The Golf Family Grows

Dr. Heinz-Jakob Neußer on the new e-Golf

Following the e-up!, Volkswagen now launches the e-Golf, its second e-car, onto the market. For whom is this car best suited?

The e-Golf is the perfect car for people who mainly travel in urban areas or within short and medium distances of them. As a member of the Golf family, it naturally meets all safety requirements familiar from the high-volume series. Furthermore, as a 5 door car with an extensive standard, and freely selectable optional equipment, it meets all the

fort requirements expected by our

com customers in this car class. Thanks to its prac tical range of 13o to 19o kilometres, this car is not only ideally suited for family use and for commuters but is also

practical for companies operating

very

in urban areas. Here is one fact

mainly probably very few people initially expect: the e-Golf tainous and hilly areas. Hill starts and climbs can be overcome almost without effort, as well as comfortably, thanks to the high tor que of the e-engine, even when accelerating from a full stop. Electric energy is regained via recuperation during braking, hill descents or in coasting mode, and can then be stored once again in the high-voltage battery. This further improves energy consump tion and increases the avai l able range. The e-Golf can be driven comfortably and very dynamically with its energy efficient and powerful drive, combined with its low centre of gravity, due to the installation position of the high-voltage battery between the axles.

A heat pump was installed for the ﬁ rst time in the e-Golf. How does this affect consumption?

When considering that all electric

are fed by the vehicle battery, one can imagine the importance of reducing onboard power consumption as much as possible by any means. Vehicle heating and air conditioning have a substantial impact on the available range, in relation to the energy stored in the highvoltage battery, due to their high energy consumption. The innovative heat pump installed in the e-Golf utilises the thermal energy in the coolant of the e-machine engine and power electronics, to heat the car in winter or cool it in summer. The energy saved increases the available range for the high-voltage battery.

What sense does it make for Volkswagen to launch a further electric vehicle onto the market?

Last year, with the e-up!, we launched a very good and fully usable electric car onto the market.With the e-Golf, we now extend our portfolio of alternative drive vehicles by adding an electric car in the compact segment, and for the ﬁ rst time offer a fully-ﬂ edged e-vehicle in mass production. Electromobility in the Volkswagen Group has reached the centre of our Modular Transverse Matrix. By taking this step, we will be able to satisfy different customer demands and requirements in our primary markets – and across all regions.

How do you imagine charging infrastructure will develop?

Unfortunately, current developments show that the charging infrastructure is only developing very slowly. This is very regrettable because we have reached the point at which the range of electric cars with alternative drives is continuously growing. It is counterproductive if

the infrastructure does not keep up with the growing range of vehicles with alternative drives, and therefore detrimental to the economic development of the automotive industry that has made very expensive preparatory efforts. An important signal, from our point of view, is that the Transport Committee of the EU Parliament in November came out in favour of constructing 45o,ooo charging stations in Europe by 2o2o – 86,ooo of which will be in Germany alone. Currently there are about 2,2oo public charging stations in Germany. Now, concepts for their implementation have to be developed as fast as possible on both an EU and a national level, and the necessary prerequisites for a successful and quick implementation have to be created.

How will battery capacity develop? Can we expect electric vehicles to have the same range as conventional vehicles soon?

Firstly, I would like to point out that even today the daily driving ranges of the majority of our customers can be covered using the electric cars currently offered. Surveys have shown that our customers travel no more than 4o to 5o kilometres per day on average. Even to-

day, ranges of 12o to 16o kilometres with the e-up! and 13o to 19o kilometres with the e-Golf are possible. With that, individual mobility is ensured. Work on the optimisation of storage capacity is ongoing globally, in order to further increase customer utility. A noteworthy technological leap in battery development, however, cannot be expected until 2o2o, according to our estimates. Un til then there will of course repeatedly be smaller advances with the currently known battery cells. Beyond that, there are other parameters, such as lightweight construction, aerodynamics, drive technology, and onboard consumption that can positively affect the range. We attach great importance to the optimisation of these parameters during the development of our e-vehicles. As mentioned before, we will utilise an optional heat pump to improve the e-Golf ’s heating efﬁciency.

The charging process currently takes quite some time. Will one be able to charge the car more quickly in the future?

Today it is already possible to charge the battery at a quick charging station using direct current from o to 8o per-

cent of its capacity in half an hour, when using the Combined Charging Systems. With that, we are on the right path. Previously, the charging process took consid erably longer. Unfortunately, the quick charging infrastructure in Germany is still completely underdeveloped. The time has come now to faster develop the charging infrastructure in public parking spaces, if needs be by means of legal regulations – if Germany is to be the leading market for e-mobility. We offer our customers an optional Wallbox, when buying an e-car, with which the e-up! can comfortably be completely charged in six hours and the e-Golf in eight hours, in front of your own doorstep or while at work.

THE E-GOLF VIAVISION

The drive accelerates the e-Golf

The main distinction between a car with a conventional combustion engine and the e-Golf is located beneath the bonnet: the electric motor, power electronics, gearbox, and engine control unit, in combination, ensure that the e-Golf drives almost noiselessly and without emissions. In the process, the motor spins at up to 12,ooo revolutions and delivers up to 85kW/115hp. The electric drive developed by Volkswagen is part of the Modular Transverse Matrix (MQB), and is used in other models, for example in the e-up! mini car.

The Charging Unit

The charging unit, integrated in the engine com partment, transforms the available alternating cur rent into high-voltage direct current, when charging the car. The charging unit can be connected to an ordinary 23o volt socket in a domestic garage or at a public charging station. A completely discharged high-voltage battery is charged wit hin 13 hours, and in signiﬁ cantly less time with a CCS charging station using DC fast charging. Furthermore, a distribution point for the high-voltage onboard power supply is integrated into the charging unit.

The Electric Motor

Motion in the electric motor is caused by the alternating attraction and repulsion of opposing and same polarity magnets. The e-golf is equipped with a permanently excited synchronous machine with a maximum output of 85 kilowatts. The permanent magnets in the rotor, the movable part of the motor, are alternating south and north poled magnets. The stator, the ﬁ xed part of the motor, generates a rotating magnetic ﬁ eld, created by applying current to the coils. As a result of the interaction with the permanent magnets, the rotor turns at a speed synchronous to the rotating magnetic ﬁ eld of the stator. The electric engine, called a synchronous machine for this reason, also runs particularly smoothly at low speeds.
