Description

This creation is about a time-sharing charging control system and equipment for electric vehicles, especially a system and equipment that controls the power supply port to supply power to the electric vehicle or stop the power supply.

With the rising awareness of environmental protection, multi-national policies announced the prohibition or restriction of fuel vehicles, making electric vehicles gradually move towards the mainstream. In the future, the market demand for electric vehicles will increase day by day. The Chinese government also uses laws and regulations to encourage residential buildings and shopping malls to install charging parking spaces. Therefore, the demand for power supply ports for electric vehicles will also increase.

For example, existing parking lots have to be equipped with charging piles. After users park their electric vehicles in parking spaces with charging piles, they must connect the electric vehicles to the charging piles to charge the electric vehicles. However, when the parking spaces are equipped with charging piles When occupied by a fuel vehicle, the charging pile will be idle and cannot be used to charge electric vehicles. If all parking spaces in the parking lot have to be charged for electric vehicles, the parking lot must not only be installed in each parking space. Charging piles, and need to apply to the power company to set up enough power load to provide enough total power supply, otherwise it may cause a large number of electric vehicles to be charged at the same time, resulting in overload and power failure.

In addition, because electric vehicles and other electric vehicles are not yet fully popularized, there are also cases where the utilization rate of charging piles is low. For example, in the parking lots of collective residential buildings, most of them are concentrated during off-get off work hours, while commercial buildings are mostly concentrated on weekdays and department stores. During hot business periods such as weekends and holidays, charging piles are mostly idle during the rest of the time, and the average power usage efficiency is low. Therefore, under the existing technology, if it is necessary to add charging piles, and at the same time, it is necessary to apply to the power company to set up additional electric loads, but in fact, if there are only a few periods of time when there is a demand for charging a large number of electric vehicles, the efficiency of the use of power supply is not high. , So that the benefit of increasing the electrical load or adding charging piles is still low.

The purpose of this creation is to provide a time-sharing charging control system and equipment for electric vehicles, which can charge electric vehicles more efficiently by using existing household sockets when the power supply is limited. It also meets the requirements of widely setting up charging stations.

An electric vehicle can increase the endurance by 160 kilometers after charging for 4 hours, which should ensure normal use the next day. Taking a parking lot with 60 parking spaces as an example, assuming that the penetration rate of electric vehicles in the future is 30%, there are about 18 electric vehicles in the parking lot that have a daily charging demand (60*30%=18). If charging piles are installed, the parking lot needs to apply to the power company for 126 kW of electricity (7*18=126) to meet the charging needs of the 18 electric vehicles. If according to the control system created by this author, the timing module can set a continuous charging period, that is, the basic charging period is 4 hours, then the daily charge can be divided into about 3 charging steps (12/4=3), then the parking lot can be set The maximum number of electric vehicles that can be charged at the same time in each stairway is 6 (18/3=6). If each electric vehicle is charged with 7 kW of electricity, the parking lot needs to have 42 kW of electricity (7* 6=42) The load can meet the charging demand of the 18 electric vehicles, and there is no need to apply for additional power from the power company.

Furthermore, according to the control system and control equipment provided by this creation, it is possible to obtain information about each power port 3 powering or stopping the power supply of electric vehicles, and further adjust the set basic charging period or extend the charging period to optimize the charging efficiency For example, when the penetration rate of electric vehicles reaches 40%, a parking lot with 60 parking spaces, and there are about 24 electric vehicles parked every day (60*40%=24), set the basic charging period If it is 3 hours, it can be divided into about 4 charging steps per day (12/3=4), and each time 6 electric vehicles can be charged with 7 kW of electricity, the total power supply will not change (42 kW). Under the circumstance, it can still meet the charging demand of about 24 electric vehicles.

Based on the above, it can be understood that the embodiment of this creation has the following beneficial effects: 1. By setting the maximum number of electric vehicles that are charged at the same time and the basic charging period, time-sharing charging can be performed under the existing power supply load. , And effective use of power supply, so as to prevent a single electric vehicle from occupying and charging for a long time, which is conducive to more electric vehicles to use and charge; 2.
