charging efficiency

In electrochemistry, Faraday efficiency (also called faradaic efficiency, faradaic yield, coulombic efficiency, or current efficiency) describes the efficiency with which charge (electrons) is transferred in a system facilitating an electrochemical reaction. The word "Faraday" in this term has two interrelated aspects: first, the historic unit for charge is the faraday (F), but has since been replaced by the coulomb (C); and secondly, the related Faraday's constant (F) correlates charge with moles of matter and electrons (amount of substance). This phenomenon was originally understood through Michael Faraday's work and expressed in his laws of electrolysis.

    Charging efficiency

    When we bought our MG4 two years ago I calculated its charging efficiency to be about 83%. I've now done the same calculations with our MGS5 and I reckon the charging efficiency is about 89% :) That's quite an improvement if you think about the cost of charging over a long period of time. (The...

    Mathematical charging anomaly ?

    Charged the car to 80% and ran it down to 30 % , did 174 km with the usage monitor hovering around 16.6 kWh/100km. All pretty much normal. Charged last night expecting to put in around 30kWh .... this morning the value was 21 kWh input, with the car again at 80% .???? The timer said 2hrs 15...

    charging rate difference

    mg zs ev trophy long range charging with ohme pro, whenever I charge, ohme shows charging at 7.18kwh but car only charging at 6.4kwh as per ismart app, where the rest of energy going, being charged for 7.18 by octopus ? Thanks

    Charge calculations NMC

    Hi all, I'm just trying to understand my most recent charge today. I charged from 25% to 80%, so 55% added. According to MyEnergi app, this was 33.53kw used at the wall which is roughly 55% as expected with a stated SOH at 96% at my last service in December 25 or 61.44kw. However as far as I...

    AC charging loss

    I have been charging in the cold these days. Efficiency goes down in the charging process as it gets colder, and is poor this time of year, with all the way down to 35% loss when it is really cold. For ok winter charging temps the loss on my IM6 is about 25%. So I tried a test with charging my...

    Battery Preconditioning

    Apologies, I previously raised this subject, however, it appears that there was confusion regarding ‘Battery Preconditioning’, and using the iSmart app’s facility to pre-heat the cabin/seats etc. To reiterate, my question relates to understanding exactly what PRE CONDITIONING THE (traction)...

    poor charging efficiency

    charged our ZS (standard range) last night - according to the charger we used 28.7kWh over the 4 hours we have cheap electricity. On the car battery this translated to +36% which by my calculation is 18.4kWh. So only 64% of the power went into the battery, this seems really poor as I would...

    HS PHEV battery charging

    Hi, forum, Just have fully charged my HS PHEV from empty. I used Pod point 3S wall changer, the app indicated it took 27 kWh. I wonder if anyone noticed over 24 kWh consumption when fully charging your car from empty. Also, on paper it is said HS PHEV battery capacity is 24.7 kWh, taking...

    Battery Preconditioning

    Now that temperatures are starting to drop in the UK, any advice from Cyberster owners who have driven in cold weather? At what temperature would preconditioning the battery be recommended and how long does it take to precondition?
