Charging an electric vehicle today in the world has become simpler when it can be charged at home, at work or at a public charging station. However, for many people, especially Vietnamese customers, electric cars are still a new thing.

How to charge an electric car

Recharging an electric vehicle battery just got easier, even when you’re using it for daily commutes or weekend trips. However, you still have to prepare a detailed charging plan, ensuring enough battery capacity to move, compared to running a car using an internal combustion engine.

For example, in the UK, if you use a Tesla, the Supercharger charging system has 800 locations, spanning highways to shopping centers and hotels. Car owners can easily search for charging points thanks to applications installed on smartphones, or on the charging point finder feature in the vehicle application.

Public charging stations also provide many payment functions, such as payment cards or internet banking instead of having to use cash. So where and when to charge depends on how and where you are driving. However, electric vehicle users often choose to charge their batteries at home overnight, and using public charging stations is often when you have a long range to travel.

How long does it take to charge an electric car?

The answer to how long it takes to charge your car’s battery depends on the size of the battery, the amount of current the car charger can handle, and the speed of the charger. The size and capacity of the battery block are expressed in kW. The larger the kW number, the larger the battery capacity and the longer it takes to replenish the capacity.

The charger provides power in kW, with power ranging from 3 kW to 150 kW, and the larger the number, the faster the charging speed. For example, a Nissan Leaf with a 40 kWh battery capacity will take about 12 hours to fully charge on a regular charge, but with the latest fast charger at the charging station, it can go from 0 to 80% capacity in a single charge. within 30 minutes. Or like VinFast VF e34, the manufacturer said, it can be quickly charged for 18 minutes to run 180 km.

Types of chargers

There are basically three types of chargers, including slow, fast and super fast. Slow and fast chargers are often used in homes or street charging stations, while super fast chargers are often found in dedicated charging stations, on long routes.

Some charging stations have a built-in cord, and you just need to plug the cord into the car charger socket. However, there are also many charging stations that require the use of your own charging cord, which you usually have in your car.

With slow chargers, this is usually a home use charger with a “hot-cold-ground” three-pin plug. Charge with a capacity of only 3 kW, so with a large vehicle battery capacity, it will take a long time to fully charge the battery.

Conventional fast chargers, which supply power from 7 kW to 22 kW, are popularly known as wall chargers. To install this charger at home, you need to contact your local electric power to survey the line, providing enough current to use this charger for your car at home.

The Super Charger, as the name implies, charges fast and the current is large. Typically, the power of superchargers is from 43 kW to 150 kW, in some cases, restoring 80% of the battery capacity within 20 minutes.
