Getting questions & comments connected to lower charging speed when comparing Enyaq iV built before summer 2021 and after the SW update to ME3. Let me explain what happend with your car and how we optimized your driving experience in winter. 1/7 @skodaautonews
Do you remember your first winter with Enyaq iV? I do🤖 very high consumption and low range comparing to normal temperature. What was the issue here? The battery system was optimized to heat the battery to around 10 degrees. It means that always when you start to drive 2/7
and outside temperatures were around 0 or below. The car start to heat the battery and your consumption went rocket high. This happend always when the battery went below the target temperature. So the energy was used not only for driving but also for heating the battery. 3/7
On the other hand when you arrived at the charging station your battery was pretty much heated and you start to charge with nice speed. Depends on the SOC and charging curve. During winter plenty of customers were complaining about the consumption and range. 4/7
We started to work on optimization of the consumption and range. From production summer 2021 we change the algoritm and start to heat the battery to just above 0 degrees. The consumption went down significantly. I can see customers driving with around 20kWh/100km in winter 5/7
When you heat the battery only just above 0 degrees and you arrive to charging station with more than 25% of SOC. The charging station is heating the battery (to 23 degrees) and charging at the same time. The charging speed is bit lower due to charging curve of the battery. 6/7
My personal recommendation would be: Always set your departure time. Arrive at the charging station in winter season with lower SOC (I do it below 10%), drive faster few km's before charging station to heat the battery. Here is my charging curve from recent trip to Frankfurt 7/7

SKODA #EnyaqiV drivers are questioning when orange & red 🐢turtle is coming out and why. All is connected to a battery temperature. First you will see orange turtle, when the temperature of battery is above 0 degrees, you can experience it from below 15% SOC to 5% SOC. 1/x Image
If the temperature of battery is below 0 degrees you can see orange turtle already around 25% SOC = Limited driving speed max. to 100km/h and slower acceleration. Colder the battery and lower SOC the weaker the power output to prevent battery life cycle and longer range. 2/x Image
Red turtle is coming out when the temperature of battery is above 0 degrees and below 2% to 10% SOC. If the battery temperature is below 0 degrees you can experience it already at around 20% SOC but that would be in very cold countries. What does it mean for you? 3/x Image
