All-in-one high-voltage power supply distribution assembly for non-road wide-body vehicle and working method

Abstract

The invention particularly relates to an all-in-one high-voltage power supply distribution assembly for a non-road wide-body vehicle and a working method. The all-in-one high-voltage power supply distribution assembly for the non-road wide-body vehicle comprises a high-voltage power supply module, a high-voltage control module and a first low-voltage connector; when a CAN bus between the high-voltage control module and the vehicle control unit fails, enabling control is carried out between the high-voltage control module and the vehicle control unit through a hard wire; the high-voltage control module receives a driving signal of the vehicle control unit and drives the high-voltage power supply module to execute a corresponding instruction; the high-voltage control module collects the working state of the high-voltage power supply module and sends the working state to the vehicle control unit; the CAN bus and the hard wire are arranged between the high-voltage control module and the whole vehicle controller, redundancy control can be conducted on the DC / DC converter, the air pump DC / AC converter and the oil pump DC / AC converter in the high-voltage power module, the continuous working capacity of the high-voltage power module is greatly improved, and the vehicle steering and braking capacity is guaranteed.

Description

Technical field [0001] The present invention belongs to the high voltage power distribution assembly technologies, and particularly relates to a non-road vehicle-one wide-body high-voltage power distribution assemblies and methods of work. Background technique [0002] Conventional wide-body-road vehicle with multi-shot high-voltage power distribution assembly, generally integrated DC / DC, pumps, pump DC / AC, electric drive core module; a plurality of CAN bus and vehicle VCU, BMS communication , multi-internal controller receives the VCU, BMS CAN bus message information control the pump DC / AC, pump DC / AC, DC / DC. [0003] New energy vehicles due to the presence of relatively conventional car drivers more serious electromagnetic interference exists motor controller, CAN bus susceptible to electromagnetic interference. [0004] When the multi-card and VCU, BMS bus where a bus fault or disturbance occurs, the target device-one internal pump DC / AC, pump DC / AC, DC / DC not ...

AI Technical Summary

Problems solved by technology

[0005] The existing all-in-one high-voltage power distribution assembly for non-road wide-body vehicles has no range extender input interface except for the power battery input interface, and is not suitable for range-extended hybrid power systems.
