Level 2 EV charging has gained large popularity in the last few years.   The use of level 2 portable EV chargers has grown as electric vehicle owners want to improve their range per charge, get to a full charge quicker and maximize the existing 240 volt charging capability they have at home.  This has been driven by plug-in hybrid vehicles with larger ranges and more pure electric vehicles, which have larger batteries.

Tell me about level 2 ev charging, I keep reading about it…

Level 2 ev charging is basically a more powerful charge to level 1 ev charging.  It is the fastest available charge for your electric vehicle at home.  

Level 2 ev charging costs more, how much more?

Level 2 ev chargers will typically cost $150-$250 more than level 1 ev chargers.   It is typically worth it since you will be able to charge faster and reach a full charge in significantly less time.  This can reduce range anxiety when people drive without a full battery or the need for stopping in the middle of your trip to find a commercial EV charging station.

So I should go with a level 2 charger…

Yes. For most cars, batteries are getting bigger and people are getting busier, so they need more miles of range per hour of charging, quicker. At home, Level 2 ev chargers provide that.

How much faster is level 2 charging

There are some nuances to the speed of level 2 charging since it depends on the type of plug providing the charge.  For example, NEMA 14-50 level 2 ev chargers  and NEMA 6-50 level 2 ev chargers are much faster than  NEMA 14-30 level 2 ev chargers since they deliver more power. In a nutshell, plugs with denominations ending in 50 are rated to deliver up to 50 amps whereas with a 30 they are rated to accept 30 amps, which means less kilowatts per hour are delivered to the battery.  The table below summarizes the mileage impact:

Charge Type Amps/ Voltage Miles of range per hour of charge Setting
            Level 1     12-20 amps  120 V           4-6 miles Residential
            Level 2     20-50 amps  250 V           20-60 miles Residential and Commercial
            Level 3 (DC Fast)     400 to 900 V           60-100 miles Commercial


So how do I check what level 2 ev charging I can run at home

Check at home to see if you have any of the following plug types.  These are all capable of giving your electric vehicle a level 2 electric charge – NEMA 6-20, NEMA 6-30, NEMA 14-30, NEMA L14-30, NEMA 6-10 and NEMA 14-50.   NEMA 10-50 and NEMA 10-30 J1722 ev chargers are unsafe and against electrical code since they are not grounded. 

There are a lot of expensive wall boxes or wall chargers that have level 2 charging. Is that the same as portable (aka mobile electric vehicle charging)  Yes.  Both portable EV chargers and wall chargers are capable of the same chargers since they are limited by the same issue – the power supply availability at home.

When should I consider level 1 instead of level 2 ev charging

We would generally recommend a level 1 charger in a limited set of circumstances:-

  • As a direct replacement for your vehicle manufactured charger (typically supplied with the car)
  • As a second source of charging in case your level 2 power source is being used
  • If you are on a tight budget 
  • If you have a plug-in hybrid with a small battery (<20 kwh). A level 1 charger can charge this in 6-8 hours which is acceptable for most people
  • If you have a car with a battery that has a small acceptance rate.  Acceptance rate is the charging speed that the battery can charge (accept power) at.  Some cars have very small acceptance rates (3.6 kw/per hour).   14-50 and other level 2 ev charger types provide for example 9.6 kWh and 7.2 kWh charges which is wasted since the battery can only accept 3.6 kWh
