Solutions
GT-SUITE unifies battery, motor, thermal management, and controls simulation in a single environment, optimizing energy management, performance, and efficiency across the full EV and HEV development cycle.
Solution Overview
GT-SUITE offers advanced data and model management features, which allow you to publish libraries of components and subsystems for fast and efficient vehicle architecture studies. With GT-ISE’s object-oriented interface any electrified vehicle architecture can be built and tested for various objectives, like mileage, performance, emissions, component matching, total cost of ownership and the derivation of subsystem requirements.
After the vehicle architecture has been determined, GT-ISE’s enables the easy integration of physical subsystems, including but not limited to thermal management and aftertreatment systems. This allows for both the integrated development of subsystems and components and the optimization of full-vehicle energy and thermal management strategies.
As the vehicle development progresses, even more advanced analyses of electrified vehicles can be performed, including dynamic analysis of electric boosting systems with GT-POWER, NVH and drivability studies, and detailed battery, engine, and motor heat distribution.
Application Highlights
Purpose-built tools for architecture optimization, battery modeling, thermal integration, and regulatory compliance, enabling deeper insight into performance, efficiency, and drivability.
Evaluate vehicle architectures, components, and control strategies using built-in optimization and Design of Experiments (DOE) tools, without requiring external software. Accelerate design decisions and identify optimal configurations earlier in the development process.
Access a comprehensive library of Lithium-Ion cell models to accelerate battery system design and reduce reliance on physical testing. Supports accurate prediction of range, performance, and state-of-health across electrified vehicle platforms.
Integrate electrically heated catalysts into full-vehicle simulations to quantify the trade-off between fuel economy and emissions performance. Enables informed system-level decisions during hybrid powertrain development.
Couple vehicle thermal management systems with energy management strategies to ensure proper component temperature control and cabin comfort simultaneously. Enables holistic optimization across powertrain, battery, and HVAC subsystems.
Combine GT-POWER's 1D airflow and combustion models with electrified vehicle simulations for precise engine transient response. Refine engine controls and electric boosting strategies together in a single, unified environment.
Configure and run event-based vehicle testing procedures aligned with regulatory standards, including EPA 5-cycle and WLTP protocols. Streamlines compliance validation and enables direct comparison of simulation results against certification requirements.
Common questions about simulating hybrid and electric vehicle systems, from architecture modeling to drive cycle testing.
GT-SUITE covers the full range of electrified vehicle architectures, from mild and full hybrids to plug-in hybrids, battery electric vehicles, and fuel cell electric vehicles. Whether you are working with a series, parallel, or power-split topology, the platform gives you the flexibility to build and test virtually any driveline configuration without being locked into predefined templates.
Yes. GT-SUITE automates the EPA 5-cycle test procedure in line with SAE J1634, covering the Multi-Cycle Test, Short Multi-Cycle Test, and standalone 5-cycle test. Rather than running manual, iterative calculations, engineers get a streamlined, repeatable process that takes them from simulation directly to label range prediction, which matters a great deal when certification timelines are tight.
GT-DRIVE+ lets engineers rapidly evaluate motor configurations, size batteries and motors, and generate efficiency maps, all within one environment. The built-in optimizer can sweep through hundreds of design combinations automatically, helping teams hit performance targets like acceleration and fuel economy well before any hardware is built.
It can. GT-SUITE connects with traffic simulation tools such as SUMO through a Simulink co-simulation interface, allowing engineers to study powertrain behavior in realistic, unpredictable traffic conditions. This means you can account for variable driver behavior, vehicle interactions, and physical constraints like battery limits and motor torque, all in a single, integrated simulation.
