Model Short-Circuit Fault in EV Charging Cable
Model and prevent a short-circuit fault in the connectors of an electric vehicle (EV) charging cable. First, you examine the system under normal operating conditions with effective refrigerant cooling and a constant-current (CC), constant-voltage (CV) charging strategy. Then, you introduce an open-circuit fault in the motor of the refrigeration system. This fault causes the cable to overheat, resulting in the short-circuit fault in the cable connectors. Finally, you regulate the current to enable passive cooling and safer battery charging without relying only on the refrigeration system.

Automotive Alternator Charging a Battery
How alternator behavior can be abstracted to a DC model that simulates efficiently. This test harness first ramps the alternator speed linearly from zero to a typical idle speed of 900 RPM. When the generated voltage is sufficient to overcome the forward voltage drop associated with the rectifier diodes, the battery charging current starts to ramp up. The test harness then ramps up the speed to 5000 RPM, and the alternator has to back off the field voltage to maintain the regulated voltage. The model captures the increase in stator resistance as the alternator heats up, this reducing device performance

An interior permanent magnet synchronous machine (IPMSM) used as a starter/generator in a simplified 48V automotive system. The system contains a 48V electric network and a 12V electric network.
