1. Poor user experience: Long charging time will directly affect the user's experience. For users who need to frequently use vehicles, long charging wait times can cause inconvenience and reduce the overall efficiency of vehicle usage.
2. Low energy utilization efficiency: Long charging processes mean that electricity resources are occupied for longer periods of time at charging stations or home charging piles, especially during peak demand periods, which may lead to increased grid load and hinder efficient energy utilization.
3. Technical limitations and cost considerations: Long charging times are often related to the current level of battery technology and the technical capabilities of charging facilities. Although fast charging technology is constantly evolving, excessively fast charging speeds may have a negative impact on battery life and increase maintenance costs. Meanwhile, the construction and operation costs of fast charging facilities are relatively high, which may indirectly affect the popularity and cost-effectiveness of new energy vehicles.
