Electric Vehicle Charging at 220/240 Volts From 110/120V Outlets

Nissan Leaf, Toyota Plug-in-Prius / Rav4 EV, Mitsubishi i-MiEV, Chevy Volt / Opel Ampera, Honda Fit EV, Ford Focus EV/C-Max, or any J-1772 compatible EV or Plug-in-Hybrid

Situation: Charging electric vehicles with 110/120 volts is very slow. EV owners at times find themselves in situations where they can't install a charge station or there is no 220/240 volt outlet available, but still need a faster charge.

Solution: Nissan Leaf owner Curran cuts his charge time by a factor of 3 using a Quick 220® system in conjunction with the EVSE Upgrade modification to the charging cable. We thank Curran for sharing this YouTube video with us.

Electric vehicles are becoming increasingly popular as drivers become more environmentally conscious. With rising gas prices, electric vehicles also alleviate this burdensome expense. The Nissan Leaf is one of the most popular electric vehicles, but you can be caught in a sticky situation if you’re in an area you don’t know and you don’t have a way to quickly charge your vehicle. However, one of our customers with a Nissan Leaf purchased a Quick 220® Systems converter to do his electric vehicle charging at 220/240 Volts from a 110/120V outlet, and was pleased with the result.

Charging an electric vehicle at 110/120 Volts is a long and difficult process. Whether you have to make an extended journey or a quick trip out, if your vehicle takes too long to charge, it’ll render you immobile.

That’s where the Quick 220® Systems come in to help. The Quick 220® Systems voltage converter makes it a breeze to do electric vehicle charging at 220/240 Volts from 110/120V outlets. Your vehicle will charge faster, making it easy for you to get around in your electric vehicle.

One of our customers shared his positive experience using the Quick 220® system as a Nissan Leaf 220V charger, and even made a YouTube video to show how to use it and the benefits of a Quick 220® charger. If you’re curious about some of the technicalities of our product when used as an electric vehicle charger, check some of our frequently asked questions below to find you answer.

Answers to Questions Raised in Discussion Groups

  1. 1. Safety and Certification. The Quick 220® Power Supplies meet the fire and safety standards of UL (Underwriters Laboratories), CSA (Canadian Standards Association), and OSHA (United States Department of Labor, Occupational Safety and Health Administration.)
    1. A. UL and CSA publish product safety and testing standards for use in the United States and Canada. Quick 220® Power Supplies conform to UL Standard for Safety Power Units (UL1012) and to CSA Standard for General Use Power Supplies (CAN/CSA C22.2 No. 107.1.)
    2. B. Qualification of testing laboratories in the US is under OSHA, which recognizes about 15 labs to test products. Intertek Testing Services, an OSHA recognized lab, tested and certified the Quick 220® Power Supplies to both UL and CSA standards. Additionally, Quick 220® Systems is inspected quarterly by Intertek to assure continuing compliance with the standards. Quick 220® Power Supplies are listed In the Directory of Intertek Certified Products and bear the Intertek "Listed" Certification Mark for both the US and Canada.
    3. C. UL, CSA, OSHA, and the Nationally Recognized Testing Laboratories concern themselves with the safety of products that are brought into the home or business. The NEC (National Electrical Code) addresses the permanent wiring of buildings and other facilities. In general, if it is in the walls or a permanent part of the facility, NEC defines how to do it safely. If you can plug it in, then UL, CSA, OSHA and the testing laboratories address product safety.
  2. 2. Quick 220® Functions. Some of the contributors to the discussion were uncertain about the operation of the Quick 220® Power Supply. Here is a summary.
    1. A. A double pole circuit breaker is mounted in the side of the case, recessed to prevent accidental on/off switching. It is either a 15 or 20 ampere breaker, depending on the model Quick 220® Power Supply chosen. The breaker protects the vehicle, the Quick 220® Power Supply, and the building wiring. Incidentally, the branch circuit breakers in the building perform the same functions at a different level. When extension cords are used, the user should use electrical cords of appropriate gauge for the ampere load. This is detailed in the instructions.
    2. B. The Quick 220® Power Supply has internal safety interlocks that function as follows:
      1. a. No power is available at the 240 volt outlet until BOTH 120 volt power cords are plugged into 120 volt outlets that are electrically out of phase. Should one of the 120 volt power cords lose power or become disconnected, ALL power is immediately cut off from 240 volt outlet. This protects the user and the vehicle from the effects of the vehicle receiving the wrong voltage by mistake or circumstance.
      2. b. Until a 120 volt power cord is connected to a 120 volt electrical source, it is electrically isolated from the electrical circuits of the Quick 220® Power Supply. This protects the user from accidental shock through the exposed plug contacts.
      3. c. Should one of the 120 volt supply outlets be wired incorrectly and have the hot and neutral lines reversed, the Quick 220® Power Supply prevents any electricity from being connected to the 240 volt outlet. This is to prevent damage to the vehicle and any other consequences of low voltage.
    3. C. Ground Fault Circuit Interrupters (GFCI or GFI) . A Quick 220® Power Supply will trip GFCI’s, which are typically found in wet areas, such as kitchens and bathrooms. One should select electrical circuits in areas of the building that do not have GFCI’s. An outlet tester is supplied with every Quick 220® Power Supply that will quickly identify GFCI controlled outlets.
    4. D. Find the out-of-phase 120 volt circuit. Connect the first power cord of the Quick 220® Power Supply to a convenient 120 volt outlet. Then, test different outlets with the second power cord until the amber light on the front panel illuminates; plug in the second power cord. Begin using the 208/240 volt outlet of the Quick 220® Power Supply. About half the outlets in a building will be out-of-phase.

To charge Electric Vehicles with 220/240 volts using a Quick 220® system, the following items are recommended:

  1. Quick 220<sup>®</sup> A220-20L with NEMA L6-20 Locking Receptacle1. Modify charging cord to Level 2 capability. Contact EVSE Upgrade ( for this service.
  2. 2. Quick 220® Model A220-20L. Since the vehicle location and 120 volt outlet locations will vary, the Quick 220® Model A220-20L with locking receptacle comes in 3 options that have different length 120 volt power cords for various situations. They are listed below and are linked to more detail in our catalog section.

  1. Option 1: P-108(includes Model A220-20L plus two 20 ampere, 120 volt extension cords and two adapter cords)
  2. Option 2: P-102 (includes Model A220-20L plus one 20 ampere, 120 volt extension cord and two adapter cords)
  3. Option 3: P-103 (includes Model A220-20L plus 2 adapter cords)

Operational Note: Newer model charging cords have the option of vehicle charging at about 16 amperes. The recommended Quick 220® packages will support these higher charging rates if connected to 20 ampere building circuits. However, if the Quick 220® system is connected to 120 volt circuits which have 15 ampere circuit breakers, one will probably trip those 15 amp breakers. If this happens, the module in the charging cord can be set to a lower charge rate that will not trip the building circuit breakers. If there are questions about setting the ampere charge rate, check your EVSE Upgrade instructions.
