Abstract

The invention discloses a powertrain submodule assembly based on modularization. The powertrain submodule assembly comprises a radiator, power devices, alternating-current board cards, direct-currentboard cards and a control board card. The power devices are installed on the two sides of the radiator respectively, the alternating-current board cards and the direct-current board cards are sequentially connected to the two sides of the power devices, the control board card is installed on the outer side of one of the direct-current board cards, and the power devices, the alternating-current board cards, the direct-current board cards and the control board card are fixed to the two sides of the radiator through structural parts; and first alternating-current ports and second alternating-current ports are led out of the alternating-current board cards, and positive electrode ports, negative electrode ports, first fault signal ports and first driving signal ports are led out of the direct-current board cards. Due to the design of the submodule modular structure, the installation mode in a vehicle is more flexible, the production and maintenance cost of the power system of the electricvehicle is greatly reduced, and the utilization rate and cruising ability of the space in the vehicle can be effectively improved.

Description

technical field [0001] The invention relates to a modular-based power assembly sub-module assembly, which belongs to the technical field of new energy sources. Background technique [0002] In recent years, with the vigorous development of the new energy electric vehicle industry, on-board electronic equipment has shown a trend of miniaturization, integration, and high power density. However, the BMS, motor drive unit, DC / DC unit, PDU unit and OBC charging unit in the pure electric vehicle powertrain system industry are mostly designed separately and installed in the vehicle through structural combination, resulting in powertrain The system has low energy density, complex control, difficult installation and maintenance, low system reliability and high cost, and is not suitable for the development trend of modularization, integration, integration, platformization, light weight, and intelligence of the whole vehicle. Contents of the invention [0003] The purpose of the pre...
