Description

Charging system and method for managing one or more charging groups

technical field

The present invention relates to new energy vehicle technology, and in particular, to a charging system and a method for managing one or more charging groups.

Background technique

In order to greatly reduce the carbon dioxide emissions of automobiles, the automobile industry is investing a lot of manpower and material resources to develop new types of vehicles that use electricity as a power source, such as hybrid vehicles and pure electric vehicles. A pure electric vehicle refers to a vehicle that uses an on-board battery as a power source and uses a motor to drive the wheels and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic.

However, there are still many difficulties in the popularization and promotion of the pure electric vehicle market. For example, the energy supplement of the power battery is a relatively prominent problem. Specifically, in new vehicles, batteries are used to store electrical energy. Considering safety, cost, and service life, the battery energy density of currently developed electric vehicles is not high, which limits their range after each charge. .

On the other hand, the idle rate of charging facilities remains high, resulting in high operating costs for charging. In addition, many commercial parking lots still have charging pile parking spaces occupied by fuel vehicles, which further deteriorates the idle rate of charging facilities. In addition, many commercial places will also have insufficient power capacity as the demand for charging increases.
