How Voltage Affects Ev Charge Rate
Hopefully, those insights and information have already served of great value to you.
Now, lets explain how voltage level and current affect the EV charge rate.
This section touches on the technical fundamentals concerning EV charging time and voltage. Knowing the basic tenets of electrical circuits will be helpful in the upcoming discussion.
It answers the question: Why do DCFC charge the quickest while it takes a Level 1 charger 50-80 hours to charge your EV fully?
Can I Install An Ev Charger At Home
The main thing to know is that electric car chargers are not the same as the outlets you plug your phone and laptop into at home. EV chargers are a completely different type and require special care with installation and use.
Side note: if you arent a rocket scientist, dont worry! We know electronics and engineering terminology can be confusing for many people, so were going to break it all down to make it super easy to understand.
Firstly, power is counted in something called volts. You can think of voltage a little like one of those AA batteries that you put into your TV remote control. When power comes into your outlets at home, its like a ton of batteries all at once.
So, when it comes to electric vehicles, they need a special amount of power. In fact, they need a dedicated power supply of 240 volts of electricity.
If you look at an outlet in your home or office, right now, youll almost definitely see one on top and one on bottom. These standard outlets at home are usually 120 volts each, even though the total power supplied is a full 240 volts. Thats because the top outlet gets 120 volts, and the bottom outlet also gets 120 volts, for a total of 240 volts. Thats really all you need to know in terms of the science stuff. Now, for the answer to the main question: can you install an EV charger at home? The answer is yes.
The Type Of Electric Car
Each company has different tech in their batteries, and each model tends to have different battery pack sizes.
That means that the charging time can vary greatly, even among similar sized cars.
For example, a Chevy Volt will take about 12 hours to fully charge on a 120 volt plug, while a Tesla Model 3 can take between 7 hours and 29 hours, depending on how much power your homes circuitry can handle.

How To Charge An Electric Car
There are several ways to charge an EV, with the most common method being to do it at home, which is what 80 per cent of EV owners around the world do.
In Australia, you can connect your EV to a standard 240V wall socket, but this is the slowest method to charge .
Level 2 is AC charging done using either an at-home wall box charger, or a public AC charging station.
A wall box charger can charge your EV up to three times faster than Level 1 charging, increasing the power coming out of a wall socket from 2.4kW to 7.2kW.
Public AC chargers also typically offer up to 7.2kW, although some go as high as 22kW .
Level 3 is the domain of DC fast chargers / superchargers, which can deliver electricity ranging in power from 25kW to 350kW.
There are more than 3000 public charging stations situated throughout Australia at the moment, with over 470 of those being DC fast chargers.
The Australian Federal Government, as well as several state governments, have all invested funding into EV charging infrastructure, so the number of public chargers is set to continue growing healthily over the years to come.

Electric Car Voltage And Power Requirements
Why do people us 6v batteries in their electric cars and not 12v or 24v? And what are the average power requirements for the average motor that is used in a converted electric vehicle?Hi, Aaron -In DC electric car conversions, with very simple inexpensive controllers, 6v batteries conserve battery power better than higher voltage batteries, so your range ends up being longer with 6v batteries.In AC EV conversions, 12 volt batteries are more common. As for 24 volt batteries, I’ve never seen them.Power requirements? People tend to put at least 120 volt systems in their medium sized cars. As for amp-hours…there’s a trade-off. The more amp-hours a battery has, the longer it can run your car, but the heavier it will be. There’s a sweet spot, generally somewhere around 200 amp hours, that most people use.Regards,
The Power Required To Charge An Ev Depends On Variables
There are many variables to consider and arriving at an optimal answer is complex. The variables include:
To better understand these variables, we discuss each one in more detail below.

Can I Leave My Ev Plugged In Overnight
This is a very common question. Thankfully, the answer is easy and simple: Yes! Yes, you can leave your EV plugged in overnight and charge up the battery.
This is because electric cars have a built-in monitor to stop charging when it reaches its full capacity. In other words, you dont need to worry that youll overcharge or run up your energy bill overnight.
If I Use A Voltage Higher Than 220
Weve touched on level one charging and level 2 charging but there is one level higher than that. Level 3 charging is the expert on getting those batteries to full capacity in no time, and is much faster than 220-volt outlets.
You have probably already seen a level 3 charger. If youve ever seen an electric vehicle charger in a parking lot, those are all level 3. They exceed the 220-volt power outlets in your home by a long shot. You can have your electric car charged to 80% in as fast as 30 minutes depending on the one you have.
These types of chargers are not recommended for home use, as they require a lot of power to charge. The cost of installing one of these is in the tens of thousands. For most people, this will not fit the budget. But this doesnt mean they arent available to you.
As mentioned earlier, these are found in parking lots all across the world and the United States. Some employers even have these installed to encourage more electric car usage or to appeal to clients that own electric cars. This means that you will have opportunities to use these throughout your ownership of an electric car.
Using a charger over 220 volts will be similar to going to a gas station, especially when traveling. There will be times it is busy and you need to wait a while to use one. But, the wait will be worth it when you can pull out on the road in 30 minutes with an 80% charge for only pennies on the dollar.

How Do You Charge An Electric Car
You can charge an electric car by plugging it in to a dedicated socket, called an EV chargepoint. The type of charger and cable needed depends on your vehicle and the type of socket it has. There can be lots of jargon involved with EV charging systems so we’ve tried to break down all the terms you may come across as clearly as possible on this page!
How Long Does It Take To Charge Your Electric Vehicle
Most non-electric vehicle drivers think charging takes forever. However, electricity is everywhere, and some drivers will do the bulk of their charging at home or at work, where their car is able to “fill up” while sitting all day or all night. Also, most non-EV drivers are not aware of DC fast charging where drivers can now typically charge in 15-45 minutes. And when you find an EVgo charger that aligns with your grocery shopping or trip to the park, it only takes a minute or two for you to plug in and tap on the app to start your session, and then the car and the charger do the work while you go run your errand for those 15-45 minutes!
AC Level 1
When a driver plugs their car into a standard wall outlet, thats Level 1 charging. Its the most basic type of charging. And its the slowest. But for people who dont drive a lot each day, and are able to charge at home, Level 1 charging is a convenient way to charge because it doesn’t require installing an AC Level 2 charger.
AC Level 2
Level 2 charging utilizes a 208-240 volt circuit . They charge faster than Level 1 chargers about 5-6 hours instead of 20+ hours. Level 2 chargers are most often found where vehicles are parked for a significant amount of time where charge speed does not matter as much . You can also find Level 2 charging stations in public, such as malls and shopping centers.

The Type Of Charger To Be Used To Charge The Ev
There are three categories of EV chargers these are:
AC Level 1 Chargers Are the Most Basic Level
AC Level 1 chargers are typically units supplied with the vehicle when delivered.
An AC Charger operates as an intelligent switch that communicates with the EVs charging systems to determine how many amps and watts the charger can supply.
Once the system handshake has been completed, and the two systems agree on the variables and have set themselves accordingly, the charger supplies AC power to the EV.
Generally, this level of charging equipment can supply up to 3.7-kilowatt-hours of charge.
AC Level 1 is the slowest way to charge an EV. It adds between 3 and 5 miles of range per hour.
AC Level 2 Can Be Installed in the Home or Office
AC Level 2 systems are much more powerful they need to be professionally installed and provide between 7.4 kw/h and 22 KW/hs of charge.
The larger capacity systems require a three-phase power supply.
When a large charging capacity is available, the limitation tends to be the EVs charging system. Irrespective of the power, most EVs only permit up to a 22kw/h three-phase charge rate.
AC Level 2 chargers can replace between 12 and 80 miles of range per hour, depending on the AC Level 2 chargers power output and the vehicles maximum charge rate.
Level 3 DC Are Known As Superchargers
Level 3 chargers are mainly found at retail service stations or dedicated fast charging facilities and deliver the fastest possible charge rate.
Electric Car Charging At Home
For most owners, 90-95% of all electric car charging will be done at home, either from a domestic powersocket, or more commonly with a specialist electric car charging point.
Charging from a domestic power socket is fine if you are borrowing a power socket when visiting a friendor when staying away from home at a hotel. In North America, where domestic power sockets only provide 110 volts, it can often take 15-16 hours to provide a full charge for your car in this way, but in the rest of the worldwhere 220-240 volts is the norm, you can typically fully charge your car from a domestic power socket in around six to nine hours, depending on which car you drive.
If you are charging your car whilst you are at work, or charging at home overnight, a six to nine hour chargeis ideal: you leave the car plugged in and it is fully charged by the time you need to use your car again.
Most manufacturers recommend that you do not use a domestic power socket for every day charging.Because of the constant high ampage drain, constant charging from a power socket can lead to overheating andthere have been cases where the socket overheats and burns with constant, regular use.
If you live elsewhere, you can arrange for an electric car charging point to be fitted by your car dealer or by contacting your local electrical wholesaler. In the United States, you can buy units from retailers like , Best Buy andHome Depot, or from specialist suppliers like EV Solutionsand NRG eVgo.

Do Electric Cars Need 220 Volts
It is getting easier by the day to obtain an electric car. Charging them is definitely a topic worth researching if you plan on buying one. This is because electric cars need different voltages to charge. But there are many charging options, a lot of which talk about having a charger with 220 volts to charge your car.
But do electric cars need 220 volts? Not all electric cars need 220 volts, but some may. All electric cars are different and each one will require a certain voltage to maintain a charge. In most cases, 110v will perform a slower charge but it will get the job done. 220 volts is needed if you want a faster charge available to you at your home.
While it would make sense to think 110 volts should be enough to charge your electric car, there are many reasons why you would need a 220-volt outlet to charge your electric car. Ive put together some key points on why you would need 220 volts for your electric car.
The Cost To Charge The Ev
As EVs become more common, there is a risk that the national availability of electricity may start to be compromised. Indeed, this is true of poorer countries that already suffer from a constrained electrical grid.
Supply and demand principles may start to rear their head, and the more constrained the national power supply is, the higher the cost of electricity that may be charged.
Already power utilities are offering reduced rates for charging EVs outside of peak hours this has a similar result: increasing the cost as supply drops and demand increases.
More and more home charging stations are being converted to solar power to mitigate these problems.

What Do I Need In My Garage For An Electric Vehicle
You must purchase this part if you want to use the wall-mounted box and the plug that supplies the volts of electricity. An electric vehicle service equipment is referred to as an EVSE in the technical sense. The device enables drivers to connect to a reliable source of electricity without fear of breaking the law.
V Outlets For Electric Car Chargers
The 120v outlet is the standard outlet in any US and Canadian home. Its the same plug that you use for your cell phone chargers, TVs and microwaves.
More importantly, you can also plug in your electric car. This is sometimes called Level 1 charging in your carport or garage.
Charging stations for electric cars should be on their own dedicated circuit, however. If your charging outlet is connected to the same circuit as your laundry room or kitchen, you may draw extra amperage and trip a breaker.
If its not on its own dedicated circuit, we recommend calling an electrician. They can create a separate circuit for charging to ensure that you wont overload your circuits when charging your EV.
Level 1 charging power output can be between 12-16amps of continuous power. That means that the charger can deliver between 3.5 and 6.5 miles of range per hour of charging.
Thats enough to get you around 40 miles of daily driving.

Which Socket Should I Use
The vehicles inlet port and the charger type will determine which socket you use. Rapid chargers use CHAdeMO, CCS or Type 2 connectors. Fast and slow units normally use Type 2, Type 1, Commando or 3-pin plug outlets.
European electric vehicles usually have Type 2 inlets and the CCS rapid standard. Nissan and Mitsubishi manufacturers tend to use a Type 1 connector and CHAdeMO inlet. The Hyundai Ioniq Electric and Toyota Prius Plug-In use Type 2 connectors.
Find The Right Electric Car Charging Station
One of the greatest advantages of owning an electric vehicle is never having to stop at another gas station apart from buying snacks or needing a bathroom break. But unless you’re taking a road trip, you can fill up your electric vehicle every night from the comfort of your own home.
Now, if you don’t live in a place where you can access or install an EV charger, that’s another issue for another article. Here we’re going to give you the rundown on home charging and what sort of setup will suit your needs.

Home Ev Charger Features
Wondering which EV charger type is right for you? Consider the EV charger features below to make sure your selected model will accommodate your vehicle, the space and your preferences.
Features related to your vehicle
Most EVs have the “J plug” which is used for home and level 2 charging. For fast charging, there are two plugs: the CCS used by most manufacturers including BMW, General Motors and Volkswagen, and the “CHAdeMO” used by Mitsubishi and Nissan. Tesla has a proprietary plug, but can use the J plug or “CHAdeMO” with adapters.
Single or dual port
Select charging stations are available with two plugs, some of which allow two vehicles to charge at the same time if theres sufficient electrical capacity.
Features related to your space
Cords are available in a range of lengths, the most common being 5 metres and 7.6 metres . Shorter cables are easier to store but longer cables provide flexibility in the event drivers need to park further from the charger.
Indoor or outdoor
Many chargers are designed to function inside or outside, but not all are. If your charging station needs to be outside, make sure the model you choose is rated to work in the rain, snow, and cold temperatures.
Portable or permanent
Some chargers only need to plug into an outlet while others are designed to be installed on a wall.
