The Audi A5 plug-in hybrid electric vehicle (PHEV) epitomizes efficiency and performance. Combining a powerful combustion engine with an advanced electric motor and high-capacity battery, the Auto A5 delivers an exceptional driving experience while minimizing environmental impact. This article explores the innovative technology behind the A5 PHEV, delving into its intelligent hybrid management system, enhanced battery capabilities, and comprehensive charging solutions.
Auto A5: Redefining Hybrid Management
The Auto A5’s hybrid system seamlessly integrates a 105 kW peak output permanently excited synchronous motor with a seven-speed S tronic transmission. This configuration ensures immediate torque availability, reaching 500 Nm in the 270 kW variant and 450 Nm in the 220 kW model. Even at idle, the full system torque is readily accessible, guaranteeing responsive acceleration and effortless cruising. A newly developed, smaller, lighter, and more efficient pulse inverter further enhances the system’s overall efficiency by reducing electrical consumption.
Advanced Battery Technology in the Auto A5
The Auto A5 boasts a significantly larger high-voltage (HV) battery compared to its predecessors. With a capacity of 25.9 kWh (20.7 kWh net), this represents a 45% increase over the previous generation A6 TFSI e. Remarkably, this substantial capacity upgrade comes with only a slight increase in installation space. The battery’s compact dimensions (992 × 996 × 177 millimeters) allow for seamless integration into the vehicle’s rear section.
Audi’s innovative cell-to-pack approach directly glues prismatic cells into the battery housing, eliminating the need for traditional modules. This maximizes packing density, boosting energy content and density within a minimized footprint. Each cell holds approximately 46% more energy than previous generations, contributing to the A5’s impressive electric range. Furthermore, advancements in cell chemistry ensure higher electrical output even at low states of charge or in cold temperatures.
Efficient Charging Solutions for the Auto A5
The Auto A5 supports three-phase 11 kW AC charging, significantly reducing charging times to just 2.5 hours for a full charge. A standard Mode 3, Type 2 charging cable facilitates convenient home and public charging. Audi also provides access to its extensive charging network, Audi charging, spanning 29 European countries.
Maximizing Energy Recovery in the Auto A5
The Auto A5 PHEV prioritizes electric driving, maximizing the use of stored battery energy. It intelligently recovers energy during deceleration and braking. The system can recapture up to 88 kW of power during braking, feeding it back into the HV battery. An integrated brake control system (iBRS) ensures seamless transitions between regenerative and hydraulic braking, optimizing energy recovery without compromising braking performance or feel. Steering wheel paddles allow drivers to adjust the level of regenerative braking, further enhancing control and efficiency.
Intelligent Operating Strategies for Optimal Efficiency
The Auto A5 offers two primary operating modes: “EV” and “Hybrid.” EV mode prioritizes electric driving, engaging the combustion engine only when necessary, such as during aggressive acceleration or when the battery is depleted. In Hybrid mode, the system intelligently balances electric and combustion engine use to optimize efficiency based on driving conditions and route data. A digital slider allows drivers to customize the desired state of charge, ensuring sufficient electric range for specific needs.
Auto A5: Luxury and Performance Combined
The Auto A5 PHEV doesn’t compromise on luxury or performance. It comes standard with a comprehensive suite of features, including progressive steering, navigation, a panoramic display, and inductive charging. Options like the business package further enhance comfort and connectivity. The A5 PHEV exemplifies Audi’s commitment to sustainable mobility without sacrificing the driving experience.
Conclusion
The Auto A5 represents a significant leap forward in plug-in hybrid technology. Its intelligent hybrid management system, advanced battery technology, efficient charging solutions, and comprehensive energy recovery capabilities combine to deliver an exceptional driving experience with minimal environmental impact. This sophisticated PHEV embodies Audi’s commitment to innovation and sustainable mobility, setting a new standard for performance and efficiency in the luxury automotive segment.
