Training

The 2.0 TFSI Audi Q5 Hybrid is a displacement of 1984 cc. Its output is 155 kW (211 hp) and torque of 350 Nm (258.15 pounds-ft) available constantly from 1500 to 4200 rpm. four-cylinder petrol unit combines direct injection with turbocharging. Audi valve lift system (AVS), in addition to more power, torque and efficiency of connecting a cylinder exhaust valves in two stages depending on load and rpm.

The 2.0 TFSI has been redesigned in some respects, for use in the hybrid Audi Q5. Powered by additional units have been lost, and the crankshaft bearing and fine tuning of the turbocharger has been adapted to specific needs. A secondary air system on the yoke so that reductions in exhaust gas treatment particularly fast. Integrated into the engine control unit controls the hybrid leader, concrete changes and smooth transitions between operating modes.

Much tiptronic is changed to eight reports of power transmission without using a torque converter. His place is taken by the electric motor in a disc combined with a multi-disc clutch in oil bath, as a couple and disconnect the electric motor and TFSI. Decoupling innovative works accurately and smoothly in any situation.

The gear extremely comfortable and fast evolving hybrid contributes significantly to the effectiveness of the hybrid Audi Q5 - the eight machines are far away. When the 2.0 TFSI is disabled, an electric pump maintains oil pressure in the hydraulic system for the convenient start-stop.

Power electronics and electric motors

The radiator tank in the engine compartment houses the power electronics. The UPS allegedly controlled by the pulse controller is used between the battery, which came out in DC, and the electric motor running on AC power. Innovative technologies to maintain the volume and weight of low power electronics, with cooling provided by a separate circuit filled with water at low temperature. The component includes a DC / DC converter that couples electrical consumer electrical system 12 V high voltage.

Permanent magnet synchronous machine acts as an electric motor, as the starter and - during deceleration - as a charger. It offers up to 40 kW (54 hp) and 210 Nm (155.63 pounds-ft) of torque. The electric motor is integrated into the engine cooling system.

Battery

Lithium-ion battery system that weighs only 38 kg (83.78 pounds), operates in energy storage in electric hybrid Audi Q5. The compact unit has a capacity of 26 liters (6.87 gallons) is placed in a forced landing in a secure area of ​​the load with virtually no damage to the luggage compartment. The battery consists of 72 cells, 266 volts at a nominal energy of 1.3 kWh and the power of 39 kW.

Lithium-ion battery is cooled by air in two ways, as needed. At low temperature impact, draws air from the temperate interior of the shape of a fan. If the temperature exceeds a certain limit is a separate cooling circuit activated. It is connected to the main climate control system of the vehicle and uses a separate evaporator. This mechanism of active cooling is effective in a major electric hybrid system for high availability and enables the quattro Audi Q5 Hybrid is distinguished from many other hybrid cars.

Operating Modes

Audi Q5 hybrid four can run five operating modes. Drive a combustion engine alone, the use of electricity alone or in hybrid mode, it is possible, as well as recovery and improvement. Stalled - before or at the traffic lights, for example - is to guide the use of sources. Here's how "comfort" start-stop, the air conditioner is turned on. When the driver releases the brake, Four Q5 hybrid will start coasting. You can drive up to 100 km / h (62.14 mph), the electricity - almost without any noise or local emissions. At a constant speed of 60 km / h (37.28 km / h), is a series of 3 km - sufficient for many residential areas and city centers.

The driver can switch between the three programs using a button on the console shifter or. EV short feature priority to the electric car in town, the D mode controls both engines to the optimal consumption and the S mode and touch the door tiptronic is designed for sporty driving style.

If the driver accelerates rapidly, the internal combustion engine takes over and provides traction. Now the main task electric motor is to run the high-consumers and keep the battery charged. In hard acceleration, or "promote", electric motor drives with TFSI, with full power mode S card output system available. In such cases, provide a hybrid large naturally aspirated engine, but with greater efficiency.

When the driver releases the accelerator, the electric motor acts as a generator and battery power is restored. In most situations, the TFSI is then disconnected from the system unit to cause no accumulated losses. The power recovered by the electric motor and braking here protects the lithium ion batteries. If the driver brakes a bit, the electric motor itself provides the strongest deceleration brake hydraulic brake system is activated at the same time.

Use of the vehicle

The Audi Q5 Hybrid is a novel display concept, which can be every mode of behavior of the hybrid car lived. The tachometer has been replaced on the scoreboard with a "power" with a needle that indicates the total output of the system on a scale of 0 to 100. A second scale is divided into colored segments, greens and orange segments clearly indicate that the hybrid drive system Q5 quattro is currently using. An additional instrument shows the level of battery charge.
