Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and specifically relates to a multi-station charging pile. Background Art

[0002] Charging piles are generally built in conjunction with parking spaces in parking lots (garages). There are two types of charging methods for electric vehicles: fast charging and slow charging. Fast charging and slow charging are relative concepts. Generally, fast charging is high-power DC charging, which can fully charge 80% of the battery capacity in half an hour. Slow charging refers to AC charging, and the charging process takes 6 to 8 hours. The speed of electric vehicle charging is closely related to the power of the charger, the battery charging characteristics and temperature. Under the current level of battery technology, even fast charging takes 30 minutes to charge to 80% of the battery capacity. After exceeding 80%, in order to protect the safety of the battery, the charging current must be reduced, and it will take longer to charge to 100%. With the promotion of more and more electric vehicles, the charging site required is getting larger and larger, which cannot meet the charging needs of electric vehicles.

[0003] In existing multi-station charging piles, the charging guns used for charging are mostly exposed to the outside, which is not convenient for storage. When encountering strong convective weather such as strong winds and heavy rains, the exposed interfaces of the charging guns are prone to rainwater infiltration, affecting the subsequent overall practicality of the charging pile. Therefore, a multi-station charging pile is needed to help solve this problem. Utility Model Content
