Embodiment
[0022] An integrated device of a hybrid vehicle power battery and a high-voltage distribution box involved in this embodiment, such as Figure 1 to Figure 6 As shown, the device includes an external box, a power battery, a high-voltage power distribution unit (PDU), electrical connectors, and various sensors. The design of the entire device adopts a modular design, and the battery module can be directly replaced during maintenance, reducing project maintenance links , no maintenance on the battery module. Reasonably arrange the positions of components, reduce connectors and fixing parts, make maintenance operations such as detection and module replacement simple and convenient, and achieve less disassembly and less movement when replacing battery modules and other parts, reducing the technical level requirements for maintenance personnel and workload. The cells and all devices are selected for normal storage and operation under temperature variations within the specified envi...

The invention discloses an integrated device of a hybrid vehicle power battery and a high-voltage distribution box. The integrated device comprises an external box body, the power battery, a high-voltage distribution box PDU and an electrical connector; the power battery and the high-voltage distribution box PDU are installed in the external box body and are internally connected through a wire harness. The power battery is composed of a battery box body, a ternary lithium battery pack and a battery management system (BMS). An electrical connector which is used for connecting the internal powerbattery and the high-voltage distribution box to other electric equipment is installed on the external box body. The problems that an existing hybrid vehicle is large in total system mass, difficultin overall space arrangement and difficult to install are solved.
Description
technical field [0001] The invention relates to the field of hybrid vehicle power systems and power distribution systems, in particular to an integrated device of a hybrid vehicle power battery and a high-voltage distribution box. Background technique [0002] With the increasing development of the new energy vehicle industry, more and more new energy vehicle technologies have been developed rapidly, and the overall structure different from transmission fuel vehicles has also stimulated a large number of emerging new energy vehicle technologies. Compared with the core position of the engine of traditional fuel vehicles, the technical focus of new energy vehicles is the three-electric system represented by the power battery center. [0003] At present, in order to improve vehicle performance, all hybrid vehicles, especially special vehicles, face the problems of excessive overall system mass, difficult overall space layout, and difficult installation.
