Embodiment Construction

[0026] The operation of public transport vehicles has the characteristics of more operations during the day, fewer operations at night, and less operation in the early morning. Moreover, after the first bus in the morning, it presents the characteristics of a sequential factory area. In addition, the industrial electricity prices in many areas vary according to the time of day, but generally the rates in the middle of the night are much lower than those in normal work during the day. Taking advantage of these characteristics, this patent provides a method for dynamically distributing the charging power of pure electric vehicles with new energy sources for public transportation, so that new energy electric vehicles can fully utilize the valley electricity price at night, and complete the charging of the battery with a small charging rate. To achieve battery charging in a more efficient and longer life charging method.

Abstract

The invention discloses a public transportation new energy pure trolley bus charging power dynamic allocation method, and comprises a vehicle-mounted battery detection device and a charging power dynamic allocation system. The method comprises the steps of detecting the real-time electric quantity Q of a battery by installing the vehicle-mounted battery detection device, and meanwhile, detecting the performance parameter set C when the battery works; transmitting the electric quantity Q and the performance parameter set C to the charging power dynamic allocation system in real time; detecting and recording the output power of all charging piles by means of the charging power dynamic allocation system, and sorting the different output power of all charging piles from big to small. Combined with a public transportation schedule dispatching system, the method provides multiple charging strategies and improves the power load and the utilization efficiency of charging facilities; when a bus is charged in the night, primary and secondary charging operation can be conducted combined with the position number of the public transport vehicles, and the system can set the charging power and the charging time according to the actual condition, and preferentially and quickly charges the started public transport vehicles in the morning, meets the work requirements of the main public transport vehicles, and improves the working efficiency of a charging station.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of charging intelligent management of electric vehicles with new energy sources, and in particular relates to a method for dynamically distributing charging power of electric vehicles with new energy sources for public transportation. [0003] Background technique: [0004] The existing charging technology supports two charging modes: wheel charging and average power distribution for the vehicle. It cannot automatically allocate power according to the working needs of the vehicle, and has poor awareness of battery protection. [0005] After the vehicle is fully charged, the charging power cannot be allocated to other vehicles, and the utilization rate of the equipment is low. [0006] The existing charging technology can only realize the plug-and-play charging of the vehicle, and it is impossible to reserve the charging time. For example, when charging the vehicle with low-peak power, manual intervent...
