Fact Check - All About DC Chargers
As a result of new technologies all around us, our lives have become more comfortable, more convenient, and even better. Do you remember how you used to wait by the phone for an important call? You've got your phone with you now. Similarly, this is the time for car innovation. The use of electric vehicles has already revolutionised transportation. You'll need to know about the many sorts of electric vehicle charging stations, and right now, you'll discover everything you need to know about DC chargers below.
Current scenario
With the rise of EVs, the fuel stations model should become an antique of a long-ago era, but you would not know it from the media emphasis on DC fast charging. Many customers insist that a DC charger would be more comfortable for charging on a long journey. Developing a better infrastructure means installing a DC charger at the charge stations. Fast charging has its space in the EV charging fauna.
What is a DC charger?
DC refers to ‘direct current’, the type of power that the batteries consume. In EVs, they have “onboard chargers” inside the vehicle that convert AC power to DC for the battery. DC fast chargers convert AC power to DC at the charging station. And bring DC power to the battery directly. Hence, they charge at faster rates.
Significant and instant charge facilities would be more attractive and lead to higher adoption rates.
Well, the DC charger is the future of all the upcoming EV’s. Also, salient feature for the cab companies and
corporates who might have a bunch of electric cars.
Let us know more about DC Chargers in detail.
Technical Specifications
1. As per the DC charging specifications, the power rates at 10Kw/ 15Kw/30Kw /50kW or even higher capacity.
2. The voltage carried out to be 48V/ 72V for Indian electric cars such as Mahindra e20 Plus P8, Mahindra e-verito, and also upcoming Tata e-cars.
3. Around 750V or even higher are used by global electric automobiles such as Nissan Leaf and others.
Types of DC Chargers
Level 1 DC Chargers
Level 1 DC chargers are those chargers whose output voltage is 48V/ 72V, with power outputs of 10kW/ 15kW with a current of a maximum of 200A.
Level 2 DC Chargers
Level 2 DC Chargers are those chargers whose output voltage is around 1000V, with power outputs of 30kW/ 150kW.
EV drivers frequently use these Level 2 chargers, which save almost 60% of fuel, compared to an ICE engine.
DC Plug Connectors
Further categorized into four types:
1. CHAdeMO - used by Nissan and other Japanese companies like Mitsubishi.
2. SAE Combo Charging System (CCS) by BMW, GM, VW, and others.
3. GB/T – BYD used by the other Chinese companies.
Indian electric cars and buses use the GB/T port on automobiles for DC fast charging. Also, the costs seem to be a vital factor in India for opting for GB/T compared to CHAdeMo or CSS. The charging duration depends on the size of the battery. And the output of the dispenser, and many other factors. But, many upcoming EVs are equipped with DC Chargers as they charge up quickly.

Top 5 Facts about DC Charger
1. Fast charging: DC electricity charges any electrical household objects faster than the AC power supply. Hence, DC is constant, the charging duration is not concerned by the output power of the charging point.
2. Expensive: DC requires a lot of power from the grid and, the tariff for it is also high. Charging stations offering DC ports require the biggest DC stations that need cooling commodities, which results in an increased installation, cost of production, and operation.
3. Upcoming Devices works on DC: the newly coming devices like mobile phones, new shavers, etc do not require a motor but can have a battery that runs on DC.
4. Supremacy of 80%: Most of the EVs, gets charged up at a faster rate until it acquires 80% charge of the charge. After that, the charging slows down. The 80% charge increases the life span of the battery.
5. Usage as per your convenience: the advantages are associated with the health of the EVs along with their batteries. But, in the case of the electrical stream, it does not contain a circuit breaker like AC does. In such a case, the external circuit fails to facilitate, and also your battery may get fried.
Renewable Energy
Most of the charging stations are connected to the grid, which relies on fossil-fuel power stations. Though, renewable energies can be used to reduce the use of grid energy. Nidec Industrial Solutions has a system that can be powdered using the grid or renewable energy sources like PV. The most interesting fact that SolarCity marked in 2009 was using of solar energy systems for charging installations. Thus, the company reveals a single demonstration station in partnership with Rabobank on Highway 101 between Los Angeles and San Franciso. This E-Move charging station is furnished with eight monocrystalline solar panels, which supplies about 1.76kW of solar power.
When it comes to India, we have many renewable energy sources such as solar energy, wind energy, hydroelectric energy, etc. With the help of these renewable energy sources, we can cut off the cost of the electricity used for EVs.
Final Words on DC Charger
DC fast charging is a crucial aspect in the view of high mileage/long-distance travelling. The immediate recharging option enables many customers for adopting EVs. An interval of 50mins for an 80% charge would be pretty good after a 400-450kms journey.
