A professional job typically signifies that someone is in the highest-level position in his profession, or has the potential for upward mobility with experience. A non-professional job usually means that you perform front-line or lowest-level duties in an industry or company. Laborer jobs and front-line sales and service jobs in retail are listed as examples of non-professional jobs on the University of Illinois website.
The J1772 plug was specifically designed for electric car charging. Problem is, given a typical electric car like the Nissan Leaf, it can take 15 hours to charge the battery from empty to its EPA-rated 75-mile range from that standard household source. Most plug-in cars have a J1772 port, letting them plug into public charging stations.
Scott Briasco, of the Los Angeles Department of Water and Powerâs EV program, said that more than half of the 20,000 plug-in EVs in the utilityâs service area are charging this way. It isnât fast. Most cars charge at the rate of about 4 to 5 miles of range per hour. So, a mid-range vehicle like the Chevy Volt, with an all-electric range of 50 miles or so, will take 10 hours to completely recharge its battery. This kind of charging is relatively inexpensive and requires no special equipment.
