Electric Vehicle Charging Tesla

Situation: Charging a Tesla electric vehicle with 120 volts is very slow.

Solution: Eric uses the 240 volt output of the Quick 220 Power Supply to get 3 fold faster charge when he is away from his home charging station.

"This 120 Doubler rig solves a problem and I use it every day.

Not everyone can access a 240V circuit no matter how much they desire. "Fast" is a relative term but I assure you, those that are still forced to 120V sites will take notice.

This device is useful for Tesla owners living, (or visiting) apartment buildings and condos. For road trips it can significantly cut wait times at charge stops.

With 120V at 12 amps I get about 3.5 Miles Per Hour Charge (MPHC) (the Tesla charge manual lists that as a from-empty 70 hour charge) Very slow because the temperature control pumps and fans consistently draw power first.

With 120V and the VDS set to 16 amps I get about 4.8 MPHC, (the Tesla charge manual lists that as a from-empty 36 hour charge) a huge difference.

With the 120Doubler rig at 16 amps, charge time is now 11 MPHC (the Tesla charge manual lists that as a from-empty 18 hour charge) Any increase of amperage from this point show much smaller gains in charge time. With this setup, charging is basically overnight!

It consists of:
A MC240 or Roadster Foundry cable
A Quick 220
Various Adapters (user wired)
Long heavy duty extension cord(s) to find an out of phase 120V circuit. Mine is 130 feet

The image shows the setup outdoors but this is an indoor rated device. Also note the coiled cord shown is an unsafe practice and no power is present in the picture."

Note: The white box below the drivers door is the Quick 220 system.

Answers to Questions Raised in Discussion

  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 GFCIs, 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 GFCIs. 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.
