  • Understand the type of charger to use before purchase. The chargers are of two types, a level 1 charger and level 2 chargers. A level 1 charger provides ample charging capacity for many electric cars. On the other hand, a level 2 charger is faster and convenient for long-distance drives.  
  • Make sure that your electric system at home can accustom you to the demands of charging an electric car. This includes checking the installation of components like wires, which may increase the likelihood of an electrical fire. You should rectify all damages effectively.
  • If you opted for a level 2 charger, it is advisable to determine whether the home electrical system has a high capacity. If the electrical system is not up to the task, you need to add circuits for the purpose. This will give you the capacity to charge the vehicle.
  • Preserve the parts of your charging station according to the manual or given guidelines. Do not use an E.V. charger with clear signs of damage as this indicates potential hazards.
  • Make sure that the charging station is covered to avoid water from entering. Water spills could lead to fatal accidents and damages. You should check all pipes passing through the stations for any water drips.
  • When purchasing a charging device, ensure it is certified by a recognized laboratory in the country. This will help you use devices that are of quality. It also minimizes the possibility of using obsolete devices for your electric car.

 How to Charge Electric Cars At Home

Having an electric car is advantageous as you can charge it at home. There is no need to stop at a station to service your car. The process of charging these vehicles is fast and reliable. All you have to do is equip yourself with information on how to go about it. Your potential solution could include:

1. Installation of a Wallbox

A wall box is a charging point in the form of a box that is mounted on the wall. It works by connecting it to an electric grid using a circuit. The circuit should be able to carry a large load of power. The wallbox then converts the electricity to the type of current that your battery can hold.

Using a wallbox is advantageous as:

  • They offer optimal safety – a wallbox is equipped with safety features that help avoid electric shock and overheating risks. It also has a diagnostic system that provides high power without posing a risk to the electric system.
  • The wallbox charges faster, taking a shorter time to charge your car. The wallbox provides a higher wattage than a regular outlet. The wattage may range from 3.7Kw to even 22kw. This high power, in turn, makes the wallbox reliable.
  • Using a wallbox is easy. When charging, all you have to do is hook up the charging lead to the car. There is no need to remove the charging cable afterward and put it away again.

2. Using a Three –Pin Plug

The other method of charging your electric car is using a three-pin plug. The slow charger mostly comes along with the vehicle. This type of charging is convenient for emergencies only since it is slow. It works by connecting the three-pin plug to a domestic power supply, which then charges the car.

The three-pin plug is portable and easy to use. It does not require the installation of cables or complex devices. The charger is more suitable for emergency purposes. However, it is not as reliable as using a wall box. 

Many people have inquired on how to charge electric car at home without a garage. You will need to have an electric service and an area to park. Install a hard-wired charging station and attach it to a standing pole or an external wall. Ensure that you choose a charger with a long cord enough to reach the car’s charging port.

When it comes to home charging costs, the most commonly asked question is how much does it cost to charge an electric car at home. The cost of charging an electric car at home will depend on the charging method you are using. You can install an electric car calculator, and it will help you calculate the cost every time you charge the E.V. 

When using the three-pin plug, the cost will be minimal as there are no installation costs incurred. On the other hand, it is more costly to use a wallbox. The wallbox needs installation hence incurring some costs. Generally, the home charging method of electric vehicles is considered to be less expensive.

Questions like how long does it take to charge an electric car at home have been asked by many. The time may vary depending on the size of the battery and the speed of the charging point. For instance, the wallbox takes a minimal time to charge than the three-pin plug.

In some cases, you might need to charge your car while on the road. This brings in the question of how you charge an electric car on the road. To charge your electric car on the road, it is advisable to download an Electric Car charger app. The app gives you information on alternative fuel locations around where you are.

 It also helps the drivers to plan trips that are within available chargers. The mobile app can also connect the chargers to the drivers while they are on the roads. These apps include ChargeHub, PlugShare and in some cases, the cars have an in-built navigation system.

Home Charging Station

The home charging station includes the level 1 and the level 2 charging stations. All-electric vehicles come with a level 1 charger which is portable. You can plug these chargers into household outlets. They do not require any specific installation. Cars like Tesla come with level 1 and 2 chargers.

The level 2 charger, on the other hand, charges the E.V. faster. Many people opt to buy a charging station that delivers more power than their electric cars can accept. This ensures that they are ready if their next electric car charges at a high rate. Therefore, they tend to use the level 2 charging station. 

Factors to Consider When Choosing a Charging Station

When looking for a charging station or designing a home charging station, you need to be very careful since the well-being of your vehicle depends on it. Some factors to be keen on are:

1. Power

Level 2 charging stations provide a large capacity of powers ranging from 16 to 80 amps. This accelerates the speed of charging your electric vehicle. This type of station is preferred as it helps avoid the hustle of finding an expensive high-powered station later. A charging station that gives at least 32 amps is more preferable.

2. Cable length

A preferable cable length that you are advised to use is at least 20 feet. This helps suit your needs conveniently. You can also opt for a length of 24 to 25 feet in length. The longer the length, the more suitable it is.

3. Safety certified

Due to the increased use of electric cars, there has been a rise in companies making E.V. chargers. Some of these companies are not following the right measures of certifying the safety of the device. This may lead to car damages and is also not safe for people. It is therefore advisable to use certified chargers.

4. Cost

Having a charging system that costs more does not necessarily mean it is the best choice or quality. A charging station that is less expensive, has an amicable warranty, and is built well is the quality one. When looking for a charging system, look for the ones with discounts and special offers also.

To calculate the charging cost, use a cost to charge electric car calculator. You will first select the vehicle you are using and enter the power rating of your home charger. Enter the home electricity cost. This will show your cost per mile for your home charge and the total cost as well.

If you want to charge your vehicle cheaply, look for the free car charging points near me. Some places to charge for free are public parking garages, some urban street corners, and retail parking lots. The use of mobile apps like plug share could also help get to these places.
