There are a number of global standards for EV charging, such as SAE-J1772 (North America), GB/T 20,234 (China), and IEC-62196 (Europe), which specify different AC and DC charging modes. As a result, these standards differ in their voltage, current, and power limits, with DC fast charging providing the highest power output. 6.
An overview of different charging systems in terms of onboard and off-board chargers, AC-DC and DC-DC converter configuration, and AC and DC-based charging station architectures are evaluated.
The main difference between these three standards is that the first two classify charging modes in accordance with the power type (DC or AC), while the third classifies charging modes in accordance with the charging power .
Combined Charging System (CCS) stands as a foundational standard for charging electric vehicles, including AC and DC charging, communication between EV charging stations and cars, load balancing, authentication, authorization to charge, and vehicle couplers (connectors at the end of charging cables and corresponding inlets in vehicles).
Preventing thermal runaway and fire dangers while preserving performance is critical for consumer trust and regulatory compliance. − A battery’s capacity, performance, and safety are all affected by the charging and discharging techniques. As a result, charging and discharging pose a significant challenge.
