Frequently Asked Questions

There are many different terms and buzz words used in EV charging.   For example, you may see articles on level 1 charging, level 2 and level 3 charging or AC/DC fast charging.   The industry is complex, and our mission is to make things simpler so you can get the EV charging solution that meets your needs. We cut through the jargon!

In a nutshell, it is really the fastest available charging at home.   Tesla uses 40 amp level 2 charging and since then it has become the gold standard in fast charging or level 2 charging.    40 amp (current) produces a high output (kilowatts per hour), which will charge or “fill” your battery more quickly.   A 40 amp level 2 charger will power up your battery 3 to 4 times faster depending on the size of your battery and how much charge it can receive (some batteries have a slower charging rate due to limits on their power acceptance).   Level 1 EV charging on the other hand is much slower.

This standard provides a charge of ~ 9.5 kilowatts.  As batteries get bigger, this provides a larger kilowatt per hour charge and also suits well the amount of power that electric vehicles on board charger can accept.    A few additional reasons in the U.S. has enabled this: –

  1. 40 amp level 2 charging has gained more traction in recent years due to improvements in technology and bigger batteries. 40 amp level 2 provides the benefit of faster charging.  Technology improvements have allowed for more powerful level 2 charging.   Five or so years ago it was more common to find lower power level two chargers such as 24 amp or 32 amp.  As technology improved, higher power 40 amp level 2 chargers become more available    
  2. Many homes, especially newer ones, had existing 240-volt outlets.  These were being used for power tools, ovens, dryers and washing machines.  The industry adapted EV chargers to create 40 amp level 2 chargers to suit existing residential outlets
  3. The circuit breakers on residential panels had a 50 amp current rating to suit 240 volt charging.  This allowed for plug-in residential ev charging set up which uses as 50 amp, 240 outlet, which safely enables a 40 amp level 2 charger.

This is because electrical standards designate that that a circuit is equal to 125% of an electrical device/instrument’s continuous load.  This means only 40 amps should be used on a 50 amp circuit

Some newer, higher performance pure electric vehicles now have 11-KW on board chargers (this is the amount of power the charger can accept each hour).  A 48 amp level 2 charge is possible but requires electrical work to have an electrician hardwire the device directly in the circuit.  This is often overkill, is expensive and there is no ability to plug/unplug your EV charger for portable charging or if you move house.

There are two reasons:-

  1. Some homes will have a 60 amp (instead of a 50 amp) rated plug and/or circuit breaker slots on which you may run a 50 amp EV charger.  Some hot tubs run on 60 amp breaker circuits to suit higher amperage, high capacity hot tub model.  Generally, the amps should be 80-85% of the circuit break rating (60 amps*80%=50 amps).  This avoids overloading the breaker and tripping the circuit, so a 50 amp charge may be possible if you have a 60 amp slot on your circuit break on your electrical panel.
  2. Third party sellers are selling 48amp and 50 amp level 2 chargers and are encouraging their use with for example NEMA 10-50, NEMA 6-50 or NEMA 14-50 plug receptables.    This is against electrical standard and potentially local code since the amperage should be 80-85% (that the EV charger pulls) of the circuit breaker rating.  At this rating, you may experience a lot of breaker trips, which is an inconvenience and may pose a safety hazard.

We recommend our NEMA 14-50 level 2 and NEMA 6-50 40 amp level 2 EV chargers.  40 amp level 2 chargers will generally charge your car more quickly.  This can reduce range anxiety (if you need a full charge quickly to give you maximum range) and allow you to complete your EV charge in a shorter period of time such as overnight when electricity is cheaper.  A 40 amp level 2 charger will also futureproof you as batteries get bigger and can accept more charge.  It will charge your current car as fast as it can accept and charge your next car faster.

Yes.  Level 2 EV charging is considered as any charge more powerful than level 1 12 amp or level 1 16 amp (120 volt) charges.   The type and speed of level 2 charging will depend on the EV charger plug type.

Table comparison of Level 1 v Level 2 EV Charger charge times

 

Charging Level Plug Types Miles per hour of charging* Approximate charge time to full battery
Level 1 Charging

(regular home 3 pin)

NEMA 5-15

NEMA 5-20

2 to 3 miles  8-24 hours

(Depends on size of battery)

Level 2 Charging   

(20-30 amp plug)

NEMA 6-20

NEMA 6-30

NEMA-10-30*

NEMA 14-30

NEMA L14-30

5-15 miles 6-20 hours

(Depends on size of battery)

Level 2 Charging            

(50 amp plug, 40 amp charge)

NEMA 14-50

NEMA 6-50

NEMA 10-50*

Up to 30 miles 3-12 hours

(Depends on size of battery)

 

The continued use of NEMA 10-50 and 10-30 plugs is dangerous.  If you have either a NEMA 10-50 or 10-30 plug we strongly recommend finding a licensed electrician in your area to change these plug outlets to grounded type outlets.  Both NEMA 10-50 and NEMA 10-30  are non grounded plugs i.e. hot hot neutral and are missing the critical ground conductor.
