If you are planning to buy an EV, possibly you are quite conscious about the lack of charging facilities for electric vehicles in our country. As you know, there are not many efficient EV charging stations available in our country. Which is why most EV owners prefer charging electric cars at home.
How to charge your electric at home is one of the major concerns of most EV owners. But, charging them at your home is much simpler and easier than you think. Also, due to the advanced facilities, and technologies it is getting even easier.
Now, there might be so many questions which are coming in your mind including where to start from? Do you need to get the installation of the home charger done first? What are the charging options? The exact cost of installing a charging station? What is the process? etc. No need to worry, every important thing about charging your electric car at home is explained below just for you.
Why do you need a dedicated charging point at home?
You must have an e-car charging point installed in your parking area, to charge your e-car. You can also use your usual 3 pin plug sockets as a back-up. However, here are some points to consider for a dedicated charging system.
The process of installing a home charger
The installation process of home chargers is typically done by professionals.
Typically, the cost of installing an electric charging station at your home is based upon your required charging speed, and on any cool features you want from your home electric charger. You can charge your e-car with your usual AC charger socket, which is 3 kWh, but it will be too slow.
There are also smart unit chargers available, which are wireless chargers and can be controlled via just a smartphone app. Few manufacturers are now offering free home installation of wall box chargers.
What is a slow electric charger?
A slow charger is typically our normal household 3 pin plug-in plug. This is just 3 kWh, which is good to charge EVs, but it may take around 24 hours or longer. Whereas, a good fast charging requires at least 7 kWh.
What is a fast charger?
Basically, a fast charger is a wall box, which can connect with various apps on your smartphone via Wi-Fi or Bluetooth. This charging system will help you to control the charging schedule of your car, and it also gives you the facility to decide how much electricity you should put on the EV. Therefore, you will be able to control the amount of energy in the battery to 80 percent, this will help to restrict overheating of cells and boost the longevity of the battery.
For these reasons, one may say that smart chargers are more expensive than the standard units. However, government subsidies are applied on these types of equipment as well. As a result, in some situations, these might be cheaper to buy.
What is a DC fast charger?
DC fast chargers are the best when it comes to speed charging your EV. They can operate from the rate within 43 kWh to 150 kWh. Typically, these rapid chargers at 50 kWh. These units can operate with both direct current (DC) and alternative current (AC). With these units, even the large batteries can be fully charged within as little as 20 mins.
If you are planning for long road journeys, then these chargers are the best charging options. However, not all cars cannot adapt to this amount of charge. So, do check what amount of charge your EV is capable of accepting.
What wattage of wall charger should you buy?
The power your charger can supply will be formed on both of your home wiring and your car’s charging adapter. 3 kWh is the lowest available, which is a very slow charger with this a modest 40 kWh battery will take 12 hours to juice up, and larger models might require 24 hours for full charge.
Maximum wall charger provides 7 kWh fast charging. This 7 kWh will juice up the battery within the half-time of what a 3 kWh would take. And the best part of this is, your car will be fully charged overnight. There are also 11 kWh and 22 kWh options available.
How fast can you charge your e-car at home?
Mostly, a 7 kWh wall box is the fastest way of charging your e-car at home. With this 7 kWh, your e-car will be fully charged within 60 to six hours. However, the charging time depends on the car’s battery capacity.
You will need to upgrade your wiring into a three-phase system for even fast charging, this will enable 22 kWh charging. With the 22 kWh fast charging, a Hyundai Kona Electric would take just 1 and half hours to fully charge.
What is the cost of installing a charging station at home?
The battery capacity of the latest e-car range starts from 20 to 45 kWh. Typically, 15 units of electricity will be exhausted to juice up your e-car. The cost also depends on the power rate in your state, which may be Rs. 6 to 10 per unit. For example, in Delhi, the domestic rate is Rs. 3 to 8 per unit. In that case, to charge your vehicle, you will need to pay around Rs. 150 to 450, which will serve you 200 to 300 km depending on the driving range of your car.
The initial cost of establishing a charging station in your house can cost from Rs. 3000 up to 2 lakh. This is the approximate cost, which depends on the type of the charger and other additional costs associated with the installation. Charging electric vehicles at your home might put an additional load on your electric supply. Based on the maximum charging rate of your car and charger point, this additional load might damage your main fuse. To prevent the overloading, you can definitely go for smart wall chargers. As they are very efficient and have the ability to control the power.
So, those are all the crucial factors that you should know before charging your e-car at home. Hope this article has helped you to understand everything about electric cars chargers.
