The invention relates to the technical field of electronic information, and particularly relates to a railway vehicle power battery system charging loop which comprises two clusters of battery boxes. A charging loop electrical system is arranged in the two clusters of battery boxes, and a battery management system is arranged on the charging loop electrical system. The charging loop electrical system is provided with a safety interlocking protection circuit for two-way direct current charging interfaces on the two sides of the two clusters of battery boxes. A high-voltage box is included and is mounted on the two clusters of battery boxes so that high-voltage and low-voltage automatic control of charging is realized; and a display screen controller is included too. The purpose of improving the charging safety of the power battery is achieved, the safety interlocking protection circuit is matched, charging safety can be ensured, single-side charging on any side is supported, simultaneous charging on the left side and the right side is not supported, the risk that relay contacts are adhered when a relay is abnormally cut off in a large-current state can be avoided, and meanwhile, the charging heating loop meets the low-temperature large-current direct-current charging requirement.
本发明涉及电子信息技术领域,尤其涉及一种轨道车辆动力电池系统充电回路,包括:两簇电池箱,所述两簇电池箱的内部设有充电回路电气系统,所述充电回路电气系统上设有电池管理系统,所述充电回路电气系统上设有供两簇电池箱两侧双路直流充电接口的安全互锁保护电路;高压箱,所述高压箱安装在两簇电池箱上,实现充电的高低压自动控制;显示屏控制器。本发明达到了提高动力电池充电安全性的目的,配合安全互锁保护电路能够确保充电安全,支持任何一侧的单侧充电,不支持左右两侧同时充电,而且在大电流状态下,能够异常切断继电器时存在继电器触点粘连的风险,同时充电加热回路适应低温大电流直流充电要求。
