Abstract

The invention discloses a split type DC intelligent charging pile for electric automobiles. According to the split type DC intelligent charging pile for electric automobiles, the effective distribution of chargers can be realized through controlling an intelligent output controller according to different loads, the circuit is simple and the charging combination manner is flexible and diversified. The split type DC intelligent charging pile for electric automobiles is characterized in that a billing control unit is used for selecting to output the quantity of the chargers through carrying out data interaction with the intelligent output controller according to a BMS charging requirement; the chargers can be freely switched in and out; and by adopting a control manner of enabling the chargers with less charging work time or less output power to be prior to realize the prior application of the chargers, the frequently busy / frequently free state of the chargers is avoided and the utilization rate of the chargers is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, selects the number of output chargers through an intelligent output controller, and realizes free switching between each charger. This smart charging system is suitable for all-in-one multi-gun output. Background technique [0002] Electric vehicle is a clean, efficient and sustainable means of transportation, and it is an electric-driven road vehicle. From an environmental perspective, the use of electric vehicles in urban transport can achieve zero or very low emissions. Batteries are the power source of electric vehicles, and they are also the key factor that has always restricted the development of electric vehicles. Now, the technology of zero-emission electric vehicles has gradually matured, and one charging trip can basically meet the needs of urban traffic. The main problems of large-scale application are high initial cost and unsatisfactory driving range. By developing a fast...
