Description

Device and method suitable for remotely controlling charging process

The present invention relates to the field of power applications, and in particular to an apparatus and method suitable for remotely controlling a charging process. Background technique

At present, the greenhouse effect hazard has increased year by year and the shortage of oil has become more and more serious. Traditional cars have further aggravated the increasingly serious environmental pollution and energy shortage. Electric vehicles are highly efficient and have low emissions, which can fundamentally reduce dependence on oil, increase the use of renewable energy, and reduce emissions of carbon dioxide and pollutants. Countries all over the world have made huge amounts of money to carry out electric vehicle technology, especially in the core power supply system and drive system, and have made a lot of research and made great progress.

An electric vehicle is a vehicle that is driven by a motor in whole or in part. At present, there are mainly pure electric vehicles, hybrid vehicles, fuel cell electric vehicles, and external plug-in hybrid vehicles. In order to supply electric power to electric vehicles, a charging device capable of charging an electric vehicle must be provided. At present, electric vehicle charging equipment mainly includes charging piles, charging stations, and the like.

Generally speaking, the charging pile is relatively simple, has a small footprint, is easy to install, can be installed in an electric vehicle charging station, a public parking lot, and is easy to operate, and is an important electric vehicle charging facility. Similar to the car filling station, the charging station is a larger type of "power station" that can quickly charge mobile phones, electric vehicles, electric vehicles and other equipment. It can charge several sets to dozens of battery packs at the same time. High-power off-board chargers quickly charge the battery directly, or you can use a non-vehicle or on-board charger to slowly charge the battery.

In the power system, the electrical load is usually changed with time. It is usually divided into three stages: peak, flat and trough, or more time or two. Due to the large amount of electricity used during the peak period, it is prone to overload, which is not conducive to the safe operation of the equipment. The electricity consumption in the valley period is much lower than that in the peak period and the peaceful period. This results in a low grid load rate, which is also not conducive to the normal operation of the equipment. Row. The electricity consumption during the period is between the peak period and the valley period. The lowest valley is the minimum load setting moment in which the electricity consumption in the valley period is relatively small, and is the lowest time at which the grid load rate is low. In order to make full use of the non-peak period, especially the electricity in the valley and the lowest valley, many electrical equipment will adjust the electricity consumption time to the non-peak period (especially the valley period and the lowest valley) to make full use of electric energy and reduce the grid. The difference in electricity demand between peak and non-peak periods.

However, the charging device of the prior art does not provide the function of remote control. When the user wishes to change the charging mode and charging parameters of the charging device for charging the vehicle, the setting can only be made again on the charging device. In particular, when the user has moved away from the charging device, the above-described change of the charging mode and the charging parameters become very inconvenient.
