As electrified vehicles become more sophisticated, the complexity of VTMS sub-systems has increased. Unlike with combustion powertrains, VTMS must consider batteries, electric motors, inverters, and cabin HVAC systems.
This requires integrating multiple, interconnected thermal loops that operate simultaneously and minimize energy consumption. Innovations such as heat pumps, liquid cooling systems, and waste heat recovery add to this complexity by requiring precise coordination between hardware and intelligent software controls.
The challenge is compounded by the need for compact designs, dynamic adaptation to varying conditions, and compliance with stringent environmental standards. Simulation tools can play a crucial role in addressing this complexity by allowing engineers to model, optimize, and test VTMS configurations virtually, leading to more efficient and reliable designs.
Manage Complex Thermal Interactions
The integration of multiple heat sources like batteries and electric motors requires managing complex thermal interactions. Simulation allows you to model these interactions, ensuring efficient heat distribution and system reliability.
Optimize Energy Consumption
Balancing the energy demands of various thermal loops is crucial for efficiency. Simulation enables you to test different configurations and control strategies, optimizing energy consumption while maintaining performance.
