Compared to Level 1 and Level 2 EVSE, DC fast chargers typically have cables and connectors that are?

• A. Lighter
• B. The same
• C. Larger and heavier
• D. Shorter

Answer: (C)

DC fast charging delivers high-power DC directly to the vehicle, bypassing the car’s onboard charger. To safely carry that much current, the cables and connectors must be built to handle higher electrical load and run cooler, which means thicker conductors, more robust insulation, and cooling features. This adds bulk and weight to the cable assemblies and connectors. In contrast, Level 1 and Level 2 charging use AC power through the vehicle’s onboard charger with lower current, so the cables are lighter, more flexible, and less bulky. So, DC fast chargers typically have cables and connectors that are larger and heavier.
