本发明涉及电动汽车换电领域，尤其涉及一种充电和储能一体式换电站。The invention relates to the field of electric vehicle power exchange, in particular to a charging and energy storage integrated power exchange station.
背景技术Background technique
电动汽车(BEV)是指以车载电源为动力，用电机驱动车轮行驶的车辆。由于具有结构简单、节能环保、噪音小等优点，电动汽车的市场普及率越来越高。随着电动汽车的推广，如何为电动汽车进行及时充电称为制约其发展的重要因素。Electric vehicle (BEV) refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Due to the advantages of simple structure, energy saving and environmental protection, and low noise, the market penetration rate of electric vehicles is getting higher and higher. With the promotion of electric vehicles, how to charge electric vehicles in time is an important factor restricting their development.
现有技术中通常采用动力电池充电或动力电池换电的方式实现对电动汽车运行里程的延续。动力电池充电方式是指利用充电桩对电动汽车的动力电池进行充电，这种方式通常需要较长的时间，容易造成充电车辆排队拥挤，严重影响了用户体验。动力电池换电方式是指直接用充满电的动力电池更换电力耗尽的动力电池，然而，随着电动汽车的电池比能量(即单位重量或单位体积的电池所产生的能量)的不断提升，现有的充电机功率很难满足在数分钟(例如3至5分钟)内换电频次的需求，尤其是在换电高峰期，电网能承受的负荷接近满负荷，此时很难提供较大的充电电流给电力耗尽的电池充电，因此，严重影响了换电站的换电频次，导致电动汽车用户排队严重；若提前准备更多的备份电池，则会增加换电站的运营成本，另外，当换电站的体积有限制时，备份电池的数量也会受到限制。In the prior art, the continuation of the running range of the electric vehicle is usually realized by charging the power battery or exchanging the power of the power battery. The power battery charging method refers to the use of charging piles to charge the power battery of an electric vehicle. This method usually takes a long time, and it is easy to cause crowded queues of charging vehicles, which seriously affects the user experience. The power battery replacement method refers to directly replacing the exhausted power battery with a fully charged power battery. However, with the continuous improvement of the battery specific energy of electric vehicles (that is, the energy generated by the battery per unit weight or unit volume), The power of the existing chargers is difficult to meet the demand for the frequency of power exchange within a few minutes (such as 3 to 5 minutes). Therefore, the frequency of battery swapping at the swapping station is seriously affected, resulting in serious queues for electric vehicle users; if more backup batteries are prepared in advance, the operating cost of the swapping station will increase. In addition, When the size of the swap station is limited, the number of backup batteries will also be limited.
如何提供一种在降低换电站运营成本的前提下提高换电频次的换电站是目前亟待解决的问题。How to provide a power exchange station that can increase the frequency of power exchange on the premise of reducing the operating cost of the power exchange station is an urgent problem to be solved at present.

需要说明的是，上述三种具体实施方式只是示例性的介绍各个隔离开关、选通开关以及机动变压模块相互配合的方式。其中，各个隔离开关以及各个选通开关的开合可以根据具体需求来进行设置，变压模块、电池仓、直流调整模块、储能电池的数量也可以根据具体地应用场景进行增加或减少，例如：还可以将变压模块设置为16个(其中可以包括10个标准变压模块和6个机动变压模块)，还可以将直流调整模块设置为8个，还可以将每一个储能电池设置为由4个储能子电池并联组成，本实施例对此都不作限制。It should be noted that the above-mentioned three specific implementation manners are only illustrative of the ways in which the isolation switches, the gating switches and the motorized transformer modules cooperate with each other. Among them, the opening and closing of each isolation switch and each gate switch can be set according to specific needs, and the number of transformer modules, battery compartments, DC adjustment modules, and energy storage batteries can also be increased or decreased according to specific application scenarios, such as : The number of transformer modules can also be set to 16 (including 10 standard transformer modules and 6 motorized transformer modules), the number of DC adjustment modules can also be set to 8, and each energy storage battery can be set to Since it is composed of four energy storage sub-batteries in parallel, this embodiment does not limit this.
本实施例的技术方案通过设置标准变压模块以及机动变压模块，可以便捷地调整提供给直流母线的电力功率，从而可以实现对待充电车辆的柔性充电，并且可以根据需要灵活调整各个模块的数量和组合方式，有效提高了换电站设计的灵活性。The technical solution of this embodiment can easily adjust the electric power provided to the DC bus by setting the standard transformer module and the motor transformer module, so that flexible charging of the vehicle to be charged can be realized, and the number of each module can be flexibly adjusted as required And the combination method effectively improves the flexibility of the design of the power exchange station.
