How to Use DC Fast Charging for Hybrid and EV? – AC charging is the simplest type of charging. AC charging outlets are everywhere. And nearly all the EV chargers you find in homes, shopping malls, and the workplace are AC Level 2 chargers. AC chargers provide power to vehicle chargers of course including hybrids and EVs. The AC charger will convert AC power into DC to supply power to the battery. The acceptance rate of built-in chargers varies by brand but is limited for reasons of cost, space, and weight. This means that the length of charging time depends on the type of vehicle. To do a full charge it takes us anywhere from four or five hours to over twelve hours at Level 2.
What is DC Charging?
DC Fast Charge is very different. DC Fast Charge bypasses all the limitations of onboard chargers and conversion requirements. Instead of delivering DC power directly to the battery, it is still possible to significantly increase the charging speed. Charging time depends on battery size and dispenser output. Although it still depends on other factors. However, the batteries in both hybrids and EVs are already capable of 80% charge in about an hour or less using most of the DC fast chargers available today. That is a fairly short time considering the development of electric cars is still in a matter of one or two decades.
Having DC fast charging is very important for hybrids and EVs. Especially for long-distance travel and large fleets. High mobility allows the driver to recharge during the day or on small breaks with a full load.
Unfortunately, older hybrids and EVs have a limitation that only allows them to charge at 50kW on a DC unit. That is if they can do it. However, newer vehicles are now out which can receive up to 270kW. As battery sizes have increased significantly since the first EVs hit the market, DC chargers have gained increasingly higher output for charging. Even some vehicles are capable of receiving up to 350kW of power.
Currently, in North America, there are three types of DC fast charging: CHAdeMO, Combined Charging System (CCS), and Tesla Supercharger.
All major DC charger manufacturers offer multi-standard units that offer the ability to charge via CCS or CHAdeMO from the same unit. The Tesla Supercharger can only service Tesla vehicles. However, Tesla vehicles can use other chargers, specifically CHAdeMO for DC fast charging, via adapters.
The basis of the Combined Charging System (CCS) is an open and universal standard for electric vehicles. CCS combines single-phase AC, three-phase AC, and DC high-speed charging in Europe and the US. All in one system that we are easy to use.
CCS includes connector and inlet combinations and all control functions. CCS also manages communication between electric vehicles and infrastructure. Thus, it provides a solution for all charging requirements.
The second DC charge is CHAdeMO. CHAdeMO is the DC charging standard for both hybrid and full EV electric vehicles. This type of charging allows seamless communication between the car and the charger. CHAdeMO Association developed this DC charging. Apart from developing these chargers, they are also in charge of certification, ensuring compatibility between cars and chargers.
This association is open to any organization working to realize electromobility. Japan is the place where this Association was founded. Currently, they have hundreds of members from all over the world. In Europe, CHAdeMO members based in a branch office in Paris, France, are actively reaching out and working with European members.
Who does not know this electric car company from the United States? Currently, Tesla already has a charging system for its output cars. A business model that is likely to cover all facets of Tesla’s cars.
Tesla has installed their own chargers across America (and possibly the world) to provide long-distance driving capabilities to Tesla vehicles. They also place chargers in urban areas. An area where available to drivers throughout their daily lives. Tesla currently has over 1,600 Supercharger stations just across North America.
How to Use DC Fast Charging for Hybrid and EV?
As we outlined above, DC fast chargers charge faster than Level 2 (AC) chargers. Like a Level 2 charging station, just tap on your phone or card, plug it in to charge, then continue your journey. The best time to use DC fast charging is when you need an immediate charge. The consequence is that you are willing to pay a little more.
Check Your Car and Connector Type
DC fast charging uses a different connector from the J1772 connector found on AC Level 2 chargers. Leading fast charging standards are SAE Combo (CCS1 in the US and CCS2 in Europe), CHAdeMO, and Tesla (and GB/T in China). More and more cars have DC fast charging systems these days. But be sure to take a quick look at your car’s ports before trying to plug it in. Here are some of the common connectors seen:
Save Fast Charging
Charges are typically higher for DC fast charging than for Level 2 charging. Given the added cost, fast charging doesn’t add up on a daily basis. But there’s another reason not to go overboard on DC: a lot of power flows from DC fast chargers and managing it puts extra strain on your battery.
Using a DC charger all the time can reduce the efficiency and life of your battery. So you should only use it when you really need it. Keep in mind that drivers who don’t have access to charging at home or at work may rely more on DC fast charging. Using fast chargers when you don’t really need them can prevent someone who desperately needs money from getting one.
Every car battery follows a so-called “charge curve” when it charges. Charging starts slowly when your car monitors several factors (from battery charge level to the weather outside), rises to top speed for as long as possible, and slows down again by about 80% to extend battery life.
With DC fast chargers, we recommend unplugging when your battery reaches about 80% charge. That’s when charging slows down dramatically. It can take almost as long to fill the last 20% charge as it takes to reach 80% at the start. Unplugging when you charge up to 80% is not only more efficient for you, but also considers other EV drivers.
