Level 1 Workplace Charging – Dept. of Energy Report


A report on Level 1 (120 volt) EV charging at work has just been published by the US Department of Energy. The 20 page report covers two scenarios for providing Level 1 EV charging at workplaces. Scenario A is making a 120 volt outlet available for employees to plug their own charging equipment into. Scenario B is the workplace providing Level 1 charging equipment with a J-1772 connector for employee use.

Level 1 charging is capable of replenishing between 30 and 40 miles of range while connected for an 8 hour workday. Over 90% of employees in the US commute less than 35 miles.


The report suggests policies that employers can put in place to help ensure the success of a workplace charging program. Fee structures to recover the cost of Level 1 charging are also suggested.

The experiences of several Department of Energy Workplace Charging Challenge partners, including Coca-Cola in Atlanta and Melink in Milford, Ohio, are shared.

A PDF of the report can be downloaded at the Dept. of Energy website: L1 Charging At The Workplace.

CHAdeMO Connector Instruction Video

Using the CHAdeMO connectors on some DC Fast Chargers can be a challenge. There are buttons to press and levers to pull and release and they have to be done in the right order. Here is a short video by Yazaki that shows how to operate this kind of CHAdeMO connector.

Tip: Beware of Buggy Charging Stations


Look for Bugs Before Plugging In

Is there a spider weaving a nest inside the EV charging connector that you’re about to plug in to your car? Or maybe a little grasshopper is seeking shelter between the pins of the J-1772 assembly.

Now that summer is here and insects are out, take a quick glance inside the connector of any public charging station before you push it onto the receptacle on your car. You don’t want any big insects to get mashed inside your car’s charging inlet port.

Check the Gasket

In addition to bugs and spider nests, check for other dirt or debris and make sure the gasket inside (the green ring in the photo above) is not coming loose.

Hope this tip is helpful. Charge on!
