Are there charging piles in highway service areas now?
1 Answers
Currently, most highway service areas are equipped with charging piles. Here is more information about charging piles: Charging time: With current battery technology, even fast charging takes 30 minutes to reach 80% of the battery capacity. Beyond 80%, to protect battery safety, the charging current must be reduced, making the time to reach 100% longer. Additionally, in winter when temperatures are lower, the battery requires a smaller charging current, which further extends the charging time. Charging modes: A vehicle can have two charging interfaces because there are two charging modes: constant voltage and constant current. Typically, a combination of constant current followed by constant voltage is used for higher charging efficiency. Fast charging is quicker due to variations in charging voltage and current—the higher the current, the faster the charge. When the battery is nearly full, switching to constant voltage helps prevent overcharging and protects the battery.
