As electrification accelerates, the automotive industry faces unprecedented challenges.

As the market for EVs continues to expand, there is an urgent need for efficient energy management and safety as well as improved battery performance. Rapid battery charging, thermal management, and compliance with safety standards, as well as balancing comfort and range, are key challenges for all EV developers.

The need to prevent thermal runaway and degradation of batteries and to increase safety while extending their life is growing in proportion to the expansion of the EV market. The key to solving these technical challenges and bringing the next generation of EVs to market is to utilize advanced simulation technology from the design stage. How can state-of-the-art simulation tools be used to overcome design and technical challenges in EV development? Optimization topics to accelerate the development of next-generation EVs for automakers, battery developers, and those involved in energy management are common challenges in other industrial sectors and will serve as a reference for engineers working in a variety of industries.

For example, the challenges of battery thermal management, the impact of battery insulation and BMS strategies on charging time from fast charging simulations, and the impact of busbar parameters on battery performance from busbar simulations are design and thermal engineering challenges that can be addressed with advanced CAE simulations.

Simulating GB 38031-2020 tests in thermal runaway, improving thermal management to optimize battery life, and avoiding downgrades with high voltage cable simulation are all safety and durability solutions in EV development through simulation.

These are integrated vehicle energy management that combines 0D, 1D, and 3D, and simulation is used to solve vehicle energy management issues such as the integration of PV panels, heating and cooling functions in vehicles and the balance between comfort and range in EVs.
