EV Basics: Guide to Charging, Connectors, Efficiency 

Considering English not his first language he is extremely articulate and communicates a complicated new subject really well. Excellent video.

Very well structured and so insightful. With Evs becoming more popular the need for this information is higher. Now I know what Im reading and what to look for when comparing cars!!!

Brilliant brilliant brilliant video, I’ve been looking for something like this for a while in my researching the switch to EV. There are guides etc online but to have it visualised and analogised the way you have done it was so helpful, I’ll be referring back to this video time and time again I’m sure. Thank you!

best intro video I've seen to the concepts and varieties. thank you!

Excellent video for a newcomer into EV industry. Thanks buddy!

Just had my first ev for 2 weeks, love it - still got lots to learn. Great vid. Many thanks.

Very well presented and explained video Martin, thank you for taking the time to share your experience with us.

Thank you for the detailed and clear explanation on EV battery, much appreciated!

Another very informative and professional video. Thanks Martin.

Such a simple and wonderful explanation. Thank you!

Thank you so much for organizing the pieces of knowledge I had in mind to a full picture. Well done

Thank you! Excellent information for the video and very professionally delivered.

Great video! Very well explained, thank you!

I love the BMW i3 print behind you! Great information. Thanks

Very nicely explained. Thank you!

Very good explanation and graphics, thanks man!!

Excellent presentation!

Brilliant explanation

Good presentation. Thx . Very informative

Great video, thank you!

Very Brilliant and Excellent Information .

Thank you for this knowledge. I will buy my first EV, soon!

Best video ever on EV .

Very good thank you

Thanks really good video!

Great job !! Good information

Great video! Almost explains electricity better than university physics.

Excellent video. Will the content of is presentation will be same if we are charging a super capacitor instead of a battery? Appreciate your thoughts. Thanks

Great video. Minor point, volts is the unit of potential difference, not voltage.

Small correction about the connectors that Tesla use. Over in the US, Teslas use a proprietary connector. This is because when they were tooling up, the Type 1 connector was still in development. So they had to go their own direction. The Tesla connector is smaller than the Type 1 and this informed the design of the charging socket fascia. Fortunately, the Type 2 socket fits in the fascia of the Model S and X, but not the whole CCS2 socket. Tesla also favoured re-using existing pins in the socket for DC charging. Their own connector does this and that's why the Type 2 socket in the Model S does too. Tesla were expecting DC charging on Type 2 (CCS2) to take this solution. But the standards makers went for extra pins instead. So for the Model 3 they re-designed the fascia to support the full CCS2 socket.

Hi thank you, this helps me understand the fact the electricorik has 3 different measurements for the same thing that comes out the end of the cable…😮 What I am searching for is an explanation of what is in the “box” that is on a 240volt mode 2 , type 2 cable, how does that effect or modify the electric if it’s still the same in and out ..? Please 🤔

What adapter etc. would I need to be able to charge my mobility scooter cabin car from an EV Charger, here in the u.k. I currently charge it on a normal 3 pin plug like you would use for any electrical home device, kettle, fridge, microwave etc.

Hi I bought a simple Type 2 Mennekes plug to Scucko socket for my electric motorcycle which only has a computer power cable socket so 1kW AC needed. When the AC Type 2 stations has socket it fits in and works fine, but there are Type 2 EV charge stations with Type 2 cable instead of socket. In the cable end my Type 2 plug does not touch the pins, the plastic spacing is too long. Can I cot a centimeter from the plastic plug end just to fit both socket and cable Type 2 chargers?

Besides the video itself I live the light blue paint job on the i3 at 11:17. Have you thought about adding some orange accents? ;-) Honestly: Please tell me what that color is - I want that for my boring black i3.

Very helpful and informative- I have a Renault E tech - can I plug into Tesla stations with my type 2/ CCS cable?

What % of energy from your metered charger (or house meter) actually resides in a charged battery, usuable to the vehicle?

Can I charge intermediate charging with 7.2kW charger. Means 3 hours in the night 7pm-10pm then switch off and again initiate the charging 6am-9am. Will this be ohk or create any problem on LFP battery

sir how could i find a load for 9 meter bus of attery 350 kwh

I'm working on my mini project wireless EV charging...can you please help me

very informative and concise video, I m about to buy an EV from china which has a GB/T connector for DC charging however the charging stations at my country using the european standard (CCS) and I found adopters some people use to connect chinese evs to CCS chargers but some are saying its not safe I want to know your opinion if it safe or not, Thank you

Very good explanation but I still dont understand CCS. Why is it combined AC and DC in the same plug? Are there DC chargers which also outputs AC? Are there EV cars that can only be charge with AC and not DC?

Hi sir, if the i3s Rex I am looking for to buy comes only with type 2 connection, could it be charged at 43kw in a public charger or will not accept that speed? If yes, and it has a 40kwh battery capacity, could it be charged from 10% to 80% in around 35 mins? Many thanks in advance.

I bought recently a 2017 94h I3. It has arround 45.000 km. I did last week a 1200 km journey and used rapid charging. All of the stations, except one, were 50 kwh stations. No problems there. Arround 20/25 minutes to charge from 20 to 80%. The other station was a 160 kwh fast charging and when i plugged the car it started charging normally but when it reached 75% an error occurred. The charging was stopped and on the my bmw app two error messages appeared: impossible to fast charge and also the impossible to charge message. Later i plugged on a type2 charger and all the errors disappeared. So, on 50 kwh stations no problems. The only time i used a really fast station i had a problem. Any ideas of what could have happened? Greetings from Portugal. Nice video.

Is it true that charging any electric car to maximum capacity will degrade the lithium ions quicker?

Does the BMW i3 have pre conditioning for the battery?

hello, what is better for the batteries? charge 1 phase 7.2kw 32 amp or 3 phase 11 kw 16 amp? Thanks

I love my BMW i3. Still looking for a type 1 dc charger but that will come.

What would be the price to install a ccs connection in the i3? Thanks

What is thé best way too charge a BMW i3 94 h. Each day or once a week. I drive 30 km a day.

8:00 By original design, type 2 was AC 1 phase, AC 3 phase and DC. DC worked by combining AC L1 and L2 into DC-, and L3 and N into DC+. Each pin can do up to 80A AC (3 phase, or 50kW), and 100A DC, so it would be 200A at 400V, or 80kW. Renault Zoe in 2014 could charge up to 63A AC or 43kW, and by internal circuit diagram, up to 40kW DC, which was never enabled. Tesla uses longer pins, so it can push up to 150kW DC. So, Europe would never need NACS equivalent, type 2 was a good design from the start. Issue was that VW 'invented'. They limited their cars to single phase only, often 3kW. This way, their cars would charge for 20 hours. Then marketed CCS as improvement, to enable fast charging and paid options. In my opinion, EU should have never allowed CCS to become a standard, but VW has taken the money from the German government to build a CCS network, then it spread across the EU. And politicians are not electrical engineers...

How to increase the charging efficiency for ev

I would have equated volts to pressure and not pipe diameter... otherwise nice work

Isn’t it v^2 x I not V x I

If this guy thinks this is simply he's not living in the same world as the rest what a joke

50.000 euro for the electric VW Golf where I live. NO THANKS.
