efficiency

Efficiency is the often measurable ability to avoid wasting materials, energy, efforts, money, and time while performing a task. In a more general sense, it is the ability to do things well, successfully, and without waste.In more mathematical or scientific terms, it signifies the level of performance that uses the least amount of inputs to achieve the highest amount of output. It often specifically comprises the capability of a specific application of effort to produce a specific outcome with a minimum amount or quantity of waste, expense, or unnecessary effort. Efficiency refers to very different inputs and outputs in different fields and industries. In 2019, the European Commission said: "Resource efficiency means using the Earth's limited resources in a sustainable manner while minimising impacts on the environment. It allows us to create more with less and to deliver greater value with less input."Writer Deborah Stone notes that efficiency is "not a goal in itself. It is not something we want for its own sake, but rather because it helps us attain more of the things we value."

    My first 300

    I appreciate others have done it, but I got there for the first time today in my ER. Set off from Chester at 100%, with a GOM of 327 miles. 76 miles to Ludlow in the morning and 327 more to Norwich later in the day. Arrived with 8% ‘in the tank’. My wife and I shared the driving and the boot and...

    MG3 Hybrid mpg claims, how reliable?

    The trip to the gym; The trip home; That is quite a difference. The trip home is slightly uphill, as well as being a minute quicker and 2mph more, but 27.4 mpg more is a lot. Overall, the car indicates 58.9 mpg and has done so for weeks now, no matter what driving we do.

    MG4 discharge curve

    Hi, i noticed that when i charge my 64kWh to 100%, the discharge is not normal. For example, at 100% a 20km trip can take 4%. And from 80% the same trip can take 7-8%. This is normal? Should I do an SOH test?

    Sweet spot for consumption…

    Finally found the sweet spot for consumption in my MG4…Sport mode with Adaptive Regen. Regardless of the type of roads driven - town, B roads, A roads and motorways that combo delivers by far the best returns for me. Easily getting over 4m/kwh in most situations (with the better weather of...

    5.5 miles/kWh!

    Having driven (MG5 FL) from west to South London (mainly south circular!) & back. That's 34miles (including 2 stops) and (yikes!) no queues. However, Sadiq controls the GL area (20mph limits) so the average speed was 13mph? As to miles per kWh the car indicated 5.5. Sounds good, but a little...

    MG4 LFP Battery state of health

    Hi everyone! I'm second owner. It had 10500 (6524 mile) kilometers on it when I bought it and SOH was 93.64% . Now my car is 17500(10873 mile) km and SOH is 93.15%. There is a difference -0.49% in 7000 kilometers. I just wanted to hear your ideas and suggestions. First of all is it normal...

Route is A1,A66,M6,M74. Harrogate because it is another option from using Gridserve at Wetherby (78p per...

    How many miles per kWh can you get?

    Now it’s a bit warmer I am getting much better range. MG ZS EV LR SE. Nov 2022. Didn’t have aircon turned on. Was doing mostly 20mph as it’s the Welsh speed limit. Can anyone beat this?

    Better mileage than range prediction

    I wonder if anybody else has experienced the same as me. I have a 70 reg mk1. I charged it to 100% and the range was 151 miles. I have since travelled 78 miles but the range has only dropped to 90 miles.

    My new MG3 Hybrid

    I took delivery of a new MG3 Hybrid Trophy in Battersea blue on Friday last week 3rd May. This is my daily runabout and replaced a 3dr DS3 which I had from new for just over six years. I have to say how impressed I am with the car, particularly from the value for money perspective. Compared to a...

    Record high MPG - can anyone beat this!

    HI, I'm a new PHEV owner. Did a mixed drive (town traffic/highway) on pure EV mode and the MPG just kept going up and up and up! Ended up on 562 MPG - it refused to go higher so maybe that's the upper limit on the counter. Either that or the car is faulty :) Has anyone ever hit these levels?

    SE LR not achieving range I'd expect. Anyone to compare with?

    SE LR not achieving range I'd expect. Charged my 2023 SE LR yesterday to 80% and drove 101 miles achieving an average speed of around 53mph due to spending over half of that time on the motorway. After 101 miles I was left with 20% battery. Can anyone tell me if this is roughly expected? The...

    Power consumption

    hi I have a standard MG4 , and I registered that my consumption is rocket high compare to test. In average 26 - 28 kWh/100 km Is this as expected ? Temperature around -5°C

    First long trip, wow

    Yesterday I did a 120 mile round trip for the first time and quite impressed. I managed a 4.1miles/kWh so was quite surprised as I only get 2.4 ish around town. I loved it, can't wait again

    About my Chinese Cyberster

    I decided to make my own topic so as not to clutter others. Continuation about working on the wind deflector. They made my first sample. I tried to check the efficiency at a temperature of 4 degrees and it’s difficult to understand, but there is certainly less wind in the cabin. I will order...

    What Car EV Range and Efficiency Test

    What car recently put this out. Some interesting conclusions: Tesla most efficient by some margin MG4 joint sixth most efficient, mid-table Many cars overestimate or underestimate their efficiency by a lot, MG4 and Tesla spot on accuracy, BYDs and others lie a lot. (could this be down to...

    Evse efficiency question

    My dno came today to try moling under my resin bound driveway to get my supply unlooped but they failed to get the mole to break out in the target trench. From what I can tell electricity northwest don't favour/allow dynamic load management as a long term permanent solution. I was going to ask...
