The South Korean manufacturer SK Signet announced that it will produce ultra-fast EV chargers and power cabinets in Plano, Texas.
The company will redevelop an existing building in Plano as its first US manufacturing facility for electric vehicle fast chargers.
The 136,200-square-foot site will house cutting-edge research & development, manufacture its own proprietary power modules, and conduct charger testing with automakers, which means that it will become a pretty comprehensive hub for the North American market.

SK Signet plans to redevelop an existing building in Plano, Texas, as its first U.S. manufacturing facility for electric vehicle (EV) fast chargers. The image above is a rendering of the expected exterior design.
SK Signet expects that the plant will be operating at full capacity by July 2023, producing more than 10,000 fast chargers per year. By 2026, up to 183 new jobs are to be created.
Regarding chargers, SK Signet is focused on ultra-fast charging units with power output of 350 kW and higher, although its portfolio includes other lower-power units: 50 kW, 100 kW, 150 kW, 200 kW, and 350 kW. Depending on the version, the chargers are single- or dual-head units.
SK Signet says that so far, it has supplied more than 2,500 fast chargers for the US market (out of over 21,000 globally). The company’s 350 kW units were also the first fast chargers to be UL certified, according to the press release.
The list of customers shown on the SK Signet’s website includes major fast charging networks like Electrify America and EVgo.
The latest investment in the US by SK Signet is just one of several made in recent years by the broader SK Group:
Within the EV space, SK companies have made significant investments to support the growth of EVs in the U.S. SK On, a leading EV battery manufacturer, has made a $2.6 billion investment in Georgia for two battery manufacturing facilities. Earlier this year, SK E&S acquired EverCharge, a California-based provider of EV charging solutions, and SK Inc. and SK Energy acquired the management rights of Atom Power, a North Carolina company that’s developed advanced energy delivery systems including EV charging.
