles, as it slowly aims to catch up with EV market leader Tesla Inc.
The automaker previously announced a $27 billion investment in EV and autonomous vehicles (AV) through 2025 and the launch of 30 new EVs by 2025-end.
GM's longer-range target also includes halting sales of light-duty gasoline and diesel-powered vehicles by 2035.
