The complete system torque is obtainable even at idle velocity – 500 Nm within the 270 kW variant and 450 Nm for the 220 kW variant. The ability electronics (pulse inverter) used within the plug-in hybrid fashions of the A5 are a brand new improvement. The heartbeat inverter is smaller, lighter, and extra environment friendly, thus lowering electrical consumption. Consumption in hybrid mode is subsequently additionally decrease.
Battery capability and vitality density considerably elevated
The center of the brand new A5 plug-in hybrids is the brand new high-voltage battery (HV battery) on the rear of the car. At 25.9 kWh (20.7 kWh web), Audi has elevated its capability by roughly 45 p.c as in comparison with its plug-in-hybrid predecessor, the A6 TFSI e. In distinction, the required set up area has solely elevated barely in view of the considerably elevated capability. The HV battery measures 992 × 996 × 177 millimeters (39.1 x 39.2 x 7.0 in). The additional developed and considerably optimized interplay between the mechanical friction brake and vitality restoration through the electrical motor has additionally elevated regenerative braking efficiency.
The battery cells for the A5 e-hybrid are organized in a single layer as a result of obtainable area within the rear part of the automobile. Every prismatic cell shops roughly 46 p.c extra vitality than the cells beforehand utilized in low-floor automobiles within the C phase. The cells every have a cost capability of 70 ampere-hours (Ah). The uncooked materials composition of the cells permits for increased vitality density. The battery’s vitality is bundled into 17 cells, referred to as stacks. Six of those stacks kind a unit and are linked in sequence.
So far as the association of the battery cells is worried, Audi is pursuing a brand new strategy with cell-to-pack. On this course of, the cells are not positioned in a battery module however are glued straight into the battery housing. The ensuing increased packing density signifies that the vitality content material and vitality density of the HV system could be elevated whereas taking over much less area. Because of additional technical developments in cell chemistry, increased electrical output is obtainable in comparison with the earlier technology, even at a low state of cost and low outdoors temperatures.
The utmost doable AC charging energy has been elevated from two-phase 7.4 kW to three-phase 11 kW, relying on the respective infrastructure. With this elevated energy, the HV battery’s zero-to-100-percent charging time is lowered to only 2.5 hours. A charging cable (mode 3, plug sort 2) for handy charging at dwelling and on the highway is included as commonplace. Audi’s personal charging service, Audi charging, gives entry to quite a few AC charging factors in 29 European international locations on request.
Extra vitality restoration in overrun and braking mode
In comparison with the PHEV predecessor technology of the A6, Audi has considerably elevated regenerative braking efficiency within the new A5 e-hybrid. The PHEV mannequin basically tries to drive on electrical energy for so long as doable and to completely make the most of the obtainable battery cost en path to the vacation spot. The effectivity of the plug-in hybrid drive relies on the phases by which the driving force takes their foot off the accelerator. In such conditions, overrun recuperation is managed through an outlined deceleration relying on the chosen drive degree. As well as, automated recuperation could be preset within the MMI in drive ranges D and M. The car varies the recuperation autonomously. The parameters for this are route information saved within the navigation system, comparable to gradients, curve radii, place-name indicators, and velocity limits. One other vital issue is the visitors forward. As quickly as automated regenerative braking is chosen, predictive indicators are fed into the overrun regenerative braking operate with the assistance of Predictive Effectivity Assistant (PEA). The brand new A5 e-hybrid may carry out automated regenerative braking with out energetic route steering.
When the brake pedal is depressed throughout deceleration, the A5 Avant e-hybrid quattro and the A5 Sedan e-hybrid quattro can get well as much as 88 kW of energy and feed it into the HV battery. When operated as a generator, the electrical motor accounts for greater than 90 p.c of all deceleration processes. The built-in brake management system with mixing functionality (iBRS) ensures pressure-free braking and the absolute best vitality restoration. The hydraulic wheel brakes are solely used for more durable braking maneuvers. This has no impact on the braking really feel for the driving force, because the brake pedal and brake hydraulics are decoupled.
Recuperation degree adjustable through steering wheel paddles
Because of the brand new E3 electronics structure used within the Premium Platform Combustion (PPC), the diploma of thrust recuperation in electrical driving mode (EV mode) could be adjusted to a few completely different ranges utilizing paddles on the steering wheel, identical to within the all-electric fashions. The left paddle (minus) is used to pick electrical braking and corresponding recuperation degree. The precise paddle (plus) can be utilized to scale back the recuperation degree. The paddles can thereby be used to set a better degree of deceleration earlier than a flip, for instance. At degree zero, the plug-in hybrid coasts freely with out extra drag torque when the foot is taken off the accelerator pedal. Which means that vitality is barely recovered when the brake is utilized.
Clever working technique for optimum effectivity
Two working modes can be found within the new A5 PHEV fashions: “EV” and “hybrid.” In EV mode, the PHEV fashions run on electrical energy. The combustion engine is barely turned on within the following conditions: intentionally deselecting EV within the change bar under the panoramic show or through the MMI; in driving program S; through the chosen mode of the Audi drive choose dynamic dealing with system; or when beginning route steering with hybrid help activated. If navigation route steering is activated, the hybrid assistant takes the route information under consideration when deciding on the drive mode. The combustion engine additionally engages throughout kickdown, and EV mode is deactivated till the kickdown motion is over. If none of those conditions happen, the brand new PHEV fashions use the HV battery in EV mode till it’s fully discharged. The digital slider used to manage the specified state of cost through the MMI in hybrid mode can’t be operated in EV mode; that’s as a result of the battery cost will likely be absolutely utilized in electrical mode. In EV mode, car velocity is restricted to 140 km/h (87 mph). The PHEV fashions could be began both in EV or hybrid mode, and the mode used final will likely be set because the default for when the car is began subsequent.
When driving in hybrid mode, the hybrid administration system maintains the battery’s state of cost on the obligatory degree to save lots of sufficient electrical vitality for later use, for instance for electrical driving within the metropolis. The A5 Sedan e-hybrid quattro can drive as much as 116 km (72.1 mi) on electrical energy alone based on the WLTP EAER Metropolis worth.
In terms of efficiency-optimized consumption, hybrid mode is best for each brief and lengthy distances. Relying on the driving scenario and the driving force’s energy wants, the working technique decides whether or not to drive in electrical or hybrid mode with a purpose to be as environment friendly as doable. The PHEV mannequin prefers to drive on electrical energy in city areas. At increased speeds, the proportion of hybrid driving will increase. With energetic route steering, the working technique takes the deliberate route into consideration; the absolute best vitality configuration for the specified route is robotically chosen. To attain the very best effectivity, the car calculates which elements of the route are appropriate for electrical driving. For instance, electrical driving is preferable the place speeds are more likely to be low, comparable to in city areas and visitors jams. When the hybrid assistant is activated and route steering is on, settings comparable to the specified cost degree will likely be overwritten to make sure an environment friendly working technique.
On prime of the automated hybrid mode, the specified cost degree can now be individually set for the primary time utilizing a digital slider. Drivers can use it to exactly outline how excessive the cost degree of the HV battery ought to be. The cost degree can be set earlier than your journey, in order that there will likely be sufficient vitality obtainable for electrical driving on the vacation spot if that’s the case desired or if there is no such thing as a charging choice there.
The specified cost degree could be set in outlined steps utilizing a digital slider on a share scale. If the goal state of cost (SoC) worth is under the precise SoC worth, the battery will likely be discharged all the way down to that worth. If the goal and precise values match, energy will primarily come from the combustion engine to take care of the SoC. If the goal SoC is above the precise SoC, the car will likely be powered by the combustion engine to recharge the battery.
The battery is charged with a view to maximizing effectivity and minimizing environmental affect. Which means that the combustion engine solely prices the battery at speeds above 65 kilometers per hour (40 mph); at low speeds, the cost degree is just maintained. This maximizes effectivity and permits partially electrical driving within the metropolis or in stop-and-go visitors. The battery could be charged on this means as much as 75 p.c. This ensures that the battery is charged with most effectivity whereas driving. To extend the battery’s cost above 75 p.c, an exterior AC charging supply is required.
