Electrification / 46 SIMULATION SOLUTIONS Vehicle System Injection Nozzle Flow, Cavitation and Erosion Combustion and Emissions Turbocharging Exhaust Gas Aftertreatment Transmission and Driveline Durability and NVH Electrification Thermal Management and Aerodynamics Calibration and Testing Quenching TEST SYSTEM SOLUTIONS TESTING EQUIPMENT SIMULATION TOOLS TESTING TOOLS CUSTOMER SERVICES The simulation of vehicles with different levels of electrification (from HEV to PEV), the optimization of electrical systems and their components (such as electric drives, batteries and fuel cells) under completely new operating conditions and improvement in the performance of electrical turbochargers are just a few examples of AVL’s innovative simulation capabilities in the huge field of new and challenging technology trends. HIGHLY DETAILED NVH ANALYSIS OF ELECTRIFIED POWERTRAINS AVL EXCITE’s domain is a detailed component and system analysis in terms of the dynamics, strength, durability and acoustics of hybrid powertrains and gen-set configurations. Analysis targets are Dynamic analysis of hybrid powertrains – interaction between e-machine and IC engine (AVL EXCITE) e.g. the detailed investigation of the interaction between e-machine and the cranktrain of belt-driven starter-generator or mild hybrid systems, the dynamics and NVH of transmissions under combined non-stationary loading conditions or the influence of grid connection maneuvers on the dynamic behavior and load conditions of gen-sets. OPTIMIZING ENERGY STORAGE AND COOLING SYSTEMS AVL FIRE® makes it possible to predict the overall behavior of a Li-lon battery cell, module or complete battery during transient charging and discharging processes. Critical conditions can be identified, thereby helping to optimize the system in terms of electro-chemistry, performance and thermal management. In order to accomplish these tasks, AVL FIRE® offers thermo-electrical as well as predictive electro-chemical battery models which enable the simulation of electric charge transport in active layers and positive and negative collectors as well as heat conduction in thermal masses, while considering electric and thermal contact resistance.
