Hi has anyone had an issue with the displayed battery mileage after a full charge. I had my mg ZS ev in December last year and have now changed it twice with the home charger from BP chargemaster.
The two times I have used the home charger it only displays around 140 miles of battery worth. It says 100% charged. But the shown mileage should show at least 163 miles as stated by MG . Or is this wrong I have not tried to charge the car anywhere except at home . A very confused MG owner.

The range display is commonly referred to as the GOM, or guess-o-meter. It's based on real world factors like your driving style, the use of the heater, the outdoor temperature etc.

EVs aren't as good in the winter as the batteries can't perform at their best in the cold and using the heater takes even more range away. But in the summer you'll see this rise further, likewise with careful driving you can also make it give you more.

It doesn't sound like anything is wrong with your car.

The figure of 163 miles is the mileage that the vehicle could achieve when driven to the procedure of the WLTP test programme.
You can read about the WLTP test method here Worldwide Harmonised Light Vehicles Test Procedure - Wikipedia

The idea of the WLTP value is to be able to compare different cars all tested in the same way.
It is not a guaranteed value for any journey. This is because different journeys by different drivers can have different hills, different speed limits, different driving styles etc. And the weather also affects the result as well - headwinds / rain / air temperature all have an effect.

The range shown in the car is based mainly on the miles achieved per battery kWh for recent travel in the car influenced by your driving style and use of heating and the weather conditions.

Many thanks for your input to my question. I’ve been driving the car on eco mode since brought and on level 3 regenerative braking to try and get the car to do more. clearly it hasn’t worked. I might as well drive in normal mode as it only makes a difference of approximately 10miles more and enjoy driving it.

Yeah unless you're doing humongous miles drive it like you would your ICE. There's no point in being cold and uncomfortable whilst you've got more than enough miles to do your journey. I learned that the hard way when I drove from Stoke to London and back in Feb 2016 with my wife and daughter. Drove it in Eco mode, which shuts off the heater in the Zoe. Didn't get back home until 2am. Tired and very, very cold. I swore then that I would never use Eco mode again.

Today for example I drove 65 miles in temperatures between -1°C to-2°C with a moderate breeze, which for half the journey was a headwind. I used 55% of the battery. The car reported that I had 52 miles remaining. That feels about right, about 117 miles added up together.

For this time of year that is about right! I’ve never yet managed to physically drive 163 or more miles on one charge, but some owners have! But will be in warm dry still weather.

Typically I got 140-150 miles in the summer. I drive year round in Normal with Kers 3. I don’t personally see the point in Eco. You can get the same results with careful driving.

In winter I always recon on 100-120 miles depending on the conditions.

All the above is my experience too, but on one hot day I drove 80 miles down a windy road at 50 mph max averaging 35 and achieved 5 miles per kWh or 200 plus miles. That would be normal mode KERs 3 and the sort of driving you would when touring.
