The invention discloses a vehicle-mounted power supply conversion and distribution unit integrated device. A vehicle-mounted power supply comprises a vehicle-mounted charger, a DC/DC converter and a PDU module. Circuits of the vehicle-mounted charger, the DC/DC converter and the PDU module are all arranged in the vehicle-mounted power supply conversion and distribution unit integrated device to form a power supply circuit module. By the adoption of the technical scheme, the vehicle-mounted charger, the DC/DC converter and the high-voltage junction box assembly are integrally designed, a powercircuit, a shell and the like are shared, the power conversion and distribution requirements of the whole vehicle are met, and the purposes of reducing the size, being high in power density and reliability, optimizing the arrangement space of the whole vehicle and the like are achieved; the wire harness is effectively and tightly connected with other related parts of the whole vehicle, so the wireharness distribution is greatly optimized, the arrangement space requirement of the whole vehicle is reduced, the adapter connectors are saved, the cable loss is reduced, the production and assemblyprocedures are simplified, and the product percent of pass is improved; the cost is reduced, the safety and effectiveness are achieved, and the reliability is high.

    本发明公开了一种车载电源转换与分配单元集成装置,所述的车载电源包括车载充电器、DC/DC变换器和PDU模块;所述的车载充电器、DC/DC变换器和PDU模块的电路均设置在车载电源转换与分配单元集成装置内,形成电源电路模块。采用上述技术方案,对车载充电器、DC/DC变换器和高压接线盒总成进行集成化设计,共用功率电路、壳体等,满足整车电源转换与分配需求,实现体积减小、功率密度大、可靠性较高、整车布置空间优化等目的;与整车其他关联零部件有效、紧密连接,极大的优化线束分布,缩减整车布置空间需求,节省转接插件和减少线缆损耗、简化生产、装配工序,提高产品合格率;成本降低、安全有效、可靠性高。
