slow charging
Slow light is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. Slow light occurs when a propagating pulse is substantially slowed by the interaction with the medium in which the propagation takes place.
Group velocities below c were known to be possible as far back as 1880, but could not be realized in a useful manner until 1991, when Stephen Harris and collaborators demonstrated electromagnetically induced transparency in trapped strontium atoms.
Reduction of the speed of light by a factor of 165 was reported in 1995. In 1998, Danish physicist Lene Vestergaard Hau led a combined team from Harvard University and the Rowland Institute for Science which realized much lower group velocities of light. They succeeded in slowing a beam of light to about 17 meters per second. In 2004, researchers at UC Berkeley first demonstrated slow light in a semiconductor, with a group velocity 9.6 kilometers per second. Hau and her colleagues later succeeded in stopping light completely, and developed methods by which it can be stopped and later restarted.In 2005, IBM created a microchip that can slow down light, fashioned out of fairly standard materials, potentially paving the way toward commercial adoption.
Hi All,
Took delivery of a new MG ZS Trophy LR this week. Charging it for the first time tonight at home, and the car says it's charging at 16A and is predicting a charge finish time far longer than I'd expect. When I look at my in-home smart meter display, I can see the house is drawing 7.7kW...
Hi all,
I have a 2022 ZS Trophy LR, and a SyncEV chargepoint at home. I use Octopus Go, with the SyncEV taking care of the scheduling. That part works fine, with the car taking a charge between 0030-0430 as expected. What is concerning me is that the rate of charge has been lower than expected...
I noticed with my MG4 Long Range that when charging at a fast charger, the speed is not exceeding some 62 kW and that not even continuously. Outside temperature was some 2 C and the initial charge of the battery was 17 %.
Can anybody tell me if this disappointing speed is normal with an MG4?
Is...
Hi everyone,
I had the type 2 cable since I bought the car and it used to charge at 7.2-7.4 kW.
Over last month I noticed the charging speed has dropped to about 3kW.
I tried it at work and the Tesco Podpoit with similar results
I know it's not a problem with the car, because I can charge at...
We got our MG4 Trophy Long Range 3 days ago and charged it at a public charging station which is 22kW 3-phase.
I didn't realise that the cable supplied by MG is 32A single phase and not 3-phase so not able to get full 11kW of charge available. Ours was the only car connected to the 2 port...
Newbie here so basic info needed, but can't find it!
Just purchased 2021 MG5. Didnt come with granny cable so need to purchase one, but very confusing info online.
Think I need 3 pin to type 2 (?). Want to be able to slow charge as this is best for battery life (I think).
Also where is good...
