Shares of Tesla jumped nearly 7% following a partnership between General Motors (GM) and Ford to use Tesla's electric-vehicle charging network, which could make Tesla Superchargers a new industry standard in the US. This move ensures that the country's EV market can access Tesla's North American Charging Standard (NACS), which presents a big win for the rare partnership, making it the primary network in the country. The tie-up will increase the pressure on other automakers to upgrade their networks to work with Tesla's. Tesla's charging network is more widespread and reliable than the alternative combined charging system.
