C h a p t e r 3 While many different subsystems are vital to EV performance, few garner the same amount of attention as the charging system. EV charging as a whole relies on several closely connected systems and subsystems both on and off the vehicle. For instance, electric vehicle supply equipment (EVSE) (i.e., charging stations) consists of multiple well-engineered parts including the power socket, which is optimized for safe and accurate power delivery, as well as a smart controller for control, security, and connectivity. Between the EVSE and the vehicle itself, one expects to find hardware such as microcontrollers, application processors, secure wired and wireless connectivity modules, AC/DC converters, DC/DC converters, and regulators, power management integrated circuits, and battery management systems (BMS). Since a full EV charging system consists of so many seemingly disparate components and subsystems, interoperability becomes a significant design concern. In order to achieve the best efficiency, performance, and flexibility, the charging station circuitry must be highly compatible with the on-vehicle charging circuitry. Functions that require high levels of interoperability include accurate power delivery measurement, secure data communications, and cloud onboarding for applications like vehicle-to-grid. However, achieving this level of device interoperability is a challenge for EV charging solutions because charger DESIGNING EV CHARGING SOLUTIONS Alexandra Dopplinger Global Industrial Marketing Manager, NXP Semiconductors When you consider an EV charging solution, you realize that it encompasses so many different aspects—a power side, a control side, and a communication side—as well as presents safety concerns, interoperability concerns, and regional concerns." 13 7 Experts on Designing Vehicle Electrification Solutions
