摘 要：双源电动汽车采用动力电池系统和受电弓充电系统两种电源，为防止由于电池过充或过放而导致电池出现性能和寿命衰减过快问题，需要合理控制受电弓充电系统中的车载隔离DC/DC输出功率。对此，本文提出一种基于动力电池SOC的受电弓充电功率控制策略，并予以验证。

Abstract: Dual-source electric vehicles use a power battery system and a pantograph charging system as two power supplies.To prevent the rapid decline of performance and life of the battery due to overcharge or overdischarge,it is necessary to reasonably control the on-board isolated DC/DC output power of the panto-graph charging system.This paper proposes and verifies a pantograph charging power control strategy based on power battery SOC.
Key words: dual-source electric vehicle; pantograph; vehicle isolation DC/DC; battery SOC
