dc charging

    How does CCS generate high voltages up to 920V?

    Hello, I am studying the design of DC fast chargers. I learned some information about their varieties and the approximate principle of operation (Vienna Rect. - LLC DC/DC - Output). Usually, after Vienna Rectifier, you can get a maximum voltage of about 840VDC, and then lower it to the...

    How hot should the batteries get while charging?

    I had always assumed that the battery pack required some heating before high-speed DC charging, but that once the charging got underway most of the noise the car makes was due to cooling. I had also assumed that ~25°C was best for the batteries. See this (admittedly old) post which mentions...

    Did you know the 3 heats the battery (actively) constantly while DC charging at any speed or temp?

    I bet you didn't. I'll bet you're thinking right now, "no, that's nonsense, that can't be right, let me get in this thread and tell this idiot off". Or maybe "what makes you think that, where'd you get that data?". Perhaps "no, that's just because DC charging causes the battery to heat up"...

    Supercharger - Brooklyn, NY - Brooklyn Museum

    This is so exciting. I just stumbled unto a completed supercharger at the Brooklyn Museum/Brooklyn Botanic Garden parking. Ten completed urban chargers. They are fenced, however, maybe for cosmetic work. My phone memory was full and I couldn't take any pictures. I will be going back to for...

With the ability to charge at 400KW, using technology already found in Tesla Superchargers. The CEO of the company has also said that he would install a Tesla plug if Tesla worked with...

    ICE Manufacturers not worried about the SuperCharger competition?

    At the risk of sounding like a click-baity thread, I didn't know what to title it, but I wanted to keep it broad. Apologies if this thread has been discussed elsewhere as I'm fairly new to the forums but have been trying to keep up around here. Some ICE dealers already have limited charging...

    Tesla Roadster: CHAdeMO 50kW DC fast charging!

    Elon zag het niet zitten om de Roadster eigenaars te voorzien van Supercharging, maar gelukkig was er nog QuickChargePower die hun CHAdeMO lader hebben aangepast voor de Roadster. Gisteren was het dan zo ver: de eerste succesvolle test! Laden ging vlot aan 400V+ 125A = 50kW. Dit moet toelaten...
