Integrated driving system of electric car

Abstract

The invention provides an integrated driving system of an electric car, which is characterized in that the driving system comprises a high voltage case, a motor controller, a charging set, a direct-current converter and an electric appliance case body; the high voltage case, the motor controller, the charging set and the direct-current converter are assembled in the electric appliance case body in a unified and integrated manner; electric and electronic parts are connected in the electric appliance case body and conduct insulation protection; and a driving motor is directly fixed on the electric appliance case body to form integral hoisting and disassembly, and is mounted in a forward engine room in the car. The system integrates all high voltage electrical apparatus parts, provides a constant temperature environment condition, and has no exposed high voltage wires, so that the possibility of burning due to short circuit resulting from car collision is reduced greatly; the integral assembly and disassembly are realized; a loading space and reasonable support are considered integrally; the system is improved in the aspects of design and layout of the complete car, manufacturing and maintenance, cost reduction, economic performance improvement, mass production convenience, etc.; the succession of the traditional car is improved greatly; and the electrification course of the traditional car is accelerated.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to an integrated drive system for electric vehicles. Background technique [0002] Petroleum resources and environmental pollution issues have attracted great attention from governments and all walks of life around the world. Electric vehicles have become the future development direction of the automotive industry due to their advantages such as zero emissions, high efficiency, convenient driving, comfortable operation, and extensive power sources. However, most of the current electric vehicles are refitted on the basis of the original car body, which belong to modified or assembled electric vehicles. But there are problems in cost, quality and safety. For example: the scattered electrical components in the front cabin include motor controllers, chargers, DC converters, electric air conditioners, electric vacuum pumps, high and low voltage distribution box...

AI Technical Summary

Problems solved by technology

The different positions of these components in the front engine room form an intricate network of wires. Most of the motor drive assemblies are arranged on the lower layer, and the upper layer uses beams to support electrical components. It is inevitable that the wires are intricately connected. Although they are flame-retardant wires, they are The electric fire when the electrical appliances are short-circuited will bring great hidden dangers to safety; electric car fire accidents at home and abroad occur frequently, and the most popular American Tesla electric car came in and burned the car three times in a row
