Description

一种车载充电机以及车载充电系统Vehicle charger and vehicle charging system 技术领域Technical field
本发明涉及汽车电子领域，具体涉及了一种车载充电机以及车载充电系统。The present invention relates to the field of automotive electronics, and in particular to an in-vehicle charger and an in-vehicle charging system.
背景技术Background technique
目前，新能源汽车已日趋成为未来汽车工业的发展方向，新能源汽车经过了十多年的全球化发展，人们逐步对纯电动汽车的电能供给方式达成了共识：主流的方式是“谷电充电”，在深夜八个小时的“谷电”期间，要求在6-8个小时的慢速充电时间之内为纯电动汽车充满电。At present, new energy vehicles have become the development direction of the future automobile industry. After more than a decade of global development of new energy vehicles, people have gradually reached a consensus on the power supply mode of pure electric vehicles: the mainstream way is “valley charging”. During the eight hours of "Valley" in the middle of the night, it is required to fully charge the pure electric vehicle within 6-8 hours of slow charging time.
现有技术中，车载充电机大多采用单相220V输入，单相交流充电桩的最大输出电流为32A，所以车载充电机的输出功率等级为3.3KW或者6.6KW，目前，6米中巴车采用了车载充电机技术，但是其中一些中巴车的续航里程达到了200多公里，如果给这些电动中巴车电池充满电，可以装70-80度电，当采用6.6KW的单相车载充电机时，充电时间将会达到10-12小时左右，无法满足客户要求的7-8小时充满电的要求，因此，减少充电时间成为了亟待解决的问题。In the prior art, most of the on-board chargers use single-phase 220V input, and the maximum output current of the single-phase AC charging pile is 32A, so the output power level of the on-board charger is 3.3KW or 6.6KW. Currently, the 6-meter bus is adopted. The car charger technology, but some of the CMB's cruising range has reached more than 200 kilometers, if these electric bus batteries are fully charged, you can install 70-80 degrees of electricity, when using 6.6KW single-phase car charger At the time, the charging time will reach 10-12 hours, which can not meet the customer's requirement of 7-8 hours of full charge. Therefore, reducing the charging time has become an urgent problem to be solved.
发明内容Summary of the invention
本发明实施例公开了一种车载充电机以及车载充电系统，可以使车载充电机兼容单相与三相功率输入，满足不同场合的交流输入条件，解决了兼容不同类型交流充电桩的需求。The embodiment of the invention discloses an on-board charger and an on-board charging system, which can make the on-board charger compatible with single-phase and three-phase power input, meet the AC input conditions of different occasions, and solve the requirement of being compatible with different types of AC charging piles.
