technical field

The invention relates to the field of electric power applications, and in particular to a device and method for timing charging.

Background technique

At present, the harm of the greenhouse effect is increasing year by year and the problem of oil shortage is becoming more and more serious. Traditional automobiles further aggravate the increasingly serious environmental pollution and energy shortage problems. Electric vehicles have high efficiency and low emissions, which can fundamentally reduce dependence on oil, increase the use of renewable energy, and reduce emissions of carbon dioxide and pollutants, and have received widespread attention. Countries all over the world have invested huge sums of money in the research and development of electric vehicle technology, especially in the core power supply system and drive system. A lot of research has been done and great progress has been made.

Electric vehicles refer to vehicles that are driven entirely or partially by motors. At present, there are mainly pure electric vehicles, hybrid vehicles, fuel cell electric vehicles, and external rechargeable hybrid vehicles. In order to supply electric power to an electric vehicle, it is necessary to install a charging device capable of charging the electric vehicle. At present, electric vehicle charging equipment mainly includes charging piles and charging stations.

Generally speaking, charging piles are relatively simple, occupy a small area, and are easy to install. They can be installed in electric vehicle charging stations and public parking places, and are easy to operate. They are important electric vehicle charging facilities. The charging station is similar to the car gas station. It is a relatively large "recharging station". It can quickly charge mobile phones, electric vehicles, electric vehicles and other equipment. It can charge several to dozens of battery combinations at the same time. It can be used The high-power off-board charger directly charges the battery quickly, and the off-board or on-board charger can also be used to slowly charge the battery.

In the power system, the power load usually changes with time, and is usually divided into three stages of peak, flat and low periods every day, and there can also be more periods or two periods. Due to the large power consumption during the peak period, it is prone to overload, which is not conducive to the safe operation of the equipment. The power consumption in the valley period is much lower than the power consumption in the peak period and the normal period, which leads to a low load rate of the power grid, which is also not conducive to the normal operation of the equipment. Among them, the average power consumption is between the peak period and the valley period. The lowest valley is a period of time when electricity consumption is relatively small in the valley period, and it is a period of time when the load rate of the grid is low and the lowest.

At present, in order to make full use of the off-peak period, especially the valley period and the lowest valley, many electrical equipment adjust the power consumption time to the off-peak period (especially the valley period and the lowest valley), so as to make full use of electric energy, and can reduce The difference in electricity demand on the grid between peak and off-peak periods. However, the charging equipment in the prior art does not provide an appropriate timing charging function, and it is impossible to conveniently use the set time, the set delay time and the fixed time to end the charging mode to charge the electric vehicle.

In order to solve this problem, it is necessary to provide a device and method capable of charging an electric vehicle by using a set time, a set delay time, and a fixed time to end the charging mode.
