The invention relates to a battery connector. The battery connector (1) comprises a voltage transformation and stabilization unit (2), a coupling unit (3) and a contactor (4), the contactor (4) is connected to the output end of a power battery (101) through the voltage transformation and stabilization unit (2), and the contactor (4) receives a control signal sent by a battery management system (102) through the coupling unit (3). The invention also relates to a vehicle battery system (10) comprising a power battery (101), a battery management system (102) and a battery connector (1) according to the invention. According to the invention, the contactor can obtain stable driving voltage from the high-voltage output end of the power battery, so that the robustness of the contactor is enhanced, the influence of impact current generated by closing of the contactor on the battery management system is avoided, the operation stability of the battery management system is enhanced, and the service life of the battery management system is prolonged. And the electromagnetic compatibility of the vehicle power system is improved.
本发明涉及一种电池连接器。所述电池连接器(1)包括变压稳压单元(2)、耦合单元(3)和接触器(4),其中,接触器(4)经由所述变压稳压单元(2)连接至动力电池(101)的输出端,且接触器(4)经由所述耦合单元(3)接收由电池管理系统(102)发出的控制信号。本发明还涉及一种车辆电池系统(10),其包括动力电池(101)、电池管理系统(102)和根据本发明的电池连接器(1)。根据本发明,接触器可以从动力电池的高压输出端获取稳定的的驱动电压,由此增强接触器的鲁棒性,同时避免了接触器闭合产生的冲击电流对电池管理系统的影响,增强了电池管理系统的运行稳定性,且改善了车辆动力系统的电磁兼容性。
