Description

Light-weight three-electric-system practical training device for pure electric vehicle

Technical Field

The utility model relates to an automobile teaching technical field especially relates to real device of instructing of three electric systems of pure electric vehicles lightweight.

Background

The new energy automobile is different from the traditional automobile in the most core technology of 'three electricity', and comprises electric drive, batteries and electric control. Batteries are one industry related to chemistry, mechanical industry, electronic control, and the like. The key of the battery is the electric core, and the most important materials of the electric core are the anode and cathode, the diaphragm and the electrolyte. The anode material is widely known as lithium iron phosphate, lithium cobaltate, lithium manganate, ternary and high nickel ternary.

The electric drive consists of three parts: drive mechanism, motor, inverter. At present, the transmission mechanism of the electric vehicle at home and abroad is single-machine speed reduction, namely, no clutch and no speed change are realized. In the future, each electric vehicle enterprise will increase the complexity on the transmission mechanism, and simultaneously reduce the requirements on the motor and the motor rheostat, namely, improve the performance and reduce the cost. The motor is composed of three parts: the key points of the motor technology are the stator and the rotor. The rotor is a main driving motor of the new energy automobile, and the rotor plays all functions related to the movement of the new energy automobile. The motor of the new energy automobile has forward rotation and reverse rotation, wherein the forward rotation is forward driving, and the reverse rotation is reverse driving. In the process of forward rotation acceleration running of the new energy automobile, the motor is negative torque, and the accuracy of the torque means the acceleration speed of the new energy automobile. When the torque has errors, the new energy automobile needs to be accelerated by the motor, the mileage is converted into a battery which needs to consume the same energy, and the cost of the battery is higher than that of the motor, so that the efficiency and the performance of the new energy automobile motor are very important. At present, the click driving systems special for automobiles mainly have three types: a direct current click driving system, a permanent magnet synchronous motor driving system and an alternating current induction click driving system. The inverter is a device for converting direct current into alternating current, and if the inverter of an electric vehicle can support higher voltage, the corresponding voltage has larger charging current and larger power, which means that the charging is carried out by the same current, and the charging power can be amplified in equal proportion, i.e. the charging time is shortened. If the support voltage of the inverter is increased, the amount of heat generated by the inverter during charging is increased, and thus the problem of heat dissipation of the IGBT module in the inverter needs to be solved, which is a key problem for improving the charging efficiency.

The motor and the electric control system of the new energy automobile are used as the replacement of the function of the traditional engine (gearbox), and the performance of the new energy automobile directly determines the main performance indexes of the electric automobile such as climbing, acceleration, maximum speed and the like. Meanwhile, the working conditions faced by the electric control system are relatively complex: frequent start and stop, acceleration and deceleration are required, high torque is required during low speed/climbing, low torque is required during high speed running, and a large speed change range is provided; the hybrid vehicle also needs to handle special functions such as motor starting, motor power generation, braking energy feedback and the like. The motor electric control system is used as an important ring of a new energy automobile industry chain, and the technology and the manufacturing level of the motor electric control system directly influence the performance and the cost of a whole automobile. At present, the degree of autonomy of motors and electric control fields in China is still far behind that of batteries, part of electric control core components of the motors, such as IGBT chips and the like, still do not have complete autonomous production capacity, and whole vehicle enterprises and part enterprises with complete intellectual property rights of systems are still few.

The supply of car far surpasses the speed that maintenance personal increased, so lack the vapour in society and repair talent, but general school all teaches through the textbook, and is inoperable, and teaching is not directly perceived enough, and the student also is difficult to learn, is not convenient for understand, has just so appeared the real device of instructing of teaching on the market, or just the weight is too heavy too much to be convenient for remove and use, or just simple structure is seriously inconsistent with reality, has violated the first heart and the teaching quality of teaching.
