About this video:
Range anxiety is the fear that the electric vehicle does not have enough capacity to travel anywhere that is far away. This means no EV road trips, no leisurely drives through the mountains, potentially even no cross-city travel. Yes, EV range is continuing to grow, but it is nowhere near the range of its gas-powered equivalent and the charging times are still relatively longer.
Mitigating this issue is DC fast-charging. They can charge many electric cars to 80-percent capacity in around 30 minutes, though charging rate slows down significantly after that to avoid damaging the battery pack. The tradeoff is that DC fast-charging stations are more expensive to install and operate. Large scale adoption of electric cars is possible with higher charging powers and more fast-charging stations. This allows the car makers to use smaller battery packs, thus reducing the cost of an EV’s most expensive component. Hence, could be a possible solution for the range anxiety.
We know that fast charging is quite attractive in the sense of high power charging with short charging times. But how does a DC fast charger work? What are the different DC charging systems around the world? Gautham Ram Chandra Mouli will be answering these question for you in this lecture. Find out now!
Learning goals:
What are key parts of an DC charger?
What types of connectors are used for DC charging?
What are the limitations of DC fast charging?

Thank you for this session. I want to ask does CCS1 and CCS2 has the same communication protocol? If yes why we don’t have adapter from CCS2 to CCS1 and CCS1 to CCS2 ?
CCS1 and CCS2 use the same communication on control pilot CP. The two plugs are used in two geographically different regions (e.g., CCS1 in USA,Japan and CCS2 in many EU countries), so you will not normally find CCS1 and CCS2 plugs in the same region. Hence, there has been no major demand for adapters to convert between each other.
Gautham Ram the problem is in Egypt the country protocol is the European protocol CCS2 and the government allowed to import used EVS from any country and most of used cars we have here are American and CCS1 so we can’t charge by the available CCS2 chargers:
There’s a company called SETEC do this adapter but unfortunately this adapter only work with ABB not EVBox.
@@aymanmohamed1068 This is indeed a unique situation and i was not aware of this. In such a situation, an additional issue will be of AC voltage which is ~110V for CCS1 AC charging and about ~230V for CCS2 AC charging. You are referring to this adapter ? www.setec-power.com/index.php?m=content&c=index&a=show&catid=16&id=28
Gautham Ram yes exactly but regarding the AC we don’t have any problem just you need a cable from type 2 to type 1 and it will charge on Level 2 /220V.
The real problem in DC charging and the adapter.
I thought we can work on a solution like Tesla Chademo adapter.
I would like to get in touch with you as we work on this project now and can share with you a lot of field experience regarding this topic.
I added you on LinkedIn my name is Ayman Mohamed.
@@aymanmohamed1068 Sir I want to talk something related to this, so can I connect with you on LinkedIn? Also are you from zagazig University? Asking to confirm if the profile I found is yours
Very clear and concise.
after watching so many videos finally i was DC fast-charged in just no time... thank u so much, sir ...
Very Nice explanation sir. Keep posting such videos.
Nicely organized, good flow & Informative. Thank you!
Thank you very much, Dr. Chandra Mouli, for the information! Best charging explanation on the tubes!!!
Very clear and concise. Amazing video!
Thanks for this nice presentation👍you made fast charging mechanism of EVs very clear and structured.
We benefit from your tutorials in Jordan, Thank you sir 🙏
nice video, good summary and explanation
It is very informative. Thank you.
Great video! Thank you!
Love it sir thanks so much for sharing all knowledge and information in India for first time
Thanks
This is great! Thank you!
Perfect xplanation. Thankyou
Nice presentation. One doubt is since CCS1 and CCS2 is having both ac and dc charging, whether PLC is the communication over CP is the recommended method for ac charging also.
Great video!
Hello Gautham ,
Thanks for the videos on AC and DC charging .
Can you help me how LMS ( Load Management System) will take part in multiple connector .
Excellent.
very nice explanation!
Thank you for that informative detail. It looks like as EV is at its infancy car manufacturers around the world will need to adopt some controlled standards on these different plugs. Also learned that these Dc fast charges are eventually going to degrade the power source of the battery units and I can see that any replacement or correction is going to be at a big cost to the owners.
Thank you
Do you have any simulink model for dc fast charging station,if yes please make a tutorial video on it too
Thanks for this very nice Prasentaion.
Please Give one Prasentaion On large SMPS using In Ev Stations
Sir I’m looking for 12v 30amp Dc to Dc charger for my car to charge my in house battery. Can you suggest me where can I buy one in India. It would be a great help. If you could also kindly suggest about the voltage sensor relay or isolator brands in India. Thank you please. Request to give lecture on the topic above.
Hi, what is the charging stanard type used by Ola scooters?
Thank you very much
Hi mr ram
Thinks for explain
If i want to change the ccs1 socket in my car to ccs2 is there any problem because in my country the adapter not allowed in all stations
Question, if I have a charging system on board the vehicle, where do I tap in so I can charge while driving the car
Neat explanation.
thank you very much
Hi, how vehicle controller is waked up in charge connect. Charger is possible high voltage vehicle controller needs 12 v
Extreme Excellent 👍 Video Clip information 👌👍👌👍👌👍👌👍👌💗👍
So essentially the DC fast charging only goes to approximately 70-80% SOC using CC and that is where the charging ends with DC fast charging. The CV charging is not normally done by DC fast chargers and would have to be done using AC charging. Is that right?
Why is the fast charging upgrade so expensive when all the control electronics are off-board anyway?
very informative
Well Explained. I have a question. Is it possible to charge using external battery. What is the range of DC voltage in DC charger. In a total off-grid solar setup, is it possible to charge the car using a DC voltage stored in a battery. Yes I agree to the fact that I have a to develop a DC current controller to save the external battery from over discharged current. Does such architecture commercially available? I see converting AC to DC with a rectifier or inverter circuit would add to energy loss. Looking for an option to inject DC just next to the rectifier in commercial EV charge stations.
You may not get sufficient power with battery packs
Good video. But what a mess with so many different charging types.
Is the rectifier just an inverter?
what is the objective and outcome for Dc charging station for hybrid electric vehicle
hi Gautham do we need to take a license to open a DC fast charging station in India. Can we start our own DC fast charging station company and install few DC chargers in India without much beurcracy.
I am planning to by a Electric Bike, it natively support 1.2kW and 3.5kW charging with first party carryon charger, since bike has CCS connector, would I be able to charge it at these 4-wheeler charging stations? If so what would be fastest it can safely charge at?
Fyi: Battery is 10.4kWh
What are the manufacturers of fast chargers for cars
Sir i am keen to learn EV design from where i can get resources for that??
Great
Explain flash charger using supercapacitor
Спасибо Большое этому индусу
Sir can you share this ppt
nice.....
👌👌👌👌
sir, you are doing a very good job and this session is excellent can I get your email
bro . we look exactly the same. might not look like it in my picture. i showed this to my girlfriend she thought it was me presenting for a second. Anyway, i think we should meet up cos im interested in this field as well and we could discuss business
You need a good tie bro. Make u look slick AF.
Can i have your email please
Hindi dubbed karo
Hurrr bokachoda
There is no such thing as Level 3 Charger
Great video!
