Pure electric coach intelligent power source cabinet

Abstract

The invention discloses a pure electric coach intelligent power source cabinet which comprises a first structural body, a second structural body, a third structural body, a fourth structural body, a fifth structural body and a sixth structural body. The first structural body is arranged at the upper end of the power source cabinet, the second structural body is arranged below the inside of the power source cabinet, and a shell is horizontally mounted above the first structural body. The power source cabinet has the advantages that the inside of a printed circuit board of the second structuralbody is in all-copper-plate linking and free of fly line; all parts are imported, thereby being lifelong; the power source cabinet is high in integration degree, clear in layout and good in anti-seismic performance; a .mm super-thick copper-skin circuit board is adopted for a small-current portion, and a copper strip structure is adopted for a large-current portion, so that overcurrent safe allowance is higher; the sixth structural body is provided with a CMS, real-time power consumption monitoring and overcurrent and overheat automatic power-off can be realized, the problem that a starting line is always difficult in setting a fuse is solved, and fireproof safety of a vehicle is improved greatly. The power source cabinet is firm, durable, good in social benefit and suitable for popularization and use.

Description

technical field [0001] The invention relates to a power supply cabinet, in particular to an intelligent power supply cabinet for pure electric passenger cars, belonging to the technical field of power supply cabinet applications. Background technique [0002] With the continuous development of automobile technology, the electrical equipment of buses continues to increase. Now there are 60-100 kinds of electrical equipment in the circuit system of a general bus. At present, most buses use CAN bus, which improves the safety of vehicle electrical circuits to a certain extent. For buses equipped with CAN bus system, CAN bus has controlled more than 50 lines such as lights and wipers. These more than 50 lines The line has been well protected by short-circuit and over-current intelligence. [0003] The remaining nearly 40 lines are still traditional passenger car lines, controlled by traditional ordinary distribution boxes and ordinary fuses. Due to the structure and cost of trad...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of low safety of the traditional power distribution box due to the structure and cost, the connectors are still made of domestic parts, the metal terminals are easy to loosen after repeated plugging and unplugging, and the flame retardancy of the electrical box material is not enough. High, thin PCB circuit board, overcurrent design safety margin is not high, etc., there are certain safety hazards, and the fire safety performance needs to be improved urgently, and a pure electric bus intelligent power cabinet is proposed
