背景技术Background technique
本发明涉及到电动汽车交直流组合充电设备的充电流程控制方式，充电设备可同时提供交流和直流的充电服务，保障电动汽车可靠、灵活接入电网。采用交直流组合充电可以提高充电的灵活性，提高充电车位的使用效率，减少充电站的土地建设面积，从而节约土地，减少基础建设成本。电动汽车交直流组合充电是改善用户充电体验的重要组成部分，为充电设备根据电网和电动汽车的需要合理优化提供平台。The invention relates to a charging process control method of an AC-DC combined charging device for an electric vehicle. The charging device can provide charging services for both AC and DC at the same time, ensuring that the electric vehicle is reliably and flexibly connected to a power grid. The use of AC and DC combined charging can improve the flexibility of charging, improve the efficiency of charging parking spaces, and reduce the land construction area of charging stations, thereby saving land and reducing infrastructure costs. The combined AC and DC charging of electric vehicles is an important part of improving the charging experience of users, and provides a platform for charging equipment to be rationally optimized according to the needs of the grid and electric vehicles.
目前电动汽车的充电模式有两种，一种为交流充电模式，另一种为直流充电模式。交流充电存在充电时间长、充电设备使用率低的问题，直流充电可大大提高充电效率，但大电流充电对电池的寿命存在一定的影响。At present, there are two charging modes for electric vehicles, one is AC charging mode and the other is DC charging mode. AC charging has the problems of long charging time and low usage rate of charging equipment. DC charging can greatly improve charging efficiency, but high current charging has a certain impact on battery life.
针对以上问题，国内外诸多车企提出在电动汽车上同时设计直流和交流充电接口，以直流充电加快充电速度，缩短充电时间，提高充电设施的使用效率；以交流充电满足用户长时间停车慢充的需求。考虑若在电动汽车上同时安装交流和直流接口，必然造成成本的增高，用户使用的便利性也大大降低，因此，宜将交、直流充电接口组合成一体，并将交流充电功能和直流充电功能融合于同一充电设备。In response to the above problems, many car companies at home and abroad have proposed to design DC and AC charging interfaces on electric vehicles at the same time, using DC charging to speed up the charging speed, shorten the charging time, and improve the efficiency of charging facilities; use AC charging to meet users' long-term parking and slow charging. demand. Considering that if the AC and DC interfaces are installed on the electric vehicle at the same time, it will inevitably increase the cost and greatly reduce the convenience of users. Therefore, it is advisable to combine the AC and DC charging interfaces into one, and combine the AC and DC charging functions. Integrate into the same charging device.
针对此情况，IEC成立了专门的工作组以制定统一（或通用）的接口标准—组合（COMBO）型接口。在参考现有的几种直流和交流充电接口的基础上，提出了一种既能实现交流充电又能进行直流充电的接口。近期，欧洲汽车工业协会向欧委会提交了一份电动汽车充电接口标准化建议书，提出了COMBOType2接口，充电接口在欧盟成员国内得到了统一。In response to this situation, IEC has set up a special working group to develop a unified (or general) interface standard - combination (COMBO) type interface. On the basis of referring to several existing DC and AC charging interfaces, an interface that can realize both AC charging and DC charging is proposed. Recently, the European Automobile Manufacturers Association submitted a proposal to the European Commission for the standardization of the charging interface of electric vehicles, proposing the COMBO Type 2 interface, and the charging interface has been unified in EU member states.
电动汽车交直流组合充电控制方式作为电动汽车充电技术研究的一个重要组成部分，对实现了电动汽车BMS与电动汽车交直流组合充电设备之间实时信息交换，优化能源供应的同时提高车辆充电的效率和降低车辆充电的成本，以及根据电动汽车用户需求提供更加合理、舒适的充电操作有着重要的意义。As an important part of the electric vehicle charging technology research, the electric vehicle AC-DC combined charging control method realizes the real-time information exchange between the electric vehicle BMS and the electric vehicle AC-DC combined charging equipment, optimizes energy supply and improves the efficiency of vehicle charging It is of great significance to reduce the cost of vehicle charging and provide a more reasonable and comfortable charging operation according to the needs of electric vehicle users.
