In a recent LinkedIn post, General Motors Chairman and CEO Mary Barra confirmed her company’s research and development of a 10-minute EV charger with Delta Electronics.
GMAuthority has previously reported on this story, but the automaker has now publicly confirmed it. GM is investing in more electric research and development.
Part of a new U.S. Department of Energy initiative, GM claims that it will deliver a “prototype vehicle” capable of a 180-mile range all while requiring less than 10 minutes of charging, which encroaches on the convenience of gasoline fueling stations. The prototype will be sent to Delta Electronics for official testing.
Other project partners include DTE Energy in Detroit, Virginia Tech’s Center for Power Electronics Systems (CPES), solar window producer NextEnergy, the Energy Office at the Michigan Agency for Energy, and Detroit’s Office of Sustainability.
To complete this 10-minute EV charger project, solid-state transformers (SSTs) and a high-voltage direct current (HVDC) port will be used to deliver 400 kW of power. The projected grid-to-vehicle efficiency will be 96.5 percent, which is a 3.5 percent improvement over current technologies.
Additionally, the new system is expected to be half the size and about a quarter of the weight than a conventional DC fast EV charger (DCFC).
One of the reasons GM is developing this “extreme fast EV charger” is due to customer concerns. According to the automaker, its customers want shorter charging times. With charging stations scarce across the U.S. and a plethora of different charging standards, driving electric vehicles becomes cumbersome. Having a wider range with less required charging time makes driving easier.
GM states that it is “bolstering EV development, partnering with utilities, states, and others to build a robust infrastructure.” Globally, GM plans for an electrified future and is laying down the infrastructure to make it possible, all while being at the forefront of this transition.
GM plans to launch 20 new all-electric vehicles globally by 2023. Capabilities of handling the forces of a 10-minute EV charger would certainly make these vehicles more appealing.
