ARTICLE 625ELECTRIC VEHICLE CHARGINGSYSTEMS
HISTORY OF ARTICLE 625ELECTRIC VEHICLE CHARGINGSYSTEMSArticle 625 was entered into the NEC in 1996,covers the charging equipment external to thevehicle. It covers anything installed with eitherfeeders or branch circuits to charge the vehicle625.1 Scope. The provisions of this article cover the electricalconductors and equipment external to an electric vehicle thatconnect an electric vehicle to a supply of electricity by conductiveor inductive means, and the installation of equipment and devicesrelated to electric vehicle charging.

TESLA CHARGING STATIONSThe stations--faster than any othercharging stations in existence,according to Tesla--can provide up to100 kW (in the future, up to 120 kW)of power to EVs, juicing them up in 30minutes with enough power to drivefor three hours.
TESLA SIt’s no five-minutetrip to the gasstation, but we aregetting closer.Tesla’ssuperchargers offerpower for free forall Tesla S.

CHARGING IN 30 MINUTESSupercharging past thehalfway point slows downconsiderably. This is due to thebattery technology. The morefull the cells become, theslower the charging has to be,because charging is too fast,the cells become damaged.
