Introducing Ansys EMA3D Charge – Charging and Discharging Modeling Solution

Electrification creates new requirements for high-voltage batteries and power systems as part of everyday life. Autonomous vehicle systems must retain their safety-critical functions when exposed to static discharges within their normal operating environment. In space exploration, providing greater connectivity and accessibility is required. These three technological developments require a deep understanding of electrical charging and discharging phenomena. Preventing catastrophic failures of products due to charge and discharge events must be tackled. Until now, product design teams did not have any means to simulate charging and discharging events. Engineers want to use simulation to optimize product design when changes are less costly and before production ramps up.

Ansys EMA3D Charge is a brand new, 3D simulation product that meets these needs. It simulates spacecraft charging effects, electrical arc on high voltage systems such as busbars and cables, non-contact ESD (electrostatic discharge), dielectric breakdown, among several other applications.Highlighting critical applications of Ansys EMA3D Charge, we'll introduce the technology used to simulate ESDs in air and solids, surface, and internal charging.
