Fast charging is one of the biggest advantages when driving an electric vehicle. In order to really unlock the potential, especially on road trips or on busy days, you have to connect more than just. Factors such as battery temperature, load state and route planning can make a big difference in charging power – especially in models such as the BMW i4. And that is even more important in cold weather. Here you will find out how to prepare your EV for quick fees to ensure that you receive the fastest and most efficient fee.
1. Use the built -in navigation system
Before a charging station, set the integrated navigation system of your vehicle (not via Apple CarPlay or Android Auto) as the destination in the integrated navigation system of your vehicle. This is crucial because modern electric vehicles such as the BMW i4, i5, IX and i7 use this input for the prerequisite for the battery – essentially heated to the ideal temperature for fast charging.
Preliminary conditioning begins automatically when the car knows that you drive to a powerful charger. This makes a big difference in the loading speed, especially in colder weather or if the battery has not been used strongly. You will find that in cold weather it can sometimes take more than 30 minutes so that the loading speed has reached the announced capacity.
2. Activate the pre -conditioning manually (if available)
If your BMW is a newer model with a dedicated pre -conditioning option in the Lademenu, you should activate it before your arrival. This gives you more control and guarantees that the battery will be properly heated at the time of plug. Warming the battery usually takes about 20 to 25 minutes. So give your vehicle enough time to reach the right temperature on the go.
3. Try the “yo-yo method” if the preliminary conditioning is not available
Drive an older EV without built -in pre -conditioning? You can still prepare the battery manually with a technique known among EV owners as a “Yo-YO method”. Like: How:
- Put the car in the B mode (for stronger regenerative braking).
- Fast speed on a highway to a comfortable speed on a highway, then leave the car on the coast and regenerate it up to a lower speed.
- Repeat this cycle 10 times or more.
This quick acceleration and delay heats the battery by an increased energy flow and imitates the effect of a pre -conditioning system.

The loading status of your battery (SoC) has a dramatic effect on how quickly your car can charge. Here is the general rule, but of course it can vary from BMW to BMW, all based on its charging capacity and charging curve:
- The fastest charging (150 kW+) occurs between 10 and 30% SoC.
- The loading speed gradually slows down with increasing SoC.
- With 50% SOC or higher, the loading rates drop considerably.
- At 80% or more, the loading slows down significantly to protect the health of the battery.
So if you plan a quick fee, try to arrive at 20% SOC or less for optimal speed. For example, our BMW i4 200 kW receives a 350 kW charger at 20% SOC-a ideal scenario for fast top ups.
5. Plan the efficiency and time savings in advance
The combination of these techniques – the native navigation, enabling the pre -conditioning or manual heating of the battery – you can save valuable minutes in the charger and extend your area more efficiently. On long trips, this can lead to great time savings and less downtime.
