There are different standards that electric vehicle uses. Globally, several EV charging standards such as Type 2 Connectors, CCS, CHAdeMO, and GB/T are getting adopted.
The differences between them are :-
Level 1 chargers use a 120 V AC plug and can be connected with a standard electric outlet. They do not require installation of any additional equipment and easy to use.
Level 2 chargers are compatible with residential & commercial charging space. They use a 240 V (for residential) or 208 V (for commercial) plug and requires installation by professional electricians. They can also be installed as part of a solar panel system
DC Fast Chargers (also known as Level 3) They can only be used for commercial and industrial applications as they require specialized, high-powered equipment to install and maintain. IN DC Fast chargers, the electricity flows only one direction, so it’s exactly how the battery wants it.
Electric vehicles have different types of chargers for multiple types of electric vehicles. There are three main types of EV charging – regular AC chargers, fast-chargers, and rapid chargers.
Type 1 AC Charger
The simplest EV charger is commonly used by some entry-level electric vehicles. It requires an AC socket or home-charging system, and charging is slow. It provides AC charging power levels up to 220 volts and a maximum of 16 amps of current. While using it, the vehicle has to convert AC power to DC, which makes it a slow process.
Type 2 Charger
The Type 2 Charger provides faster chargers and is compatible with both AC and DC charging systems. These types of chargers work with three-phase input power systems. The Input power can manage between 7.4 kW to 43 kW with a 400-volt AC supply. Such types of chargers are usually installed for home as charging time is faster and also as it is compatible with vehicles with CCS plugs.
CCS or Combined Charging System
A combined charging system plug or CCS type plug (often called a CCS Type 2) is common in current age electric vehicles. These chargers can provide regular charging from home-charging stations as well as DC fast-charging for cars from commercial charging stations.
With global acceptance and presence in over 70 countries worldwide, this is one of the first types of fast-charging systems developed. It can handle DC fast-charging of up to 50 kW. But the new electric vehicles are now switching to CCS due to the versatility it offers.
The Indian government had recommended the GB/T type charger for EVs under its Bharat DC 001 standard. These chargers, installed by Energy Efficiency Services Limited (EESL), a government body, are capable of DC fast-charging with an output of 10-15 kW for low-power EVs.
Before making the selection, one has to determine if the EV owner wishes for a Level 1 or a Level 2 charger. Level 2 chargers are fast in charging as compare to Level 1 chargers and require a different power outlet that installation by a professional electrician.
Another factor that should be taken into consideration is the location of the EV charger. In case it is being installed in an open space and not inside the garage, make sure that it is durable when exposed to sun, wind, and water.
EV chargers are of 2 types:-
AC Chargers – AC charging is the simple way of charging the electric vehicle and can be easily installed at home, shopping plazas, and workplaces. An AC charger provides power to the on-board charger of the vehicle, converting that AC power to DC in order to enter the battery. These chargers are space-efficient, thus take longer to charge the vehicle.
DC Chargers – DC Fast Charging provides direct DC power to the battery, thus bypasses all of the limitations of the on-board chargers, thus takes less time to charge the electric vehicle. The time required to charge the vehicle depends upon on the battery size and the output of the dispenser, and other factors.
