    Battery life and replacement cost

    Why would anyone pay that when you can get one for £5,000 used, the manufacturing cost is under $7,000. I smell dealership mark up. I’ll see if I can get into the manufacturing parts lists to check factory pricing for dealerships, I’m not in the car industry anymore but have been researching...

    Battery life and replacement cost

    Really, that sounds odd as surely the car as a whole is used to determine future values and depreciation, after all you wouldn’t separate the motor and charger. As someone who builds batteries from salvaged ev packs I’d ignore any reference to new replacement packs as you can get a complete low...

    Not getting the advertised range on full charge

    The indicated range after charging is based on how the car was last driven, speed, weather, acceleration, heat and aircon, auxiliaries etc. It will adjust as you drive so if you drive at a slower speed, weather is warmer etc it will decrease less in real time or drive faster in colder weather it...

    Gains from regen braking

    Set to full strength regen and using the throttle to regulate the strength from coast to full gives far more control. I’ve been driving and riding electric for over 10 years and build my own stuff too including battery packs. Converted my sailboat to electric drive with hydro-regen over the prop...

    Gains from regen braking

    Regen isn’t just to slow down to a stop, best method for efficiency is to feather the throttle to maintain a speed on a downward slope or reduce speed slightly to use a little regen. Long downhills though it’s better to coast, you can coast by adjusting the throttle to keep the power meter at 0...

    Battery life and replacement cost

    That doesn’t indicated a loss of capacity as it’s well within the nominal capacity from manufacture. If you 0-100% capacity test it you will find it is actually over what the manufactures state. My 64kwh usable capacity is 61.8 but on testing (minus some losses) it comes in at 62.6kwh. A few...

    Battery life and replacement cost

    4000 full (0-100%) charge cycles is about right for a thermally managed traction pack, so at 3.8 miles per kWh (235 miles for 62kwh pack) that’s 940,000 miles battery life. A drop in capacity will probably happen a bit before this but still even at 2,000 charge cycles you’re looking at 470,000...

    MG ZS EV Granny Charging at a Camp Site?

    I’ve never had a problem charging my electric vehicles at campsites in 9 years of ev camping trips. If they have a poor electric hookup network then they will have problems with camper vans plugged in too, most sites are 16amp and granny charging pulls 8-10amps so less than a traditional camper...

    Zs Cabin constantly steaming up

    Cracking the windows open a bit with the fan on screen (aircon and heat) helps to push the moist air out of the cabin quicker. Both my ZS and MG5 clear misted windows fast with aircon and heat on, I live next to a river and lake and have a big German Shepard in the boot too. New vehicles need...
