The glossary.

New technologies, new terms: See the highlights Audi e-tron has on at a glance.

Battery electric (BEV)

Battery electric have a battery as the sole of energy, in contrast to hybrid and extender vehicles. The Audi Audi e-tron is a BEV.


Electric motors are in their high reliability, low and high efficiency. They consist of a moving part rotor) and a fixed component stator). The stator generates a magnetic field that a force on the rotor, thereby it in motion. Electric drive in vehicles are generally fluid-cooled.

types of three-phase motors are used in vehicles from Asynchronous motors (ASM) dispense with permanent are simple in design, sturdy, little maintenance and have lifetimes. Permanently excited motors (PSM), on the other require a more complex system. They are more and lightweight in design; they offer advantages in terms of usable rev range and efficiency.
In vehicles like the Q5 hybrid, uses a high-torque PSM integrated in the

It has a relatively large diameter for a torque, and yet is short in length; its speed lies between 2000 and 7000 rpm. For electrical vehicles the high-rev of PSMs and ASMs are suitable – attain rated speeds 10,000 and 14,000 rpm and have diameters, and yet are longer in length. One can be omitted, however.


The specific energy is the amount of that a battery can store per of mass; it is measured in kilowatt-hours per kilogram of weight. At present batteries have a specific of about 130 kWh per kilogram.
In view of progress, Audi experts an energy density of 2500 Wh per kg to be by 2020, which is also the upper limit for lithium-ion

By comparison: one kilogram of gasoline 1.33 liters (0.35 US contains about 12,000 Wh of

e-tron quattro

Audi the term “e-tron quattro” to the next-generation quattro drive It combines the strengths of the proven drive with the potential by electric mobility. The fully or electric quattro drive extra-efficient operating modes and up new possibilities for quattro handling

Hybrid vehicle (HEV)

Energy recovery and start-stop reduce the CO2 emissions.

Mild a mild hybrid, the electric supports the combustion engine in to boost the power output.


In full hybrids as the Audi Q5 hybrid quattro, the motor can propel the car independently for periods.

Plug-in hybrid

The hybrid is capable of travelling electrically over longer The battery can be charged directly a mains socket.

Hybrid Cell (HFC)

The power for the drive systems of the future can be from the mains – but it can also be on board the vehicles themselves the help of a fuel cell uses hydrogen as a fuel. The sophisticated version to date of a hybrid drive is showcased in the Q5 HFC technology study. The three in the study’s name stand for Fuel Cell.

Two high-pressure cylinders hold a of 3.2 kilograms of hydrogen pressurised to 700 The low-temperature hydrogen-based fuel-cell has an output of 89 kW (120 bhp). The battery used for hybridisation, is also employed in the Audi Q5 quattro, has an energy content of 1.3

Drive power is provided by two motors close to the wheels, can generate a peak joint of 90 kW (122 bhp) and up to 420 Nm of torque. The Q5 HFC accelerates to 100 km/h from in 13.4 seconds and attains an limited top speed of 160 km/h.

efficient use is made of the hydrogen – the fuel cell drive has an factor of over 50 percent. results in an operating range of up to 250 Once the hydrogen tanks can be designed and integrated into the ranges of 500 km are a realistic possibility.

Audi e-gas

Refuelling takes no longer on vehicles with conventional systems.

Charging technology

In hybrids and strictly electric the battery is basically recharged apart from in braking recuperation and load point The on-board charger converts the current from the public to direct current for the battery. a 400 V three-phase current and higher current the charging time several times over with a 240 V household current. As an solution, Audi is working on charging by induction and on quick with direct current and output.

This technology a further reduction of the charging

Load point displacement

vehicles like the Audi Q5 quattro are usually powered by the engine outside built-up The hybrid manager controlling the of the drives makes sure the TFSI temporarily has less of a in the low rev range than is required for the – the load point is shifted to a range, and efficiency improves. The torque benefits the electric which then serves as a and recharges the battery.

Battery lifetime

The lifetime of a battery is greater than ten assuming that the battery at moderate temperatures. The load and the intensity of the charging and discharging critically affect the lifetime. For reason batteries in hybrid like the Q5 hybrid quattro are discharged only to about 50 per of their energy content in electric vehicles 20 per cent is the lower limit.

The operating that controls the vehicle the permissible load limits.

design for hybrid and electric

The special components of an electric or car unavoidably add to the vehicle’s weight. keeps the overall weight limits, however – the increase is more than 100 kg (220.46 lb) in the Q5 quattro and A1 e-tron. In developing mobility, the Four Rings profits from its comprehensive lead in lightweight design.

In its competitive environment the Q5 is a benchmark for design in this vehicle The aluminum bodies with the Space Frame(ASF) design and the new plastics contain great in this regard.
