US: DC Chargers Characterize 21.5% Of All Public Stalls

The general public charging infrastructure in america steadily expands and within the first quarter of 2023, surpassed 140,000 particular person ports (or stalls) – AC or DC. That is nearly two occasions greater than in This autumn 2019 when there have been greater than 70,000 charging ports out there.

The Division of Vitality (DOE)’s Automobile Applied sciences Workplace studies that greater than a fifth of all publicly out there charging factors occurs to be DC quick chargers. In Q1, the share of DC ports amounted to 21.5 %.

Nearly all of public charging factors are in fact the AC Stage 2 models (240 volts), whereas the AC Stage 1 models (120 volts) signify a marginal portion of the market.

It is price noting that the growth of DC quick charging infrastructure is noticeably quicker than AC charging infrastructure in nearly all quarters, over the previous 3+ years. We assume that the DC charging factors are merely extra wanted to spice up automotive electrification on the present stage.

The DC chargers normally supply energy output between 50 to 350 kilowatts (kW), though the vast majority of new chargers are most likely within the 250-350-kW vary.

Within the case of the AC charging factors, they’re usually 7-12 kilowatts (as much as 19.2 kW in some circumstances).


In the meantime, when together with personal charging factors (put in at workplaces or for industrial/fleet use), the full quantity is at present above 160,000 (161,562 as of Q1 2023).

On prime of that, comes tens of millions of dwelling charging factors, that are the principle charging answer for electrical car homeowners. They’re normally used for in a single day charging.


  • Percentages in determine signify the % development between every quarter.
  • Contains public charging ports that may very well be recognized by stage. Charging ports are the variety of retailers out there to cost a car (i.e., the variety of automobiles that may concurrently cost at a charging station).
