Combined Charging System (CCS) explained

[@mikeselectricstuff]

Your description of AC is wrong - In AC mode, the car does not tell the EVSE how much current it needs. The EVSE advertises the maximum available current to the car, and the car draws whatever it wants up to that maximum. This limit can vary during charging, e.g. for solar or load-balancing.

I suspect you often find people quickly remembering important appointments whenever they see you walk into the room.

Can we charge a vehicle using AC type-2 connector with DC current

[@muhammadan-nasdzikrullahbi9769]

Thank you very much for the explanation , i really appreciate it , i hope you can answer my questions above 🙏

[@mikeselectricstuff]

DC charging does not use the PWM signal. It uses the Homeplug Greenphy power-line comms protocol over the CP line when the PWM duty is

[@tedonash2681]

Yes as I said in the video I covered only basics and if someone needs to go deeper he/she can read the document linked in the video description. It is stated there on chapter 4 that CCS used Homeplug Greenphy power-line communication.

Hi sir , what do you mean by it does not use pwm signal ? Do you mean in order to control the amount of current feed into the car for dc charging , It does not use pwm signal just like how ac charging does ? Because i believe for ac charging the charger will send pwm signals to the car and exchange the max amount of available current with the car and the car will receive the current up to the max limit right ? But for dc charging , is the mechanism not like that ? If the answer no , then how can we prevent from overload / tripping occurs ? Because I believe for dc charging , the car is requesting the amount of current from the charger right up to the limit , but who determines the limit if pwm signal is not use ? Thank you very much , i hope someone can answer my questions , I really have doubt on this issues

It was great video! Can you please share the slides or PDF of those documents you showed in video?

[@sirigireddylakshmiprasanna7080]

Could you kindly make a video about SLAC, please?

[@jamesgarapati2500]

Good explanation thank you 🙏

[@mayurdugar03]

Nicely explained.

[@tedonash2681]

Thank you!

[@mladensantic]

Great video.

[@elmalek2007]

I’m at Egypt and here they use CCS2 for DC stations and I got Ford Focus Electric 2017 from USA and it’s CCS1 , I use adapter , I can charge fine with ABB stations , but I can’t using EVbox stations. The car starts the lock on the gun and then it unlocks and the charging session terminate , why is that. ???

[@tedonash2681]

Is there any error on the wall box?

[@elmalek2007]

No it just says charging session completed , after few seconds

[@tedonash2681]

Sorry Tamer I have no clue what may be the problem.

[@bryanne274]

Thanks Tedo!

How does the CCS chargers get the SOC on the car before charging? - I am quite sure I have see the SOC when charging my Tesla (Is it doing some canbus stuff somehow)

[@tedonash2681]

If you check the CSS documentation (tesla.o.auroraobjects.eu/Design_Guide_Combined_Charging_System_V3_1_1.pdf) on page 41 it is described: The High Level Communication in DC charging takes place via power line communication (PLC) and is used for exchange of charging parameters e g voltage and current as well as information's like state of charge, remaining charging time, next maintenance. There is also the possibility to enable and operate a payment system via high level communication.

@@tedonash2681 Great, and thanks for the reply :)

[@manikumarvasa4374]

Can we charge a vehicle-AC type-2 connector with DC current

[@udai4k]

One basic question - does DC DC charging and AC charging happen simultaneously at a time or one should opt of DC ultra fast charge or AC charge?

[@tedonash2681]

Very good question. Unfortunately I don't have an answer and also it is not defined in the spec. I think it should happen simultaneously but I haven't seen any DC fast charger having AC connectors in the DC plug

[@udai4k]

@@tedonash2681 I did ask some.of the experts, they are also of the similar opinion that if it's a fast charge station, then it's only either DC DC or type 2 AC

[@RajuPatel-zs2im]

@@udai4k On charging station EVSE there is display in which option are there to select AC or DC charging check ABB charger.

[@enginerepairguy]

can i then buy a car in the US and charge in europe by just using an adapter?

[@mohamedshafwan6070]

7:07 car is not sending PWM to charging station its other way. station sends 1khz PWM to EV

[@acntforyt9803]

So technically if I have Electric motorcycle which has CCS charging port, and company given charger of 3.5kW, I can still charge the bike at public car chargers which are CCS no matter if they are 30kW or 60kW, CCS standard will negotiate correct amperage for my bike and it will be safe?

[@tedonash2681]

Technically YES

[@madhub2654]

What will happen if set the PWM to 100%?.

[@ziggyyo]

No charging
