Low-voltage power distribution box for pure electric bus

Abstract

The invention discloses a low-voltage distribution box for a pure electric bus. The low-voltage distribution box is characterized by being arranged in an engine cabin of the pure electric bus, and comprising a shell, an electromagnetic power main switch assembly arranged in the shell, a plurality of relays inserted in the shell in a pluggable mode through a relay insertion groove set, a low-voltage distribution CAN control module, a battery, a first fuse insertion groove set, a second fuse insertion groove set, a first fuse assembly inserted in the first fuse insertion groove set in a pluggable mode, a second fuse assembly inserted in the second fuse insertion groove set in a pluggable mode, a 100 A fuse R0, a 150 A fuse R1, a front CAN control power fuse R2, a top CAN control power fuse R3, a rear CAN control power fuse R4 and a low-voltage distribution CAN control power fuse R5; an L-shaped installation plate is installed on the left side of the shell and is higher than the bottom wall of the shell, and the low-voltage distribution CAN control module is installed in the parallel space of the L-shaped installation plate and the bottom wall of the shell.

Description

technical field [0001] The invention relates to a low-voltage power distribution box of a pure electric passenger car. Background technique [0002] With the development of commercial vehicle technology, the safety and reliability requirements of electrical systems are getting higher and higher. The electrical components in the traditional engine and the VCU of the electric bus are directly connected by a wire harness. Each electrical component is connected to the VCU through a wire harness, which results in a large number of wire harnesses, which are very large and take up a lot of space. When an electrical component When the wiring harness fails, it is difficult to eliminate and repair. Moreover, the traditional low-voltage power distribution box can only realize the simple control of the power on and off of the electrical components in the electric vehicle, and cannot monitor the status of each electrical component in real time. Users cannot immediately understand the st...

Problems solved by technology

The electrical components in the traditional engine and the VCU of the electric bus are directly connected by a wire harness. Each electrical component is connected to the VCU through a wire harness, which results in a large number of wire harnesses, which are very large and take up a lot of space. When an electrical component When the wiring harness fails, it is difficult to eliminate and repair

Moreover, the traditional low-voltage power distribution box can only realize the simple control of the power on and off of the electrical components in the electric vehicle, and cannot monitor the status of each electrical component in real time. Users cannot immediately understand the status and faults of electrical components, and cannot immediately eliminate them Fault

In addition, the traditional low-voltage power distribution box has a large volume, and the internal layout is very messy. When the internal electrical parts are damaged, it is not convenient for the staff to disassemble and repair
