AC vs. DC Power: What's the Difference for Electric Vehicles?

EV Connect

Electric vehicle charging stations use both alternating current (AC) and direct current (DC) to power EVs. AC vs. DC Power Near the turn of the 20th century, Thomas Edison and Nikola Tesla were developing the types of electric power we use today. Tesla established AC electricity to combat some of the obstacles DC presented.

ANSI releases for public comment draft roadmap of standards and codes for EVs at scale

Green Car Congress

The roadmap’s primary focus is on light duty, on-road plug-in electric vehicles (PEVs) that are recharged via a connection to the electrical grid, as well as the supporting charging infrastructure needed to power them. Topics covered include standards to address high power DC charging; storage (i.e.,

2025 Ram 1500 Ramcharger: Charge It Up

The Truth About Cars

There is apparently no mechanical connection between the V6 and the wheels. A power inverter module connects to a junction box. Ram says customers can gain 50 miles of range in 10 minutes via 400-volt DC fast charging at up to 145 kW. The Pentastar V6 is changed so that the onboard generator can mount directly to it.

DSM expands CTI test lab to support high-voltage testing up to 1500 VAC and 1000 VDC for EV makers

Green Car Congress

DSM Engineering Materials has expanded its Comparative Tracking Index (CTI) test laboratory with equipment to validate tracking resistance to voltages up to 1,500V AC and 1,000V DC. Tracking refers to the breakdown of the insulation material that exists between conductive surface elements.

“Charging Station” — Is That the Location or the “Charger”?

EV Adoption

This requires simple, easy-to-understand terms without jargon, and that leverage consumer’s existing reference point of the gasoline refueling experience. In an ensuing discussion around this “charging station” reference it wasn’t clear what the author meant. 39% assumed charging station refers to the site/location and 43.2%

Ideal Power, developer of new indirect power conversion technology, prices IPO

Green Car Congress

Since the input and output are never directly connected together, this novel current modulation technique provides circuit isolation without the size, weight, cost, and efficiency loss of a transformer. The system is designed to allow power to flow in any mix among any ports with 96.5% estimated CEC efficiency.
