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."

    Low range indicated at 100% charge

    I just noticed that I have an indicated range of only 285km with 100% battery, which is disturbing. Recent 1st year service at 7000 miles states battery is 100% on tick box. Since the service I’ve noticed my efficiency is in the low 2’s regardless of how I drive, but I have been using the heated...

    Charging losses

    I recently upgraded my MG5 from a 22 plate to a 24 plate FL. Now I have the app I have noticed that when charging with a 10 amp that should be pulling 2.3 kW at least, the app tells me it is charging at 1.6 kW. Surely there is not a 25% efficiency loss, or is there?

    Seeking Advice on ZS Hybrid Plus Fuel Efficiency and Electric Motor Usage

    Hi everyone, I recently bought a ZS Hybrid Plus and have been driving it carefully for 10 days now, with a daily commute of 20 miles, switching to eco mode and using the regenerative 3 setting. However, I’m concerned because I’ve yet to see any significant improvement in fuel efficiency...

    Efficiency

    I've had my MG4 Trophy long range now for around 3 months and while I'm delighted with it I have to say the miles per kWh I'm getting is disappointing. I had the MK2 LEAF before and while it's range was at best 150 miles on a full charge I averaged 4 miles per kWh. My MG4 is only managing around...

    Is my MG4 miles/kWh trying to gaslight me?

    I know the mi/kWh in winter should be worse. But since my last charge to about 80%, it estimated about 3.4 miÔ/kWh and I had covered about 50 miles and it was about 38%. I then charged to about 86%. Just didn’t sound right to me so I broke out the calculator. Ok so I charged with 29kWh and...

    MG ZS Long range Efficiency

    I'm very happy with our purchase of 2023 ZS EV Trophy long range... MG state a 440 km range but to my surprise even with 50% charge it was still showing 236 km range. Have seen as low as 14.4 kWh / 100km.. Only charged once to 100% and was displaying 463 km. Dec 2024: lately full charge 100%...

    6,000 miles range possible?!!!

    Something that puzzles me. Why would MG choose an axis scale that goes from -20 to +80 miles per kWh? 80 miles per kWh would give a range of 6,000 miles!!

    Keeping track of my MG4 (efficiency)

    Hello. I'll be using this thread to share information with you about my MG4, and at the same time I'll use it for myself, for keeping track of its mileage, etc. As a small introduction, I got my MG4, new from the dealership, at the beginning of June 2024. It is a MY23 MG4 Standard (with the...

    Better alternative to miles/kWh?

    Why not display miles travelled per battery % used (M/%U) rather than M/kWh? Then the remaining range displayed can be a calculation of M/%U x remaing_battery_% (M/%R) ? Much simpler and in my experience, accurate. Thoughts?

    How accurate are the "Current Journey" Stats or is my battery goosed

    I noticed this earlier in the year and been waiting on long drive to confirm, if those dash stats are correct then my battery has quite a lot less capacity than it should. The car is a 2023 ZS facelift, short range LFP battery. On a long run I'm only getting an actual battery capacity of about...

    Highest Efficiency Number You’ve Seen?

    What’s the highest efficiency number you’ve seen? For me it was 7.3 mls/kwh which was after a short 2.8 mile journey.

    Overdrive - why not?

    When I was a nippa many cars were fitted with an overdrive gear activated by a switch on the gear stick or a stalk. It gave you a higher cruising gear. Has anyone seen anything like this in an EV? With a reduction gearbox and buckets of torque available in every EV it would seem an efficient way...

    20mls/kwh

    I hope you are all enjoying the OTA update that unlocks 20mls/kWh mode. It's been very effective today, if you haven't got it yet run down to your dealer and get it installed: Ok, I jest, but did enjoy the 4.6 mile downhill run from Quernmore to Lancaster today. Still working on getting the...
