All You Need to Know About Electric Car Battery Charger

What exactly is an electric car battery charger for?

An electric car charger is a device used to charge an electric vehicle's battery, sometimes called an EV charger. It gives off the required electrical power to refuel the car's battery pack. Electric car battery charger supplies electric power to replenish the batteries of electric automobiles. These chargers operate by converting AC power from the wall socket to DC electricity, which is then applied to the automobile's battery. The chargers are available in various styles and dimensions and may be used in private and public charging stations. Here are some essential details concerning battery chargers for electric cars:

Charging Levels of electric car battery charger:

Level 1, 2, and DC rapid charging are electric car chargers with various charging capacities. The rate at which the vehicle's battery is charged depends on the charging level.

  • Level 1 Charger: 

The standard charger that usually comes with an electric car is called a Level 1 charger. It charges slowly and plugs into a 120-volt AC socket in most homes. For overnight charging or when you have lots of time, level 1 charging is appropriate.

  • Level 2 Charger:

Like a major household appliance like a clothes dryer, Level 2 chargers run on 240 volts of AC electricity; they are often placed in homes, offices, and public charging stations and provide quicker charging than Level 1 chargers. Level 2 charging can be done every day or overnight.

  • Level 3 Charger (DC fast charging): 

DC fast chargers, sometimes called level 3 chargers, deliver high-voltage DC power straight to the vehicle's battery to enable quick charging. Compared to Level 1 or Level 2 chargers, they can charge an electric car far more quickly and are often available at public charging stations. When you need to fast, charge your car or for long-distance travel, level 3 charging is advantageous.

Connector Types of electric car battery charger:

Different electric cars link with the charger using various connection types. The most typical types of connectors are:

  • J1772:

The Level 1 and Level 2 charging connection standard in North America is J1772. It is a universal connection that most of the area's electric cars will accept. 

  • CCS (Combined Charging System): 

The J1772 connector for AC charging and an extra set of connectors for DC fast charging is combined into the CCS (Combined Charging System) fast-charging connector type. CCS is becoming more widespread in Europe and North America.

  • CHAdeMO: 

Japanese electric car manufacturers are the main users of this fast-charging connection type. It allows for DC quick charging.

  • Tesla Supercharger: 

Fast charging for both AC and DC is possible with Tesla automobiles' custom connection. Tesla owners may charge their cars quickly at Tesla Supercharger stations, exclusive to Tesla automobiles.

Types of electric car battery charging stations:

  • Home Charging Stations: 

Many electric car owners install a Level 2 charging station for easy charging at home. These charging stations allow quicker charging than a typical 120-volt outlet; however, they require expert installation by a licensed electrician. Smart charging capabilities, scheduling choices, and connection options for monitoring and management are frequently found in home charging stations.

  • Public Charging Stations: 

These stations can be found in various places, including parking lots, malls, and highways. They let owners of electric vehicles charge their vehicles while they are on the road by providing Level 2 charging and Level 3 DC rapid charging. While some public charging stations demand a fee or membership, others could provide free charging.

What are the benefits of a 22KW Electric Car Charger for a Home, Level 2 Charger?

  • Quicker Charging: 

Compared to a Level 1 charger, a 22KW Level 2 charger enables much quicker charging. This electric car battery charger can produce up to 22 kilowatts of electricity, although Level 1 charging normally uses 1.4–1.9 kilowatts. As a result, you may charge your electric car considerably more quickly, cutting down on the total charging time.

  • Convenient Overnight Charging: 

You may charge your electric vehicle (EV) overnight at home with a 22KW charger. You may be sure that your vehicle's battery is completely charged by the time you need to use it the following day because it enables quicker charging. As a result, there is no longer a need to rely entirely on slower Level 1 charging or public charging stations.

Level 2 chargers cost more initially than Level 1 chargers, but they are less expensive over time. You can benefit from off-peak power costs, normally lower if charging speeds are higher. Over time, billing at off-peak times can considerably lower your expenditures.

  • Energy Management and Smart Features:

Numerous 22KW chargers are equipped with energy management and smart functions. You can plan charging sessions with these capabilities, keep an eye on your energy usage, and even combine them with smart home technology. You can optimize your charging habits with the help of energy management features, guaranteeing effective energy use and lowering total electricity bills.

  • Increased Daily Range: 

With a 22KW charger, you can charge more quickly, increasing your daily mileage. A Level 2 charger helps you to recharge your car more quickly if you routinely drive long distances or have a longer commute, maximizing your daily range and easing any range anxiety.

  • Flexibility for numerous EVs: 

If you now own numerous electric vehicles or want to do so in the future, a 22KW charger gives you options. Multiple vehicles may be charged concurrently, ensuring they are all prepared for deployment when required. This is especially advantageous for families with several drivers or companies with an electric car fleet.

  • Reduced Dependence on Public Charging:

Your dependency on public charging stations is decreased when you have a 22KW charger at home. Even while the infrastructure for public charging is growing, certain places could still be more convenient and more comfortable. In particular, during peak charging times or when public charging stations are crowded, having a Level 2 charger at home gives you a dependable and practical charging alternative.

  • Environmental Benefits: 

Using a Level 2 charger to charge your electric car at home help to reduce greenhouse gas emissions. Driving an electric car has several environmental advantages, which are further enhanced when charging during off-peak hours when you may benefit from cleaner, renewable energy sources.


The electric car battery charger is a necessary part of owning an electric vehicle; therefore, picking the best one for your vehicle is crucial. The kind of battery, the current and voltage requirements, and safety features are all things to consider. With OCPP protocol docking and international platform deployment capacity, PIWIN has been actively involved in the R&D and manufacturing of AC and DC chargers for new energy vehicles in abroad markets for a long time. The EV charger technology used by our organization is exceptional and has a wealth of knowledge.

Efficiency: DC charging stations are increasingly integrated with renewable energy sources, such as solar and wind, enhancing the sustainability of EV charging.
