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."

    Moving energy companies.

    I charged my car on Sunday to a full charge from 5 miles left on battery, this is the total electric used which includes all my domestic appliances for the full day, I'm quite happy with this and I don't feel the need to go searching arround for a cheaper tariff.

    A week away without charging report

    I thought I'd post about my latest trip away without charging, to give you an idea of the MPG I got. Trip is about 130ish miles away, mostly motorway with a couple of miles before the M5, and then about 20 miles of hilly devonshire countryside. This trip, I went on EV to the M5, then when I...

    How is Range Calculated?

    Obviously it uses your driving efficiency but when from? Is it possible to start a new trip and reset the estimate if the driving efficiency will be a lot different e.g. motorway instead of city, or using a trailer?

    HVAC Power Use

    Apologies if there is an obvious answer for this: I have a PFL MG5 with the "two dials" HVAC controls, rather than climate control. What does the white, middle section of the temperature setting mean? Does it mean "not heated, not cooled", or does it mean "medium temperature"? I like to use...

    Amazing battery efficiency on my 3 year old ZS LR

    A journey to Woking from Kent and return Thu 22nd - Sat 24th, 167 miles on M20-M26-M25-A3 and local roads with ambient temp 16C-18C, two adults with luggage. But 4.4 miles per kwh? Really? This is Tesla territory. Battery was 100% charged before departure on 7Kw home charger, topped up on a...

    Driving range

    Apologies if this has already been discussed, but there are are so many threads it is hard to find what I am looking for. I have a new MG ZS EV It is claimed to have a range of 440 km, but I'll be lucky to get 320 out of a full charge. Is this normal? Allan. MELBOURNE

    Consumption on short trips

    Hi, I'm considering buying a ZS hybrid+. What is your fuel consumption on short trips? Around 4-5km. I heard somewhere that the petrol engine switches off after about 15km of driving, so that's when the consumption is said to be 5l. By then it's said to be around 8l. Is it true? How are you...

    Speed and time saved

    Quite an amusing video describing how little difference going really fast (70+) compared to say 60 makes when travelling. Possibly quite relevant to an EV which gets decidedly less efficient at higher speeds. Play at full size if possible for better viewing

    Range ok on this car?

    Hi all. On verge of buying an MV5 61.1kWh. 38000 miles. 2022 21 plate. Battery charged to 100%, car says range 195 miles. Is that bad? Thanks for any input. Ian

    Air Con vs Heating etc

    Hi, In ICE cars we all know that AC on means compressor on and loss of power/poorer fuel consumption. I've never noticed having the fan on gently made much difference to the MPG either. Now when I turn the fans on, even at pretty much ambient temperature and leave it on low, the mileage drop...

    Thinking of a tow bar

    I’m considering adding a tow bar to my MG4 77kwh, mainly to tow the occasional small trailer for carrying timber and other items that might not fit in the boot. I doubt I would be towing for extended trips. I’m aware the car has a towing capacity of just 500kg. Has anyone got any advice on the...

    Best miles per kilowatt hour figure

    Hi everyone, I’d be interested to know what your best mi/kWh return has been on you MG EV4 Trophy and what type of journey was it ? Currently the best for me was 5 mi/kWh on a 10 mile commute to work temp @ 10 degrees?

    MG5 2023 Trophy Winter Mileage

    I am wondering if the driving range when charging at home to 100% and the outside temperature is around -1 via 3 pin 13amp should be more than 145 miles. I have found the last 2 times I charged overnight the range was 140 and 145 miles. Many thanks.

    Interpreting the consumption pie chart

    I went for a drive today. More on that separately - all good. 😁 The attached shows my consumption pie chart. Looks pretty clear - 60kWh driving, 3kWh AC, 63kWh consumed. 370km. It also says Regen benefit 23kWh, which I thought was impressive. Some very big downhills, that turned into uphills...

    Efficiency Reading Accuracy on ZS EV

    I was suspicious of the accuracy of the Power consumption figure given on the Information centre in my 2023 ZS EV Trophy LR display, so I decided to check it. At the start of the test, I reset the accumulated totals on the Information centre and charged the car to 80%. For about the next month...
