The main reasons why DC charging cabinets cannot operate independently are as follows:
- DC charging cabinets rely on the power grid for charging and cannot be charged offline.
- The distribution network is not specifically designed for onboard charging services. Grid parameters such as voltage and frequency may not meet the operating requirements of charging piles, resulting in charging piles being unable to operate independently.
- Bandwidth and capacity factors limit the interaction methods of charging piles, making them more dependent on internet connections.
