That largely depends on the type of charging system.
- Level 1 can take over 24 hours to charge.
- Level 2 is the most popular system for residential and takes about 6-12 hours for a full charge depending upon the vehicle and charging Ampacity.
- Level 3 can charge your batteries to 80% in as little as 11 minutes, but this is only for commercial use due to the power required.
To get a 40 amp charge rate you’re going to require a 50 amp breaker. The reason for this is that breakers are only rated for 80% of their capacity as a safety mechanism. Below are the ampacity rates for their respective Breaker.
- 15A Breaker = 12A Charge Rate
- 20A = 16A Charge Rate
- 30A = 24A Charge Rate
- 40A = 32A Charge Rate
- 50A = 40A Charge Rate
- 60A = 48A Charge Rate
Yes and No. The actual Receptacle Is the same, they both use a NEMA 14-50R receptacle but the electrical system for an EV and a Range are extremally different. Using a range electrical system for an EV receptacle has a very high chance of causing a fire and will not pass inspection.
Most plugs (or nozzles) which are the end inserted into the vehicle, are the same for North America. Most EVs sold in North America (Mitsubishi being the exception) use the same standard Level 2 charging plug called an SAE J1772 (IEC Type 1), also known as a J plug. This means you can charge any electric vehicle at any standard Level 2 charging station in North America. As for level 3 chargers, North American EVs use an SAE CCS1 combo plug, not every EV can charge at level 3 chargers. You’ll need to check your vehicle specifications. The last connector is the one used by Teslas. That connector is used for level 2 and 3 Tesla Supercharging stations and is only compatible with Tesla cars.
If you have chosen to go with a larger ampacity charger, then it is very likely that you will exceed your house’s load calculation. The first solution is to upgrade your panel to accommodate the EV Charger, this can be expensive though. Fortunately, there is a better solution to this problem, a product called Black Box. Black Box is a power management system that monitors your service and turns off the charger if the main service is becoming overloaded. Black Box will automatically turn the charger back on when the service is able to handle the ampacity again meaning you never have to worry.
There are 3 different Levels of chargers. The first is level 1 and uses 120 volts and is what your standard Home receptacle would use. Level 2 uses 208-240 volts which is the most common level for both residential and commercial applications. Level 3 uses voltages above 240 and is only applicable to commercial applications. Refer to our posts section for more details.
A load calculation is a formula that electricians use to make sure that the service provided is sized correctly to handle the loads your house demands. This calculation has to take into account all electrical loads that are available in your house. EV chargers are a very high demanding load and affect the load calculation dramatically. By adding an EV charger you may exceed the load calculation causing the electrical inspection to fail, so it is always important to do the load calculation before starting any work. If someone were to ignore the calculation and install the EV charger anyways, the main electrical panel disconnect would trip leaving the entire house without power.
- Getting the required information about your home so we can determine what will be involved in your installation. This will include the charging location, service of your panel, is there space in your panel for the chargers breaker, and what size breaker would you want, as this will affect the charge rate. Information like this is necessary to provide you with the right electrical system for your charger.
- Choosing whether you would like a receptacle or a Specific EV Wall charger installed. Most major brands sell wall chargers that they suggest but these are not a necessity to charge your vehicle. Though they do add some more functionality, you can get a NEMA 14-50R Receptacle installed instead to save on some cost.
- Once you have chosen which electrical system you would like installed, we schedule a date that works for you and get your Charging system installed hassle-free. We provide the permit and pay for the inspection fee but it will be up to you to contact the local inspection agency and allow them to complete their inspection of the new charger electrical system. This inspection is mandatory and is required by law.
