BMW ELECTRIC CARS.

Temperature is a key external factor that affects a battery's performance and capacity. This is no doubt a factor you may have experienced with your mobile phone: its capacity is also limited in very cold temperatures. It's the same with your vehicle. The influence of temperature is minimised by optimised operating strategies, however. 

And did you know that the battery capacity also indicates your possible available range? Apart from the temperature, the range is largely affected by your personal driving style, and also by energy consumption factors, such as the air conditioning, trailer load, luggage etc. By far the most important factor in terms of driving style is your chosen motorway speed.

If you need to charge on the go, your BMW electric vehicle will be preconditioned when you enter a DC charging station^[1] as your destination. This means that the high-voltage battery will be adjusted to the optimum operating temperature when you reach your destination, which will increase its charging capability and shorten the charging time.

If you need to park your vehicle for a long time, say when away on holiday, there are different factors than can have a positive effect on the battery: maintain a charge of between 30 and 50% and park your car in a cool place or in the shade in summer, and in a garage in winter. Do not leave your vehicle plugged in to charge for longer stationary periods.

Electric cars are considered environmentally friendly by the public because, unlike combustion engine cars, they do not produce exhaust emissions locally. However, looking at the entire life-cycle of an electric car paints a different picture: CO2 emissions and pollutants are generated in the raw material supply chains and during production of the vehicles. The type of electricity used also needs to be taken into account. Due to the energy-intensive production of the high-voltage battery, a finished electric vehicle has a higher carbon footprint than a comparable combustion engine model. This balance only shifts in favour of the electric car during its use. You can further improve your vehicle's environmental footprint by charging your electric car at home with green power such as using electricity from your own solar panels. Once you consider the whole life-cycle of an electric car, its global warming potential is lower than that of a comparable combustion vehicle.

You also need to consider the efficiency of your drive system. Here, efficiency means the percentage of the energy supplied that is actually converted into the required form of energy. The electric drive system in the current generation of BMW electric cars has an efficiency of up to 95%.^[1] However, the efficiency falls to around 75% if the driving cycle prescribed for the EU (WLTP) plus charging losses and battery depletion are also taken into account. So when driving a BMW electric car, around 75% of the energy charged is actually used for forward motion. Under comparable conditions, a petrol engine car has an efficiency of about 20%. Furthermore, electric cars have the advantage that they generate minimal noise, and so are less stressful for people and animals.

The ideal charge is between 10 and 80%. A lower or higher charge is possible, but a charge range of between 10 and 80% is recommended to optimise the service life of your battery. Simply and conveniently set your charging target to 80% in your vehicle menu, and let your car do the rest. 

A charging target of 80% will cover all your everyday trips. And when you really need more range, you can just set a higher charging target.

Electric cars work by receiving energy from the battery, which is converted into power by an electric motor. This power is used to drive the wheels. An electric motor generates more torque, and eliminates the need for a traditional transmission and so the power goes straight to the wheels for instant acceleration.

Electric cars do not have a gearbox or clutch, as they use motors instead of engines.

As electricity is not a fuel it has no scale charge,  drivers of 100% electric cars are exempt from fuel benefit tax.

You can tow with an electric car, please visit the BMW Configurator to discover if your preferred BMW model has the option of a Towbar available.

Yes, after three years of owning any new BMW vehicle you should book in for an MOT test. Following that, you will be required to book in an MOT every year moving forwards.
